1240021 A7 B7 V. Description of the invention (I) '~' ~ — ~ | Invention back t In recent years, consumers have preferred the more beautiful and comfortable 100% cotton fabric: 'especially in terms of clothing, so the use of synthetic fabrics has been reduced And blending: However, the use of 100% cotton yarns and fabrics also has their drawbacks, including shrinkage and wrinkling. The most common way to control shrinkage and wrinkling of cotton in outerwear is to cross-link cotton fibers with formic acid-based resins. However, paniculata is considered an I-hazardous, chemical that is hazardous when handled during processing. In addition, because formazan is a known carcinogen, it is also considered dangerous for fabrics that come into contact with the body. In addition, if we use cotton-based resin to control cotton or cotton blends: | When the fabric shrinks and wrinkles, it will make the abrasion resistance and strength properties of the fabric worse, making it easier to abrasion, wear, formation of holes and rub mark. Although non-formaldehyde resins (such as polycarboxylic acids) have been invented, they are less effective and more expensive, and they are also prone to loss of fabric strength. Printed by a consumer cooperative of the Central Standards Bureau of the Ministry of Economic Affairs, a textile factory pre-washes fabrics to control shrinkage. It is also unsatisfactory because it wastes energy and gives new clothes a worn appearance. Some people have used mechanical compaction to control the shrinkage of cotton fabrics. However, this process is costly because it will result in modest work losses, and it is not a once and for all solution because the compacted garment is easy to return to the size before compaction. In addition, none of these methods address the tendency of cotton to wrinkle easily. Therefore, the use of resin to treat cotton is currently the preferred method for controlling shrinkage and wrinkling of cotton fabrics. After the introduction of self-hydrophobic synthetic textile fibers (such as polyester, polypropylene, polyolefins, polyacrylates, and nylon, etc.), filament yarns are compared with staple fibers because they are stronger and more durable, while wrinkling and The shrinkage problem applies the Chinese National Standard (CNS) A4 size (210X297 mm) 1240021 kl B7 than the paper size. Printed by the Consumer Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs 5. The invention description (7, so it became popular. Made with these fibers Fabric can be shrunk with a yarn that exceeds the heat treatment point of synthetic fiber polymers. Products made from synthetic yarns have excellent strength f, dimensional stability, and resistance to washing, dry cleaning and money Fastness. Polyester knitted and woven fabrics made of polyester have become very popular in the late 1960s and throughout the 1970s. Recently, filament polyester fibers have also been cut into staple fibers, which can be spun into 100 = short Fiber yarn or blended with cotton or other natural fibers. However, synthetic yarns and fabrics made from these yarns have many poor properties, including a flashy synthetic look, slippery The "healthy touch" of human health, limited moisture transport = force, and easy to accumulate static charges. In addition, "fibers are easy to fuzz when made into short fibers, and are easy to pickle when made into long green. Make cotton The conventional method of blending with synthetic materials is not too successful, because when cotton and polyester are blended mechanically or in close contact, they are prone to fluff, broken filaments and shrinkage, may accumulate static electricity, and are uncomfortable to wear. In recent years, because consumers prefer 100% cotton fabrics that are more beautiful and comfortable, the use of polyester and polyester blended fabrics has been reduced. Over the years, people have produced yarns with a natural fiber sheath / synthetic fiber core configuration. Thread (U.S. Patent Nos. 4,711, 〇79, 5,497,608, 5,568,719, and 5,618,479). It is well known that the method of spinning both uniform and composite yarns is loop Spindle spinning, this method can produce high-quality strong yarns, and the capital investment per spindle is low. However, ring spinning is a slower process, which can only spin about 0 to 25 feet per minute Of yarn Plus the cost of the finished product.

Description of the Invention (:)) The situation of uneven distribution printed by the Consumer Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs, including some sections that do not contain any cortex at all. In addition, 'there is no other known process that can produce the strength or feel of the ring-spun yarn', so if the strength and feel of the yarn are required, this process is used, so that the cost is high. No less. The concept of using a graft or coextrusion to produce a sheath / core fiber composite is a relatively new attempt to solve this problem (US No. 3,824,146, No. 5, _, 954, No. 5,272,005, And Patent No. 5,387,383). In this process, the synthetic yarn core fiber is passed through a fiber-coated mold, where it is brought into contact with the adhesive core. Passing the treated fibers through a sulphuric acid bath produces a rhenium coating. The composite fiber thus obtained has the mechanical properties of the core fiber, and the surface texture of ochre purple. In general, the surface of the snail is not very good in adhesion to the yarn core, especially when the latter has a smooth surface. It has been suggested that there are various adhesion promoters with various effects, but the long reaction time required for acid curing makes this method expensive and slow. Therefore, this technique is required to produce fabrics that have both the positive qualities of cotton and synthetic materials, while eliminating the negative qualities. In addition, it is also necessary to be able to quickly and economically perform current textile manufacturing practices, such as sandblasting, weaving, and dyeing. Introduction to the Invention The present invention refers to a fabric, a garment, a woven fabric, or a non-woven fabric made of synthetic fibers (hereinafter collectively referred to as "r-based" and "fiber-based"), or the treatment of individual synthetic fibers or yarns. A method of creating a carbohydrate skin that is permanently attached to the various synthetic fibers of the substrate.

Description of the invention (bucket) The printed products of the Consumer Cooperatives of the Central Government Bureau of the Ministry of Economic Affairs of the People's Republic of China have the intentional nature of cotton material, which is also a carbohydrate. This treatment produces a substrate that combines the best properties of the synthetic yarn core with the best properties of the carbohydrate skin. For example, the substrate exhibits the mechanical properties of synthetic yarn core fibers and the surface properties of cotton. In addition, if desired, this technique is applied to individual synthetic fibers or yarns before weaving, knitting, stitching, or other methods of forming a woven or non-woven substrate. In particular, the process of the present invention involves contacting a material or substrate containing synthetic fibers with an aqueous solution containing a water-soluble carbohydrate polymer or monomer. Next, a suitable cross-linking agent is used to cross-link the carbohydrate monomers & polymers to each other, thereby forming a durable stone dehydration sigma skin layer or encapsulation layer around the synthetic fiber. The substrate thus treated has processing properties similar to those of cotton and, even after repeated washing, still exhibits hydrophilic properties. In comparison, substrates made from synthetics that are not so treated are often hydrophobic. One advantage of each method over conventional techniques is the ability to directly pad / dry / cure the dyed and finished synthetic fabrics. In addition, this process is cost-effective and can easily be completed with currently used textile finishing equipment. The present invention also refers to a kind of fabric, clothing, woven fabric, or non-woven fabric ("base" and "fiber base") made of natural fibers, or treatment of individual fibers or yarns to produce a permanent The method of sticking to the peribasal fiber = ¼ water compound cortex. This creates a desired shell with a cotton-like surface, while retaining some of the functional properties of the natural fibers of the core.

Application of the cortex: In the preferred embodiment of the present invention, The synthetic, artificial or natural yarn core material in the form of a fabric is passed through a bath containing an aqueous solution containing water-soluble carbohydrates and a cross-linking agent and, if necessary, a suitable cross-linking agent catalyst. This bath is referred to herein as "carbon water Compound polymer skin formula "or" skin formula ". The fabric is paddled to remove excess liquid, heated to dryness, and then cured under conditions sufficient to allow a chemical reaction between the crosslinker and the carbohydrate. A cross-linking agent is formed between these compounds to form a thin film of carbohydrates on the surface of the yarn core. This layer is called here "Carbohydrate Encapsulant", "Carbohydrate Cortex", "Sheath", or "Skin". This general method can also be applied to individual fibers, ribbons, and moldings. Spray, foam or This technique can be used in any other way that a substrate can be brought into contact with a treatment solution.

Many cross-linking chemistries are known, including polycarboxylic acids, aminoplasts (N-methylol), isocyanates, epichlorohydrin, and crosslinkable silicone polymers. Currently preferred crosslinking agents are polycarboxylic acids and N-methylol compounds. Polycarboxylic acid cross-linking agents include butane tetracarboxylic acid, polymaleic acid, polyacrylic acid, citric acid, and the like. Catalysts known in the art for use with polycarboxylic acids include sodium phosphite. If the molecular weight of the polycarboxylic acid is large (e.g., polyacrylic acid having a molecular weight > 10k) ', no catalyst is required.

In addition, other Properties can also be processed =, such as fiber redundancy, fabric feel or "hand", static dissipative ability, and inter-fiber friction noise characteristics. This manual includes natural or artificial substrates such as wool and other keratin fibers , Linen, camp, and nylon, etc. When the carbohydrate skin is applied, the intended properties of the cotton-like surface are applied, while retaining some of the functional properties of the natural fibers of the core. For example, wool fabrics have Time insulation, good drying, elasticity, ductility, drape, and anti-allergy properties. However, some people are allergic to wool, and it will shrink and flock after washing, and at the same time There is a tingling sensation near the skin. When the cellulose outer layer of the present invention is used, the wool can be made shrink-proof, not sensitive, beautiful and comfortable, while retaining its original beneficial properties. In one embodiment, this The process involves contacting keratin fibers with a finishing agent composed of a combination of polyelectrolyte carbohydrate polymers. Therefore, wool fibers, textiles or fiber substrates are coated with a positively charged polysaccharide, such as amine-containing chitosan, It is then coated with a negatively charged polysaccharide, such as alginic acid containing a carboxyl group. The oppositely charged polymers will form a composite skin layer on the wool fiber, making it less likely to cause an allergic reaction. The composite formed It does not dissolve in organic solvents commonly used in general dry cleaning, such as tetragas ethylene, which makes this coating durable. The properties imparted by the carbohydrate skin or encapsulation do not interfere with the standard properties of the fabric; that is, the skin Does not significantly increase the diameter of the fiber, nor fills the space between the fibers with a large piece of sheath material, or blocks the weaving. 9 Paper scale applicable Chinese National Standard (CNS) Α4 Specification (210'〆297 mm) 1240021 A7

In addition, the treated fabric does not feel like polyester, but instead has improved hygroscopicity. The synthetic and natural textiles prepared in accordance with the present invention have a variety of uses, including but not limited to: clothing 'decorative fabrics and other home decorative fabrics, hospitals and their medical uses, and automotive applications and industrial uses, such as

Adanur, S., Wellington Sears Handbook of Industrial Textiles, those listed on page ^ Chuan (Lancaste, Penn, USA, 1995). Post-processing of cotton garments in general It is in the form of ready-to-wear, in order to increase the "she 丨" or aesthetic appeal to consumers. When processed in a garment, certain properties can be imparted to the textile, including soft feel, shrinkage control, durable pressing, and an unusual and unique appearance, depending on the processing used. For example, twill jeans are often wet processed to improve softness and shrinkage control before they are sold, and softeners are often used in the final wash. Molten rocks, pumice, bleach and / or cellulase can be used to accelerate the abrasion of garments to give a worn appearance. These and similar post-processing processes can be applied to the present invention to improve the aesthetics of the garment. The carbohydrate skins used to encapsulate synthetic, artificial, or natural fibers allow many post-processing techniques for cotton to be applied to the synthetic, artificial, or natural fabrics that have been treated in accordance with the present invention. Adding auxiliary ingredients to the skin layer: When a carbohydrate encapsulating layer is applied to a fabric according to the present invention, it provides an opportunity to finish the fabric with various auxiliary ingredients that do not have a durable ability to bind to the fabric at the same time. In this way, the carbohydrate cortex is 10 paper sizes applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm) I Aw · IT (Please read the precautions on the back before filling this page) 1240021 Employees of the Central Bureau of Standards A7 --------- B7 V. Description of the invention (,) * Used as a binding agent to make non-affinity (ca_substantive) auxiliary ingredients not co-applied with the skin finishing agent to have durability. Alternatively, the auxiliaries may have affinity for the carbohydrate finishing agent and be encapsulated after application of the carbohydrate; it may then be used in processing. Regardless of which method is used, the base fabric is assigned: many properties that would not be possible without this packaging layer. Some examples of co-ingredients include infrared absorbing compounds that can be permanently bonded to fabrics so as not to be detected by night vision equipment. Examples of infrared absorbing materials are carbon black, chitin resins, or compounds that generally absorb electromagnetic radiation having a wavelength of 1000 to 1200 nm. Fabrics treated with an encapsulating layer containing an infrared absorbing material produce infrared absorption and other beneficial properties that are part of the encapsulating layer; the fabric may be important in military applications. Similarly, ultraviolet light blocking compounds can be added to protect the wearer or the fabric material itself from ultraviolet light. Pigments or dyes can also be added to this outer layer to dye the fabric. Magnetic colloids can also be embedded in this cortex to provide data storage capabilities to the fabric. It is also possible to add bioactive agents (e.g., pesticides, antimicrobials, and pharmaceuticals) 'as well as flame retardants and antistatic agents. Odor-sucking compounds and neutralizing agents (such as activated carbon or cyclodextrin), or materials that are intended to be used, such as 'hydrolyzed bonding agents and long-term release materials', can also be applied according to the present invention. In the detailed examples, colloids commonly known as particles and average particle sizes between 10 and 500 nm are added to the encapsulation skin formulation and bonded to the treated fabric. These colloidal particles are too small to be seen even with a general microscope, so individual particles are not noticeable on the fabric.

I 1240021 Printed by the Consumer Cooperatives of the Central Bureau of Standards of the Ministry of Economic Affairs A7 B7 V. Description of Invention (P) For example, gold and silver are very important because of their light-absorbing (and therefore coloring) properties. Metal glue systems absorb light at the maximum absorption wavelength associated with the metal type and particle size. Among the inventions related to biological and toxicity tests, they have been found to have a wide range of uses. U.S. Patent No. 5,851,777 issued to Hunter et al. Has disclosed the use of colloidal particles that bind to particularly cohesive organisms or poisons to bind to the complexes, in which colored metal colloids are specifically listed as an application for this invention . When a specific biological or toxicant moiety is added to a solution containing metal colloidal particles of a binding complex, this combination results in particle aggregation and shift of the maximum absorption wavelength (ie, the color of the solution). Hunter et al. Also disclosed several related patents on colloidal particles using a cohesive complex. An important one of these patents is the ability of the ligand to adhere to the particle surface via an intermediate polymer. Intermediate polymers are either physically entrained (partially) in the particles ’or are permanently absorbed on the particle surface. The necessary intermediate polymer contains a reactive group that allows it to adhere to the ligand. The disclosures of U.S. Patent No. 5,851,777 and those patents cited therein are incorporated herein by reference. U.S. Patent No. 6,136,044 to Todd has disclosed the use of metal colloids on dyed substrates such as fibers, yarns and textiles. The substrate to be colored is first placed in a bath containing a reducing agent preferably having an affinity for the substrate. After sufficient time is available for the reducing agent to absorb, the substrate is removed from the bath, selectively dried, and placed in a second bath containing a dissolved metal salt corresponding to the alpha metal victory . The absorbed reducing agent will reduce the salt into colloid and use it as a nucleation field for particle growth. 12 This paper is again applicable to China National Standard (CNS) Α4 specification (210 parent 297 male sauce) IT (Please read the Note: Please fill in this page again) 1240021 A7 B7 V. Description of Invention (I 丨). The particles obtained are absorbed into the substrate or are selectively entangled with the substrate. As a result, the substrate is colored to have a color corresponding to parameters such as metal type, particle size, and amount of metal on the substrate. When each of these parameters can be controlled, various colors can be obtained. As a result, the color of the substrate is both washable and sun-resistant. This method does not require the use of polymeric cement or other additives to provide color fastness. /, Certain metal colloidal suspensions, especially silver and copper, especially silver, have been proven to have bactericidal effects on many bacteria. The Merk Index (10th edition) emphasizes that silver “has been used to purify drinking water because of its ability to kill bacteria and lower life forms.” In one embodiment of this aspect of the invention, a metal gum system is added A cortical formulation to color the fibrous substrate treated by this formulation. In another embodiment, a metal colloid with antimicrobial properties, preferably silver and copper, but most preferably silver, is added to the cortical formulation. The fibrous substrate treated with this formula is therefore antimicrobial. Another embodiment is to add a sufficient amount of metal colloid to the skin layer formulation to make the surface of the treated substrate conductive, while the untreated substrate is almost or completely non-conductive. The treated fibrous substrate thus has antistatic properties. Printed by the Consumer Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs (please read the notes on the back before filling this page) S metal colloids can be added to the cortical formula in various ways. One method is to prepare metal colloids before adding them to the cortical formulation. Metal colloids can be prepared by reduction of metal salts using chemical, electrochemical or light shot processes known to those skilled in the art. For example, silver salts can be reduced to metallic silver with sodium borohydride (, electric potential (electrochemical) or visible light (radiation). The so-called passivation y ”can be used to form metal colloids. These additives can be used as particles. 13 1240021 Printed by A7 B7, Consumer Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs 5. Description of the Invention (| y) Long nucleating agents can also coat the surface of particles to minimize the degree of particle aggregation. Common passivation agents include bovine serum proteins , Casein, and milk proteins (such as milk powder). Passivating agents preferably contain functional groups that react with each component of the skin formulation. Such passivating agents are preferably physically entrained into colloidal particles to make colloidal particles easier. Stuck in the cortex. Metal colloids can also be prepared directly in the cortical formula solution or with more than one of these components. A soluble metal salt of the relevant colloid is mixed with one to all components of the cortical formula and then exposed Under the reducing conditions that can induce the formation of gum 4. One possible advantage provided by this method is that a viscous solution between the cortex formula and all can prevent primary colloidal particles In addition, more than one component of the cortex formulation can be used as a passivating agent for colloidal particles. Adding a colorant: In another embodiment, the present invention can be used as a binder to fix the colorant to the fiber. The term "colorant" in the contents of this specification and in the scope of the patent application refers to pigments (non-water-soluble) or dyes (water-soluble). Although one of the main purposes of carbohydrate packaging and finishing is to make synthetic fibers have natural fibers (such as cotton) The feel of this product is quite different from cotton fiber in terms of chemical and physical properties. There are at least three major differences: First, the finishing material can be chemically similar to cotton fiber, not the same. Chemical differences can have a significant impact on the efficacy of various dye classes. Second, the cortex is highly cross-linked, so it can tightly entangle the mother fiber IT (please read the precautions on the back before filling out this page) 14 1240021 A7

Outer staining. Some of the dyes commonly used on the outer layer include those that have the following properties on the surface of carbohydrates: a) physically absorbed (direct dyes), b) mechanically retained (reduced dyes and sulfur dyes), or c) chemically reactive against f By. This technique provides a method that can produce numerous effects and colors. The red can be selectively ground or hydrolyzed to produce a low gloss (light color on the upper part of the dark color), a two-tone (two different colors) and "distressed" (outer layer) 'can be achieved by the present invention. Coloring method: The "single-step method" and "multi-step method_" as referred to in this specification refer to the number of steps required to process the fabric or fiber substrate that is to contain the colored outer layer. The "single-step method" involves There may be several steps before the substrate, but the colorant and the skin layer are applied to the fabric at the same time. In the multi-step method, the colorant and the skin layer are applied in different steps. The easiest process is to add the colorant to the base carbohydrate skin formulation before finishing the fabric. This coloring formulation is then applied according to conventional methods, such as dipping, spraying, or padding, the latter of which is preferred. The colorant can be fixed in the skin layer by means of physical entanglement or encapsulation, electrostatic coordination, or chemical adhesion to the skin layer material '. In addition to the ease of processing, another advantage provided by this method is that it can obtain various color depths. The thickness of the sheath layer is at most less than one tenth of the thickness of the fabric fibers it encapsulates, or even less. If the colorant is uniformly distributed over the entire skin layer ', the application amount of the colorant can be maximized. Even distribution also helps ensure that the color fastness of the colorant is good or not easily discolored by washing or other abrasive conditions. Other potential advantages include that the textile mill applies the Chinese National Standard (CNS) A4 specification (210X297 mm) throughout the 16 paper sizes.

Packing II Printed by the Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs 1240021 Printed by the Consumer Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs A7 B7 V. Description of the invention (\ ζ) It is not necessary to add equipment for applying colorants during processing, which is easy during the padding process It achieves the effect of uniform application and color depth, and there is no problem of cleaning or handling of the finishing of the colored skin layer. One step method: This method is to apply a colorant to a fabric that has been previously finished with a base carbohydrate cortex formulation. The formulation to be applied may optionally include a component which is very compatible with the colorant. Alternatively, the finished fabric may optionally be treated with a component having an affinity for both the skin layer and the coloring agent before being contacted with the coloring agent. One potential advantage of this method is that it can use pigments that cannot be mixed into the skin formulation without altering the stability and durability of the skin. Another advantage is that a significant aesthetic effect can be obtained when compared to a single step method. Disadvantages include limited types of effective colorants, and colorants may accumulate on the surface and cause problems such as color depth, abrasion fastness, and poor color fastness. The sheath layer is tightly cross-linked, which prevents the colorant from penetrating to a certain depth. The various ways of coloring with known dyes will be explained later. The aforementioned one or two methods can also be applied to these methods. Mordant fixation: Certain types of metals called mordants can form strong bonds to chemically reactive groups such as carboxylates and phenol functionality; the obtained mordant complexes do not dissociate in water and often belong to Not water soluble. Since chemical groups of mordant reactions have been found in many types of dyes, mordant complexation provides a way to immobilize insoluble dyes on or in a substance, especially if the substance is also complexed with mordant metal.

The mordant and mordant reactive dye are combined in an amount, order, and manner that easily achieves the intended properties of the coloring formula. The obtained The formulation should be stable, for example, the mordant compound does not precipitate. If the mordant is coordinated with the reactive group of the water-soluble polymer of the base cortex formula, it is easy to achieve stability. However, if the cortex formula is viscous, the mordant compound will be stable. Can be moderately suspended in this formula, so the amount of water-soluble γ-mordant should not be added based on the principle that the aggregation in the base cortex formula does not cause instability. Then apply the colored cortex formula to the fiber substrate and then treat the substrate Curing to fix the sheath layer in place. Using mordant complexation and physical packaging, the dye is permanently bonded to the sheath layer. Printed in a multi-step embodiment by the Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs It is mixed into the cortex formulation in an amount and manner that is easy to achieve the desired properties of the coloring formulation. Layers form cohesion, but the formula obtained must be stable, for example, the mordant compound cannot be precipitated. If the mordant is coordinated with the reactive group of the water-soluble polymer of the base cortex formula, stability is easily achieved. However, if the cortex The formula is viscous enough that the mordant compound can be suspended in this formula moderately, so there is no need for water solubility. The amount of mordant added should be based on the principle that the aggregation in the base cortex formula will not be 40% unstable. Then modify the mordant formula Apply to the fiber substrate, and then cure the treated substrate to fix the sheath layer in place. Then, the fiber-wound fiber substrate is contacted with the mordant reactive dye using techniques known to those skilled in the art. In a preferred method, The reaction group of the fibrous substrate on the wood is easily exposed to the solution containing the dye at the temperature and duration of the compound of the mordant metal that is stuck into the skin. Then the dyed fibrous substrate is dried. Because the tightness in the skin is tight Cross-linked, so these 18 paper sizes are applicable to China National Standard (CNS) A4 specifications (210X297 male feet) 1240021, invention Ming (Central Bureau of Standards, Ministry of Economic Affairs, Consumer Cooperatives, Printed Dye is bonded to the outer layer of the cortex in a durable manner. Exposed in the example of the example, the fiber base where the cortex is entangled is surrounded by mordant metal. The exposure reaction to the second substrate is consumed on the substrate. The fibrous solution treated with the mordant is then taken out, selectively dried, and then exposed to a solution containing a mordant = active dye. The dye system is used The method of complexing with the mediator on the surface of the cortex is consumed in the cortex. Other examples of the extinct dyeing method are easy to identify; although not mentioned here, all these examples are considered to belong to the present invention. Scope. Pigments, vat dyes, and sulfur dyes: Vat and vulcanization dyes are a mixture of dyes and pigments. They are poems and their pigments. They are dyed by vitamins (if they are chemically reduced) In the form, they are water-soluble dyes, but when oxidized, they become insoluble pigments. In the case of conventional fiber dyeing, the fiber system is exposed to a reduced form of the dye to facilitate penetration of the dye into the fiber. The fibers are then exposed to oxidizing conditions to induce the formation of insoluble particles absorbed within the fibers. This promiscuous behavior provides a variety of methods that allow these dyes to act as colorants in skin formulations. ^ In a single step process, pigments or redox or sulfur dyes are dispersed into the carbohydrate skin formulation. Another option is to add interfacial activity to promote dispersion! The sticky base cortex formula also helps increase dispersal time by slowing the sink rate. The colorant can be added in the form of a solid powder or an aqueous dispersion. In both cases, and especially the latter, the addition of colorants should not be diluted in the skin formulation to such an extent that the skin loses its durability or does not exhibit its properties effectively when applied to a fiber substrate.

Description of the invention (丨 &) ^ ~ pigments are commercially available from BASF under the name HiFastTM. The pigmented cortex formulation is then applied to the substrate and cured in place. The colorant is dispersed throughout the skin layer and is held in place by physical packaging. In another one-step method, a leuco-reducing or sulfur dye solution is added to the skin formulation, and the combined skin formulation is oxidized to form a colorant dispersion within the skin formulation. The pH of the colored cortex formulation may need to be selectively adjusted within the range required by the base cortex formulation. It is preferable to add a component which can significantly increase the viscosity of the solution. The leuco dye is then oxidized to form a suitable particle dispersion in which the skin component is partially encapsulated. If necessary, add the remaining components of the base cortex formula and adjust the pH to the necessary specifications for crosslinking. This dyeing formulation is then applied to a fibrous substrate and the substrate is cured and fixed to the skin layer. Encapsulated colorants maintain color fastness in a physically tangled manner. Other examples of this dyeing method are easy to identify; although not described here, all these examples are considered to be within the scope of the present invention. Modified reactive dyes: Commercially available reactive dyes are generally used to dye cotton and cellulose-based fibers. They contain functional groups that react with nucleophilic sites under high alkaline and high temperature conditions. Because dyes become covalently bonded to fibers, they have excellent color fastness. The leather material of the present invention may not contain an appropriate reaction site, and may not be applied under highly alkaline conditions, and both cases can prevent the reaction with a commercial reaction dye. Another difficulty in using reactive dyes is the hydrolysis of the reaction site. Hydrolysis competes for the hydroxyl groups of cellulose required for the dye reaction, which results in inefficient use of the dye. ’I ------ ^, 玎 ----- 0 (Please read the notes on the back before filling this page)

Description of the invention ((1) The aforementioned difficulties can be circumvented in various ways. One of them is to react with a difunctional reagent first and The dye is modified; one function of the reagent reacts with the dye, and the other function is bonded to the dermis. The modified dye is then added to the base carbohydrate cortex formulation, which can then be applied to the fiber substrate in a single step . Another way is to add a bifunctional reagent to the base cortex formulation. This bifunctional reagent has a functional group that will preferentially react with reactive dyes, and the other functional group is bonded to the cortex material. The cortical formulation is applied to the substrate, and then cured to fix to the cortex and bind the reagent. Then, the treated substrate is dyed with a reactive dye in a multi-step method, wherein the reactive dye will preferentially interact with another functional group of the reagent In another way, the cortical formulation is blended with a difunctional reagent, and the reactive dye is made with two difunctional reagents. The two reagents each contain at least one functional group that will preferentially react with one of the functional groups of the other reagent. No matter one step or multiple steps can be used in this case. Similar ideas have also been proposed by Lewis and Vigo (Lewis, D.M., Lei, X_; AATCC International Conference and Exhibition Book of Papers, October 4-7, 1992, pages 259-265; Vigo, T.L., Blanchard, EJ; AATCC International Conference and Exhibition Book of Papers, 1996, pp. 203-208; Vigo, TL, Blanchard, EJ; Textile Chemist and Colorist, vol. 19, No. 6 (1987); U.S. Patent No. 4,678,473). However, in In these cases, the cellulose fiber is modified instead of the skin layer. Examples of functional groups that preferentially react with reactive dyes include amines and thiols. These groups are far more nucleophilic than water and can Eliminate waste 21 This paper size is applicable to China National Standards (CNS) A4 (210X297 mm) (Please read the note on the back —: write this page) *?

Hydrolysis of invention description (:?-). Amines are preferred. Examples of functional groups that can react with the components of the carbohydrate cortex include but Not limited to hydroxyl, amines, thiols, carbamate condensate, cyclic anhydrous compounds of five and six atoms, can form dicyclic compounds of cyclic anhydrous compounds of five and six atoms, and block isocyanates g will. Non-limiting examples of monofunctional reagents include ethylenediamine, ethanolamine, and aminosuccinic acid. In addition, it has been found that a dye formulation provided by incorporating a dye having a carboxylic acid functionality or a 1,2- and 2-layer structure into a skin layer formulation can produce a washable and abrasion-resistant color on a fiber substrate treated with the formula. Dyes without these functional groups are not washable and abrasion resistant. Examples of dyes having a carboxylic acid group include methyl red, mordant yellow 12 and mordant orange 1. Examples of dyes having a 1, 2 and 2 meridian structure include alizarin and purple essence. Without being bound by theory, it is believed that the chitosan group reacts with the nucleophilic portion of the cortex material, while the warp groups of the 1,2,2 meridian structure react with the electrophilic portion of the cortex material. The preferred nucleophilic moiety is a mesogenic group, and the preferred electrophilic moiety is a carboxylic acid group. Dyes are held in the cortex by covalent bonds, so this dye works according to the type of "reactive" dye. Other examples of this dyeing method are easy to identify; although not described herein, all these examples are considered to be within the scope of the present invention.
