Description

Environmentally friendly textile function enhancer and textile treatment method

technical field

The invention relates to a textile function enhancer and a textile finishing method, in particular to an environment-friendly textile function enhancer and a textile treatment method using nanometer functional peptide materials.

Background technique

Regarding the protection of textiles, the following three aspects should be considered: the first is to protect textiles from degradation due to exposure to environmental hazards; the second is to use textiles to protect people or things from environmental hazards; The third is to protect the environment from natural or man-made hazards from the composition of textiles.

In order to protect the material, some methods should be adopted. Based on Oko-Tex Standard 100, care should be taken to avoid the use of incorrect reagents for specific fiber types. An obvious example would be to avoid chlorine bleach or heavy metal agents coming into contact with wool or silk materials, or dyed fabrics that would fade when exposed to such agents. Some fabrics, such as acetate, are very sensitive to certain agents (for example, acetone and chloroform), and can be damaged by brief exposure to these substances. Heat irritation can cause damage to some heat-sensitive fibers, so care should be taken when drying and ironing nylon, polyester, olefin or other synthetic fibers.

For environmental reasons and to comply with existing emission guidelines, considerable efforts have been made in recent years to develop water-based polyurethane dispersions low in volatile organic compounds (VOC). Such low-solvent (low-VOC) and solvent-free (no-VOC) products have the advantages of environmental protection and economy. Due to their excellent performance, they have been widely used in solvent-containing products. The excellent properties of the polyurethane dispersed phase make many applications possible.

In the production of textiles, such as coating, spraying, crosslinking and bonding, polyurethane plays an increasingly important role. Solvent-free polyurethane dispersions with very high volume fractions of polyurethane polymers or fillers are especially suitable for textile applications. obtained in the production process.

The preparation of water-based polyurethane dispersed phases has been known for many years and is described in detail in numerous publications. For example, Houben-Weyl, Methoden der organischenchemie, volume E part I, pp, 1659-1681; D. Dieterich, Prog. Org Coat. 1981, 9, 281-330; J, W Rosthauser, K. Nachtkamp, Journal of Coated Fabrics 1986 , 16, 39-79; R. Arnoldus, Surf. Coat. 1990, 3 (Waterborne Coat.), 179-98.

Finally, U.S. Patent No. 5656701 discloses low-solvent or solvent-free cationic and anionic polyurethane dispersions based on various polymeric polyols, either through a prepolymer mixing process or using solvents with low NCO/OH ratios process preparation. Chain growth and stopping are controlled by specific hydrazine derivatives. The system described has a maximum solids content of 50%, but only one of the published examples has a maximum solids content of 40% polyurethane by weight.

Presently, modern technology is more concerned with protecting humans from harm due to exposure to environmentally hazardous agents. On a page on protective clothing in the new EU regulations, Nieves believes that advances in protective clothing may be driven by the market and government; he also believes that heat stress, comfort and barrier isolation are crucial in any type of protection. important.

Nano-peptide materials have a huge market, excellent inherent properties, and are environmentally friendly. Nano-peptide materials are widely sourced, reusable, and inexpensive, and are important substitutes for petroleum-based plastic products. Nanopeptides are complex macromolecules containing 20 different amino acids that can be made into biodegradable plastics. There have been many studies on the application of natural fiber powder materials, such as US. Pat. No. 11053291 and US. Pat. No. 11867959.

Chitosan also plays an increasingly important role in the production of textiles, such as coating, spraying, crosslinking and bonding. Now, in the United States and Japan, chitosan is also gaining economic importance as an alternative resource, which can be deacetylated from crabbing waste chitin. Chitosan is the second most abundant polysaccharide in the world after cellulose. The molecular weight of chitosan is 300000-500000g/mol. Compared with cationic starch, chitosan has higher cationic density. As a basic polyurethane it only acts as a cationic protective colloid in anionic systems which can be prepared in a simple and common production process.

The preparation of water-based chitosan has been known for many years and is described in detail in numerous published publications. For example US Patents 5,739,015 and 5,232,842 and 5,447,643.

For reasons of environmental protection and consideration of the guiding route from the existing treatment process, it has been developed over the years at high temperature (≥100°C) and low temperature (<100°C) conditions, at atmospheric pressure and at higher than atmospheric pressure Various methods, devices and compositions for textile finishing are presented. These most relevant methods, devices and compositions are discussed below. With respect to specific methods and apparatus, the prior art does not disclose specific steps or features of the present invention.

Disadvantages of current methods and plant processes for textile finishing using steam fixing devices are the necessity of a steam fixing step and high pressure conditions. Steam fixation has the following disadvantages: it requires a lot of energy to heat the steam, it dilutes the reagents because the steam condenses into water and mixes with the reagents, and it costs materials and time for textile finishing steam fixation. Another disadvantage is that a textile finishing process with a steam fixing process is not economical when processing small quantities of textiles.

The second part of the topic of textile protection is the use of textiles to reduce the harm caused by harmful substances to humans, which overlaps with some aspects of the first part. People don't like being shocked or having their clothes stick to their body due to static electricity generated or released by the clothes, they don't like rough fabrics and body contact even more so the modified compound is used as a softener to prevent fabric fraying by eliminating static discharge and static Adhesion can provide more comfortable clothes to wear.

Different from other ester-containing polymers, polyester is a heterochain macromolecule with a large number of carboxylate groups as the skeleton structure. It is well known to use a variety of fibers such as polyester, nylon, etc. to produce ultra-thin fabrics. These ultra-thin fabrics are used in many types of clothing, especially underwear, such as drawers, undershirts, stockings, pantyhose and the like. As we all know, the discomfort caused by sweat on clothes can be reduced and the comfort of clothes can be improved by using synthetic fibers with functions of moisture absorption, water absorption, moisture removal and drainage. Clothing that is in direct contact with or in close proximity to the skin (such as underwear, socks, mid-layers, sportswear, or other garments) may be subject to rapid wicking if worn.

Although polyester fabrics are suitable for many applications, it has been subjected to many modifications to enhance their physical properties and functional properties. For example in US Patent 4-105567, silicones have been used in combination with polyester fabrics to improve water resistance, smoothness and handling of polyester fabrics. Some patent applications have proposed modifying components for modification (for example, Japanese Patents 3-290461, 4-146952 and 4-325526). However, the result is a short-term improvement in the properties of the polyester fabric, over time and with repeated washing, the most important silicone will be washed away. Therefore, there is an urgent need to permanently incorporate finishing additives into polyester fabrics to permanently improve physical and functional properties.

Most organic polymers are poorly conductive and therefore have a tendency to accumulate static charges. As such, they are not stable for applications requiring semiconducting properties without further modification.

Polyisocyanate-based polymers are used in a wide variety of applications. Some applications are more sensitive than others to damage and discomfort from static buildup and extreme discharges. These demanding areas include, for example, the packaging of electronic components, medical applications in operating rooms where an extremely dust-free environment is required. Clothes or equipment made from or containing polymers of polyisocyanates are sensitive to the build-up of static electricity, which may introduce dust into the cleanroom or cleanroom.

For example, it is known to incorporate conductive fillers such as fibers, powders and particles into polymers to enhance conductivity and thereby reduce the potential for static buildup. However, in order to obtain good electrical semiconducting properties or electrostatic discharge properties, such fillers usually have to be loaded more than 15%, or more. Such fillers may be detrimental to the polymer and its physical properties, eg, may increase its brittleness.

In US Pat. Nos. 4,617,325 and 4,618,630, the obtained polyester has antistatic properties through the use of additives containing ionic salts in combination with reinforcing agents. The enhancers are carboxylates, fatty acid salts or phosphates. Incorporating ionic salts into urethanes may bring about other properties, such as hand properties.

detailed description

The disclosed content of the present invention will be described in more detail below in conjunction with the attached cases, where the cases are preferred embodiments. However, the disclosed content of the present invention can be implemented in different forms, and should not be construed as a limitation to the present invention, but these embodiments are provided to make the disclosed content deep and complete, so that those skilled in the art can fully understand the present embodiment range.

The invention discloses a new technology of an environment-friendly functional treatment process. Consisting of strengthening agents containing two main components of water-based polyurethane and biofunctional materials, the final treated textile material improves the mechanical properties of the textile and increases the antistatic properties.

Example 1

The polyester fiber was prepared from woven polyester obtained from BAJA Industries. The textiles are cut into small pieces ready for processing. Treatments include:

The process has the following steps:

Firstly, soak the textiles at 20-30°C for 20 minutes, then pad them, and the excess rate is 80%; dry them at a temperature of 90°C, and the drying time is 3 minutes; Combined into the polyester fiber, the baking temperature is 160° C., and the baking time is 3 minutes.

After treatment, the treated textile material improves the mechanical properties of the textile and increases the antistatic properties. Used in physical tests to check antistatic properties and feel. Samples were rinsed and dried. Antistatic property is measured by electrostatic voltmeter R-4021 and evaluated by resistance of textile or yarn. The resistance electrode is inserted into the grounded socket of the input to test the sample clamped between two spring clips. Subsequent operation of the button pressurizes the isolated input to 150V. At the same time, measure the charging time with a stopwatch until the tension value drops to the middle value. The median value is marked with a dotted line and an "R" in the galvanometer. This method is called the integral method. The surface resistance is determined by the following formula:

Measuring time (s)×1011=R(ohms)

If a resistive electrode is used, the input terminal is energized until the tension drops from U to U/2. This time is t. R can be calculated by the following formula:

R(surface resistance)＝1approx×10 ¹¹ ×t(s)

Capacitors can be connected in parallel with the sample, any of which can cover any desired resistance range. When measuring, measure the charging time according to the STATIC VOLTMERTER R-4021 standard, the room temperature is 20°C, and the humidity is 65%. The results are: the charging time of the untreated sample is 61s, and the surface resistance is 6.1×10 ¹² ohms. The treated sample had a charging time of 0.417s and a surface resistance of 4.17×10 ¹⁰ ohms.

The treated polyester fiber samples after washing showed a 3%-4% improvement in hygroscopicity without losing other valuable properties. Treated polyester fibers are softer to the touch. The bending stiffness of the treated polyester fiber is reduced, and the tear strength and smoothness are improved. The air permeability of the samples was tested according to BS5636-90 "British Standard Fiber Fabric Air Resistance Test Method (BS5636-90 1990)". Compared with the untreated sample, the air permeability of the treated polyester fiber increased from 9.45CC/s/cm ² to 11.52CC/s/cm ² ; the test pressure was 100Pa.
