10-30 parts of high-temperature resistant fiber;
5-20 parts of polyaryl oxadiazole fiber;
20-40 parts of flame-retardant viscose fibers.
Wherein,
the high-temperature resistant fiber is one or a mixture of polysulfonamide fiber and aramid 1313 fiber.
The fabric is made from staple yarns.
The wear-resistant flame-retardant comfortable fabric containing the short fiber blend is a woven fabric or a knitted fabric.
The invention also discloses application of the wear-resistant flame-retardant comfortable fabric containing the short fiber blend in protective clothing or protective products.
Specifically, in the present invention:
the flame-retardant vinylon fiber is prepared by grafting a compound containing flame-retardant functional elements (halogen, phosphorus, nitrogen and the like) on a polyvinyl alcohol (PVA) macromolecule, or adding a flame retardant, blending, and then carrying out the technical processes of solution spinning, stretching, heat treatment, formalization and the like. At present, the main flame-retardant vinylon varieties are as follows: polyvinyl chloride fiber, CY841 fiber (trade name of decabromodiphenyl ether/antimony flame-retardant polyvinyl), high-strength flame-retardant polyvinyl alcohol fiber (decabromodiphenyl ethane flame-retardant high-strength polyvinyl alcohol fiber), and high-strength halogen-free flame-retardant polyvinyl alcohol fiber (flame retardant: DDPS flame-retardant fiber).
Taking CY841 fiber as an example, the fiber uses decabromodiphenyl ether and antimony trioxide as flame retardants, and adopts a common wet spinning method to produce flame-retardant vinylon; compared with the common vinylon, the decabromodiphenyl ether flame-retardant vinylon has smaller difference of the skin-core layer structure, the flame retardant is uniformly dispersed in the fiber in a granular form, and the continuous phase is PVA (polyvinyl alcohol), so that the flame-retardant fiber with less flame retardant on the surface layer is obtained.
The high-temperature resistant fiber mainly comprises polysulfonamide fiber and aramid fiber 1313 fiber.
The polysulfonamide fiber is also called polysulfonamide fiber, is called PSA fiber for short, and is named as a Teran (TANLON). Polysulfonamide is an aromatic polyamide fiber with a special structure known as polyphenylsulfone terephthalamide fiber, which is made of a polycondensate of 4,4 '-diaminodiphenyl sulfone, 3, 3' -diaminodiphenyl sulfone and terephthaloyl chloride. The aromatic polysulphone fiber introduces a p-benzene structure and a sulphone group during production, so that the amide group and the sulphone group are mutually connected with the p-phenyl group and the m-phenyl group to form a linear macromolecule. Because the sulfonyl group- (SO 2) -with strong electron-withdrawing property exists on the main chain of the macromolecule, the electron cloud density of the nitrogen atom on the amido group is obviously reduced through the double bond conjugation of the benzene ring and the conjugation system of the benzene ring, the composite material has outstanding heat resistance and flame resistance, and the long-term use temperature is 250 ℃. Experiments prove that the polysulfonamide fiber has good heat resistance, high-temperature dimensional stability, chemical resistance, moisture absorption and dyeing performance. Polysulfonamide fiber materials are mostly applied to the fields of protective products, high-temperature filter materials, friction sealing materials, electric insulating materials and the like.
The aramid 1313 fiber is also called as: the composite fiber is prepared from m-phenylenediamine and isophthaloyl chloride through condensation polymerization and solution spinning, and has the characteristics of good air permeability, moisture permeability, high temperature resistance, flame retardance and most corrosion resistance.
The polyaryl oxadiazole fiber is POD for short and has the English name: poly-1,3,4-oxadiazole is a high-temperature-resistant aromatic heterocyclic polymer material with good thermal stability, chemical stability, electrical insulation property and the like. Have low flame shrinkage and provide additional thermal stability to spun yarns, and polyaryloxadiazole fibers refer to fibers composed of polymers containing oxadiazole units. A process for making polyaryloxadiazole fibers may be found in U.S. Pat. No. 4202962, which is commercially available under the name of Polythron.
The flame-retardant viscose fiber has good flame-retardant effect and the characteristic of being similar to natural cotton fiber, and the material has the advantages of enhancing the comfort performance of clothes and also has good natural antistatic effect. At present, the austria lanjing company, China Jilin chemical fiber, Tangshansanyou chemical industry, Shandong sea dragon and the like all have the fiber production.
The abrasion resistant flame retardant comfort fabric containing the staple fiber blend of the present invention can be made from staple yarns.
Abrasion resistant flame retardant comfort fabrics containing the staple fiber blend described herein include, but are not limited to, woven or knitted fabrics. General fabric design and construction are well known to those skilled in the art.
The woven fabric refers to a fabric formed by interlacing yarns in a radial direction or a weft direction, generally on a weaving machine, and filling or interlacing the yarns with each other to form any fabric structure (such as a plain weave, a satin weave, a basket weave, a satin weave, a twill weave, and the like). With plain and twill weaves being the most commonly used weaves in commerce and preferred in many embodiments.
By knitted fabric is meant a fabric that is typically formed by interconnecting loops of yarn using needles. In many cases, to make a knitted fabric, staple fibers are fed into a knitting machine that converts the yarn into a fabric. If desired, multiple warp threads or yarns, plied or not plied, may be provided to the knitting machine; it is conventional to simultaneously load a bundle of yarns or a bundle of plied yarns into a knitting machine and knit into a fabric, or directly into an article of clothing. Functional fibers are added to the knit fabric in some embodiments by feeding one fiber or fiber blend staple yarn simultaneously with one or more other staple or continuous filament yarns. The tightness of knitting can be adjusted to meet any particular need.
The invention adopts the flame-retardant vinylon fiber and the high-temperature resistant fiber for blending, and the prepared fabric has higher flame retardant property.
Surprisingly, in the invention, the polyaryl oxadiazole fiber is further blended and added on the basis of the flame-retardant vinylon fiber and the high-temperature resistant fiber, so that the synergistic effect is achieved, and the flame retardant property, the wear resistance, the air permeability and the moisture permeability of the product are further improved.
The wear-resistant flame-retardant comfortable fabric containing the short fiber blend has the characteristics of flame retardance and high temperature resistance, and simultaneously shows higher wearing comfort in the forms of high moisture permeability, high air permeability, high thermal resistance, high wear resistance and the like.
