Abstract
The invention relates to a durable flame-retardant cloth and a preparation method thereof, and belongs to the fields of textile materials and flame-retardant materials. The durable flame-retardant cloth is prepared from, by weight, 10%-50% of long-stapled cotton fiber, 20%-70% of nylon 6 fibers and 20%-70% of polyphosphamide fibers. The method comprises the steps that 1, the raw materials of the long-stapled cotton fiber, the nylon 6 fibers and the polyphosphamide fibers are taken to be soaked in an ammonium salt solution of nano-montmorillonite for 6-24 hours; 2, the soaked long-stapled cotton fiber, nylon 6 fibers and polyphosphamide fibers are put into a combing machine to be combed, evenly mixed through a mixing machine and then spun into warp yarns and weft yarns with the count ranging from 20 to 110; 3, a cloth material obtained in the step 2 is soaked in a polyphosphamide solution to be soaked, dried and washed until no residue exists. According to the method, the nano-montmorillonite is permeated into the interior of the fibers, and polyphosphamide coagulated on the cloth surface under the high-temperature condition forms a stable flame-retardant protecting layer.
Description
Technical field
The present invention relates to a kind of Durable fire-retardant cloth and preparation method thereof, belong to textile material and fire proofing field.
Project background
Workers In Hot Environment operating environment is severe, is necessary for it and provides fire retardant protective clothing.Fire retardant protective clothing, due to its Long-Time Service, not only requires higher lasting fire resistance, also will have good snugness of fit.Du pont company successfully have developed aromatic polyamide " Nomex " fiber in early days, and its heat resistance is very good, and limited oxygen index reaches 29, although its limited oxygen index is not very high, after it leaves burning things which may cause a fire disaster, and can self-extinguish and do not produce molten drop; Aromatic polyamide " Apyil " fiber that " Terjinconex " of Di Ren company of Japan, You Nijika company successfully develop, its limited oxygen index can reach 29% ~ 32%; Amoco Corp. of the U.S. disclosed a kind of daiamid composition in 1999, can flame retardant effect be reached and there is good anti-performance and the incoagulable patent of invention of dripping, Solutia Corp also discloses fiber prepared by the flame-retardant polymer about polymer-bound non-halogen, fabric has anti-flammability.Other is as spandex fibre cloth, acrylic fiber cloth, polyacrylic and polyester fiber cloth, fire resistant viscose acetal fibre cloth, flame-resistant terylene cloth etc., and this fibrid all also exists meets fiery melting drippage, causes skin scald, can not reach the effect of fire safety.Adopt the cloth that flame-retarding blended fibre is woven into, realize flame resistant woven processing method, high-performance fiber and cotton carry out blending or to carry out blending with fire-retardant chemical fibre and prepare fire retardant with cotton and mainly contain through flame-retardant after-finishing process series products: acrylic fibers/Nomex, cotton/Nomex, cotton/Kevlar/Nomex, spandex/fire-retardant viscose, dacron cotton/terylene/nylon cloth prepares flame retardant fabric through Final finishing; Having Tetrakis hydroxymethyl phosphonium chloride to soak to cotton fiber is fire-retardant a long time ago, make cotton fiber have certain anti-flaming function, but feel is poor, water-wash resistance is poor, all loses anti-flaming function after generally washing 5 ~ 8 times; Fire retardant is normally added surface by the fire-retardant of chemical fibre, and this technology only can realize coming to the surface fire-retardant, and its product is a lot; For making nylon 6 fire-retardant, a kind of phosphonium flame retardant adds in PA6 by Beijing Institute of Technology Liu Ji equality, adopts melt spinning method, its addition is 2% ~ 6%, and PA6 can be made fire-retardant, and it is water-fastness to permanent, but the fibrous mechanical property that this method obtains is poor, there is serious melting drippage; Studied again a kind of polymeric phosphorus-containing flame retardant afterwards to mix with nano imvite, add in monomer, polymerization obtains flame-retardant anti-dropping PA6 fiber, melt spinning obtains the fiber of 3.1d and 3.5CN/tex, can reach permanent fire-retardant, the cloth char length be prepared into thus is 155.2mm, substantially remains unchanged after washing 50 times, substantially not melting drippage; In addition, professor Xia Yanzhi also studies the fire resistant viscose acetal fibre of hand feel performance excellence, at home industrialization; Professor Wang Yuzhong has also carried out extensive research to chemical fibre is fire-retardant, also has some to achieve industrialization.By cotton and polyster fibre, aramid fiber by blending, can practical function variation, not only can reduce product price, the diversity of snugness of fit and color can also be improved.Along with the development of textile technology, the development of flame retardant textiles develops to blending field gradually.Cotton/blend polyester Final finishing and cotton/aramid fiber blending become the main method preparing flame retardant textiles.But traditional blending hindlimb unload uses fire retardant mostly to be low molecular compound, in Long-Time Service poor durability, the shortcomings such as fire resistance significantly declines, service life is short, resistance to elevated temperatures is poor and intensity is low after ubiquity washing, are difficult to use as high-grade flame retardant products.Therefore, the aggretion type flame retardant treating agent that useful life longevity is good, good with cloth compatibility effectively can improve the quality of flame retardant fabric.
Low for flame retardant fabric heating temperature, the highest refractory temperature can only reach 260 DEG C, and produces the difficult problems such as melting drippage.The present invention is then completely different from these technical methods above-mentioned, both original single fire-retardant deficiency had been overcome, reach and drip without melting, achieve again the characteristic of heatproof, also unusual on the weaving method of cloth, adopt the T-shaped weave of 3 × 3, be woven into the fire-resistance cloth of ability 260 ~ 280 DEG C of high temperature, density reaches 200 ~ 360g/m
2, cloth char length is 92.6mm ~ 135.7mm (after washing for 50 times), and intensity is high-comfort good.
Summary of the invention
The object of the invention is can only reach 260 DEG C to solve low, the highest refractory temperature of flame retardant fabric heating temperature existed in traditional blending fire retardant and after-finishing flame resistant technique, and produce the difficult problems such as melting drippage, propose a kind of Durable fire-retardant cloth and preparation method thereof.
Core content of the present invention selects long-staple cotton fiber and nylon fiber to soak post-drying in nano imvite, the raw material after immersion and poly-phosphamide fibers mixture evenly spinned, then be made into cloth; The poly-phosphamide solution impregnation of cloth, dry after being washed to noresidue, reach the effect of permanent fire retardant.
The object of the invention is to be achieved through the following technical solutions.
