Abstract
A kind of method with the pure fabric of plain polypropylene nitrile fibrous woven device fabrication pre-oxidized polyacrylonitrile fiber, be with water-soluble fibre and pre-oxidized polyacrylonitrile fiber blending, be woven into the molten again soluble fiber that anhydrates behind the fabric, obtain virgin pp nitrile pre-oxidized fibers fabric at last.This method technology is simple, and the fabric cost is low, and yarn strength and weaving efficiency are higher, and the fabric flame resistance is good, and not on fire in naked light, fire endurance oxygen index (OI) can reach 48～60.This fabric can be used for the dustcoat of military equipments such as tank, artillery; Also can make the special fireproof clothes.It is the ideal fireproof textile material.
Description
The present invention relates to a kind of weaving techniques of the polyacrylonitrile fibre of anti-the combustion.Belong to the method for giving oxidized fiber fabric with the method processing virgin pp nitrile of blending.Being meant specifically that the fiber that adds in the blending process can dissolve after being made into fabric removes, and finally obtains the method that the virgin pp nitrile gives oxidized fiber fabric.
The weaving method of the known polyacrylonitrile fibre of anti-the combustion has: (1) adds chemical fire retardant, and this fabric can burn in naked light, only leaves just to have oneself behind the naked light and put out effect; The fire endurance oxygen index (OI) of this fabric is up to 28～30 simultaneously.(2) the virgin pp nitrile gives oxidized fibre phosphorus content height, property is crisp, need with 15～30% wool blendedly just have a spinnability, and wool need carry out flame treatment, the fire endurance oxygen index (OI) of the wool-blend fabric after the processing, compares with the fire endurance oxygen index (OI) that the virgin pp nitrile gives the oxidation fabric and to still have gap.
The objective of the invention is: a kind of method of giving oxidized fiber fabric with plain polypropylene nitrile fibrous woven device fabrication virgin pp nitrile is provided.
Realize that the technical scheme that the object of the invention adopted is: with polyacrylonitrile give oxidized fibre and water-soluble fibre bar by 60 to 40 to 85 than 15(weight ratio) mix, in relative humidity 50～70%, under the condition that temperature is 20～25 ℃ after the crush cutting slivering, through operations such as doubling, rove, spun yarn spinnings resultant yarn, again through winder, warping, weave, operation such as dissolving and be made into fabric; Drafting after-ripening bar weight can be 4.8～9.5g/m; The roving-drafting multiple can be 5～7 times, and the spinning-drafting multiple can be 15～17 times, and the twist can be controlled in 390～450 sth. made by twisting/rice, 8～55 public of scopes of can spinning, and fabric can be 260～310g/m
2
Advantage of the present invention and good effect are: textile technology is simple, need not to change existing acrylic Weaving device, and the fabric cost is low, and yarn strength is higher by 25～35% than wool blended; Higher more than 30% than the pure oxidized fibre that gives.Weaving efficiency is higher by 40～50% than wool blended, and is higher by 30～35% than the pure oxidized fibre that gives.The fabric flame resistance is good, and not on fire in naked light, the fire endurance oxygen index (OI) can reach 48～60.This fabric can be used for the dustcoat of military equipments such as tank, artillery, also can do the special fireproof clothes of military project, forest, public security.
Most preferred embodiment of the present invention is: with fibre fineness 1.5
(D) heavy 16g/m(of the hydrolysis vinylon fiber bar of the heavy 10g/m of bar, fibre length 90mm, regain 2.9% and bar or 8.8g/m), the polyacrylonitrile of regain 6.5% gives the oxidized fibre bar, giving the oxidized fibre bar by polyacrylonitrile is 75: 25 than hydrolysis vinylon fiber bar, under the condition of 20～25 ℃ of relative humidity 60～70%, temperature through B
