Description

A kind of high-strength Fanglun l414 long filament/flame-retardant cotton fiber blended yarn woven fabric and preparation method thereof
Technical field
The present invention relates to a kind of fabric lining and preparation method thereof, particularly relate to a kind of high-strength Fanglun l414 long filament/flame-retardant cotton fiber blended yarn woven fabric and preparation method thereof.
Background technology
The development of high-performance fiber is the symbol of modern fiber science progress, and be the technological innovation of traditional textile industry, the conversion to high-tech industry creates advantage, for mankind's growth in the living standard contributes.Functional fibre refers to except the physical and mechanical properties that general fiber has, and also has the tencel of certain specific function.
High strength Fanglun l414 fiber refers to that intensity is greater than the 20g/ dawn, stands in the long period chemical fibre that high temperature (such as more than 200 DEG C) still can keep its original physical and mechanical properties substantially.Not softening under high temperature, still to maintain General Mechanics character special fibre.This fibrid has following basic characteristics: 1. fusing point and softening point high; 2. fiber at high temperature dimensionally stable; 3. macromolecular structure not easily degrades (Long-Time Service temperature is more than 200 DEG C); 4. there is the performance such as good hydrolysis and chemically-resistant medicament; 5. fire-retardant.
High strength Fanglun l414 long filament can not be all-round fibre, and it has advantage in some performance, and in other respects may with regard to existing defects, and such as hygroscopicity is poor, electrostatic is strong.
Cotton fiber is natural fabric, have moisture absorption, softness, feature that taking is good, but cotton fiber does not have anti-flammability.
In order to improve a kind of limitation of fibrous material, the method of multiple fiber blend can be adopted, blending product is carried out by the fiber finding some suitable, each fiber properties is retained, several functions superposes, maximize favourable factors and minimize unfavourable ones, to adapt to the requirement of environment for use to material property, or perhaps widen the range of application of material.
The high-strength Fanglun l414 long filament/flame-retardant cotton fiber blended yarn woven fabric of the one prepared by the present invention, has the features such as high strength, fire-retardant, high temperature resistant, breathable moisture permeability is good, and electrostatic is little, and wearability is good.
Summary of the invention
For above shortcomings in prior art, the preparation method that one of technical problem to be solved by this invention provides a kind of high-strength Fanglun l414 long filament and cotton yarn blending to weave cotton cloth, wherein also comprises the flame treatment of cotton yarn.Two of technical problem to be solved by this invention provides a kind of fabric prepared by said method, and this fabric has high fracture strength, excellent fire resistance and good taking and comfortableness.
The present invention seeks to be achieved through the following technical solutions:
A preparation method for high-strength Fanglun l414 long filament/flame-retardant cotton fiber blended yarn woven fabric, comprises following steps:
(1) cotton yarn is immersed in fire resistant fluid infiltrate, dry, make retardant cotton;
(2) Fanglun 1414's long filament (be called for short kevlar long filament) is twisted line with adding after the retardant cotton Split Down of flame treatment, the twist is 280-350T/M, twist with the fingers and twist with the fingers to for Z, the percentage by weight of described Fanglun 1414's long filament and retardant cotton is 2: 3;
(3) weaved cotton cloth as warp and parallel by the line after twisting, warp count is 200-250 root/10cm, and weft count is 180-220 root/10cm.
Wherein, described fire resistant fluid is made up of following compositions in weight percentage: fire retardant FPK80023-8%, WA dispersant 0.1-0.5%, penetrating agent JFC 0.1-0.3%, surplus is water.
Described fire retardant FPK8002 main component is nitrogenous organophosphorus ester compound, can buy from He Te global group (Shenzhen) Co., Ltd.
Described dispersant WA is the high-effect dispersant of a kind of organic silicon type, discloses the preparation method of this dispersant WA, can buy from Shanghai auxiliary reagent factory in " dyestuff and dyeing " 03 phase in 1975 " synthesis of dispersant WA and application thereof ".
Described penetrating agent JFC, full name is fatty alcohol-polyoxyethylene ether, belongs to non-ionic surface active agent, can buy from Shanghai auxiliary reagent factory.
Fire-retardant step: clean cotton yarn is put into yarn dyeing machine, then the fire resistant fluid configured stirring adds, for making fire resistant fluid infiltrate equably in cotton fiber, relating to process and comprising and be not limited to infiltrate technique, process for stabilizing, crosslinking process.
Infiltration technique concrete steps of the present invention are: after cotton yarn infiltrates 15-45 minute in fire resistant fluid, rotate 1-10 minute with the rotating speed of 10-20 rev/min, then rotate 20-30 minute with the rotating speed of 50-70 rev/min, de-liquid 1-10 minute.
The object infiltrating technique makes fiber surface fully absorb fire retardant, reaches each fiber surface and all covered by uniform fire retardant.
The important indicator parameter infiltrated in technique is the upper liquid rate controlling fiber, and preferably result controls the 5-15% in fibre weight.
Another technological parameter infiltrated in technique is the speed of gyration of cylinder, and in whole impregnation process, speed of gyration is a progressively high process, and by the programme-control of variable-frequency motor, wherein the maximum speed of final stage determines the upper liquid rate of fiber.The linear velocity that preferably the highest speed of gyration produces is 100-200m/min, and according to solubility and the attached outstanding power of infiltrate, after ensureing de-liquid, the upper liquid rate of material can ensure the required value in 5-15% scope.
Drying process key element in aforementioned stable technique, can do together with cross-linking process step, can adopt oven drying, and preferably method adopts radio frequency to dry, energy-efficient.
First can carry out pre-treatment to cotton yarn before step (1) flame treatment, pre-treatment step comprises degreasing process, cleaning etc.Wherein, described yarn degreasing, the concrete steps of cleaning and condition can adopt the pre-treatment process of existing continuous yarn dyeing to complete in dye beck, and preferred pre-treating method is:
(1) prepare cotton yarn pretreatment liquid, pretreatment liquid is made up of following compositions in weight percentage: 2-4% biology enzyme, 10-15% hydrogen peroxide, surplus are water;
(2) at 40-70 DEG C, cotton yarn is immersed pretreatment liquid 40-60 minute;
(3) with after 40-95 DEG C of hot wash, radio frequency is dried.
Pretreatment liquid is preferably made up of following compositions in weight percentage: 3wt% biology enzyme, 13wt% hydrogen peroxide, and surplus is water.
Described biology enzyme is scutching cotton teacher 100T, and scutching cotton teacher 100T is made up of following compositions in weight percentage: pectase 78%, cellulase 13%, amylase 7%, protease 2%.
Raw material of the present invention and equipment all commercially or customization can obtain.
The present invention also provides a kind of high-strength Fanglun l414 long filament/flame-retardant cotton fiber blended yarn woven fabric, adopts the preparation method of above-mentioned high-strength Fanglun l414 long filament/flame-retardant cotton fiber blended yarn woven fabric to be prepared from.
Positive progressive effect of the present invention is: the fiber adopting difference in functionality, the fabric that blending weaves, and has high fracture strength, excellent fire resistance and good taking and comfortableness.The user demand of special occasions protective clothing can be met.
