Description
Technical field
The present invention relates to a kind of fire resistance fibre field, specifically a kind of fire resistance fibre blended yarn, preparation method and fabric thereof and fabric.
Background technology
The development of science and technology is a double-edged sword, is offering convenience and while quality of life improvement, bring passive impact also to the existence of the mankind and working environment to human lives.Such as in some workplaces such as high temperature and electric welding, potential harm is brought to the living environment of inhabitation and operating personnel, shows that the spark of electric welding easily causes breakage or the burning of worker garments, bring hidden danger and infringement to health.So exploitation fire resistance fibre is very necessary.
Copolyamide fibre is the fire resistance fibre relatively commonly used in the market, the yarn that copolyamide fibre is formed has good anti-wear performance and excellent anti-flammability, but also there are some shortcomings in it, because copolyamide fibre ratio of elongation is higher, particularly the elongate fiber of meta-aramid fibers is larger, easily surprisingly in spinning process to extend, and its spinnability and antistatic property not ideal enough.Copolyamide fibre and the blended fiber processed of other fire resistance fibres, although overcome above-mentioned shortcoming to a certain extent, but, the fiber made hardens, not soft, utilize the fabric of this fiber process to wear uncomfortable, gas permeability is poor, long-term dress has wet stewing sense, and easily produces electrostatic.
Summary of the invention
It is good that the technical problem that the present invention mainly solves is to provide a kind of fire resistance, not easily produces electrostatic, and pliability improves, the Prospect for Flame Retardant Fiber Materials of good permeability.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is:
A kind of fire resistance fibre blended yarn, raw material comprises cortex and sandwich layer; Its mediopellis by weight content be 20-30% phenolic fibre, 20-25% flame-retardant acrylic fibre fiber, 30-40% copolyamide fibre, 20-30% antistatic synthetic fiber form.Sandwich layer by weight content be 10-20% wool fibre, 30-40% nylon fiber, 40-50% polyster fibre form.The weight content of cortex and sandwich layer is respectively 20-30% and 70-80%.
The preparation method of above-mentioned fire resistance fibre blended yarn, comprises the following steps:
(1) mixing and opening picking: first use that the antistatic agent solution of concentration 5-10% (weight) sprays phenolic fibre, flame-retardant acrylic fibre fiber carries out preliminary treatment, spray solution amount is the 12-15% of fibre weight, after packing, 24-48 hour stacked by vexed bag, and workshop humid control is about 75%; Then phenolic fibre, flame-retardant acrylic fibre fiber, copolyamide fibre, antistatic synthetic fiber are carried out raw material mixing; Then add dispersing agent for fibre to soak after 10-15 hour, then through high temperature drying, washing, dry process; Wool fibre, nylon fiber, polyster fibre are mixed, adds liquid flame retardant and soak 10-15 hour, then through high temperature drying, washing, dry process;
(2) comb and parallel cotton fibers prior to spinning becomes net and laminates, respectively Cortical fiber and core fibers being carded to network structure, is quantitatively 15-18g/5m in Cortical fiber carding process, the 0.15-0.18mm that spaces of sheet tin and cover plate, cylinder rotating speed is 310r/min, and licker-in rotating speed is 800 r/min.Be quantitatively 5-7g/5m in core fibers carding process, the 0.12-0.15mm that spaces of sheet tin and cover plate, cylinder rotating speed is 270r/min, and licker-in rotating speed is 650r/min.
Then Cortical fiber and core fibers are overlapped together;
(3) utilize mold heated shaping: mould adopts up and down heater separately, and cortex temperature controls at 50-60 DEG C, and core layer temperature controls at 60-70 DEG C;
(4) fiber crimp parcel: according to Cortical fiber outside, core fibers is curling 2-4 circle in the direction of inside, and core fibers is wrapped up completely;
(5) doubling: 2 fiber doublings, winding speed 310 m/min, adopts four downforce rod curve drawings on A272F type drawing frame three;
(6) twisting process: control yarn roller speed 200-220r/min, spindle speed 16000-18000r/min, the model RSS10/0-RSS 23/0 of steel traveler, the diameter of steel ring is 36-40mm.Twist yarn adopts the forward twist to be that 30-40 twists with the fingers/10 centimetres; During backtwisting, the reverse-winding twist is that 20-35 twists with the fingers/10 centimetres;
(7) rove, spun yarn, winder process is eventually passed.
Dispersing agent for fibre recited above is hydroxypropyl methylcellulose dispersant, and concentration is 20-30%, and consumption is the 5-10% of fiber consumption.
The application of fire resistance fibre blended yarn in sports goods, health care, fire prevention.
Fabric containing fire resistance fibre blended yarn.
The invention has the beneficial effects as follows:
The present invention adopts double layer fibre, comprise cortex and sandwich layer, cortex adopts phenolic fibre, flame-retardant acrylic fibre fiber, copolyamide fibre, antistatic synthetic fiber blended, the characteristic of various fiber can be given full play to, overcome Single Fiber Problems existing, fiber spinnability is improved, and flame retardant effect improves.Sandwich layer adopts wool fibre, nylon fiber, polyster fibre namely to reduce cost, turn improves the gas permeability of fiber.Carried out fire retardant immersion treatment to core fibers simultaneously, made sandwich layer also have fire retardancy, the flame retardant effect of whole fiber is very remarkable.
