Problems solved by technology

SOL It is a permanent flame retardant fiber, washable, safe and environmentally friendly, good flame retardant effect, small amount of smoke, no harmful gas, comfortable hand feeling, good wearing performance, etc. The disadvantage is that the strength is slightly lower than that of ordinary viscose fiber
[0004] The flame-retardant viscose fiber developed by Austrian Lenzing Company uses phosphorus-based flame retardants and adopts the production process of high-wet modulus viscose. The strength can reach 2.2-2.4cN / dtex, which is higher than ordinary domestic flame-retardant viscose fibers. 0.3~0.5cN / dtex, but its price is more than double that of domestic viscose fiber, and it will produce a lot of harmful smoke when burned

Embodiment 1

[0023] (1) Provide SOL FR and Lenzing FR short fibers of the same size of 2D×51mm at a weight ratio of 30:70, and mix the two fibers.

[0024] (2) Spinning process: picking cotton → mixing and opening → carding and beating hand opening → vibrating cotton box feeding → single beating hand forming coils → carding → primary drawing → secondary drawing → third drawing → roving → spun yarn → Winding → Packing.

[0025] (3) Weaving process: yarn steaming → warping → sizing → drawing in heald → weaving → inspection → grading → repairing → finished product; the warp and weft yarns are JC 9.7tex (twist 1950 twist / m) strong twisted yarn, and press 2S:2Z arrangement.

[0026] (4) Dyeing and finishing process: singeing → overflow scouring → mercerizing → overflow dyeing → loose drying → softening → pre-shrinking.

[0027] Using the above method, make 10 yarns, twill fabric, weight 200g / m 2 flame retardant fabric.

Embodiment 2

[0029] (1) Provide SOL FR and Lenzing FR staple fibers of the same size of 2D×51mm at a weight ratio of 40:60, and mix the two fibers.

[0030] Other steps are the same as in Example 1.

Embodiment 3

[0032] (1) Provide SOL FR and Lenzing FR short fibers and flame-retardant acrylic fibers of the same size of 2D×51mm in a weight ratio of 50:30:20, and mix the three fibers.

[0033] Other steps are the same as in Example 1.

Abstract

The invention discloses a yarn and a fabric made of organic silicon nitrogen system flame-retardant fiber and organophosphorus system flame-retardant fiber in a blending manner. As two or three types of flame-retardant fiber are blended, a synergistic flame retardancy function can be brought into play, the flame-retardancy effect is better than that of single fiber, meanwhile relatively good air and water vapor permeability and comfort can be provided for the fabric, the fuming amount of single phosphorus system adhesive fiber and the cost of a flame-retardant fabric can be greatly lowered, and relatively good cost performance can be achieved.

Description

technical field [0001] The present invention relates to the blending of fibers with different properties and related applications of the obtained products. Background technique [0002] Nowadays, flame-retardant fabrics have attracted more and more attention. The flame retardant function of textile materials is mainly obtained through two methods. One is to perform flame retardant finishing on ordinary fabrics. The first is to use high-temperature-resistant flame-retardant fibers such as aramid, polyimide, etc., and flame-retardant viscose fibers for blending to obtain a fabric with excellent flame-retardant properties, high strength, and taking into account wearing performance, comfortable, soft and breathable. Flame-retardant viscose fiber has become the preferred fiber material for flame-retardant protective clothing due to its good hygroscopicity, comfortable body feeling, low heat conduction, and low price.
