Problems solved by technology

This technical solution has the following defects: although glass fiber can withstand high temperature, is non-combustible and anti-corrosion, glass fiber will cause allergies to some people and produce contact dermatitis. list
Although the use of glass fiber is avoided, the flame retardant effect is obtained by impregnating the flame retardant aqueous solution. The flame retardant covers the surface of the yarn and is not washable.

preparation example Construction

[0042] The preparation method of flame retardant finishing viscose fiber of the present invention is:

[0043] (1) In the production process of viscose fiber, after the viscose is made into cellulose filaments, the cellulose filaments are formed after passing through an acid coagulation bath on the spinning machine, and the cellulose filaments are washed 2 to 3 times with clean water ;

[0044] (2) Soak the cellulose tow treated in step (1) in a solution containing the flame retardant tris(2-ethylhexyl) phosphate, the bath ratio is 1:10, stir once every 30min, the flame retardant It is 10% of the weight of cellulose tow, the impregnation temperature is 50-60°C, and the impregnation time is 5h;

[0045] (3) The cellulose tow after impregnation is taken out from the solution, and dried at a temperature lower than 180° C. to obtain a flame-retardant finished viscose fiber.

[0046] In the above method, the flame retardant can also be tris (2-chloroethyl) phosphate, tris (2,3-di...

Embodiment 1

[0053] According to the fiber weight, weigh 90% of flame-retardant viscose fiber and 10% of flame-retardant polyester. The two fibers are cleaned and blended by conventional cotton spinning system equipment, and then spun into 16s by ring spinning frame as weaving and knitting. yarn.

Embodiment 2

[0055] According to the fiber weight, weigh 80% of flame-retardant viscose fiber and 20% of flame-retardant polyester, the two fibers are prepared by conventional cotton spinning system equipment to clean cotton blended sliver, and then spun into 21s by ring spinning frame as weaving and knitting yarn.

Abstract

The invention discloses a flame-retardant yarn. The flame-retardant yarn is made by blending a flame-retardant viscose fiber and at least one high-strength flame-retardant fiber; the high-strength flame-retardant fiber is a flame-retardant polyester or a flame-retardant finishing viscose fiber; and in the flame-retardant yarn, the weight percentage of the flame-retardant viscose fiber is 40% to 90%. The flame-retardant yarn disclosed by the invention makes full use of the excellent flame-retardant property of the flame-retardant viscose fiber, blends with other fibers with good strength and good spinnability, and adjusts the amount of raw materials to balance and avoid the shortcomings of each raw material and magnify the advantages of the raw materials, so that the flame-retardant property and strength of the yarn are optimized, and therefore, a yarn with high flame-retardancy, long-lasting flame-retardant effect, high strength and stretch, and wear resistance is woven. The fabric woven with the flame-retardant yarn disclosed by the invention has a good flame-retardant property, and the fabric can have better elasticity because of the strong strength of the yarn.

Description

technical field [0001] The invention belongs to the technical field of textiles, in particular to a flame-resistant yarn. Background technique [0002] High-strength flame-retardant fabrics are mainly used in home textiles, such as mattresses and pillowcases. On the one hand, flame-retardant fabrics can meet the requirements of flame-retardant standards, such as the US 16CFR1633 mattress flame-retardant standard. On the other hand the fabric has a higher fiber strength. In the prior art, flame-retardant fabrics are made by blending glass fibers and viscose fibers and soaking them in flame retardants. This technical solution has the following defects: although glass fiber can withstand high temperature, is non-combustible and anti-corrosion, glass fiber will cause allergies to some people and produce contact dermatitis. list. In addition, because the fiber is woven into a fabric and then soaked in a liquid containing a flame retardant, the fabric has a good flame retardan...
