preparation example Construction

[0051] In the second aspect, the embodiment of the present application provides a method for preparing the high-strength flame-retardant yarn provided in the embodiment of the first aspect, comprising: covering the core filament with the outer covering fiber to obtain a single core-spun yarn. Among them, the type selection, composition and weight ratio of the core yarn and the outer fiber, as well as the specification, fineness, twist, twist direction, etc. of the yarn, all refer to the high-strength flame-retardant yarn provided by the embodiment of the first aspect. Let me repeat.

[0052] Exemplarily, the outer covering fiber is prepared by mixing raw materials, opening, cleaning, carding into tops, and then drawing.

[0053] In some optional embodiments, the outer covering fiber is produced by the following method: the raw material of the outer covering fiber is made into a wool top of 4-5g / 10m and then drawn.

[0054] Further optionally, the drawing process adopts the pr...

Embodiment 1

[0061] A durable fabric made from high tenacity flame retardant yarns woven on rapier looms and dyed. The durable fabric has a plain weave and a grammage of 190g / m 2 .

[0062] Among them, the high-strength flame-retardant yarn has a specification of 30s / 2 and a denier of 177D. The core yarn is polyester, the strength of the core yarn is 7cN / dtex, and the denier of the core yarn is 30D. The outer covering fiber is composed of 50wt% pyrophosphate flame retardant viscose, 38wt% silicon nitrogen flame retardant viscose and 12wt% polytetrafluoroethylene. The weight ratio of the core filament and the outer covering fiber is 20:80.

[0063] The preparation method of the high-strength flame-retardant yarn includes:

[0064] S1. Mix the raw materials of outsourcing fibers in proportion, open them loosely, and clear them, and then make 4.5g / 10m wool tops through one pass on the flat carding machine. Draw frame in 3 lanes to obtain outsourcing fibers.

[0065] S2. Feed the outsour...

Embodiment 2

[0067] A kind of durable fabric, its difference with embodiment 1 is that the grammage of this durable fabric is 160g / m 2 , the specification of the high-strength flame-retardant yarn is 34s / 2, the denier is 156D, and the denier of the core yarn is 20D.

Abstract

The invention belongs to the field of textiles and provides a high-strength flame-retardation yarn and a preparation method thereof and a durable fabric. The high-strength flame-retardation yarn comprises a core filament and coating fibers, the core filament is mainly one of a polybutylene terephthalate fiber, a polyterephthalic acid-1,4-hexamethylene dimethyl ester fiber and a polyethylene terephthalate fiber while the strength is 6cN / dtex or above, the coating fibers are prepared from flame-retardant viscose and polyvinyl fluoride, and polyvinyl fluoride is selected from one or two of polytetrafluoroethylene and polyvinylidene fluoride. The preparation method includes that the core filament is coated with the coating fibers to obtain a single-stranded core spun yarn. The durable fabric is made from the high-strength flame-retardation yarn by weaving. By the high-strength flame-retardation yarn, problems of poor flame retardation, proneness to adhesion of metal residues and pronenessto embrittlement, poor high-temperature resistance, low strength and the like in use are effectively improved; high cost performance is achieved, and industrial production is facilitated by adoption of existing equipment; the durable fabric is high in durability and widely applicable to work clothes in high-temperature operating environments.

Description

technical field [0001] The application relates to the field of textiles, in particular, to a high-strength flame-retardant yarn, a preparation method thereof and a durable fabric. Background technique [0002] Existing work clothes, the work clothes fabrics used in them usually have problems such as poor flame retardancy, easy sticking to metal slag, poor high temperature resistance or low strength. Sex is poor. Contents of the invention [0003] The purpose of this application is to provide a high-strength flame-retardant yarn, its preparation method and durable fabric. The high-strength flame-retardant yarn effectively improves the problems of poor flame retardancy, easy sticking to metal slag, poor high temperature resistance and low strength. , the durable cloth obtained by weaving the high-strength flame-retardant yarn has better durability. [0004] The embodiment of the application is realized like this: [0005] In the first aspect, the embodiment of the present...
