Problems solved by technology

Although the patent application scheme has the advantages of flame retardancy, arc resistance and wear resistance, but due to the addition of halogen-containing flame retardants during spinning, toxic and harmful gases will be released during combustion, which is detrimental to environmental protection and safety.
In addition, the use of nylon will cause the fabric to melt and drip when exposed to fire, which may cause secondary damage to the wearer.
[0007] Also as document D).CN102634908B discloses "oil-repellent, water-repellent, flame-retardant, anti-static, silicon-removing multi-functional fabric", the technical effects recorded in paragraphs 0012 to 0015 of the patent specification are essentially obtained by the 100D / 48FDTY The post-finishing of the base fabric woven by heavy-net polyester low-elastic flame-retardant yarns as fibers, such as silicon-removing finishing, oil- and water-repellent finishing, and baking, does not have a permanent flame-retardant effect.

Embodiment 1

[0027] figure 2 The organizational structure of the permanent flame-retardant multifunctional fabric shown is composed of figure 1 Shown in figure 2 Here, reference numeral 1 denotes warp yarns and weft yarns, and reference numeral 2 denotes antistatic filaments woven into the warp yarns.

[0028] The above reason figure 2 The preparation method of the permanent flame-retardant multifunctional fabric includes the following steps:

[0029] A) Raw material selection, select high-temperature resistant intrinsic flame-retardant fibers mixed with natural fibers as raw materials for warp and weft yarns, and select antistatic filaments used to weave the warp yarns in a spaced state, in this embodiment , The aforementioned high-temperature-resistant intrinsic flame-retardant fiber is a synthetic organic fiber, the synthetic organic fiber is aramid 1313, the mass percentage of aramid 1313 in the fabric is 40%, the aforementioned natural fiber is cotton fiber, the cotton fiber The perc...

Embodiment 2

[0033] A) Raw material selection, select high-temperature resistant intrinsic flame-retardant fibers mixed with regenerated fibers as the raw materials of warp and weft yarns, and select antistatic filaments to be woven into the warp yarns in a spaced state. In this embodiment The aforementioned high-temperature-resistant intrinsic flame-retardant fibers are synthetic organic fibers. The synthetic organic fibers are aramid 1313 and aramid 1414. Aramid 1313 accounts for 70% of the mass of the fabric. Aramid 1414 is used in the fabric. The mass percentage is 7%. The recycled fiber is a mixed fiber of viscose fiber and bamboo fiber, and the mass percentage in the fabric is 10% each. The antistatic filament is a metal substance added during the spinning process ( Metallic material such as copper sulfide) polyester filament; the polyester filament accounts for 3% of the mass percentage of the fabric;

[0034] B) For spinning, the mixed fiber of aramid 1313, spun fiber 1414, viscose fi...

Embodiment 3

[0037] A) Raw material selection, select high-temperature resistant intrinsic flame-retardant fibers mixed with natural fibers as raw materials for warp and weft yarns, and select antistatic filaments used to weave the warp yarns in a spaced state, in this embodiment The aforementioned high-temperature-resistant intrinsic flame-retardant fiber is a synthetic organic fiber. The synthetic organic fiber is aramid 1313, polyimide and polyphenylene sulfide. Among them: aramid 1313, polyimide and polyphenylene sulfide are in The mass percentages in the fabric are 40%, 5% and 10% respectively. Natural fiber is wool fiber, and the mass percentage of wool fiber in the fabric is 44%. Antistatic filament is added in the spinning process. Carbon black acrylic filament; the acrylic filament accounts for 1% by mass in the fabric;

[0038] B) For spinning, the mixed fiber obtained by step A) of aramid 1313 fiber, polyimide fiber, polyphenylene sulfide fiber, and wool fiber is mixed into a clear...

Abstract

A permanent flame-retardant multifunctional fabric and a preparation method thereof belong to the technical field of protective fabrics and their processing. Composed of interweaving warp and weft yarns, features: the raw materials used for warp and weft yarns are a mixture of high temperature resistant intrinsic flame retardant fibers and natural fibers, or a mixture of high temperature resistant intrinsic flame retardant fibers and regenerated cellulose fibers, high temperature resistant The essential flame-retardant fiber accounts for 40-90% of the fabric, natural fiber or regenerated cellulose fiber accounts for 8-58% of the fabric, and antistatic filaments are woven into the warp at intervals. It accounts for 1-3% in the fabric. It can make the fabric permanently maintain the ideal flame retardant properties, and will not decline due to the passage of time or the increase in the number of washings; it reflects good environmental protection, breathability and comfort when wearing; it is safe; it can guarantee excellent resistance to heat for a long time Static performance; simplifying the process, enabling the aforementioned technical effects of the fabric to be fully reflected.

Description

Technical field [0001] The invention belongs to the technical field of protective fabrics and processing thereof, and specifically relates to a permanent flame-retardant multifunctional fabric, and also relates to a preparation method of the permanent flame-retardant multifunctional fabric. Background technique [0002] With the continuous improvement of people's health awareness and safety awareness, the requirements for textile fabrics with protective functions have become increasingly stringent. In recent years, in industries such as petrochemicals, electric power, fire fighting, coal mining, oil refining, and medicine, clothing made of flame-retardant fabrics has generally been favored. [0003] Because the price of fiber with flame retardant properties is relatively expensive, the flame retardant effect of flame retardant fabrics in the prior art is mostly reflected by the post-finishing of the fabric, such as the use of padding baking method and immersion drying method. , Co...
