Problems solved by technology

Seen from the effect of the embodiment, the product disclosed by the program has a higher arc resistance value and a moisture regain of more than 3%, which is relatively comfortable, but the above-mentioned two brands of flame-retardant rayon fibers are expensive, and are basically similar to meta-aromatic fibers. Polyamide (meta-aramid) is equal or more expensive, and the price of the finished product is higher

Embodiment 1

[0023] A comfortable arc-proof and flame-retardant blend, which is composed of meta-aramid, para-aramid, modified acrylic fiber, silicon nitrogen flame-retardant viscose and anti-static fiber; meta-aramid, para-aramid, denatured The sum of the mass of acrylic fiber and silicon-nitrogen flame-retardant viscose is recorded as A; the percentages of meta-aramid, para-aramid, modified acrylic fiber, and silicon-nitrogen flame-retardant viscose in A are: meta-aramid: 5 %; para-aramid: 5%; modacrylic: 65%; silicon nitrogen flame retardant viscose: 25%. The percentage of antistatic fiber in A is 1%.

Embodiment 2

[0025] A comfortable arc-proof and flame-retardant blend, which is composed of meta-aramid, para-aramid, modified acrylic fiber, silicon nitrogen flame-retardant viscose and anti-static fiber; meta-aramid, para-aramid, denatured The sum of the mass of acrylic fiber and silicon-nitrogen flame-retardant viscose is recorded as A; the percentages of meta-aramid, para-aramid, modified acrylic fiber, and silicon-nitrogen flame-retardant viscose in A are: meta-aramid: 30 %; Para-aramid fiber: 5%; Modacrylic fiber: 50%; Silicon nitrogen flame retardant viscose: 15%. The antistatic fiber accounts for 2% of A.

Embodiment 3

[0027] A comfortable arc-proof and flame-retardant blend, which is composed of meta-aramid, para-aramid, modified acrylic fiber, silicon nitrogen flame-retardant viscose and anti-static fiber; meta-aramid, para-aramid, denatured The sum of the mass of acrylic fiber and silicon-nitrogen flame-retardant viscose is recorded as A; the percentages of meta-aramid, para-aramid, modified acrylic fiber, and silicon-nitrogen flame-retardant viscose in A are: meta-aramid: 30 %; Para-aramid fiber: 5%; Modacrylic fiber: 40%; Silicon nitrogen flame retardant viscose: 25%.

Abstract

The invention discloses comfortable electric-arc-preventing flame retarding blends comprising aramid, modacrylic, and silicon nitride flame retardant viscose. The percentages of masses of three fibersto the total mass are: aramid fiber 10% to 60%; modacrylic 20% to 65%; silicon nitride flame retardant viscose 15% to 65%. the mass ratio of the silicon nitride flame retardant viscose to the modacrylic is 30% to 325%. Blends exist as fiber blends, yarns, fabrics, nonwovens, garments or the combination of the above. ASTM D6413-1999 is used for vertical burn test: the continued burn time is shorter than 2 seconds and the damaged length is no more than 6 inches.

Description

technical field [0001] The invention relates to the technical field of labor protection such as petrochemical, mining, metallurgy, steel, shipbuilding, electric power, etc. flame retardant protection and heat protection, in particular to a comfortable arc-proof flame retardant blend. Background technique [0002] Arc-proof clothing is mainly divided into two types, one is used in workplaces where arc discharge is particularly prone to occur, or the arc protective clothing required from head to toe is required for operations such as live closing or disconnecting electric switches; the other is in In a relatively large space, the energy level of arcs may be low, and the frequency of occurrence is low, so daily work clothes for arc protection are required. The design ideas of the two arc protection suits are quite different. The former mainly considers the performance of arc protection to be high, the protection must be strict, and the priority of wearing comfort and convenien...
