Permanent-flame-retardant multicomponent blended yarn, fabric, fabric making process and molten metal splashing resistant protection garment

Abstract

The invention discloses permanent-flame-retardant multicomponent blended yarn, fabric, a fabric making process and a molten metal splashing resistant protection garment and belongs to the technical field of protection garment fabric. The blended yarn comprises, by weight, 64-75% of Lenzig flame-retardant viscose fiber, 15-30% of aramid fiber, 1-5% of polyimide fiber and 5-8% of nylon fiber. Consumption of intrinsically flame-retardant fiber is lowered, and consumption of the flame-retardant viscose fiber is increased; by adding the polyimide fiber and the nylon fiber, strength of the fabric isimproved, and the fabric has excellent permanent flame retardance and metal molten splashing resistance; the fabric has the advantages of being high in strength, moisture permeability and color fastness, comfortable to wear, environment-friendly and basically degradable.

Description

technical field [0001] The invention relates to a technology in the field of clothing fabrics, in particular to a permanent flame-retardant multi-component blended yarn, fabric, fabric manufacturing process and molten metal splash-proof protective clothing. Background technique [0002] Protective clothing against molten metal splashes is mainly used in the welding industry and is a necessary personal protective equipment for welding (including fusion cutting) operations. During the welding process, splashed metal droplets, fiery slag, hot weldments, etc. will cause burns. Welding protective clothing must provide effective protection against the special environment of the welding process. The biggest hazard in the welding process is not the generation of open flames, but the impact of molten metal droplets. The latent heat released by the solidification of scattered molten metal droplets will penetrate into the skin through clothing, causing local severe burns. Therefore, ...

Problems solved by technology

The first category, which is also a relatively low-end category, is flame-retardant cotton fabrics. This type is processed by post-finishing technology and has a good fireproof effect. However, as the number of washings increases, the strength and flame retardancy of the fabric The performance will gradually decrease, and the fabric is thick, the yarn count is thick, the wearing comfort is poor, the dimensional stability is not good, and it contains formaldehyde, which will cause skin allergies after long-term contact. The air has a strong pungent smell, and excessive inhalation is harmful to the human body; the second category is aluminum film composite fabrics. Although the thermal radiation performance of aluminum film composite protective clothing made of this fabric is good, aluminum itself is not resistant to high temperatures. It cannot protect molten metal, and this kind of protective clothing also has the disadvantage of poor air permeability, so the protective function and comfort cannot meet the requirements; the third category, aramid fiber, wool fiber and flame-retardant viscose fiber blended Fabric, the fabric has good protection performance and excellent strength, but the itching of wool fiber leads to poor wearing performance, and there are more aramid fiber components, and the price of wool is rising day by day, the price of fabric is high, and the cost performance is low
