Flame-retardant yarn and fabric, corresponding manufacturing method of flame-retardant yarn, corresponding after-finishing method of flame-retardant fabric, and garment

Abstract

The invention relates to a flame-retardant yarn, a flame-retardant fabric, a corresponding manufacturing method of the flame-retardant yarn, a corresponding after-finishing method of the flame-retardant fabric and a garment. The flame-retardant yarn comprises a first single-strand yarn and a second single-strand yarn which are used in cooperation with each other; the first single-strand yarn is a core-spun yarn, the core-spun yarn comprises core yarn and blended fiber yarn wrapping the outer surface of the core yarn, the core yarn is not prone to deformation, and the blended fiber yarn has the property that molten metal is prone to slipping off; and the second single-strand yarn contains pre-oxidized silk fiber, low-melting-point polyester fiber and flame-retardant polyester fiber. The flame-retardant fabric composed of the flame-retardant yarn is combined with a corresponding after-finishing method to be made into the garment, and flame-retardant protection can be effectively carried out. The flame-retardant yarn, the flame-retardant fabric, the corresponding manufacturing method of the flame-retardant yarn, the corresponding after-finishing method of the flame-retardant fabric and the garment have the characteristics of being convenient to produce, good in using effect and low in price, can be better applied to the field of production and manufacturing, and further provide guarantee for construction operation safety of operators.

Description

technical field [0001] The invention relates to the field of textile weaving, in particular to a flame-retardant yarn, a fabric, a corresponding production, finishing method and clothing. Background technique [0002] Metal smelters or welders generally need to work under conditions such as high temperature, molten metal splashing, and high heat radiation. During the working process, the temperature of liquid metal is extremely high, such as: the temperature of liquid aluminum can reach 800 degrees Celsius, and the temperature of molten steel can reach up to 1400 degrees Celsius, and the molten liquid metal is easy to splash, so it is necessary to pay attention to protective measures during the working process, such as wearing protective clothing correctly Otherwise, splashing molten metal will easily cause harm to the body. [0003] In order to avoid high temperature metals causing harm to the human body, there are specific requirements for the protective performance of pr...

AI Technical Summary

Problems solved by technology

[0008] 1) Flame-retardant cotton fabric is processed by post-finishing process, which has good fireproof effect, but the slipping effect of molten metal is average, and the residual strength of the fabric after slipping is low. With the increase of washing times, the strength of the fabric and The flame retardant 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. Long-term contact will cause skin allergies. In addition, ammonia fumigation is required in the whole process of flame retardant. Ammonia gas has a strong pungent smell, and excessive inhalation is harmful to the human body;

[0009] 2) Flame-retardant aluminum composite fabrics, aluminum film composite protective clothing have good anti-heat radiation performance, but this protective clothing has the disadvantages of poor air permeability and less slippage of molten metal than flame-retardant cotton fabrics, so the protective functionality and comfort Sex cannot meet the requirements;

[0011] 4) The flame-retardant protective fabric blended with wool fiber and flame-retardant viscose is a more common variety in the market. This blended fabric has excellent sliding performance when molten metal is splashed. When the metal is melted, the hairiness of the fiber shrinks sharply or is scalded, so it is not easy to catch the metal droplet, and thus has excellent protection performance, but the wool-containing fabric has poor washing shrinkage resistance

[0012] 5) Cow and sheepskin, the cost of cow and sheepskin protective clothing is relatively high, and it is thicker and less comfortable. It cannot be made into a complete clothing, and it lacks all-round protection for the human body

[0013] 6) Pre-oxidized silk fabric, pre-oxidized silk fiber has high temperature resistance, and has good metal melt slippage performance due to low fiber strength, but poor wearing performance, low strength, poor wear resistance, and lint loss after washing
