Flame-retardant acupuncture cotton and preparation method for same

Abstract

The invention relates to a preparation method for flame-retardant acupuncture cotton. The flame-retardant acupuncture cotton is prepared from 30 to 50 weight percent of aramid 1313 fiber and 70 to 50 weight percent of ES (ethylene-propylene side by side) fiber. A production process comprises procedures of material selection, opening, carding, lapping, needling, baking in a baking oven, roll cooling, forming and packaging, and the like, wherein the fibers are carded and formed at one time, and are directly lapped for pre-needling at one time through a one-time oscillating head, enter the baking oven for baking after down-stroke needling, upstroke needling, down-stroke needling and upstroke needling, and are roll-cooled and formed, the baking temperature is 150 to 190 DEG C, the baking time is 14 to 25 s, and the cooling temperature is -5 to 20 DEG C. The acupuncture cotton produced by the method has a high flame retardant property, and can be used as an automotive interior material, and meanwhile, the problem of molten drops of a flame-retardant material is effectively solved.

technical field

[0001] The invention relates to a preparation process of needle-punched cotton, in particular to a flame-retardant needle-punched cotton and a preparation method thereof. Background technique

[0002] The fire caused by the burning of fiber products has become one of the major disasters in modern society. The results of the investigation of fatal accidents caused by fire show that fires caused by interior decorations and textiles occupy the first place. The harmful gas released at the time is much more harmful to the human body than flame-retardant textiles. In recent years, with the improvement of people's consumption level, the per capita ownership of cars has also increased rapidly, the demand for automotive interior materials is also increasing day by day, and the consumption of interior materials is also huge. Automotive interior materials have relatively high safety indicators, and flame retardancy is one of the most important indicators in these indic...
