Flame-proof treatment method for light and thin natural fiber material

Abstract

A flameproof treatment method of thin natural fiber material comprises that ultra-fine fiber fabric, poaching treatment or dyeing, low-temperature expansion flameproof treatment, baking crosslink, oxidization, neutralization, washing with water, checking final product, wherein the low-temperature immersion condition comprises 15-30Deg. C and 10-30s, the expansion treatment temperature is 35-60Deg. C for 20-40min, the baking crosslink temperature is 145-185Deg. C for 2-8min. Then the invention uses cleaning agent to process the ultra-fine flameproof fiber, while the cleaning agent is nanometer TiO2 or / and ZnO whose mass ratio is 1-12.0wt%, while the disperser is 0.2-1.5wt% as nanometer composite disperser to be treated in water solution.

Description

technical field [0001] The invention relates to a post-processing method of light and thin natural fiber materials, especially a flame-retardant and clean processing method. technical background [0002] The ecological performance of fiber materials has attracted the attention of the world, and Europe, America and my country have formulated strict ecological standards. Fiber materials with ecological properties that meet the requirements can ensure the health of users and promote the harmonious development of society. [0003] In industrial production, transportation and residential life, the use of fiber materials is increasing year by year. The fire losses and casualties caused by the flammability of fiber materials, especially ultra-thin, ultra-light, ultra-fine and ultra-soft fiber materials-ultramicrofibrous materials are shocking, and have been paid attention to by governments of all countries. In the United States, nearly 10,000 people are killed and killed by fire ...

AI Technical Summary

Problems solved by technology

[0004] In the 1970s, flame retardants such as THPC-APO, phosphorus nitrile resin, and ammonium dihydrogen phosphate were used to finish cotton fabrics in China, but the effect was still unsatisfactory.

The flame retardant processing of natural fiber materials and mixed materials of natural fibers and other fibers (including textiles) usually adopts two methods: padding method and padding ammonia fumigation method. These methods are effective for flame retardant processing of medium-thick fabrics, but Good results cannot be obtained for ultra-thin, ultra-light, ultra-fine, and ultra-soft fiber materials
