New non-hygroscopic wear-resisting anti-bacterial polypropylene fiber and recycled cotton blended yarn and preparation method thereof

Abstract

The invention discloses a new non-hygroscopic wear-resisting anti-bacterial polypropylene fiber and recycled cotton blended yarn, which is characterized by being prepared from the following raw materials in parts by weight: 40 to 43 parts of waste cotton fabrics, 15 to 17 parts of cotton yarn leftover bits and pieces, 1 to 2 parts of carnauba wax, 1 to 2 parts of polyoxyethylene fatty alcohol sodium sulfate, 5 to 7 parts of silicone acrylic emulsion, 3 to 4 parts of pre-gelatinized starch, 39 to 44 parts of polypropylene, 3 to 5 parts of nano-zinc oxide, 12 to 14 parts of liquid paraffin, 9 to 10 parts of nanometer titania, 1.5 to 2 parts of carboxymethylcellulose, 1 to 2 parts of glyceryl stearate and a moderate amount of water. According to the new non-hygroscopic wear-resisting anti-bacterial polypropylene fiber disclosed by the invention, after surface water proofing and sun-screening treatment is performed on recycled cotton fibers prepared from the waste cotton fabrics and the like, the waste cotton fabrics are blended with polypropylene fibers modified through sun-screening to form the yarn, and the prepared blended yarn is firm, wear-resisting, high in strength and light in specific gravity, and does not easily absorb moisture; the blended yarn can be used for manufacturing underwater clothing, such as swimsuits, or netting twines and the like; the quality of the recycled cotton fibers is promoted, and the application range of the recycled cotton is broadened.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a novel non-hygroscopic, wear-resistant and antibacterial polypropylene fiber regenerated cotton blended yarn and a preparation method thereof. Background technique [0002] With the rapid increase of the global population, all countries in the world will control the use of cultivated land, and the planting of cotton, hemp, and mulberry trees for sericulture will be restricted, and the traditional cotton textile raw materials will be subject to multiple constraints. Relevant data show that in 2010, the amount of leftover materials and other raw materials used in domestic recycled cotton yarns can reach about 3 million tons in total. It is estimated that 50% of the cotton is recycled yarn, and the cotton output per mu is 200 kg, which is equivalent to the output of more than 7 million mu of cotton fields. Regenerated yarn not only realizes the recycling of resources, saves limit...

AI Technical Summary

Problems solved by technology

Polypropylene fiber is light in weight, high in strength, good in elasticity, wear-resistant and corrosion-resistant, has electrical insulation and warmth retention properties, low moisture regain, low price, and good chemical resistance. It is widely used in the field of decorative fabrics, but due to The poor heat resistance and aging resistance of polypropylene fiber limit its application in the field of clothing
