New sun-proof light-resistant enhanced polypropylene fiber and recycled cotton blended yarn and preparation method thereof

Abstract

The invention discloses a new sun-proof light-resistant enhanced 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 goods, 15 to 17 parts of cotton yarn leftover bits and pieces, 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, 8 to 10 parts of carbonized coffee grounds, 5 to 7 parts of dispersible adhesive powder, 3 to 4 parts of gelatin and a moderate amount of water. According to the new sun-proof light-resistant enhanced polypropylene fiber and recycled cotton blended yarn disclosed by the invention, modified recycled cotton fibers containing the carbonized coffee grounds are added, so that the ultraviolet resistance of the fibers is improved; the blended yarn made by blending the modified recycled cotton fibers with nanometer titania modified polypropylene fibers has the advantages that the strength is higher, the sun-proof light resistance is enhanced, and not only are the cotton goods recycled to protect the environment but also the value of the recycled cotton fibers is improved, and the application range is broadened.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a novel blended yarn of sunscreen and light resistance reinforced polypropylene fiber and recycled cotton 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 limited r...

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
