Easily-dyed modified polypropylene fiber blended regenerating cotton yarn and preparation method thereof

Abstract

The present invention discloses an easily-dyed modified polypropylene fiber blended regenerating cotton yarn, which is characterized in that the easily-dyed modified polypropylene fiber blended regenerating cotton yarn is prepared from the following raw materials by weight: 40-43 parts of waste cotton fabric, 15-17 parts of cotton yarn leftover material, 5-7 parts of an aqueous polyurethane emulsion, 2-3 parts of dextrin, 39-44 parts of polypropylene, 2-4 parts of vinyl pyridine, 0.3-0.5 part of a titanic acid ester coupling agent TC-F, 3-5 parts of kaolin, 12-14 parts of liquid paraffin, 9-10 parts of nanometer titanium dioxide, 1.5-2 parts of carboxymethyl cellulose, and a proper amount of water. According to the present invention, the waste cotton fabric is used to modify to prepare the regenerating cotton fibers so as to reduce the production cost, then the polypropylene is molten and then is mixed with vinyl pyridine and other components, and spinning is performed to prepare the fibers having the active group, such that the dyeing is easy to perform, and the shortcomings of polypropylene fibers are improved; and the regenerating cotton fibers are blended with the modified polypropylene fibers, such that the prepared product has characteristics of easy coloring, high strength, wear resistance and corrosion resistance, and the quality of the regenerating cotton yarn is improved.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to an easily dyed modified polypropylene fiber blended regenerated cotton 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 limited resources, but also solves the ...

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 Polypropylene fiber has poor heat resistance and aging resistance, and is not easy to dye, which limits its application in the field of clothing
