Problems solved by technology

[0003] Using mechanical methods, fibers can be obtained from waste textiles, but due to fiber aging and mechanical damage, fiber strength and length will be lost to varying degrees, resulting in a decrease in fiber spinnability, product performance and added value.

Abstract

The invention discloses a method of utilizing waste textiles to produce rhombic fancy yarn. The method includes: treating the waste textiles into a mono-fiber state to obtain recycled fiber; blendingthe recycled fiber with strong fiber to obtain rough yarn of 600-800Tex in linear density; taking the rough yarn as core yarn, and utilizing a fancy twister to wrap first functional filament and second functional filament onto the rough yarn to obtain the rhombic fancy yarn, wherein wrapping twist is 30-50 twist / 10cm. The method overcomes the technical prejudice of current recycled fiber application, and the recycled fiber is applied to prepare the rhombic fancy yarn for the first time through proper process step and parameter adjusting, so that reutilization of the waste textiles is realized,cost is low, product additional value is increased, and the rhombic fancy yarn obtained by taking low-grade recycled fiber as a raw material can be widely used for high-grade products like high-gradegarments and decorative textiles.

Description

technical field [0001] The invention relates to the field of recycling waste textiles, in particular to a method for producing rhombic fancy threads from waste textiles. Background technique [0002] Textiles are indispensable items in human life. With the increase of population and the improvement of people's quality of life, the quantity of textiles consumed by people is increasing year by year, and the disposal of a large amount of waste textiles has become a difficult problem. The incineration of waste textiles will cause air pollution, and the landfill treatment will have an impact on the ecological environment of the soil; and re-spinning or processing textiles into other industrial raw materials through chemical methods is a more thorough method of recycling, but recycling higher cost. Using mechanical methods, the fibers in waste textiles can be restored to their original state, and then applied to different fields according to fiber properties. This method has the...
