Abstract

The invention discloses a method for producing diamond-shaped fancy threads using waste textiles. The method comprises the following steps: treating the waste textiles into a single fiber state to obtain recycled fibers; blending the recycled fibers with strong fibers to obtain a linear density of A roving of 600-800Tex; using the roving as the core yarn, the first functional filament and the second functional filament are wrapped on the roving by a fancy twisting machine, and the wrapping twist is 30-50 twists / 10cm to obtain a diamond-shaped fancy Wire. The method overcomes the technical prejudice of the current application of recycled fibers, and applies the recycled fibers to the preparation of diamond-shaped fancy threads for the first time through appropriate process steps and parameter adjustment, which not only realizes the reuse of waste textiles, but also has low cost and improved product quality. Value-added, diamond-shaped fancy yarns obtained from low-grade recycled fibers can be widely used in high-end products such as high-end clothing and decorative textiles.

Description

technical field [0001] The invention relates to the field of recycling and utilization of waste textiles, in particular to a method for producing diamond-shaped fancy threads by using 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 number of textiles consumed by people increases year by year, and the disposal of a large number of waste textiles has become a difficult problem. The incineration of waste textiles will cause air pollution, and landfill treatment will have an impact on the ecological environment of the soil; and chemically treating textiles and re-spinning or processing them into other industrial raw materials 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 the fiber pro...
