Problems solved by technology

[0004] The existing spinning method of this kind of regenerated yarn mainly uses recycled cotton as the main body, which is more environmentally friendly. While recycling waste quilts, drug powder is added to play a physical therapy effect. However, when this regenerated yarn is made into clothing, due to the After combing and loosening, the fiber length becomes shorter, the strength decreases, and the anti-ultraviolet performance becomes worse, and the smell of the drug powder is easy to disappear after washing, and the physical therapy effect is not long-lasting

preparation example 1-3

[0036] In the preparation example 1-3, the coffee grounds are selected from the non-edible activated carbon coffee grounds sold by Shanghai Dandie Food Co., Ltd., the chitosan is selected from the chitosan sold by Henan Xihe Chemical Co., Ltd., and the bamboo fiber is selected from XH-0148. The article number sold from Hangzhou Jiekang Bamboo Fiber Products Co., Ltd. is the bamboo fiber of 002, and the nano-titanium dioxide colloid is selected from the model A212 nano-titanium dioxide colloid sold by Jingjiang Tonggao Chemical Co., Ltd.

preparation example 1

[0037] Preparation example 1: put 20kg of coffee grounds at 160°C to calcinate for 1 hour, take it out and mix it with 5kg of chitosan and 6kg of bamboo fiber, add 12kg of nano-titanium dioxide colloid, mix it evenly, dry it and grind it to a particle size of 10nm.

preparation example 2

[0038] Preparation example 2: 25kg of coffee grounds were calcined at 170°C for 1.5h, taken out, mixed evenly with 7kg of chitosan and 8kg of bamboo fiber, added 14kg of nano-titanium dioxide colloid, mixed evenly, dried and ground to a particle size of 15nm.

Abstract

The invention discloses regenerated cotton yarn and a preparation method thereof. The regenerated cotton yarn comprises, by weight, 45-50 parts of cotton yarn leftover leftovers, 30-40 parts of solidcotton, 25-35 parts of cotton, 10-15 parts of zirconia fiber, 5-10 parts of aramid staple fiber, 6-12 parts of medicine powder, 2-6 parts of pectin, 3-6 parts of waterborne polyurethane resin, 10-16 parts of nano zinc oxide, 10-16 parts of diatomite, 14-16 parts of coffee grounds, 50-65 parts of water and 20-30 parts of epoxy resin emulsion. The preparation method includes: S1, opening; S2, mixing; S3, cleaning; S4, carding; S5, drawing; S6, performing open-end spinning; S7, discharging yarn. The regenerated cotton yarn has the advantages of high ultraviolet resistance and lasting physiotherapy effect.

Description

technical field [0001] The invention relates to the field of textile technology, more specifically, it relates to a regenerated cotton yarn and a preparation method thereof. Background technique [0002] Regenerated cotton yarn refers to the fiber material produced by using some leftovers or waste silk produced in the process of spinning, weaving and garment processing as raw materials, and then reprocessed to produce yarn. The breaking strength of regenerated cotton yarn High, good wear resistance, small shrinkage, high heat resistance, high softness and elasticity. Regenerated cotton yarn not only realizes the recycling of resources, saves limited resources, but also solves the problem of scrap disposal, making a contribution to environmental governance. [0003] In the prior art, a Chinese invention patent application document with the application number CN201711144898.X discloses a spinning method for regenerated yarn, which includes the following steps: Cotton blending...
