Production method for all-cotton spunlace non-woven fabric for medical health

The invention discloses a production method for all-cotton spunlace non-woven fabric for medical health. The production method includes the steps that blowing is conducted, wherein dust removing is conducted on pure-natural ginned cotton; primary carding is conducted, wherein fibers are combed to be orderly arranged, and impurities in raw materials are further removed; degreasing is conducted, wherein wax or grease on the cotton fibers is removed; bleaching is conducted; secondary carding is conducted, wherein the fibers are combed to be orderly arranged, and cotton knots may be generated in degreasing and bleaching are removed; net laying is conducted, wherein carded cotton nets are overlapped and spread in a reciprocating and staggered mode in the direction of the cotton fibers of the cotton nets; spunlacing is conducted, wherein high-pressure water flow is used for tangling the cotton nets; finished products are coiled. The two times of carding is conducted, greasing is conducted, then spunlacing is conducted, so that impurities and cotton knots are reduced to the maximum, the production cost is reduced, and raw materials and energy are saved. According to the production method, the raw material of the direct product is the pure-natural cotton so that the fabric is soft in texture, good in affinity with the skin, free of toxins, irritation and sensitization, good in water absorption, convenient to use and comfortable.

Viscose fiber and leecy fiber blended yarn and spinning technology thereof

The invention discloses a viscose fiber and leecy fiber blended yarn and a spinning technology thereof. The blended yarn comprises viscose fibers with the fiber content blending ratio of 60-70%, and leecy fibers with the fiber content blending ratio of 30-40%. The fibers are woven into the yarn through the spinning technology. Firstly, after the leecy fibers are subjected to opening and picking and cotton carding, the leecy fibers and the viscose fibers are mixed, then opening and picking and cotton carding are carried out, and the leecy fibers and the viscose fibers can be mixed to be uniform; due to the fact that the leecy fibers with the durable physical bacteriostasis function are added, the viscose fiber finished products can be prepared into the yarn with the antibacterial function directly through the following spinning technology, it is not needed to independently carry out antibacterial treatment on the viscose fiber finished products, the technology is simplified while the antibacterial effect is guaranteed, the production cost is reduced, fabric woven from the viscose fiber and leecy fiber blended yarn can be rapidly dyed, the colors are gorgeous, gradually varied and rich in layering sense after the fabric is colored, and multiple colors can be obtained through one time of dyeing.

Blended yarn of Shu elastic silk fibers and cotton fibers and spinning process thereof

The invention relates to a blended yarn of Shu elastic silk fibers and cotton fibers and a spinning process thereof. The blended yarn has the advantages of the Shu elastic silk fibers and cotton, is transcendental in size stability, natural, soft, high in air permeability and abrasive resistance, capable of being widely applied in the fields of cowboy costume, formal clothes, sport suit, knitted underwear and home textile, and broad in market prospect. According to the preparation process, the difficulties that the Shu elastic silk which serves as raw material fibers is high in elasticity and uneasy to reel separately and has too much crimps are overcome, the Shu elastic silk fibers and the cotton fibers are blended according to a blending proportion, and a cotton carding process, a roving process and a spun yarn process in the later period are completed. According to the process, the spun yarn process is adjusted, and the problem is solved that since the rebound resilience of the Shu elastic silk is high, coiling strips serving as raw materials are difficult to shape; a big-ration high-drafting process is achieved, the supply in the early period and the supply in the later period can be ensured, and the prepared blended yarns are high in single yarn intensity, small in variable coefficient and high in stability of fiber strength, show excellent rebound resilience, and meet demands of downstream manufacturing.
