Dyed cotton spun-laced production process and product

Abstract

The invention is applied in the field of non-woven fabrics, and provides a dyed cotton spun-laced production process and a dyed cotton spun-laced product. The process comprises the following steps of: blowing, degreasing, bleaching, dyeing, primary drying, carding, lapping, spinning-lacing, secondary drying and finished product coiling. The dyed cotton spun-laced product obtained by the process has multiplayer dyed cotton fibers, and the dyed cotton fiber of each layer contains multiple colors and can also contain one color. Spinning-lacing and dyeing in the traditional dyed cotton spun-laced production process are changed into dyeing and spinning-lacing, only partial cotton fibers before spinning-lacing are dyed, then un-dyed cotton fibers and the dyed fibers are blended in different modes, and finally the cotton fibers of different colors are fully entwisted by the spinning-lacing treatment and the colors are distributed uniformly, so that the dyed cotton spun-laced products of different styles can be obtained, and meanwhile, the purpose of obtaining good dyeing effect with little dye is also fulfilled; and compared with the traditional process, the production cost is saved.

Description

technical field [0001] The invention belongs to the technical field of nonwoven fabrics, and in particular relates to a dyed cotton spunlace production process and product. Background technique [0002] Spunlace products generally use natural cotton as raw material, and use high-pressure water needles to spray cotton fiber webs to fully entangle the fibers in the fiber webs. It is widely used due to the advantages of sufficient raw materials, simple handling, softness, and good water absorption. At present, the production process of dyed cotton spunlace products is: cleaning - degreasing - bleaching - drying - carding - laying - spunlace - drying - dyeing - finished product coiling, in this production method, due to spunlace The cotton fibers are entangled together to initially form a spunlace product with lines. When dyeing it, it is necessary to dye the whole spunlace product, which requires more dyes and costs more. Contents of the invention [0003] The technical pro...

At present, the production process of dyed cotton spunlace products is: cleaning - degreasing - bleaching - drying - carding - laying - spunlace - drying - dyeing - finished product coiling, in this production method, due to spunlace The cotton fibers are entangled together to initially form a spunlace product with texture. When dyeing it, the whole spunlace product needs to be dyed, which requires more dyes and costs more.
