Problems solved by technology

[0002] The existing fabrics used to make towels are generally made by traditional spinning manufacturing process, which has problems such as complicated production process, low production efficiency, high processing cost and large consumables, and towels made of such fabrics are generally The towel is thicker and has more gaps in the plush, which makes it difficult to dry the towel after it is wet and is prone to bacteria and odors. In addition, scale is easy to deposit on the gap between the plush, making the towel harder and harder to wash. It is not suitable for sensitive skin.
[0003] Since non-woven fabrics have the advantages of light weight and breathability compared with woven fabrics, some existing towels are made of non-woven fabrics. Dyeing finishing and washing treatment of the cloth, the fabric surface effect of the non-woven fabric after the dyeing and finishing process is poor and the strength of the fabric surface is reduced, and the washing is easy to cause the non-woven fabric towel to fluff and fluff, which does not meet the product quality requirements

Abstract

The invention relates to the technical field of preparation and application of fabric, in particular to a preparation method and a product of colored cotton spunlaced nonwoven fabric. The preparationmethod includes following steps: step 1, making raw cotton fiber into a spinning cake, and putting the spinning cake into a bleaching vat for bleaching; step 2, putting the spinning cake after being bleached into a dyeing vat for dyeing; step 2, adding a color fixator to the cotton fiber after being dyed for color fixation, dewatering, and drying to obtain dyed cotton fiber; step 4, carding the dyed cotton fiber to be in a single fiber state; step 5, lapping the dyed cotton fiber after being carded to form a dyed cotton fiber net, and drafting the dyed cotton fiber net; step 6, spunlacing thedyed cotton fiber net through a high-pressure water curtain, and drying and winding the dyed cotton fiber net to obtain the colored cotton spunlaced nonwoven fabric. The colored cotton spunlaced nonwoven fabric has good fabric cover effect and high strength.
