Description

Antibacterial blended yarn with wood pulp fibers and production process thereof

Technical Field

The invention belongs to the technical field of novel spinning, and particularly relates to an antibacterial blended yarn with wood pulp fibers and a production process thereof.

Background

With the increasing awareness of environmental protection and health care, more and more people are paying attention to natural fibers, and cotton fibers are widely applied to the production of various textiles as the most common natural fibers. At present, yarns on the market come out endlessly, are different in material structure, and are widely applied to the living fields of weaving, rope making, thread making and the like. Xinjiang long staple cotton fiber is well known in the textile industry due to its softness and length, is known as a cotton top grade product by people, and has the advantages of less frequent combing, uniform and smooth evenness and high dyeability. However, the elasticity and the heat retention of the long stapled cotton fiber blended yarn on the market are not good, so that the woven fabric has the defects of poor heat retention effect and poor elasticity.

Most of synthetic fibers adopted in the prior art have strong water absorption and are easy to breed bacteria, and are particularly loved by pests such as cockroaches, ticks and the like, so that bacteria and dust are accumulated on the surface and inside of a fiber material, potential pollution is caused, and the synthetic fibers are unfavorable for human health and indoor environment.

In view of the above, there is a need to develop an antibacterial blended yarn with wood pulp fiber and a production process thereof.
