Problems solved by technology

The lyocell fiber prepared by this method has strong antibacterial properties, the production process is simple, and the cost is low, but the antibacterial agent components used in it are relatively single, and long-term high-activity antibacterial effects cannot be achieved.
Therefore, the modification process of the antibacterial properties of lyocell fabrics needs to be further improved

Abstract

The invention relates to a preparation method of an antibacterial lyocell fabric. The fabric can be prepared by the following method: carrying out antibacterial finishing on a lyocell fabric in a finishing liquid containing polyhexamethylene biguanide hydrochloride and formaldehyde to obtain the antibacterial lyocell fabric. The initial bacteriostasis rate of the prepared antibacterial lyocell fabric to escherichia coli reaches 96% or above, after 20 times of washing, the antibacterial lyocell fabric still has high antibacterial performance to escherichia coli, and the bacteriostasis rate reaches 94% or above; the initial bacteriostasis rate of the antibacterial lyocell fabric to staphylococcus aureus reaches 98% or above, after the antibacterial lyocell fabric is washed 20 times, the antibacterial lyocell fabric still has high antibacterial performance to staphylococcus aureus, and the bacteriostasis rate reaches 94% or above.

Description

technical field [0001] The invention belongs to the technical field of fabric preparation, in particular to an antibacterial lyocell fabric and a preparation method thereof. Background technique [0002] With the vigorous development of synthetic fiber materials and their textile products, they have rapidly replaced traditional materials and are widely used in various sectors of the national economy such as industry, agriculture and military, and are closely related to people's daily life. However, because the human body sweats a lot, traditional textile fabrics and clothing are prone to odor and bacteria during use. Therefore, how to improve the antibacterial properties of textiles has become an urgent problem to be solved, so that the fabrics can not only reflect comfort and health, but also eliminate the odor of clothing and prevent the breeding of bacteria. [0003] Lyocell fabric is a fabric made of lyocell fiber. Lyocell fiber is called green fiber. Its performance is...
