Abstract

The invention discloses a production method for chitin-cotton-blended knitted fabric for underwear. The production method includes the steps that lactococcus lactis, sphingomonas, bacillus coagulans and bacillus megatherium are prepared into complex microbial inoculants; 1.5D*38-mm chitosan fibers are put into a fermentation culture solution, the inoculants are introduced to carry out fermentation, the inoculum size is 1%, fermentation temperature ranges from 37 DEG C to 39 DEG C, culturing time ranges from 12 hours to 15 hours, 3% to 5% of chitin fibers and the balance cotton are prepared into blended yarns in proportion, the count of the blended yarns is 14.5 Tex, the twist of the blended yarns per 10 cm is 79.0, and then the materials are knitted into the fabric. According to the production method, the technology is simple, operation is easy, the modification effect is good, the antibacterial performance of the chitin-cotton-blended knitted fabric is greatly improved, and particularly the candida resistance is quite high; in addition, wrinkle resistance can be improved, the fabric is more luster accordingly, and the performance can not be reduced along with increasing of the number of washing times.

Description

technical field [0001] The invention relates to a chitin-cotton blended knitted fabric for underwear and a production process thereof, belonging to the field of fabric finishing. Background technique [0002] Chitin fiber is a natural antibacterial fiber, and its blended fabric with cotton fiber has the characteristics of firmness, no wrinkle or shrinkage, bright color, good sweat absorption, not easy to fade and excellent antibacterial properties. The antibacterial principle of chitin fiber is relatively complicated. At present, there are mainly the following two theories: first, amino cations in chitin macromolecules and anions such as sialyl phospholipids that constitute the microbial cell wall attract each other, and the result limits the degree of freedom of microorganisms. It hinders its metabolism and reproduction; the second low molecular weight can enter the microbial cells, preventing the replication of the microbial genetic code from DNA to RNA, thus hindering the...
