Abstract

The present invention belongs to the field of weaving technology, and is especially method of producing knitted jute / cotton underwear fabric. The present invention discloses the technological process and technological parameters for producing knitted jute / cotton underwear fabric with soft hand feeling, less strength loss and wear comfort.

Description

Technical field: [0001] The invention belongs to the textile field, and relates to a processing method of jute / cotton knitted underwear fabric. Background technique: [0002] my country is rich in jute resources and is the third largest jute planting country in the world. For a long time, jute has been used to make sacks and packaging materials due to its rough and hard fibers. In recent years, due to the extensive application of chemical fiber and plastic products, the market of traditional jute products is shrinking day by day. But at the same time, hemp textiles and clothing are increasingly popular. Among hemp fibers, jute has higher moisture absorption and release performance and initial elastic modulus than ramie and flax, and its anti-mildew and antibacterial ability is also stronger among hemp fibers. If jute fiber can be widely used in the field of clothing , it has great practical significance for environmental protection, sustainable development and solving the...
