Abstract

The invention discloses a banana bast fiber and ramie short spinning and blending fabric which is produced by weaving banana bast fibers and ramie which are used as raw materials. The ratio of the banana bast fibers to the ramie is 30-50:50-70, the warp density is 26n / inch, the weft density is 31n / inch, and the count is 4.5s-14s. The production method comprises the following steps of: pretreatingand curing the raw materials of the banana bast fibers and the ramie which are selected in a proportion, and then opening, slivering, spinning, warping, sizing, denting and weaving. In the invention,a new process flow is designed according to the performances of the two fibers, thereby enabling resultant yarns to combine the good properties of the two fibers. The fibers are very cool, and products has the characteristics of environmental protection, light weight, good lustre, high water absorbability, strong antibiotic property and degradability, and meanwhile, the defects of low count and poor spinnability of the banana bast fibers are eliminated; the fibers can be made into various fabrics of dresses, curtains, sheets and the like.

Description

Technical field: [0001] The invention relates to a blended fabric and a production method thereof, in particular to a short-spun blended fabric of banana bast fiber and ramie fiber and a production method thereof. Background technique: [0002] With the influence of the concept of ecological organization on a global scale, green consumption has become the dominant mode of textile consumption. As a new type of natural fiber derived from green plants, banana fiber has a series of advantages that other fibers cannot match, making it a very competitive new type of spring and summer clothing fabrics and high-breathability textile materials. Experts in the industry predict that banana fiber clothing fabrics will be hailed as "the most promising textile health fabrics in the 21st century". Banana bast fiber is a fiber made from banana stems by biological or / and chemical degumming process. It has the functions of light weight, good gloss, high water absorption, strong antibacterial...
