Problems solved by technology

[0009] The purpose of the present invention is to overcome the deficiencies in the prior art, provide a corn fiber that can take advantage of the advantages of good luster, high strength, good elasticity, high modulus, and biodegradability, and make up for its low moisture absorption and poor spinnability. , no natural antibacterial properties, poor taking performance and other shortcomings, but also under the premise of maintaining the antibacterial, moisture absorption, breathable and cool advantages of hemp fiber, the high strength and good shape retention of corn fiber make up for the hemp fiber. The fiber has the disadvantages of poor drapability and poor shape retention, and can spin fine-gauge yarns, even extra-fine-gauge yarns below 10tex, which overcomes the problem that hemp fibers are difficult to spin fine-gauge yarns

Abstract

The invention discloses a blended spinning antibacterial composite yarn of corn fiber and regeneration hemp fiber and manufacturing method thereof, which relates to spinning technique. According to technique scheme provided by the invention, the antibacterial composite yarn includes 30-60 quotient of corn fiber and 40-70 quotient of regeneration hemp fiber. The manufacturing method includes steps: a) treating the corn fiber by scotching, combing and pre-combining; b) treating the regeneration hemp fiber by scotching, combing and pre-combining; c) treating the pre-combined corn fiber and regeneration hemp fiber by strip combining, roving, spun yarn, drum winding and obtaining the blended spinning antibacterial composite yarn. The invention combines excellent characters of high strength and good shape keeping property of corn fabric, recuperates defects of bad overhanging property and bad shape keeping property of hemp fiber and regeneration hemp fabric, and captures problem of that hemp fiber can not be spun to thin yarn.

Description

technical field [0001] The invention relates to an antibacterial composite yarn made by blending corn fiber and regenerated hemp fiber and discloses a production method of the composite yarn. Background technique [0002] The development of new biodegradable fibers for clothing fabrics or industrial textiles is one of the important topics in the development and research of textiles today. Corn fiber is a new type of environmentally friendly fiber developed by Cargill-Dow (CARGILL~DOW) Polymer Company and Japan Bell Spinning and other companies. The fiber is made of polylactic acid fiber extracted from corn starch, that is, PLA fiber, which is called corn fiber in our country. [0003] Corn fiber combines the advantages of natural fiber and chemical fiber. Its mechanical properties are between polyester and nylon, and its strength and modulus are lower than polyester fibers and higher than nylon. Therefore, corn fiber fabrics are soft to the touch, have silky luster and br...
