Problems solved by technology

However, the use of air-jet spinning to produce hemp-containing yarns with a public count below 2000 is always a technical barrier, because the fine nozzles of air-jet spinning often prevent hemp fibers from entering, and some even enter the first nozzle. Spray the yarn from the second nozzle

Abstract

The present invention is blended yarn of fine denier modal fiber and hemp fiber and its jet spinning process. The blended yarn consists of fine denier modal fiber and hemp fiber in the ratio of 20-80 to 20-80, the fine denier modal fiber is short fiber of 1 d or below, and the hemp fiber is flax fiber or ramie fiber. The jet spinning producing process of the blended yarn includes the following steps: mixing fine denier modal fiber and hemp fiber and producing mixed sliver of 2.0-2.8 g / m; producing fine denier modal fiber in 100 % into roving of 2.4-3.2 g / 10m, feeding the mixed sliver and the roving in required ratio into the same nozzle of one jet spinning machine to form the blended yarn. The said technological process can produce blended yarn in the structure of hemp fiber coating fine denier modal fiber core homogeneously.

Description

technical field [0001] The patent of the present invention relates to the spinning process in textile engineering, which refers to the fine denier modal and hemp blended yarn and its air-jet spinning production process. Background technique [0002] At present, many products such as tencel / spun silk, tencel / wool / cashmere have been successfully produced by air-jet spinning, some of which are patent-applied products. However, the use of air-jet spinning to produce hemp-containing yarns with a public count below 2000 is always a technical barrier, because the fine nozzles of air-jet spinning often prevent hemp fibers from entering, and some even enter the first nozzle. The yarn is ejected from the second nozzle. In addition, hemp fiber, whether it is flax or ramie, because the cross-sectional diameter of the single fiber is relatively thick among natural spinnable materials, processing hemp fiber products with finer cotton spinning equipment is a key point in cotton spinning t...
