Abstract

The invention relates to novel parallel composite yarns and structures. A fabric manufactured by the novel parallel composite yarns has the characteristic of untwisted composite yarn fabrics, comprehensively overcomes the appearance quality defect of the fabric, and shows more remarkable product characteristic in the aspects of high grade and high cost performance of fabrics. The invention provides superior and matured products for the upgrade and update of the textile industry of China.

Description

technical field [0001] The invention relates to a yarn structure in the field of spinning. Specifically, it is an improved structure of untwisted yarn. Background technique [0002] The invention patent with the application date of February 26, 2002, the patent number ZL02100698.9, and the publication number CN1181233C discloses a twistless composite yarn and its technology, wherein the skeleton yarn in the twistless composite yarn (or filaments) and untwisted short fiber bundles are in a parallel state, and are bonded together by adhesives in parallel; and the core-spun yarn structure of the skeleton yarn is wrapped around the unique untwisted fiber, so that the corresponding The fabric has been comprehensively improved in terms of aesthetics, comfort and practicality. [0003] In the above prior art, the purpose of yarn twisting is to increase the strength of the yarn, especially for yarns spun from short fibers, it is necessary. In this way, under the specific quality ...
