Spinning process of imitated airflow type slub yarn

Abstract

The invention relates to the technical field of spinning processes, in particular to a spinning process of an imitated airflow type slub yarn. The process comprises the following steps of S1, selecting raw materials of the imitated airflow type slub yarn, wherein the main cotton blending index is as follows, the technical grade is 3 .4 grade, the main body length is 27.8mm, the fineness is 6120 metric count, the breaking specific strength is 21.8, the short cashmere ratio is 12.7%, the impurity content is 2.3% and the moisture content is 7.5%; S2, selecting process equipment and process, and selecting (FA002-FA006C-FA104-FA022-FA106-FA141) open cleaning unit-FA201 carding machine-FA311 type draw frame-BD200SN type airflow spinning machine; S3, making a spinning yarn process, and drafting open cleaning process-carding process-parallel process-airflow type slub yarn spinning process. The process can produce the imitated airflow slub yarn with strong stereoscopic effect and various styles.

Description

technical field [0001] The invention relates to the technical field of spinning technology, in particular to a spinning technology of air-flow-like slub yarn. Background technique [0002] With the continuous improvement of people's living standards, the pursuit of clothing fabrics also tends to be fashionable, individual and diverse. As a fancy yarn with the fastest development and the most mature technology at present, slub yarn is widely used in both woven and knitted fabrics. Because of its unique style, it is more and more popular among people and has broad market prospects. The slub yarn device appeared in the 1980s and was only popularized in the 1990s. The early slub yarn device controlled the rotation of the roller through the attraction and disconnection of the electromagnetic clutch to achieve the purpose of spinning slub yarn.

Problems solved by technology

The slub yarn device appeared in the 1980s and was only popularized in the 1990s. The early slub yarn device controlled the rotation of the roller through the attraction and disconnection of the electromagnetic clutch to achieve the purpose of spinning slub yarn. The length of the slub, The thickness is not easy to control and the adjustment range is small. Since the electromagnetic clutch is frequently engaged in long-term continuous production, the failure rate is high and yarn damage is easy to occur.

With the continuous development of electronic technology, in the 1990s, a slub yarn device that independently controlled the speed of the spinning roller by a stepping motor and a programmable controller began to appear. This device input 5 sets of slub parameters, and automatically combined into 25 Group slubs for cyclical production, and cannot weave irregular slub yarns with random distribution in the true sense
