Method and its device for ring spindle yarn multiple head spinning

Abstract

The technological process of ring spindle yarn multiple-headed spinning includes multiple-headed roving feeding of two or more pieces of roving via yarn finger, back roller and leather roller, multiple-headed stretching via at least one middle yarn finger, front roller pairs, leather roller and leather ring, leading out from the front rollers and leather roller, twisting in the twisting area, and further twisting and winding via the front yarn finger. For realizing the said technological process, the ring spinning machine has corresponding improved mechanism, a multiple-headed feeding and yarn fingering unit. The present invention has the advantages of obtaining spun yarn with improved structure, effectively reduced spinning hairiness, improved friction performance of spun yarn in later processing steps, improved spun yarn homogeneity, raised single yarn strength, etc.

Description

technical field [0001] The invention relates to the spun yarn spinning technology in the field of textile technology, in particular to a ring spinning spinning feeding method and a device thereof. Background technique [0002] Since the British Industrial Revolution, ring spinning in the textile industry has been a traditional process of feeding single rovings for hundreds of years. The yarn produced by traditional ring spinning has a so-called "spinning triangle" due to the lack of spinning mechanism. During the formation of spun yarn, the fibers outside the fiber bundles in the "spinning triangle" will be scattered in advance, resulting in many fibers that cannot be twisted into the yarn and protrude out of the yarn, resulting in yarn hairiness. At the same time, due to the spun yarn fed by single-head roving on the spinning frame, the fiber arrangement in the spun yarn structure tends to be relatively parallel, and the degree of entanglement between fibers is not strong....

Problems solved by technology

For example, for some fine-count pure wool and wool-chemical fiber blended yarns, the warp yarns are repeatedly subjected to various frictions during the weaving process, and the warp yarn hairiness and warp yarn pilling will become more and more serious, resulting in unclear shed opening and broken ends. 1. The hair particle phenomenon is very serious, which directly affects the weaving production efficiency and product quality. In severe cases, qualified products cannot be produced, and even weaving cannot be carried out normally.

In production practice, usually pure wool varieties can only be weaved with roving count warp single yarn products, but its weaving production efficiency is not high, while wool and chemical fiber blended warp yarn single yarn varieties, regardless of thick or fine yarn counts, are often regarded as The "forbidden zone" greatly restricts the production of high-grade light and thin fabrics that people love
