Production process of ultra-low coarse yarns

Abstract

The invention discloses a production process of ultra-low coarse yarns. The production process includes: step 1, producing first coarse yarns with the fineness meeting the required count of finished products and having large coarse yarn twist; step 2, using the first coarse yarns as semi-finished products and feeding the first coarse yarns into a second coarse spinner which only performs twisting instead of drafting to achieve the effect of additional twisting; step 3, reasonably configuring the twist of the two coarse yarns, wherein the count of the first coarse yarns can be slightly higher than that of regular coarse yarns, and the traction of the second coarse spinner needs to be ensured to be smooth; and second coarse yarns are formed by twisting the first coarse yarns so as to ensure that the final twist of the yarns to reach the required twist standard of finished yarns. By means of the production process, a traditional coarse spinner can spin 2-count ultra-low coarse yarns.

Description

Technical field [0001] The invention relates to a yarn production process, in particular to a production process of ultra-low coarse yarn. Background technique [0002] In the classification of yarn counts, the commercial habit is called coarse yarn with less than 7 British counts. The commonly used machines in existing production include ring spinning machines and rotor spinning machines. Ring spinning machines are subject to special parts. Conditions are limited, especially the ring and traveler conditions. Ring spinning machines are generally difficult to produce coarse yarns below 6 British counts, and ultra-low coarse yarns below 3 British counts cannot be produced at all; Cup spinning machines are also restricted by their special conditions. Rotor spinning machines are generally difficult to produce coarse yarns below 4 British counts, and ultra-low coarse yarns below 3 British counts cannot be produced at all. [0003] However, there is currently a special yarn count-2 Brit...

Problems solved by technology

[0002] In the classification of the count yarn, the commercial custom is to call the coarse count yarn below 7 British counts. The commonly used machines in the existing production are ring spinning frame and rotor spinning machine. Due to the limitations of conditions, especially the conditions of steel rings and travellers, it is generally difficult for ring spinning machines to produce coarse yarns with a count of less than 6 pounds, and ultra-low coarse yarns with a count of less than 3 pounds cannot be produced at all; The cup spinning machine is also limited by its special conditions. The rotor spinning machine is generally difficult to produce the coarse count yarn below 4 pounds, and the ultra-low coarse count yarn below 3 pounds cannot be produced at all.

[0003] However, there is a special yarn count in the market - 2 British count ultra-low coarse yarn. This type of product and its strand products are mainly used for lamp twisting of alcohol lamps (furnaces) in scientific research and medical treatment. The fabric is mainly used for car interior decoration and medical abdominal belt and other products, which cannot be produced by using the above two yarn machines with the traditional production process
