Description

Ultrashort fine and soft fiber poly-fleece spinning equipment
Technical Field
The invention relates to the technical field of spinning, in particular to ultrashort fine and soft fiber poly-fleece spinning equipment.
Background
The processing technology of the ultrashort fine and soft fiber yarn mainly lies in the spinning production of short-length and low-strength fibers, in particular to functional green and environment-friendly fibers such as kapok, organic cotton and the like, because the length is short and the strength is low, the problem that the traditional ring spinning is difficult to spin independently exists, and the ultrashort fine and soft fiber spinning production and the product development and application of kapok, organic cotton, combed noil and the like are not well developed and applied all the time, the shortage of natural fiber tension is favorably solved, the full application of leftovers of the worsted combed noil and ultrashort fine and soft kapok of a wool spinning enterprise can be realized, the additional value of textiles is favorably improved, the international competitiveness of the Chinese textile industry is favorably improved, and the sustainable development of the enterprise is favorably realized. Is beneficial to promoting the development of the kapok planting industry in southwest areas, solves the problem of shortage of natural fiber tension, and has obvious economic benefit and social benefit. The product can be widely used in the fields of medium-high grade clothes such as knitted underwear, thermal underwear, sweaters, woven leisure coats, socks, bedding and the like, and home textile fabrics.
At present, market resources are increasingly tense, various ultrashort fine and soft fibers, particularly functional ultrashort fine and soft fibers, cannot be fully utilized by the market at present, even if the ultrashort fine and soft fibers are applied to long-flow processing of a cotton spinning system, the highest content of the ultrashort fine and soft fibers is only slightly improved, most ultrashort fine and soft fibers must become noil in the processes of opening picking, carding and combing, otherwise, the ultrashort fine and soft fibers cannot be smoothly drafted in the subsequent processes such as drawing, roving and spinning, and the technical difficulty of ultrashort fine and soft fiber yarn processing lies in short fiber length, poor fiber length unevenness and low fiber strength. At present, many textile scientific researchers improve the spinnability of the fiber by carrying out long-flow poly-fleece spinning technical transformation on each spinning process device, such as pretreatment on the superfine soft fiber; the opening and picking adopt a short flow, the space between the opening and the noil part is properly reduced, and the rotating speed of a beating part is reduced; raising the position of the cylinder on the cotton carding equipment, and technically reducing the speed of the licker-in; the drawing adopts the auto-leveling device, the additional friction force field is increased in the drafting zone, the roller gauge is reduced, the rubber roller pressurization is increased, and other measures are taken; the roving adopts a high-efficiency false twister, the roving twist coefficient is properly increased, the drafting gauge is reduced, and the cradle pressure is increased; the spun yarn properly reduces the speed of a spindle and a front roller, and adopts a new rubber ring and a rubber ring pin to actively reduce yarn hairiness. However, the poly-fleece spinning technology has the disadvantages of multiple steps, high cost and difficult process control, the content of ultra-short fine soft fibers can be increased, and the yarn quality indexes such as yarn evenness, hairiness, strength and the like are improved to a certain extent, but the ideal high-quality yarn with the ultra-short fine soft fibers and high blending ratio cannot be obtained. Therefore, the development of the efficient roller-free drafting poly-fleece spinning equipment has great application value, can bring great opportunity to the spinning enterprises which are changing and upgrading to the maximum, save the production cost, optimally utilize ultra-short fine and soft fibers such as kapok, noil, recycled regenerated cotton and the like, and can spin the poly-fleece spinning which integrates the advantages of compact spinning and rotor spinning into a whole.
