Description
Technical field
The invention belongs to the preparation field of ramie spinning, particularly a kind of method of combing cotton ramie spinning.
Background technology
Traditional ramie spinning work flow is: (degummed ramie) → softening → shredding → comb fiber crops → pre-also (2 road) → combing → grilling (4 road) → rove → spun yarn.Owing to there is a large amount of overlength, over-length fibre in ramee, and fibre length is seriously uneven, causes that traditional process of ramie spinning operation is assorted, long flow path, and wastage of material is serious, and yarn quality is not high.
At " ramie converter spinning processing method " (ZL200410016663.9), " a kind of ramie spinning processing method " (ZL200310108414.8), in the patents such as " roller needle plate composite stretch breaking and spinning equipment for ramee " (ZL200510110059.7), be proposed a kind of new ramie spinning method, i.e. converter spinning, its flow process is: (degummed ramie) → crush cutting → pre-also (1 ~ 2 road) → combing → grilling (4 road) → rove → spun yarn, this technology shredding in crush cutting operation replacement traditional handicraft and combing two procedures, the mechanical damage to fiber can be reduced, reduce numb grain, improve the Length Regularity of fiber, reduce the overlength in ramie bar, over-length fibre.
But on the one hand, what adopt due to it is degummed ramie crush cutting, serious owing to being mutually entangled with and being wound around between fibers parallel degree of the stretching difference of degummed ramie, fiber, cause its crush cutting load large, roller pressure volume is large, and machinery is easy to wear, and the runner of crush cutting bar, doubling are more, thus affect crush cutting operation and rear road spinning carry out smoothly, also have impact on yarn quality.On the other hand, road processing thereafter is also confined to utilize ramie spinning equipment to spin, but because ramie industry size is relatively little, equipment research and development fall behind, and hinder the further Innovation and development of ramie process technology and product.
At current spinning unit, the spinning line of the cotton fiber that length is short is the shortest, and the machine speed of each operation is also the fastest, and overall technology level is the highest, slow a lot of than cotton spinning of the speed of production of the fibers such as the fiber crops that length is longer, hair, thin,tough silk.Although from the angle of resultant yarn, fiber is longer, the brute force of its resultant yarn can be larger, and in fact, after fibre length acquires a certain degree, the increase of fibre length is just very limited to the contribution of brute force.In general, the average brute force of current yarn can meet the demands substantially, and user is that to pay close attention to the brute force of yarn irregular more.Therefore, ramie can be stretch-broken to the length of 30-50mm completely, cotton spinning apparatus is utilized to carry out spinning processing, this not only can improve versatility and the interchangeability of ramie spinning equipment and cotton spinning apparatus greatly, the equipment of textile industry advanced person and leading technology can also be utilized greatly to improve spinning speed and the output of ramie, namely utilize advanced cotton spinning platform, promote the development that ramie is spun.
In " a kind of ramie cotton spinning processing method and the equipment of use thereof " (ZL201110117290.4) patent, propose crush cutting bar degummed ramie crush cutting being become cotton length, then it spinned on cotton spinning apparatus, the technological process of its combing is: (degummed ramie) → softening → pre-crush cutting → crush cutting → in advance also → silver lap → combing → drafting (2 ~ 3 road) → rove → spun yarn.Thereafter road processing is no longer confined to ramie spinning equipment, but utilizes that output is high, the measured cotton spinning spinning equipment of matter.But because it directly adopts degummed ramie crush cutting, especially after shortening is spaced in crush cutting, the burden of its crush cutting is heavier than the crush cutting burden in above-mentioned patent, therefore higher roller pressure volume must be adopted, and this will cause mechanical wear to increase the weight of further, and the runner of crush cutting bar, doubling are also more, thus affect carrying out smoothly and ramie yarn yarn quality of crush cutting operation and the spinning of rear road.In addition, during ramie combed yarn in patent is produced, ramie bar after crush cutting will adopt cotton combing machine, on the one hand, cotton combing machine faller gills etc. are strong to thick, hard ramee adaptability, on the other hand, current cotton combing mainly processing length at the fiber of below 35mm, be difficult to effective processing to the fiber of 35-50mm length, these all will affect carrying out smoothly of its yarn quality and spinning process.
