Description
Technical field
The invention belongs to the Textile Engineering field, it relates to a kind of fluff reducing device that has friction fasciated tube.
Background technology
The filoplume of yarn is a problem of common concern in the spinning processing always.Filoplume too much not only has influence on the production efficiency of back road processing as operation such as woven, knitting, and has influence on the presentation quality even the serviceability of final products.For example, numb, woolen, often filoplume is more because its fiber is thick, hard, causes it to produce prodding and itching feeling when making underskirt, has had a strong impact on its wearability.The technical measures of existing minimizing filoplume are: (1) installs collector additional in the front draft zone of fine spining machine, though the method is simple, but because the collector that adds in draw zone has influenced the friction field in this district, thereby disturbed the motion of fiber in draw zone, caused the uniformity of resultant yarn to worsen; (2) adopt to gather and novel spinning unit such as spin, as Elite spinning unit of the Cormforspin spinning unit of Switzerland Rieter company, German Suessen company etc., these methods are obtaining effect preferably aspect the minimizing filoplume, according to its product information introduction, filoplume can reduce 20～30%, but its shortcoming is: mechanism's complexity, and the cost height causes retrofitting of used machine difficulty and not too economic; (3) Japanese Murata Machine Co., Ltd adopts nozzle as the filoplume device that reduces yarn, this nozzle utilization vertically is tangential on the spray orifice in the yarn road that yarn passes through, in the yarn road, produce the air-flow of rotation at a high speed, thus with filoplume by friction twisting looping to yarn, with the filoplume on the minimizing yarn; But also there are two very important defectives in this method, the one, in order to make the repiece behind the broken end convenient, have a groove that is parallel to the yarn road on the yarn road of this nozzle, like this, yarn in the surface side warp road is easily run out of the yarn road when high speed rotary, must be furnished with bigger tension force, on the other hand, the air-flow of high speed rotary also is easy to from then on overflow in the groove, thereby influences the stability of original airflow field in the yarn road; The 2nd, this nozzle only utilizes the revolution air-flow that the filoplume on the yarn is carried out the friction twisting looping, and when the fiber of forming yarn was thick, hard, during as the wool yarn and the dimity, the effect that filoplume reduces was very limited; (4) filoplume that reduces yarn also has other method as adopting revolving ring, increase the fineness of yarn channel, thereby to reach minimizing the friction of yarn is reduced filoplume, but the effect of these methods is very limited.
At the defective of above-mentioned prior art, the invention provides a kind of fluff reducing device that has friction fasciated tube that is used on fine spining machine or the bobbin winder.
The technical scheme of technical solution problem of the present invention is as follows:
A kind of minimizing filoplume device that has friction fasciated tube, it comprises nozzle 1, sealing ring 3,3 ', air inlet pipe 4, it is characterized in that also comprising that an end slides on the socket cover 51 and the other end is supported on that friction fasciated tube 2 on the nozzle 1 and an end are supported on the nozzle 1 and the other end slides over friction fasciated tube 2 ' on the sleeve 5, have the sleeve 5 of socket cover 51, it is supported on the frame by a side lower end.
Compared with prior art, advantage of the present invention is:
The present invention not only utilized swirling eddy and make filoplume looping on the yarn on the surface of yarn to reduce filoplume, especially further utilized the special role of the looping groove that has on the friction fasciated tube, make the moment of friction of yarn of the inwall of nozzle and high speed rotary obviously strengthen, thereby can make the filoplume looping on yarn, further reduce filoplume again, this is for thick, hard fiber, as the filoplume on the yarns such as fiber crops, hair reduce more brought obvious effects, the present invention also have simple in structure, easy to use, with low cost, help advantage such as retrofitting of used machine.
