Abstract
The present invention relates to a method for spinning three-in-one elastic yarn from wool, filament yarn and urethane elastic fibers. The present invention is characterized in that firstly, a filament yarn feeding unit and an urethane elastic fiber feeding unit are additionally installed on a spinning machine, and definite pre-drafting is carried out for the urethane elastic fibers; secondly, the urethane elastic fibers are positioned by yarn guiding holes and are fed in the position of a jaw opening of a front roller to pass through the middle of roving strips normally drafted, and the filament yarn is also directly fed to the position of the jaw opening of a front roller through the yarn guiding holes and keeps a definite distance with the roving strips. The filament yarn and the roving strips of which the centers are coated with the urethane elastic fibers are together twisted below the jaw opening to form a twisting triangular area and then are wound on a yarn cop to form the three-in-one elastic yarn from wool, filament yarn and urethane elastic fibers. The present invention has the advantages of low spinning cost, high yarn quality, simple production and low degree of difficulties.
Description
Technical field:
The present invention relates to a kind of spinning method of stretch yarn, especially relate to the spinning method of a kind of wool, long filament and the three-in-one stretch yarn of spandex.Belong to textile technology field.
Background technology:
Along with the raising of people's living standard, the requirement of wool spinning product is shifted to frivolous, comfort type from warming-type.Simultaneously, behind the 2000 Games, elastic fabric becomes the fashion focus.The year growth rate of market of whole world elastic fabric is about 10%, and the Asian-Pacific area is then up to 15%.The maximum characteristics of elastic fabric are to have elasticity, and are comfortable and easy to wear, and motion can be showed U.S. of body curve freely to greatest extent.Obtain such lining, the spinning ELASTANE YARNS is the key link.
Our common ELASTANE YARNS at present mainly contains following several form:
1, the feeding spandex is made match network spun core-spun yarn on fine spining machine.
2, on doubling winder, feed spandex, obtain the elastic force wrap yarn by twisting.
3, utilize wool yarn and bright and beautiful ammonia long filament and sth. made by twisting, obtain stretch yarn.
More than various forms of yarns pluses and minuses are respectively arranged:
The road need not and twists with the fingers after the 1st kind of form, directly can weave cotton cloth, and produces simply, obtain than high-count, must use ramuscule wool, cost height.If wash blending and do hair, be easy to generate more card nailing neps after then weaving.
The road needs and twists with the fingers after the 2nd kind of form, and doubling winder is had certain requirement, and spandex feeding device must be arranged, simultaneously, and spandex fracture and cause that yarn elastic force is irregular easily during twisting.
The 3rd kind of form is then owing to too high being restricted of bright and beautiful ammonia long filament price.And back road needs and twists with the fingers, and produces complexity, and processing is painstaking.
Summary of the invention:
The objective of the invention is to overcome above-mentioned deficiency, provide a kind of spinning cost low, yarn qualities is good, produces the spinning method of simple, that difficulty is little wool, long filament and the three-in-one stretch yarn of spandex.
The object of the present invention is achieved like this: a kind of wool, the spinning method of long filament and the three-in-one stretch yarn of spandex, be characterized in: at first, on fine spining machine, install a long filament feeding unit and a spandex feeding device additional, spandex gives certain preliminary draft, then, spandex is located by thread guide eyelet, feeding is in the middle of the front roller nip place process rove bar yarn of normal drawing-off, long filament also directly is fed into the front roller nip place by thread guide eyelet, but to maintain a certain distance with yarn, below jaw, long filament and tundish the yarn of spandex and are twisted together, form a twist triangle zone, be wound up into and just form wool on the spool, the three-in-one stretch yarn of long filament and spandex.
The present invention is by promptly plastic with the disposable merging of wool, long filament and three kinds of raw materials of spandex spinning, and it is again little to produce simple difficulty.And the weaving cost is low, and yarn qualities is good.
Description of drawings:
Fig. 1 is a three-in-one spinning schematic diagram of the present invention.
Fig. 2 is a three-in-one feeding unit schematic diagram of the present invention.
The specific embodiment:
One, resultant yarn mechanism
At first, ring throstle being done some transformations, mainly is to install a long filament feeding unit and a spandex feeding device additional.Spandex will give certain preliminary draft because of flexible, can realize by two unwinding rollers.Unwinding roller is connected to front roller by chain, and the adjusting sprocket wheel just can change the speed ratio with front roller, guarantees that the spandex elongation is uniform and stable.Spandex is by being installed on the thread guide eyelet location on the ring throstle, and feeding is in the middle of the fine spining machine front roller nip place process rove bar yarn of normal drawing-off.Also thread guide eyelet directly is fed into fine spining machine front roller nip place to long filament on the fine spining machine by being installed on, but will maintain a certain distance with yarn, generally about 12mm.Below jaw, long filament and tundish the yarn of spandex and are twisted together, form a twist triangle zone, are wound up into and just form the three-in-one stretch yarn of wool, long filament and spandex on the spool, as Fig. 1～2.
Two, produce lime light
1, begin to produce before, the position that adjust the spandex thread guide eyelet guarantees the centre of spandex feeding at the yarn of normal drawing-off.Otherwise spandex will be exposed, and can rupture because of friction in the production of back road, and final lining shrinks irregular and form fault on face.
2, during spun yarn spinner joint, must check whether the yarn on the spool includes spandex and long filament, as not have, could joint after drawing clearly.During joint, guarantee that spandex, long filament and wool yarn connect simultaneously.
3, during winder, because spandex is flexible, if use air splicer, when blowing loose thread open, spandex can not spliced because of elasticity bounces back into.Simultaneously, long filament is also sliding because of itself, and rigidity is not suitable for splicing greatly.Therefore, be suitable for first yarn steaming typing, use mechanical splicer during winder instead, guarantee that joint spandex, long filament and wool yarn all connect.
4, owing to contain spandex in the yarn, the yarn steaming temperature is unsuitable too high, generally should not be above 90 ℃.
Claims (2)
1, a kind of wool, the spinning method of long filament and the three-in-one stretch yarn of spandex, it is characterized in that: at first, install a long filament feeding unit and a spandex feeding device additional at fine spining machine, spandex gives certain preliminary draft, then, spandex is located by thread guide eyelet, feeding is in the middle of the front roller nip place process rove bar yarn of normal drawing-off, long filament also directly is fed into the front roller nip place by described thread guide eyelet, but maintain a certain distance with yarn, below jaw, long filament and tundish the yarn of spandex and are twisted together, form a twist triangle zone, be wound up into and just form wool on the spool, the three-in-one stretch yarn of long filament and spandex.
2, the spinning method of a kind of wool according to claim 1, long filament and the three-in-one stretch yarn of spandex is characterized in that the preliminary draft of spandex realizes that by two unwinding rollers unwinding roller is connected to front roller by chain.
