Abstract
The invention discloses a low-tension knitting method of high-count single-strand wool yarn knitted fabric and knitted goods thereof. The method adopts a fine-gauge circular knitting machine to knit single-strand high-count wool yarn thin type knitted goods and comprises the following steps of: enlarging the triangle gradients in loop coiling, loop linking and loop forming stages and simultaneously shortening the bottom plane width of a needle-pressing triangle, therefore, apart from obtaining yarns required by loop forming from a yarn carrier when descending, the knitting needle returns part of yarns back from an adjacent loop-formed old yarn loop. The knitted goods are produced by the method. By optimizing the triangular design in a knitting needle drive system, the invention relieves the effects of the knitting needle and other loop-forming machines on the gripped or contacted yarns, reduces the technical resistance of new and old yarn loops in loop coiling and loop forming stages and causes the wool yarn loops with rigidity larger than common yarns to complete loop-forming action relatively smoothly, thus realizing the complete of the knitting technology under low tension condition.

The specific embodiment
A kind of low-tension knitting method of high-count single-strand wool yarn knitted fabric, the raw material in the present embodiment are sub-thread high-n wool 72N/1, and high plane No. circular knitting machine is the braiding of the high plane No. of single face (28 plane No. and more than) circular knitting machine.Specifically may further comprise the steps:
Because wool yarn at lasso to the lopping stage lopping resistance bigger than general fiber because of the wool fibre good springiness bears, so the triangle that drives the knitting needle motion is carried out following improvement: strengthen lasso, Lian Quan, the triangle gradient in lopping stage, with control knitting needle descending motion and the time of stopping, reduce the quantity of yarn bending between knitting needle, with the rising (tension force with conventional 3-4G is compared, and descends about 20%) that reduces yarn tension; Shorten depressing cam base plane width simultaneously and (shorten 0.2 to 0.4cm.), to reduce the pin number of pressing simultaneously, make knitting needle when descending except obtain the required yarn of lopping from thread-carrier, and from a part of yarn of the old coil rollback of adjacent lopping, relaxing this stage peak tension occurs because of the required yarn consumption of lopping fast rise, reduce the broken yarn rate, adapt to the needs of low-tension braiding.
Above-mentioned improved basic principle is as follows:
Generally all take actively defeated line mode on modern times circle latitude machine, promptly line feeding device provides required yarn according to the constant linear velocity that presets to lopping.But loop-forming element is also non-constant in different lopping stage yarn requirements, but constantly change, this just causes yarn tension very big in each stage fluctuation of lopping.In fact, when needle latch hooks new coil decline and old coil string cover, be subjected to bigger resistance, especially for the wool yarn coil of good springiness, suffered resistance is greater than general yarn.Test proof, yarn are in the lasso stage, and constant defeated yarn mode can not in time satisfy this needs along with continuous decline of knitting needle, causes this stage yarn tension sharply to rise.A high wool yarn is also proved this point at lasso until a large amount of risings of end breakage rate that lopping finishes.Should illustrate that yarn tension is also relevant with lopping stage adjacent windings state.The present invention is by shifting a part of yarn from adjacent windings when new coil is realized lasso with knitting needle decline with old coil, relaxing this stage peak tension occurs because of the required yarn consumption of lopping fast rise, reduce the pin number of same time lasso, and when the design triangle, should suitably strengthen corresponding to the angle of inclination at this position of lasso stage is the same with the pressing stage.Shorten depressing cam base plane width (in the present embodiment, changing 1.2cm into) simultaneously,, relax tension fluctuation, knitting cycle is carried out smoothly to help the yarn rollback from the 1.5cm of routine.
According to traditional single face plaiting knitting, guarantee that by the tension force that strengthens veil (wool yarns) good plaiting appears effect, but adopt this technology to prop up wool yarn and cause the braiding difficulty, be not suitable for the braiding of high wool yarn single face plaiting spandex (spandex silk consumption generally is lower than a 5%) knit fabric low powerful height.The present invention controls knitting vertical carrying angle and cross level angle by regulating thread-carrier, and cooperate the speed that knitting needle descends and the position of old coil in the gradient in lasso stage according to triangle, make wool yarn (veil 1) and spandex silk (wire gauze 2) when the stage needle latch of remaining silent overturns, realize the conversion of wool yarn and spandex silk lapping position, thereby guarantee that wool yarn appears at fabric face, reach low-tension and finish plating-knitted technology.The relative position of knitting needle and veil 1, wire gauze 2 as shown in Figure 1, L1 is the syringe needle trajectory among the figure, L2 is the nozzle line, L3 is a needle latch tongue trace, some a ', b ', c ', d ', e ', f ' on the some a among the figure on the syringe needle trajectory L1, b, c, d, e, the corresponding needle latch tongue trace L3 of f difference.When knitting needle under the triangle effect, descend from the extreme higher position, the veil and the wire gauze of being drawn by feed carrier enter between needle point and the bearing pin in succession.When bearing pin is concordant with the nozzle line, needle latch upset under old coil promotes, rationally control the pad yarn horizontal and vertical position of veil 1 and wire gauze 2, and cooperate knitting needle decline to enter the time of pin mouth, just can realize smoothly that veil 1 and wire gauze 2 are in the mutual conversion in stage lapping position of remaining silent, the transition state of veil 1 and wire gauze 2 realizes that low-tension weaves wool plated fabric at high proportion as shown in Figure 2.
This mistake, the unwinding yarn process conditions have also been improved in the present embodiment, to help yarn with the smooth unwinding of knitting cycle, be specially: the input yarn storage device before by mechanical intermediate plate is replaced by the magnetic intermediate plate, carry and unwinding to stablize yarn, minimizing is carried the unwinding difficulty that causes at a high speed because of yarn, reaches control tension force, further reduces the purpose of broken end.Final the present invention can realize end breakage rate reducing to 5 times/by original 25-30 time/, and effect is remarkable.
Above-described embodiment only is used to illustrate technological thought of the present invention and characteristics, its purpose is to make those skilled in the art can understand content of the present invention and implements according to this, can not only limit claim of the present invention with present embodiment, be all equal variation or modifications of doing according to disclosed spirit, still drop in the claim of the present invention.
