The spinning of common look requires between short-movie section and long segment to yarn with traditional gray yarn that color is wanted evenly, bar is done and will be got well, the style that fabric showed of its yarn then comparatively soft with restrain, while cloth cover effect is comparatively stiff.In the epoch of following the fashion with showing personality, people to yarn design also have higher requirement.
Summary of the invention
The spinning method for genuine that the purpose of this invention is to provide a kind of novel idea yarn.
This purpose of the present invention and other purpose will further embody and set forth by following detailed description and explanation.
The spinning method for genuine of idea yarn of the present invention comprises the basic fiber and the cotton of circulating, and wherein the cotton content in resultant yarn of circulation is no more than 40%, and described circulation cotton is card strips and/or blowing short flannel, between circulation cotton and the basic fiber color certain contrast will be arranged.
In the spinning method for genuine of idea yarn of the present invention, idea yarn raw material be mixed with dual mode, it is a kind of that to be that the circulation of certain color is cotton carry out mixing entirely with basic fiber; It is to adopt strip to mix that another kind of raw material mixes, and mixes on drawing frame.When spinning idea yarn, adopt blowing to lack the process of unit, with the amount of stable circulation cotton in raw material is formed as far as possible.
In the spinning method for genuine of idea yarn of the present invention, the technological design of carding machine comprises mote knife technology, rationally adjusts the installation of removable cover and amplify the cylinder cover plate and space.Described mote knife technology can be extractd mote knife or the mote knife height is put into extreme lower position for according to containing assorted situation in the comb and parallel cotton fibers prior to spinning feeding raw material, and the cotton of assurance circulation simultaneously is few to fall to even not falling.Being installed as according to design idea yarn of described reasonable adjustment removable cover to the requirement of cotton knot idea style, set the configuration of anti-dress of removable cover and normal mounting cover plate, if improve the density of product middle cotton node, can select removable cover not change and all anti-dress of removable cover, so that the mutual combing between cylinder and cover plate is produced a large amount of new cotton knot ideas with rubbing.Described amplification cylinder cover plate space transfer for spacing than normal look yarn in carding technology big by 100%～220%.
In the spinning method for genuine of idea yarn of the present invention, because the circulation cotton fiber length is little, in mixing in doubling step, adopt less roller gauge to improve the inherent quality of sliver, be beneficial to the back working procedure processing, for improving the intensity of rove and spun yarn, normal kind is big by 10% when its twist factor of design simultaneously.On winding process is provided with, compare, cotton knot and short slub etc. be provided with thresholding all amplify about 50% with traditional colour spinning, further its idea yarn that mixes entirely when winder to slubbing be provided with thresholding than the mixed idea yarn process setting of bar than sternly.。The comb and parallel cotton fibers prior to spinning machine of production idea yarn adopts FA201B carding machine and A186 series carding machine.
In the spinning method for genuine of idea yarn of the present invention, comprise that basic fiber and circulation are cotton, wherein basic fiber is conventional look spinning material, and the cotton selection of circulation comprises two kinds, a kind of cotton short flannel (being called for short the blowing short flannel) for the filtration of blowing secondary filter dirt that circulates, another kind is the accessory substance card strips on the carding machine.In the raw material configuration, select blowing short flannel and card strips, main cause is that it has a large amount of cotton knots, these cotton knots be a bit primary colors, some is cotton knot painted, that some is multiple color, according to circulation cotton will and basic fiber between certain color contrast is arranged, can according to circumstances carry out the processing of color, to reach the requirement of product design to the cotton of circulating.Circulate cotton content and circulation is cotton bigger to the Fabric Style influence with basic fiber color contrast, and the cotton content that wherein circulates becomes color contrast between positive correlation, circulation cotton and basic fiber that the highlighting property of vision of cotton knot in the fabric " idea " is become positive correlation with the dense degree of cotton knot " idea " in the fabric.
In the spinning method for genuine of idea yarn of the present invention, its carding process mainly contains: 1. mote knife technology rationally is set, according to containing assorted situation in the comb and parallel cotton fibers prior to spinning feeding raw material, can extract mote knife or the mote knife height is put into extreme lower position, the cotton that guarantees simultaneously to circulate is lacked to fall to even not falling; 2. rationally adjust the mounting process of removable cover, according to designing the idea yarn to the requirement of cotton knot idea style, set the configuration of anti-dress of removable cover and normal mounting cover plate, further, if improve the density of product middle cotton node, can select removable cover not change and all anti-dress of removable cover, so that the mutual combing between cylinder and cover plate is produced a large amount of new cotton knot ideas with rubbing; 3. amplify cylinder and removable cover spaces, the card clothing interaction is to improve the main technology that fiber divides the comb degree between cylinder and removable cover, because the spinning of traditional look is provided with tighter on this technology in order to reduce cotton knot, the present invention is provided with in this technology and has adopted technology bigger than normal, and normal look yarn in carding technology is spaced and is transferred between big 100%～220%, less to the effect of cotton knot reduction like this, and also have certain combing degree between the fiber.
In the spinning method for genuine of idea yarn of the present invention, on raw material, adopted a large amount of circulation cottons, reduced the production cost that look spins enterprise like this, meet the demand for development of low-carbon environment-friendly.The fibre length of blowing short flannel and card strips is shorter in its circulation cotton, contains a large amount of cotton knots in the fiber.When the circulation cotton spins rove and spun yarn with basic fiber, then want grasp bigger than normal among the present invention in idea yarn rove and the technological design of spun yarn twist factor, bigger by about 10% than conventional variety.Further, in order to obtain the outstanding effect of idea yarn woven fabric middle cotton node, then between circulation cotton and the basic fiber color certain contrast to be arranged, can select the cotton color that circulates according to the color of basic fiber in the fabric, also can select the color of basic fiber according to the cotton color of circulation, the cloth cover idea style that the color contrast and the mode that sets off produce between different circulation cottons and basic fiber has certain difference, and some idea performance is comparatively indistinct, and some is comparatively outstanding and slightly mad.The circulation cotton that can design simultaneously many group different colours carries out mix spinning with basic fiber, has then obtained the style of different colours cotton knot idea on cloth cover.
Idea yarn style of the present invention has two kinds of comparatively outstanding styles, the realization of its two kinds of styles is the difference of raw material hybrid mode, the present invention has disclosed the cotton and basic interfibrous full technology of mixing that circulates on blowing, then adopt above-mentioned technology to spin, the cloth style of yarn woven fabric of must offering advice shows as: simple grain cotton knot idea distributes comparatively even on cloth cover, cotton knot is many to be occurred with circle, and cotton knot is inlayed on cloth cover better, has not had the crosspiece phenomenon; And adopt feedstock production to become different blowing laps, then distinguish combing, when drawing frame carries out the mixing of stock yard strip, short flannel is more in the circulation sliver like this, the regularity of its fiber is bad, when the drafting drawing-off, short flannel is owing to swum, then spun strip thickness joint is more, the difference that the uniformity of the cotton distribution on strip of circulation is mixed more entirely is a little, its mixed idea yarn woven fabric is compared the effect that crosspiece has been arranged in style with the full idea yarn that mixes, it is many that the probability that the effect of cotton knot idea occurs with elongated color dot mixes more entirely, and mostly these crosspieces are to cause owing to the short flannel slubbing on the strip.
On being provided with, winding process to do corresponding adjustment during with the inventive method production idea yarn, because the idea sliver is done and is compared poorly with normal yarn, can rationally set winding process according to the requirement of Fabric Style, compare with the traditional colour spinning, it is provided with thresholding to cotton knot and short slub etc. and all amplifies about 50%.
