Abstract
The invention discloses a method for spinning section-color yarns and a drafting mechanism for spinning. At the rear drafting area of the drafting mechanism, leather rings are used for guiding and controlling yarns, namely a group of upper leather rings and a group of lower leather rings are used for controlling two groups of fiber fringes respectively, so for the rear drafting area of the drafting mechanism, the capacity of controlling free fibers is improved, when the drafting ratio at the rear area is changed greatly in sections, the stability of drafting of each sectional process is kept, and evenness and a sectional color effect of section-color resultant yarns are ensured. In the respect of product process design, the drafting ratio of the rear area is increased, and the transition length of the two groups of fibers between every two sections is shortened.
Description
Technical field
The invention belongs to spinning shaping manufacture field, relate to a kind of section coloured yarn spinning method, and the spinning, drawing mechanism that is applicable to spinning method of the present invention.
Background technology
Patent of invention waits in line density RING SPINNING section coloured yarn resultant yarn method and the device patent of invention for 201010636126.9 1 kinds and has proposed coaxial pair of laura structure; Promptly on the structural design of rear roller, adopt the rear roller axle, be set with the back kink roller that hard-wired back fixedly roller and kink are installed on it; Corresponding each ingot position; Back fixedly roller disposes with back kink roller in pairs, back kink roller and after fixedly the effective width of roller respectively to account for 1/2nd, two original rear roller work external diameters identical; To back fixedly roller and back kink roller, the epithelium posterius roll structure also is designed to be installed in two rollers that can rotate respectively on the same roller axle axle head corresponding to each.This invention is carried out partition running to the rotating speed of coaxial pair of roller, through speed, time, yarn are quantitatively controlled, keeps the fiber strip feed quantity of each rear roller control constantly constant, and realization waits the color spinning of line density section.
The drafter of this invention spinning apparatus; Thereafter plot structure is analogous to three conventional roller double belt drafting mechanisms; Three conventional roller double belt drafting mechanisms, because the fiber in first break draft district does not receive effective control, its drafting multiple can not be excessive on technique initialization; Generally be controlled at about 1: 1.05～1: 1.3 times, it is seriously irregular that excessive drafting multiple can cause the fiber strip bar to do.
It is to utilize the segmentation friction speed of the two rollers in back to rotate that the coaxial pair of roller section coloured silk spins drafter resultant yarn principle, to the alternately feeding of two groups of fiber strip segmentation friction speeds, make the feeding back fixedly roller with after the fiber strip of kink roller; Distinguish section in first break draft and obtain different drafting multiples; Form a section color effect, the color effect of its resultant yarn bar evenness, section, with the drawing-off of back zone have very big related owing to be alternate at the color back zone drafting multiple that spins two groups of fibers of fine spining machine epimere; And variation along with two groups of proportion of fibers; Two groups of fiber back zone drafting multiples are widely different, the technology controlling and process scope of normal head and shoulders above spinning, and it is irregular to produce bigger drawing-off; Especially divide the product of segment process for the short time, also can the section of causing color effect variation.
Summary of the invention
One object of the present invention is to provide a kind of section coloured yarn spinning method, with the fiber strip of two groups of different components combinations or different color combination, through the diplopore horn mouth; From two coaxial rear roller feedings, draw yarn to middle roller in the first break draft district by two groups of apron controls, draw two rear rollers of two groups of fiber strip feedings; By two servomotor transmissions, on the technology continuous spinning process is divided into several process sections respectively, adjacent process section; The combination of two rear roller rotating speeds is different, and two groups of fiber strips receive the drawing-off of different multiples in the first break draft district, and drafting multiple changes with the segmentation of technology; Through the middle roller collector, led into the front draft zone by middle roller, two groups of fiber strips converge in the front draft zone; Apron draws yarn control, exports, twists through front roller collector, front roller again through the proparea, forms to have on the length of yarn direction, to be distributed with the ring spun yarn that different length, the combination of different components ratio or different color make up, and it is characterized in that the first break draft district adopts two groups of aprons to draw the yarn control process; Respectively two groups of fiber strip elasticity are gripped with apron about in the of two groups; Be fed forward, two groups of fiber strips change under the situation greatly at first break draft district drafting multiple with speed feeding middle roller different and that segmentation changes; Enhancing is to the speed Control of free-fiber in the first break draft district; Keep the even of back area draft, be controlled to sliver and do, guarantee a section color effect.
A kind of section coloured yarn spinning method; The special number of line density is respectively two groups of fiber strips of first, second of T first, T second; Keep certain spacing to feed rear roller respectively, by the back fixedly roller and back kink roller traction feeding that are installed on the same rear roller axle, back fixedly roller apron surface linear speed is V
Gu, back kink roller apron surface linear speed is V
Live, in the first break draft district, the feeding speed of two groups of fiber rear rollers differs; Back zone drafting multiple differs; And section variable, two groups of fibers respectively by two groups in first break draft district up and down apron elasticity grip, carry, control by diplopore horn mouth behind the rear roller and the collector behind the middle roller; Two groups of fibers are in first break draft district keeping parallelism and certain intervals distance; Feed through middle roller, the front draft zone apron draws yarn control, front roller drawing-off output, twisting, forms to have the spun yarn that on the length of yarn direction, is distributed with different length, the combination of different components ratio or different color combination; During the spinning of section coloured silk; On the technology continuous spinning process is divided into several process sections; In each adjacent process section i and i+1, control two groups of fiber strips in the feeding speed of rear roller, promptly control feed quantity, change the content ratio of two groups of fibers in the resultant yarn; Change the structure and the appearance effect of product, the special number of two groups of line densities is respectively T
