Abstract
The invention discloses a method for spinning segment color yarn by front area segmentation and a drawing mechanism. The method comprises the following steps of: drawing and feeding a group A and a group B of fiber whiskers of which the linear density tex is Ta and Tb by a rear fixed roller and a rear loose roller which are arranged on the same rear roller shaft into a rear drawing area respectively, and keeping the drawing multiples of the rear area constant and the same, wherein in a front drawing area, the two groups of fibers are different in feeding speed and drawing multiple, and variable in segmentation; outputting by a front roller, adsorbing the group A and the group B of the drawn fiber whiskers to a mesh ring which is sleeved on a negative pressure special-shaped pipe; guiding and conveying by the mesh ring; allowing the fibers to pass through a Y-shaped or V-shaped air groove on the surface of the negative pressure special-shaped pipe; gathering and combining under the air flow adsorption action at the Y-shaped or V-shaped groove; and outputting and twisting by a yarn guide rubber roller to form fine yarn of which combination of different lengths and component ratios or combination of different colors are distributed in the length direction of the yarn.
Description
Technical field
The invention belongs to spinning shaping manufacture field, relate to the color spun yarn method of a kind of fine spining machine proparea segmentation section, and the device that is applicable to resultant yarn method of the present invention.
Background technology
Section coloured yarn is a kind ofly to be the yarn that is interrupted distribution at yarn longitudinal length direction Yarn color.The section coloured yarn that at present existing production technology is produced, its color scheme, yarn texture exist than big-difference because of the method for its production and processing is different.
Through the section coloured yarn that reeled yarn or single thread section dyeing method are produced, the fiber in each section color of its section coloured yarn line basically all is with of the same colour, and the section coloured yarn color is stiff, is prone to heavy regular.
Adopt the blending of different colouring performance fibers, the section coloured yarn of the explained hereafter that dyes again, its color scheme kind is few, and effect is influenced greatly by process conditions, section color segmentation random distribution, uncontrollable, different production batch effect reproduction property are unstable.
Adopt the color color matching of the mixing in doubling step section of carrying out, its resultant yarn need pass through the drawing-off of rove operation, spinning process again, and the color length of section is longer usually, section color effect yarn that can not the production short segments.
Adopt three rollers, the four roller fine spining machines spinning section coloured yarn of conventional roller list motor drive; Its yarn texture is A, the B composite construction yarn of discontinuity; Promptly at length direction along heart yarn A; Inequality, unequal length ground looping decorative yarn fiber B, so its yarn is in the longitudinal direction, thickness has significant change.
Adopt coaxial pair of rear roller spinning section coloured yarn; Two groups of fiber segmentations, equivalent, inequality proportions make up resultant yarn; Its yarn texture appears basically and is interrupted, the A of inequality proportion, B composite construction, if will realize that two groups of fibers fast or during the conversion alternate with each other of shorter length, the proparea drafting multiple of general roller drafting mechanism is bigger; Between its two one-components length; The transition length that two groups of fibers are A, B composite construction is longer, can not be fast, the short distance exchange, and the accurately distribution of control section coloured silk on length.
Summary of the invention
One object of the present invention is to provide a kind of fine spining machine proparea segmentation section color spun yarn method, and the special number of line density is respectively T
