Abstract
The invention discloses a one-step combination and double-twisting method of large-difference filaments, which comprises the following steps of: respectively winding two chemical fiber filaments A, B with large performance difference on an unbinding bobbin of the same double-twisting machine; respectively unbinding the two filaments during double twisting; and combining and then carrying out double twisting on the filaments by using a tension device. The filaments processed in the method have the advantages of uniformity, good product quality, low end-breaking rate during processing and high production efficiency.
Description
Technical field
The present invention relates to the textile yarn manufacture field, be specifically related to a kind of big-difference long filament one the step and close, the double twisting method.
Background technology
Chemical-fibres filaments is one of the most frequently used raw material of textile industry.Along with development of technology, the chemical-fibres filaments of various performances constantly occurs.The existing unicity of raw material in the present textiles develops to multicomponent.How with the chemical-fibres filaments of various different performances and lump together use be enhance productivity, the key of product quality.One of method that adopts at present be with the long filament of different component earlier on equipment such as doubling and close; And then on the chemical fibre two-for-one twister, carry out double twisting; This kind method is because the also very difficult control of fashionable tension force; Cause at double twisting and move back when separating that differences such as shrinkage owing to raw material cause and the degree of tightness phenomenon that differs appears in plying, therefore high, the poor product quality of end breakage rate when double twisting, and complex procedures production efficiency is low.Two be to adopt like 201010272608.1 of Chinese patents to be called the manufacturing approach that discloses a kind of bicomponent filament yarn in the patent application of " manufacturing approach of the different contraction bicomponent filament yarn of terylene super fine "; Be earlier with super fine polyester FDY that selects for use and the super fine polyester POY network of on Networking winder, pooling capital, and then pass through the chemical fibre two-for-one twister and add and be twisted into desired strand.Long filament is earlier through network and close in the method, and then through two-for-one twister twisting, two procedures is independent, and because through after the network processing, form fiber at the nexus place entangled to each other, changed and the structure of plying, influences yarn qualities.
Summary of the invention
Technical problem to be solved by this invention be overcome deficiency of the prior art and step of the big-difference long filament that provides a kind of and save operation, accelerate working (machining) efficiency, reduce yarn breakage, improve the quality of products and close, the double twisting method; This method can directly be implemented on existing equipment; Need not special corollary equipment; Requirement to equipment is lower, the convenient popularization.
The technical scheme that the present invention solves the problems of the technologies described above employing is: one of this big-difference long filament goes on foot and closes, the double twisting method; It is characterized in that may further comprise the steps: 1) chemical-fibres filaments A that two kinds of performance differences is big and B are wound on same chemical fibre two-for-one twister respectively and move back the two sections of separating bobbin; 2) bobbin that is wound into is installed on the chemical fibre two-for-one twister; Draw two kinds of chemical-fibres filaments respectively and pass the tensioner on the two-for-one twister synchronously by the threading requirement of two-for-one twister; 3) by technological requirement set the two-for-one twister speed of a motor vehicle, the twist and sth. made by twisting to, obtain the product line of two components after the start processing.Two yarns that the present invention is bigger with performance difference are wound on one respectively and move back and separate on the bobbin; Draw yarn respectively; Draw the yarn plying and carry out double twisting then through tensioner; Reduced separately and the process of closing through the method, in double twisting, accomplish yarn and close, advantages such as end breakage rate is low, production efficiency is high, good product quality had.
In the step 1) of the present invention; The chemical fibre two-for-one twister moves back to separate on the length of bobbin direction and is divided into two uniformly, and chemical-fibres filaments A is wound on double twisting and moves back the upper semisection of separating bobbin, and chemical-fibres filaments B is wound on double twisting and moves back the lower semisection of separating bobbin; Every kind of chemical-fibres filaments all is wound into pineapple shape; Overlapping phenomenon can not appear between chemical-fibres filaments A and the chemical-fibres filaments B, and other coiling parameter is consistent during with chemical fibre monofilament double twisting such as cone angle of coiling form, yarn tension, pineapple shape bobbin etc.Coiling purpose that is divided into two and benefit are to adopt elder generation and close in order to realize that moving back respectively synchronously of big-difference chemical-fibres filaments separate, can not produce simultaneously, and moving back of occurring during back double twisting technology separated the degree of tightness phenomenon that differs.
Two-for-one twister of the present invention moves back to be separated the bobbin top and also is provided with a washer type tensioner; When arts demand adds the elasticity of heavy twist or raw material when good especially; Chemical-fibres filaments A and chemical-fibres filaments B be except moving back the steel-ball type tensioner of separating in the bobbin through passing two-for-one twister in the lump, moves back at two-for-one twister and separate the bobbin top upper gasket formula tensioner that also will pressurize.This washer type tensioner effect and purpose are to separate a relaxation that occurs for anti-stopping to be delivered to barrel inner, avoid silk thread to produce the kink phenomenon.
The speed of a motor vehicle in the step 3) of the present invention, the twist, sth. made by twisting are to setting according to technological requirement.
The chemical-fibres filaments A of two kinds of performance big-differences of the present invention is generally: low elastic polyester filament, and chemical-fibres filaments B is generally terylene fully drawn yarn, and it is big or elastic difference is big that big-difference long filament of the present invention is defined as line density difference.Problems such as this type of long filament differs bigger owing to the various aspects of performance parameter, and therefore the processing method according to routine can produce end breakage rate height, poor product quality, and production efficiency is low.
The present invention compared with prior art has the following advantages: process route is short, and using needed elder generation originally and close or the operation of network, can merge a step through method of the present invention and accomplish.Applied widely, can be adaptable across the various line style combinations of chemical-fibres filaments series products.Product quality is good, two component finished product yarns that the method for the invention processing makes, and fiberless mutual intersection entanglement phenomenon, the flower strand is clear, and bar makes a good job of.Owing to original several procedures are incorporated in one completion, so production efficiency increases substantially.
