Abstract
The invention relates to a process for manufacturing polyester fiber filament by using a false twisting deformation elastic-adding machine, which is characterized in that raw material strand silk which is from a roller (1) passes through an inlet silk guide (2), then directly passes through a hot box(3) and is heated by the mode of non-contact heating, then moves to a turning silk guide (5), (or passes through a twisting machine 6), then passes through a two-roller (7) and reaches to a network jet nozzle (8) and is manufactured to obtain fully drawn yarn FDY (or shape preserving performances with high requirements such as profile degree, degree of hollowness and the like) polyester fiber filament, The process has the advantages of without altering the device, simple process adjustment and the like, and the switching of the two product processes is flexible and convenient, and the process efficiently extends the using range of the false twisting deformation elastic-adding machine and has obvious economic benefits.
Description
Technical field
The present invention relates to a kind of production method of polyester filament, specifically is a kind of technology of using false twisting distortion elasticizer to produce polyester filament.
Background technology
The terylene chemical-fibres filaments is very many a kind of garment material raw materials of using in the daily life.Its fabric biggest advantage is that wrinkle resistance and conformality are fine, is fit to make the overcoat clothes.But dacron is compared hygroscopicity with natural fabrics such as cottons, preserve moisture, gas permeability is relatively poor, wear the feeling of oppression and heat that has easily next to the shin, development along with society, the raising day by day of chemical fibre technology and people's living standard, the improvement of terylene dress ornament performance comfortable and easy to wear and the raising of visual sense of beauty thereof are particularly important, various functional forms, differentiated product constantly occurs, the functional embodiment of wherein most differentiations of product requires polyster fibre to have special-shaped preferably degree or degree of hollowness, and process will have guarantor's type effect preferably, can satisfy the functional demand of garment material.The flat traction machine of prior art, its structures shape heavy denier yarn short because of heating distance and time, it is irregular and insufficient to be heated, and is unfavorable for even stretching, product easily heat wet shrink irregular, fabric size instability, and feel is good inadequately.
False twisting distortion elasticizer only is used to produce stretch textured yarn usually, can't guarantee fidelity performances such as finished product degree of profile and degree of hollowness, and be difficult to produce the FDY product.Produce above-mentioned fullly drawn yarn (FDY) FDY or be used for the technology of the demanding polyster fibre long filaments of conformal performance such as degree of profile, degree of hollowness with it, in Chinese patent literature, do not have to find relevant or close report.
Summary of the invention
The technical issues that need to address of the present invention are to provide a kind of new technology, the polyster fibre long filament of the alternative flat traction machine production of use false twisting distortion elasticizer fullly drawn yarn (FDY) FDY.
Another technical problem that the present invention need solve is to provide another kind of new technology, the demanding polyster fibre long filaments of conformal performance such as use false twisting distortion elasticizer production degree of profile, degree of hollowness.
A kind of technology of using false twisting distortion elasticizer to produce polyester filament of the present invention, on false twisting distortion elasticizer, carry out, it is characterized in that from the raw material strand of a roller through the inlet thread guide, directly undertaken after the noncontact heating to turning to thread guide by a hot case, arrive the nozzle of interlace through two rollers again, advance two hot casees, the most laggard three rollers, oil tanker, coiling and molding product;
A described heater temperature is 80 ℃～120 ℃ (former technologies be generally 〉=180 ℃), and two heater temperatures are 120 ℃～200 ℃ (former technologies be generally 〉=160 ℃); Suitably reducing by two heater temperatures is in order to be more suitable for stretcher strain.
Described network pressure 0.9kgf/cm
2～3.0kgf/cm
2(former technology is generally 3.5～4.5kgf/cm
2); Network pressure suitably reduces makes processing back silk speed have suitable convergence, can not make fabric cause pit because of nexus again
The present invention has changed former technological process; make strand in a hot case by originally must via the outlet thread guide the Contact Heating mode change the noncontact mode of heating into; reduce the suffered friction of strand process and added temperature; avoided the generation lousiness; select cryogenic tensile distortion-high-temperature shaping (not using false twister) for use; use the suitable network nozzle, rationally control production technologies such as network air pressure cluster performance, can produce desirable similar flat traction machine product fullly drawn yarn (FDY) FDY product.
The present invention uses false twisting distortion elasticizer to produce the technology of another kind of polyester filament, on false twisting distortion elasticizer, carry out, it is characterized in that from the raw material strand of a roller through the inlet thread guide, directly undertaken after the noncontact heating to turning to thread guide by a hot case, cross twister, arrive the nozzle of interlace through two rollers again, advance two hot casees, the most laggard three rollers, oil tanker, coiling and molding get product; A described heater temperature is 80 ℃～120 ℃, and two heater temperatures are 120 ℃～200 ℃; Described network pressure 0.9kgf/cm
2～3.0kgf/cm
2The speed ratio of the described twister and the strand speed of service is 1.00～1.20.
Compare with last technology, increased false twister between thread guide and two rollers and carried out low false twist texturing turning to, can produce the strand cross section and have the good degree of hollowness and the demanding polyster fibre long filament of the fidelity performance stretch textured yarn such as degree of profile, degree of hollowness of special-shaped profile clearly, product strand cross section has good degree of hollowness and special-shaped clearly profile.
Because of the very low or not false twisting of last two series products false twists, the strand good operation stability, speed of production can improve relatively, and the speed of a motor vehicle of false twisting distortion elasticizer is that (the former speed of a motor vehicle is 500m/s～600m/s) to 600m/s～800m/s.
Aforementioned false twist texturing machine is all kinds false twist texturing machine.
The present invention need not change equipment, as long as technology is simply adjusted, promptly can produce draw textured yarn (DTY) such as terylene fullly drawn yarn (FDY) FDY and other polyester filament product and kind (as products such as thick dawn, thin dawn FDY), wide (the line density scope can reach 50D～350D) to the range of work than flat traction machine; Can also produce and have good degree of hollowness and the demanding polyster fibre long filament of fidelity performance stretch textured yarn such as special-shaped profile clearly, and the switching of two kinds of product technologies is flexible, effectively expand the scope of application of false twisting distortion elasticizer, had remarkable economic efficiency.
