Abstract
The invention discloses a method for preparing a DTY (drawn textured yarn) polyester super-bright flat yarn by a POY (polyester pre-oriented yarn) polyester yarn, belonging to the field of knitting/spinning raw material processing technologies. According to the method, the POY yarn is rolled after passing through a first roller, an upper heating box, a cooling plate, a false twister, a second roller, a lower heating box and a third roller, and then the DTY polyester super-bright flat yarn is obtained, wherenin the linear velocity of the first roller is 410-450m/min; the linear velocity of the second roller is 690-720m/min; a temperature of the upper heating box is 193-196 DEG C; and a temperature of the lower heating box is 135-145 DEG C. The method has the advantages that the processing steps are simple and the industrial large-scale production can be satisfied; and as the linear velocities of the first and second rollers as well as the temperatures of the upper and lower heating boxes are selected reasonably, fleece-faced fabrics processed from the obtained DTY polyester super-bright flat yarn has smooth and soft handfeel as well as fluffy and vivid texture, which is markedly superior to that of the prior art.
Description
Technical field
The invention belongs to pin textile raw material processing technique field, be specifically related to a kind ofly prepare the method that the DTY terylene has much the light flat filament by the POY terylene thread
Background technology
in recent years, people require exquisite day by day to the style of terylene velour, be embodied in following two aspects: the one, sense of touch promptly requires feel smooth and soft; The 2nd, impression promptly requires matte plentiful and do not have and to subside, and hair root is life-like.Yet the fabric that adopts common DTY low elastic polyester filament to process in the prior art often is difficult to reach requirement.
have above-mentioned effect in order to make the velour that is processed by terylene thread as far as possible; Industry will be opened one's minds usually and concentrated in the finishing process; But facts have proved the effect that only can play a period of time, can't keep aforesaid sense of touch and impression effect enduringly.
Chinese invention patent application publication number CN101498058A discloses a kind of superfine flat terylene low-stretch yarn and production technology thereof; The specification of this silk is that 55-444dtex/144-576F, filament density≤0.58dtex and shape of cross section are the rectangle of length-width ratio>=2; The production technology of its recommendation is to adopt melt direct spinning mode, two steps of POY-DTY to produce route and produce, specifically can be referring to the 2nd page to the 3rd page of this patent application specification.But this patent application scheme processing step is loaded down with trivial details, is difficult to adapt to the industrial amplification production requirement, therefore is necessary to improve.Especially; In disclosed patent and non-patent literature, all be not seen in the POY terylene thread is processed into the teachings that the DTY terylene has much the light flat filament; For this reason, the applicant has done useful exploration, and the technical scheme that will introduce below produces under this background
Summary of the invention
task of the present invention is to provide a kind of and prepares the method that the DTY terylene has much the light flat filament by the POY terylene thread; This method processing step is terse and can satisfy the industrial amplification production requirement; And the velour lining that is processed by the DTY polyester fibre flat silk that this method obtains not only has desirable smooth and soft effect, and has excellent fluffy plentiful effect.
task of the present invention is accomplished like this; A kind ofly prepare the method that the DTY terylene has much the light flat filament by the POY terylene thread; It is that the POY silk is reeled behind first roller, last heating cabinet, coldplate, false twister, second roller, following heating cabinet and the 3rd roller successively; Obtain the TDY terylene and have much the light flat filament, the linear velocity of described first roller is 410-450m/min, and the linear velocity of described second roller is 690-720m/min; The described temperature that goes up heating cabinet is 193-196 ℃; Described heating cabinet temperature down is 135-145 ℃.
Drafting multiple between
first, second roller of the present invention is 1.533～1.743 times.
technical scheme processing step provided by the invention is simple, can satisfy the industrial amplification production requirement; Because the linear velocity of first, second roller is selected rationally and the temperature of upper and lower heating cabinet is selected rationally, after being processed into velour, has smooth, soft hand feeling and the fluffy texture true to nature that significantly is superior in the prior art thereby can make the DTY terylene that obtains have much the light flat filament.
The specific embodiment
Embodiment 1:
will be that the POY terylene thread (preorientation terylene thread) of 277D/288F is drawn by bobbin cradle by commercially available specification; Reel by way of first roller (also can claim feeding roller), last heating cabinet, coldplate, false twister, second roller (also can claim drawing rollers), following heating cabinet and the 3rd roller (also can claim delivery roller) back successively; The DTY terylene that obtains 150D/288F has much the light flat filament; Wherein: the linear velocity of first roller is 450m/min; And the linear velocity of second roller is 690m/min, and drafting multiple (DR) is 1.697 times; The temperature of last heating cabinet is 196 ℃, and the temperature of heating cabinet is 142 ℃ down.
Embodiment 2:
only the linear velocity with first roller change 410m/min into, change the linear velocity of second roller into 720m/min, and drafting multiple (DR) is 1.533 times; Change the temperature of last heating cabinet into 193 ℃, change the temperature of playing heating cabinet into 145 ℃.All the other are all with the description to embodiment 1.
Embodiment 3:
only the linear velocity with first roller change 430m/min into, change the linear velocity of second roller into 710m/min, and drafting multiple (DR) is 1.743 times; Change the temperature of last heating cabinet into 194.5 ℃, change the temperature of playing heating cabinet into 135 ℃.All the other are all with the description to embodiment 1
Claims (2)
1.
are a kind of prepares the method that the DTY terylene has much the light flat filament by the POY terylene thread; It is characterized in that it is that the POY silk is reeled successively behind first roller, last heating cabinet, coldplate, false twister, second roller, following heating cabinet and the 3rd roller; Obtain the TDY terylene and have much the light flat filament; The linear velocity of described first roller is 410-450m/min, and the linear velocity of described second roller is 690-720m/min; The described temperature that goes up heating cabinet is 193-196 ℃; Described heating cabinet temperature down is 135-145 ℃.
