Purpose of the present invention is to provide one to utilize the direct fabrics extension device to produce filament-blended profiled-section combined filament yarn to simplify manufacturing step and to avoid the resting period to influence the manufacturing processing procedure of combined yarn quality.
The inventor develops the procedure for producing that direct fabrics extend filament-blended profiled-section combined filament yarn, and the result through the test of concentrating on studies is produced works out finally with higher spinning temperature (being higher than 290 ℃), long extension heated time 1.0 * 10
-3-2.0 * 10
-3Divide and coiling tension less than (0.25*Den) gram, the finish of the coefficient of kinetic friction (F/M μ d) 〉=more than 0.330.Can obtain between good metachromia and monfil maximum degree of stretching poor 〉=40% former spinning cake.Describe technology contents of the present invention in detail in following:
Filament-blended profiled-section combined filament yarn of the present invention, its spinnerets is combined by three kinds of above spinning nozzles of section, the section configuration of the spinning nozzle of spinnerets that the present invention adopts as shown in Figure 1, as Fig. 2, direct bearing of the present invention uses the spinnerets (2) with different section spinning nozzle more than three kinds, melt and dissolved condensate heats after spinnerets (2) ejection is cooled off through the cooling air of cooling air device (4) for tow (3) again in the spinneret (1) of 290-310 ℃ of temperature, boundling is gone into after oil nozzle (5) oils greater than the finish more than 0.330 with the coefficient of kinetic friction (F/M μ d), tow draws into heated wheel (6) with the heating of 70-120 ℃ temperature, heat time heating time 1.0-2.0 * 10
-3Divide, again after extension HEAT SETTING wheel (7) is with 1.30-1.70 times extension ratio extension, tow draws behind contact wheel (8) again, to feed rate greater than 1.0%, coiling tension is less than the tension force of (0.25*Den) gram, batch with the coiling speed that is higher than 3000 meters/minute and to be former spinning cake (9), extend processing procedure through above direct fabrics and can obtain to supply the filament-blended profiled-section combined filament yarn that fine thing uses, must not process and avoid not extending silk through above-mentioned transfer extension of stretching the sth. made by twisting process again and deposit the influence of factor, more can improve output because of the raising of rolling up speed to quality.
The main composition key element of the combination of monofilaments of combined yarn of the present invention, for the monofilament above macrofibril of 3 red Buddhist nuns and thin fibril below the 1.5 red Buddhist nuns are lumped together and section configuration tool projecting point, thick fibre and thin fine spinning nozzle section can have 6 kinds, so silk can get the fine thing of the fluffy sense of dry refreshing soft tool after fibre is made, so its monofilament that can obtain different fiber numbers and degree of stretching, tie up in six kinds of spinning nozzle basal areas and vary in size, in the same spinnerets, the sectional area of single hole more then discharge-amount is bigger, bigger in the spinning nozzle initial velocity, under certain coiling speed, (Draft Ratio) is less for the spinning draw ratio, and filament number is bigger, and degree of stretching is higher, otherwise then the fiber number of monofilament is less, and degree of stretching is lower; For improveing above-mentioned shortcoming, finish the present invention through studying intensively.
Monofilament degree of the stretching maximum difference of the combined yarn of applicant's invention is more than 40%, and the degree of stretching of adjacent monofilament difference is below 10%, usually then below 5%.Owing to like this monofilament degree of stretching difference makes that after the fine cloth dyeing and finishing, cloth cover has bulkiness, if the too small then fluffy poor effect of degree of stretching maximum difference between monofilament; It is unfavorable that adjacent monofilament degree of stretching difference is too greatly then produced, easily fracture of wire.
The present invention has multiple different section spinning nozzle on a spinnerets for utilizing, if spinning temperature is crossed and is lower than 290 ℃ and will causes and polymericly flow not goodly, distributes uneven and causes to spue and have some setbacks, and easily fracture of wire can't be produced.
The too low frictional force deficiency that then causes between tow and heated wheel of the coefficient of kinetic friction of finish, and then make the tow slip swing, cause the disrumpent feelings silk that twines of bundle, the dyeability inequality of silk.
The heated wheel heating-up temperature is too high, heat time heating time is oversize, can cause tow too soft and on heated wheel, swing, and cause the phenomenon that tow is disrumpent feelings and metachromia is uneven, and the heated wheel temperature is too low, and heat time heating time is too short, then causes the molecule in prepattern district fully not loose, when extending, will have and extend bottle head (NECK) generation and cause fracture of wire, if use lower extension ratio then to cause the phenomenon of extending the not enough dyeability inequality of orientation.
The Tension Control that over feed rate(OFR) after extending batches causes greater than (0.25*DEN) Ke Shiyi for the very big coiling tension of influence of spinning cake moulding and throws silk and moulding and lift up the angle and alleviate difficult.
For solving the above problems, wait and tax one's ingenuity through the applicant, study intensively, according to aforementioned of the present invention create conditions to produce can obtain productivity, the filament-blended profiled-section combined filament yarn that easy zbility is good.
