Middle comb GB3 comb: 23.1～46.2tex spandex
Rear comb GB4 comb: the cotton bright and beautiful wrap yarn of 40～100S/2.2～4.4tex.
Raw material is transported to before use warping room constant temperature and is placed, and polyamide fibre first go up after yarn constant temperature 12 hours, and cotton yarn and spandex packing fill after constant temperature 48 hours or upper yarn constant temperature 12 hours.
The weight range of cotton yarn is 1.5～2.0kg/ cylinder.On creel, should reduce as far as possible bobbin draw distance during yarn and yarn degree of crook difference ，Sha road is short, thereby reduce the tension difference of each yarn, guarantee that whole yarn tension one highly causes.
Cotton yarn makes every effort to reduce the number of times through yarn sley when whole yarn, and dividing sinker number of times is more, and filoplume and flyings more easily generate, and is unfavorable for producing.Can adopt the method that reduces yarn arrays density at separating needle place, this is conducive to separate because of the yarn of filoplume adhesion, as two-layer in yarn one being divided into up and down every one with metal bar, can make yarn more be smoothly through separating needle.
The whole yarn static eraser of cotton yarn can save, the refueling device configuration that is absolutely necessary, and due to cotton yarn flyings, filoplume is many, and photoelectric detection system can optionally be selected.
On polyamide fibre and cotton yarn, on long filament warping machines, shake out creel during yarn, according to managing on unreeling direction, necessarily careful during pipe in attention, avoid artificial damage spool.Check whether the distance of shaking out on creel both sides equates, whether the direction yarn of brake puck is coated consistent, and the KFD of left and right creel adjusts scale value and whether equates.
The coated processing of cotton yarn: cotton yarn is coated to processing with chinlon filament, adopt with the sth. made by twisting of cotton yarn to contrary looping direction, so not only prevented the untwisting of cotton yarn, also increased the brute force of yarn, reduced the Yarn break under high-speed production, solved and in high plane No., weaved the young pilose antler that cotton yarn occurs and tangle broken yarn and weave the problems such as flyings.
After tension adjustment is good, again change coiled hair warping, step on slow train until new yarn around to the adjustment tension force of stepping on the gas after coiled hair.During start, every suit coiled hair carries out tension test one time, at least tests 4 one threads at every turn, and tension force is consistent with technological requirement.
Polyamide fibre, cotton yarn warping technology parameter:
Spandex thread warping: on spandex, yarn is wanted yarn in level, the spool of same case number (CN) should be distributed in the different lines of creel, during upper yarn, gets bobbin spring leaf, and upper complete clamping leaf spring again, then presses against spool on roller.Again yarn is put on, is divided to head expansion reed from creel, then check yarn radical, have or not reeled yarn, leak and to wear etc., if corrected.During start, every suit coiled hair carries out tension test one time, at least tests 4 one threads at every turn, and tension force is consistent with technological requirement.
Spandex warping technology parameter:
Through braiding, make the technological process of production
Board is adjusted (changing floral disc) → coiled hair quality examination → by axle in technological requirement → entry → adjust warp run-in → dossal → grey cloth density check → fabric quality inspection → start → cropping → weigh → pack → blank by technological requirement gear changing to put in storage.
