专利说明:

This invention relates to the manufacture of a base or sectional base from chemical threads.
The purpose of the invention is cost reduction.
To achieve this goal, use the strand of the spinning machine on not less than 24 coils, which is not completely stretched. The strand is crushed from these cobs under constant tension while maintaining the parallelism of the threads to each other by means of a comb thread guide. The warp threads pass through a system of feed and support rollers operating at a constant peripheral speed. The yarns are then passed along to a bark of thermostatic liquid, which is maintained at a certain temperature so that the yarn filaments are drawn. After exiting the barge, the yarn passes through a system of tension rollers operating at a constant peripheral speed, exceeding the peripheral speed of the feed rollers. These rollers also remove excess water from the yarn. The required stretching and molecular orientation of the individual elemental fibers are achieved between the feed and the tension rollers due to their circumferential speeds, which create tension, and the plasticization of the polymer is provided by the heat of the bath. Then the yarns are passed through the entangling devices, which interlace the filaments with the effect on the last high-speed liquid jets. These devices are arranged in sets, respectively, separately for each thread. The method involves pre-transfer processing prior to the stretching stage. In this case, the pneumatic devices are mounted on the reel-holder of the feed unit. Next, the yarns are dried, which can be performed after the exhaust bath or before or after the entanglement. Drying is carried out by passing the filaments through the furnaces or the heated cylinders and T.D. The yarn is then wound around the warp rolls.
The proposed method makes it possible to eliminate the pre-stretching of the threads, as well as to carry out the process without the need to use a sizing agent. Meshing is achieved on texturing devices.
For the implementation of the method using polyester. Polyamide, polyethylene, polypropylene yarns and their modification.
Example. 1000 ears of partially oriented mosid polyether-. pry yarn with the following characteristics: N yarn 127 decitex, the number of filaments with a round
a cross section of 24, a breaking load of 330 g, an elongation at break of 156%, a theoretical residual stretch of 1.628 / 127/78, placed on the bobbin holder of the thread, woven into the bobbin holders of the feed, and then distorted under tension of 10 g, passing through tooth comb
The yarns are fixed and tensioned at a tension of 10 g by means of a three-roll system, the rollers of which rotate with a constant speed of 130 m / min. They are then immersed in a barque of demineralized water with
.
The system of three exhaust and squeezing cylinders, rotating together with a constant speed of 220 m / min, acts on all the filaments, communicating to them a stretch of about 1.692. Then the threads pass through jets of air-bypass devices supplied at a pressure of 3 atm. They are further dried and fixed, passing through the system into seven rotating-heated cylinders, of which the first is heated to ISO C and the last to 90 ° C. The speed of the cylinders is slightly below 220 m / min. Thereafter, the threads are wound on warp rollers, having a size of 1,800 mm at a height of six sections of 16000 meters in length.
Characteristics of the resulting base: N yarn, decitex 82 Tensile strength321
Elongation at
break,% 34
Shrinkage in boiling water,% L 2
During the next stage, these six sections are wound onto weavers with a height of 1,550 mm, while doing a total of 6,000 strands of yarn. The substrate is then subjected to further processing. The fabric from the resulting base has a high degree of od
the uniformity and compaction of interwoven threads.
