Problems solved by technology

[0003] However, the polyester and viscose blended yarn spun by traditional ring spinning technology has the disadvantage of excessive hairiness, and the harm of yarn hairiness is directly manifested as: the adjacent warp yarns are entangled with each other during the weaving process, resulting in unclear openings, causing Difficulties in weft greatly increase the stoppage rate in the weft direction; new neps are formed on the yarn, which damages the appearance quality of the cloth; in the downstream processes, they fall off due to friction and form flying flowers, polluting the environment and endangering human health

Embodiment

[0029] Production of 32S65T / 35R polyester and viscose blended yarn for knitting.

[0030] (1) Opening and cleaning process

[0031] The technological process is FA002 automatic plucking machine → A034 mixed opener → FA106 porcupine opener → SFA161 vibrating cotton feeder → A076E(F) single hand lapping machine. The relative humidity of the workshop is 70-75%; the cotton rolls are covered with plastic film and left for 6 hours.

[0032] (2) Carding process

[0033] Use the FA212 carding machine to control the temperature and humidity in the workshop, and use a separate humidifier to locally humidify the relative humidity to 70-75% and the temperature to 21-24°C; the rotation speed of the cylinder is 330r / min, and the rotation speed of the licker-in roller is 810r / min, the speed of the doffer is 19r / min.

[0034] (3) Drawing process

[0035]Use FA317 type drawing frame, adopt three roads to mix, and wherein the draft multiple of mixing one operation is 1.73, and total draft m...

Abstract

The invention provides a spinning method of terylene-viscose blended yarn, which comprises the following steps: opening and cleaning cotton, combing the cotton, making ribbons, spinning coarse yarn and spinning fine yarn; while spinning the coarse yarn, feeding two pieces of coarse yarn in parallel into the same drawing mechanism of a spinning machine at 9-13 mm intervals so as to simultaneously draw the two pieces of coarse yarn in parallel. The method applies a Sirospun technology to the spinning of the terylene-viscose blended yarn. The two pieces of coarse yarn are simultaneously fed intothe spinning machine, the single yarn twist area is shorter, and the applied degree of twist is low, so that the included angle of the fiber spiral yarn and the yarn shaft in the single yarn is relatively small, and the single fiber in the single yarn can not transversely protrude out of the outer surface of the yarn due to the strong effect of the twisting force. Thus, the terylene-viscose blended yarn has the advantages of little filoplume, smooth surface, even yarn, high strength and few defects. The method enhances the quality grade of the terylene-viscose blended yarn.

Description

technical field [0001] The invention relates to the textile field, in particular to a method for spinning polyester and viscose blended yarn. Background technique [0002] Viscose fiber is moisture-absorbing and breathable. The fabric has the characteristics of soft hand feeling and good drapability. It is an excellent clothing material, but at the same time it has the disadvantages of large shrinkage, poor dimensional stability, easy to wrinkle, low strength, and dark color. Therefore, in order to overcome the disadvantages of viscose fiber, a certain proportion of polyester fiber is selected for blending. Through the advantages of polyester fiber, such as good luster, high strength, good elasticity, and anti-wrinkle, the advantages of the two are complementary, so that the final product has a soft and plump feel and comfort. taking performance. [0003] However, the polyester and viscose blended yarn spun by traditional ring spinning technology has the disadvantage of exc...
