Pindarl fiber yarn manufacturing process

Abstract

The invention discloses a pindarl fiber yarn manufacturing process and belongs to the yarn manufacturing technology. A conventional ring spinning technology for spinning Pindarl fiber yarn is difficult in spinning and poor in yarn forming quality. The pindarl fiber yarn manufacturing process includes: binding in strips via a cotton carding machine, and manufacturing fiber rods which are 330-350grams / hectometer by means of performing carding, impurity removing and uniform mixing under the conditions that a licker-in speed ranges from 800 revolutions / minute to 1000 revolutions / minute, a cylinder speed ranges from 300 revolutions / minute to 350 revolutions / minute and a doffer speed ranges from 21 revolutions / minute to 24 revolutions / minute; spinning via an air-jet spinning machine, feeding the fiber rods manufactured in the step 1 into the air-jet spinning machine, and entering nozzles after four-roller drafting, wherein air pressure of the first nozzle ranges from 0.30Mpa to 0.40Mpa, air pressure of the second nozzle ranges from 0.45Mpa to 0.55Mpa, upper roller center distances are 48mm / 41mm / 42mm, lower roller center distances are 44mm / 41mm / 42mm, a total drafting multiple is 170.65, a main drafting multiple is 33.11, an intermediate drafting multiple is 2.58, a rear drafting multiple is 2, the distance between a front jaw and the first nozzle is 15mm, an output speed is 200m / min, an opening of a cotton collector is 2mm, an overfeeding ratio is 0.96, and an output ratio is 0.98. A yarn twist multiplier ranges from 300 to 350, and the manufactured Pindarl fiber yarn is 15-28 (tex).

Description

technical field [0001] The invention belongs to the technical field of yarn manufacture, and in particular relates to a manufacturing process of Pindarl fiber yarn. Background technique [0002] With the continuous development of nanotechnology research at home and abroad, the development and application of new textile materials will play a very active role in promoting the technological progress of the textile industry. Pindarl fiber is a kind of textile raw material obtained by modifying the surface of cellulose fiber with nano-crystallization layer treatment technology in my country. Compared with ordinary cellulose fiber, it has better quality, smoother, softer hand feeling, and better wet strength. There is a significant improvement. Pindarl fiber can be used to make underwear, pajamas, T-shirts, shirts, bedding, etc.; the fabric is breathable and smooth, making it more comfortable to wear; it can be blended with cashmere and other fibers to increase the smoothness and ...
