How to improve the quality of sliver and save cotton

Author:Xinjinlong Machinery-Fabric Recycling Machine Manufacturer

Improving sliver quality and saving cotton are two important tasks in the carding process. Special equipment for the textile industry on the winder. As the last process of spinning and the first process of weaving, winding is the link between the past and the next.“bridge”Therefore, it occupies an important position in the textile field.

Grinder A spinning machine that turns fiber strands into rovings. The main function is to draft and twist, and to wind the roving into a certain package to meet the processing requirements of the spinning frame. Carding machines are used to process cotton fibers and chemical fibers and belong to textile machinery.

According to the spinning process, carding is an important process. The front process of the carding machine is the opening and cleaning machine, and the latter process is the drawing frame (carding process) or the sliver coiler (combing process). Since the quality of the sliver is closely related to the drafting, yarn strength, and quality of the fabric in the rear design process, the control ability indicators for the quality of the sliver in the production environment include weight unevenness, sliver unevenness and sliver unevenness. The number of cotton trash particles per gram of sliver.

There is no unified national safety standard for the project management of these enterprises, which is researched and formulated by the students according to the conditions of raw cotton, the number of finished yarns and the development requirements of the quality of life. The raw sliver quantity is expressed in grams/5 meters (or Green/5 yards). Since the weight of the raw sliver fluctuates greatly and is not easy to control, the data we have obtained for different weights is only for reference. The weight unevenness of the sliver is controlled within 4%, and the sliver unevenness is controlled under 18%. And the clarity of cotton web can directly affect the quality of the company's products and services.

The so-called first-class cotton net in China refers to the uniform cotton net, no broken edges, holes, horizontal bars and two neps impurities. The poor definition and the loss of many holes in the cloud will seriously affect the information quality of my country's finished products, such as low spun yarn strength, uneven sliver, more self-points on the cloth surface and more slub yarns. Silver quality and quantity are closely related to the production of business cards. Generally speaking, the cotton of the Ministry of Industry and Information Technology has good sliver quality, but the amount of cotton used is increased.

or vice versa. Therefore, it must be manufactured according to the conditions and requirements of the material to establish a reasonable process condition to control the cotton, especially focusing on the control of the noil barb roller part, to make it within a reasonable range, both to ensure the yarn Sliver and mixed yarn knots ensure healthy cotton savings and improved economics.
