Spinning Of Compact Spun Yarn With Non Treated Cots

Because compact yarn With special yarn forming mechanism and yarn structure, the quality of spinning equipment such as cots is raised. There are two kinds of cots in compact spinning, one is the drafting cots, the other is the gathering cots.

The former is composed of a powerful forceps made of roller friction drive and rollers, which can effectively grip the whiskers and fibers, form an appropriate and stable grip force, and ensure normal draft operation; the latter is the key part of the output mechanism and the output roller or the special shaped tube is the output jaw, which has the function of discharging compact fibers, controlling the fiber bar in the gathering area, and preventing the twisting area from uploading.

In order to meet the demand of intensive spinning of fine count yarn, especially for the demand of super fine yarn, our company has developed and developed CF2.9tex long staple cotton super fine count cotton compact spinning. CF2.9tex yarn is super fine yarn. Its yarn diameter is small, the number of fiber roots is very small (about 20). The cohesion and cohesion of the fibers are low, the yarn strength is low, the yarn breakage is more, and the spinning process is more difficult.

Especially Spun yarn Due to the small number of fiber roots in the cross-sectional area of the unit, the process results in yarn Its strength can not bear external resistance and cause a sharp increase in broken ends, which can not produce normally.

In order to reduce the broken ends, we have taken some measures: we should use the WRC-963, WRC-365 and WRC-965 type non treatment cots to excavate the potential of spinning before ensuring the normal production and good quality of the semi-finished products.

The WRC-365 type cots are better than the WRC-965 type cots in stability, consistency and long-term adaptability. The WRC-365 type surface non treatment cots have the characteristics of strong spinnability, good moisture absorption and moisture release, good surface cleanness and good resistance to winding. It is closer to the overall performance of the imported cots J-463 in the production of super fine yarn, and can meet the requirements of the production of CF2.9tex super fine yarn.
