High Efficiency Production By Light Pressure Technology

< p > high efficiency technology has been favored by many spinning mills due to its advantages of saving electricity, saving labour and saving costs.

Although many enterprises adopt the technology of "heavy pressurization and strong control" at present, however, after long-term exploration, we find that the pressurization of 100N/ double ingots (hereinafter referred to as "light pressure") can also be used in high efficiency process. For this reason, we preliminarily studied the spinning equipment of light pressure technology.

< p > > a href= "http:// www.sjfzxm.com/news/index_c.asp" > light pressure < /a > means that the front frame pressure of cradle is small (relative to 180N/ double ingots), which can be spun under the pressure of not more than 100N/ double ingot, which can save energy and reduce consumption, reduce the load of drafting system, reduce the abrasion of rollers' bending and pmission parts, prolong the service life of cradles, and roll back cycle of rubber cots.

< p > in order to study the application of 100N/ double ingot high efficiency technology, we try to spin siro spinning with R19.4tex variety.

The experiment shows that the yarn quality when the pressure is 100N/ double spindle is higher than that of 180N/ double ingot.

At the same time, in this process, we have adopted a large diameter, low hardness and high elastic cots.

< p > because of the large deformation of the diameter, it not only reduces the difference between the peak and trough of the grip force, makes the dynamic holding force relatively stable, but also increases the contact coverage of the cots and the lower grooves, thereby improving the yarn quality.

< p > because compact spinning has 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 as the key part of the output mechanism and the output roller or special-shaped tube constitute the output jaw, which has the output of compact fiber whiskers, which controls the fiber bar in the gathering area, and prevents the twisting area from twisting and uploading.

< p > in order to meet the demand of intensive spinning of fine count yarn, especially for the demand of super fine yarn, we have organized 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.

< /p >

< p > especially in the spinning process, because the number of fiber roots in the unit area is very small, the yarn itself can not be loaded with external resistance and 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.
