Integrated Spinning Technology

Fiber ends are easy to be extruded into yarns to form hairiness. The technology of collective spinning can effectively reduce hairiness.

< p > the so-called aggregate spinning technology is to use the collectors (bell trumpet) in the cluster area to cluster the finished yarn, which is to apply the D drafting principle of the roving frame to the spinning process, that is, before the main draft area of the traditional three roller double short apron drafting device, a pair of rollers is added to form a gathering area, and the collector in the assembly area is used to realize the cluster after the yarn drafting.

< p > remove the collectors in the original drafting area and optimize the distribution of frictional boundaries in the main drafting area to improve the yarn sliver quality.

The yarn twisting triangle area is reduced by the aggregation effect of the yarn, thereby reducing the hairiness of the yarn and reducing the loss of fiber. At the same time, the yarn in the yarn is more parallel and straightened so as to enhance yarn strength and so on. < a href= "//www.sjfzxm.com/news/index_c.asp" > /a >.

After assembling the assembly, the bar will get a certain convergence before entering the twisting triangle area. The width of the bar will be narrowed from width to width, and the twist triangle area will be smaller. The generation of hairiness will be controlled. Especially, the control effect is more significant for the 3 hairs.

< p > because the control of the yarn to the sliver is a rigid and inelastic control. Improper control will seriously affect the evenness of the yarn. Therefore, the outlet diameter of the collector can not be designed too small, so the effect of the cluster is limited. The control of Mao Yu 1~2 millimeter length will also have some influence.

< /p >

< p > although the gauze bar is subjected to certain aggregation before twisting, the yarn is still flat banded when twisting, and the generation of Mao Yu is inevitable.

< /p >

< p > but due to the decrease of twisting triangle area, the degree of internal and external metastasis of the fiber is controlled. The number of long hairs (mainly formed by the fibrous edges of the twisting triangle area) decreases accordingly.
