Abstract

The invention relates to a filament splitting constant-tension double-side limiting composite spinning device, method and application. The device is composed of a yarn guide hook, a flattening roller group, a splitting rod, an interval rod, a guide roller and the like. The spinning method comprises the steps of: flattening and outputting a beam of no-twisting filaments through the flattening roller group; symmetrically splitting the filaments along a central line when meeting with the tip end of the splitting rod; determining a separating interval of the two beams of the filaments by the interval rod; then using the double filaments to wrap a short fiber whisker strip in a twisting triangular zone after the double filaments are fed into a jaw of the front roller via a way of adjoining two sides of the short fiber whisker strip via constant tension through the guide roller so as to form the smooth composite yarn without self-twisting filament wrapping the short fiber strip. The device and the process are simple and practical, can efficiently improve spinning efficiency of fibers and reduce flying, scraps and fluffs in the spinning process, and are suitable for composite spinning of high-count smooth yarns and superfine yarns of shorter, weaker and ultra-short fibers.

Description

technical field [0001] The invention relates to a filament unfolding and protection type composite spinning device, a spinning method using the device and an application of the device. Background technique [0002] On the one hand, there is a shortage of fiber resources, and on the other hand, a large amount of processed and used fibers are discarded. The reason is not that people do not want to use them, but that these fibers are short or ultra-short, weak or fragile, and traditional spinning technology is difficult Spinning or not being able to spin at all. Modern composite spinning technology, especially continuous and reinforced composite spinning with filaments, provides the possibility for the recycling of such fibers. Unfortunately, the existing composite spinning technologies are all used for high-quality fibers. [0003] For example, Wang Qiang et al. have a patent on filament and short fiber composite yarn (patent publication number: CN101775679A), in which three...
