Problems solved by technology

However, in this patent, the speed of the three pairs of hot rollers is constant. Although the fineness is guaranteed to be uniform, the tension of the yarn cannot be adjusted, and the positions of the three pairs of hot rollers are fixed, which brings inconvenience to the adjustment of the fineness and tension.

Embodiment 1

[0029] 1. Prepare 200D jelly silk, put it into the silk barrel 2 and let it stand for several days, waiting for the phase separation to end.

[0030] 2. Bundling: After the phase separation, the jelly filaments 6 are neatly discharged to the cluster frame 1, and divided into three rows, with three barrels in each row. The jelly filaments in the barrels are evenly spread out, and the filaments are actively and orderly discharged, and they are reciprocated in turn. After the rod 3, the circular ring buckle below the godet 5, and the three rolls a, b, and c in the active bundle traction roll group 4, it is drawn to the pre-drawing place. Wherein, the reciprocating rod 3 reciprocates at a uniform speed with a stroke of 10 cm to prevent the filaments from sticking. The diameters of the three rollers in the active cluster traction roller group 4 are 15cm, the distance between roller a and roller c is 30cm, and the roller b moves down 25cm from the same plane of roller a and roller c...

Abstract

The invention provides a fiber drawing method. The fiber drawing method comprises the steps of preparing gel-spun fibers, bundling and pre-drawing, extracting, drying and hotly drawing, and is characterized in that an initiative fiber feeding procedure is increased before the step of bundling and pre-drawing. With the adoption of the fiber drawing method, the fineness deviation of the fibers can be reduced and the dispersion degree of the fineness of the finished-product fibers is also reduced; meanwhile, waste fibers generated in a drawing procedure are reduced and the cost is saved; the tension of the gel-spun fibers can be conveniently adjusted and keeps constant in a drawing process; meanwhile, the manpower is saved and the labor production efficiency is improved.

Description

technical field [0001] The invention relates to an improved drafting process in the fiber production process, in particular to a drafting method in the production process of ultra-high molecular weight polyethylene fibers, and the drafting method can reduce the fiber fineness deviation. Background technique [0002] In the production process of ultra-high molecular weight polyethylene fibers, gel spinning method is generally used. When the jelly yarn is drawn, it is generally put on the cluster frame first, then pre-drawn, extracted, dried, and finally hot-drawn to obtain fiber strength. In order to improve production efficiency, there are as many as three or four rows of fibers bundled in each batch. It is necessary to control the opening angle and keep the tension constant, which makes it more difficult to ensure the uniformity of the jelly yarn. [0003] In the existing production drafting process, the bunching rollers are all passive rollers, and the jelly yarn is more ...
