Embodiment Construction

[0014] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in combination with the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0015] The draft-cut strip-making method utilizing the strip-making machine of the present embodiment comprises:

[0016] Step S1, increase the nip pressure of the front roller of the strip making machine to 1280-1360 Newtons, and adjust the number of needle plates of the strip making machine to 17-20, and the needle plates are evenly distributed, that is, the needle plates are evenly distributed in the original space range Inside, the needle density on the needle board is 10-1...

Abstract

The invention relates to the textile technology field, and discloses a stretch-breaking slivering method using a slivering machine; the method comprises the following steps: S1, increasing the front roller jaw pressure of the slivering machine up to 1280-1360 Newton, adjusting the slivering machine needle plate quantity as 17-20 pieces, and evenly spreading the needle plates, wherein the needle plate needle density is 10-12needle / inch; S2, continuously feeding raw material fiber bars into the slivering machine, stretch-breaking the materials, and slivering same. The method can increase the slivering machine front roller jaw pressure, thus increasing fiber handling force, breaking the fiber, reducing the needle plate number and density, and smoothing the stretch-breaking process after reduction.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a stretch-cut strip-making method using a strip-making machine. Background technique [0002] The sliver making machine is a common machine in the textile field. It mainly includes a drafting device composed of front and rear rollers and needle plates between them. It drafts and combs the raw fiber bundles entering it to make the fibers straight and parallel. into continuous fibers. in the existing process. When the sliver machine produces hemp slivers, when the hemp flakes enter the process before the sliver machine, the fibers of the hemp are very long, with a length of about 0.4 to 1.2 meters. Since the sliver machine has no pulling and cutting function, it must be cut in the previous process. The hemp fiber is cut into a length of about 100 mm, and then fed into the sliver making machine to produce slivers normally. [0003] For example: the acrylic sliver is produced by ...
