Multi-head chemical fiber monofilament spinning assembly

Abstract

The invention belongs to the technical field of a textile, and relates to a spinning assembly, particularly to a multi-head chemical fiber monofilament spinning assembly, which solves the technical problem of the unreasonable design in the prior art. The multi-head chemical fiber monofilament spinning assembly comprises a feeding plate, a distribution unit and a spinneret plate arranged in sequence; the spinneret plate is provided with at least two spinneret orifices; the feeding plate is provided with polymer inlets having the same number as the spinneret orifices; the polymer inlets and the spinneret orifices are arranged in a one-to-one correspondence way; and each polymer inlet is connected with the outlet of a metering pump with independent metering function. Compared with the prior art, the multi-head chemical fiber monofilament spinning assembly has the advantages that: the multi-head chemical fiber monofilament spinning assembly is reasonable in design and simple in structure; and more than two spinneret orifices are arranged on the spinneret plate, and the spinneret orifices on the spinneret plate are correspondingly provided with the polymer inlets capable of independently controlling flow quantity, so that the monofilaments spun by the spinneret plate can be effectively ensured to be uniform in thickness and equal in fineness.

Description

technical field [0001] The invention belongs to the technical field of textiles, and relates to a spinning assembly, in particular to a multi-head chemical fiber monofilament spinning assembly. Background technique [0002] In the production process of chemical fibers, most of them adopt the production process of melt spinning. The function of the spinning assembly is to fully mix and filter the spinning melt, so that the melt is extruded through the spinneret holes on the spinneret to form filaments at high pressure. Each part of the spinning assembly is responsible for distributing the melt, mixing And the function of filtering the spinning melt. Spinning components are widely used in the field of textile technology for the production of chemical fiber materials such as polyester, nylon, polypropylene, spandex, melt-spun filaments and short fibers. Most of the known spinning components are self-sealing, including a component shell, a spinneret is arranged inside the comp...

Problems solved by technology

However, this scheme still only has one polymer inlet, and the distribution of the polymer is realized through the internal structure design. The distribution plate and the sand cavity inside the spinning pack distribute the melt to the spinneret holes on the spinneret. When there are multiple monofilaments arranged on the spinneret, it often leads to defects such as different fineness and uneven thickness between the monofilaments.
