Problems solved by technology

The sea-island ultrafine composite fiber is made of polyester polyester chip (PET) as the island component and low-melting point polyester (COPET) as the sea component. It is extruded by a screw extruder, melted and fed into the spinning box, and passed through a metering pump. Precisely metered, distributed to each spinning component, evenly distribute the island component in the sea component, carry out conjugate spinning to form sea-island composite fibers, and then use the alkali-soluble characteristics of low-melting point polyester to remove the sea component , you can get very fine island component monofilament, the monofilament fineness is only 0.05 denier, which is 1 / 40 of conventional fiber (conventional fiber fineness 2-4 denier), this kind of extremely fine silk, spinning with conventional chemical fiber Silk craft is unable to spin

Abstract

A technology for spinning superfine islands-in-sea bicomponent fibre from polyester chips, and low-smelting-print polyester chips includes respectively heating, extruding, smelting and metering, mixing in spinning assembly, jetting two from spinneret plate, cooling by lateral wind coating oil, spinning and winding. Its advantages are continuous production and high automatization level.

Description

(1) Technical field [0001] The invention belongs to a chemical fiber production process, in particular to a sea-island superfine composite fiber spinning production process. (2) Background technology [0002] Sea-island superfine composite fiber is the thinnest fiber in the world today, and it is an ideal raw material for producing high-grade clothing fabrics. The sea-island superfine composite fiber used in my country's clothing fabric processing industry is all dependent on imports, spending a lot of foreign exchange. The sea-island ultrafine composite fiber is made of polyester polyester chip (PET) as the island component and low-melting point polyester (COPET) as the sea component. It is extruded by a screw extruder, melted and fed into the spinning box, and passed through a metering pump. Precisely metered, distributed to each spinning component, evenly distribute the island component in the sea component, carry out conjugate spinning to form sea-island composite fibers...
