Equipment for producing direct melt filtration fused direct spun ultrafine denier polyurethane fibers

Abstract

The invention discloses equipment for producing direct melt filtration fused direct spun ultrafine denier polyurethane fibers. The equipment comprises a purification tank, a reaction tank, a metering delivery pump, a reactor heating mixer, a melt filter, a spinning box, a component filter screen spinning plate, an air channel cooling system, an oiling machine, a guide wire roller guide wire stretching device and a winder winding forming device. The invention has the advantages that: the ultrafine denier polyurethane fibers have small bending stiffness, soft handfeel and large surface area; the coverage, bulkiness and heat retention of a fabric are remarkably improved, and the fabric has strong cleaning function; the ultrafine fibers are prepared into an ultra-dense fabric, a gap among the fibers is between the diameter of a water drop and the diameter of a water vapor microdrop, and the ultra-dense fabric has a waterproof and ventilated effect; and the ultrafine fibers are processed into a towel fabric which can be wetted by water, and the towel fabric has high water absorption, and water of washed hair can be rapidly absorbed by using the towel, so that the hair is rapidly dried. The equipment can be applied to various fields.

Description

technical field [0001] The invention relates to a melting direct spinning superfine denier spandex fiber production equipment for direct melt filtration, which belongs to the technical field of spandex fiber production. Background technique [0002] Spandex scientific name <polyutethane>Fiber is a highly elastic synthetic fiber developed in recent years, also known as: Spenders <spandex>Fiber, PTMG accounts for 80% (mass molecule) of the final polymer, known as the "second skin" of people. It is highly elastic and can be stretched 6-7 times, but it can quickly return to its original state as the tension disappears. Its molecular structure is a chain-like, soft and extensible polyurethane. Hard segments link together to enhance its properties. At present, it is widely used at home and abroad: chemical spinning, wet spinning and dry spinning. The above three spinning methods will cause environmental pollution in production, complex process, large energy consumpt...

AI Technical Summary

Problems solved by technology

At present, the specifications of spandex fibers on the market include ultra-fine denier series (above 5D and below 20D) and conventional series (above 20D). There are only regular series of products, so the superfine denier series of melt direct spinning has always been a gap
