Fused direct spinning hyperfine denier polyurethane fibre device in single static agitated reactor

Abstract

The invention relates to a fused direct spinning hyperfine denier polyurethane fibre device in a single static agitated reactor, which is characterized by comprising a purification tank, a reaction tank, a metering delivery pump, an agitated reactor heating mixer, a static agitated reactor, a two-screw extruder, a flux filterer, a spinning box, an assembly filter screen spinneret plate, an air duct cooling system, an oiling device, a silk guide roller conducting wire stretch device and a coiler winding and molding device. The device has the advantages that the bending stiffness of the produced hyperfine denier polyurethane fibre is extremely small, and the hand feel of fibre is especially soft; the superficial area of the fibre is large, the coverage, bulkiness and heat retention of fabric are obviously improved, and the cleaning function is extremely strong; hyperfine fibres are manufactured into super-high density fabrics, a gap between the hyperfine fibres is between the diameter of water drop and the diameter of water vapor micro-drop, and have waterproof and ventilation effects; and the fibre can be processed into towel fabric which has the characteristic of high water absorbability, and if the towel is used, the water on washed hair is absorbed rapidly so as to fast dry the hair. The device can be applied to various fields.

Description

technical field [0001] The invention relates to a melting and direct-spinning superfine-denier spandex fiber equipment capable of reacting in a single static reactor, and 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 ener...

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
