Problems solved by technology

[0006] In recent years, with the emphasis on the recycling of resources, the production of recycled polyester products has been widely valued. However, due to the relatively poor performance of recycled polyester products, when spinning fine denier fibers due to the high content of impurities, spinning During the process, the phenomenon of floating and broken ends is serious, and the strength of the obtained fine denier fibers is poor, so it is difficult to obtain applications in fine denier and ultrafine denier fibers. Therefore, currently recycled polyester is mainly used in hollow fibers, short fibers and some In the production of conventional filament products, it cannot be applied to the direct spinning of superfine fibers

[0035] In the preparation process of the product of the present invention, the raw materials and methods in the fiber material obtained by the two-component spinning machine and the alkali hydrolysis method in the peeling process all belong to the technical content known to those skilled in the art and production personnel, so in the specific examples This part is omitted.

[0036] The two-component spinning machine is not limited in the following examples because although the manufacturers and models of the two-component spinning machines are different, they do not affect the preparation of the ultrafine fibers.

Embodiment 1

[0038]Referring to the accompanying drawings, the present invention is based on ordinary bicomponent fiber production equipment for the production of recycled polyester superfine fiber POY, which is respectively made of recycled polyester beverage bottles that are shredded, dried, and then granulated for granulation. Ester chip A and water-soluble polyester chip B are raw materials (the intrinsic viscosity of recycled polyester chip A is 0.695, and the intrinsic viscosity of water-soluble polyester chip B is 0.643), and the recycled polyester chip A and water-soluble polyester chip B are The two raw materials are respectively dried by the crystallization dryer 1, extruded and melted by the extruder 2, and then sent to the composite spinning box 3, accurately metered and extruded by the heat-preserved spinning metering pump, and distributed to each composite spinning assembly. The island component is evenly distributed in the sea component and extruded together to the composite ...

Abstract

The invention discloses a method for producing regenerated polyester ultrafine fiber based on bicomponent fiber production equipment. The method comprises the following steps: a regenerated polyester slice and a water soluble polyester slice are used as raw materials; after the two raw materials are subjected to crystallizing and drying, extruding and fusing respectively, the two raw materials are fed to a composite spinning manifold, are extruded through an insulated spinning metering pump with accurate measurement, and are distributed to each composite spinning component; the two components are compounded to be shaped according to shapes set by a spinneret component, are extruded to be shaped through side ram cooling and oiled by a nozzle tip, and are wound by a winding head to form a regenerated polyester ultrafine POY spinning cake; and then the spinning cake is processed to obtain an applicable ultrafine fiber through subsequent texturing. After the method is adopted, through adjusting the processing technology, the regenerated polyester raw material can be applied to high grade fiber so as to improve effective application of resource, and save cost. The method has double significances of economy and environmental protection.

Description

technical field [0001] The invention relates to a superfine fiber material and a production method, in particular to producing the superfine fiber material by using a regenerated polyester raw material through a melting composite spinning method. Background technique [0002] Microfiber refers to special fibers with a monofilament fineness below 0.44dex. Because the fibers are very thin, the fabric feels soft, the surface is fluffy, the appearance is plump, and it has the functions of waterproof, breathable and moisture permeable. Once the microfiber appeared, it had a great impact on the clothing market, changed people's traditional views on chemical fibers, and provided a new way for the production of new fabrics that combine comfort, functionality, and softness. [0003] There are many kinds of production technologies for ultrafine fibers. In addition to the commonly used direct spinning and composite spinning methods, there are also methods such as super-drawing, instant...
