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 i

Example Embodiment

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

[0036] The following examples do not limit the bicomponent spinning machine, because although the manufacturers and models of the bicomponent spinning machine are different, they do not affect the preparation of the ultrafine fibers.

Example Embodiment

[0037] Example 1

[0038]As shown in the accompanying drawings, the present invention is based on ordinary bicomponent fiber production equipment for the production of recycled polyester superfine fiber POY, which consists of recycled polyester beverage bottles that are cut, dried, and then melted for pelletization. Ester chip A and water-soluble polyester chip B are used as 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). Recycled polyester chip A and water-soluble polyester chip B The two raw materials are respectively dried by the crystallization dryer 1 and extruded and melted by the extruder 2 and then sent to the composite spinning box 3. The insulated spinning metering pump is accurately metered and extruded, and is distributed to each composite spinning assembly. The island component is evenly distributed in the sea component and is extruded together to the composite compo...

[0042] Example 2

[0043] As shown in the accompanying drawings, the present invention is based on ordinary bicomponent fiber production equipment for the production of recycled polyester superfine fiber POY, which consists of recycled polyester beverage bottles that are cleaned, sorted and shredded by recycled polyester chips. And water-soluble polyester chips B as raw materials (the intrinsic viscosity of recycled polyester chips C is 0.736, and the intrinsic viscosity of water-soluble polyester chips B is 0.643). The two raw materials are crystallized, dried, extruded and melted, and then sent to the composite Spinning box 3 is accurately metered and extruded by a thermally insulated spinning metering pump, and is distributed to each composite spinning component. The island component is evenly distributed in the sea component to the composite component, and then extruded through the side It is formed by cutting wind and cooling, the oil nozzle 4 is oiled, and guided by the firs...

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...
