Problems solved by technology

[0003] The existing 1.2-denier polyester staple fiber is all made of virgin polyester chips and melt direct spinning, and its products are commonly referred to as "big chemical fibers". Because both virgin polyester chips and melt direct spinning require a large amount of Oil refining, high cost, limited resources
At present, the high-strength 1.2-denier polyester staple fiber made of waste polyester materials has not been reported in the literature.

Embodiment Construction

[0013] refer to figure 1 , the existing spinning assembly is composed of an assembly headgear 3, a pressure plate 5, a distribution plate 6 and a spinneret 7, and the pressure plate 5, the distribution plate 6 and the spinneret 7 are fixedly connected to the assembly headgear 3 through a pressure ring 8 Below, the melt inlet 2 is arranged on the side of the assembly headgear 3, and the upper part of the assembly headgear 3 is provided with a lifting ring 1.

[0014] refer to figure 2 The difference between the spinning pack described in this embodiment and the spinning pack of the prior art is:

[0015] a) Add a sea sand filter 4 in the spinning assembly, the sea sand filter 4 consists of a positioning ring 41, a 250-mesh metal filter 42 arranged above the positioning ring, a 250-mesh metal filter 43 arranged below the positioning ring and Sea sand 44 is filled between the two layers of metal filter screens. The design value of the thickness of the sea sand filter layer is ...

Abstract

The invention relates to a spinning device of regenerated polyester fibers, which comprises a component cap, a pressing plate, a distribution plate and a spinneret plate. A sea sand filter is arranged on the pressing plate, and the sea sand filter, the pressing plate, the distribution plate and the spinneret plate are fixedly connected under the component cap through a pressure ring. Because the sea sand filter is added to a high-pressure jet spinning device, and a fused melt is extruded to enter a spinning box via the filter and then enters a component via a melt pipeline; the melt permeates into the inside of sea sand, and is filled in a component cavity under the action of extrusion force of a screw so as to generate inner pressure; particle impurities in the sea sand are precisely filtered; the entire component has no dead angle after the melt is hindered by resistance; each spinneret orifice can bear equal pressure so as to ensure that the melt uniformly flows towards each spinneret orifice under a high pressure state, ensure the stability and uniformity of melt quality and make the fiber uniformity better without a broken silk or a silk head.

Description

technical field [0001] The invention belongs to the technical field of regenerated polyester fiber production, and in particular relates to a spinning device in the regenerated polyester fiber preparation process. Background technique [0002] Existing high-pressure jet spinning equipment for preparing recycled polyester fibers, such as figure 1 As shown, by the component head cover 3, the pressure plate 5, the distribution plate 6 and the spinneret 7, the pressure plate 5, the distribution plate 6 and the spinneret 7 are fixedly connected under the component head cover 3 through the pressure ring 8, and the melt The inlet 2 is arranged on the side of the assembly headgear 3, and the top of the assembly headgear 3 is provided with a suspension ring 1. Since the raw materials of recycled polyester fibers are waste polyester bottle flakes and waste polyester textile scraps, but the purity and melt fluidity of the waste materials are significantly different from those of the o...
