Embodiment Construction

[0034] Below in conjunction with specific embodiment, the present invention will be further explained:

[0035] A polyester waste regenerated fiber spinning process with high process efficiency and improved quality, comprising the following steps:

[0036] (1) Select and sort recycled waste polyester fabrics from different sources and different qualities, and remove non-polyester fabric debris; waste polyester fabrics include clothing fabrics, curtain fabrics, luggage fabrics, and corner polyester fabrics;

[0037] (2) The selected and sorted waste polyester fabrics are sent to the crusher through the conveyor belt for shredding, and waste polyester fabric fragments are obtained; metal detectors are installed before the crusher imports, and when the metal detector detects waste polyester fabrics When the garment cloth or curtain cloth contains metal, the conveyor belt stops;

[0038] (3) Mixing: the waste polyester fabric fragments obtained by shredding in step (2) are transp...

Abstract

The invention relates to an efficient and quality-improved spinning process with recovered fiber of polyester waste cloth. The process comprises the following steps of 1, picking or sorting polyesterwaste cloth; 2, tearing up; 3, dispensing; 4, buffering materials; 5, dense processing; 6, melting; 7, carrying out primary filtration; 8, homogenized thickening; 9, carrying out fine filtration; 10,spinning; 11, cooling forming; 12, oiling pumping; 13, multichannel drafting; 14, crimping; 15, forming; 16, cutting; and 17, packing. The process provided by the invention has higher process efficiency. By using the process provided by the invention, not only the waste polyester fabric before spinning can be prevented from granule making and drying, but also the final quality can be improved. Thewhole process has controllable product viscosity and can save costs.

Description

technical field [0001] The invention relates to a polyester waste cloth regenerated fiber spinning process with high efficiency and improved quality, and belongs to the technical field of polyester waste cloth regenerated fiber spinning. Background technique [0002] Regenerated polyester fiber is made of waste polyester fabric, spinning waste, pulp, discarded PET mineral water bottles, beverage bottles and other discarded PET materials. After mixing, drying, melting, filtering, measuring, cooling and molding, Winding and other process drafting treatment to make products. [0003] At present, the main spinning process of recycled polyester waste cloth includes the following steps: 1. sorting; 2. shredding; 3. pelletizing; 4. drum drying; 5. melting; 6. filtering; 7. spinning. This process route has relatively high requirements on raw materials, and the recycled polyester fabric needs to be dried in pellets. The process is long, the energy consumption is large, and the produ...
