Abstract

The invention relates to the technical field of textile, and discloses a production method of a double-color wool-like polyester fiber. The production method includes the steps: 1) converging monofilaments A and monofilaments B, and sequentially performing drafting, deformation cooling, false twisting, drafting and sizing; 2) sequentially performing drafting and filament guiding on monofilaments C; 3) further compounding the monofilaments A, the monofilaments B and the monofilaments C at a wire stitching machine, and sequentially performing drafting, oiling and winding to obtain a finished product. The monofilaments A and the monofilaments B are provided with special-shaped section polyester pre-oriented yarns with different dyeing performances, and the monofilaments C are provided with circular section high-shrinkage polyester FDY filaments. A fabric woven by the double-color wool-like polyester fiber prepared by the method is post-treated and dyed, contraction effects are obvious, double-color effects are remarkable, lodging of fabric cannot be easily generated when the fabric is sanding, hand feeling is thicker and fuller, and wool-like effects are vivid.

Description

technical field

[0001] The invention relates to the technical field of textiles, in particular to a production method of two-color wool-like polyester fibers. Background technique

[0002] At present, the wool-like products of polyester fiber on the market are mostly composed of two or more "three different" polyester filaments of different deniers, different cross-sections, and different shrinkages. The largest market share is still POY in the spinning section. +FDY one-step co-spun blended yarn, this method is favored by many manufacturers because of its large output, less land occupation, less labor and low energy consumption, but this production method is not flexible enough compared to the two-step method , the two-step production can be compounded on the flat drawing machine, the texturing machine and the winding machine, the two-step production can realize the flexible combination of various raw materials to meet the different needs of customers, and the compounding o...
