Embodiment 1

[0019] The production process of a kind of two-color knitted composite wrinkled fabric involved in the present embodiment comprises the following steps:

[0020] 1) Preparation of colored polyester filaments: pre-crystallize and dry polyester chips, and melt and extrude the dried polyester chips, thermoplastic polyurethane, monoisocyanate, dispersant, and color masterbatch to form polyester filaments.

[0021] The thermoplastic polyurethane, monoisocyanate and dispersant account for 5%, 1% and 2% of the weight of the polyester chips respectively.

[0022] The color masterbatch contains 30% pigment, 10% ethylene acrylate copolymer, 5% dispersant, and the rest is carrier resin. The dispersant used is polyvinyl acetate, which contains ester groups to make polyester chips, thermoplastic polyurethane, and monoisocyanate well dispersed and mixed. And it contains vinyl groups, which can be well miscible and dispersed with the ethylene acrylate copolymer in the masterbatch.

Embodiment 2

[0030] The production process of a kind of two-color knitted composite wrinkled fabric involved in the present embodiment comprises the following steps:

[0031] 1) Preparation of colored polyester filaments: Pre-crystallize and dry polyester chips, and melt and extrude the dried polyester chips, thermoplastic polyurethane, monoisocyanate, dispersant, and color masterbatch to form polyester filaments.

[0032] The thermoplastic polyurethane, monoisocyanate and dispersant account for 2%, 0.5% and 1% of the weight of the polyester chips respectively.

[0033] The color masterbatch contains 20% pigment, 5% ethylene acrylate copolymer, 2% dispersant, and the rest is carrier resin. The dispersant used is polyvinyl acetate, which contains ester groups to make polyester chips, thermoplastic polyurethane, and monoisocyanate well dispersed and mixed. And it contains vinyl groups, which can be well miscible and dispersed with the ethylene acrylate copolymer in the masterbatch.

Abstract

The invention discloses a production process of a double-color composite wrinkled knitted fabric. The production process comprises the following steps: 1) preparation of colored polyester filament yarn: pre-crystallizing and drying polyester chips, and carrying out melt extrusion on the dried polyester chips, thermoplastic polyurethane, monoisocyanate, a dispersing agent and color masterbatch to form the polyester filament yarn; 2) preparation of wrinkled knitted fabric; 3) preparation of single-sided tatting-imitating seersucker fabric; (4) compounding: compounding the wrinkled knitted fabric prepared in the step 2) and the single-sided tatting-imitating seersucker fabric prepared in the step 3) by adopting a hot melt adhesive net film, and enabling the wrinkled knitted fabric to be in a flattened state during compounding. According to the production process of the double-color composite wrinkled knitted fabric, thermoplastic polyurethane and monoisocyanate are added into the prepared colored polyester filament yarn, so that the resilience of the colored polyester filament yarn can be improved, and the prepared double-color composite wrinkled knitted fabric is stable in wrinkling style and good in reproducibility.

Description

technical field [0001] The invention relates to the technical field of knitted fabrics, in particular to a production process of two-color knitted composite wrinkled fabrics. Background technique [0002] Knitted wrinkled fabrics are more and more popular with consumers due to their special three-dimensional visual effects. However, some knitted wrinkled fabrics are now either wrinkled mechanically or through special jacquard structures. However, the above methods The knitted wrinkled fabric produced has defects such as complicated process and high production cost. [0003] In addition, it is also possible to achieve the purpose of fabric wrinkling by adding spandex or using spandex-covered yarn to control shrinkage. However, due to the elasticity of spandex or spandex-covered yarn, it is difficult to control the weaving tension. Finally, it is not easy to guarantee the quality of the cloth surface. In addition, the elasticity of spandex or spandex-covered yarn itself will...
