Embodiment 1

[0049] A method for preparing a temperature-sensitive color-changing knitted fabric, comprising the following steps: gray cloth pretreatment→temperature-changing coating printing→finishing after setting;

[0050] 1. Pre-treatment of gray fabric includes:

[0051] (1) Select gray cloth:

[0052] The fabric type is 30S / 1JC plain weave (pearl edge) knitted gray fabric, width 67", 140g / m 2 ;

[0053] (2) Pretreatment process:

[0054] Add 2g / L refining enzyme SK, 4g / L hydrogen peroxide, and 0.5g / L stabilized electrolyte additive EPD to the gray cloth. After mixing evenly, raise the temperature to 95°C and keep it warm for 50 minutes. Then add 0.3g / L glacial acetic acid and cool down to 50°C. ℃, keep warm for 10 minutes;

[0055] (3) Food hair:

[0056] Based on the weight of the fabric, add 0.5% of neutral hair-eating agent (8000L), heat up to 55°C, heat-preserve for 45 minutes, add soda ash 0.5g / L, then heat up to 80°C, heat-preserve for 10 minutes, add neutralizing cleaning...

Embodiment 2

[0080] A method for preparing a temperature-sensitive color-changing knitted fabric, comprising the following steps: gray cloth pretreatment→temperature-changing coating printing→finishing after setting;

Abstract

The invention discloses a manufacturing method of thermochromic knitted fabric. The manufacturing method includes the following steps of gray fabric pretreating, thermochromic coating printing and shaping afterfinish. Bio-polishing processing is carried out on the knitted fabric, the knitted fabric is finished into a semiproduct through moisture absorbing and sweat releasing functions, and thermochromic paint is used for coating printing to obtain the brand-new thermochromic knitted fabric. The fabric has the advantages of being fine and smooth in hand feeling, soft, comfortable and obvious in thermochromic color and having the moisture absorbing and breathable effects, improves weakness of traditional paint print fabric and makes multifunction of ready-made garments better.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a method for preparing a temperature-sensitive color-changing knitted fabric. Background technique [0002] At present, domestic and foreign knitted fabrics mostly use pigment printing process. Most of the finished products printed by this process feel hard, have poor elasticity, poor air permeability, and the fastness to rubbing and dry cleaning are not ideal enough to meet the higher requirements of consumers. In recent years, the market share of knitted apparel fabrics has been increasing, especially the demand for underwear functional fabrics is increasing, which is a new bright spot in the development of apparel knitted fabrics. Consumers have higher style requirements for fabrics, and the theme of printed fabrics is to realize new styles and new features of clothing fabrics. Contents of the invention [0003] The object of the present invention is to provide...
