Embodiment 1

[0026] This example is cotton knitted fabric, 32S yarn, weight 220g / m 2 .

[0027] (1) Pretreatment process and formula: first add penetrating agent, then add caustic soda and sodium silicate in 2 times, then raise the temperature to 60°C, add hydrogen peroxide in 2 times, keep warm for 5min and then raise the temperature at a heating rate of 1.5°C / min to 90°C, keep warm for 30min, then lower the temperature to 88°C at a rate of 2°C / min and wash with water. The pretreatment formula is NaOH: 2g / L, hydrogen peroxide: 8g / L, stabilizer (sodium silicate): 6g / L, penetrant (fatty alcohol polyoxyethylene ether, RUCOWET RDA produced by Rudolph Company): 3g / L L.

[0028] (2) Dyeing process and formula: Add leveling agent and penetrating agent at 40°C, mix evenly, add dye, and finally add NaCl in 2 times, raise the temperature to 70°C at a heating rate of 1.5°C / min, keep warm for 40min, then add Fix the color with soda ash for 40 minutes, then reduce to room temperature and wash twice...

Embodiment 2

[0033] The printing slurry is made of 78% polyacrylic printing former paste BT-PTF (Dongguan Baishide Chemical Company), 20% water-based polyurethane adhesive, 2% temperature-sensitive color-changing coating (temperature-changing coating BT-WB, purchased from Dongguan Best Chemical Co., Ltd.) mixed uniformly. In step (4), the drying temperature is 120°C, the baking temperature is 170°C, and the baking time is 150 seconds. The rest of the operations were the same as in Example 1, and an intelligent temperature-sensitive color-changing fabric was prepared.

Embodiment 3

[0035] After pigment printing, the drying temperature is 100°C, the baking temperature is 180°C, and the baking time is 60 seconds. The rest of the operations are the same as in Example 1, and the intelligent temperature-sensitive color-changing fabric is prepared.

Abstract

The invention discloses an intelligent temperature-sensitive color-changing fabric and a processing method thereof. The processing method comprises the following steps: using a flat screen printing process, applying the slurry to the dyed cloth surface, drying, and baking; wherein, the raw material formula of the slurry includes the following components: Original printing paste: 75%-78%, binder: 20%, temperature-sensitive color-changing paint: 2%-5%; the percentage is the mass percentage; the viscosity of the slurry is 7000-10000mPa s; the drying temperature is 100 ℃~120℃, the baking temperature is 170℃~180℃, and the baking time is 60s~150s. The intelligent temperature-sensitive color-changing fabric prepared by the processing method of the invention is comfortable to wear, and its temperature-sensitive color-changing performance remains unchanged after several times of washing, and has wide application prospects.

Description

technical field [0001] The invention relates to the field of materials, in particular to an intelligent temperature-sensitive color-changing fabric and a processing method thereof. Background technique [0002] With the development of textile technology, textiles have broken through the original scope of heat preservation and beautification, and are gradually becoming functional and intelligent. The development of functionality and intelligence has injected new vitality into the development of clothing, bringing people more novelty and fun while being beautiful. Can greatly increase the added value of the product. [0003] Currently developed intelligent textiles, the realization of its intelligent function is mainly through the following three ways: (1) some intelligent fibers or ordinary fibers are modified and woven into fabrics or woven into fabrics, so that the fabrics have characteristics (2) ) Microencapsulate certain smart substances, and process them on fabrics by...
