preparation example Construction

[0030] 1. Preparation of padding working solution:

[0031] A certain amount of binder and thickener is added to the phase-change microcapsule aqueous dispersion, and the mixture is evenly stirred to prepare a phase-change microcapsule functional finishing agent with a certain viscosity.

[0032] 2. Padding process:

[0033] The yarn is immersed in the microcapsule finishing solution for 1 to 5 hours. After the yarn is fully swollen, the microcapsule not only adheres to the surface of the yarn, but also penetrates into the interior of the yarn.

[0034] 3. Pre-baking and baking:

[0035] The above-mentioned processed fabric is subjected to drying and setting treatment, pre-drying (50-90° C. × 1-2 hours) → baking (110-130° C. × 1-5 minutes). One is to remove moisture, and the other is to fix the microcapsules on the yarn by the adhesive after high-temperature baking, so as to improve the fastness to washing and rubbing.

[0036] 4. Weaving:

[0037] Finished yarns are made ...

Embodiment 1

[0043] Working fluid formula: nano phase change capsule, phase transition temperature 33°C, average particle size 100nm, dosage 95.5%; binder (WX-351), concentration ratio 3%; thickener (HIT), dosage 1.5%.

[0044] Preparation process: After placing the weighed thickener in the container, under stirring, add the microcapsule dispersed emulsion in three batches, continue to stir for 30 minutes, add the binder, continue to stir evenly to make a viscous phase change microcapsule functional working solution.

[0045] Two-dipping and two-rolling process: pure cotton yarn (28.6×3tex); liquor ratio: 1:30, rolling off rate 150%, pre-baking (80°C×2h)→(baking 130°C×2min).

Embodiment 2

[0047] Working fluid formula: nano phase change capsules, phase transition temperature 37°C, average particle size 100nm, dosage 95.5%; binder (WX-351), dosage 3%; thickener (HIT), dosage 1.5%.

[0048] Preparation process: After placing the weighed thickener in the container, under stirring, add the microcapsule dispersed emulsion in three batches, continue to stir for 30 minutes, add the binder, continue to stir evenly to make a viscous phase change microcapsule functional working solution.

[0049] Two-dipping and two-rolling process: pure cotton yarn (28.6×3tex); liquor ratio: 1:30, 100% scrap rate, pre-baking (80°C×1.5h)→(baking 130°C×3min).

Abstract

The invention discloses a method for preparing an intelligent temperature regulating functional yarn, which has the following steps of charging cementing agent and thickening agent into phase-change microcapsule dispersion to intimately mix and obtain phase-change microcapsule functional finishing agent with viscosity, wherein the content of the cementing agent and the thickening agent are respectively 0.5-5% by weight of the finishing agent, the phase-change microcapsule functional finishing agent is finished on the yarn via a double-nip-double-dip or a sizing process, and then obtaining textiles via weave technology. The selected capsule is water dispersion with good surroundings, wherein the capsule size is about 100nm which is only one-tenth or one-percent of the yarn fineness, thereby being capable of greatly improving dosages of the capsules in the yarns, at the same time holding constant raw mechanical property of the yarn, furthermore, the method has the advantages of convenient and flexible processing, good operability and being basically not influence on hand feeling and breathability of fabrics due to adopting the double dip double nip or the slashing process, and the performance test indicates that the finished textile has obvious heat storage and temperature regulating effects.

Description

technical field [0001] The invention relates to textile materials, in particular to a method for preparing an intelligent temperature-regulating functional yarn. Background technique [0002] As a necessity of human life and a symbol of human civilization, clothing is closely related to social progress and the development of science and technology, and develops with the development of the times. Since the 1990s, the development and development of new heat-preserving and temperature-regulating yarns and fabrics has suddenly sprung up. It is a high-tech product full of vitality. Intelligent temperature-regulating yarns and their products can be automatically and reversibly adjusted as the ambient temperature changes. Its own temperature can not only improve the comfort of clothing, but also has high added value and can achieve high benefits. Therefore, in recent years, various new heat-preserving and temperature-regulating textiles have come out one after another, such as far...
