Description

Technical Field

[0001] The invention belongs to the technical field of textile whole product development, and particularly relates to a processing method of intelligent temperature-regulating woven fabrics. Background Art

[0002] The pure cotton fabrics on the market now cannot meet the needs of consumers for wearing in alternating hot and cold environments. When the human body is in an alternating hot and cold environment, the body will feel uncomfortable due to the lag in the body's regulatory mechanism. Most of the popular thermostatic textiles on the market are made of phase change fibers. Phase change materials are added during the spinning process. After the spinning, the thermostatic materials are enclosed in the middle of the fiber, which greatly weakens the thermostatic performance. Summary of the invention

[0008] (3) Pretreatment;

[0009] (4) Drying treatment to obtain the intelligent temperature regulating woven fabric.

[0010] The fabric pretreatment in step (1) is to subject the pure cotton grey cloth to the processes of singeing, desizing, scouring, bleaching, mercerizing, dyeing (or whitening, or printing) to produce a semi-finished pure cotton fabric.

[0014] Preferably, the fatty alcohol polyoxyethylene ether compound in step (2) is RAYCLEAN WA-MZ produced by Zibo Lurui Fine Chemical Co., Ltd.

[0015] In step (2), the pH value of the working solution is adjusted to 5-6 by the neutralizing acid.

[0016] In step (2), the rolling rate is controlled to be 65-70%.

[0017] The pretreatment temperature in step (3) is 40-60°C.
