Problems solved by technology

[0002] Natural solar terms change in four seasons, and the temperature varies greatly between cold and warm seasons. Simple heat storage and warmth can no longer meet the needs of people to adapt to the environment. Aiming at the weakness of one-way temperature-adjusting fabrics against cold but not heat, textile dyeing and finishing workers hope to find a The two-way temperature-regulating fabric makes it have the characteristics of absorbing heat when the ambient temperature is high and releasing heat when the ambient temperature is low, so as to maintain a relatively constant body temperature; the two-way temperature-regulating fabric fundamentally changes the wearing performance of the original fabric , greatly improving the comfort and environmental temperature adaptability of clothing, with high wearing value and wide application fields
[0003] Among them, the reasonable selection of phase change materials is the key technology of this product, which plays a decisive role in the temperature adjustment effect of the fabric. However, the phase change temperature of existing phase change materials is too high to meet the needs of existing products.
