Background
In summer, the clothes to be worn have cool, cool and excellent ventilation effects. The cool fabric in the current market is mostly processed by the following two methods: one is realized by adopting ice-feeling raw yarn, and the ice-feeling raw yarn is obtained by adding cool-feeling materials such as jade and the like in the spinning process and then spinning. The method has the advantages that the fabric is good in washability, but the cool feeling materials such as jade are hidden inside the fibers, so that the cool feeling effect is poor after the fabric is contacted with the skin. The other method is to adopt ice feeling auxiliary agents such as mint microcapsules and the like, and the ice feeling auxiliary agents are realized by a later-stage padding mode, but the binding force of the mint microcapsules on the fabric is limited, and in order to increase the binding force, the mint microcapsules need to be fixed at the temperature of more than 100 ℃ after padding finishing, so that the stability of the mint microcapsules is poor, the release is fast, and the cool feeling durability of the fabric is influenced.
