Cool-feeling alkali-soluble chinlon 6 master batch and fiber and preparation method of application of cool-feeling alkali-soluble chinlon 6 master batch and fiber

The invention relates to the technical field of chemical fibers, in particular to a cool-feeling alkali-soluble chinlon 6 master batch and fiber and a preparation method of application thereof.The preparation method comprises the steps that chinlon 6 powder, alkali-soluble modified low-melting polyester chips, pre-dispersed composite jade powder and a dispersing agent are smashed and ground respectively and then placed in a high-speed mixer to be mixed, and mixed powder is prepared; the mixed powder is subjected to melting plasticizing, screw conveying and shearing, water-cooling pelletizing, vibration screening and forced air drying, and the cool-feeling alkali-soluble chinlon 6 master batch is prepared; the prepared cool alkali-soluble chinlon 6 master batch is prepared into cool alkali-soluble chinlon 6 fiber, and then the cool alkali-soluble chinlon 6 fiber is used for preparing the cool alkali-soluble chinlon 6 cloth. Compared with the common chinlon 6 fiber, the chinlon 6 fiber prepared by the invention
