The color fastness of the fabric can not be increased by continuously increasing the content of the montmorillonite, and at the moment, the mechanical property of the fiber is deteriorated due to the overhigh content of the montmorillonite, so that the phenomena of broken filaments and floating filaments occur in the spinning process, and the improvement of the quality of the fiber is not facilitated.

The preparation of the fabric by using the polyethylene fibers as the cool feeling raw material is not a common material in the field, the cool feeling fabric is mainly realized by physically modifying the fibers by adding materials such as jade powder and the like, and the application difficulty of the cool feeling fabric is that the polyethylene fibers are difficult to dye. The montmorillonite modified fiber dyeing technology is more applied to polypropylene fibers and less applied to the field of polyethylene fibers, and is innovative in dyeing modification of the polyethylene fibers and application of the montmorillonite modified fiber dyeing technology to preparation of cool fabrics.

The montmorillonite modified fiber has a pore effect, the thermal conductivity of the montmorillonite modified fiber is increased under a certain humidity, the montmorillonite modified fiber is beneficial to the rapid heat transfer, and the heat absorption performance of the montmorillonite modified fiber is actually improved.
