Technical Field

The invention relates to the technical field of new materials, and particularly relates to a formula of modified polyethylene for cool cloth, a preparation method and application thereof.

Background

With the continuous development of cool cloth, recently, polyethylene becomes a key material of cool cloth, and the modification research on polyethylene is more and more. However, the existing polyethylene mainly has the following disadvantages: 1. the existing polyethylene can only be used for drawing monofilament generally, is relatively thick, is difficult to be made into multifilament and is more difficult to be made into garment materials, and 2, the existing formula is difficult to obtain different color appearances under the condition of keeping the ideal infrared transparency of the polyethylene material, so that the problem to be solved in further practical application is urgently needed. The traditional dyeing method is not suitable, and the common traditional organic dyes have different chemical bonds, so that the common traditional organic dyes can strongly absorb human body radiation in the mid-infrared band, thereby greatly reducing the infrared transmittance. Furthermore, the chemical inertness and lack of polar chemical bonds of polyethylene make it very difficult for chemical dyes to attach to their surfaces.
