Abstract

The invention discloses a hot melt adhesive net film product including bamboo carbon fibers, so that the hot melt adhesive net film product has the functions of moisture absorption and air permeability, antibiotic inhibition, ultraviolet resistance, deodorization and adsorption, environmental protection and comfort of the product are enhanced, and performances of the hot melt adhesive net film product are expanded. Meanwhile the invention further discloses a process for preparing the hot melt adhesive net film, thereby ensuring that the bamboo carbon fibers are uniformly distributed in the net film product and the reliability of the product is enhanced.

Description

technical field [0001] The invention relates to a hot-melt adhesive film and a preparation process thereof, in particular to a hot-melt adhesive film added with bamboo charcoal fibers and a preparation process thereof. Background technique [0002] Hot-melt adhesive film is a mesh-like hot-melt adhesive product made of hot-melt adhesive by drawing, laying, and rolling. It has environmental protection characteristics such as breathability, solvent-free, strong viscosity, and water resistance. It can be processed in any specification, and can be operated continuously or intermittently. It is widely used in the bonding of various fabrics, papers, polymer materials and metals. [0003] At present, hot-melt adhesive films are usually divided into PA, PES, TPU, EVA and other hot-melt adhesive films according to their hot-melt adhesive raw materials. These films are used in different fields due to their own characteristics of hot-melt adhesive materials. . With the development of...
