Method for preparing hot-melt adhesive net film

Abstract

The invention provides a method for preparing a hot-melt adhesive net film. The method comprises the following steps of: melting a hot-melt adhesive serving as a raw material; squeezing and spinning; heating and crystallizing by infrared light; and solidifying the material to form a net by spraying and the like. The hot-melt adhesive net film with uniform aperture and stable gram weight is prepared by controlling the melting temperature of the hot-melt adhesive, the spinning speed, the speed of a conveying belt, infrared temperature and spray. The steps are continuously finished in a production flow, so that the production efficiency is greatly improved, and the method is suitable for industrial production.

Description

technical field

[0001] The invention relates to a method for preparing a hot-melt adhesive omentum, in particular to a method for preparing a hot-melt adhesive omentum by using polyester hot-melt adhesive and the like as raw materials. technical background

[0002] Hot melt adhesive is known as "green" adhesive due to its solvent-free, pollution-free, fast curing speed and good process performance. It has developed rapidly in recent years. Hot-melt adhesive film is a material with aging resistance, corrosion resistance, good thermal stability, good tensile resistance, burst resistance and good water permeability, so it is widely used in clothing industry, filter materials, shoe leather materials, Packaging materials etc. It is the most promising emerging industry in the textile industry, known as the "new material" in the textile industry.
