The processing technology of hot-melt yarn usually includes the following steps:
Raw material preparation: choose suitable hot melt adhesive raw materials, usually hot melt adhesive particles or hot melt adhesive film.
Melting: Put the raw material of hot melt adhesive into the melting machine for melting. The melting temperature is usually between 150-200°C.
Processing: Spray or coat the melted hot melt adhesive raw material on a base material such as polyester fiber, and then fix it by cooling and solidifying.
Cutting and winding: the processed hot-melt yarn is cut and wound for subsequent use.
Inspection and packaging: quality inspection of hot-melt yarn, packaging and marking.
During the processing, attention should be paid to maintaining the stability of the melting temperature, controlling the amount of coating and curing time, so as to ensure the quality of the hot-melt yarn. In addition, regular maintenance and maintenance of processing equipment is required to ensure its normal operation and production efficiency.
