AI Technical Summary

Technical Problem

Existing charcoal linings are prone to poor adhesion and unevenness after sewing, affecting the appearance of the garment and resulting in poor practicality.

Method used

The double-point coating hot melt adhesive technology is adopted, using black carbon lining as the base layer, and coating it with resin pillars made of acrylic thermosetting resin and hot melt adhesive powder. The resin pillars and hot melt adhesive are distributed alternately, and the shape and distribution of the coating are controlled by screen printing process to avoid hot melt adhesive penetration and local insufficient adhesion.

Benefits of technology

It improves the fit between the charcoal lining and the fabric, as well as the smoothness of the garment, avoids appearance defects caused by poor stitching, enhances bonding strength and durability, and improves production efficiency.

Abstract

This utility model relates to the field of textile and lining production and processing technology, and discloses a double-point coated hot-melt adhesive charcoal lining, including a base layer. A pre-reserved groove is formed on one side of the base layer. Resin pillar one and resin pillar two are coated on the side of the base layer near the pre-reserved groove. Colloidal powder one and colloidal powder two are disposed on the side of resin pillar one and resin pillar two away from the base layer. Resin pillar one and colloidal powder one correspond one-to-one, and resin pillar two and colloidal powder two correspond one-to-one. This double-point coated hot-melt adhesive charcoal lining uses a double-point coating method to coat the charcoal lining surface with hot-melt adhesive. The base layer is a thermosetting material to prevent reverse adhesive penetration when bonding with the fabric. The surface hot-melt adhesive can partially penetrate the fabric fibers during bonding, resulting in a good bond with the fabric. This avoids the need for sewing, preventing insufficient tightness and flatness of the fit, and avoiding the negative impact of poor sewing on the garment's appearance.
