Common Types of Hot-Melt Adhesives<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>PA (Polyamide \/ Nylon Adhesive)<\/strong>: Most widely used, offering excellent dry-cleaning resistance, a soft handfeel, and a moderate bonding temperature.<\/li>\n\n\n\n<li><strong>PES (Polyester Adhesive)<\/strong>: Features outstanding wash resistance, making it exceptionally suitable for workwear or outdoor apparel that requires rigorous industrial laundering.<\/li>\n\n\n\n<li><strong>HDPE (High-Density Polyethylene Adhesive)<\/strong>: Offers relatively low cost, primarily used for standard non-woven interlinings.<\/li>\n\n\n\n<li><strong>EVA (Ethylene-Vinyl Acetate Copolymer)<\/strong>: Features a lower melting point and fast bonding speed, but has weaker high-temperature and wash resistance.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">2. Coating Forms and Processes<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Scatter Coating (Powder Scatter)<\/strong>: Hot-melt adhesive powder is scattered directly onto the base fabric and heat-cured. The adhesive dots are randomly distributed with a heavier handfeel, mostly applied in non-woven interlinings or mid-to-low-grade woven interlinings.<\/li>\n\n\n\n<li><strong>Double-Dot Coating<\/strong>: An advanced international process. A layer of base paste (undercoat) is first printed onto the base fabric, followed by a layer of hot-melt adhesive powder superimposed on top.<\/li>\n\n\n\n<li><strong>Core Advantages of the Double-Dot Process<\/strong>\uff1a\n<ul class=\"wp-block-list\">\n<li>Completely prevents hot-melt adhesive from bleed-through (strike-through) to the front side of the fabric during fusing.<\/li>\n\n\n\n<li>Features highly uniform adhesive dots, a soft handfeel, high peel strength, and exceptional dry-cleaning and washing performance.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>\u886c\u5e03\u4e4b\u6240\u4ee5\u80fd\u4e0e\u9762\u6599\u7262\u56fa\u7c98\u5408\uff0c\u5173\u952e\u5728\u4e8e\u5176\u8868\u9762\u6d82\u5e03\u7684\u70ed\u7194\u80f6\u53ca\u5176\u6d82\u5c42\u5f62\u6001\u3002
