Nonwoven adhesives are specialized bonding agents used to adhere nonwoven fabrics in various applications, ranging from medical products to industrial textiles. Here’s a detailed synthesis of the key information from the search results:
Types and Applications
- Medical Products: Nonwoven adhesives are critical in wound dressings, surgical tapes, and tracheostomy care. They ensure secure adhesion while maintaining breathability and hypoallergenic properties. For example, acrylic glue is commonly used in spunlace non-woven dressings for strong adhesion without skin irritation .
- Industrial and Textile Use: In textiles, adhesives bond nonwoven interlinings for garments, providing structure and durability. Hot melt adhesives and water-based variants are popular here .
Key Properties
- Breathability and Comfort: Medical adhesives are designed to allow air circulation, preventing moisture buildup. Products like Winner Medical’s tracheostomy dressing highlight softness and air permeability .
- Waterproofing: Many nonwoven adhesives, such as those in PU film dressings, offer waterproof features while maintaining flexibility .
- Certifications: Adhesives often comply with ISO, CE, and FDA standards to ensure safety and quality, especially in medical contexts .
Material Composition
- Acrylic and Silicone: These are common adhesive types due to their strong adhesion and biocompatibility. For instance, acrylic glue is used in self-adhesive wound dressings .
- Hot Melt Adhesives: Widely used in nonwoven production for their fast-setting properties and versatility in bonding fabrics like PP spunbond .
Manufacturing and Suppliers
- Chinese Factories: A significant number of manufacturers, such as SHANGHAI ROCKY ADHESIVES and Hangzhou Tuopusi Medical Products, specialize in nonwoven adhesives. They offer customization (OEM/ODM) for medical tapes, dressings, and industrial textiles .
- Testing Standards: Equipment like tensile testers and friction coefficient analyzers ensure adhesives meet mechanical and safety requirements, such as those listed in Labthink’s testing solutions .
Innovation and Trends
- Eco-Friendly Options: Some adhesives emphasize eco-friendly formulations, avoiding toxic additives or incorporating recyclable materials .
- Upcoming Industry Events: Events like IDEA 2025 in Miami highlight advancements in nonwoven technologies, including adhesive innovations .

Requirements for adhesives in non-woven materials
Strong adhesive force:Non woven materials have the characteristics of softness and lightness, but their overall strength is greatly affected by adhesives, so non-woven materials have high requirements for the adhesive performance of adhesives. It is necessary to choose adhesives with good adhesion and water resistance.
High temperature and moisture resistance:In the process of strengthening or post-treatment, non-woven materials need to withstand high temperature and high humidity environments, so the stability and high temperature resistance of adhesives are also critical requirements.
No odor or toxicity:Due to the wide application of non-woven materials in fields that come into direct contact with people, such as furniture, car seats, etc., the environmental friendliness of adhesives is also an important consideration. Choose non-toxic, odorless, and environmentally friendly adhesives.
Good adhesion:The adhesion of non-woven materials is one of the important factors affecting their quality and appearance. The selection of adhesive should enhance the adhesion of non-woven materials and avoid phenomena such as flanging and cracking caused by weak bonding.
Can be widely used:Non woven materials are widely used in different fields, requiring adhesives to have widely applicable characteristics and be able to adapt to multiple materials to ensure the overall stability of the product.
Dongguan Liansheng Non woven Technology Co., Ltd. was established in May 2020. It is a large-scale non-woven fabric production enterprise integrating research and development, production, and sales. It can produce various colors of PP spunbond non-woven fabrics with a width of less than 3.2 meters from 9 grams to 300 grams.
