What are the components of spunlace nonwoven fabric?
The composition of spunlace nonwoven fabric mainly includes fibers and binders. Spunlace nonwoven fabric is a type of nonwoven fabric that intertwines fibers together through high-pressure water jets and uses binders to secure the fiber structure. The following are common components of spunlace nonwoven fabric:
1. Fibers: Spunlace nonwoven fabric can use various types of fibers, including natural fibers and synthetic fibers. Common natural fibers include cotton, wood pulp, and flax fibers. Synthetic fibers can be polyester fibers, polyamide fibers (nylon), or polypropylene fibers, among others. Different types of fibers can be chosen based on the requirements of the final product to provide different performance and characteristics.
2. Binders: Binders are a crucial component of spunlace nonwoven fabric as they help to secure the interlocked fiber structure in the fabric. Commonly used binders include hot melt adhesives and chemical binders. Hot melt adhesives are thermoplastic materials that become liquid at high temperatures and solidify into a bond upon cooling. Chemical binders, on the other hand, cure through chemical reactions to firmly bond the fibers together.
In addition to fibers and binders, spunlace nonwoven fabric may also contain other additives to enhance its performance or provide specific functionalities. For example, antistatic agents can be used to produce antistatic nonwoven fabric, and antimicrobial agents can be used to create antimicrobial nonwoven fabric.
To summarize, spunlace nonwoven fabric is primarily composed of fibers and binders. Fibers can be natural or synthetic, and binders are used to secure the fiber structure. Other additives can be included as needed to enhance performance or provide specific functionalities.
