Application method of pure cotton flame retardant special agent
The application method of pure cotton flame retardant mainly depends on the type of flame retardant, the type of fabric, and the performance requirements of the final product. Here are several common application methods:
1. Dip rolling method:
Process flow: The fabric is immersed in a flame retardant solution → the excess solution is removed by rolling with a roller → drying → baking (some flame retardants are required)
Advantages: Simple operation, high production efficiency, suitable for various fabrics.
Disadvantages: The amount of flame retardant used is relatively large, which may affect the texture of the fabric.
Application: Widely used in flame retardant treatment of pure cotton fabrics.
2. Coating method:
Process flow: Apply flame retardant onto the surface of the fabric → Dry → Cure (some flame retardants require it)
Advantages: Low usage of flame retardants and minimal impact on fabric feel.
Disadvantages: Complex process, low production efficiency, and possible impact on fabric breathability.
Application: Commonly used in situations where high flame retardant performance is required and the original feel and breathability of the fabric need to be maintained.
3. spray method:
Process flow: Spray flame retardant solution on the surface of the fabric → Dry
Advantages: Flexible operation, suitable for local flame retardant treatment.
Disadvantages: Uneven distribution of flame retardants may affect the appearance of fabrics.
Application: Commonly used for temporary flame retardant treatment in stage scenery, exhibition decoration, etc.
4. Other methods:
Microcapsule method: The flame retardant is encapsulated in microcapsules and then applied to the fabric through methods such as dipping, coating, etc.
Graft copolymerization method: graft copolymerization of flame retardant monomers with cotton fibers to make the flame retardant a part of the fibers.
Nanotechnology: Utilizing nanotechnology to uniformly disperse flame retardants in fabrics, improving flame retardant efficiency and durability.
Choosing the appropriate application method requires consideration of the following factors:
Types and properties of flame retardants
Types and structures of fabrics
Performance requirements for the final product
Production costs and equipment conditions
There are various application methods for pure cotton flame retardants, and it is necessary to choose the appropriate method according to the specific situation. With the advancement of technology, new application methods continue to emerge, providing more options for flame retardant treatment of pure cotton fabrics.
