Composite sponge is the bonding of sponge and a layer of cloth or leather.

Composite sponge process requirements:

1. Flame bonding (bonding without glue): the foam body is used as a bridge and it is melted and bonded with other materials by flame spraying. The laminated composite product has the characteristics of strong integrity, soft feel, washable and dry cleaning, environmental protection and not easy to crease.

2. Hot-melt adhesive compounding: This process adopts OEKO-TEX CLASS II glue compounding. The fabric made with this glue fits the foam and is washable.

3. Ordinary foam glue: ordinary glue in the market with cheap price.

Composite sponge has many uses and the composite processing of raw materials will be determined according to the use. Composite sponge is a post-treatment process in the deep processing technology of composite fabrics. Flame composite relies on the adhesion of the sponge between the two composite fabrics to bond the two fabrics together. The sponge has the characteristics of heat preservation, heat insulation, sound absorption, shock absorption, flame retardant, anti-static and good air permeability. Therefore, composite sponges are widely used in various industries, such as: automobile industry, battery industry, cosmetics industry, bust underwear manufacturing industry and furniture manufacturing industry.

  For composite sponge products, flame composite sponge is more environmentally friendly than glue composite sponge based on the same sponge and fabric and the glue will contain volatile harmful substances. The flame composite sponge also increases the tear resistance of the sponge, it has the advantages of being clean and environmentally friendly, soft and comfortable, flat and wrinkle-free and high fastness to fit. The composite sponge also has good barrier properties and water resistance, it can be resistant washed and dry cleanable as well.
