About Chemical Bonding Nonwoven

• As the name implies, the bonding between fibres is accomplished by adding chemical substances, either in latex, plastic dispersion, polymer emulsion, or in a solvent. Most commonly used bonding agents are in polymer dispersions (emulsion in winter). Some of the polymers can be in powder & paste forms.
• The web is made by dry laid process, both carded & air laid is used.  
• The resin in the emulsion form may be applied by any of the following application techniques for bonding the web.
• Saturation bonding
• Spray bonding
• Print bonding
• Foam bonding
• Knife-over- roll coating
• The types of polymers binders  that are used in dispersion forms are:
• Synthetic rubbers, such as butadiene polymers
• Acrylic polymers , such s acrylates and
• Vinyl polymers & copolymers ( vinyl chloride, vinyl acetate, vinyl ethers, & vinyl esters)
• Other material include polyurethanes & silicon compounds

• The chemical & physical properties of the polymers dispersion, such as particle size, pH, solid content, viscosity, and the degree of cross-linking have a significant influence on the mechanical & physical properties of the fabrics. Carded or garneted resin bonded fabrics form the largest single group of the nonwoven fabrics produced in the world.
