Non-woven binders

Styrene-butadiene copolymers for caipet backing, upholstery backing, paper coating, paints and for non-woven binders,... 

Nonstabilized foams are referred to as froths froth-bonded fabrics are similar in properties to some satnration-bonded nonwovens. Typical foams nsed as non woven binder solutions have a consistency similar to shaving cream. Application methods include knife-edge layering onto a horizontal web snrface followed by vacuum penetration, and saturation and penetration of a vertical web snrface... 

While PVOH and the vinyl acetate (co)polymers would not typically be considered to be compatible, the grafting achieved during polymerization and the resultant morphology yields useful and compatible compositions. The presence of PVOH yields good adhesion to cellulosic based substrates for wood glue, non-woven binder, and paper based packaging applications. The miscibility of PVOH with cellulose has been demonstrated, providing a rationale for the excellent adhesion [30]. 

Applications for PHA can be found in areas of flushable, non-wovens, binders, films, flexible packaging, thermoformed articles, coated paper, synthesis paper, and coating systems (www.nodax.comV However, current PHA production cost is still too high to satisfy such low added value demand. Therefore, we believe that high added value application should be more realistic. As PHA are biodegradable, and possibly biocompatible, their application as biomaterials or tissue engineering materials should be very attractive.

Can be applied to non-wovens by incorporating it with the acrylic or latex binder. 

FACEGARD A can be applied to non-woven acrylic blankets as a permanent binder. 

INTEX BINDER 273 produces a film that does not yellow under normal drying and curing temperatures. The film also has good tensile strength and can even be applied as a binder for non-wovens. The cross-linked film is also quite resistant to washing and to dry-cleaning.

A majority of the acrylic emulsion polymers used in textile and non-woven applications are crosslinked or cured after film formation to provide wet stroigth, solvent resistance and durability to laundering and dry cleaning. As with architectural coatings binders, the principal monomers used are BA, EA and MMA,... 

The polyester fibers have high shrink properties, which make them useful in fiber applications where crimp retention or high bulk is desired. Typical applications are in carpet yams, hi-loft non-woven fabrics used as interlinings, cushioning media, and filtration media, as well as in specialty yams for weaving and knitting. The fibers have a lower melting temperature compared to PET, which makes them useful as binder fibers in non-wovens, particularly in combination with PET homopolymer fibers. 

Non-woven Fabrics In latex form it is used as a binder in the production of non-woven fabrics both for industrial and domestic use. 

Chopped Strand Mat (CSM)—Non-woven mat in which the glass fibre strands are chopped into short lengths of approximately 50 mm and fairly evenly distributed and randomly orientated. The mat is held together by a binder. 

P(l) CFM may be used as an alternative to CSM. Properties and application potential are similar to CSM. CFM is a non-woven material similar to chopped strand mat except that the fibres are swirled at random and are continuous. The swirled strands are interlocked with a binder. The user should check with the supplier on the compatibility of the binder for a specific resin system. 

The reinforcement used is generally a combination of uni directional roving and random mat (continuous filament mat). This combination provides a reasonably optimised set of properties in the longitudinal and the transverse directions respectively. Other reinforcement types may be used, including woven roving, chopped strand mat (nonsoluble binder), needled mat and multi-axial non-woven. 

A non-woven carbon fabric is made from fibers held in position by a binder, which can include melt bonding powders and meltable fibers, thermosetting resins and thermoplastic... 

These are produced by converting a loose web or fleece of fibres into an integral structure. To stabilize the construction of most non-wovens, an adhesive is applied either as a polymer dispersion/latex (binder) or incorporated in the fleece as a thermoplastic (fusible) material. 

Adhesives are widely used in the textile industry as shown in Table 1. If sizes and tyre cord dips are excluded, approximately 65% are used in carpet backing (mostly styrene-butadiene rubbers). Other major uses of adhesives are in non-wovens as binders (15%), in fabric backing (8%), in flocking and laminating (8%) and in fusible interlinings (2%). 

Polyvinyl alcohol solutions are also used as adhesion binders for non-woven fabrics, screen-printing, ferrites, ceramics and some building materials. In powder form, it is also an effective binder for finely divided powders, such as pigments. Mixtures of low dp polyvinyl alcohol with ethylene glycol, however, have low adhesion to substrates and are used as peelable coatings for metals and plastics for protection during storage and transport.
