Flexible fabric coatings are expected to remain smooth and firmly attached during stretching, folding and washing.

In production, however, coating manufacturers often find it difficult to improve elasticity without affecting film strength or hand feel.

Flexible fabrics place more stress on the coating

A coating applied to an elastic fabric is repeatedly deformed during use.

If the film is too rigid, it may crack or turn white. If adhesion is insufficient, the coating may separate from the textile surface.

A very soft resin can improve flexibility, but it may also lead to tackiness or weak abrasion resistance.

For this reason, resin selection is less about maximizing one property and more about finding a workable balance.

High solids can improve coating efficiency

Drying remains an important issue in water-based textile coating.

Lower-solids systems introduce more water, which can increase oven demand and limit production speed.

High-solids acrylic resins deliver more polymer at the same wet coating weight. This can support faster film build and reduce the amount of water that must be removed.

The formulation must still maintain suitable viscosity, leveling and application stability.

Substrate differences cannot be ignored

The same coating can behave differently on polyester, nylon, cotton or blended fabrics.

Fiber type, fabric structure, absorbency and surface treatment all affect adhesion and film appearance.

Testing on the actual substrate remains necessary before commercial production.

New resin for flexible textile coatings

Sinograce Chemical has developed a high-solids water-based acrylic resin for fabric coatings requiring strong adhesion and high elasticity.

The product is intended for flexible textile coatings, backing coatings and other applications where the film needs to move with the fabric.

Customers can evaluate the resin according to their substrate, coating process and required performance.
