US’ Michelman expands water-based technologies for technical textiles

November 24, 2021 - United States Of America

Michelman, US-based developer of materials for coatings, printing, and packaging, has expanded its surface modification solutions for technical textiles. It is helping to improve the performance and functional behaviour of technical textiles in construction, ballistic, medical and hygiene, automotive, filtration media, pre-preg, and consumer products.

Unyte is Michelman’s versatile family of water-based technologies that help achieve advanced form and function in both woven and nonwoven materials used in the design of technical textiles and pre-preg fabrics. These solutions enhance textile products’ performance by improving adhesion, binding, slip, processability, and chemical and heat resistance, Michelman said in a press release.

Unyte Bind offers multiple solutions that improve fibre-to-fibre adhesion. Unyte Heat solutions provide heat resistance during primary and secondary processing and impart heat resistance in end-use applications. Unyte Glide increases lubricity and slip and facilitates tow spreading of fibres in technical textile production. This grade of products is also used as oversizing to improve release, drape, and fabric processability.

Unyte Grip promotes the adhesion between fibres and polymeric matrices, helping to improve various functional or mechanical properties. Unyte Slip helps prevent fabrics, nonwovens, and pre-pregs that need to be stacked or rolled without sticking together. Unyte Resist products are designed to provide excellent wet-out and moisture/chemical resistance to fabrics, wovens, and nonwovens, according to Michelman.

“Our proven expertise in formulating water-based surface treatments, including sizing, binders, and film formers, strengthened by our understanding of end-use applications, provides technical textile manufacturers a set of sustainable solutions offering various functionalities that can be applied at the fibre level or as an overtreatment to the textile,” Jared Stonecash, global marketing manager for fibres and composites, Michelman said in a statement.
