“Today’s technical textiles and nonwovens applications range from filtration media to aircraft interiors and are diverse, demanding, highly specialized, and rapidly evolving,” said Michael Gilbert, general manager, Innovative Plastics. “SABIC is helping to meet growing demand for these products by focusing on the ever-changing needs of our customers in this space and meeting their specific requirements by collaborating with them to develop new fiber technology solutions. These solutions represent a significant value-add to an array of fabric systems and continue to show how our resins provide customers with innovative, new options for product differentiation and tailored performance.”
Multiple Solutions for Woven and Nonwoven Textiles
Ultem Fiber Based on Ultem Resin
SABIC’s Ultem resin is an amorphous thermoplastic polyetherimide (PEI) resin that offers outstanding elevated thermal resistance, high strength and stiffness, and broad chemical resistance. This work-horse technology features its signature flame, smoke and toxicity (FST) performance;
Ultem fiber is based on Ultem resin and also provides these properties along with exceptional light weight and excellent aesthetics for many flame retardant (FR) applications in aerospace, rail and home fabrics – including carpets, kick panels, seating and wall coverings, curtains and bedding materials. This fiber can also be used to create a variety of non-woven solutions for the transportation industry, including insulation blankets, wicking felt, seat fire blockers and cushions.
Woven fabrics incorporating Ultem fiber, such as those used in safety and protective workwear, can be colored using conventional exhaust dyeing techniques, resulting in exceptional colorfastness and resistance to ultraviolet (UV) light. For example, Japan Wool Textile Company, a division of NIKKE Group, is blending Ultem fiber with wool and other materials to produce yarn, fabrics and garments that offer a unique combination of comfort and protection, including permanent, non-halogenated flame retardance and excellent UV resistance.
Fibers made from Ultem resin are softer and less abrasive than those made from conventional aramids, giving converters better control over system costs by reducing the stress on textile machinery. Plus, PEI fiber can be blended with other natural and synthetic fibers to provide OEMs with an optimal balance of performance and economics.
Valox and Valox iQ* Resins and Fiber
The Valox family of thermoplastic polyester resins are semi-crystalline materials based on polybutylene terephthalate (PBT) and/or polyethylene terephthalate (PET) polymers. Valox iQ resins are created with PBT-based polymers derived from up to 60 percent post-consumer plastic waste to promote environmental responsibility and require less energy and yield less carbon dioxide (CO2) during manufacturing than traditional resins.
Valox resins enable soft yet resilient monofilaments, staple fibers and continuous filament yarns for woven and nonwoven fabrics. Valox fiber, derived from Valox resin also provides excellent dyeability and colorfastness, extremely favorable stretch and recovery when compared to PET resin, and high chemical resistance. This fiber can be used to develop filtration fabrics, performance apparel such as swimsuits, stretch fabrics and monofilaments.
Valox iQ 2205HV resin is used as a critical additive to textiles to provide improved permanent stain resistance (vs. standard PET fiber) and strong, consistent color, and to maximize post-consumer recycle content. Valox iQ 2205HV resin is also highly effective in dispersing pigment throughout the polymer melt to produce consistent, vivid colors – what the flooring and carpet industries call “color pop” – with lower loadings of expensive colorants.
Lexan Resin and Fiber
Lexan polycarbonate (PC) resin is an amorphous engineering thermoplastic characterized by outstanding mechanical, optical, electrical and thermal properties. The Lexan portfolio provides broad design versatility through its wide range of viscosities and product options such as: environmentally conforming FR, scratch resistance, toughness, heat resistance, weatherability, biocompatibility, optical quality, and compliance with stringent Food and Drug Administration (FDA) and United States Pharmacopeial (USP) requirements.
As a fiber, with its inherent anti-static properties and excellent loft, Lexan resin can be used in the development of filtration fabrics for industrial air filtration and automotive cabin air filters.
Noryl Classico Resins as Fibers
The Noryl Classico family of modified polyphenylene ether (PPE) resins combine the inherent benefits of PPE resin – high heat resistance, good electrical properties, excellent hydrolytic stability and the ability to provide non-halogenated FR solutions – with excellent dimensional stability, good processibility and low specific gravity.
Noryl Classico fibers offer a good balance of mechanical and chemical properties, and target a wide variety of fiber applications where insulative and electrical properties are important, such as filtration media, battery separators, electrical fabrics, industrial fabrics and high-performance papers.
