Dow Introduces Breakthrough Polypropylene Resin for Production of Remarkably Soft, Cloth-Like Nonwoven Textiles
Wednesday 13. April 2011 - The Dow Chemical Company (NYSE: Dow) today introduced DOW SOFT TOUCH Polypropylene (PP) Resin, a family of breakthrough single-pellet resin solutions for the efficient production of mono-component spunbond nonwoven fabrics that exhibit remarkable softness and drape while retaining the physical properties of polypropylene nonwoven fabrics.
Responding to consumer desire for softer fabrics in absorbent hygiene products and medical nonwovens, Dows first product in the new DOW SOFT TOUCH PP Resin family, DC 543 Developmental Polypropylene Resin, was unveiled at INDEX 11, a global trade fair for the nonwovens industry taking place in Geneva, Switzerland from April 12-15, 2011.
The health and hygiene industrys drive to identify softer nonwoven fabrics has triggered the development of a range of raw materials solutions in recent years, from resin additives, mechanical alteration, and blends to bi-component fibers. Each solution offers some degree of softness, but often at only marginal perceptibility, higher cost or increased operational complexity.
Nonwoven fabrics made with DOW SOFT TOUCH PP resin overcome these challenges through a single pellet solution that can be used in existing mono-spunbond lines. The new resin solutions offer noticeably improved comfort for end-users of nonwoven products in the form of tactile softness, improved drape (ductile softness) and a reduction in noise intensity.
In recent sensory testing, highly trained panelists easily perceived the improved softness attributes of nonwoven fabrics made with DOW SOFT TOUCH PP resin and gave them more favorable ratings than fabrics made with homopolymer polypropylene. Handle-o-Meter testing, an industry accepted method of measuring softness, further confirmed the panel results.
DOW SOFT TOUCH PP resin also offers key physical properties that until now have been a challenge to achieve in combination with breakthrough softness. The resin has a low bonding temperature and a broad bonding window for processing efficiency and flexibility. It also offers tensile properties comparable to polypropylene and excellent abrasion resistance for low linting and fuzzing in the final nonwoven article.
“Dow is committed to meeting brand owner and converter needs by closely monitoring global trends and constantly developing new products to address market needs,” said Carlos Ruiz, global market director for Dows Health & Hygiene business. “The new single-pellet DOW SOFT TOUCH PP resin also enables the production of excellent, cost-effective nonwoven fabrics in mono-spunbond lines.”
To help brand owners and converters satisfy their sustainability objectives, nonwoven webs formed with DOW SOFT TOUCH PP resin can be recycled back into mainstream production, thereby reducing operational waste. Additionally, with a lower bonding temperature than homopolymer polypropylene, the resin also contributes to reduced energy consumption during processing.
Dows stand at INDEX 11 is #1540.
