Polypropylene Homopolymer for Production of Fine Denier Staple Fibres for Nonwoven Thermobonded Fabrics. Product Description: • Fabrics made with Parslen ZH554N are characterized by softness, textile-l ike appearance and high tear resistance. • In comparison with standard Polypropylene types for thermobnding applications, Parslen ZH554N offers some distinct advantages. • The processability with the tong-spinning technology is outstanding, resulting in hig h and uniform fibre quality and less down-time. • Parslen ZH554N gives a broad thermal bonding window, which facilitates start-up and adjustments of the plant. • Parslen ZH554N shows a 20 to 30 % increase in thermal bonding ability. This makes it possible to produce fabrics with a higher tear strength or with tower weight per m2 for the same strength. Application: • The fabrics are particularly suited for the production of fabrics for feminine care products, diapers, incontinence pads, medical disposables, wipes and other applications include filters and fabrics for the automotive, clothing and furniture industry.
