Textile Market:
How PBT Helps to Meet Industry Requirements on Fuctionality
The two main features of the textile market are internationality and intense competition. In addition the industry requirements are continually increasing: in the apparel sector, greater emphasis is being placed on functionality – for example textiles must be rainproof yet breathe; industrial textiles like drying belts for papermaking, or screens for filtration technology are having to meet ever more demanding specifications for temperature, chemical and wear resistance. Legislative requirements for recycling end products and materials also affect the material selection. For example, in automotive interiors, single material systems for components such as seats are rapidly gaining importance. To meet these challenges innovative solutions can often only be realized by using high performance engineering thermoplastics.

Due to a wide range of melt viscosities, high quality PBT can be formed by various common technologies to manufacture meltblown and spunbond nonwovens, monofilaments, multifilaments and staple fibers. Successful commercial applications made from these polymers can be found in automotive, industrial, medical, filtration and clothing textiles.

Thermoplastic polyesters for a wide range of technologies:

	Filaments	Fibers	Nonwovens
Celanex® PBT Grades	2000, 2002, 2003	2000	Meltblown: 2008 Spunbond: 2000, 2025

Filaments: Soft & Flexible
Soft and flexible monofilaments made from Celanex PBT can be used in tooth- or paint-brush bristles. In the industrial textile sector, woven filter screens and drying belts such as those used in the paper and food industries provide an exceptionally difficult technical challenge. With its distinctive property profile, Fortron PPS is a good choice for the production of high tenacity mono- and multifilaments with good toughness. The belts woven from these filaments permit higher productivity, e.g. in paper manufacture, because of the excellent resistance of Fortron PPS to chemicals, high temperatures and hydrolysis.

Fibers: Good Stretch & Comfortable Fit

		Staple fibers have an exceptionally diverse range of applications. They are used primarily as spun yarns or binder fibers in apparel and household textiles. Celanex PBT 2000 has been used successfully for many years as a textured, elastic spun yarn in apparel textiles such as outerwear and sportswear.
The elasticity of our PBT ensures good stretch properties and a comfortable fit. The material does not crease easily, breathes and is skin compatible. Staple fibers and binder fibers made from Celanex PBT can be used in seat upholstery.

Nonwovens: PBT a good option for the thermal and acoustic insulation

Ticona also supplies thermoplastics well suited for the production of spunbond, meltblown and staple-fiber nonwovens, which can find application in gas and liquid filtration in the automotive and chemical industries. Celanex PBT permits production of nonwovens with very high basis weights, they are good option polymers for the manufacture of nonwovens for thermal and acoustic insulation. Celanex PBT 2008 has been successfully used in meltblown nonwovens with very fine structures for blood filtration and fuel filtration Other applications include binder fibers made from Celanex PBT for thermal bonding of PET spunbonded nonwovens.
