Метка: Fibers

Today, more than half of the 80 million metric tons of fibers consumed per annum are synthetic. Synthetic fibers are largely used in technical textiles and fabrics to meet all kind of mechanical, aesthetic and durability requirements.

Synthetic fibers continue their rapid growth in a variety of end use applications such as nonwoven for consumer goods, construction materials, textiles for automotive as well as mono-filaments for artificial grass used in sport fields or landscaping.
Polypropylene is a very important material used in BCF (bulk continuous fiber) processing, nonwoven fibers spinning or the associated weaved tapes. Polyethylene and Polyamide mono-filaments as well as polyester are other important polymers for technical synthetic fibers.

Technical man-made fibers, initially developed and produced in Western countries to compensate for the declining textile clothing activities, are now expanding worldwide fueled by the demand of the rising middle-class population.

UV and Light stabilizers to protect synthetic fibers from degradation

Synthetic fibers are subject to thermo- and photooxidative degradation during polymer processing, spinning and later service life. Fibers used in applications such as artificial turf, barrier membranes or carpets and flooring have to withstand very harsh climate conditions, including prolonged exposure to UV light and environmental pollution or contaminants. Very demanding long-term durability is essential in some end applications, such as construction and automotive.

Irganox® antioxidants, Chimassorb® and Tinuvin® Light stabilizers protect the fiber from adverse thermal and UV aging such as discoloration and degradation.

Which solutions can BASF offer to answer the synthetic fibers industry requirements?

 

BASF solutions for fibers used in construction materials:

Fibers are used in architectural barrier membranes including geotextiles, roof felts used under roof tiles and house-wrap surroundings for insulation. Both can be laminated onto microporous films for breathability.

See BASF solutions suitable for fibers used in construction:

Applications	Fibers types	BASF solutions
Geotextiles Shading nets Roof felts Housewraps	Woven and nonwoven polyolefins Polyester Occasionally Polyvinylchloride (PVC)	For Polypropylene fibers: Chimassorb® 2020 Tinuvin® 234 Flamestab® NOR® 116 For Polyamide fibers: Chimassorb® 2020 Tinuvin® 234 Uvinul® 4050

Focusing on the safety aspect of construction materials, BASF supplies flame retardants that help meeting regulations for construction materials as well as light-stability for insulation membranes.

BASF light stabilizers for the nonwoven sector:

The nonwoven sector covers a very wide variety of applications including hygiene, air filtration, construction and geotextiles. Polypropylene is the polymer used in large majority of applications.

Here are BASF additives recommended for the nonwoven sector:

Applications & Requirements	BASF solutions	Products Benefits
Construction: Geotextiles, insulation or membranes, composites with films or other textiles	Chimassorb® 2020 Flamestab® NOR® 116	Processing stability Spinning stability Outstanding UV resistance Flame Retardancy
