Color and Appeal

Ciba® TINOPAL® OB-ONE provides improved initial color and brilliant white polyamide fibers. It is effective at very low concentrations. The effectiveness will depend upon the processing conditions and possible interactions with other components in the formulation.

Comfort and Freshness

Public concern about freshness has been driving consumer demand for antimicrobials in polyamide fibers in apparel. Wear comfort and freshness are greatly increased by the use of Ciba® IRGAGUARD® antibacterial to reduce unpleasant body odor. Ciba® IRGAGUARD® B 1000 is a highly active organic antimicrobial effective against a wide range of Gram positive and Gram negative bacteria by inhibiting their growth. Ciba® IRGAGUARD® B 7000 is an inorganic silver based antimicrobial inhibiting the growth of bacteria, mold and yeast. The bioavailability of silver-ions is critical to the antimicrobial efficacy. The specific porous support determines the bioavailability of the silver-ions. The antimicrobial additives are thermally stable and can be incorporated during polyamide melt spinning.

Processing Efficiency

For processing stabilization of polyamide apparel fibers the use of the phenolic antioxidant Ciba® IRGANOX® 1098 improves the resistance to discolorations after oven aging and exhibits excellent retention of physical properties. It reduces fiber breakage which can occur due to higher spinning speeds. It can be added in polycondensation as well. Ciba® IRGANOX® B 1171 provides excellent initial color and enhanced color stability after oven aging.
