* Ultraviolet Absorber
ABSTRACT: Cotton fabrics have been dyed withthe following dyes,Reactive Yellow 84, Reactive Red 22 and Reactive Blue198 dyesand the effect of combined application of commonly used antioxidant such as gallic acid, vitamin C and cafeic acid, and the ultraviolet absorbers
such as 2-hydroxybenzophenone and phenyl salicylateis studied in order to improve light fastness property.Application of antioxidant and ultraviolet absorber
on dyed fabric is carried by exhaust and pad dry cure methods.Light fastness and rubbing fastness properties of the treated samples were tested as per international standards.The durability of chemical treatments to ten washing cyclewas also investigated and found that the pad dry cure method of application shows good result.
The suitable antiaging agents for PU materials mainly include ultraviolet absorber
, antioxidant , hindered amine [7, 8], and others [9,10].
Sanduvor VSU white, free-flowing oxalanilide-type, nonhydroxy substituted ultraviolet absorber
with reportedly excellent thermal stability recommended for thermoplastic polyester fibers, PVC, unsaturated polyesters, styrenic PC, polyacetal, polyamides, polymethyl methacrylate, PUR, and coatings resins.
The ultraviolet absorber
includes ethyl-2-cyano-3,3-diphenyl acrylate; octyl-2-cyano-3,3-diphenyl acrylate; 2'-ethylhexyl-2-cyano-3,3-diphenyl acrylate; phenyl salicylate; p-t-butylphenyl salicylate, and 2, 4-dit-butylphenyl-3',5'-di-t-butyl-4'-hydroxybenzoate.
Provides Sanduvor VSU white, free-flowing oxalanilide-type ultraviolet absorber
with excellent thermal stability.
The resulting six-layer wall includes an oxygen barrier and an ultraviolet absorber
This new class of ultraviolet absorber
derives from an organic, water-soluble material, which has a strong affinity for the textile materials.
The light stabilisers include ultraviolet absorbers
that help to shield the plastic polymers from sunlight.
THE STATUS of the 24 over-the-counter (OTC) ultraviolet absorbers
approved for use since 1978 is on life-support.
SONGWON is expanding its range of ultraviolet absorbers
(UVAs) for high performance coatings by launching two new products: SONGSORB CS 400and SONGSORB CS 384-2.
