DYEING PROPERTIES OF ACRYLIC FIBRES

Improved Fastness Properties of some Novel Triarylmethane Dyes on Acrylic Fibres

In this research, several series of triarylmethane dyes containing one or more terminal methoxy substituents with a variable tertiary amino groups have been used. These dyes have been applied to different substrates by using various methods including transfer printing and then their fastness properties were measured. These dyes shows exceptionally high light fastness (6-7) on acid modified poly...

Investigation into the Dyeing of Soybean Fibres with Natural Dyes and their antimicrobial properties

The dyeing behaviour of annually renewable soybean protein fibres with Madder, Weld and Walnut seed husk, natural dyes, were investigated and their possible antimicrobial effects were evaluated. The results obtained from the dyeing of the Madder on the soybean fabric were compared with those on a wool fabric. It was shown that the amount of the amino acid content of the fibre has a great effect...

Pretreatment of Proteinic and Synthetic Fibres Prior to Dyeing

Improved Fastness Properties of some Novel Triarylmethane Dyes on Acrylic Fibres

Using a nitrilase for the surface modification of acrylic fibres.

The surface of an acrylic fibre was modified with a commercial nitrilase (EC 3.5.5.1). The effect of fibre solvents and polyols on nitrilase catalysis efficiency and stability was investigated. The nitrilase action on the acrylic fabric was improved by the combined addition of 1 M sorbitol and 4% N, N-dimethylacetamide. The colour levels for samples treated with nitrilase increased 156% compari...
