Effect of Acids and Metal Salt Pretreatments on Acrylic Dyeability

Effect of Acids and Metal Salt Pretreatments on Acrylic Dyeability Acrylic fabrics are treated with aluminum sulphate, copper sulphate, tannic acid and isophthalic-5-sodiumsulphonic acid in different concentrations and various temperatures in presence and absence of plasticizer agents, such as dimethylformamide (DMF) or dimethylsulphoxide (DMSO). The treatment is carried out by two techniques (padding and exhaustion). Then, pretreated acrylic fabrics are dyed with cationic and acid dyes for various times. The effects of the treatments on the mechanical and physical properties of the treated acrylic fabrics such as moisture regain, roughness, tensile strength, elongation and bending stiffness are thoroughly investigated. Infrared spectroscopic analysis has been used to suggest changes in the treated acrylic fabrics. The dyeability of the treated fabrics by both cationic and acid dyestuffs is studied. The effects of the treatments with metal salts and acids on fastness properties of dyed acrylic fabrics are estimated. The pretreatment improves the dyeability of acrylic fabrics modified with both cationic and acid dyestuffs and also their fastness properties. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Research Journal of Textile and Apparel Emerald Publishing

Abstract

Acrylic fabrics are treated with aluminum sulphate, copper sulphate, tannic acid and isophthalic-5-sodiumsulphonic acid in different concentrations and various temperatures in presence and absence of plasticizer agents, such as dimethylformamide (DMF) or dimethylsulphoxide (DMSO). The treatment is carried out by two techniques (padding and exhaustion). Then, pretreated acrylic fabrics are dyed with cationic and acid dyes for various times. The effects of the treatments on the mechanical and physical properties of the treated acrylic fabrics such as moisture regain, roughness, tensile strength, elongation and bending stiffness are thoroughly investigated. Infrared spectroscopic analysis has been used to suggest changes in the treated acrylic fabrics. The dyeability of the treated fabrics by both cationic and acid dyestuffs is studied. The effects of the treatments with metal salts and acids on fastness properties of dyed acrylic fabrics are estimated. The pretreatment improves the dyeability of acrylic fabrics modified with both cationic and acid dyestuffs and also their fastness properties.
