Description :
Cotton is the worlds most used fiber. Cotton is a natural fiber and is used in a wide variety of clothing and home furnishings. It is a natural fiber that is obtained from cotton linters. The cotton is a relatively pure and inexpensive source of cellulose. Cotton has a combination of desirable properties, making it suitable for many uses. It has properties of low cost, low resiliency, launderability, and absorbency. The low cost is perhaps one factor that led to the wide use of cotton for textiles. Cotton is easily washed and dry-cleaned. Cotton is a good strong fabric that is absorbent, and easy to work with. Cottons strength increases by approximately 25 percent when wet, which is important in washing and ironing. The strength of cotton is improved by treating it with caustic soda, the process called mercerization also increases its luster and affinity for dyes. This paper studied wash fastness properties on direct dyed cotton fabric. This work aimed to study the wash fastness of the dyes by washing them with popular detergents. The dyed cotton fabrics color strength and wash fastness were evaluated and compared using the Greyscale method. The studies revealed that the dyeing property of the fabrics after washing with water and different detergents was very much affected. It can be concluded that the direct dyed fabrics have bad dyeing and wash-fastness properties.
