Cotton is more easily affected by microorganisms, because of the large surface area and ability to retain moisture on the fabric. These effects include the generation of unpleasant odour, stains, discolouration in the fabric, a reduction in the tensile strength of the fabric and an increased likelihood of contamination. Cotton fibres does not have any special properties like antimicrobial resistance in naturally. So special finishing like antimicrobial, flame retardant, UV protection, and other finishing were given to the cotton textile at the final finishing process, but the fastness properties of such finishing is not durable. So in order to the make the cotton textiles processing an permanent antimicrobial finishing using speciality fibres, which will be blended with cotton fibres at the blow room stage of spinning. A minimum proportion of speciality will be used to achieve an antimicrobial properties in the blended yarns and fabrics to produces durable finishing and non-leaching products. Such new products produced through intimate blending of fibres can be applied to production of apparel and home textiles such as active wear, hosiery, under wear, carpeting and upholstery for controlling odour and staining for antimicrobial property.
