Modification is defined as a limited change in any material. Surface modification provides some physical and/ or chemical changes on the surface of the materials without effecting their bulk properties. With these modification methods which are classified as chemical, physicochemical and biochemical some properties can be enchanged or given single or multi-functions to the textile materials for various applications. Chemical modification of textiles is carried out with application and reaction of any kind of chemical agent to the material. If the textile material is exposured to the chemicals long time, color, mechanic and chemical properties of the material can be changed. Because of disadvantages of chemical modifications, researhers tend to improve and accessibility of physicochemical modifications. Corona discharge, heat treatments, plasmas, UV and g- radiations electron or ion bombardement, ozon can be given as an example for physicochemical. Another alternative method is biochemical modification with enzymes. Enzymes are used in desizing (amylase) for the first time in textile industry and now they can be used in many applications from pretreatment to finishing of both synthetic and natural fibres.
Key Words: Surface modification, chemical modification, physicochemical modification, biochemical modification, corona discharge.
