Textile Materials in the Processing of Lamination and Coating with Uses

Abstract

Cellulose acetate as a component of coatings was the first plastic to be manufactured for bond collars in shirt manufacturing in the year 1930 and in the process solvent was applied to soften the cellulose acetate. Coating and lamination are the two common processes for textiles to make impermeable. Bonding is the most important factor in coated materials and in which layers are bonded closely together either by the action of adhesive or by the properties of the adhesive applied. For the improvement in structural performance modification of the surface is a novel approach either by coating or lamination. There are several techniques available for the coating and lamination of textiles. Due to the sturdiness and availability of cotton, it is the most common and popular fabric used in lamination. PUR adhesive is heated in the hot-melt gravure process of lamination and the adhesive is heated till it reaches the required level of viscosity is obtained. For the purpose of making laminating emery paper, PUR hot-melt is used due to its very high initial strength and optimum adhesion of reignited the particular paper. Laminated fabrics to be used for agricultural purposes must be waterproofed weather resistant and sturdy. Laminated fabrics behave as separate fabrics under bonded structures and provide greater tensile strength. Laminated fabrics are also used for aerospace purposes. Among the various applications of coated and laminated fabrics, two important uses are in smoke and fire curtains.
