Write a short note on following: a. Embossed calendaring b. Fiction calendaring |
|
Answer» (a) Embossed calendaring: It produces three-dimensional design on fabric. Embossing calendar consists of heated hollow metallic roller engraved with the embossing design and solid paper roller, twice the size of engraved roller. Fabric is drawn between the two rollers and designs are embossed on the fabric surfaces. If Celluloses fabrics are used for embossing purpose then effect will be temporary finish, however, Celluloses pre treated with resin will provide Semi durable embossing effect. Permanent embossing can be achieved on the Synthetic fabrics. (b) Fiction calendaring: This type of calendaring gives highly polished surface like Glazed Chintz Cotton fabric. If a very high gloss is required, then fabric is pre-impregnated with a wax emulsion and calendaring is carried out. If the fabric is pre-treated with resin then this is a semi-durable type of finish. |
