    Quality Assessment of Digital Printed Cotton and Viscose Fabrics
    (University of Agricultural Science, Dharwad, 2015-08) Uppinal, Spoorti V.; Mahale, Geeta
    The present study on “Quality assessment of digital printed cotton and viscose fabrics” was carried out during 2012-2015 with the objectives to study the potentiality of CAD applications on design outputs, to assess the quality characteristics and image quality of digital printed cotton and viscose fabrics and finally estimate the cost of digital printing on both fabrics. Two self structured questionnaires were formulated where the first was administered to the thirty textile experts to select the twenty images from the hundred images of the four categories of designs viz., Embroidery, Painting, Tie-dye and Woven images. The second questionnaire was administered to thirty textile experts to assess the image quality of the digital print on both fabrics by visual analysis method. Twenty selected images were scanned and details of image files were recorded for further printing process. Five different solid pantone colours were selected to assess physical and colourfastness properties. The results were analyzed applying suitable statistical tests. Results revealed that printing process enhanced the cloth count of both fabric samples. Irrespective of fibre content, type of printed colours maximum shrinkage observed in weft direction than warp. However, warp way GSM was maximum than weft way. The removal of pretreatment paste during printing processes influenced the stiffness of the both samples. Control fabric samples had lower crease recovery angle than the print colours. The results of colourfastness property revealed that higher number of washes affects the colour strength of the printed samples. The maximum loss in colour strength was observed in wet rubbing, alkali media perspiration and damp sublimation. Almost all viscose printed samples gave excellent ratings to colourfastness properties. In subjective evaluation highest preference given to lotus motif of both Kantha and Phulkari embroideries, Mughal and Madhubani paintings, pleating and spot dyeing, block and small checks weave. The cost of digital printed cotton fabric per square was Rs 141.4/- and viscose Rs 131.54/-.
