Study of cellulase adsorption on indigo particles and insoluble cellulose, as well as experiments on indigo interaction with immobilized amino acids together with theoretical analysis of three-dimensional structures of enzyme molecules, provided an evidence that certain cellulases, which have hydrophobic domains (clusters of closely located aromatic and non-polar residues) on their surface, may...

Denim jeans, dyed with natural or synthetic indigo, are the most popular garments worn by individuals of all ages and approximately one billion pairs of jeans are produced per annum. Traditionally, denim has been woven with cotton in a warp face twill weave, in which the warp is blue whereas the weft is white. Dyeing is usually performed with pure indigo, or indigo combined with a sulfur dye to...

The process, which is defined as ultrasonic treatment or cavitation, ensures that the dirt removed from surfaces without damaging fabric surface. There are studies on washing processes of denim fabrics in literature, but there no study effect cavitation process thermal comfort fabrics. For this purpose, were treated at three different times, 15, 30, and 45 minutes, two frequencies 8khz 16khz ho...

Sandblasting denim using silica has emerged as a new cause of silicosis in Turkey. Following the discovery of several cases of silicosis in (young) workers who used this process, the frequency and main occupational risk factors of silicosis among former denim sandblasters in the region of Erzurum (Turkey) were evaluated. Demographic characteristics and information on working conditions were obt...

Three 100% cotton denim jeans were treated with stone acid wash with the variation of processing time (1.5, 2 & 2.5 minutes) and concentration (1.5, 2 & 2.5g/l) of potassium permanganate after typical enzyme bleach wash. Various physical and mechanical properties (Hand feel, Weight, EPI, and PPI, Tensile strength, Shrinkage, Seam strength, Count & stiffness) were investigated before and after e...

The denim is a fabric woven from coarse indigo dyed warp and grey un-dyed weft yarn. Denim fabric is hard-wearing and has high density with a high mass per unit area and a 3/1 or 2/1-twill weaves construction. It is comfortable, fashionable, affordable, durable and a popular clothing material. Nowadays, the stretchable denims are in fashion due to its comfort fit and flexibility. These fabrics ...
