A wet processing technology which uses air in form of dispersion foam for the media of application is called foam finishing. The process consists of mechanically forming a suitable formulated finish or dye formulation and then applying the foam to textile fabrics. Collapse of the foam distributes the finish on the substrate. The fabric is[…]
Optical Brightening Agents (OBA) are colorless or very pale yellow colored organic compounds which when added to a substrate increase the apparent reflectance in the visible by converting ultra-violet radiation into visible light and thus increase the whiteness or brightness. An OBA can be called a colorless dye which has some substractivity for the fibre[…]
Water resistant and Wind resistant clothing It is seen that the human body can lose temperature in various method. Especially in freezing weather and air-blowing situation, the temperature of the human body can be lost very quickly. In cold weather, a person riding a bicycle can lose temperature very quickly. Under these circumstances, the person[…]
Heat Setting Heat-setting can be defined as a treatment by which shape retention, crease resistance, elasticity etc. is given to the fibres. It also changes the strength, softness and dye-ability of the material. All these changes are directly connected with the structural and chemical modifications occurring in the fibre. The heat-setting process is mainly used[…]
Stenter machine is not only a dryer but also used for many other purposes. Here knitted and woven fabric in open width form is treated. This multipurpose machine is used for the following purposes: Drying Heat setting Width control Curing Finishing chemical application Selvedge printing Uniform moisture control for pad batch dyeing Loop control Weft[…]
Definition of Resin Synthetic resins are complex organic products of high molecular weight. Resin results when a number of simple molecular of low molecular weight become jointed together and to end to form much longer molecules which may be linear or linear molecules cross-linked. The main outlet of resins has been the plastic industry and[…]
