Desizing, irrespective of what the desizing agent is, involves impregnation of the fabric with the desizing agent, allowing the desizing agent to degrade or solubilise the size material, and finally to wash out the degradation products. The major desizing processes are: Enzymatic desizing of starches on cotton fabrics; Oxidative desizing; Acid ...
The other three streams in textile engineering are yarn engineering, fabric engineering, and apparel engineering. The processes of this stream are involved or carried out in an aqueous stage. Hence, it is called a wet process which usually covers pre-treatment, dyeing, printing, and finishing. [2]
Scouring agents are the cleaning agents that remove the impurities from the textiles during the scouring process. While these are now industrially-produced, scouring agents were once produced locally; lant or stale urine and lixivium , a solution of alkaline salts extracted from wood ashes , were among the earliest scouring agents.
Textile manufacturing in the modern era is an evolved form of the art and craft industries. Until the 18th and 19th centuries, the textile industry was a household work. It became mechanised in the 18th and 19th centuries, and has continued to develop through science and technology since the twentieth century. [2]
Cold pad batch (CPB) is a method of dyeing textiles, typically cellulosic fibers such as cotton, in which the textile is impregnated with dye in a cold state, rather than being heated. High dye fixation and no thermal energy are the advantages of the CPB process. [1]
Textile finishing machinery, Red Bridge Mills, Ainsworth, 1983. In textile manufacturing, finishing refers to the processes that convert the woven or knitted cloth into a usable material and more specifically to any process performed after dyeing the yarn or fabric to improve the look, performance, or "hand" (feel) of the finish textile or ...
Many recipes for size can be found in textile manufacturing books. The recipes include flour, sago, china clay, types of soap, fats and some chemicals. [2] [3] Before mechanisation, the sizing process was a time-consuming task. The weaver painted the size onto the warp as it lay on the loom, then fanned it dry before weaving the cloth. The ...
Singeing is a surface finishing procedure that is followed by mercerising, dyeing, printing, and other textile manufacturing steps. When Greige goods leave the loom, they may have a downy appearance with protruding fibers, which is undesirable for printed goods. The application takes place on loom goods or the yarn stage itself.
