Fabric Comparison Chart Bookmark and Share

Posted by Sazid Rahman

Identifying fabric is important. More important is the comparison of fabrics. This makes us know the true quality of a fabric by differentiating it from its substitutes. The following chart gives a complete information upon different types of fabric at a glance. It gives information about the weaves of the fabric, its characteristics and the uses, the important part of comparison.

Another table is given at the bottom, which shows the comparison of only the characteristics of few fabrics. For example, water retention is very high in cotton and the lowest in polypropylene. Same with the drying time taken, very long in cotton and vice versa in polypropylene. Cotton and wool shrinks more than polyester and nylon.

Efficient Water Utilisation in Textile Wet Processing Bookmark and Share

Posted by Sazid Rahman

A paper published in the journal of The Institution of Engineers (India) by Prof S Balachandran and Dr R Rudramoorthy.

Abstract: The amount of water used in various textile wet processing mills vary depending on the equipment, process adopted and types of fabric. However, improper operation and lack of maintenance have resulted in excessive water usage in these units. A recent study on water audit in selected textile processing units at Tirupur cluster have confirmed this fact. Water is becoming scarce and also the quality of available water is deteriorating. Hence it is worthwhile to consider various steps in order to reduce the consumption and also the amount of effluents discharged from the plants. In this paper, a review of various water conservation techniques is being presented so that industry can benefit to a considerable extent by adopting these measures.
