Moisture regain and moisture content

Moisture Regain and Moisture Content are two important parameters of Textile materials.

1. Moisture regain and moisture content

2. The ability of fibre to take up the moisture is known as absorbency . The absorbency is expressed in the terms of moisture regain and moisture content . Both are represented in percentage. Moisture absorption depends on the chemical nature and physical arrangement of fibre . The Indian atmosphere is generally very humid . In this conditions , our moisture managed fabric with moisture absorbent properties will ensure that the person wearing garment made of such fabrics is very comfortable and feels very near to nature. Introduction:

3. Moisture Regain : Moisture regain is defined as the percentage of the water present in a textile material of oven dry weight of the material. Measurements are done under standard testing conditions (70± 2℉ and 65% ±2% relative humidity). Saturation regain is the moisture regain of a material at 95-100% relative humidity. Wt. of the water in the material Moisture regain = × 100 Oven dry wt. of the material

4. What is Oven dry Weight? The constant weight obtained by drying textile materials at a specific temperature of (105±3 )℃ . We can also say that it is the weight of piece after it is oven dry and all water has been removed. What is Standard Moisture Regain ? The moisture absorbed by a particular weight sample in the standard atmosphere after treating at (105±3)℃ is called Standard Moisute Regain . It is also called official regain.

5. Moisture Content: Moisture content is defined as the percentage of water present in a textile material of total weight of the material. Wt. of water present in a material Moisture content = × 100 Total weight of the material The percentage of moisture in a textile material brought into equilibrium with a standard atmosphere after partial drying, calculated as percentage of the moisture-free weight.
