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.
