Question 50 (Textile Technology & Fibre Science)

If the moisture regain (%) and moisture content (%) of a fibre are the same then the value of moisture regain (%) is __0__.

[Show Answer]

write here


Moisture regain(M)=(W/D)*100

Moisture content(C)=(W/(W+D))*100

Where, W=weight of water and D=oven dry weight of material

As given in the question
Moisture regain(M) =Moisture content(C)
(W/D)*100 =(W/(W+D))*100
1/D=1/(W+D) ,
Now, Moisture regain(R)=(W/D)*100

Moisture regain(R) =0 (Answer)
