you are given two fibers, nylon and wool. how will you determined the water absorbers capacity of the given fibers. and also mention which fibre has more water absorbing capacity
Answers
Answer:
Explanation:
The absorbency of the fabrics is determined by the time the sample takes to absorb a fixed amount (usually a drop) of distilled or deionized water. Sample conditioning is extremely important as the residual moisture on the sample to be measured can affect the absorbency results considerably. The sample under a set tension (mounted on an embroidery hoop) is placed vertically at the prescribed distance from the end of a burette with water. The time starting from the moment the water drop touches the surface of the sample to the moment the water drop is completely absorbed by the sample (disappearance of the liquid reflection) is taken on a stopwatch. One sample should be measured at least five times to get an averaged result. The longer the time, the lower the absorbency. A more critical examination of fabric absorbency can be achieved using a 50% or 65% sucrose solution, because the sucrose solution is more viscous and is absorbed more slowly than water, thus distinguishing between samples with very small differences in their water absorbency.
