How will you evaluate maturity of cotton fibre sample using caustic soda swelling methods?

 Evaluate Cotton Fiber Maturity How will you evaluate the maturity of cotton fiber sample using caustic soda swelling methods? questionsoftextileblog know textile The caustic soda swelling method is a laboratory test used to determine the maturity of cotton fiber samples. The test measures the ability of the fiber to absorb and retain a solution of caustic soda, which is an alkaline substance. The results of the test are used to determine the degree of maturity and quality of the fiber, as well as to identify potential processing issues that may affect the performance of the fiber during spinning and weaving. To perform the caustic soda swelling method, the following steps are followed: Preparation of the sample : The cotton fiber sample is cleaned and prepared for testing by removing any impurities and ensuring that it is free of contaminants. Weighing of the sample : A sample of cotton fiber is weighed to determine the weight of the fiber that will be used for the test. Preparati...

Proved that mean pore diameter of nonwoven fabric dp is independent of fibre diameter d and dependent on fibre length l.

Assume all fibers were randomly deposited in an elementary plane then prove that the mean pore diameter of the nonwoven fabric  d p  is independent of fiber diameter and dependent on fiber length l. Fig: randomly oriented fibres questionsoftextileblog Know textile Let the fibers be distributed randomly in an elementary plan of unit area and the probability of n fibers that present per unit area is given by Poisson distribution P(n) = e -c * c n / n!    ,  where c is total projected area fibres per unit area of the plane (total coverage). Evendently, c=nld,  where  l= fibre lingth and d=fibre width (diameter) The fraction of area covered by one fibre is: P(0) = e -c = ξ        -----------(i) Clearly, (1-ξ ) is the fraction of the unit area covered by fibres. The total area A c  occupied by all fibres croosing per unit area of the plane is: A c = ∑ n=2 n→∝ (n-1)P(n) = ∑ n=2 n→∝ (n-1) e -c * c n / n! = e -c [ c 2 / 2! ...
