A thorough examination on the influences of various mechanical properties of yarns and structural parameters of fabrics on the Poisson's ratios of a woven fabric is given.
The amount of water passing through the fabric is given by the change in weight of the blotting paper, which is used as an indication of water repellence of fabric.
If the filament displacement, normalized by the centre-to-centre separation between filaments, is ε, the enhancement in the flow rate through the enlarged opening in the fabric is given by approximately 2ε.
The flow of water vapour passing through the fabric is given by (Fourt et al., 1951): Q = frac{1}{R}times Dleft varDelta cright At where, Q is the amount of water vapour in g, R (a function of pores/openness) is the resistance offered by the fabric, D is the diffusion coefficient, ∆C is difference in vapour concentration, A is area in cm2 and t is time in s.
To impart this feature, the fabrics are given a treatment of mosquito repellent agent which capable of being utilized and without ruining their characteristics.
The results in terms of dE, K/S, relative strength, L, a, b, C, h values of all the dyed fabrics are given in the Table 2.
As a child she was given fabric scraps as playthings and soon began sewing and designing.
As part of this plan, serious consideration was given to protecting sensitive fabrics and restoring the interior of the ship.
Enzyme treatment was given yarn to both yarns and fabrics.
Then, this fabric was compared immediately with violet scale (Tegewa Scale) and accordingly rating was given.
