“…But the 50 % and 66.7 % SL of card sliver are lower. This may be due to introduction of hooks in the process of carding [3][4][5]. Tables 6 and 7 show the changes in 2.5 %, 50 % and 66.7% span lengths in card sliver with change in lap hank and card draft.…”

“…The fibre length measurements can also be used both for assessing fibre breakage in processing and for fibre orientation at various process stages as done by some of the previous researchers [3][4][5]. In this regard, defining the fibre length distribution using fibrogram is an efficient way to study the fibre orientation and fibre breakage in spinning preparatory.…”

The effect of drafts at different stages of spinning process on fibre length distribution of slivers has been studied by using Taguchi Method and ANOVA technique. The L8 mixed orthogonal array was used to work out eight different slivers. Two different lap hanks, four different card drafts and two different draft/doublings at breaker and finisher were selected for the study. The fibrograph length measurements in terms of 2.5 %, 50 % and 66.7 % span lengths and mean lengths (mean length and upper half mean length) were studied. The 50% span length (SL) and 66.7% SL give an indication of fibre hooks in the sliver. These span lengths in card sliver first decrease and then increase with drafting at breaker and finisher sliver due to removal of hooks.

“…However, it may not always determine the interaction effect like other designs of experimental techniques. Considering the simplicity of the method and lower number of experimental runs required to optimise the process, Taguchi method can be a useful technique for optimizing textile processes [8][9][10][11][12][13].…”

Taguchi Method is explained in brief and one of the textile processes, called spinning process, is optimised by using Taguchi method for manufacturing optimum packing density of different technologies yarns. The effect of process variables like: lap hank, card draft, draft/doublings and drafts at speed frame, ring frame, rotor and air-jet spinning machine on packing density parameters of respective technology yarn was analysed. The effect of noise variables was also accounted for. The trends of change in packing density with process variables are opposite to those of yarn diameter and helix angle of ring, rotor and air-jet yarns studied. The packing density is found to be the highest in air-jet yarn and the lowest in rotor yarn. Increase in draft in air-jet spinner and decrease in rotor spinner increase packing density of the respective yarns. The change in noise variables does affect the packing density parameters of yarns. Result analysis using Taguchi Method was according to the perception of some of the previous researcher on the subject. Hence, Taguchi method can be also used to optimise a textile process, where the product quality is highly variable and dependent on the combination of number of processes as well as on machine parameters.

Biopolishing of cotton fabrics enhances appearance and handle of the fabrics without compromising on essential properties. Process of biopolishing is influenced by concentration of cellulases, temperature, pH, and duration of treatment, besides the activity levels of enzymes, method of mechanical agitations and construction features of fabrics. Optimization of process parameters, including mechanical agitations and fabric construction features, has been carried out using Taguchi methods followed by analysis of variance and confirmation tests. All the design parameters, used in the study, have predominant influence on weight loss, fabric strength after biopolishing while thickness, bursting strength, abrasion losses, and flexural rigidity of the fabrics were significantly influenced by the concentration of cellulases together with duration of treatment.
