The degumming of Mulberry, Muga, Tasar and Ericream silk substrates was investigated and compared. Experiments were carried out according to the Box-Behnken response surface design. On the basis of weight loss, absorbency, bending length, breaking load, elongation at break and crease recovery, optimum conditions for degumming with soap-soda were determined.

The control of fabric quality in terms of the basic structure, like yarn type, yarn count, twist multiplier, ends per inch and picks per inch, cover factor etc. is very important, as these parameters finally determine the quality aspects of the fabric during its interaction with the chemicals used in the process. In this work an attempt was made to investigate the influence of structural parameters of the yarn and fabric, like the yarn count, yarn twist multiplier and the p.p.i. on the final performance of desized, 100% cotton fabric. Desizing is the first stage of all the preparatory processes, wherein the size of the materials applied to the warp yarn during weaving is removed. This process determines the performance of the subsequent processes, such as the uniformity of scouring, bleaching, dyeing etc. which is quite crucial in maintaining the quality of the finished fabric.

Kontrola jakości tkaniny, poprzez jej podstawowe cechy (tj. typ przędzy, masa liniowa i współczynnik skrętu przędzy, gęstość wątku i osnowy, współczynnik pokrycia, etc.) jest bardzo istotna, ponieważ powyższe parametry wpływają na jakość tkaniny podczas procesu odklejania. W pracy badano wpływ parametrów strukturalnych przędzy (masa liniowa, współczynnik skrętu przędzy, gęstość wątku) i tkaniny na efekt odklejenia tkaniny bawełnianej. Odklejanie jest pierwszym etapem procesu przygotowawczego, podczas odklejania usuwa się z tkaniny klejonkę naniesioną w procesie tkania. Proces ten wpływa na jednolitość procesu prania, bielenia, barwienia itd. i dość mocno decyduje o jakości wykończonej tkaniny.

Strength of the fabric is an important property that decides and influences all other performance properties of the fabric. But though we all understand the importance of the strength of the fabric in daily wear, a systematic approach is required to correlate various strength properties with that of the yarn and fabric construction parameters. We are all aware of the effect of the individual factors like twist, count and cover factor on the strength behaviour of the fabric. However it is necessary to study the effect of all these parameters in combination with each other to ultimately influence the strength of the fabric. Such a study is also useful for designing of the fabric, depending upon the end use and the customer requirement as it is gaining importance in the recent fierce competitive scenario. In this study we have evaluated the strength properties of the fabric with respect to tensile, tear and bursting strength and correlated the results with respect to the yarn count, Twist Multiplier and picks per inch of the fabric using regression equations.
