Abstract: Stitch length and GSM (gram per square meter) are the two major parameters for making a knit fabric. The relationship between stitch length (S.L) and GSM is inversely proportional if the other parameter remain constant. Again the presence of tuck loop in knit fabric structure make the fabric heavier than the plain single jersey fabric having all knit loop because of the accumulation of yarn in the tucking place. In this study, an experimental work was offered to understand the influence of different stitch length on the GSM of knit fabric with respect to the change of tuck loop percentage in the knit fabric structure. Here three fabric (single jersey, single lacoste and polo pique) having different tuck loops percentage with five different stitch lengths were selected where the other parameters were constant.

Abstract: In this study we prepared high density polyethylene (HDPE)/ clay nanocomposites by melt compounding in a twin screw extruder with rotational speed of 50rpm and the temperatures of the zones are set to 180-210°C.Different screw configuration have been used to study the effect of screw elements on the properties of nanocomposites. screw configuration changed from dispersive to distributive type. Cloisite 15A was used as the filler and weight percent of clay was fixed to 3wt%. Maleated polyethylene grafted polyolefins supplied from Reliance ltd. A new combination of maleic anhydride grafted polyethylene prepared in our lab through grafting also taken as compatibilizer.

Abstract: Dyeing of fabric blends such as Polyester/Cotton (P/C) is presently done with two chemically different classes of dyes namely disperse for polyester and reactive for cotton, in two bath process. Experimental work was carried out on finding the possibility of dyeing the P/C blends in one bath process without drain the liquor after polyester part dyeing. All the existing chemical and conventional temperature range were applied in this study. The result indicates that, the using of one bath method in the polyester cotton dyeing can slightly change the fastness properties than the conventional method. The one bath dyeing method showed level dyeing having good fastness properties and offers the option of cost effective and eco-friendly dyeing process.

Abstract: Printing is a renowned process in textile industry which is generally done after dyeing. It is the last process to enhance aesthetic appeal of the fabric. Most of the buyer provide order of garments including printing process as various design can be imparted on the face side of garments indicating particular style and taste of the customer. Piece print has been able to draw the attention of customer by its variation of design. There are so many methods have been invented to apply the print paste onto the piece of garments.But the article related to piece print is not as much as available like all over print. This article deals with difference between all over print and piece print and various piece printing process on textile materials that frequently used.
