Title: Inverse relaxation in polyester-viscose MJS yarns Authors: Tyagi, G K; Salhotra, K R Abstract: The relationship between the magnitudes of the instrumental measurement of the inverse relaxation and some yarn factors has been investigated. It is observed that the inverse relaxation index and load induced are influenced by the blend composition, yarn linear density and first jet pressure. In MJS yarns, a systematic decrease in yarn linear density greatly increases the inverse relaxation index. The use of higher first jet pressure produces higher inverse relaxation but reduces load induced. Also, the inverse relaxation index increases with the increasing retraction level but shows descending relationship with the increasing polyester content. Page(s): 158-160

Title: Dyeing of ecru denim with onion extract using natural mordant combinations Authors: Deo, H T; Paul, Roshan Abstract: Ecru denim swatches were dyed with onion extract using natural mordants such as harda, tartaric acid and tannic acid separately and in combinations. Harda-tartaric acid combination was found to be the best followed by tannic acid-harda and tartaric acid- tannic acid combinations. Synergistic effect of mordant was observed while using the binary combinations of mordants. Meta-mordanting gave the best results for harda-tartaric acid and tartaric acid-tannic acid combinations, while pre-mordanting gave the best results for tartaric acid-harda combination. There was an overall improvement in performance properties of the samples dyed with various combinations over that of the single mordanted and the control samples. This new technique has immense potential in the modem concept of natural denim wear dyed with natural dyes using natural mordants. Page(s): 152-157

Title: Sublimation transfer printing of linen and polyester/linen fabrics Authors: El-Kashouti, M A; El-Halwagy, A A; El-Molla, M M Abstract: An attempt has been made to chemically modify the linen and polyester/linen fabrics via benzylation. Linen fabric is more susceptible to the benzylation reaction than its blend with polyester. The maximum degree of substitution obtained in the case of blend is 0.26 as compared to 0.85 in case of 100% linen when benzylation is conducted for 4h. Partial benzylation of linen and polyester/linen fabrics increases their transfer printability. Partially benzylated printed fabrics have high colour strength and their overall fastness properties are good to very good. Page(s): 147-151

Title: Effluent treatment in textile processing: Part II—Bleaching of cotton yarn Authors: Deo, H T; Chinta, S K Abstract: A new method of bleaching cotton yarn, which doubles the production with overall saving of 58% without sacrificing the bleached yarn quality, has been described. As no chlorine-based bleaching agent or chemical is used, the new method is environment-friendly. This method virtually obviates the need of costly effluent treatment plant and is particularly useful for the cottage industry in yarn dyeing sector. Page(s): 143-146
