  CURRENT TRENDS IN FASHION TECHNOLOGY & TEXTILE ENGINEERING - JUNIPER PUBLISHERS Authored by  Anowar Hossain, Abstract Different engineering setting of Draft Change Pinion like 13, 15, 17, 19, 21 were studied for production of cotton carded sliver and polyester carded sliver in a specific setting of carding machine to observe the card sliver variation, card sliver evenness, card sliver neps as well as sliver irregularity considering the geometrical variation of sliver surface. Weight fluctuation of 10 different samples were studied for different engineering setting of Draft Change Pinion (DCP) like 13, 15, 17, 19, 21 and samples of DCP 17 was observed more homogeneous than other samples studied in this experiment both for cotton and polyester carded sample under observation of weight variation of 10 different carded sample. The overall weight variation in cotton and polyester sliver/6yds is considered in general as DCP-13 Keywords:  Cotton carded sliver; Polyester ca...

  CURRENT TRENDS IN FASHION TECHNOLOGY & TEXTILE ENGINEERING -  JUNIPER PUBLISHERS Abstract In this work, we have developed an efficient and simple protocol for the synthesis of novel A-π-D-π-A NIR azo dyes. The near infrared absorbing azo dyes were synthesized by using 2-hydroxy-1, 4 naphthoquinone (Lawsone) and different substituted aromatic primary amines. Furthermore, author developed push-pull chromophores of A-π-D-π-A type containing an electron-withdrawing azo core, phenazine moieties, and a hydroxyl group as electron donor. The benzo [a] quinoxalino [2,3-i] phenazin-5-ol moiety was introduced to make the system planer as well as to increase the π-conjugation. The optical properties of these dyes were studied in N, N-dimethylformamide (DMF). Keywords:  NIR Absorbing azo dyes; 2-hydroxy-1; 4 Naphthoquinone; Lawsone; Optical properties; Phenazine core Introduction In 1856, William Henry Perkin accidentally discovered the world’s first commercially successful synt...

Journal of Fashion Technology -  Juniper publishers Abstract Textile industries are focusing on minimizing their production costs by using sustainable technologies and by inventing new methods. Pretreatment is the heart of textile wet processing. Most of the Textile Companies are using combined pretreatment process with exhaust and semi-continuous method. After the treatment is over, the bath with residual chemicals are drained out into effluent treatment plant. In this study, an attempt has been made to reuse the residual chemicals by replenishing the measured amounts of chemicals again for combined pretreatment process. The concentration of the main chemicals, after pretreatment, before draining was analyzed and quantified. In case of pretreatment process in a Jigger machine, the liquor is drained out after three turns (6 ends) with residual chemicals, then the concentrations of H2O2 and NaOH was assessed in that. In case of pad-roll bleaching, the fabric roll is ...
