  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).

  CURRENT TRENDS IN FASHION TECHNOLOGY & TEXTILE ENGINEERING - JUNIPER PUBLISHERS Fashion and textile products evolve through several processes that involve the conversion of fibre to yarn, yarn to fabric and fabric to garment. During these processes, there are numerous evidences from the past that the fashion and textile producers are not giving much attention to sustainable practices. With the growing global interest on sustainability and increased consumer awareness, fashion and textile industries have taken initiatives to offer sustainable solutions in their production lines. There are a number of approaches taken by the stakeholders in the fashion production starting from fibre production to garment manufacturing even the supply chain management to fulfil the sustainability requirements. Fashion items produced using sustainable practises can contribute to environmental, social, and economic well-being leading to a green earth in the future. This review presents the data and fi
