    Effect of core material draft ratio and denier on core spun yarn and denim fabric properties pre and post washing
    (Elsevier Ltd, 2024-01-17) Hossain, M.A.; Hossain, M.A.,; Emon, J.H.; Islam, M.T.
    Core-spun yarn (CSY) is utilized for better fabric characteristics like stretchability, durability, and comfortability. The study aims to investigate the influence of spandex drafts of core-spun yarn on denim fabric characteristics before and after washing treatment. Two types of denim fabrics were produced from two types of core-spun yarn, namely 16 + 40D, and 16 + 70D by applying 2.8, 3.0, 3.20 spandex drafts for 16 + 40D, and 3.40, 3.50, 3.60 spandex drafts for 16 + 70D. Prepared denim fabrics were desized, and acid-washed and the properties of denim fabric before and after washing were investigated as a function of spandex drafts and deniers. Accurate count, twist, and better elongation percentage were observed at 2.80 draft for 16 + 40D CSY and 3.4 draft for 16 + 70D CSY, but a higher imperfection index (IPI) value was obtained on those drafts. The strength of the denim fabric prepared with 16 + 40D CSY and 16 + 70D CSY were higher at 2.8 and 3.6 drafts, respectively. Higher shrinkage (%), ends per inch (EPI), and fabric weight of denim fabric was obtained after washing compared to before washing. The width of both fabrics decreased when the fabric was washed. Exploring various drafts of core material and their correlations with yarn and fabric properties provides valuable insights for textile manufacturers seeking to produce denim fabrics with optimum quality.

    Investigating the properties of cotton fabric coating with polyacrylic rubber and using this polyacrylic rubber coated fabric as an alternative to polyethylene bags
    (Institute of Physics, 2023-04-02) Kawser, M.N.; Rahim, A.; Emon, J.H.; Bhattacherjee, J.; Dutta, P.,; Khujaev, O.; Karimov, S.
    Cotton fabric coated with polyacrylic rubber can be used as a replacement for polyethylene bags to avoid plastic pollution. In this research, we have investigated the use of polyacrylic rubber with 100% cotton fabric as a finishing agent where 2% of ammonium chloride was used as a catalyst. A pad-dry-cure technique was applied for the preparation of cotton fabric samples varying 6%, 8%, 10%, 12%, and 14% polyacrylic rubber. Tensile strength, tear strength, and bursting strength produced a balanced improvement in properties. After appealing gyro wash on each sample, it is established that the strength of the fabric has decreased slightly. Assessment of these properties has had a good impact on the strength of the fabric making which is a viable substitute for polyethylene bags. © Published under licence by IOP Publishing Ltd.
