Abstract/ Executive Summary:

The effects of combined scouring-bleaching and reactive dyeing were investigated by characterizing the functional groups changed of cotton, betel nut, banana and jute fibers using caustic soda, Hydrogen peroxide and reactive dyestuffs. FTIR ATR spectroscopy provided a fast and semi-quantitative assessment of the removal of pectin, lignin, Hemicelluloses, oil, waxes etc on those fibers surface by comparing the changes in intensity of the carbonyl peak induced by Hydrogen peroxide and caustic soda treatments well as bond changing in reactive dyeing around 4000 cm-1. Above all fibers are not reacting identically during changing impurities and covalent bond forming between cellulose and reactive dyes.

Objectives:

The present paper focuses chemical behavior of different sources cellulose, such as cotton, jute, banana and Betel nut fibers, by presenting a comparative analysis with the combined scouring & bleaching and reactive dyeing, using Fourier transform infrared spectroscopy (FTIR).

Methodology:

CIS Cotton fibers were obtained from Silver line Spinning Ltd and Bangladeshi betel Nut, banana & white-B jute were extracted and collected from different sources. Combined scouring-bleaching carried out for all fibers by treating @ of Fino wet OSR (Detergent): 1 gm/l, Caustic soda: 5 gm/l (Dosing at 60⁰C for 10 min), Hydrogen Peroxide: 3 gm/l, Albafluid C (Anti-creasing agent): 1 gm/l, Arboquest 340 (Sequestering agent): 0.5 gm/l, Time: 40 min, Temperature: 900C. Neutralization (Acetic acid: 1 gm/l Time: 10 min Temperature: 60⁰C). Reactive dyeing is carried out @ of GSS (Leveling agent): 0.12 gm/l, Arboquest 340 (Sequester): 1 gm/l, Albafluid C (Anti-creasing): 1 gm/l,Glauber salt: 35 gm/l, Reactive Turquoise Blue H2GP: 3%, Sodium carbonate: 15 gm/l (at 50⁰C for 20 min.),Time: 30 min, Temperature: 60⁰C. Cold wash (Acetic acid: 1.5 gm/L, Time: 15 min, Temperature: 40⁰C). Hot wash (Jintex /Detergent: 1 gm/l, Time: 20 min. Temperature: 90⁰C). Cold wash (Time: 10 min. Temperature: 40⁰C).

Three samples pallet were prepared for each of four fibers (raw fiber sample pallet, combined scouring bleaching sample pallet and reactive dyed sample pallet). Thermo Nicolet Nexus FTIR spectrophotometer equipped with liquid nitrogen cooled MCT-A detector was used. Transmission mode spectra (32 scans, 4 cm-1 resolution) were measured with KBr pellets of powdered fibers. FT-IR ATR spectra (216 scans, 4 cm-1 resolution) were collected with a MIRacle, single reflection horizontal ATR accessory (PIKE instruments) having a diamond ATR crystal fixed at incident angle of 450. A 10 mm×10 mm piece of each fiber pallet were mounted on top of ATR crystal and pressed gently by a pre-mounted sample clamp. ATR effect and atmospheric contributions from carbon dioxide and water vapor were corrected by the Omnic software.

Achievement/Findings:

FTIR ATR spectroscopy test has been reported that cotton, jute, banana and betel nut fibers contain different amount of cellulose and various impurities which are not identically sensitive under hot caustic and hydrogen peroxide treatment as well as covalent bonding in reactive dyeing. It is proved that 100% wax cannot be removed from cotton through caustic treatment and residual lignin must be present in banana, jute and betel nut after combined scouring- bleaching. It is also graphically represented that cotton formed covalent bond strongly but less strong in jute, banana and betel nut consecutively after reactive dyeing. It is suggested that reactive dye is not fairly suitable for betel nut, if it is required deep shade. It is strongly recommended that lignin from banana, jute and betel nut can be removed, if their cellulose totally disintegrated into micro fibril.
