Title: Application of Guar (Cyamopsis tetragonoloba) Gum in Textile Industry- Printing, Dyeing and Sizin
Author: Algali, Elsiddig Mohamed Hussain
Abstract: The objective of this study is to investigate the use of Guar as a substitute to the Sodium Alginate in textile industry, as thickening agent for printing, dyeing and sizing. The research adopts the quantitative experimental methodology to measure and compare the physical properties of Solubility, Viscosity, pH and Washability of the two components. For solubility mixture of 2 grams of Guar Gum Powder in 100 mls of water showed no precipitation when filtered after 3 minutes while it took 5minutes with sodium alginate paste. The measured viscosity paste of 2 grams /100mls of water the viscosity was found to be 4000 centipoises for Sodium Alginate and 5200 centipoises for Guar Gum paste. For pH measured were measured for both Sodium Alginate and Guar Gum paste and found ranging between 6.94 – 7.04. For washability one drop of potassium iodine solution on the surface of finished fabric no colour change was observed.. Guar Gum was then applied as thickening agent for printing, dyeing and sizing in laboratory scale ,the results were compared with the result achieved after using Sodium Alginate Thickening agent were found typical . The final finished printed and dyed sample were tested for color brilliancy using measuring instrument (Spectrophotometer) giving 5 number for both samples indicating no difference were obtained between the two thickening agent. The same process were then applied in commercial scale in Nourtex Textile Mills and SUR using Guar Gum and Sodium Alginate as thickening agent for printing ,dyeing and sizing . Once again the results obtained for Guar Gum and Sodium Alginate were similar. These findings render the use of the environmentally friend Guar Gum as an excellent substitute for the imported Sodium Alginate, which will lead to minimize production cost in the textile industry in Sudan.
