| Abstract: | The effects of sodium hydroxide and sodium carbonate on the properties of linen such as weight loss, reflectance, tensile strength and absorbency have been studied by varying the alkali concentration along with the variation in temperature and duration of reaction to optimize the scouring conditions prior to bleaching and dyeing/finishing. Experiments were specially designed for finding out correlation between variable factors and responses. The correlationship between weight loss and reflectance has also been studied. The study suggests the existence of fair correlations between temperature/duration of reaction/concentration and weight loss/reflectance, whereas tensile strength and absorbency remain poorly influenced. Use of sodium carbonate (10 g/l) alone for 30 min at near boil (95°C) along with surfactant (2 g/l) is recommended as it results in saving in chemical cost without any adverse effect on quality. |
