Bagasse is a load of waste of caster sugar industry about 20 millions tons per year over 80 percents are used to be fuel and raw materials for the other industries. Anyhow much more bagasse is abundant. Then attention in textile industry application. Because of biodegradable and environment friendly. This research was studied about fiber separation and shockproof production from the bagasse. Fiber separation by chemical process. There are variable in amount of sodium hydroxide boiling time and produced to web by field latex 100 percents at 100 degree celsius. Physical properties of web such as thickness weight per unit area bursting and tearing strength was estimated. The appropriate condition for fiber separation as follows : sodium hydroxide 180 g/l for 2 hours. Average thickness is 2.83-2.90 millimeter. Average weight per unit area is 0.57 g/in2. Average bursting and tearing strength are 371.1 N and 756 mN respectively. The web is suitable for shockproof production

In the current practice cotton fabric is predominantly dyed with direct dyes in the presence of a considerable amount of electrolyte (Salt) to reduce negative charge on fiber surface. Thus the high concentration (40-100 g/l) of electrolyte required in cotton fabric dyeing may pose additional effluent problem and waste water treatment costs. The use of polycationic agent to modify the dyeing behaviour of direct dyes on cotton fabric is investigated. Normally polycationic agent had been treated on dyed fabric to improve fastness properties. The comparison of untreated and pretreated cotton fabric was found that the polycationic agent offers the potential for different dyeing patterning possibilities. The dyes was fixed on the fiber by ionic force. So color strength and exhaustion of pretreated fabric was better than untreated fabric and increased in fastness properties even when dyeing had been carried out in the absence of electrolyte. The purpose of the present work was to determine whether the pretreatment of cotton fabric with polycationic agent could enhance the dyeability of the fiber with direct dyes under appropriate condition such as assuming a positive charge on fiber which permitted “electrolyte-free” dyeing after modification without drain and helped reduce dyeing cost.
