Factors effecting cotton dyeing performance using water betel nuts

Abstract

This research aims to study a Factors effecting cotton dyeing performance using water betel nuts. The extracts were prepared in proportion betel nut : water 1: 5 ratio betel nut : red lime : Piper betel Linn is 4 : 3 : 1, 8 : 6 : 1 and 10 : 8 : 1 respectively. Selection ratio mixtures suitable for dyeing combined with fixing agent various types of three concentrations boiled for 40 minutes contain salt 10%, 20% and 30%, alum 0.3%, 1.6% and 3.3%, salt 3.3% and alum 0.3%, salt 1.6% and alum 0.3%, salt 0.3% and alum 0.3% after the reasonable period of time to dyeing cotton and fixing agent by selecting the type and concentration of fixing agent which a color the best. The time it takes to boiled 20, 40 and 60 minutes. The result of the study reveals that the proportion of betel nut, red lime and Piper betel Linn identified in cotton is 8 : 6 : 1 respectively. The L* value is decreased in 68.37-77.48 that lightness is the lowest. The a* and b* value are identified the highest value, when both value is analyzed to identify E* and C* value is still highest. In addition, the study reveals that the concentration of alum at 0.3%, which is used in dyeing of fixing agent, can dye very well because the L* identified lowest value and the a* and b* are highest value. Alum, furthermore, which was calculated to find the C*, identified highest value in 17.076-17.308. For the period of time in suitable dyeing with a proportion of betel nut, red lime and Piper betel Linn, it reveals that every period for dyeing in cotton demonstrated the low value of the L*.
