2.2 education processes in the production of natural fiber sponge from water hyacinth study study the proper condition by studies of water hyacinth RID Li nalaeo come on each pattern on sodium hydroxide soak concentrated 4, 6, 8 and 10 in the ratio by weight of a substance per pattern crochet per sodium hydroxide equals 1.5, 1:10 1:15 and 1:20 at 30, 50, 70 and 90 degrees Celsius for a period of 30, 45, 60, 75 and 90 minutes, and study suitable for producing natural fiber sponge. The trial will use a proportional quantity of cellulose in mixed nuet's 3, 4, 5 and 6 and sodium sulfate in the ratio by weight of compound sodium sulfate 1 nuet here: 1 and 1:2 and then enter 5 mm long fibre Typha 1-2 per cent by weight of the mixture nuet.2.2 comparison of the efficiency of digestion with natural fiber sponge sponge in the market.Made with natural fiber sponge to apply the sponges on the market ground with the moisture of the Earth, approximately 65 per cent, to degrade every 5 days for a period of two months by percent of digestion.
