Water Hyacinth Yarns and Their Transformed Materials Dyeing Machine for Developing Small and Medium-Sized Enterprises was a research project what an aim for producing a prototype dyeing machine. The machine was used at the small enterprise in Nakhon Prathom province. The dyeing machine was contributed by stainless steel. The outer dimension was 100 centimeters in height 130 centimeters in length and 90 centi-meters in width. The inner structure contains with perforate stainless steel drum. It had diameter as 80 centimeters with 90 centimeters length. The container capacity was 27 liters for the raw material as 10 kg of the dry Water Hyacinth Yarns or 5 kg of the dry Water Hyacinth roots. The machine was running test for reactive dyeing process at 80oC for 30 minutes. The machine was achieved for reduce time operation as 5 times and gas consumption as 2.38 times. The break-even point was 1.09 year and B/C as 2.22. Moreover it can solve the fuzzy yarns problem and the volatile smoke during the tradition dyeing. The knowledge was transferred to the stakeholders at the target area as “Chumchonjaksanpaktobchawha Bann klongnokkratum” enterprise in Nakhon Pra thom province. They were satisfied in this benefit in good to very good level.

The purposes of this research were to design and create dyed silk yarn and cotton yarn machine for community enterprises of Ban Na Pho woven group Na Pho district Buriram province. All materials were made of stainless steel and the principle of rotation of the yarn skein which was hung with spindle yarn inside the dye tank. Dyeing process began by mixing color tanks in the exterior size for diameter ๓๐๐ mm. Adjust the temperature inside the dye bag by the boiler was attached below. Using pump in dye tank for rotating the heat with stainless steel pipe in ๑๑/๒ inches and ๓ inches x ๑/๒ inches and the rectangular tank was ๖๐ cm. wide ๙๐ cm long and ๑๖๐ cm. high. It had ๕ mm. of plastic lid cover in front of and a channel that looked at the attachment of color yarn. The lid had ๒ levels adjustable lift spring lock and ๒-axis spindle yarn. It was triangular shaped drilled holes spray to ๑ mm. on the spindle with a diameter of ๑๕ cm. and ๖๐ cm. long rotating at ๑๐ rpm strength by using electric motor size ๐.๕ HP used ๒๒๐ volts. It could be rotated left and right with the gear ratios around ๒๐:๑ ๒ adjustable that were automatic with programming on the control box and simple pattern. the spray dyed paint had ๑ liter water pump to control pressure valve for opening and closing to dyed water flow regularly by the heat from the LPG gas with a head size of ๓๐ cm. and adjust the temperature up to ๑๒๐ Celsius degree. It was showed the temperature measurement of water dye with pressure gauge and temperature gauge. The efficiency of this dye can be dyed silk yarn and cotton yarn per ๕ kg. to ๑๐ kg. which was a medium-sized textile production to the local community enterprise and applied in the preparation of yarns before dying such as peeling glue and bleaching.
