The aim of this reseach in to paint on silk fabric with batik technique using five natural dyes from neem tree bark lac mango leaves marigold and star gooseberry bark. The pre-mordant and after-mordant techniques were used in this work. There were 10 Mordants Aluminium Potassium Sulfate Copper Sulfate Sodium Dichromate Tannic Acid Tartaric Acid Tin (ll) Chloride and Calcium Acetate-Monohydrate were applied. The batik fabrics were characterized In color strength rubbing fastness washing fastness light fastness and stiffness. The result-indicated that silk Fabric painted with natural dye from neem tree bark could use all 10 mordants to improve color strength and gave various shade of color. The silk fabric painted with Natural dye from lac could not use all 10 mordants to improve color strength but it gave various shade. The silk fabric painted with natural dye from mango leaves marigold and star gooseberry bark showed that almost 10 mordants gave higher color strength and various shade. The mordanting technique would give good fastness and reduce the stiffness of batik fabric.

Devlopment of Screen Printign Devices Prototypes for Textile lndustry was a research project which it was established to solve the practical learning of the faculty of industrial textile and fashhion desing students at Rajamangala University of Technology Phra Nakhon. This set had 3 important machines such as a self assembly aluminum block screen an automatic aluminum screen could saved the saved the screen fabric1.76 m2 reduced the chemical usageand waste minimization in the process.The practical time reduced from 16 minutes to 1 minute using the automatic aluminum screen coating. The efficiency time was 97.81. The 400 gram emulsion consumed obtained the thin film layer on the screen fabricand evenness.The sharpen pattern displayed when the exposed time was 3minutes.Moreoverthe drying and fixation machine was completely for natural fiber and synthetic fibers at 80-180 C. Therefore the Screen Printing Devices Prototypes was effectively used in textile industrialdispose of the practical learning problemraw material savingand waste minimization adjacent to clean technology process.The prototype set was produced by house equipmentsand extended for textile industrial.

Cooling water recovery from water distillation equipment was a research that has the objective to restore the cooling water from distillation equipment which installed at textile chemistry technology department laboratory at Textile industrial and fashion design in Rajamangala University of Phra Nakorn. The research plan was designing and developing the water distillation equipment type cyclon ultrapure water stills model WSC008 of Fistreem company. The outcomes found the designed system could save the tap water consumption 3462.72 square meters per year. That was implied 7617.64 Bath per year of tap water consumption could be save what the tap water consumption rate was 2.22 Bath per square meters. This system was paid back in 3.33 years and the benefit-cost ratio for single project (B/C ratio) was 1.26 (>1). Finally this project was successfully to save the tap water consumption and great benefit investment.

The aim of this research is to paint silk fabric with batik technique using five natural dyes from margosa bark lac mango leaves marigold and otaheite gooseberry bark. The pre-mordant and after-mordant techniques were used in this work. Ten mordants Aluminum potassium sulphate Copper (II) sulphate Sodium dichromate Tannic acid Tartaric acid Tin (II) chloride and Calcium acetate-monohydrate were applied. The batik fabrics were characterized in color strength rubbing fastness washing fastness light fastness and stiffness. The result indicated that silk fabric painted with natural dye from margosa bark could use all 10 mordants to improve color strength and gave various shades of color. The silk fabric painted with natural dye from lac could not use all 10 mordants to improve color strength but it gave various shade. The silk fabric painted with natural dye from mango leaves marigold and otaheite gooseberry bark showed that almost 10 mordants gave higher color strength and various shade. The mordanting technique would give good fastness and reduce the stiffness of batik fabric.
