The objectives of the study titled “Dialect Preservation and Transference : Lao Khrung Dontoom District Nakhonpathom Province” were 1) to study about Lao Khrung language in Dontoom Nalon Pathom 2) to collect the local language information and to write manual “How to study Lao Khrurng?” for schools and other educational institutes in Dontoom Nakhon Pathom. In addition the project aimed 3) to conserve inherit and distribute Lao Khrung to remain in the society with qualitative research methodology. The scope of this research was at Ban Tung Phak Good Dontoom Nakhon Pathom (Lao Khrung Community area). The findings showed that the local language “Lao Khrung” was similar to the voice of Laotians in Luang Pra Bang which was the original homeland of Lao Khrung people in Dontoom. The written forms or alphabets could not be found in Lao Lhrung it had only the spoken language for communication. The sounds in Lao Khrung changed in many ways such as Sound Change Metathesis Sound Shifi Deletion Addition and Assimilation. Lao Khrung language was divided into 10 types including day time number animal flower tree vegetable and fruit characteristic body disease relatives occupation cloth decorations and miscellaneous. The study found that Lao Khrung had different consonant sounds tones words sentences and final particles from other Laotian people who immigrated into this area at the same time. Especially the final particles were much contrastive; they were used as a question a request and an affirmative sentence in the same sentence. Which type of these sentences were used depended on situation intimate status seniority respect social status intention mood and context in each conversation. Transmission inheritance and remaining of Lao Khrung resulted from learning from parents grandparents and elder people from daily routine being familiar with communication and practicing by imitation. The findings showed that conservation and inheritance of local language should be supported restored preserved to study and to collect the information of local language in order to stimulate local people to realize the importance of local language; the local course should also be made. Additionally the local scholars’ capabilities should be developed and supported to express out. Thus the inheritance restoration and transmission to the next generation help preserve and remain Lao Khrung in the Lao Khrung community onwards.

This research had an aim for studying the printing process of LACCIFER LACCA KERR. (LAC) on cotton and polyester fabric. The Lac dye was extracted by using Sodium hypochlorite solution Sodium hydroxide Hydrogen peroxide and diethyl ether then Acetic acid was used for dye sedimentation. Thenthe printing condition and color fastness to washing crocking and light were examined. The efficiency of solution for extraction process were found Diethyl ether > Sodium hypochlorite solution > Sodium hydroxide > Hydrogen peroxide respectively. The hot air was suitable fixation process for cotton and polyester printing. The cotton fixation was 150oC for 5 minutes it is 11.87 in color strength. And the polyester fabric was fixed at 220oC for 3 minutes the 8.27 color strength was shown. The both of cotton and polyester were printed with Lac dye had the good color fastness to crocking and light and moderate in washing fastness. This study can apply the Lac dye on cotton and polyester fabric by a printing technique without mordanting. Then it can reduce some chemicals in the textile printing industry. This process can applied and transfer for small enterprise for Lac value added appication.
