This research was concerned about clothes production from remnant fabrics that can increase product value and meet market demand by using patchwork and appliqué technique. The research was conducted into 3 phases : data collecting prototype production and consumer satisfaction evaluation. Questionnaires were used as instrument for data collecting. The first one the researcher inquired; what kind of products that consumer expected to see from remnant fabrics and collected data as market demand in order to produce 9 prototypes by using patchwork and appliqué technique. Finally the prototype was provided to the sample group with the questionnaire in order to evaluate consumer satisfaction toward the prototype. The obtained data from the first questionnaire showed the most of sample was believed that product from remnant fabrics was a low price with poor quality and has no attractive design. The majority of sample interested in apparel product produced from remnant fabrics and sign of the zodiac was selected for decorative pattern. In comparison the result between the first and second questionnaire found that patchwork and appliqué technique could change people attitude toward the product from remnant fabrics. The satisfaction of sample group towards prototype product was ranging in high level. The most of sample group agree to patchwork and appliqué was appropriate technique for transformation and value added to remnant fabric. A price of prototype estimated by consumer was 2001 - 3000 baht per item.

The adsorption of cotton fabric is improved by treatment with sodium hydroxide which is called causticization method. In the method it is necessary to wash off unreacted sodium hydroxide from the fabric and then neutralize with some acids such as acetic acid and sulphuric acid. In this research citric acid was used to neutralize causticized fabric and anticrease finish on cotton fabric. The citric acid is non-formaldehyde anticrease finishing agent. So that the two processes i.e. causticization and anticrease finish could be combined into one continuous process. And it was found that the causticization would improve some properties of anticrease fabric with citric acid. From the result it showed that the anticrease fabric had lower tensile strength than untreated fabric. The anticrease finish with 6% w/v citric acid had higher tensile strength than 8 and 10 % w/v respectively. When concentration of acid curing temperature and time were higher wrinkle recovery angle would be increased. The effect of catalyst showed that anticrease finish using sodium hypophosphite as catalyst was higher wrinkle recovery angle and tensile strength than non-catalyst finish. The causticization before anticrease finish would increase tensile strength and whiteness of fabric when compared to only anticrease finish. The effect of catalyst showed that at low acid concentration increasing of catalyst didn’t have effect on tensile strength and wrinkle recovery angle value. At higher acid concentration trend of tensile strength was decreased whereas wrinkle recovery angle increased and slightly effect on whiteness.

This research aim to improve a combustion system of boiler within increase combustion efficiency and use all out of the energy. The large boilers were used in the industrial factories which consume a lot of energy for production. By oil and gas fuel will be increasing costs everyday cause many factories interested in energy saving with any method technical engineering specifically for production costs and environment effect decreasing. This researching was installed and program was invented in the industrial factory. This industry factory consumed cogeneration energy for fabric dying. The efficiency before installing the software is measured about 65.85 - 71.98% which heat in exhaust gas about 20% of overall energy is filled in the system. After installing heat loss in the system has been fallen until remain about 5 - 12% and efficiency of heat in system has been reached a peak of 80 - 85%.

The effect of grinding on the chemical and physical properties of rice husk ash was studied. Four rice husk ashes with different finenesses i.e. coarse original rice husk ash (RHA0) RHA1 RHA2 and RHA3 were used for the study. Ordinary Portland cement (OPC) was partially replaced with rice husk ash at 20% by weight of binder. The water to binder ratio (W/B) of the mortar was maintained at 110%±5% with flow table test. Specific gravity fineness chemical properties compressive strength and porosity test of mortars were determined. The differences in chemical composition of the rice husk ashes with different finenesses from the same batch are small. The use of RHA3 produces the mortars with good strength and low porosity. The strength of the mortar improves with partial replacement of RHA3 in comparison with normal coarse rice husk ash. The use of RHA3 results in a strong and dense mortar which is due to the better dispersion and filling effect as well as an increase in the pozzolanic reaction.

The purpose of this study is to study the behaviors of undergraduate students in an institution in Khon Kaen province. The results showed that students began to gamble since they were at the secondary school. The causes of football gambling were not only from their desire to cheer up their favorite teams for enjoyment but also they wanted to gain more money that was highlighted as a main factor. This was because they would like to pay for their night life places or to luxurious dotain and expensive items. The main effect of the football gambling was financial problem which linked to endless problems such as stress and depression from losing the gambling pressure from paying back the debt having some mental problems and being afraid of being demanded to pay of a debt. Moreover there were some problems on the relationship among friends because they skipped the classes and some might give up their study due to a huge amount of debt.
