This research Designing and Textile Materials Decorating for Apparels with Film Innovation. The objective is to study the use of film innovation and finishing materials for textiles. To design and decorate costume products with innovative films. This is a great way to showcase your knowledge and technology design and decorate your textiles for innovative costumes. The research instruments were 3 product designs and a satisfaction questionnaire for trainees. The samples used in the research were 12 randomly selected randomized individuals at the Faculty of Home Economics. Rajamangala University of Technology Phra Nakhon By analyzing data To find the average and average values. Summarize results in tabular form. And writing The tools used to collect data were: 1) three types of costume design namely jacket and skirt 2) three types of costume designs 3) On August 13 2018 at the Faculty of Home Economics Rajamangala University of Technology Phra Nakhon. 1) Film innovation The material is made of polymer. Chemical composition Polyvinyl alcohol It is a thermoplastic with special properties. Biodegradable And fire like paper. It can also be dissolved in water. The embroidery machine is easy to emboss but does not make the fabric thick or hard. Embroidery Machine And its easier to pull off than paper. When embroidered. When to use the costume can be washed normally. Because the film will react with the decomposition of the film with water. By soaking the warm water. Allow the film to dissolve for 15 minutes. 2) Design and decorate the costume products with innovative film. Then 3 innovative products were developed namely shirt jacket skirt. 3) Technology Transfer A workshop was held on August 13 2018 at the Faculty of Home Economics. Rajamangala University of Technology Phra Nakhon Most participants were satisfied at the highest level in all questions.

This research has been studied and created the ceramic armor plates with composite materials that been proceeded from drying compression process with mold. Al2O3 that use for compression forming has been analyzed by SEM and XRD. It showed that compound and powder particle led to 5 microns-sized. It had flat circle shape of colundum Al2O3 and hexagonal crystal system. Upper punch of molding has designed and analyzed by FEA to 2 forms first form was the end-point had flat face and second form was the end-point had a convex. Upper punch had been made from AISI 52100 with 64 HRC ceramic armor plate had been produced by compression at 1000 kN which had hexagon side shape of width 25.98 mm for each side or height between parallel side of 45 mm. Al2O3 had been compressed to investigate the distribution of relative density for the height after compression of 15 and 30 mm by analyzing 4 cases that consist of 1.) a case of smooth face of upper punch which has green compact of 15 mm height 2.) a case of convex face of upper punch which has green compact of 15 mm height 3.) a case of smooth end face of upper punch which has green compact of 30 mm height 4.) a case of convex face of upper punch which has green compact of 30 mm height. The result of this study is to propose the distribution of relative density on horizontal axis as it is a relative radius and vertical axis is a relative distance from the upper punch that is an axis of moving down action. This study found that the distribution of relative density form had analogous form for these 4 cases the density had few differences and had high value at the town edge of green compact due friction between die wall and upper punch. The ceramic armor plate has been set up on UHMWPE fiber plate and used special silicone to connect them together then will get the NIJ 3 standard of ceramic armor plate with Composite materials

Quality control of dyeing and finishing of Water Hyacinth yarns and their transformed materials for commercial was a main objective to establish the dye database of synthetic dye and natural dye. The dye database was a data for quality control in dyeing process of raw material as Water Hyacinth yarns also it resolved the un-repeatability dyeing problem. Reactive dye was used for synthetic dye database creation on dry Water Hyacinth yarns at 80oC for 30 minutes. Red as Hicion Red He-3B yellow as Hicion Yellow HE-4RN Blue as Hicion Navy Blue HER 150% and black as Hifix Black KNN were the represent synthetic dye and Sodim sulphate 20 g/l and sodium carbo nate 20 g/l were used as auxiliaries. The other hands the natural dye database was forming from Ebony tree Caesalpinia sappan and Turmeric. They were dye on dry Water Hyacinth yarns at 80oC for 30 minutes and Sodim sulphate 20 g/l was the auxiliary. Whereas Butterfly pea were dye at 80oC for 30 minutes by Sodim sulphate 20 g/l and sodium carbonate 20 g/l were the auxiliaries. The whole dye database was defined the totally in Primary Secondary and ternary dye cycle. The transfer knowledge was distributed to the enterprise at Nakhon Prathom Provincd as “Chumchonjaksanpaktobchawha Bann klongnokkratum”. The topics were “How to establish the synthetic and natural dye database” “Water repel lent finishing” and “developed and transformed the Water Hyacinth to products”. The target group was very satisfied in this topic as 4.39. In the result the proportion between economic and social factor by the income increasing in 1 year was 5.04. So the research project was achievement.

Utilizing coconut coir fiber can offer an alternative method of adding value to agricultural wastes and help to conserve the environment. The aim of this research was to investigate the potential use of coconut coir fiber as cement composite as an environmentally material. The properties of cement composites mixed with different proportions of paper wastes were compared with ordinary white Portland cement. In addition the surface structure and chemical characteristics of samples were examined by a scanning electron microscope (SEM) and energy dispersive x-ray spectrometer (EDS). The results show that the main elements - C O Ca Al Si and K respectively were found in cement composites. The compressive and flexural strength of the cement composite decreased with an increase in the coconut coir fiber volume fraction.

This paper presents the packaging design of the straw material replacement process. For environmentally - friendly products Product Case Studies MAZMOIZELLE Shop Due to the awareness of the environmental problems that affect the lives of all living. The weather is changing. One solution is Eco-design (Economic & Ecological Design) which plays an important role in the production process. Environmental concepts are added to the design process to develop environmentally friendly designs. The sample consisted of the research instruments used in this research were 80 persons. Pre-design questionnaire the questionnaire evaluates the satisfaction of the packaging structure for the environment. Data were analyzed using percentage analysis. The results are evaluated by experts and experts in three aspects: packaging graphic and marketing. The instruments used in the research were questionnaires and satisfaction questionnaires. The results showed that. 89% of respondents agreed to use recycled materials for packaging. The evaluators have a need for environmentally friendly packaging by developing robust packaging. Product Protection And graphics on the beautiful packaging. This shows that packaging is environmentally friendly. And the evaluator needs the uniqueness of the product for the environment. The results of the study concluded that the design of the structure and graphics on the packaging for the environmental products of the five structures from the MAZMOIZELLE product include the packaging for the camera strap. Sack bag Packaging for documents A5 packaging for wallets and notebook bag packaging very good. Packaging can protect the product well and easy to use. Graphic design on packaging that represents a unique identity for environmental conservation. And the results of the replacement test with rice straw mixed grain. Seeds can be grown at a rate of 70% which is good.
