การทดสอบประสิทธิภาพระบบการพิมพ์พื้นนูนและการพิมพ์พื้นฉลุบนวัสดุจากเยื่อธรรมชาติเพื่อพัฒนาเป็นบรรจุภัณฑ์ที่เพิ่มมูลค่าและการใช้งานในเชิงพาณิชย์
This research is to study and develop natural pulp materials for packaging. This is the agricultural waste. To benefit commercially To build capacity and capability in economic development and environmental conservation Is the creation of packaging work Formed in sheets and shapes using natural materials such as mulberry paper pineapple paper. And banana paper Then design and create the packaging. To test the properties. According to the standard packaging. They also sought satisfaction in the form and use of natural pulp materials. Include the packaging according to the case study. Research indicates that When developing pulp quality The banana paper can not be printed. Can print lines. But screen printing is not suitable for banana paper. Foil printing case when mulberry paper and pineapple paper Foil printing Printing lines Can be done well on mulberry paper and pineapple paper. Death images can be printed on all three types of paper but the screen is not good. Sealing material from natural pulp onto corrugated paper. From the test it was found that the amount of adhesive that was suitable for sealing was between 20-30 mg. If the adhesive was less than 20 milligrams only mulberry paper was sealed. The amount of glue at 50 milligrams is the amount of glue is too high causing all three types of paper to rot. Because of the adsorption of glue to the pulp. Packaging material from natural pulp. Fold of banana paper that does not pass the test. The banana paper is high in strength. When folding the packaging causes the pulp to split along the crease. Can not be molded. Evaluation of the satisfaction with the form and use of packaging materials from natural pulp. It was found that the average value of paper pulp suitable for packaging materials from natural pulp was the most agreeable paper. Secondly paper shreds are very popular and the last one is banana paper. Moderate agreement
การพัฒนาสารกั้นสีจากแป้งที่ได้จากหัวบอนเพื่อใช้ในการพิมพ์ย้อมผ้าแบบรีซีสต์
The purpose of this research was to study the white resist printing with colour resistant material from flour of wild taro (Colocasia Esculenta (L.) Schott) and using reactive pigment and natural dyes as dyestuffs. Five formulas of printing pastes were applied to light cotton thick cotton and silk fabrics by the use three techniques nauely Silk screen (White resist and colour resist methods)stencil and batik. The optimal ratio of colour resistant materials from flour of wild taro were compose of 20 grams flour of wild taro 32-36 ml. water 30-34 ml. sodium chloride 10-13 ml. calcium hydroxide and 1-4% vegetable oil. The viscosities of printing paste from five recipes were shown in the rage between 559.9-671.9 Centipoise. All five recipes can resist dyestuffs and also easy to remove the flour of wild taro. The pattern at resist printing area of fabrics shows sharpness and whiteness. The colour fastness to washing water and perspiration on cotton and silk fabric results were ranging between poor to fair level when using reactive and natural dyes as dyestuff. However the fastness property of pigment dye shows medium to good level. The colour fastness to rubbing is shown to be in range of 4 to 4-5 for all recipes. The ratings of colour fastness to light in terms of colour change are fair to good (4 to >6).
