การใช้ประโยชน์จากน้ำแช่เมล็ดถั่วดำแห้งในกระบวนการย้อมสีสิ่งทอ

The purpose of this research was to investigate the use of soaked black bean water and to add value to it otherwise it is considered as colored waste water. The soaked black bean water was analyzed for phytochemicals and dyeing process was carried out silk cotton and polyester fibers. Dried black beans were soaked in water ratio 1:1 for at least 12 hours. The dyeing process involved soaking the fiber in soaked black bean water at 100o for 30 min. to determine the type of fiber staining and color fastness. Results showed presence of Anthocyanin Anthraquinonoid Terpenoid Saponin Tannin and Flavonoids in soaked black bean water. It was found that dye could be absorbed by silk fabric in an acidic condition. The shade appeared red-brown at L*44.17 a*16.88 and b*20.13 color strength was 6.19 and ultraviolet protection was blocked more than 97.5 percentages as UPF 50+. Moreover the color fastness grading in crocking property was very good to excellent (CF 4-5) good washing fastness (WF4) and moderate fastness in the presence of light (LF 4). In conclusion soaked black bean water can be used for dyeing for silk fabric and enhance UV protection.

Nowadays one of the automotive engineering is conductivity of brake pads playing a role in friction coefficient which means safety of customer. Thus thermal properties have been improved using composited materials. This project aims to study the heat capacity behavior of 3 different brake pads which are supported by the company Compact International (1994) Ltd. For experimental works temperature based on brake condition was simulated from 05 to 003°C at 5 MPa of pressure. By standard JIS D4413 testing condition of pressure was referred. The heat capacity values of brake pads are calculated under the temperature conditions. As a result of testing brake pad made of copper or high metal powders result in relatively low heat capacity. On the other hand brake pads containing fiber and a large amount of fillers result in an increased heat capacity and stability in various temperature conditions. The heat capacity varied according to the operating temperature. In addition the lubricant contained in the brake pads affects the higher heat capacity and stability at various temperatures.

Nowadays one of the automotive engineering is conductivity of brake pads playing a role in friction coefficient which means safety of customer. Thus thermal properties have been improved using composited materials. This project aims to study the conductivity behavior of 3 different brake pads which are supported by the company Compact International (1994) Ltd. For experimental works temperature based on brake condition was simulated from 200 to 400°C and cooled down from 400 to 200°C at 1 5 and 8 MPa of pressure respectively. By standard JIS D4413 testing condition of pressure was referred. The non-linear of conductivity value are calculated from the temperature under steady state condition. As a result of testing there are several of parameters effecting on the non-linear conductivity value. The brake pad that is a mix of high-fiber affects the fluctuation of thermal conductivity. At the same time lubricant in the brake pad cause the stability of conductivity value in different temperature range at the same pressure. On the other hand the brake pad mixed hi-copper inspires the narrow range of conductivity value in different pressures at the same temperature. Moreover the conductivity value as a mention is inversely proportion with the coefficient of kinetic friction.

The purpose of this project is to produce a versatile sewing table for the shirt room. To explore user satisfaction The sample group used in this experiment was 10 garment sewing business operators with the sample group being able to use the multipurpose sewing table for the shirt room for 3 days. The questionnaire evaluated the satisfaction with the use of the table. Multi-purpose sewing for the shirt room. Statistics that use frequency percentage mean standard deviation The results of the satisfaction evaluation in the size and materials that are suitable for use found that the use of suitable materials for use is satisfied at a high level with an average of 4.8 a versatile sewing table is appropriate. For use at a high level with an average of 4.5 The structure of a versatile sewing table is strong with an average value of 4.1 The useful side in the use of a versatile sewing table helps increase the space. In which the work is satisfied at a high level with an average of 4.8 the use of appropriate level adjustment satisfaction is at a high level with an average of 4.5 applications can be an accessory to create patterns The satisfaction was at a high level with an average value of 4.5 Convenient foldable use was satisfied at a high level with an average of 4.4 Usage can be an accessory for paving and cutting cloth. Not With satisfaction at a high level with an average of 4.4 The beauty of the versatile sewing table is beautiful suitable is satisfied at a high level with an average of 4.8 bars the main measurement unit inches and centimeters are the font size. And the color is clear beautiful suitable satisfied at a high level with an average of 4.7 the format and size of a versatile sewing table is beautiful suitable satisfied at a high level with value Average 4.4

The purpose of this project is to design and tailor a multi-purpose artificial fur coat for women and to evaluate the satisfaction of a multi-purpose artificial fur coat for women consisting of a long fiber artificial fur coat. And two short fiber artificial fur coats. Asked about the satisfaction with the versatile artificial fur coat for students of Rajamangala University of Technology Phra Nakhon. Faculty of Textile and Fashion Design Department of Clothing Technology Between grade 1-4 number 40 statistics using frequency values percentage values mean standard deviation The results of the study of two sets of versatile fur coats for women namely long-fiber artificial fur coats and short-fiber artificial fur coats were found in 40 respondents. On each side it was found that in the form of both products the design was at the highest level with an average of 4.60 and the suitability of the product was at the highest level with an average of 4.55 respectively.
