The aim of this research is to investigate the strength properties of cotton polyester blended woven fabrics of different fiber content. Strength is directly related to the polyester content percentage of the cotton polyester blended woven fabrics. This research proved that strength is enhanced when the polyester content proportion is enhanced in the fabrics and vice versa. Three different nomenclatures of cotton polyester blended woven fabrics of different composition were collected from fabric mill and the required strength tests were carried out in agreement with ASTM D2261 Standard (tear) and ASTM D5034 Standard (tensile). It is a practice based research and the findings may be beneficial to the personnel involved in textile industries who are responsible for the manufacture of cotton polyester blended woven fabrics and to control of their strength properties. This research proved that the values of strength depend on the polyester composition percentage of cotton polyester blend in the fabrics and it opened suitable ways for the intellectuals to further study in this field.

In today’s global world the importance of filtration is become necessary in our day to day life as the rapid development of the countries all over the world causing pollution in the environment. Separation of insoluble substance from a fluid, by allowing it to pass through a porous material is called filtration. For filtration of air and water different technology has been implemented and continuously improving the quality of filtration day by day. This paper leads to use of filter cloth on different processes and will make the clear understanding on the factors that directly or indirectly influence of the quality and quantity of filtration using different kinds of filter cloth.

This paper aims to scrutinize the change in physical and chemical properties of cotton knitted fabric with a variety of shade depth (1% to 8%) dyeing with reactive dyes. Shade percentage is an important factor which has various impacts on 100% cotton knitted fabric. The technical factors of GSM, color fastness to rubbing, bursting strength test, color fastness to wash, and color fastness to perspiration of cotton knitted fabric are influenced by various shade percentage (1% to 8%). The cotton knitted bleached fabric which was dyed with Remazol Red RR reactive dye and auxiliaries with different shade percentage, then measured GSM & their fastness properties. It was observed that after increasing the shade percentage on cotton knitted fabric, GSM was increased but bursting strength is decreased. On the other hand, color fastness to rubbing, wash and perspiration is decreased repeatedly.

Sewing process is one of the most important stages in labor intensive ready-made clothing enterprises. Quality faults occurring during this process adversely affect the product quality and product efficiency, and also increase the production cost. The aim of this study is to investigate whether the knitwear production process is under control in a knitwear production enterprise and to detect the processes with highest rates of sewing faults in sewing department and finally to make suggestions for improving the quality control. Among the Statistical Process Control methods; control list, product control chart were used in the study. “Product control chart” was used to test whether the production process is controlled in the enterprise. Furthermore, the statistical methods were employed to determine the issues that need to be done in the improvement efforts and to detect the relations between the process groups supposedly effective on faults occurring in knitwear production and the amount of faults. Also, the processes with highest amounts of sewing faults and the effects of these processes on fault rates were investigated. As a result, it was concluded that the production process was statistically not under control in the ready-made clothing enterprise. In addition, this study demonstrated that the investigation of each process group by drawing their product control charts would make significant contributions to foresee the results and prepare more effective the improvement plans.

A novel approach to indexing eye tracking metrics was used to evaluate selected student apparel designs prior to an annual student fashion show at a large Midwestern university. Participants were asked to focus on areas of six garments that they believed were innovative. Eye tracking data including fixation and gaze metrics were then compared in 60 pairwise combinations and 240 image ranges. Significant differences in pairwise combinations of raw eye tracking data were found and these incidences were then aggregated to create an index of factors of perceived garment innovativeness.

The general objective of the study was to look at the challenges facing garment producing industries under AGOA in Ghana. The study was conducted using 116 workers from four garment producing industries in Accra and Tema. Questionnaires and interview schedules were developed and used to collect data from the sampled workers. Statistical techniques such as means and percentages were used to analyse the data collected. The industries and workers have major challenges such as lack of motivation, inadequate facilities and amenities, lack of funding, and insufficient managerial ability. Strategies that will help improve operations in the industries were mentioned by workers and this were grouped in two i.e. welfare and factory running. The following recommendations were made: 1. The Ghana Trades Union should monitor the industries and make sure the workers are duly paid for what they work for and on time. 2. The Government should help the industries financially or help them assess loans or the US credit facilities that will enable them acquire modern equipment and pay their workers well.

Geotextiles particularly refers to permeable fabric or synthetic material, woven or non-woven, which can be used with geotechnical engineering material. They apply to a broad range of civil engineering construction, paving, drainage and other applications. Geotextiles are extensively used with soil, rock, earth or any other geotechnical engineering-related material. In any one application, a Geotextile may be performing several of these functions. In Erosion control, the Geotextile protects soil surfaces from the Tractiveforces of moving water or wind and rainfall Erosion. On the other hand a Geotextile serves to control Sediment when it stops particles suspended in surface fluid flow while allowing the fluid to pass through. After some period of time, particles accumulate against the Geotextile, reducing the flow of fluid and increasing the pressure against the Geotextile. On the whole this paper discusses the roles of Geotextile in Erosion and Sediment control.

The alkaline fractions of banana peel (Musa, cv. Cavendish) of fruits have been used as a natural dye for cotton fabrics. In the current study, banana peel was evaluated as a multi-functional antibacterial and UV protective agent on the cotton substrate. The extracted solution using 0.1% NaOH was analyzed by high performance thin layer chromatography (HPTLC) analysis technique. The extracted dye was applied to the premordated bleached and mercerized Egyptian cotton fabrics made from Giza 89 and Giza 80 cotton varieties. Ferric sulphate was used as mordent. Antibacterial activity was analyzed qualitatively in terms of zone of inhibition and quantitatively in terms of percentage reduction in bacteria. Dyeing performance in terms of color parameters K/S, L*, a*, b* and ΔE were studied. Effectiveness of banana peels against ultraviolet radiation was evaluated in terms of ultraviolet protection factor value (UPF). The data obtained showed that the mercerized fabrics have excellent antibacterial activity, high dye uptake with high UV protection properties among the control and the unmercerized cotton fabrics. The data obtained revealed that Giza 89 had the higher antibacterial activity, dye uptake with high UV protection properties than Giza 80. These results are very important for industrial application with the production of a natural dye, antibacterial, and UV protected as an inexpensive source from waste banana peel as a by product. The optimum treatment and dyeing conditions were applied on 620 g fabric (about 5 m) and matched results were obtained to the research samples.
