Quality seams have great impact on the quality of garments. The study evaluated effect of laundering on plain seam in a suitable fabric for Ghanaian public basic school uniforms by varying sewing thread and stitch density to establish suitable ones for the achievement of quality in school uniforms. A total number of 290 specimens were used. Washed specimens were subjected to three cycles of washing using Launder-Ometer (Gyrowash 315) and seam strength, efficiency and elongation were evaluated. Means of the attributes were determined and analysis of variance at 0.05 alpha level are used for hypotheses testing. Sewing thread brand B in 14 stitches per inch (spi) provided greater seam strength, efficiency and elongation before and after washing.

Background: The serviceability of a sewn garment is influenced by the quality of its seams, which form the basic structural element. The factors that affect seam quality in garments includes, sewing thread type and stitch density. Their right choice helps with the achievement of quality seams in garments. However, the choice of suitable sewing threads and stitch densities for particular fabrics can only be determined through testing. Objective: Problems associated with poor performance of school uniforms include seam failure. The aim of the study was to determine sewing thread brand and stitch density suitable for seams for a selected fabric (79% polyester and 21% cotton) for Ghanaian public basic school uniforms. Method: A 2×3 factorial design was employed which involved two brands of sewing threads labelled Aʹ and Bʹ and three range of stitch density, 10, 12 and 14. The total number of specimens prepared from the selected fabric was 81. The parameters investigated included fabric weight, strength and elongation, seam strength, seam elongation and efficiency. The data were analysed using the Predictive Analytic Software (SPSS). Means and standard deviations of the fabric’s yarn count, weight, strength, elongation and the linear density of the sewing threads were determined. Analysis of Variance and Independent samples t-test at 0.05 alpha levels were employed in testing the hypotheses. Results: Differences for seam strength, efficiency and elongation were significant for the two sewing thread brands and the three stitch densities in both warp and weft directions of the fabric sample. The sewing thread brand B′ with stitch density 14 performed best in terms of seam strength, elongation and efficiency. Conclusion: The sewing thread brand B′ and stitch density 14 are recommended to be used for the construction of uniforms with the selected fabric to achieve quality in uniforms.

End Uses

The determination of the suitability of fabrics for specific end-uses require the subjection of selected fabrics to conditions they would be exposed to during use and care such as washing. Three different brands of fabrics commonly used for Ghanaian Basic School Uniforms and  labelled A, B and C were evaluated after washing to suggest suitable fabric(s) to be used to achieve quality in uniforms. Specimens were subjected to three washing cycles and strength, elongation, dimensional stability and colourfastness tested. Data were analyzed using the Predictive Analytical Software for windows version 22. Means of the performance characteristics of the fabrics were determined and hypotheses were tested using analysis of variance at 0.05 alpha level. Washing had effect on the parameters investigated. In all, fabric brand B performed best as throughout the wash cycles, its strength values were above the standard requirements set by the Ghana Standards Authority for uniform fabrics. Since the fabric brand B performed best with the parameters investigated, it is suggested for use as school uniform fabric. However, further studies can be conducted on these same fabrics where other parameters such as absorbency and abrasion resistance can be evaluated.

Seam strength plays a very important role in acquiring the desired quality seam which ultimately defines the quality of any clothing. The paper is aimed to study the strength of seam produced from denim fabric, how different sewing parameters like sewing thread type, type of seam, seam direction as well as the density of stitches influence the strength of seam, and it is observed that they have direct effect on lockstitch seam strength of denim fabric with various degree. For research denim fabric with 3/1 weaves structure and three different sewing threads namely 100% cotton spun with 14tex linear density, 100% polyester spun with 24tex and 60tex linear density were used. Seam class used for the research was superimposed seam prepared with two layers, SSa and three layers, SSb. The samples were made by stitching with lockstitch sewing machine both in warp and weft way. Three different stitch densities were used to sew the samples and they were-7, 9 and 11 stitches per inch. The strength of the produced seams was tested on a universal strength tester machine-the titan tensile strength tester. Test was performed according to ASTM D5034 test method. The outcome of the research shows that seam type, seam direction, thread types, and stitch density have direct effect on lockstitch seam strength of denim fabric with various degrees. Higher seam strength was obtained for the SSb type seam produced in warp direction with coarser sewing thread (60tex) and 11 stitches per inch (SPI). The influence of independent variables on the seam strength was assessed statistically using a multivariate variance analysis (ANOVA) with the help of SPSS software and it was found that they effect significantly. Regression analysis was done to develop the regression equation to predict lockstitch seam strength before production process.

The Impact

Zakat is one of the five pillars of Islam which has a function of faith, social and economic functions. Muslims who can pay zakat are required to give at least 2.5 per cent of their wealth. The problem of poverty prevalent in disadvantaged regions because of the difficulty of access to information and communication led to a gap that is so high in wealth and resources. The instrument of zakat provides a paradigm in the achievement of equitable wealth distribution and healthy circulation. Zakat potentially offers a better life and improves the quality of human being. There is a human quality improvement not only in economic terms but also in spiritual terms such as improving religiousity. This study aims to examine the role of zakat to alleviate humanitarian issues in disadvantaged regions such as Sijunjung, one of zakat beneficiaries and impoverished areas in Indonesia. The researcher attempted a Cibest method to capture the impact of zakat beneficiaries before and after becoming a member of Zakat Community Development (ZCD) Program in material and spiritual value. The overall analysis shows that zakat has a positive impact on disadvantaged regions development and enhance the quality of life of the community. There is an improvement in the average of mustahik household incomes after becoming a member of ZCD Program. Cibest model demonstrates that material, spiritual, and absolute poverty index decreased by 10, 5, and 6 per cent. Meanwhile, the welfare index is increased by 21 per cent. These findings have significant implications for developing the quality of life in disadvantaged regions in Sijunjung. Therefore, zakat is one of the instruments to change the status of disadvantaged areas to be equivalent to other areas.

Introduction: There is a decline in male fertility thus new treatments are needed. Aims: To test the efficacy of a new dietary supplement developed in the USA and registered as a curing drug in Hungary (OGYI). Methods: In a clinical trial 100 men with low sperm quality (spermium count 5–20 M/ml, good motility 10–40%, and adverse shape 30–50%) were examined. Results: Sperm parameters were measured before and after a 3-month treatment and after another 3-month without treatment. This dietary supplement statistically and clinically significantly improved sperm count and motility. In 74 cases this dietary supplement demonstrated a beneficial effect on sperm quality (more than 10% increase in sperm count, or quality of motility, or shape); in 16 cases the improvement exceeded 30%. No adverse effect could be accounted for this treatment. Conclusions: This new dietary supplement may contribute to the treatment of male infertility. Orv. Hetil., 2012, 153, 1787–1792.
