    Antimicrobial studies of knitted fabrics from bamboo, soybean and flax fibers at various blends
    (Textile Science & Engineering, 2015) Muhammad Qamar Tusief; Nabeel Amin; Nasir Mahmood; Israr Ahmad; Mudassar Abass
    In the current study, the single jersey knitted fabric from natural fibers bamboo (Dendrocalamus strictus), soybean (Glycine max) and flax (Linum usitatissimum) at various blend ratios are prepared for comparison of physical strength and antimicrobial properties. For the general characteristic evaluations it is deduced that the fiber strength of pure flax is comparatively stronger than bamboo and soybean, whereas the antimicrobial properties of the bamboo fibers are the highest. Therefore, the blended fabric with multiple compositions for these three fibers is prepared and compared with the fabric made from individual pure fibers. In sum, the blended fabrics showed enhanced results for both antibacterial activity and strength, where the strength of flax/bamboo blended fabric with equal ratios (50/50) at higher twists and antibacterial activity of soybean/bamboo blended fabric with blend ratio 10/90 was found the best as compared to other combinations.

    Effect of different processing stages on the crystallinity % and tensile strength of 100% cotton fabric.
    (Pakistan Journal of Science and Industrial Research., 2015) Nabeel Amin; Mudassar Abbas
    In this study, 100 % cotton fabric was used to check the impact on fabric crystallinity and tensile strength at different processing stages. Desizing, scouring, bleaching, mercerization and resin (only resin & resin+softener) application were the processes performed on the fabric. X-Ray diffractometer and tensile strength tester were used to determine the crystallinity index (CI) and tensile strength, respectively. Results revealed that from scouring to mercerization crystallinity (CI) decreased while desizing and resin application treatments showed no significant impact on the crystallinity (CI). In case of tensile strength, a decreasing trend from desizing to resin application was observed.

    Fabric tensile strength as affected by different anti pilling agents at various concentration and PH levels
    (2013) Muhammad Qamar Tusief; Nasir Mahmood; Nabeel Amin
    Pilling is a phenomenon that has a long cause trouble in textile industry. It is the formation of pills or knops on the surface of woven or knitted fabrics caused by friction and abrasion. If fabric has a pronounced tendency to pilling, their appearances suffer severely after a short period of use. The pilling of fabrics is a serious problem for the apparel industry. The use of anti pilling finishes is one of the best techniques to control the pilling of the fabric. In this method fabric is treated with special anti pilling agents to prevent pilling that promote adhesion of the fibres in the yarn or the fabric. This paper endeavors to optimize the application of different anti pilling agents at different concentration and pH levels on the Tensile Strength of P/C fabric for best results. The results exposed that different anti pilling finishes have significant effects on the Tensile Strength of fabric at different concentration level however different pH levels have no considerable effects.

    Impact of various wrinkle free finishes on wrinkle recovery property of cotton fabric under different variables
    (Textile Science & Engineering, 2014) Tusief MQ; Mahmood N; Nabeel Amin; Saddique M
    Today everybody wishes for that his/her dress retains just ironed shape. Wrinkle free finishes provide wrinkle free and soft look fabric. Wrinkle free finishes are broadly used in the textile industry to impart wrinkle-resistance to cellulosic materials such as cotton fabric. The application of wrinkle resistance (permanent or durable press) finishes on the fabric improves their wrinkle resistance property. Because of increasing demand for pure cotton fabrics, permanent press finishes are being used on these clothes. In conventional durable press finishing, there are two types of products used (resin type and reactant type). Both of these products contain formaldehyde which cause human carcinogen. Hence durable press finishes free of formaldehyde with trade namesTexicil DC, Knittex RCT, Arkofix NEC and Arkofix ELF (Dihydroxi ethylene urea and Demethyldihydroxi urea) were used in this research study. The present work endeavors to optimize the application of these wrinkle free finishes at various concentrations trying different techniques of applying these finishes on pure cotton fabric for best manufacturing results. The results revealed that the finish Arkofix ELF and Arkofix NEC showed superior results at the concentration level 120 g/l under Pad-flash –cure method of application for the wrinkle free property of the fabric.

    Tensile properties of cotton yarn as affected by different yarn singeing machine variables
    (Series A: Physical Sciences, 2014) Muhammad Qamar Tusief; Nabeel Amin; Nasir Mahmood; Waqar Iqbal
    The present study endeavours to optimise the yarn quality in respect of its tensile properties by choosing the best combination of the yarn singeing machine variables for excellent manufacture results. This research study revealed that different values of winding speed, gas pressure and air pressure of yarn singeing machine put significant effect upon the tensile properties of cotton yarn after singeing.
