Purpose The purpose of this paper is to facilitate the production of cotton spandex woven fabric with some user-friendly properties like wearer comfort, super stretch and elasticity. The findings could contribute to ease spandex production and to optimize its property of elasticity. Stretch or a super stretch property is generally desirable, as it can increase the comfort level of those who wear it. In this experiment, the difficulties which were identified while manufacturing cotton spandex woven fabric resolved after identification. Design/methodology/approach In this experiment, three types of cotton spandex woven fabrics, with different composition and constructions, were used to find out their elastic properties. Temperature ranging from 160°C to 200°C with the machine speed of 20 to 26 MPM (meter per minute) was applied with an adjusted industrial setting with the facilities of a stenter machine to optimize the properties of cotton spandex woven fabric. Findings The findings establish that the temperature treatment closely compacted the elastic portions with cotton fibers, giving stability to the spandex yarn, which as a result, influenced cotton spandex woven fabric’s elastic properties, namely, stretch, growth and recovery. The consequences of temperature on cotton spandex yarns were assessed using a microscope, and the results were subsequently analyzed. Research limitations/implications Because of the poor facilities in testing laboratory, only few tests with microscopic evaluation were conducted to assess the elastic performances of cotton spandex woven fabric. Practical implications It is a practice-based research, and the findings could be beneficial to personnel in the textile industry, who are responsible for the manufacturing of cotton spandex woven fabric. Social implications This research could enhance the wearer’s satisfaction, with some comfort elastic properties, which can have a positive influence over spandex clothing industries. Originality/value This research establishes that heat setting had a progressive influence on the production of cotton spandex woven fabric and for the optimization of its elastic performances. This research opens a possible way for scholars to further study in this field.

An improved design for a combination Scanning Tunnelling Microscope/TEM specimen holder is presented. It is based on earlier versions which have been used to test the usefulness of such a device. As with the earlier versions, this holder is meant to replace the standard double-tilt specimen holder of an unmodified Philips 400T TEM. It allows the sample to be imaged simultaneously by both the STM and the TEM when the TEM is operated in the reflection mode (see figure 1).The resolution of a STM is determined by its tip radii as well as its stability. This places strict limitations on the mechanical stability of the tip with respect to the sample. In this STM the piezoelectric tube scanner is rigidly mounted inside the endcap of the STM holder. The tip coarse approach to the sample (z-direction) is provided by an Inchworm which is located outside the TEM vacuum.

This paper proposes a new conceptual framework in understanding the dynamics within the Kurdish and Turkish (KT) owned firms in London by utilising Charles Tilly’s work concerning collective resource mobilisation. Drawing on 60 in-depth interviews with restaurant, off-licence, kebab-shop, coffee-shop, supermarket, wholesaler owners and various community organisations, the paper sheds light upon the questions of why and how the KT communities in London moved into, and are over represented and why Turkish Cypriots are absent in small business ownership. The re-search illustrates that members of the KT communities aligned in their interests to become small business owners after the demise of textile industry in the midst of 1990s in London. The interest alignment in small business ownership required activation of various forms of capital and transposition of social, cultural and economic capital into one another.

A musculoskeletal disorder is highly dependent on the workplace design. The workers whose job requires repetitive tasks, are more prone to this disorder. Textile industry is one of the labor intensive industries and most of its jobs require continuous engagement with the work. Sewing machine operators in this sector due to workplace design are facing high risk of health issues due to focused attention and static posture of the body. Understanding the health issues linked with continuous working hours and static posture need to be addressed. Both Government and non- government organizations need to be better involved in designing interventions targeting these people and protecting them from such health risks.The present study was conducted in Hisar district from Haryana state in which respondents were selected randomly. Total number of respondents were 60 in which 28 were males and 32 were females with objectives to assess work organization and work space design and to find out the occupational health problems and musculoskeletal symptoms among sewing machine operators. The results showed that maximum numbers of the respondents (68.4%) were took break of fixed duration and (53.4%) respondents were work along with others. Majority (43.3%) respondents were the first experience of MSK symptoms from 7 days to 12 months followed by (33.3%) respondents in 2-3 years.
