Arsheen Moiz,Rajiv Padhye,Xin Wang 한국섬유공학회 2019 Fibers and polymers Vol.20 No.2

Tailoring the surface of fibrous materials has brought special performance to textiles, endowing protection against threats from either environment or in wearer’s daily routine. Different functionalization techniques, including plasma treatment, pad-knife-pad coating and laminating, have been widely used to engineer the surface of fabrics for this purpose. This study contributes a comprehensive comparison of fabrics treated by these different techniques, in terms of surface morphology, chemical components, handle, superhydrophobicity and its durability, and resistance against water, liquid, oil, chemicals and soil. The comfort of the fabrics, including air permeability and moisture management properties, was also analyzed. It has been found that these functionalization techniques brought different levels of versatile protection to textiles with the sacrifice of comfort due to the change of the surface of fabrics.

Rajkishore Nayak,Rajiv Padhye 한국의류학회 2016 Fashion and Textiles Vol.3 No.1

Laser is being used in apparel industry from nineteenth century for various garment manufacturing applications. There are several advantages of using laser over the conventional processes in cutting, engraving, embossing, denim fading and other applications. In addition, product damage potential is reduced, no/less consumables are needed and no problem of toxic by-product disposal as found in some processes. Today’s laser equipment is a result of continuous research and development of earlier products, which has undergone several changes. The initial laser systems were cumbersome, hard to run and difficult to maintain. However, the modern laser systems are simpler in operation and maintenance. Furthermore, the earlier systems were involved with more safety issues and needed the gasses to be constantly replenished. The garment manufactures around the globe should take the advantage of laser application in the post multi-fibre agreement regime to make their products more competitive. This review focuses on the technology of laser including various classifications. In addition it includes the applications of laser in garment manufacturing, their potential hazards and health related concerns.

Functional Dyeing of Cellulose-based (Linen) Fabric Using Bombax Ceiba (Kapok) Flower Extract

Arsheen Moiz,Rajiv Padhye,Xin Wang 한국섬유공학회 2019 Fibers and polymers Vol.20 No.2

Linen fiber, which is claimed to be more comfortable than cotton, is an important textile fiber obtained from Linum usitatissimum (Flax) plant. However, the lack of functional properties of linen limits its application in functional textile products. Nowadays, use of natural colorant for textile dyeing has become an attractive option for sustainable textilecoloration. Kapok flower is an unexplored source of natural dyestuff which can also be utilized for functionalization of cellulose-based textiles. In the current work, kapok flower extract (KFC) was utilized as a functional dye for dyeing of linen fabric in the presence of metallic mordants. The dyed fabrics were evaluated for coloration properties (color values, color coordinates, and fastness properties) as well as functional properties viz. antibacterial activity, UV protection, and antioxidant activity. The satisfactory level of dyeing with acceptable fastness ratings was achieved on linen fabrics. The dyed fabrics displayed an excellent antibacterial activity against gram-positive and gram-negative bacteria. The efficient level of UV protection and radical scavenging (antioxidant activity) was also obtained. The mechanism of functional modification of linen using KFC was discussed.

Effect of Dye Solution Ionic Strength on Dyeing of Cotton with Reactive Dyes

Awais Khatri,Max White,Rajiv Padhye 한국섬유공학회 2018 Fibers and polymers Vol.19 No.6

The controlling effect for dye exhaustion (adsorption) and diffusion (absorption) in a reactive dyeing of cotton is shown to be exerted by ionic strength in the dye solution rather than concentration of inorganic salts used as electrolytes. The study showed that the conclusion applies to both exhaust dyeing for dye exhaustion and pad dyeings for dye diffusion. Further, the addition of an alkali, even though it is not used as an electrolyte, increased the extent of exhaustion (in exhaust dyeing) and diffusion (in pad dyeing) due to increase in ionic strength of the dye solution. Hence, the total ionic strength of reactive dye solution for dye exhaustion and diffusion must be taken into account in order to ensure optimum reproducibility. Means for determining the total ionic strength of exhaust or pad dye solutions for different electrolytes are given.

Rajkishore Nayak,Amanpreet Singh,Rajiv Padhye,Lijing Wang 한국의류학회 2015 Fashion and Textiles Vol.2 No.1

In the field of textile and clothing, radio frequency identification (RFID), which is one of the most promising technological innovations, is used in manufacturing, inventory control, warehousing, distribution, logistics, automatic object tracking and supply chain management. Various retailers and manufacturers (of clothing as well as consumer goods) such as CVS, Tesco, Prada, Benetten, Wal-mart and Procter & Gamble, are now implementing the technology and exploring the impact of the technology on their business. RFID technologies may improve the potential benefits of supply chain management through reduction of inventory losses, increase of the efficiency and speed of processes and improvement of information accuracy. The basic of success lies in understanding the technology and other features to minimize the potential problems. Although the technology existed for several years, the technological challenges and cost issues are the major hurdles for the widespread use of RFID. In this paper, the authors have addressed the technology of RFID and various applications related to inventory management, production control, retail management, brand segregation etc. in textile and clothing industry. In addition, the disadvantages, challenges and future directions of RFID technology have also been highlighted.

Do Political Disruptions Affect Supply Chain Performance? A Qualitative Case Study of the Textile Supply Chain in Pakistan

Muhammad Asif,프렘 체트리,Rajiv Padhye 인하대학교 정석물류통상연구원 2019 JOURNAL OF INTERNATIONAL LOGISTICS AND TRADE Vol.17 No.3

This paper explores the interaction and impact of political disruptions on textile supply chain performance in Pakistan. A qualitative approach is adopted to explore the linkages and relationships between political disruptions and supply chain disruptions and performance. Semi-structured interviews were conducted at 25 different textile manufacturing firms. This study confirmed the prevalence of severe and variegated impacts of political disruptions on the textile supply chain. Supply chain disruption is found to be a key mediating factor that directly and indirectly affect supply chain performance through an increased production and delivery lead-time, transportation delays, interruptions of raw material supplies to plants and distributors and the restricted access to workplaces for suppliers and workers. The linkages are represented through vicious circles that illustrate the interactions and inter-relationships between disrupted supply chain and performance. This study provides empirical evidence to help government to formulate pertinent labour laws and industrial policy to mitigate political disruptions and minimise deleterious effects of supply chain disruption on production and distribution networks whilst respecting and protecting the democratic rights of people.

Impact Resistance and Comfort Properties of Textile Structures for Sportswear

Rajkishore Nayak,Sinnappoo Kanessalingam,Arun Vijayan,Lijing Wang,Rajive Padhye,Lyndon Arnold 한국섬유공학회 2020 Fibers and polymers Vol.21 No.9

Protective padding is commonly used in many sporting activities to prevent impact related injuries. In rugby,shoulder pads absorb and disperse the force and energy of an impact with a playing surface or another player. Although themajority of the commercial shoulder pads currently available can reduce the impact force during a front-on tackle, theyprovide limited amount of thermal comfort to the wearer. In this research, flexible textile structures were designed andinvestigated for their potential to effectively dissipate the force of impact over a wider area, thus reducing the risk of injury. The impact resistance of these textile structures placed over a body simulant was compared against commercial foam padsusing a ‘drop test’ method. The results indicated that all the flexible textile structures reduced the impact force. Although theirprotection level was not as high as the commercial foam, the textile structures showed a higher level of thermal comfort asmeasured by air permeability, thermal resistance and water vapor resistance. The results were analyzed using onewayANOVA followed by post-hoc analysis using IBM SPSS software. The Post-hoc analysis showed a significant differenceamong the test results of various fabrics for impact absorption, air permeability, thermal resistance and water vaporresistance, which are also discussed in this paper.
