  • Comfort and durability in high-Performance Clothing
    High-Performance Apparel, 2017
    Co-Authors: S. Motlogelwa
    Abstract:

    Abstract Clothing is a basic need for human beings that provides protection to the body from environmental and climatic hazards. Extreme conditions require properties that are application-specific rather than just a basic need. High Performance is a desirable attribute for professionals and comfort improves activity competence. A garment needs to be satisfactory for activity conditions for it to influence Performance. High-Performance textiles cover a wide range of textiles directed by the breath of activities depending on the end use. These include classes such as personal protective textiles, medical health protective textiles, and sportswear protective textiles. There are various tasks performed in adverse conditions such as firefighting, sports, and others. Executing these tasks in adverse conditions can reduce the ability to perform posing a threat to health and safety in the oversight of important considerations. The textile industry has focused on technical textiles with diverse properties that are able to satisfy the users' needs in different conditions. Technical textiles have high-technology characteristics and form an integral part of most protective Clothing. They are designed to protect the wearer from external and internal effects of the environment and climatic conditions. Protective textiles are essential to meet functional requirements of Clothing set in relevant regulations. There has been a transition from the use of natural fibers to using more synthetic fibers for high-Performance textiles. In this chapter, functional requirements for high-Performance Clothing were identified and discussed. Requirements for high-Performance apparel differ from everyday apparel and fabric design and garment design are utilized to achieve comfort for these products. Comfort, durability, sustainability, and future trends are also discussed in this chapter.

  • how is Performance in the heat affected by Clothing
    Journal of Fiber Bioengineering and Informatics, 2008
    Co-Authors: Ingvar Holmer
    Abstract:

    Adequate heat balance is critical to human Performance in the heat. If heat balance cannot be maintained, the core temperature increases and body water dehydration leads to exhaustion and limit the Performance. Clothing heat transfer properties.. thermal insulation and water vapour resistance, modify heat exchange and may indirectly affect Performance. Work in protective Clothing quickly becomes exhaustive in impermeable garments, but can be easily completed with much less strain in permeable garments. Athletes, in particular in sports of endurance type.. may produce more than 1000 W/m(2) in an event lasting several hours. Physical examination of the heat balance of a runner reveals that a 20% lower water vapour resistance of a covering running suit allows the runner a longer run time or a higher speed per kin before critical physiological strain is reached.

  • Effect of surface modification on the dynamic heat and mass transfer of wool fabrics
    Elsevier (United Kingdom), 2019
    Co-Authors: Li W, Zhao Y, Wang X
    Abstract:

    Surface functionalization of fibers is widely used to grant Performance or functions to textiles. Modified textile surface, with different morphology and wettability together with different thermal conductivity, has a profound effect on the wellbeing of wearer, because the thermal and moisture transfer of the surface-modified textiles in dynamic moving conditions is totally different to unmodified ones. To benefit the design of Performance/functional textiles with enhanced wellbeing of wearer, it is important to understand the dynamic thermal and mass transfer of textiles before and after surface modification. Using wool as a sample fiber, this work reveals the effect of typical surface modification on the dynamic thermal and moisture transfer of wool fabrics. It has been found that the surface characters of wool fiber change after surface modification with etched and peeled off scales, enhanced water absorbing capacity and wettability. The surface temperature of modified wool fabrics was lower than pristine wool fabrics when attaching to a rotating hotplate with a temperature of 35 °C, resulting in a lower energy consumption of the hotplate and enhanced warmth retention rate. Modified wool fabrics took longer time to accomplish the dynamic moisture transfer process with a longer stage three in the transfer cycle. This work will provide insights on how the surface of fiber affects the dynamic thermal and moisture transfer of textiles, which will further benefit the development of functional/Performance Clothing with its comfort well maintained
