On its journey to becoming a leading testing equipment manufacturer for textiles and nonwovens, as early as 1899 there are records of the delivery of the first twist tester by James Heal to a local mill.
Fast forward to 2022 and James H. Heal & Co. Ltd., Halifax/UK, continues to expand its range, with a focus on making testing simple, fast and intuitive – most notably with the introduction of its Performance Testing collection of instruments, most recently the AirPro and HydroView systems.
The way clothing interacts with the body, particularly in respect of the dissipation of heat and moisture, plays a major role in the wearer’s perceived comfort. Today, textile fabrics used for clothing have new functional properties to improve the wearer’s sensory and thermal comfort, meaning that air and water vapor permeability is crucial to achieving clothing comfort – particularly for performance apparel such as sportswear and outdoor clothing.
The new AirPro air permeability tester is used to test the resistance of the flow of air through woven, knitted and nonwoven textiles. Its software offers flexibility with standards and comprehensive reporting options and different test head sizes are available, making it suitable for a range of applications and standards.
The HydroView hydrostatic head tester is meanwhile designed to measure the penetration of water in materials which have an end use that requires water resistance, such as those in the medical, geotextiles and nonwovens sectors. It is also proving essential in the testing of end-use applications for technical textiles, such as in protective gloves, diving dry suits and winter sports apparel, to fishing waders, roofing, tenting, ground sheets and more.
