From the Sector

The Paris 2024 Summer Olympic Games are just around the corner and a global sports frenzy is underway. However, intense summer workouts often lead to sportswear absorbing excessive sweat, becoming clingy and cumbersome, causing discomfort and potentially impacting performance. A research team from the School of Fashion and Textiles at The Hong Kong Polytechnic University (PolyU) has developed the iActive™ sportswear range which features a root-like liquid transport system and a skin-like active perspiration dissipater and utilises nature-inspired, anti-heat textile fabrics to expedite sweat removal, effectively reducing the weight and stickiness of activewear caused by sweat accumulation during exercise.

The human body has millions of sweat glands that are vital for regulating body temperature by dissipating sweat for evaporation to cool the skin’s surface. With unabating greenhouse gas emissions, the number of very hot days annually is expected to increase significantly. This will lead to elevated energy consumption and increased sweating during physical activity and outdoor labour. Even when wearing highly breathable clothes with good sweat-wicking properties, individuals may still experience discomfort due to excessive sweat accumulation.

A research team led by Dr SHOU Dahua, Limin Endowed Young Scholar in Advanced Textiles Technologies and Associate Professor of the School of Fashion and Textiles at PolyU, has invented the iActive™, intelligent, electrically activated sportswear with a nature-inspired active perspiration function.

Its nature-inspired technologies, including low-voltage-driven artificial “sweat glands” created by skin-like anti-heat textile fabrics and a root-like branching liquid transport system that aligns with the body’s sweat map, can actively and programmably remove sweat to a perspiration dissipater at the lower region of the sportswear. The all-textile sweat dissipater is compact and operates at a safe output voltage of approximately 5-9V, and its battery is easy to detach from the clothing, making it convenient for users to repeatedly wash the clothing by hand or in a washing machine to maintain hygiene. When the human body’s sweat rate is low, iActive™ can still be used independently without the battery.

Based on the optimised wettability pattern and gradient, the research team utilises a skin-like textile fabric to transport sweat one-way quickly and dissipate it from the inside to the outside. This feature reduces the stickiness and weight of clothing, improves breathability and ensures the garments remain dry and comfortable to wear. Experimental findings indicate that iActive™ creates a breathable and dry skin microclimate by dissipating sweat at a rate that is three times faster than the maximum human sweating rate. This innovation can also prevent discomfort from coldness and moisture after a workout. In comparison to traditional fabrics, the textile materials in iActive™ are 60% lighter and 50% less clingy when soaked, providing the wearer with all-round comfort and enabling sports enthusiasts and athletes to perform at their best.

Furthermore, a mobile app further aids personalised sweat management by wirelessly adjusting the sweat level of iActive™. This innovation is versatile and can be seamlessly integrated into a variety of textile materials to facilitate sustainable mass production. Beyond sportswear, iActive™ is also well-suited to protective clothing and workwear for individuals engaged in prolonged, high-intensity physical labour and outdoor occupations, including healthcare professionals, construction workers, firefighters, law enforcement officers and others, thereby significantly enhancing their work performance.

Dr Shou Dahua stated, “The extreme weather and high temperatures resulting from global warming have elevated the importance of heatstroke prevention and cooling measures on a global scale. Drawing on the vivid phenomena of thermal insulation and directed liquid flow in nature, we aim to foster innovation and sustainable advancement in garment manufacturing by inventing intelligent clothing and materials to address global challenges. We seek to harness the power of technology to infuse fresh perspectives into the traditional clothing industry, thereby enhancing its competitiveness.”

His research team has also developed a premium fabric named Omni-Cool-Dry™, drawing inspiration from volcano dwelling beetles. This fabric not only provides ultra-fast sweat dissipation and ensures all-day comfort with its dry and breathable features under dynamic thermal conditions, but also reflects solar radiation and emits body heat into the cold universe, enabling passive cooling. The team is working hard to leverage the benefits of both inventions to further enhance the sweat-dissipating and cooling capability of iActive™ sportswear.

Dr Shou Dahua, a core member of the PolyU Research Institute for Intelligent Wearable Systems and the Research Centre of Textiles for Future Fashion, has recently been bestowed with the 2023 Distinguished Achievement Award by The Fiber Society for his outstanding contributions to the fields of personal thermal and moisture management, intelligent wearables and soft robotics. The accolade is presented annually to an individual researcher worldwide. He has also received international innovation awards, including consecutive TechConnect Global Innovation Awards in 2021 and 2022. Moreover, his research papers have been published in various internationally renowned academic journals including Science Advances, PNAS, Advanced Functional Materials, and Advanced Energy Materials. Dr Shou will be chairing The Fiber Society Spring 2025 Conference at PolyU.

• Producing fabric for medical gowns: Advanced barrier effect solutions support COVID-19 efforts

Huntsman Textile Effects and Bao Minh Textile, one of the largest and most modern woven fabric producers in Vietnam, are collaborating to produce fabric that meets the stringent performance standards required of isolation gowns. High-quality medical gowns are essential protective wear for healthcare workers combatting the global COVID-19 pandemic, but these are in short supply worldwide.

Bao Minh Textile will initially treat 760,000 meters of woven fabric with a carefully curated combination of Huntsman Textile Effects barrier effect solutions and auxiliaries. This fabric is sufficient to produce 345,000 high-grade isolation gowns.

Bao Minh Textile’s isolation gown fabric relies on a range of Huntsman pretreatment, dyeing and finishing solutions. These include CLARITE® ONE, an all-in-one pretreatment for peroxide bleaching; NOVACRON® and TERASIL® dyes; PHOBOL® CP-C, an excellent oil-, water- and stain-repellent finish; and PHOBOTEX® RSY, a non-fluorinated durable water repellent with extremely high washing resistance. PHOBOL® EXTENDER XAN is also applied to further increase wash durability.

California Linen Services of Pasadena, Calif. has been recertified Clean Green, reflecting the company’s dedication to standards for operational efficiency and sustainability. The certification quantifies linen, uniform and facility services’ environmentally friendly performance by confirming an operation launders within TRSA-designated water and energy use thresholds; and verifies use of best management practices (BMPs) in line with the ASTM International environmental laundering standard.
 
California Linen Service’s customers can be assured their reusable healthcare textiles are washed, dried and finished with processes that maximize sustainability and reduce greenhouse emissions. Clean Green certified operations demonstrate significant commitment to conservation and green operations through these BMPs:

• Recovering heat from drained hot water and heat dispersed from the process of warming water
• Recapturing drained water from rinses for reuse
• Using environmentally friendly detergents
• Removing solids and liquids from wastewater
• Solar energy and energy-efficient lighting
• Recycling programs
• Re-routing trucks to save vehicle fuel
• Spill prevention plans

California Linen Service earned the Clean Green certification initially in 2015. The designation is valid for three years at a time. TRSA inspects laundry facilities seeking certification and approves documentation of their water and energy use and BMP deployment through production reports they submit to auditors during the inspections. TRSA’s certification management protocol includes auditor training by the association’s inspection program administrator.
Clean Green aligns with the ASTM International standard, Guide for Sustainable Laundry Practices, which recognizes key criteria for the certification as universal indicators of maximum sustainability in commercial laundry work. ASTM’s review of TRSA BMPs verified these as the most effective and practical techniques for a laundry to achieve green objectives.
TRSA members prompted development of the standard, which was vetted in the sustainability subcommittee of the ASTM Committee on Textiles. Top technical experts, scientists and environmental professionals from outside the linen, uniform and facility services industry reviewed the BMPs. ASTM is the global leader in developing and delivering voluntary consensus standards unparalleled in building consumer confidence in product and service quality.
 
“I applaud California Linen Services for their ongoing sustainability efforts and maintaining the highest standards in their production and delivery operations,” said Joseph Ricci, TRSA president and CEO. “Meeting all the criteria for certification is not easy, but the company is committed to industry-leading processes and technologies.”

• Emphasis on Process, Third-party Validation and Outcome-based Testing

ALEXANDRIA, Va., February 16, 2018 —Kansas City, Mo.-based Superior Linen Supply has again achieved Hygienically Clean Healthcare certification, reflecting their commitment to best management practices (BMPs) in laundering as verified by on-site inspection and their capability to produce hygienically clean textiles as quantified by ongoing microbial testing.

The laundry was first certified in 2014. Recertification confirms the organization’s continuing dedication to infection prevention, compliance with recognized industry standards and processing healthcare textiles using BMPs as described in its quality assurance documentation, a focal point for Hygienically Clean inspectors’ evaluation. The independent, third-party inspection must also confirm essential evidence that:

• Employees are properly trained and protected
• Managers understand regulatory requirements
• OSHA-compliant
• Physical plant operates effectively

To achieve certification initially, laundries pass three rounds of outcome-based microbial testing, indicating that their processes are producing Hygienically Clean Healthcare textiles and diminished presence of yeast, mold and harmful bacteria. They also must pass a facility inspection. To maintain their certification, they must pass quarterly testing to ensure that as laundry conditions change, such as water quality, textile fabric composition and wash chemistry, laundered product quality is consistently maintained. Re-inspection occurs every two to three years.

This process eliminates subjectivity by focusing on outcomes and results that verify textiles cleaned in these facilities meet appropriate hygienically clean standards and BMPs for hospitals, surgery centers, medical offices, nursing homes and other medical facilities.

Hygienically Clean Healthcare certification acknowledges laundries’ effectiveness in protecting healthcare operations by verifying quality control procedures in linen, uniform and facility services operations related to the handling of textiles containing blood and other potentially infectious materials.

Certified laundries use processes, chemicals and BMPs acknowledged by the federal Centers for Disease Control and Prevention (CDC), Centers for Medicare and Medicaid Services, Association for the Advancement of Medical Instrumentation, American National Standards Institute and others. Introduced in 2012, Hygienically Clean Healthcare brought to North America the international cleanliness standards for healthcare linens and garments used worldwide by the Certification Association for Professional Textile Services and the European Committee for Standardization.

Objective experts in epidemiology, infection control, nursing and other healthcare professions work with Hygienically Clean launderers to ensure the certification continues to enforce the highest standards for producing clean healthcare textiles.

“Congratulations to Superior Linen Supply on their recertification,” said Joseph Ricci, TRSA president and CEO. “This achievement proves their ongoing commitment to infection prevention and that their laundry takes every step possible to prevent human illness.”
