A Method for a Yarn-Spun Structure with Inherent Moisture Wicking and Fast-Drying Effects
Overview
Partnering with PolyU, HKRITA has developed an innovative yarn twisting technique and covering technology to modify the spun structure of yarn. This invention can improve both moisture wicking and transportation of yarn, preparing the yarn suitable for making sportswear.

Problem addressed
Sportswear require high drying rate and high moisture absorption simultaneously, but both existing synthetic and natural fibres are far from meeting such requirements. Chemical additives have to be added on synthetic fibres to achieve hydrophilic surface. Natural fibres such as cotton absorb moisture but they have poor water transportation.
Innovation
- By deploying physical-based coaxial and counter-rotating yarn wrapping technology to improve moisture management effects
- Reducing negative impacts caused by exposure to chemical pollutants with no extra chemicals
- Encouraging the use of natural fibres in a proportion greater than 80% and decreasing the utilisation of chemical-based synthetic or manmade fibres
Key impact
- To improve moisture wicking, fast-drying functionalities, good dimensional stability and strength without using chemical additives
- To overcome the drawbacks of both synthetic and natural fibres in terms of moisture management
- To give stock yarns a "second life" as this technology can be directly applied to the secondary upcycling of stock yarns
