Oyster shells are natural minerals from the ocean that can absorb body heat and release far-infrared rays, providing a warming effect. The recycled oyster shell yarn combines eco-friendly oyster shell powder sourced from the coastal areas of Changhua and Chiayi in Taiwan with advanced heat-insulating powder developed using innovative technology, creating an eco-friendly high-performance composite formula. Its functionality has been verified through various textile tests, showing natural heat insulation and antibacterial properties. This material has the potential for wide application in textiles such as underwear, sleeves, headbands, and T-shirts
Cheau Liang sources raw materials from the southwestern coast of Taiwan, specifically oyster shells collected from Changhua, Chiayi, and Tainan. These shells undergo sintering, grinding, and dispersion processes. After high-temperature calcination, the recycled oyster shells, obtained from agricultural, fishery, and livestock production, generate active oxygen and alkaline groups, offering excellent antibacterial and deodorizing properties. Cheau Liang is committed to creating innovative functional textiles that utilize ocean recycling, biochar, and natural marine minerals. These materials have promising applications in the market and are valuable resources for promoting environmental sustainability. The core of this innovation lies in using renewable resources, turning surplus materials into everyday products that not only reduce waste but also support the "green economy" for consumers.
The technology not only keeps Taiwan’s ocean-recycled resources local but also promotes the development of Taiwan's industrial chain and contributes to global net-zero emissions goals. The value of Taiwan's textile industry has grown from NT$52.3 billion in 2004 to over NT$360 billion in 2024, more than a sixfold increase, indicating a shift towards structural optimization and high-value applications. Cheau Liang not only utilizes recycled oyster shell resources but also applies graphene materials to produce medical-grade textiles with natural temperature-regulating and warming functions. Additionally, Cheau Liang has developed products applying the world’s first single-material moisture-responsive nylon fiber AquaBreath®, which demonstrates " absorbs moisture and elongates; condenses after drying " properties under varying humidity, providing cooling, quick-dry, and comfort features
