OPTIM™ spinning technology

Chemical-free water-resistant wool technology

Optim™ fibre stretching technology, co-developed by Nanshan and The Woolmark Company, pre-stretches Merino wool fibres which are then spun into yarn before being woven to create wind and water-resistant fabric made from 100% Merino wool. Optim™ technology enhances the wool fibre’s natural water repellent properties through a tight weave, offering water resistance and wind protection for outdoor performance wear without chemicals treatments or PFAS.

원리

옵팀 방적 기술

옵팀 섬유 스트레칭 기술은 메리노 울 섬유를 사용해 원사로 방적한 다음 100% 메리노 울로 만든 방풍과 방수성을 지닌 원단으로 직조합니다.

그 결과로 만들어진 메리노 울 원단은 옵팀가공이라는 공정 중에 늘어나지만 고정되지 않은 고급 메리노 울 원사를 사용하여 굉장히 높은 실 밀도의 날실과 씨실로 구성됩니다. 원단이 습식으로 가공된 경우에만 신축성이 풀리면서 원사가 수축되고 그로 인해 원단 구조가 극도로 조여지면서 엄청나게 조밀한 원단이 만들어집니다.

After optimising the spinning, weaving and finishing processes, the fabrics made from these stretched Merino wool fibres have enhanced water and wind resistant properties, while retaining all Merino wool’s fine properties such as breathability. These properties are achieved without any Durable Water Repellent chemical treatments like PFAS or “forever chemicals”. The fabric is also machine washable.

With France set to ban PFAS in clothing by 2026, Optim™ technology offers the perfect PFAS-free, water-resistant natural wool solution. No DWR treatments, no harmful "forever chemicals" - just pure Merino wool innovation, engineered for wind and water resistance.

Woolmark’s technical innovation team has continued to work with the Nanshan R&D team on the development of the Optim™ fabric, which is now commercially available in six different weights and options. The differing weights and the inherent properties of the wool fibre allow for interest from both the activewear, streetwear and smart-casual sectors of the global apparel industry.
