How can you achieve water-repellent seams, reduce water ingress and prevent seam wicking?
Why do supposedly water-repellent, water-resistant or weather-protective textile products still allow moisture to penetrate through the seams?
Even when high-performance outer materials, waterproof laminates or fabrics with a durable water repellent (DWR) finish are used, the seam often remains the weakest point of a textile product. Water ingress, moisture ingress and seam leakage can occur through the needle holes and along the sewing thread due to capillary action, also known as the capillary effect, wicking effect, thread wicking or seam wicking. This unwanted moisture transport can significantly reduce the overall weather protection and functional performance of the finished product.
Our latest AMANN Knowledge Hub blog explains the key factors that influence seam water repellency and highlights practical measures to minimise water penetration. Learn how anti-wick sewing threads, anti-wick thread technology, water-repellent sewing threads, optimised sewing parameters, appropriate seam construction and correct thread selection help reduce the capillary effect, prevent water ingress and create more reliable, water-repellent seam constructions.
Whether you develop outdoor apparel, sportswear, functional clothing, workwear, protective clothing (PPE), footwear, luggage or other technical textiles, understanding the causes of moisture penetration is essential for achieving durable, high-performance seams and reliable weather protection.
Discover how anti-wick technology, water-repellent thread technology and proven sewing practices can improve seam performance, minimise moisture wicking, reduce thread wicking and deliver long-lasting protection against water ingress.
