Abstract: After being stretched, wool fiber would shrink under certain conditions. Based on this principle,the paper applies OPTIM wool into worsted fabrics. In the finishing stage, specific process parameters such as temperature, overfeed and time are set to maximize the shrinkage of the fabric and achieve a higher pick count. Without any chemical finishing aids, this method is green and environmentally friendly. And the finished fabric has good windproof and waterproof effects, which can be used in outdoor sports textiles,further expanding the application range of worsted wool fabrics.
