双雨露汉麻超柔面料染整工艺的创新研究OA

Although hemp fibers possess inherent advantages such as exceptional antibacterial properties,moisture absorption,and breathability,their application in high-end textiles has been limited by issues like coarse hand feel,poor spinnability,and batch difference control in production.This study focuses on double-retted hemp blended products and systematically analyzes the microstructural differences among hemp,flax,and ramie fibers.A refined dyeing and finishing process integrating"singeing→mercerizing→oxygen bleaching→stentering →pre-shrinking→mechanical softening"was de-signed.By accurately controlling the parameters of each process,the fiber properties are effectively stabilized and batch dif-ferences are reduced.The core innovation lies in the compound technology of polyurethane-based softeners and hydrophilic softeners,successfully resolving the challenge of balancing hand feel and moisture absorption in hemp products.The re-sults show that the double-retted hemp ultra-soft fabric produced via this process not only fully retains the inherent dura-ble antibacterial properties of hemp,but also achieves moisture absorption:the drip diffusion time is less than 1 s,far ex-ceeding the standard requirements;moisture dispersibility:efficient moisture management with a moisture permeability greater than 12 000 g/(m2·24 h)and an evaporation rate greater than 0.30 g/h,endowing the fabric with a unique silky soft and smooth touch.
