Study on the scouring-bleaching technology of Xinjiang scutched flax

Abstract

This study explored and improved the optimal scouring-bleaching process of Xinjiang scutched flax, based on its characteristics and the scouring-bleaching process of existing mature flax. The physical properties, such as length, strength, split degree and fineness, and the chemical composition of Xinjiang scutched flax, such as the content of cellulose, lipowax, pectin, hemicellulose, water-soluble matter, lignin, etc., were measured and analyzed. The approximate range of bleaching process parameters was determined referring to the existing general flax scouring-bleaching process. Thirdly, the orthogonal experiment of three factors and three levels interaction is designed, and the optimal scouring-bleaching process scheme is obtained after analysis and verification.
