为了开发低温丝光的耐用仿亚麻棉纱，研究了确保低温碱溶液高效、均匀渗透到棉纱中的预处理方法。评估由较高 NaOH 浓度的碱洗和纤维素酶处理以及随后的碱洗组成的预处理在去除蜡和增强吸收性能方面的效率。在较高 NaOH 浓度下，纤维素酶处理/碱洗比碱洗更能有效地去除蜡。经过纤维素酶处理和随后的碱洗，蜡含量低于 0.1%。纤维素酶处理似乎可以降解棉纤维表面的纤维素，使其更容易接触到精练剂，并使蜡更容易去除。通过比较溶胀时间和润湿时间来确定足以开发亚麻状棉花的预处理。在低温丝光处理中，通过纤维素酶处理和碱洗组成的预处理可产生类似亚麻的棉纱，其挺度可耐受针织、湿加工甚至十次洗涤循环。耐用性似乎足以满足生产类似亚麻棉的工艺的实际应用。
In order to develop durable linen-like cotton yam with low temperature mercerization, pretreatment methods ensuring efficient and uniform penetration of the low temperature alkali solution into cotton yarn are studied. Pretreatments consisting of an alkaline scouring at higher NaOH concentrations and of a cellulase treatment and subsequent alkaline scouring are evaluated for their efficiency in removing wax and enhancing absorptive properties. The cellulase treatment/alkaline scouring is more efficient at re moving wax than alkaline scouring at higher NaOH concentrations. The cellulase treat ment and subsequent alkaline scouring result in wax contents lower than 0.1%. The cellulase treatment appears to degrade the cellulose on the surface of the cotton fibers, making it more accessible to the scouring agent and making wax removal easier. Swelling and wetting times are compared to identify a pretreatment sufficient for developing linen-like cotton. In low temperature mercerization, the pretreatment consisting of cellu lase treatment and alkaline scouring yields a linen-like cotton yarn whose stiffness is durable to knitting, wet processing, and even ten laundering cycles. The durability appears to be sufficient for practical applications of the process for producing linen-like cotton.
