Note. Usually referred to as ordinary lyocell fiber or lyocell G100 fiber. 3.2 Lyocell A100 fiber lyocelA100 In the ordinary lyocell fiber production process, a cross-linking agent treatment process was added to obtain a lyocell fiber.4 PrincipleDissolving regenerated cellulose fibers other than lyocell A100 fibers from a mixture of known dry masses with formic acid/zinc chloride solution After removal, the remaining lyocell A100 fibers were collected, washed, dried and weighed to calculate the percentage of the dry mass of the mixture. Poor It is worth the quality fraction of lyocell G100 fiber, viscose fiber and bamboo pulp fiber. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of SN/T 4829-2017_English be delivered?Answer: Upon your order, we will start to translate SN/T 4829-2017_English as soon as possible, and keep you informed of the progress.
