纤维素纤维、纤维素纤维的制造方法
摘要：
一种纤维素纤维、纤维素纤维的制造方法，纤维素纤维是下式(1)所示的纤维素的羟基由下式(2)所示的硼酸酯基取代，纤维素纤维包含如下至少一种结构物：第一种结构物，纤维素的同一纤维素分子链n的单位结构a、b之中的任一方的羟基由硼酸酯基取代；第二种结构物，纤维素的同一纤维素分子链n的单位结构a、b的双方的羟基由硼酸酯基取代；以及第三种结构物，纤维素的不同纤维素分子链n的羟基由硼酸酯基取代，由硼酸酯基取代的羟基所键合的碳是从单位结构a、b之中2位、3位、6位碳之中选择的两个碳，【化学式1】【化学式2】
摘要（英）：

A method for producing a cellulose fiber or a cellulose fiber, wherein the cellulose fiber is substituted by a boronic acid ester group represented by the following formula (2), and the cellulose fiber comprises at least the following A structure: a first structure in which one of the unit structures a, b of the same cellulose molecular chain n of cellulose is substituted with a boronic acid estergroup; the second structure, the same cellulose The hydroxyl groups of both the unit structures a and b of the cellulose molecular chain n are substituted by a boronic acid ester group; and the thirdstructure, the hydroxyl group of different cellulose molecular chains of cellulose is replaced by a boronic acid ester group, and boric acid The carbon to which the ester-substituted hydroxyl group is bonded is two carbons selected from the two, three, and six carbons of the unit structures a and b. Chemical formula 1 and chemical formula 2 are described in the specifications.
