摘要： Provided is a liquid crystal polyester fiber that suppresses gas generation during heating and has excellent hue. The liquid crystal polyester fiber has a total amount of carboxy end groups (total CEG amount) of 5.0 mEq/kg or less and a ketone bond amount of 0.05 mol% or less. For example, the liquid crystal polyester fiber may have a melting point of 380°C or lower. In addition, the liquid crystal polyester fiber may have a tenacity of lower than 18 cN/dtex. Moreover, the liquid crystal polyester fiber may contain a liquid crystal polyester having a structural unit derived from 4-hydroxybenzoic acid at a proportion of 50 mol% or more.

摘要： Provided is a creping adhesive that is favorable in a thread-forming property, wet adhesiveness, and the like. A creping adhesive contains a PVA (A), wherein at least one of (i) and (ii) below is satisfied. (i) The PVA (A) includes a PVA having a minimum degree of branching of 0.25 or more and 0.93 or less within a range of an absolute molecular weight being 200,000 or more and 800,000 or less, and a ratio Mw/Mn of a weight-average molecular weight Mw to a number-average molecular weight Mn of the PVA (A) is 2.5 or more. (ii) The ratio Mw/Mn of the weight-average molecular weight Mw to the number-average molecular weight Mn of the PVA (A) is 3.8 or more.
