The rheology of the cellulose type spinning solution and the manner which improves process throughput

摘要

(57) Abstract This invention formula (i) below and/or arukokishirato which possesses (ii), regards adding the rheology of the cellulose type spinning solution and in order to improve process throughput. In X (NXR) _nNX2(i) type, as for X (as for B 24 alkyleneoxy where has carbon atom it is basis, at the same time, as for m it is the 17,) it is the hydrogen atom, the R₁ CO basis (as for R₁ 723 hydrocarbon group where has carbon atom) or the (B) _mH basis, the number of R₁ CO bases is 1 or 2, at the same time, the total number of B is the 220, R is the alkylene basis where the 23 has the carbon atom, at the same time, n the 210 to be desirable is the 37.
