摘要: IN WHICH R1 and R2 are each as defined above and p and q are each zero or a positive integer not more than 10, or blending the resultant polymer into linear fiber-forming polyesters.
Process for preparing polyesters improved in dyeability with acid dyes which comprises polycondensing a dicarboxylic acid with a glycol, the whole or part of the glycol being the one represented by the formula:
WHEREIN R1 and R2 are each a lower alkyl group or, when taken together, they represent a lower alkylene group, R3 is a lower alkyl group or a group of the formula:
D R A W I N G-

摘要: SYNTHETIC FIBERS-ESPECIALLY POLYESTER FIBERS, ARE DYED BY MEANS OF A REACTION PRODUCT OF A COMPOUND OF THE FORMULA
A-R-B-R''
AND A COMPOUND OF THE FORMULA
1-(Y=),4-(X-N=)-C
WHEREIN A IS AN AROMATIC NUCLEUS, B IS AN AROMATIC NUCLEUS OR A QUINOID RING, R IS -NH- OR -N=, R'' IS -OH OR =O, C IS A QUINOID RING, X IS A HALOGEN ATOM AND Y IS =O, =N-X,=N-OCCH3 OR
PHENYL-SO2-N=
THE DYED FIBERS, OF DARK SHADE, ARE OF EXCELLENT FASTNESS TO LIGHT, SUBLIMATION, WASHING AND DRY-CLEANING.
