In order to reduce or prevent fibre brittleness, the following points should be paid attention to after dyeing with sulphur black br dye:

» The amount of sulphur black dyes should be limited, and the amount of mercerized primary dyes should not exceed 700 g/bag. Because the amount of dye is high, the chance of brittleness is great, and the fastness of dyeing is reduced, so it is difficult to wash.

» After dyeing, it is necessary to wash the yarn thoroughly to prevent it from being unclean. The float color of the yarn is easy to decompose into sulfuric acid during storage and make the fibers brittle.

» After dyeing, it must be treated with urea, soda ash and sodium acetate to prevent brittleness.

» The dyed yarn should be dried in time, because the wet yarn is easy to heat in the stacking process, which reduces the content of anti-brittleness agent and the pH value of the yarn, which is not conducive to anti-brittleness.
