Black fibers can be produced by
masterbatch or carbon black slurry injection into
polymerization process. The slurry injection into
polymerization process has the advantage of lower
cost and less breaks in spinning.
In slurry injection, the slurry
quality is critical, because carbon black is very
difficult to disperse in glycol. Good quality slurry
should have at least 500 ml in vacuum filtration through
57 mm screen of 325x2300 mesh.
Glysil Chemicals Inc. provides
complete technology package including black slurry
recipe, equipment specification, procedures, and
polymerization technology. Spinning of black fibers is
similar to regular polyester fibers.
Polyester Technologies Co. Ltd. produces high quality
carbon black slurry
Glysil®GS-36 in Wuxi, China.
Customers can add
Glysil®GS-36 into polymerization
process to produce black chip or black fibers.
