摘要
The industry uses color masterbatch mixing process and spinning for dope dyeing. There are color mending and color passivation appearance problems, and the process is inapplicable to functional apparel textiles. In this study, dyeable modified polypropylene (PP) fabric with disperse dye will be developed. The modified polyester material and PP for compounding processing with a compatibilizer will be used to make chips and the quality engineering method will be applied to analyze the optimum spinning process parameters. The fabric will be used to validate the dye washing fastness and light fastness in order to implement the dyeability of PP modified disperse dye. The optimum processing parameters to develop dyeable PP fiber will be studied. The modified materials are made into fiber by melt spinning, and the fuzzy C means technique is combined with the stem cells algorithm to design and analyze the processing parameters for the quality characteristics of tensile strength and elongation. The optimum fully drawn yarn is made. The tensile strength of the fiber of optimum parameter design is 3.66g/d, higher than the 3.36g/d of the pure PP fiber; the elongation is 38.65%, higher than the 36.66% of pure PP fiber, meaning the optimization method could improve the characteristics in melt spinning process, and conform with the standards of the textile industry. The fiber derived from the optimum parameters is woven into fabric for the disperse dyeing test and the validation of washing fastness shows the washing fastness is Level 3-4, meaning that the developed modified PP fabric has good dye-uptake and fastness.
