【摘要】 探讨了不同脱胶工艺对菠萝叶纤维物理性能的影响。用浓烧碱对菠萝叶纤维溶胀改性,并用活性染料对棉纤维、苎麻纤维、改性的菠萝叶纤维和未改性菠萝叶纤维染色。结果表明,菠萝叶纤维对活性染料的染色性能介于棉纤维与苎麻纤维之间,改性后的菠萝叶纤维对染料的上染性和提升性显著提高,可用活性染料染中深色或深色。更多还原

【Abstract】 This article investigated the effect of different degumming processes on the physical properties of pineapple leaf fiber.Pineapple leaf finer was modified by concentrated NaOH solution.Cotton,ramie,modified and unmodified pineapple leaf fibers were dyed with reactive dyes respectively.The results of experiments showed that the dyeing behavior of the pineapple leaf fiber is between those of cotton and ramie.Modified pineapple leaf fiber has better adsorption and building-up on reactive dyes and can be dyed medium to deep shades with reactive dyes.更多还原
