活性染料S、E、F、R值测试与影响因素的研究

本文详细叙述了活性染料特征值(S、E、F、R)的测试方法,并系统研究了对特征值的影响因素,减小浴比,S、E、F、R值增大,S值对浴比变化不明显,提高染液中无机盐的浓度S、E、F、R增加,对S值高的染料则有所降低;碱剂用量则对S、E、P、R值的影响各不相同;温度升高S、E、F、R值有所下降,而R值有所提高。     

DRYING R D IN THE F.R. GERMANY

This paper summarizes the developments in the field of drying within the Federal Republic of Germany. The main areas on the scientific side (software) as well as those on the manufacturing'side (hardware) are discussed. This survey covers the period, 1976-1986.

On the theoretical side, research and development activities have focussed on convective and contact drying, modelling of contact dryers, selective drying of products with solvents, drying of mixtures and relevant topics in the field of ad-and desorption. On the hardware side, design to fit a changing framework (environment, energy, legislation, etc.), integration of up-and downstream equipment, detail improvements and new types of dryers (as well as applications of otherwise known equipment to drying) have been the major developments. A list of West German manufacturers of drying equipment is also in-cluded as an Appendix.

活性染料S、E、F、R值测试与配伍性能研究

本文采用活性染料特征值S，E，F，R（S-直接性值，E-吸尽值，F-固色值，R-固色速率）来评价染料的配伍性，选择双活性基型活性染料，按一定工艺处方，浸染纯棉织物，测定各染料S，E，F，R值，通过测试出的S，E，F，R值选择一些染料进行组合，拼色和研究，通过实验证明，用S，E，F，R值相近的染料拼色，染色时均匀上色。色相变化很小，而用S，E，F，R值相差大的染料拼色。染色过程中色差变化很大。染色难以控制。
