Abstract


At home and abroad, the reverse micelle technology as an emerging technology, both in terms of the extraction separation of proteins, enzyme immobilization and Nanoparticles show the feasibility and superiority in biological engineering, medicine, food science and other fields to show its great potential for development and application value. In addition, in recent years the development of reverse micelle technology based on microemulsion technology, through the combination with other technologies the microemulsion fuel microemulsion washing, paint, cosmetics, fabric dyeing and finishing, leather processing and protection and many other areas shows the great potential for application. The alternative to the traditional reverse micelle system alkanes eco-friendly D5 (decamethyl cyclopentasiloxane siloxane) as a continuous phase medium successfully prepared the new D5 reverse micelle system and solubilization behavior of the system study were compared to the anionic surfactant, a cationic surfactant, non-ionic surface active agent of D5 reverse micelle system solubilizing water, neutral electrolyte, temperature, pH, aging time of D5 reverse micelles System Stability and saturated water solubilization and TX-10 / octanol / D5 reverse micelle system moisture and micelles of the relationship between the particle size, the system conductivity, and the results showed that: replaced with a non-polar of D5 alkane the traditional reverse micelles system to prepare a feasible method of eco-friendly reverse micelle system. The study reveals: the amount of alcohol cosurfactant and surfactant type and its concentration affect the amounts of water solubilized D5 reverse micelle system; TX-10 / octanol / D5 and 1831 / octanol / D5 anti water solubilization of the micellar system with neutral electrolyte added a sharp decline; highest stable temperature of the TX-10 / octanol / D5 system with the reverse micelle system water content increases overall downward trend, while the 1831 / octanol / the D5 system stability basic independent of temperature; TX-10 / octanol / D5 reverse micelle saturated solubilization of water are substantially independent of solubilizing water phase pH effect, while the 1831 / octyl alcohol / D5 reverse micelle saturated solubilization of water stable under acidic conditions, under alkaline conditions, decreases with increasing pH value; aging time on the TX-10 / octanol / D5 and 1831 / n a saturated water solubilization of the reverse micelles of the octanol / D5 is substantially no influence; TX-10 / octanol / D5 reverse micelle particle size, the viscosity becomes large with the W0 of the increase in its water content, and also the distribution of the particle size widens as W0 increase in the conductivity of the system, a mutation point mutation that free water began to appear in the system of reverse micelles. Dyeing of reactive dyes D5 reverse micelle system research system exploration, preferably suitable for reactive dyes for dyeing MOA-3 / octanol / D5 reverse micelle system, established reactive dyes D5 anti-plastic beam dyed cotton process routes and methods, and the of reverse micelles residue absorbance test and neutral electrolyte reverse micelle water content, fabric with a liquid rate of D5 reverse micelle reactive dyeing performance The results show that: the cellulose fibers swollen in advance in lye, and to carry a certain amount of lye into the dye staining method of the reverse micelle system is feasible, and a salt-free dyeing of reactive dyes can be successfully achieved; activity for composite active group the dye, prepreg rolling with lye containing 40g / L Na 2 the CO 3 , dyeing temperature 60 ° C, dyeing time 30min can get the best dyeing effect; neutral electrolyte MOA-3 / octanol / D5 reverse micelle reactive dye staining no significant acceleration effect; study also found that the pre-rolled lye fabric into the dye with the level of liquid rate of dye exhaustion rate big impact, with liquid rate is lower, the higher the rate of exhaustion of the dye, but no positive correlation between K / S value after exhaustion rate and the fabric fixing, the reason is for further study; D5 reverse micelles staining does not affect the fabric of the shade, have the potential to replace water as dyeing medium.
