暂时性彩色染发液是利用高分子成膜物质的物理粘附作用,将彩色珠江颜粒有效地附着于头发表面而作为临时性装饰。选择粘附力强且柔软的聚乙烯醇吡咯烷酮为基料,加入25%的颜填料和适量的助剂,合成一种新型暂时性染发剂,并介绍了其制备工艺。该染发液具有色彩鲜艳,易洗使用方便等特点。 相似文献

根据颜色持续的时间长短,染发剂可以分为三类:暂时性染发剂,半永久性染剂,永久性染发剂。按照剂型染发剂可分为:乳膏型,凝胶型,染发香波,粉剂,染发摩丝等。现今市售染发产品种类繁多,其中主导位置的是以氧化染料为主要染色成分的永久性染发剂,尤其在我国市场上。本文重点探讨永久性染发产品。 相似文献

以氧化淀粉为例,建立氧化淀粉糊液泡沫的制备方法,并提出一种淀粉泡沫糊液粘附性能的测试方法,实现了淀粉糊液泡沫粘附性的客观表征。讨论了浆料配方、发泡剂浓度和烘燥方式对浆液粘附力的影响。结果表明,泡沫浆液对纤维须条的润湿、铺展和吸附是形成粘合的基础;内聚破坏和界面破坏是决定粘合破坏的关键因素;与单组分氧化淀粉相比,氧化淀粉和固体聚乙烯酰胺复配后糊液泡沫粘附力增加;发泡剂浓度在临界胶束浓度时,淀粉糊液泡沫的起泡能力、泡沫的稳定性和粘附力最好;相比于热风烘燥,真空冷冻干燥法可以有效提高淀粉糊液泡沫对纤维须条的粘附性。 相似文献

A series of water-soluble colored polyesters (polymeric dyes) were synthesized by interfacial polycondensation reaction of terephthaloyl chloride and various bisazodiols (monomeric dyes) that were derived from diarylidene cyclopentanone and diarylidene cyclohexanone by coupling with various diazonium salts of anthraquinone dyes containing the sodium salts of the sulfonic acid group. All the colored polyesters were characterized by their elemental analysis, IR and UV-visible spectroscopy, viscometry, solubility, and TGA. Color and dyeability of the polymeric dyes are discussed by comparing them with those of the corresponding monomeric dyes. The color fastness of the polymeric dyes show fair to very good fastness to light and very good to excellent fastness to washing, rubbing, perspiration, and sublimation. © 1998 John Wiley & Sons, Inc.

Production of colored kraft papers results in strongly colored paper machine spent Whitewaters (ww). The residual dyes prevent efficient recycle of the ww and necessitate periodic system cleanings. Many of the dyes are not adsorbed or degraded by biological effluent treatment and therefore discolor receiving waters. Ozone was tested as a bleaching agent for 15 direct paper dyes added at typical residual levels to kraft mill ww. These dyes included azo, polyazo, stilbene, benzothiazole and phthalocyanine direct dyes commonly used in Canadian dyed paper production. Ozone charges of 15 ‐100 mg/L rapidly bleached most of the dyes, although a few of the yellow stilbene and azo dyes were quite resistant. The efficiency of ozone‐mediated residual dye bleaching was altered substantially by the pH, the ww concentration, and the target dye's chemical structure. Preozonation of residual dye‐containing ww greatly decreased the color conferred to bleached kraft pulp fibers added to the ww. Thus, ozonation should permit much more ww recycle (less effluent) when changing colors on the paper machine. Depending on the availability of oxygen or ozone in a mill, and local ozone economics, ozone may be the most efficient, cost‐effective way to improve ww quality, increase ww recycle and minimize effluent color problems and environmental impact. 相似文献

The use high decomposition temperature fluorescent dyes to produce explosively disseminated colored smoke puffs has been demonstrated. The dye material used was a commercially available pigment that was a solid solution of an organic fluorescer in a polyamide resin. Practice shells were loaded with the fluorescent dye and the payload ejected with a black powder charge. Large, highly colored smoke clouds were produced by this method. The fluorescence spectra of the dyes and calculations of increased acquisition range due to the added fluorescence are presented. 相似文献
