Dye can bring a little color to life, most clothing is color with dyes, modern manufacture dyes can be costly, natural dyes from plan t and animal products have been used since ancient times, so this week, we describe by natural way to dye world, the advice comes from information written by Jenny Tim of the intermedial technology development group in Briton, this anti group is now called practical action, there are several messages to put dye onto material, the vent message for example, can be used to dye wool with onion skins, for this example, use 100 grams of natural wool, the wool must be clean, leave it overnight in water and liquid soap, then wash it with clean water that is a little warm, gently out the water, a solution called a moderant is used in the dying process, a moderant helps fix the dye to the material, traditionally moderants were found in nature, wood ash is one of example, but chemical moderants such as ironare popular today, iron is so would in many stores, it is often mixed with queen of daughter, a finding powder commonly used in cooking.
使用染料可以为生活带来更多的色彩。许多的布料都是通过染料来上色的。现代工业制造的染料通常都非常的贵,从古时起,人们就知道从植物或者动物产品中提取天然染料。这周,我们就来讨论一下如何用天然的方法来给羊毛着色。这一建议来自英国中级技术发展组的Jenny Dean的信息。这一古老贫穷的小组现在被称为实用性活动。把染料加到材料上有几种方法。其中之一是大桶法。举例来说,就是用洋葱皮来染羊毛。这一例子中,用100g的天然羊毛。羊毛必须清洗。用液体肥皂浸泡过夜。然后用温的干净的水冲洗它。轻柔地把多余的水分压挤出来。一种叫做媒染的溶剂也用于染洗过程。媒染是用来固定染料和材料的。传统的方法是,媒染是来天然的,比如木灰。但是像明矾这样的化学媒染在今天也是很流行的。明矾在许多商场都有出售。它通常和一种经常被用于烹调的粉状物-酒石混在一起。我们用多一点点的辛苦,来交换多一点点的幸福

Two series of polyurethane acrylate grafted acrylic resins (Acr-g-TPU-PETA and Acr-gPPU-PETA) self-emulsifying systems are obtained by grafting -NCO group modified polyurethane acrylates with acrylic copolymer prepared from n-butyl acrylate, styrene,βhydroxyethyl methacrylate and acrylic acid The self-emulsifying systems showed Newtonian fluidity with viscosity closed to that of water, the solid contents were around 30% The T〓 of 15~4℃ for dried film before photocuring favored film formation at room temperature DSC and DMA results showed that PU-PETA is compatible with acrylic resin in the grafted resin The TG and dTG curves for Acr-g-PU-PETA samples were substantially different from the corresponding blends, and the brodened dTG peaks for photocured grafted resin suggest that there might be multiple interactions among chain segments The photocued film of the grafted resins self-emulsifying system exhibited good overall properties with polyurethane acrylate grafts ranging from 30% to 50%, and Acr-g-TPU-PETA series showed better properties than Acr-gPPU-PETA series The adhesion of the photocured film was 1~2 grade, impact strength was 50kg-cm and flexibility was 1mm The Shore hardness and the adhesion of the film decreased markedly if PETA was replaced by HEMA as photoactive group due to the lower C=C double bond content in the grafted resin The polyhydroxy amine-linked thioxanthones photoinitiators can be evenly dispersed in self-emulsifying system without color spot appearing in the dried film The films photocured with IV〓~IV〓 generally exhibited higher Shore hardness, gloss and solventresistance than that cured with Irgacure 2959 and did not induce the rusting of the iron substrate Pigmenting with titanium oxide had no effect on the photocuring The polyhydroxy amine-linked thioxanthone IV〓 and IV〓 can be new candidates for the formulation of titanium oxide pigmented photocurable water-borne coatings for their pale-yellow appearance and slight interference with the color of the coatings WB 4759 with high water-solubility coalesced and separated from the dried resin film, and even induced the rusting of iron substrate.
以丙烯酸丁酯,甲基丙烯酸-β-羟乙酯,丙烯酸及苯乙烯合成厂丙烯酸共聚树脂,并与含-NCO端基的聚氨酯丙烯酸酯接枝反应,经水性化后,得到两个系列(Acr-g-TPU-PETA和Acr-g-PPU-PETA)各5个不同配比的丙烯酸树脂接枝聚氨酯丙烯酸酯自乳化体系,粘度与水相近,为牛顿流体,固含量30%左右。光固化前干燥涂膜的玻璃化转变温度在-15℃~4℃之间,有利于室温下成膜。DSC及DMA谱表明两种树脂基本相容。Acr-g-PU-PETA的热失重行为明显不同于共混材料,接枝样dTG峰明显宽化,表明接枝样中链段之间的相互作刚有多重性,丙烯酸树脂与聚氨酯之间有一定的相容性。接枝树脂自乳化体系光固化涂层的综合性能以聚氨酯丙烯酸酯成分为50%~30%者相对较好,且以Acr-g-TPU-PETA系列更理想。光固化膜的附着力为1~2级,冲击强度为50kg·cm,柔软性多为1mm。以HEMA代替PETA作为接枝树脂的活性基团,碳—碳双键密度太低,光固化膜交联点太少,硬度和附着力均较差。多羟基胺连硫杂蒽酮光引发剂能均匀分散于树脂自乳化体系和接枝树脂干膜中,不出现色斑,光固化膜肖氏硬度一般高于以Irgacure 2959为光引发剂的光固化膜,光泽度及耐丁酮溶剂性能均有所提高,不会诱导铁基生锈,钛白着色对光固化结果几乎没有影响。本论文所合成的多羟基胺连硫杂蒽酮光引发剂IV〓与IV〓为浅黄色,对光固化涂层的颜色干扰较小,为配制钛白着色光固化水性涂料提供了新的光引发剂。水溶性太强的WB 4759在干膜中易聚结析出,且对所附着的铁基有诱导锈蚀作用。

A broad expanse of the river was turned to blood; in the middle distance the red hue brightened into gold;,through which a solitary log came floating ,black and conspicuous; in one place ,a long slanting mark lay sparkling upon the water; in another the surface was broken by boiling ,tumbling rings, that were as many-tinted as an opal; where the ruddy flush was faintest ,was a smooth spot that was covered with graceful circles and radiating lines, ever so delicatedly traced; the shore on our left was densely wooded ,and the somber shadow that fell from this forest was broken in one place by a long, ruffled trail that shone like silver; and high above the forest wall a clean-stemmed dead tree waved a single leafy bough that glowed like a flame in the unobstructed splendor that was flowing from the sun. there were graceful curves ,reflected images ,woody heights ,soft distances ; and over the whole scene ,far and near ,the dissolving lights drifted steadily ,enriching it every passing moment with new marvels of coloring.
还记得自己刚开始船上生涯时所见过的那次辉煌的落日:宽阔的河面一片血红;不远处这红色明亮起来,变成金色,一根显眼的黑色圆森木从中漂过;这边,一根长长的浮标倾斜在水面上,熠熠闪光;那边,翻滚的波浪打破了宁静的水面,像猫眼石般色彩纷呈;微红的水流最缓和处,美丽的涟漪在平稳的水面上层层荡漾开去;左侧的河岸上丛林茂密;一条如银带般闪亮的小径从昏暗的树荫中蜿蜒而出,伸向远处;高高的密林之上有一根无枝无蔓的枯树,仅留有一根带叶的树枝在风中晃动,在太阳一泻千里的光辉里,它宛如燃烧的一团火;还有优美的波纹、水中的倒影、树木葱茏的高地、柔和的远景;放眼望去,由远及近,逐渐裉去的光线随波荡漾,每时每记得都以其新的奇妙着色为这条河添姿增彩。
