我司棉織物低溫練漂技術(shù)研究論文發(fā)表于美國化學(xué)學(xué)會雜志

2014年5月28日,在美國化學(xué)學(xué)會(ACS)的雜志Industrial &Engineering Chemistry Research(IECR)即工業(yè)與工程化學(xué)研究雜志,發(fā)表了我公司有關(guān)低溫練漂的研究論文:《A Novel LowTemperature Approach for Simultaneous Scouring and Bleaching of Knitted CottonFabric at 60°C》(一種在60℃對棉針織物同時進行精練和漂白的新型低溫加工工藝),為此,ACS的新聞周刊還專門撰文介紹,題目為“A more earth friendlyway to make bright white cotton fabrics”(一種更加環(huán)保的棉織物漂白方法)。

Amore earth friendly way to make bright white cotton fabrics

"ANovel Low Temperature Approach for Simultaneous Scouring and Bleaching ofKnitted Cotton Fabric at 60°C"

Industrial& Engineering Chemistry Research

Witha growing number of consumers demanding more earth-friendly practices from thefashion world, scientists are developing new ways to produce textiles thatcould help meet rising expectations. They report in the ACS journal Industrial& Engineering Chemistry Research one such method that can dramaticallyreduce the amount of energy it takes to bleach cotton while improving thequality of the popular material.

QuanZu and colleagues point out that the cotton industry’s current whiteningtechniques require bleaching the natural fiber at very high temperatures withhydrogen peroxide. Although this method results in the bright white materialconsumers have grown so fond of, it also lowers the quality of the material andtakes a lot of energy to carry out. Multiply that by the 7.3 billion pounds ofcotton produced in the U.S. alone, and the energy needs soar. To cut down onthe energy the textile industry uses to make cotton, Zu’s team targeted itsefforts toward lowering the bleaching technique’s high temperatures.

Theydeveloped a novel compound that, when used with hydrogen peroxide, drops the bleachingtemperature down to 140 degrees Fahrenheit from 200 degrees. The authorsestimated that 60 degree difference would result in a process requiring lessthan half the energy as the commercial technique. It also produced lesswastewater, improved the weight of the material and performed its originalfunction — whitening the cotton. Since many materials destined to becomeclothing eventually take on various hues, the scientists also tested dyes andfound the cotton bleached at the lower temperature could be made just asvibrant as its high-heat counterpart. They successfully showed the treatment’seffectiveness on knitted cotton fabric in commercial scale trials.

一種更加環(huán)保的棉織物漂白方法

“一種在60℃對棉針織物同時進行精練和漂白的新型低溫加工工藝”工業(yè)與工程化學(xué)研究

隨著越來越多的消費者要求在世界上實施更環(huán)保的生產(chǎn)方式,科學(xué)家們正在開發(fā)新的方法來生產(chǎn)紡織品,可以幫助滿足這種不斷提高的期望?,F(xiàn)在ACS的工業(yè)與工程化學(xué)研究期刊上刊登了一個這樣的方法,可以大大減少漂白棉織物所花費的能源,同時還能提高這種廣泛應(yīng)用材料的質(zhì)量。

朱泉教授和他的同事們指出,目前工業(yè)上棉花漂白技術(shù)是在很高的溫度下使用過氧化氫來漂白的。雖然這種方法生產(chǎn)的精白棉織物很受消費者青睞,但它降低了材料的質(zhì)量并耗費了大量的能源。僅在美國生產(chǎn)的棉就有73億磅(331萬噸),能耗極其巨大。為在紡織生產(chǎn)中減少棉加工的能耗,朱教授的研究團隊以降低漂白溫度為目標(biāo)做了深入研究。

他們開發(fā)出一種新型化合物,與過氧化氫使用時,可使棉的漂白溫度從華氏200度(95℃)下降到140度(60℃)。作者估計這60度(華氏)的差異可使生產(chǎn)過程需要的能量減少一半以上。這一技術(shù)在漂白棉花的同時,還能減少廢水排放,增加加工后棉的重量。因為用做服裝的許多材料需要染色,這些研究者還測試染色性能,并發(fā)現(xiàn)在較低的溫度下漂白的棉織物其各種性能與相應(yīng)的高溫漂白的棉織物相當(dāng)。他們也成功地在工業(yè)生產(chǎn)設(shè)備上對棉針織物進行了練漂試驗,證明了此法的有效性。
