新型荧光增白剂CBW-01在洗衣粉中的应用研究

将新型荧光增白剂CBW-01配入洗衣粉中,并与常用的荧光增白剂作对比,通过粉体白度实验、去污实验、织物白度实验和稳定性实验,考察了CBW-01的性能。结果表明,CBW-01在洗衣粉中添加的质量分数为0.02%时,使粉体白度提高了20.45%;添加的质量分数为0.2%时,使去污力比值提高至1.30;添加的质量分数为0.1%时,循环洗涤20次后,对白棉布和白混纺布的白度保持率分别为112.38%和108.25%。在光照16 h和105℃加热48 h后,CBW-01在洗衣粉中的白度衰减率分别为15.36%和1.93%。CBW-01是一种性能优良的洗衣粉用荧光增白剂。     

洗衣粉去污力实验室评价方法的改进

按衣料用洗涤剂国家标准(GB/T 13174-2003)中去污力测定方法对3种标准污布进行了去污试验,发现标准规定的洗涤质量浓度0.2 g/L存在不足;在标粉质量浓度0.1 g/L~0.4 g/L下洗涤,其去污试验数据显示,洗涤差值随洗涤质量浓度的增加而增大,经精密度分析确定了洗涤质量浓度为0.3 g/L的试验洗涤浓度。通过对洗衣粉质量浓度为0.3 g/L洗涤实际去污力的测定,结果表明:质量浓度0.3 g/L下洗涤,洗衣粉在3块标准污布上洗涤结果的重复性和精密度均好于GB/T 13174-2003所规定的0.2 g/L。     

抗再沉积剂在洗衣液中的应用研究

分别选用了聚丙烯酸钠、改性聚乙二醇、苯乙烯-丙烯酸共聚物和改性聚乙烯亚胺配入洗衣液中,考察其在洗衣液中的抗再沉积性能。通过去污实验和循环洗涤实验,测定了污布和白布在洗涤前后的光谱反射率。去污实验表明,抗再沉积剂的加入可明显提高洗衣液对皮脂污布的去污力。循环洗涤实验表明,加入抗再沉积剂均可以提高洗衣液对棉布的白度保持,而当采用2种抗再沉积剂复配使用时,抗再沉积效果较好,对棉布的白度保持比对照样品提高3%～12%。

Detailed analysis of the UV‐adjustment techniques used in paper and graphic industries

Many commercial materials (papers and boards) contain optical brightening agents also known as fluorescent whitening agents. Adequate adjustment of the UV content of a measurement device (e.g., spectrophotometers) is essential for accurate color measurement. As specified in the ISO standards, the UV content is adjusted against an assigned value of an international reference transfer standard, for example, CIE whiteness (D₆₅/10°) for the CIE illuminant D₆₅ or ISO brightness for the C illuminant. Because of the simplicity, these approaches have gained great popularity in papermaking industry. Yet, there has been little evidence indicating how accurate the total spectral radiance factor corresponding to the single assigned value is reproduced. Hence, we present a method that quantitatively evaluates the accuracy of the UV‐adjustment technique, through comparing the total spectral radiance factors obtained from UV adjustment with the assigned ones. This method has been applied to three second‐level international reference transfer standard illuminated by three standard illuminants, D₆₅, C, and D₅₀. We found that the major differences between the assigned spectra and those obtained from the UV adjustments occur in the blue band where fluorescence is strong. At a few wavelengths, the differences may be up to 4–5%. Nevertheless, their color differences corresponding to the assigned spectra and those obtained from the UV adjustments are still smaller than unity (1 ΔE*) for all of the illumination conditions. Two instruments using the representative UV adjusting techniques, for example, the conventional UV‐adjusting with an adjustable (GG395) UV filter and the numerical UV‐filtering, have been studied. © 2016 Wiley Periodicals, Inc.

Solid nonionic surface-active agents

Summary Methods have been described for converting liquid nonionic surface-active agents of the polyoxyethylene type to solid compositions by complexing with urea. It is shown how these solid products may be made in the form of free-flowing powders, flakes, bars, pellets, or tablets. The surface-active properties of two commercial detergents based on this discovery are reported. Besides showing the excellent detergency of these products in washing artificially soiled cotton, it has been shown that they enhance the detergency of alkalibuilt sodium alkylaryl sulfonates in hard water.

Soap-based detergent formulations: X. Nature of detergent deposits

The cumulative deposition of detergent residue on unsoiled cotton and polyester-cotton permanent press finish cloth was determined for a variety of detergent formulations after washing 25 consecutive times in 300 ppm hard water in a laboratory Tergotometer. Included in this study were: a phosphate-built laundry detergent, two carbonate-built detergents, tallow soap and various tallow soap formulations with anionic and amphoteric lime soap dispersing agents, and a glassy sodium silicate. Sample swatches washed with each formulation were analyzed for calcium, magnesium, and organic acid content. Fabric washed with the carbonate detergents showed the highest calcium and magnesium content, while those washed with the phosphate detergent and the soap-lime soap dispersant-builder formulations had the lowest. Fabric washed with soap alone had a much higher fatty acid residue than those washed with the other detergent formulations. However, the amount of organic acids left on the fabric after washing with a soap-lime soap dispersing agent formulation was no greater than that produced by phosphate- and carbonate-built detergents. The presence or absence of deposits also was verified visually with a scanning electron microscope. Each formulation also was tested for detergency by measuring the soil buildup in a multiwash procedure. Generally, the buildup of soil paralleled the deposit of detergent residue on the unsoiled cloths.
