為什么過量使用彩票网站代理加盟群會降低織物的白度?

  彩票网站代理加盟群有很多種。雖然各種增白劑的化學結構和功能不盡相同,但增白纖維或織物的原理是相同的。
  There are many kinds of fluorescent whitening agents. Although the chemical structures and functions of various whitening agents are different, the principles of whitening fibers or fabrics are the same.
  美白原理主要是因為增白劑分子含有共軛雙鍵系統,與優秀的平面性,這種特殊的分子結構在陽光下能吸收陽光,紫外線(300 ~ 400 nm波長)和宣布紫光(波長為420 ~ 500 nm),紫光和黃色光纖維或織物混合而成白光,白色的纖維或織物。
  The whitening principle is mainly because whitening agent molecules contain conjugated double bond system and excellent planarity. This special molecular structure can absorb sunlight in sunlight, ultraviolet (300-400 nm wavelength) and declare purple (420-500 nm wavelength), purple and yellow optical fibers or fabrics are mixed to form white light, white fibers or fabrics.

  彩票网站代理加盟群的增白效果只是光學增白和補色,不能代替化學漂白,所以不漂白的織物直接用彩票网站代理加盟群進行增白,增白效果并不理想。根據彩票网站代理加盟群的原理,增白劑的增白效果主要取決于陽光中紫外線的含量和彩票网站代理加盟群在纖維或織物上的濃度。

  The brightening effect of fluorescent whitening agent is only optical whitening and complementary color, which can not replace chemical bleaching. Therefore, the non-bleached fabrics are directly whitened by fluorescent whitening agent, and the whitening effect is not ideal. According to the principle of fluorescent whitening agent, the whitening effect of fluorescent whitening agent mainly depends on the content of ultraviolet rays in sunlight and the concentration of fluorescent whitening agent on fibers or fabrics.
  當陽光中uv含量足夠時,彩票网站代理加盟群對織物的濃度會發生一定程度的變化,隨著增白劑濃度的增加,彩票网站代理加盟群對織物的增白效果增強。
  When the UV content in sunlight is enough, the concentration of fluorescent whitening agent on the fabric will change to a certain extent. With the increase of the concentration of whitening agent, the whitening effect of fluorescent whitening agent on the fabric will be enhanced.
  但當增白劑的濃度適當的濃度,其比較好的美白效果,可以達到比較高的白度值,如果光亮劑的數量超出比較優濃度,不僅不能改善織物的增白效果而不是下降(即一般織物泛黃、白度下降),目前,增白劑叫增白劑黃點的比較佳濃度。
  But when the concentration of whitening agent is appropriate, its best whitening effect can reach the highest whiteness value. If the amount of brightener exceeds the optimal concentration, it can not improve the whitening effect of fabrics, but not decrease (that is, yellowing and whiteness decrease of general fabrics). At present, the best concentration of whitening agent is called the yellowing point of whitening agent.
  那么,為什么美白效果不再是增強以及增加織物的彩票网站代理加盟群濃度,主要原因是:因為織物上的黃燈的力量是有限的,因此抵消黃燈(主波長約為570納米)需求發出黃色的光吸收紫外線彩票网站代理加盟群,光的互補色,紫光是有限的。
  Then, why the whitening effect is no longer to enhance and increase the concentration of fluorescent whitening agent on fabrics, the main reason is: because the strength of yellow light on fabrics is limited, so offset the need of yellow light (main wavelength is about 570 nanometers) to emit yellow light absorption ultraviolet fluorescent whitening agent, complementary color of light, purple light is limited.
  增加彩票网站代理加盟群對織物發出的藍光和紫外光的強度,以抵消織物上的一些黃光。隨著黃光強度的逐漸降低,織物變得越來越白。
  Increase the intensity of blue and ultraviolet light emitted by fluorescent whitening agent to offset some yellow light on the fabric. As the intensity of yellow light decreases, the fabric becomes whiter and whiter.
  當織物上的彩票网站代理加盟群的濃度添加到適當的濃度(即泛黃的光亮劑),藍色的強度紫光發出的光亮劑就等于織物上的黃色光的強度,而互相抵消。此時織物也是比較白的,增白劑也是比較好的。
  When the concentration of fluorescent brightener is added to the appropriate concentration (i.e. yellowing brightener), the intensity of blue purple light emits brightener equal to the intensity of yellow light on the fabric, and offset each other. At this time, the fabric is also the whitest, whitening agent is also the best.
  當紫光強度超過抵消織物強度上的黃燈,增白劑通過反射LanZiGuang反映非常明顯,同時因為增白劑的各種團體不相同,不同的顏色,如綠色淺紫色,紅色,藍色,等等)是明顯的,這兩個元素的感應效果,使織物添加灰色的顏色,與添加增白劑的作用濃度和加強,使增白功能下降,雖然此時織物上沒有黃色的痕跡,但也不再嬌艷奪目,光彩照人。
  When the intensity of purple light exceeds the yellow light which counteracts the strength of the fabric, the brightener reflects very clearly by reflecting LanZiGuang. At the same time, because different groups of brighteners are different, different colors, such as green, light purple, red, blue, etc.) are obvious. The inductive effect of these two elements makes the fabric add grey color, and add whitening agent. The whitening function decreases with the action concentration and strengthening. Although there is no yellow mark on the fabric at this time, it is no longer charming and shining.
  因此,在選擇增白劑時,除了考慮其增白效果外,還通過小樣本實驗,尋找不同增白劑對織物黃變點的影響,以便合理使用,以獲得比較佳的增白效果。
  Therefore, in the selection of whitening agent, in addition to considering its whitening effect, small sample experiments were conducted to find out the effect of different whitening agents on the yellowing point of fabrics, so as to achieve the best whitening effect.
