一、洗涤大浴巾使用的水质较硬

1、 The water used for washing large bath towels is relatively hard

大浴巾变黄的一个原因就是洗涤的水质较硬，未经软化的水会含有大量的的有机盐和无机盐，这些以离子状态存的盐中包括钙、镁、铁、锌、锰离子，在洗涤过程中会沉积在织物上甚至会进入纤维内部。随着水洗次数的增加，沉积量会越来越多。从而导致酒店浴巾发灰、变硬。如果用地下水，现象会更严重。酒店浴巾

One reason for the yellowing of a large bath towel is that the washing water is hard. Unsoftened water will contain a large amount of organic and inorganic salts, including calcium, magnesium, iron, zinc, and manganese ions in the ionic state. During the washing process, they will deposit on the fabric and even enter the interior of the fiber. As the number of washes increases, the deposition amount will increase. As a result, the hotel towel turns gray and hard. If groundwater is used, the phenomenon will be more serious. Hotel towel

二、洗涤大浴巾时漂洗不干净

2、 Washable when washing large bath towels

1、洗涤剂质量差或添加量少

1. Poor quality or low amount of detergent added

这个原因是其中的一个主要的原因，使用差的洗涤剂并不能完全的洗净衣物，长期下去，污垢的积累，洗涤剂的残留，衣物就会变黄。所以不仅需要的洗涤剂，还需要洗衣工人需熟练掌握洗涤剂的投放量、时间和温度。

This is one of the main reasons, as using poor detergents cannot completely clean clothes. Over time, the accumulation of dirt and residual detergent can cause clothes to turn yellow. So not only do we need professional detergents, but laundry workers also need to be proficient in the amount, time, and temperature of detergent used.

2、漂洗不彻底

2. Incomplete rinsing

在使用全自动的工业洗衣机洗涤的时候，在洗涤之后，有一道漂洗的程序，如果漂洗的水量不够，或者漂洗的时间过短，就会造成漂洗不彻底，洗下的污垢又均匀地附着在被洗涤织物上，也会造成织物变黄。

When using a fully automatic industrial washing machine for washing, there is a rinsing process after washing. If the rinsing water is insufficient or the rinsing time is too short, it will cause incomplete rinsing, and the washed dirt will evenly adhere to the washed fabric, which will also cause the fabric to turn yellow.

3、使用含氯漂白剂后未进行脱氯处理

3. No dechlorination treatment after using chlorine containing bleach

有的纺织厂会用含氯的漂白剂进行漂白，但是如果没有进行脱氯这一道工序的话，氯会残留在织物上，会造成布草发黄。酒店浴巾

Some textile factories use chlorine containing bleach for bleaching, but if the dechlorination process is not carried out, chlorine will remain on the fabric and cause the fabric to turn yellow. Hotel towel

酒店布草浴巾变黄之后该怎么处理呢？好的办法就是采用彩漂洗衣粉，但是要使用热水（一般需60℃以上），洗后投水漂洗，全自动的洗脱机可以用蒸汽对冷水进行加热，从而达到这一温度。如发黄严重使用还原剂还原处理（温度60℃左右，浴比1：20水），5分钟后正常投水即可。

What should I do after the hotel linen bath towel turns yellow? A good solution is to use color bleached laundry detergent, but hot water (usually above 60 ℃) should be used. After washing, water should be added for rinsing. The fully automatic washing machine can use steam to heat the cold water to reach this temperature. If severe yellowing occurs, use a reducing agent for reduction treatment (temperature around 60 ℃, bath ratio 1:20 water), and then add water normally after 5 minutes.

酒店宾馆在把酒店浴巾交给洗衣厂的时候，要仔细的考察洗衣厂洗涤是不是干净，洗涤设备是否，尽量挑那些规模大，技术比较的洗衣厂。有了优质设备、洗涤技术和洗涤剂的三重保证，酒店浴巾洗起来更省心。更多相关事项就来我们网站http://www.jnadx.com咨询吧！
