酒店布草PH值超标，床单会烧脸，经过调查的诸多酒店，不管是平价的快捷酒店还是高星级的豪华酒店，重点测试毛巾和床单的酸碱值，结果是大跌眼镜的。有些酒店的毛巾用手触摸有明显滑润的油腻感，经验丰富的客房主管、经理或房务总监、总经理等，马上就会知道这是未清洗干净造成的。这种情况下的毛巾，用肉眼看上去与正常清洗后的毛巾无异常情况，但在阳光下照射下会出现黑色的区域，这种情况称之为“黑团”，“黑团”造成的原因是毛巾多次清洁不干净，污垢吸附于毛巾上形成的。

The pH value of hotel linen exceeds the standard, and bed sheets can burn the face. After investigation, many hotels, whether they are affordable express hotels or high star luxury hotels, focused on testing the pH value of towels and bed sheets, and the results were surprising. Some hotel towels have a noticeable slippery and greasy feeling when touched by hand. Experienced room supervisors, managers, room directors, and general managers will immediately know that this is caused by not cleaning thoroughly. In this situation, the towel may appear normal to the naked eye after cleaning, but black areas may appear when exposed to sunlight, which is called "black clumps". The reason for "black clumps" is that the towel is not cleaned thoroughly multiple times, and dirt is adsorbed onto the woolen towel.

一、各饭店使用的洗衣设备型号、性能各不相同，因此必须制订相应的洗涤工艺和洗涤程序。制订洗涤工艺的主要技术参数为：洗涤时间、温度、速度、程序、洗涤剂的合理用量以及装载量等。而洗涤程序又与水质、被洗物的状况、洗涤化学品、洗涤设备以及水位的选择等相关。

1、 The types and performance of laundry equipment used in different restaurants vary, therefore corresponding washing processes and procedures must be developed. The main technical parameters for formulating washing processes include washing time, temperature, speed, program, reasonable amount of detergent, and loading capacity. The washing process is also related to water quality, the condition of the washed object, washing chemicals, washing equipment, and the selection of water level.

二、洗涤物品的纺织原料各有不同，如：全棉、涤棉、涤纶等，也应按不同的品质制订不同的洗涤工艺。如：全棉和涤棉的洗涤温度不同，涤棉主洗温度

2、 The textile materials used for washing items are different, such as all cotton, polyester cotton, polyester, etc., and different washing processes should be formulated according to different qualities. For example, the washing temperature of pure cotton and polyester cotton is different, and the main washing temperature of polyester cotton is different

三、洗涤物品的数量取决于洗衣设备的容量，在含有一定比例化学品的洗涤水中，投入超量或不足量的洗涤物品都会影响到洗涤效果和物品的牢度。

3、 The quantity of washing items depends on the capacity of the washing equipment. In washing water containing a certain proportion of chemicals, adding an excessive or insufficient amount of washing items can affect the washing effect and the fastness of the items.

四、注意选用优质适用的洗涤剂，并针对不同的洗涤对象和洗涤环境配制合理的用量，若不区别洗涤对象，乱用洗涤剂，不仅影响洗涤效果，严重时还会损坏纺织品。

4、 Pay attention to selecting high-quality and suitable detergents, and prepare reasonable amounts for different washing objects and environments. If you do not distinguish the washing objects and use detergents indiscriminately, not only will it affect the washing effect, but in severe cases, it will also damage the textiles.

五、洗涤前应首先按使用用途对被洗物进行分类，如：台布、床单、毛巾、被套、枕套等，然后按同类用品的颜色进行分类，不同颜色的一块处理可能会引起互相污染，不同颜色的同类物品处理方法也不相同，特别是漂白和有色的不能混在一起处理。还要按污垢程度分类，一般分为重垢、中垢、轻垢三类。浴巾、地巾、手巾和面巾的厚薄和柔软度不一样，受污染程度不同，如果混在一起洗涤，容易引起超量的磨擦，因此，这四种毛巾可分为三类洗涤，浴巾一类、地巾一类、手巾和面巾一类。

5、 Before washing, the items to be washed should be classified according to their intended use, such as tablecloths, bed sheets, towels, duvet covers, pillowcases, etc. Then, they should be classified according to the colors of similar items. Treating items of different colors together may cause mutual contamination, and the treatment methods for similar items of different colors are also different, especially for bleached and colored items that cannot be mixed together. It should also be classified according to the degree of dirt, generally divided into three categories: heavy dirt, medium dirt, and light dirt. The thickness and softness of bath towels, floor towels, hand towels, and face towels vary, and the degree of contamination varies. If mixed together for washing, it can easily cause excessive friction. Therefore, these four types of towels can be divided into three categories for washing: bath towels, floor towels, and hand towels and face towels.
