酒店布草PH值超標，床單會(hui) 燒臉，經過調查的諸多酒店，不管是平價(jia) 的快捷酒店還是高星級的豪華酒店，重點測試毛巾和床單的酸堿值，結果是大跌眼鏡的。有些酒店的毛巾用手觸摸有明顯滑潤的油膩感，經驗豐(feng) 富的客房主管、經理或房務總監、總經理等，馬上就會(hui) 知道這是未清洗幹淨造成的。這種情況下的毛巾，用肉眼看上去與(yu) 正常清洗後的毛巾無異常情況，但在陽光下照射下會(hui) 出現黑色的區域，這種情況稱之為(wei) “黑團”，“黑團”造成的原因是毛巾多次清潔不幹淨，汙垢吸附於(yu) 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、各飯店使用的洗衣設備型號、性能各不相同，因此必須製訂相應的洗滌工藝和洗滌程序。製訂洗滌工藝的主要技術參數為(wei) ：洗滌時間、溫度、速度、程序、洗滌劑的合理用量以及裝載量等。而洗滌程序又與(yu) 水質、被洗物的狀況、洗滌化學品、洗滌設備以及水位的選擇等相關(guan) 。

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、洗滌物品的紡織原料各有不同，如：全棉、滌棉、滌綸等，也應按不同的品質製訂不同的洗滌工藝。如：全棉和滌棉的洗滌溫度不同，滌棉主洗溫度

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、洗滌物品的數量取決(jue) 於(yu) 洗衣設備的容量，在含有一定比例化學品的洗滌水中，投入超量或不足量的洗滌物品都會(hui) 影響到洗滌效果和物品的牢度。

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、注意選用優(you) 質適用的洗滌劑，並針對不同的洗滌對象和洗滌環境配製合理的用量，若不區別洗滌對象，亂(luan) 用洗滌劑，不僅(jin) 影響洗滌效果，嚴(yan) 重時還會(hui) 損壞紡織品。

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、洗滌前應首先按使用用途對被洗物進行分類，如：台布、床單、毛巾、被套、枕套等，然後按同類用品的顏色進行分類，不同顏色的一塊處理可能會(hui) 引起互相汙染，不同顏色的同類物品處理方法也不相同，特別是漂白和有色的不能混在一起處理。還要按汙垢程度分類，一般分為(wei) 重垢、中垢、輕垢三類。浴巾、地巾、手巾和麵巾的厚薄和柔軟度不一樣，受汙染程度不同，如果混在一起洗滌，容易引起超量的磨擦，因此，這四種毛巾可分為(wei) 三類洗滌，浴巾一類、地巾一類、手巾和麵巾一類。

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.
