產品洗后變灰？
Does the product turn gray after washing?
主要原因是
酒店布草長期漂洗不徹底，不能較徹底地清除布草中的雜質。水質是重要因素，如果是滾筒式洗滌，也可能是漂洗程序不夠；如果是隧道式洗衣龍，可能是在漂洗過程中也使用回收水，而回收水的質量也很重要。
The main reason is that the hotel linen is not thoroughly rinsed for a long time and cannot completely remove impurities from the linen. Water quality is an important factor, and if it is drum washing, it may also be due to insufficient rinsing procedures; If it is a tunnel type laundry dragon, it may be that recycled water is also used during the rinsing process, and the quality of recycled water is also important.
產品洗后變黃？
Does the product turn yellow after washing?
主要原因有兩個：一是漂白不徹底，二是水質。棉花天然的顏色是黃色的，布草在生產的過程中通過漂白將纖維漂成白色，但是在后續的使用過程中，需要不斷漂白來維持白色。
There are two main reasons: one is incomplete bleaching, and the other is water quality. The natural color of cotton is yellow, and cloth grass bleaches the fibers to white during the production process. However, in the subsequent use process, continuous bleaching is needed to maintain the white color.
漂白分為氯漂和氧漂，國內現在越來越多地使用氧漂，氧漂對溫度的要求較高。如果達不到規定溫度，氧漂劑也不能發揮應有的作用。
Bleaching is divided into chlorine bleaching and oxygen bleaching. Oxygen bleaching is increasingly used in China, and oxygen bleaching has high temperature requirements. If the specified temperature is not reached, the oxygen bleaching agent cannot play its due role.
毛巾產品勾圈？
Towel product loop?
毛巾產品勾圈分為洗滌前和洗滌后。
The towel products are divided into pre washing and post washing hooks.
洗滌前：毛巾在洗滌前尚未縮水，織物較為松散，此時，毛巾有的三維織造模式使毛圈較易被拉出，因此要特別注意新毛巾的操作流程。
Before washing: The towel has not yet shrunk before washing, and the fabric is relatively loose. At this time, some three-dimensional weaving patterns of the towel make it easier for the loops to be pulled out, so special attention should be paid to the operation process of the new towel.
從開箱、洗滌、烘干、折疊運送至房間的所有流程都需要定期檢查是否有尖銳處，例如相關設備的內表面、回收客用毛巾的運輸通道等，以免造成額外的傷害。
All processes from unpacking, washing, drying, folding and transportation to the room require regular inspection for sharp points, such as the inner surface of relevant equipment, the transportation channel for recycling guest towels, etc., to avoid additional injuries.
洗滌后：洗滌過3-5次的毛巾已經縮水，毛圈不容易被拉出。排除上述物理因素，毛巾勾圈有可能發生在離心脫水這個環節。
After washing: The towel that has been washed 3-5 times has shrunk and the loops are not easily pulled out. Excluding the above physical factors, towel loops may occur during the centrifugal dehydration process.
酒店一般使用滾筒式的洗滌設備，毛巾洗滌后通過滾筒高速旋轉產生離心力脫水。滾筒直徑越大，轉速越快，離心力越大，毛巾產生勾圈的可能性越大。強力的離心力也會帶來其他不可修復的物理損傷，例如撕裂等。
Hotels generally use drum type washing equipment, and after washing towels, centrifugal force is generated through high-speed rotation of the drum for dehydration. The larger the diameter of the drum, the faster the rotational speed, and the greater the centrifugal force, the greater the possibility of towel curling. The strong centrifugal force can also cause other irreparable physical damage, such as tearing.
That's all for the common problems encountered after washing the hotel linen. I hope you can be helpful. For more information, please come to our website http://www.caibozheng.cn Consulting!
