产品洗后变灰？
Does the product turn gray after washing?
主要原因是
酒店布草长期漂洗不彻底，不能较彻底地清除布草中的杂质。水质是重要因素，如果是滚筒式洗涤，也可能是漂洗程序不够；如果是隧道式洗衣龙，可能是在漂洗过程中也使用回收水，而回收水的质量也很重要。
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.
产品洗后变黄？
Does the product turn yellow after washing?
主要原因有两个：一是漂白不彻底，二是水质。棉花天然的颜色是黄色的，布草在生产的过程中通过漂白将纤维漂成白色，但是在后续的使用过程中，需要不断漂白来维持白色。
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.
漂白分为氯漂和氧漂，国内现在越来越多地使用氧漂，氧漂对温度的要求较高。如果达不到规定温度，氧漂剂也不能发挥应有的作用。
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.
毛巾产品勾圈？
Towel product loop?
毛巾产品勾圈分为洗涤前和洗涤后。
The towel products are divided into pre washing and post washing hooks.
洗涤前：毛巾在洗涤前尚未缩水，织物较为松散，此时，毛巾有的三维织造模式使毛圈较易被拉出，因此要特别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.
从开箱、洗涤、烘干、折叠运送至房间的所有流程都需要定期检查是否有尖锐处，例如相关设备的内表面、回收客用毛巾的运输通道等，以免造成额外的伤害。
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.
洗涤后：洗涤过3-5次的毛巾已经缩水，毛圈不容易被拉出。排除上述物理因素，毛巾勾圈有可能发生在离心脱水这个环节。
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.
酒店一般使用滚筒式的洗涤设备，毛巾洗涤后通过滚筒高速旋转产生离心力脱水。滚筒直径越大，转速越快，离心力越大，毛巾产生勾圈的可能性越大。强力的离心力也会带来其他不可修复的物理损伤，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.jnadx.com Consulting!
