The visual manifestation of silicon spots on the surface of clothing is the appearance of oil spots as small as a pin tip or as large as a rice grain. Under extreme conditions, the area may be larger. Sometimes the oil spots have a certain color due to floating color. The spots are like small wet spots. It feels soft and grain-free, and is extremely difficult to spot and remove before drying. �究其因是硅油破乳漂油导致，常出现在免烫整理和水洗过软工艺后� �</p
When preparing non-iron lotions, in order to reduce the impact of resin finishing, silicone oil is often added to improve brightness, smoothness and tearing strength. Most of them are amino silicone oil, large breast type hydroxyl silicone oil or compound silicone oil softener. Now they are also starting to Applications of multi-component copolymerized silicone oil In addition to selecting the appropriate silicone oil when applying, be sure to follow the correct ingredient dilution process. Use it after 1-2 hours after preparation. Check the surface of the potion for floating objects and delamination before use. Also during the process of soaking clothing To check whether there is any change in the status of the medicine, it is recommended to use a medicine soaking machine or a medicine sprayer In addition to the structure, cationicity and emulsification level of silicone oil, the phenomenon of demulsification of floating oil is mainly caused by the anionicity of resin, strong electrolyte of catalyst, water hardness and clothing fabrics such as PH value and other factors that interfere with the residual liquid. Due to high temperature setting reasons, it is not necessary to After the ironing process is completed, the problem of silicon spots is found. There is currently no good way to eradicate it. It mainly depends on preliminary inspection and strict implementation of the process. �</p
When water washing is too soft, due to the previous process environment, the fermentation washing process generally has fewer problems than the general washing process. General washing often uses alkali agents during desizing. Direct softening after insufficient removal of the alkali agent is prone to problems. Other processes If there is color registration, bleaching, and frying before softening, Processes such as frying and bleaching are caused by the use of strong electrolyte powder, coarse salt to promote dyeing or soda ash, caustic soda, and phosphate to fix the color, or the use of strong oxidants such as high manganese with phosphoric acid, hydrogen peroxide, bleaching water, or the use of pumice, fiber fragments, etc. Chips and other reasons may lead to the occurrence of silicon plaque. �就此而言，我们坚持的原则是：加软前服装要充分的清水过干净，必要时加软前后一道过清水加适量醋酸或渗透剂（工厂枧油也可）调整� In terms of operation: Do not turn on steam to heat up the water machine after adding silicone oil; the softening temperature should not exceed 60°C (for conventional silicone oil); do not add anionic additives such as anionic penetrants, chelating dispersants, etc.; try to avoid adding strong ones later. Electrolyte raw materials such as salt, soda ash, caustic soda, etc.; when adding silicone oil, the machine must be turned on; do not stop the machine after adding soft and draining the liquid. �</p
这里有一个判断氨基硅油乳化是否充分的直观办法：将硅油稀释5至10倍，静置30分钟后观察稀释液表面，如果有漂油或拉丝现象，则此硅油使用时要小心谨慎。
For the removal of silicon plaque, the current effective low-cost method is to spray the silicon plaque clothing part with gasoline, and then put the clothing in a sealed plastic bag or a closed bucket. There should be enough gasoline at the bottom of the bag or bucket. After leaving it for 20-60 minutes, take the garment out of the machine and wash it thoroughly with detergent. The silicon plaque removal effect is ideal, but there is a residual gasoline smell. You can use emulsified detergent to fully wash it to remove it, or you can cover up the fragrance smell. �此外，如果是含有涤纶纤维的面料且未经整烫，可使用异丙醇充分浸泡，20-24小时后清洗的方法，此法对涤纶损伤微乎其微� �纯棉面料且未经整烫，也可使用异丙醇浸泡法� �因时间问题，未做其他溶剂去除试验效果评价，待大家实践�
