Deterioration related to detergent
1. When washing, the feeding method is not correct. The feeding port is provided on the side of the eluting machine, which is not only convenient for detergent addition, but also for ensuring the safety during the washing process of the cloth. Many washing workers are used to adding detergent before or after loading the cloth, and then closing the door and adding water. This has many drawbacks. At present, the market is still dominated by high-temperature detergents. The detergents are mostly alkaline, and they are directly in contact with the cloth. During the process of adding water, high heat and violent reaction occur in the instant of water, which is easy to burn and break the holes.
2. The feeding time is not correct when washing. It is not possible to feed the cloth when it is not completely wetted, which will still cause partial damage to the cloth or the role of the detergent in the water.
3. Improper use of bleach and neutralizing acids. If the temperature is not used properly, the use concentration is too high, and excessive residue after washing will reduce the service life of the cloth.
4. The cloth is stained with corrosive chemicals. Some of the cleaning products used in the hotel are corrosive, especially some strong acid cleaners have a great influence on the linen. If the waiter collects or cleans the room, the cloth is inadvertently stained with these detergents and is not cleaned immediately. It will also cause partial damage to the cloth and the poorness of the cloth. (This will cause the laundry to find the cause of the damage)
5. The detergent selection is wrong. Cleaners are chemical raw materials, which require certain knowledge and responsibility and are used correctly. Otherwise, there may be mixed detergents and even incorrect feeding, which not only fails to achieve the cleaning effect, but also causes damage.
6. The washing time is too short, the number of times is small, the detergent residue will increase, and it is easy to cause damage to the cloth.
7. Wrong washing procedure. Unneutralized removal of residual alkali, residual chlorine, etc. will also accelerate the life of the linen.
Device related factors
1. The drum of the washing machine or the inner tank of the washing dragon has burrs or some parts are not smooth. It is likely to cause the cloth to be scratched or worn during the washing process, which is characterized by drawn yarn, secondary yarn, and then small holes. And gradually expand.
2, some inferior elution machines due to poor manufacturing process and design, the gap between the liner and the door is too large, it is easy to cause the tear of the cloth, this phenomenon is not uncommon.
3. Don't pay attention when closing the door after installation, the cloth is caught by the door. When the washing is started, the drum rotates, causing the cloth to tear and damage.
4. When the polyester is dehydrated, the cloth is not well distributed or the high removal time is too long or the high rotation speed is too high, and the strong mechanical force causes the cloth to be damaged.
5. During the ironing process, the cloth should pay attention to the direct running speed ratio of the ironing machine drum, and the speed ratio when the ironing machine is connected with the folding machine, and the cloth is required to pass through. Pulling or stacking will have an impact on the life and strength of the cloth.
6. Press dehydration burst. The use of laundry dragons has become more and more popular, and the laundry factory must adjust the appropriate pressure according to the different fabrics and characteristics of the cloth. If the press dewatering machine is improperly adjusted, too high a pressure will cause the impact of water on the cloth, and bursting; if the pressure is too low, the water content is too high, which affects the efficiency and energy consumption of the finishing.
7. The ironing or drying temperature is too high. Different fabrics have different temperature resistance, and simply increasing the temperature in pursuit of efficiency will also cause embrittlement loss of the cloth. The absence of cold air after drying of the dryer can also cause fiber embrittlement of the textile.
8. Excessive temperature washing will also cause loss of linen fibers.
Human and other factors
1. The inspection work before washing is not serious, so that some sharp or hard debris is mixed in it, causing the cloth to be damaged during washing.
2. Or sorting problem, many laundry plants in order to speed up the speed without heavy and heavy sorting, often increase the amount of detergent during washing, resulting in the loss of linen; there is mixed polyester or cotton The damage caused by washing, the degree of tolerance of the two and so on are all different.
3. Transportation problems. Regardless of the transfer of the linen truck in the workshop or the transportation between the laundry factory and the hotel, it is easy to cause tearing, squeezing and hooking, which will inevitably cause damage to the linen.
4. Linen storage environment. The cloth must be stored in a moisture-proof manner, the warehouse should be well ventilated, and the edge of the warehouse shelf should be smooth. At the same time, the linen house should avoid pests and rodents.
5. Heavy stains of cloth alone to remove stains caused by burns. Some linens need to be picked for separate pretreatment. If the concentration of detergent used in the pretreatment is too high, it will easily cause damage to the linen.
6. When the installed capacity is too much or too little during the washing process, the machine will be pulled when it is high.
7. The iron content in the cleaning cloth is excessive. When the oxidant is in the process of action, the rust will play a catalytic role, and the severe oxidation reaction may cause damage.
8. Excessive water hardness and excessive residual calcium and magnesium compounds can cause damage, especially when using soap-based cleaners.
9. The selection of the washing program is wrong. Many people think that the longer the washing time, the cleaner the stain removal, which is also a misunderstanding. Excessive washing time will accelerate the wear and tear of the cloth and cause damage.
Cloth itself
Why the same laundry in the same laundry factory, the life of different customers will be different, which is obviously caused by the difference in the quality of the cloth. Different fiber qualities and weaving processes directly affect the number of times it is washed. When the fiber strength of the cloth drops to a certain critical point, normal washing will also cause a lot of tearing. This is why some washes are carried out in accordance with regular washing procedures and production specifications, and the cause of breakage occurs when the number of washings is small.
Although the washing industry is engaged in linen washing, for a long time, people don't know much about the subject matter we deal with. Nowadays, with the start of the rental market, more and more people are paying attention to the textile itself.
Regarding the quality of the cloth itself, it is recommended that the laundry factory communicate with the customer in depth when it undertakes the business, and at the same time communicate with the linen supplier. Of course, we suggest that the laundry factory should be able to find the professional inspection agency for the linen. Regular testing.
Of course, we have only summarized some common factors that cause the damage of the cloth. You may have many situations in the actual production and operation. Welcome to add a message!
