The warm down jacket is the favorite of many people in winter every year, but although the down jacket is very warm, it is very troublesome to clean, and the machine wash is easy to explode, which is said every year, but similar accidents still continue. Again, washing down clothes by washing machine is likely to explode!
Why does the machine wash down jacket explode? First, the outer layer of the down jacket is generally provided with a waterproof coating. When the down jacket is dried at high speed, the water saturated one will expand continuously after dehydration, and air will be produced in the down jacket, and the waterproof coating is not conducive to the gas discharge, so the down jacket will continue to be enlarged, and the washing machine will be full, which may cause an explosion -- this principle is similar to the balloon explosion;
Second, electrostatic charge will be generated on the inner wall of down jacket and washing machine in the process of drying. A large amount of heat generated by electrostatic charge will explode in a short time, which is likely to cause similar explosion phenomenon. Most of the new washing machines are equipped with down clothes washing function. These washing machines are set with low speed of 600 or 800 rpm, which are suitable for down clothes washing. Some washing machines can also be adjusted automatically according to the washed clothes.
There is a layer of waterproof and windproof grease on the surface of down jacket, which leads to poor air permeability, but it is very warm. Remember that down jacket cannot be dry cleaned. After dry cleaning, the grease will disappear and reduce the warmth preservation of down jacket. In addition, down jacket can be washed three or four times a year, and can be machine washed or hand washed.
Which type of laundry has an explosion?
Wave wheel washing machine, especially the old two cylinder wave wheel washing machine
Why does washing machine dry down jacket explode?
Experts explain: due to the light weight and poor air permeability of down jacket, after washing, the filled down will gather together, thus creating a large area of gap in down jacket. In the high-speed drying process, the feathers that have been saturated with water will expand continuously after dehydration, and air will be generated in the down jacket. However, the waterproof coating is not conducive to the gas discharge, so it will continue to expand the down jacket and fill the washing machine. In addition, the dry nylon cloth and down will generate static electricity. The large amount of heat generated by static electricity will explode in a short time, while the space in the washing machine is limited, and the gas will gather To a certain extent, it may cause 'explosion'.
