Silk fabrics are soft, delicate, and brightly colored. They are called girls' fabrics, so they should be cherished and loved. Careful maintenance and collection should be taken to prevent pollution and damage.
Silk clothing should be thoroughly washed in the collection, it is best to dry clean once, which not only can decontaminate but also protect the material and shape, and at the same time can play the role of insecticide sterilization.
The washed silk clothes should be ironed and shaped to make the surface smooth and smooth, and enhance the anti-pollution ability. Silk fabrics have poor color fastness and should not be exposed to direct sunlight, so as to avoid fading and affect the vividness of color.
When silk clothing is in collection, white silk is best wrapped in blue paper to prevent yellowing. Brightly colored silk clothing should be wrapped in dark paper to keep the color intact.
Silk clothing is lighter, less squeezing, and wrinkled. It should be stored separately or placed on the upper layer of the suitcase.
Velvet clothing such as gold velvet must be hung up and stored with a hanger to prevent the pile from being pressed and fluffed or deformed, thereby damaging the clothes and affecting the appearance.
Silk clothing should be stored separately from suede and woolen clothing, and also stored separately to prevent cross-color.
Silk clothing is also mildewed by moisture, and it is easy to attract insects, so keep it dry when collecting. Also use some anti-caries agents to prevent insects.
When the silk clothing is slightly mildewed due to dampness, it can be gently rubbed with flannel or a new towel. When the mold is fine, when it is serious, it can be sprayed on the surface of the silk fabric with ammonia water, and then ironed with iron, and the mildew can be eliminated. A slight mildew on the white satin, gently rubbed with alcohol.

1. Product introduction
Coal-based Column Denitrification Column Activated Carbon is cylindrical black particles. It has many characters, such as high porosity, high sulfur capacity, high desulfurization efficiency, large surface area, light weight, strong adsorption capacity, wear resistance, good water resistance, low air resistance, easy regeneration, not easy to break under high pressure etc. It is a commonly used in adsorbent.
2. Adsorption purification principle and process
Coal-based denitrification Activated Carbon is divided into large pores (pore size greater than 50nrrt), the middle hole (pore size between 2 ~ 50nm) and micro-pore (pore size less than 2nm) three categories.
The denitrification activated carbon is by active carbon`s adsorption and catalytic activity of activated carbon. The strong catalytic effect of the active carbon for sulfur dioxide in gas, and a small amount of Oxygen in the oxidation reaction, the reaction of elemental S adsorbed the surface of activated carbon. When activated carbon desulfurization agent the adsorption reaches saturation, the desulfurization efficiency decreased obviously, it must carry on the regeneration. The regeneration of active carbon adsorption depends on the material, sulphur began to melt under atmospheric pressure is 190 degrees, 440 degrees Celsius will sublimate into gas, therefore, the general use of superheated steam temperature of about 450-500 degrees Celsius for the regeneration of activated carbon desulfurization agent. When the desulfurization agent reach high temperature, the elemental sulfur separate out activated carbon, the precipitation of sulfur into sulfur recovery pool, water cooled to form solid sulfur.
