What is the material of spray nonwoven

The main use of sprayed nonwoven in our lives is very common, especially in winter, it is indispensable. How much do you know about it? What is the material of spray nonwoven? What is the difference between spray nonwoven and non-bonded nonwoven? Today, I will introduce Jinqiao Nonwovens to us here.
What is the material of spray nonwoven?
Coated nonwoven, also known as shotcrete, is a kind of non-woven fabric. The working principle of the structure is that the adhesive is sprayed on both sides of the bulky fiber layer. Because of the working pressure under spraying and the adsorption force of the lower vacuum pump, the adhesive can also penetrate into the inner structure of the fiber layer, and the fiber layer after spraying is dried and solidified, so that the nodes in the middle of the fibers are bonded, but not The fibers that stick to each other still have great playability.
Also spewing publicity is already known as vacuum pump indoor space nonwoven or nonwoven, which is made of pure natural fibers based on stretched nonwoven, rayon or generated fibers, finishing, super glue, baking curing treatment. Because of its cashmere content, compressibility, resilience, resistance to dry, wet cleaning, light and heat, it has in recent years turned into ski shirts, nonwoven manufacturing, aerospace suits and quilts, outdoor sleeping bags, bedding kits , and some of its main raw materials and chemicals.
Characteristics of spray nonwoven
Due to its structural design principle and the development trend of manufacturing technology, the sprayed nonwoven has a porous structure, high bulkiness, cold-proof and warm-keeping effect, high shrinkage resilience, dry and wet cleaning resistance, light weight, softness and more comfort, etc. characteristic.
The main purpose of spray nonwoven
Its main use can be said to be very common, ideal filling material for all kinds of winter clothing, bedding sets, home accessories, in recent years, it has become the production and processing of nonwoven clothes and ski shirts, space suits and quilts, outdoor sleeping bags The main raw materials for bedding kits and some chemical products.
Is collodion harmful?
The gushing has no side effects. In the initial stage, due to the backward processing technology, the quality of the selected adhesive is relatively poor. In order to be able to stick together, the fibers are generally produced in the glue industry, which has a mild hazard to the body. However, with the increasingly perfect spray nonwoven processing technology, the industrial glue is slowly filtered out.
At this stage, the technology development of sprayed nonwoven manufacturing enterprises is better than the system software, such as hot air drying, baking forming, etc. Sprayed nonwoven viscose is more environmentally friendly and non-toxic. Some leading manufacturers of sprayed nonwoven production equipment in China are not the same, and even we can produce sprayed nonwoven without viscose. This kind of non-stick nonwoven is harmless to health.
What is the difference between spray nonwoven and non-bonded nonwoven?
Non-bonded nonwoven: Non-bonded nonwoven, also known as non-sprayed nonwoven, is generally softer than gushing, has excellent thermal properties, and is very washable. It can generally be used as a filler for various daily necessities. Spurs are generally used in heavy chain and high-speed railway organic chemical industries, air heaters, filtration devices, etc.
Sprayed nonwoven: Rubber sprayed nonwoven is made of high-performance, anti-fracture fiber filter device, and its structure is continuously improved (ie, organic chemical fibers whose fiber relative density is increased toward pure gas); rubber sprayed nonwoven is silicon-free and has low frictional resistance. , High exhaust air volume, high dust volume, the effect is very good;
Rubber sprayed nonwoven is heat-resistant (100℃≤); rubber sprayed nonwoven can be used for long-term cleaning; rubber sprayed nonwoven is suitable for general gas control units, air conditioning units, exhaust systems, air inlet pre-filter products, iron-making blast furnace air heaters , automotive ventilation rooms, industry, furniture manufacturing plants, paint spraying.
From the perspective of filtration technology performance, the actual effect of spraying nonwoven can be stronger, generally medium-efficiency filtration, and is often used to adjust and operate as a gas according to various areas with strong air index management requirements. The filter equipment of the information system; the actual effect of the filtration without colloidal nonwoven is slightly worse, which is the initial effect filtration, and is generally mainly used in the water filtration system of the fish tank.
