Non-woven fabric is a very good, and degradable environmental protection packaging materials, is widely used in our life and industry, and if the use of pure non-woven products is limited, if you can make waterproof non-woven fabric, the market will be greatly increased, so what is the principle of non-woven fabric waterproof function?
In fact, strictly speaking, it is unrealistic to make non-woven fabric with waterproof function, in the process of manufacturing is impossible to achieve, because the material of non-woven fabric is generally cloth waste and other products, belongs to the category of cloth, itself does not have waterproof effect, so, the need for later processing in order to develop into waterproof non-woven products with waterproof effect. Generally speaking, so that it has waterproof function, to be fused with plastic, and currently we use the process is generally film or film coating process, in non-woven products, the use of film technology will melt plastic raw materials with non-woven adhesion, this way, not only enhance the service life of non-woven fabric, but also make it with waterproof function, Produced a new product a waterproof non-woven fabric, we also call it coated non-woven fabric.
Light weight, good strength, good waterproof performance, strong compatibility, and pigment ink with UV resistance, can be used outdoors, indoor short term without coating film, pearl canvas material feel soft, feel like natural silk. Its ink absorption and color performance is soft, no reflection, good waterproof performance. Used for indoor photo machine, water-based ink, the use of pigment ink suitable for long-term preservation.
