Non-woven filter cotton adopts polyester fiber material support, referred to as non-woven, non-woven fabric has the use of technology mature, good stability and other technical characteristics, is our country at the early stage, and middle effect plate type, bag type filter typical filter material. The non-woven fabric is made by several processes, such as melt-blasting, needling, spining and spinning. Compared with other filter materials of the same grade, it has the advantages of stable quality, large dust capacity, strong moisture resistance, long service life, economic and durable. Non-woven fabric is also the earliest application of filter materials, technology development is mature, low production cost, in recent years due to the continuous progress of technology, composite non-woven cotton appeared to improve the cheap and low-grade image of non-woven fabric, in the efficiency has been able to achieve sub-high efficiency. At the same time, the composite non-woven filter material can also be used for air cleanliness is relatively high in the place of filtration.
Non-woven filter cotton is made of 100% pure fiber by needling method to form a highly fluffy, three-dimensional depth filter layer. It is characterized by loose fiber tissue, high porosity increases the amount of impurities. It is a compound interception mode, which can effectively clean solid and soft particles. Large particles are intercepted on the surface of the fiber, and fine particles are captured in the deep layer of the filter material, so it has a high filtration efficiency.
Non-woven filter cotton material including polyester and polypropylene, mainly used for liquid filtration, accuracy between 1-200 microns.
