Nonwoven fabrics are broadly defined as entangled fibers or filaments (and filming machinery, thermal or chemical) bonded together in a table or web structure. They are flat, perforated plates, either directly from individual fibers or from a molten plastic or plastic film. They are all made of woven or knitted yarns that do not need to be converted. Usually, a certain proportion of recycled and oil-based materials are in nonwoven filter cloths. Percent recovery varies depending on the specific needs of the material strength used. In contrast, some nonwoven filter cloths can be recycled and given to appropriate treatment facilities. For this reason, some people think that non-woven fabrics are more important for certain applications of ecological fabrics, especially in the fields and industries where disposable or single-use products are important, such as schools, hospitals, nursing homes and luxury accommodation.
Nonwoven fabric cloth may be a limited life, disposable fabric or a very durable fabric. Nonwoven fabrics provide specific functions such as absorption, liquid resistance, elasticity, stretch, softness, strength, flame retardance, washability, buffering, filtration, use as a bacterial barrier and infertility. These characteristics are often combined with the creation of a fabric that fits a specific job, while achieving a balance between the product's lifespan and cost. They can imitate the appearance, structure and strength of the woven fabrics as bulky thick pads. In combination with other materials they provide a wide range of products with different properties, used alone or as part of clothing, household items, health care, engineering, industrial and consumer goods.
