Nonwoven fabrics are broadly defined as sheet or web structures bonded together by entangling fiber or filaments (and by perforating films) mechanically, thermally, or chemically. They are flat, porous sheets that are made directly from separate fibers or from molten plastic or plastic film. They are not made by weaving or knitting and do not require converting the fibers to yarn.
How is Nonwoven Fabric used?
Beyond simple definitions, these engineered fabrics open up a world of innovative possibilities for all types of industries.
Nonwovens may be a limited-life, single-use fabric or a very durable fabric. Nonwoven fabrics provide specific functions such as absorbency, liquid repellency, resilience, stretch, softness, strength, flame retardancy, washability, cushioning, filtering, bacterial barriers and sterility. These properties are often combined to create fabrics suited for specific jobs while achieving a good balance between product use-life and cost. They can mimic the appearance, texture and strength of a woven fabric, and can be as bulky as the thickest paddings.
How are Non-Woven Polypropylene Bags Eco-Friendly?
Nonwoven polypropylene bags promote a greener earth because they are reusable, easy to clean, recyclable, and sometimes made with recycled products. These bags can be quickly wiped clean, and some of them are machine washable in cold water if they are drip dried. Most nonwoven polypropylene bags are also made of 5-type recyclable plastic. Reusing and recycling them could save many standard plastic bags from sitting in a landfill. After the non-woven polypropylene bags have been recycled, they may even be made into new totes.
