Non-woven fabric (English name: Non Woven), also known as non-woven fabric, refers to non-woven fabric. It is a fabric that does not need to be spun and weaves. It is just oriented or randomly braided textile staple fibers or filaments to form The web structure is then reinforced by mechanical, thermal bonding or chemical methods.
Non-woven fabrics are mostly made of polypropylene (PP material) pellets, which are produced by high-temperature melting, spinning, laying, and hot-pressing and coiling in a continuous one-step process. It is called because of its appearance and certain properties. cloth.
The fibers used in the production of non-woven fabrics are mainly polypropylene (PP) and polyester (PET). In addition, there are nylon (PA), viscose fiber, acrylic fiber, polyethylene fiber (HDPE), and chlorine fiber (PVC).
Spunlace non-woven fabric is a non-woven fabric formed by directly using polymer chips, short fibers or filaments to form fibers through airflow or mechanically, and then through hydroentanglement reinforcement, and finally after finishing.
Spunlace non-woven: high-pressure fine water jets are sprayed onto one or more layers of fiber webs to entangle the fibers with each other, so that the fiber webs can be reinforced and have a certain strength.
Non-woven fabric is a new type of fiber product with soft, breathable and flat structure. The advantage is that it does not produce fiber debris, is strong, durable, and silky soft. It is also a kind of reinforcing material, and it has a cotton feel, compared with cotton fabrics. , Non-woven bags are easy to shape and cheap to make. The disadvantage of non-woven fabrics is that they have poor strength and durability and cannot be cleaned like other fabrics. Because the fibers are arranged in a certain direction, they are easy to split from the right-angle direction.
It is a new generation of environmentally friendly materials with the characteristics of water repellency, breathability, flexibility, non-combustibility, non-toxic and non-irritating, and rich colors. When burning, it is non-toxic, tasteless, and has no leftover substances, so it does not pollute the environment, so environmental protection comes from this. The chemical structure of polypropylene is not strong, and the molecular chain can be easily broken, which can be effectively degraded and enter the next environmental cycle in a non-toxic form.
