Non-woven fabric forming process

Recently, I often receive inquiries from customers about the process of our non-woven fabrics. Why are they called non-woven fabrics, but there are so many kinds. I don’t understand, I really don’t understand. Then I will introduce to you today, five The main non-woven fabric forming process, you can roughly understand why the needle punched non-woven fabric is not a waterproof non-woven fabric.


1. Needle-punched non-woven fabrics Needle-punched non-woven fabrics are a kind of dry-laid non-woven fabrics. Needle-punched non-woven fabrics are punctured by needles to reinforce the loose web into a fabric. The material is polyester fiber. Generally speaking, it is a kind of fiber cotton. Is it waterproof? Now I tell you clearly that needle-punched non-woven fabric is not waterproof, and its water absorption effect is also a major feature, and it has a great effect on moisturizing and water retention.


2. Stitched non-woven fabrics Stitched non-woven fabrics are a kind of dry-laid non-woven fabrics. Needle-punched non-woven fabrics are stitch-bonded using warp-knitted loop layouts for fiber webs, yarn layers, and non-woven materials. (For example, plastic sheet, plastic thin metal foil, etc.) or their combination stop reinforcement to make a non-woven fabric.


3. Spunlace non-woven fabric The spunlace process is to spray low-pressure fine water stream 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.


4. Thermally bonded non-woven fabric Needle-punched non-woven fabric Thermally bonded non-woven fabric refers to the addition of fibrous or powdery hot-melt bonding reinforcement materials in the fiber web, and the fiber web is heated, melted and cooled to form a cloth .


5. Spunbond meltblown non-woven fabric Spunbond non-woven fabric is formed after the polymer has been extruded and stretched to form continuous filaments, the filaments are laid into a net, and the fiber net is then bonded to itself. Thermal bonding, chemical bonding or machine reinforcement methods make the web into a non-woven fabric.
