what is the main material and characteristics for themral bond nonwoven
Thermal bond is the last line into the net in the process of non-woven fabric production technology, is a process cooling spread achievements after silk fabrics, thermal bond is a high temperature (100 ~ 150 degrees, rolling wheel uniform filaments makes melt and into the net, so there will be rolling point on thermal bond nonwoven, like pinhole, but does not penetrate, the specific size depends on the size of the rolling wheel steel thorn and density. So it is not difficult to draw, as a kind of craft, thermal bond nonwoven is not a specific one cloth, but a kind of through a similar process into the floorboard of the non-woven fabric, generally speaking, the use of thermal bond process is a method of spun-bonded polypropylene non-woven fabric (PP., polyester fiber non-woven (PET., PA polyamide (PA), the three biggest different is the processing of raw materials.
The main material
(1) natural fibers: cotton, wool, hemp and silk;
(2) conventional fiber: viscose fiber, polyester fiber, acetate fiber, polypropylene fiber, polyamide fiber;
(3) differentiated fibers: ultrafine fiber, shaped fiber, low melting point fiber, high curly fiber, antistatic fiber;
(4) high functional fiber: aromatic polyamide fiber, carbon fiber, metal fiber.
Non-woven fabrics can have many characteristics and distinguish properties such as non-entangled edges and unique fiber orientation in the fabric.
They can be soft or hard, strong or weak, directional and omnidirectional in performance, have one or both smooth or uneven sides, provide bulk or very compact, two or three dimensions, solid or patterned openings, absorbent or repulsion and porous puncture.
Many of these functions can be combined in a receipt to satisfy an end-use product. Nonwoven fabrics can be elongated, stretched and restored at specific apertures, but cannot be brushed, which is a very important difference between nonwoven and textile fabrics
In addition, they can provide a good substrate for coating, composite material, lamination, printing, embossing and forming, reason often used in packaging materials, relatively non-woven fabric as a packaging material cost is more expensive than regular packing carton, that's why has not been widely used, non-woven fabric manufacturer if you want to fully open the big market, reduce the cost and go for the green line is the biggest challenge.
