PA/PET sheath core type thermal bonding spunbonded nonwoven fabric

Colbond produces high-performance two-component composite spunbonded nonwovens with PA as the skin layer and PET as the core layer. The single-filament fineness is 10d or 15d, mainly 15d, and the trade name is Colback. Of course, CoPET can also be used as the skin material. However, in most cases, polyester PET is used as the core layer, and nylon PA is the skin layer.
Polyester PET as the core layer can ensure good high temperature and mechanical stability. As a skin layer, nylon PA has good adhesion to a variety of coating fabrics and dyes. The thermally bonded filaments are bonded at the intersections under temperature and pressure without the use of any chemical binder.
The product has good surface uniformity, high strength, the same longitudinal and transverse properties, stable size, strong affinity with coating materials, good asphalt adhesion, no chemical adhesive, moldable, foldable , can be formed, can be dyed, can be welded, easy to compound. Widely used in flooring materials, automotive industry and construction engineering. It is believed that Colback products are a reliable and cost-effective product for advanced end products. Colback is widely used in advanced (printed and tufted) wide rugs, carpet backings, and backing mats for dusting mats. Product size and thermal stability prevent handling and bending and misalignment during installation. In the flooring material, Colbond mainly uses PET as the core layer and PA as the skin layer. Used for dust control mats, the main fiber has a fineness of 10d and the color is mostly black. In terms of decorative materials, it can be used for the separation layer and the support layer of the filter, mainly using 15d fibers, and the color is mostly white. Due to its high elongation properties, Colback can be used in the automotive industry. Colback is used as the back material for molded carpets, and is also used in automotive interiors such as hood mats, body panels, door panels, and saddles. Colback has a composite property with glass materials and can be applied to roof systems in construction engineering. In addition, Colbond also produces PET/PP two-component sheath-core composite thermal bonded spunbond fabric under the trade name Colback. It can be used to produce automotive molded carpets. The products have good dimensional stability and excellent molding effect. The molding temperature is low, which can reduce the production cost of downstream processing.
