Yuzhimu nonwoven backing and carpet

Over the years, Yuzhimu nonwoven primary carpet backings have been constantly improved in order to meet the ever more stringent demands of carpet manufacturers and consumers. Of particular importance are: increasing the breaking strength and elongation at break after tufting, increasing the tear resistance after tufting and coating, generally improving the appearance of the resulting carpet, allowing effective mending of imperfections that occur during tufting, and facilitating tuft ability, i.e. by providing lower tuft-needle penetration resistance and reduced needle deflection during tufting, avoiding rough back stitch, increasing stitch lock, and reducing noise during tufting.

A primary carpet backing is required to be as thin as possible, compatible with acceptable tear strength and dimensional stability (which properties should be maintained after tufting, dyeing and application of a secondary backing), since the properties of a tufted carpet depend at least in part on the quantity of service pile. Pile which is inaccessible for use by virtue of being buried in the carpet backing represents a loss of otherwise useful pile yarn to the carpet manufacture. The primary carpet backing should further be composed of a material which does not stain the pile of the carpet when wet. It should also preferably be capable of being dyed in the same dye bath as that in which the pile is dyed without the necessity of making special provisions in order to reduce "grin through." Again, it should largely retain its tear strength after tufting and also it should be compatible with an adhesive for a secondary backing such as latex.
