Method for manufacturing artificial turf

Abstract

Provided is a method for manufacturing an artificial turf, including: providing a base cloth; providing artificial turf yarns; tufting the artificial turf yarns on the base cloth, and applying an adhesive; and blowing air to the base cloth having the adhesive applied thereto to obtain the artificial turf. According to the manufactured artificial turf, when passing air through the air blowing device, water permeable holes are formed in the bonding layer applied on the base cloth. The water seepage rate of the artificial turf is increased by means of water seepage through the water permeable holes. Moreover, there is no need to pierce the adhesive applied surface of the base cloth during production, thereby avoiding damage to the structure of the artificial turf by piercing. This effectively prevents the artificial turf yarns from loosening and falling off and prolongs the service life of the artificial turf.
