Abstract

The invention discloses an artificial turf with high tufting strength and a preparation process thereof. The artificial turf comprises artificial grass fibers and a base fabric, and the base fabric comprises a base fabric A and a mesh fabric in order from top to bottom. , Base fabric B, the artificial grass fiber is in a "U" shape, and the bottom of the "U" shape is located at the bottom of the base fabric A and the top of the mesh fabric. The present invention forms a three-layer composite base cloth by setting the structure, material and preparation process of the artificial turf, and places the bottom of the artificial grass fiber between the mesh cloth and the base cloth B, and when compounding, the low-melting mesh cloth melts, The base fabric A and base fabric B are bonded with artificial grass fibers to achieve a high single-tuft pull-out force of artificial turf, which is compatible with the existing artificial turf tufting process, no need to add new machines, reduces production processes, and improves Production efficiency and production cost reduction; mesh cloth is melt-blown to make mesh, and the artificial turf has better water permeability and better drainage effect.

Description

technical field [0001] The invention relates to the technical field, in particular to an artificial turf with high tuft strength and a preparation process thereof. Background technique [0002] Nowadays, the technical level and emphasis on science and technology and education are gradually increasing. As a substitute for natural turf, artificial turf has higher sports functionality and is widely used in sports and leisure places. Generally, artificial turf is composed of spread base cloth, The artificial grass fiber on it and the adhesive at the bottom of the base cloth are mostly made of polyethylene, polypropylene, polyethylene terephthalate, polyurethane, etc. After the artificial turf is used and reaches its service life, in order to maintain environmental friendliness, it is necessary to recycle the discarded artificial turf and realize waste utilization to avoid environmental pollution and waste of resources. And some existing artificial turf utilizes hot-melt adhesiv...
