Man-made lawn and preparation method therefor

Abstract

The invention relates to a preparation method for a man-made lawn. The preparation method comprises the following steps: arranging warp yarns on a warp beam of a braiding machine, arranging weft yarns on the braiding machine in a direction perpendicular to the warp yarns, arranging man-made grass silk yarns on a yarn creel at the back part of the braiding machine, enabling the man-made grass silk yarns to participate in braiding of bottom cloth in a direction parallel to the warp yarns, and performing grass jacquard weaving treatment on the man-made grass silk yarns by utilizing jacquard equipment of the braiding machine; bypassing the bottom cloth for 2-10 circles by each man-made grass silk yarn to form a cluster of grass silk, setting the height of the grass silk cluster to be 10-70mm, and arranging 6-12 warp yarns between any two adjacent grass silk clusters; and arranging 3-8 weft yarns between any two adjacent grass silk clusters in the grass silk clusters arranged vertically. The preparation method is simple, easy to operate and convenient for industrial production, and pullout force of the grass silk can be increased; and the man-made lawn prepared with the method has the advantages of environmental protection, wide application range and high stability.

Description

technical field [0001] The invention relates to the field of artificial turf, in particular to an artificial turf and a preparation method thereof. Background technique [0002] The structure of traditional tufted artificial turf mainly includes three parts: base fabric, grass fiber and adhesive. Generally, it is produced by tufting machinery. The grass fiber is tufted on the base fabric, then coated with adhesive, and dried in an oven. . Artificial turf can be used in sports fields such as football and hockey, and can also be used in leisure fields such as gardens, kindergartens, and decorations. It belongs to a sunrise industry that is in a period of vigorous development. However, in the production process of tufted artificial turf, it is necessary to prefabricate the base fabric first, and then needle the grass filaments on the base fabric. The pull-out force of the grass filaments is extremely low. Benzene latex or two-component polyurethane latex binds the grass silk....

AI Technical Summary

Problems solved by technology

However, in the production process of tufted artificial turf, it is necessary to prefabricate the base fabric first, and then needle the grass filaments on the base fabric. The pull-out force of the grass filaments is extremely low. Benzene latex or two-component polyurethane latex binds the grass silk. The adhesive has no thermoplastic function and will further age and harden as the service life increases. As a result, the lawn cannot be recycled as a whole after the service life is reached, resulting in waste of resources and environmental pollution.
