Problems solved by technology

[0003] The development of artificial grass fiber has gone through the development stages of the first generation of nylon, the second generation of polypropylene, and the third generation of polyethylene. The durability of nylon is relatively good, but its mechanical properties and dryness will occur after absorbing water. Changes, thereby changing the inherent characteristics of the lawn. Polypropylene has poor weather resistance and is prone to fibrillation, and its surface friction coefficient is large, which is easy to cause damage to athletes' sliding. Although the third-generation polyethylene is better than the previous generations The sports performance of artificial grass has been greatly improved, but for intense h

Abstract

The invention discloses an enhancing type artificial turf fibre and a preparing method thereof which belongs to the artificial turf technique field. Fibre intension and flexible of the enhancing type artificial turf fibre are increased greatly and is suitable for occasion with great intensity movement and vehement that can reduce probability of influencing movement caused by turf fibre hurting. The enhancing type artificial turf fibre is composed of matrix resin, enhancing master batch and functional material that each component has weight percentage as follows: 60-94% matrix resin, 5-30% enhancing master batch and 0.1-10% functional material.

Description

technical field [0001] The invention relates to a fiber and a preparation method thereof, more specifically to a reinforced artificial turf fiber and a preparation method thereof, and belongs to the technical field of artificial turf. Background technique [0002] Natural turf is the first choice for large-scale international competitions. It can meet the sports and protection functions, but it has the disadvantages of poor durability and weather resistance, high management costs, and it is not suitable for large crowds and high-density sports. Compared with natural turf, artificial turf has obvious advantages in addition to being close to natural turf in terms of performance: it can be used 24 hours a day, less affected by rain and snow, easy to maintain, and low maintenance costs. [0003] The development of artificial grass fiber has gone through the development stages of the first generation of nylon, the second generation of polypropylene, and the third generation of po...
