Artificial turf grass with natural appearance

a natural appearance, artificial turf technology, applied in the field of fibers, can solve the problems of affecting the appearance of artificial turf, affecting the durability of the material, and achieving melt fractures at the expense of draw ratio flexibility or even durability compromise, so as to improve the uv resistance of the yarn, maintain the mechanical strength of the base polymer, and improve the appearance of the yarn

AI Technical Summary

Benefits of technology

The patent describes a type of yarn that is made with special particles made from acrylic. When these particles are added to the yarn, it looks and feels more like natural grass. The added particles also improve the strength and durability of the yarn. Additionally, the acrylic particles help protect the yarn from UV damage. This patent explains the technical effects of this special yarn and how it can be used in various applications.

Problems solved by technology

While use of such polymers is helpful for cost and durability it can lead to an appearance that is not looks synthetic.
However, melt fracture is typically achieved at the expense of draw ratio flexibility or even durability compromise.

Formulating the Composition

[0078]Materials used:[0079]DOWLEX™ 2107GC LLDPE resin, Density=0.917 g / cm3, melt index=2.3 g / 10 min (190° C., 2.16 kg).[0080]PARALOID™ EXL-5136 core / shell polymer in powder form.[0081]FUSABOND™ E265 as compatibilizer. This component is a HDPE grafted with maleic anhydride. Density is 0.950 g / cm3 and melt index=12 g / 10 min (190° C., 2.16 kg).[0082]Sicolen green 85-125345, from BASF, was used as color masterbatch.

[0083]The materials were combined according to the and melt blended on a Buss Kneader Compounder as 120 rpm kneader speed and extruded at 8 kg / hr at temperature profile of 110 / 130 / 140 / 120 / 125° C. The following table 1 summarizes the formulations of the different films, together with the fabrication conditions. All blends were melt-blended prior to extrusion on a Buss Kneader Compounder at 120 rpm (kneader speed), 3 A (motor current), 8 kg / h, 60 rpm (screw speed) and a 110 / 130 / 140 / 120 / 125° C. temperature profile. The formulation as set forth in Table...

Abstract

Disclosed herein is a turf filament comprising from 50 to 99.5 weight percent of abase polymer selected from polyolefins, polyamides, polyesters and combinations thereof, from 0.1 to 20 weight percent of polymer particles having a core and a shell structure where the core comprises a first polymeric material having a first refractive index and the shell comprises a second polymeric material having a second refractive index that is different from the first refractive index, from 0.5 to 30 weight percent of a compatibilizer and from 0 to 10 weight percent of a colorant based on total weight of the filaments. Also disclosed is a synthetic turf comprising such filaments. These filaments provide a turf with a natural appearance.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of European Application No. 19382003.2, filed on Jan. 3, 2019, which is incorporated herein by reference in its entiretyFIELD OF THE INVENTION[0002]The field of this invention is fibers for use in artificial turf and artificial turf having such fibers.BACKGROUND[0003]Artificial turf is often used to provide ground coverings for sports facilities, such as football or soccer fields, and sometimes for decorative use. A common structure for this artificial turf, particularly for sports fields, includes a sheet-like substrate with a plurality of filiform formations or fibers (i.e., synthetic grass blades or turf yarn or turf filaments) extending from the substrate for simulating the grassy sward of natural turf and a particulate filling material, or infill, dispersed between the filiform formations so as to keep the filiform formations themselves in a substantially upright condition.[0004]The synthetic grass...
