The invention pertains generally to a low-pressure (100-250 psi) process of seaming adjacent seams of artificial turf using a one-component or a two-component polyurethane adhesive using an apparatus which employs a payoff spool of base material in the front of the apparatus and an activation trigger adjacent the handle to begin the application of polyurethane spray foam adhesive by connectivity between the application trigger and the foam spray gun trigger.

The invention provides for a method of delaying and reducing texture reversion of a textured artificial turf yarn (145), characterized by using a stretched and textured monofilament yarn as the textured artificial turf yarn, the stretched and textured monofilament yarn comprising a polymer mixture (400, 500), wherein the polymer mixture is at least a three-phase system, wherein the polymer mixture comprises a first polymer (402), a second polymer (404), and a compatibilizer (406), wherein the first polymer and the second polymer are immiscible, wherein the first polymer forms polymer beads (408) surrounded by the compatibilizer within the second polymer.

A method for manufacturing a synthetic non-perforated drainable material is disclosed herein. Generally, the method includes injecting a coating material with air, applying the air-injected coating material to the first side of the material, and curing the air-injected material such that it adheres. Once cured, the material has a highly efficient drainage rate that remains consistent throughout the life of the material.

Compositions and methods in which aragonite, and especially oolitic aragonite particles are used as infill material in an artificial turf structure or as sub-growth substrate for natural grass. Advantageously, oolitic aragonite particles provide a superior microporous surface for effective water saturation to impart thermal control and environmental compatibility, ammonia neutralization of urine by reducing urea hydrolysis with the free calcium presented in the aragonite particles, aragonite particle uniformity allowing for reduced compaction and desirable water draining, and the microporous oolitic aragonite particles have an evaporative cooling surface.

An artificial turf contains a damping layer made of a particle foam, a fiber backing, and an artificial grass layer made of single or multiple fibers. The fibers are tied to the fiber backing, forming an artificial carpet of grass. The particle foam and the single or multiple fibers forming the artificial grass layer are each made of a thermoplastic elastomer.

An artificial turf can include a base material; a plurality of piles imitating turf leaves erected on the base material; and a filler layer formed by a filler material being filled between the plurality of piles, wherein the filler layer includes a water retaining layer and a mineral having calcium carbonate as a major component.
