てきた。2. Description of the Related Art An artificial turf is generally formed by piercing (puffing) a pile thread made of a thermoplastic resin into a woven cloth made of a polypropylene fiber or the like referred to as a primary base cloth (tufting), and cutting the top of the pile looped. It is manufactured by applying a latex material to the back surface and fixing pile yarn to the primary base fabric.Conventionally, the yarn used for this type of artificial grass pile is made of poly. Synthetic fibers composed of vinylidene chloride, polypropylene or polyamide resin have been widely used.

点があった。[0003] Among them, the yarn made of polyvinylidene chloride has a problem that toxic gas is generated at the time of incineration after use, and the yarn made of polypropylene has a disadvantage that it is inferior in weather resistance and set resistance. On the other hand, the yarn made of polyamide resin is superior in compression recovery force, abrasion resistance, sag resistance, texture and the like, and is frequently used as an artificial turf pile for many applications. However, polyamide resin lacks flexibility and the pile tends to be too upright.When used as artificial turf containing sand, the sand filled in the gap between the piles is scattered, moved, ubiquitous and hardened each time it is used. When tufting a polyamide resin yarn in the manufacturing process of artificial turf, there were problems such as poor flexibility and poor tufting efficiency due to the strong rigidity of the yarn. .

工芝パイル用糸条は、いまだ見いだされていなかった。[0004] In order to supplement the flexibility and the like of the polyamide resin, a method of mixing nylon fibers and polypropylene fibers and planting them as artificial turf (Japanese Patent Laid-Open No. Hei 4-37923). A method of twisting and flocking (Japanese Patent Laid-Open No. 7-48778) and the like have been proposed. However, in the method of mixing or twisting a polyamide fiber and a polyethylene fiber or a polypropylene fiber, although the apparent flexibility is improved, the flexibility of the polyamide fiber itself is not improved, and the tufting efficiency in the tufting process is reduced. The problem of inferiority has not been solved, and an artificial turf pile yarn made of polyamide fiber having excellent flexibility has not yet been found.

にあるが、柔軟性、加工性等は低下する傾向にある。The following can be understood from these results. Generally, in a polyamide resin composition obtained by melt-kneading a polyamide resin and a polyethylene resin composition, both components are incompatible, and a uniform crystal structure cannot be obtained due to a difference in crystallinity. However, in the present invention, the sea-island structure of both components formed from a composition having a specific compounding ratio has an effect of imparting flexibility because of having an appropriate stress absorbing effect between the phases, and It is thought that the purpose of this can be achieved. When a part of the polyethylene-based resin composition contains a polyethylene-based resin graft-modified with maleic anhydride, the incompatibility of both components is improved, and the mechanical strength such as tensile strength is increased. Although there is a tendency, flexibility, processability, and the like tend to decrease.

的に使用される。The yarn for artificial turf pile of the present invention is a yarn formed from a polyamide resin composition comprising a polyamide resin and a specific polyethylene resin composition, and has a compressive recovery force, abrasion resistance, It is excellent in impact resistance, workability, and flexibility, and is extremely effective for artificial turf piles. The artificial turf obtained from this artificial turf pile yarn is used in baseball fields, golf courses, and soccer fields. It is used for various purposes, such as playing fields, athletic facilities such as tennis courts, greening parks and gardens, terraces and verandas of various buildings, and decorative uses for exhibitions.
