Problems solved by technology

There are two major defects in existing chemical fiber products. One is that the service life is short, generally only about three years, and there is no outdoor application product in China; the other is that the performance of rolling balls on existing alternative products is unstable.

Embodiment Construction

[0012] Existing pétanque flooring products are needle punched from polypropylene and polyamide fibres. The above-mentioned existing products are analyzed, researched and tested, and the reason for their short life is that polypropylene fiber itself has poor UV resistance and is easy to weather, and is affected by temperature in summer and winter, and is prone to excessive expansion and contraction, and poor stability; nylon fiber is affected by Influenced by humidity, uneven dry and wet shrinkage, not resistant to mildew, prone to insects, particularly strict requirements on humidity, in addition, the structure of the above-mentioned products has unstable stiffness due to the absence of connecting substances between fibers, so the rolling ball on the blanket Running speed is unstable. After testing, a base fabric is added in the fiber needle-punched blanket, so that the fiber layers on the upper and lower sides of the base fabric can be combined with the base fabric more firml...

Abstract

The invention discloses a fiber needled blanket for a boccia court. The blanket comprises two fiber needled layers, wherein a base fabric layer is arranged between the two fiber needled layers; the fibers of the two fiber needled layers are two kinds of blend fibers with different fineness; the fineness of one kind of fibers is 81-90 deniers; the fineness of the other kind of fibers is 21-30 deniers; the fibers with fineness being 81-90 deniers account for 60-80wt% of the blend fibers; the balance is the fibers with fineness being 21-30 deniers; and the two kinds of blend fibers with different fineness are polyester staple fibers. Compared with the prior art, the fiber needled blanket has the obvious advantages of long life and stable movement performance of the boccia.

Description

Technical field: [0001] The invention relates to a blanket for sports fields, in particular to a fiber needle-punched blanket for a pétanque field. Background technique: [0002] The bowling court was originally a grass field (similar to a golf course). In recent years, based on the need for environmental protection and reducing construction and maintenance costs, the natural lawn of the bowling court has gradually been replaced by artificial grass, that is, chemical fiber products. There are two major defects in existing chemical fiber products. One is that the service life is short, generally only about three years, and there is no outdoor application product in China; the other is that the performance of rolling balls on existing alternative products is unstable. Invention content: [0003] The purpose of the present invention is to provide a fiber needle-punched blanket for a bowling court with long service life and stable rolling performance. The pricking layer is tw...
