ニスボールは従来に無い新規のものである。 As mentioned above, although FIG. 2 is a schematic explanation of a single pile fiber, it should be noted that in reality, countless piles 5 are laminated to cover the surface of the skin 4. Should. In this way, the tennis ball using the high pile circular knitted fabric 4 in which the low-height loop piles 5a, 5c and the relatively short piles 5e having free ends are mixed in a predetermined ratio is a new and unprecedented one. It is.
本発明者の研究によれば、このような表皮を製

好ましく、特に65重量％：35重量％の比率が最
も好ましい。1. The sliver used to form the pile fiber is preferably a blend of wool fiber and nylon fiber in a ratio of 80 to 60% by weight: 20 to 40% by weight, particularly 65% by weight: 35% by weight. The most preferred ratio is
２ ニードルパンチング前のパイル５の長さは、
２〜６cmの範囲が望ましい。２cm未満の場合に

と、表皮４全体の厚さと重量が必要以上に増加
するので好ましくない。2. The length of pile 5 before needle punching is
A range of 2 to 6 cm is desirable. If it is less than 2 cm, it is difficult to form two or more anchor portions 5b, 5d that reach the back side of the fabric, and the pile tends to fall off, which is not preferable. Furthermore, since the number of loop-shaped piles 5a, 5c is reduced, elasticity tends to be insufficient. On the other hand, if it exceeds 6 cm, the thickness and weight of the entire skin 4 will increase more than necessary, which is not preferable.
３ 投錨部５ｂ，５ｄの突出長さは1.5〜2.5mmの
範囲が望ましい。1.5mm未満の場合にはパイル
の投錨力が不足して抜け易く、一方、2.5mmを
越える場合には表皮４全体の厚さが増加し過ぎ
て好ましくない。3. The protruding length of the anchoring parts 5b and 5d is preferably in the range of 1.5 to 2.5 mm. If it is less than 1.5 mm, the anchoring force of the pile will be insufficient and it will easily come off, while if it exceeds 2.5 mm, the thickness of the entire skin 4 will increase too much, which is not preferable.
４ パイル繊維は実質的に生地の全面を被覆可能
な程度の密度で編み込まれることが望ましい。4. It is desirable that the pile fibers be knitted at a density that allows them to cover substantially the entire surface of the fabric.

表面に突出しているので、その効果は大きい。 The skin based on the circular high pile fabric used in the present invention has multiple layers of pile fibers that substantially completely cover the entire surface of the fabric, and in particular, there are many piles 5e with free ends. It is distinctive in that it does so. This is a significant difference from conventional raised felt fabrics, and the free end pile 5e acts like a spring, helping to impart appropriate elasticity to the tennis ball. Moreover,
Since the maximum angle θ formed by the free end pile 5e protrudes from the surface and exhibits various different values within the range from 0° to 90°, the effect is great.

The tennis ball of the present invention has excellent flexibility and elasticity due to the synergistic effect of the spring action of e and the covering action of the multilayered ruby piles 5a and 5c. Moreover, each pile fiber 5 has at least two anchoring parts 5b and 5d that reach the back side of the ground structure by needle punching, and since adjacent piles overlap each other, shedding is prevented and the life is long. Become. Furthermore, the weight can be reduced by appropriately selecting the type of fiber used for the skin.

This sliver was knitted while the ground structure of the plain knit structure was knitted with 30 count polyester spun yarn on a high-bal knitting machine to obtain a circular knit high pile fabric having a pile of 5 cm in length. After cutting this fabric, a shearing process is performed to make the pile height uniform, and the surface is brushed to ensure that the pile fibers on the surface touch the ground texture.
They were aligned in a certain direction so that they would sleep at an inclination of about 5°.
Next, the circular knit high pile fabric was punched about 200 times/cm 2 from the pile side so that the anchor part protruded about 2 mm from the back side of the ground structure.
Next, this fabric was subjected to a known wool-type crimp process to thoroughly intertwine the wool fibers that make up the pile, and then finished and dried to form a product.
