There are also paper or non-woven fabrics impregnated with adhesive, adhesive coated on the surface, mixed paper types made of a small amount of synthetic fibers, and paper or non-woven fabrics coated with a film. There are nine types of laminated paper.

。Furthermore, a synthetic paper for tea packs made of polyester fibers as a main component and heat-fusible fibers and cellulose fibers as Prene P is disclosed in JP-A-60-14830.
テイーパツク用フィルターは、接着することが必須であ
るが、前記したように従来のものには、接着剤熱融着性
繊維、熱融着性フィルムが用いられている。It is essential for filters for tea packs to be adhesively bonded, and as mentioned above, conventional filters use adhesives, heat-fusible fibers, and heat-fusible films.

気性、通販性を悪くしている。However, these conventional adhesives occupy a large area of the filter after hot-melting, adhering, or spraying, resulting in poor air permeability and mailability, which are the performance required for tea bank filters. There is.
本発明者等は、このような問題な解決すべく鋭意研究を
進めた結果、従来全く考えられなかった微粒子状の熱融
着合成高分子を用いることを発想し、本発明をなすに至
った。As a result of intensive research aimed at solving these problems, the present inventors came up with the idea of using heat-fused synthetic polymers in the form of fine particles, which had never been thought of before, and came up with the present invention. .
〈発明の構成）
このような本発明の目的を達成するための本発明の要旨
は、紙或は不織布を微粒子状の熱融着合成高分子で分散
融着させてなることを特徴とするテイーパツク用フィル
ターにある。(Structure of the Invention) The gist of the present invention for achieving the object of the present invention is to provide a tea pack characterized in that paper or nonwoven fabric is dispersed and fused with fine particle-shaped heat-fusible synthetic polymers. It is in the filter for.
本発明は従来のテイーパツク用素材にすべて適用できる
。木材パルプから抄紙した紙、或は和紙、さらには合成
紙に適用できる。ま之セルロース繊維系の不織布に適用
できる。The present invention can be applied to all conventional tea pack materials. It can be applied to paper made from wood pulp, Japanese paper, and even synthetic paper. It can be applied to cellulose fiber-based nonwoven fabrics.
特に、セルロース繊維系の不織布の場合は、−般の紙と
は異なり、空隙部分がある。そのためフィルム状熱融着
剤では内部ｉで効率よく接着することがむずかしかった
。しかし、不発明の微粒子の熱融着剤により内部も容易
にかつ効率よく接着で應るので、より好ましい。In particular, cellulose fiber-based nonwoven fabrics have voids, unlike ordinary paper. Therefore, it has been difficult to efficiently bond the interior i with a film-like heat fusion adhesive. However, it is more preferable because the inside can be easily and efficiently bonded using the uninvented fine particle thermal adhesive.

く、５００μｍ以上では熱融着囲槓が広くなり通気性、
通液性の悪いものとなる。The particulate heat-sealable synthetic polymer used in the present invention includes:
There are polyethylene, polyester, polypropylene, etc. Polyethylene is preferred because of its waiting ζ fusion temperature. The size of the fine particles is 50-500μ, preferably 100-6
A material with a diameter of 0 μm is used. If it is less than 50 μm, it will easily leak from the fiber gaps of the material during the manufacture of filters for tea packs, and if it is more than 500 μm, the heat-sealed area will become wider, improving breathability.
This results in poor liquid permeability.
また紙或は不織布に分散する微粒子の量は、微粒子の大
きさを考慮して選ばれるが、上記の太ささの微粒子を用
いる場合６〜１２Ｎ／ｍ”の量が適当である。The amount of fine particles to be dispersed in the paper or nonwoven fabric is selected taking into consideration the size of the fine particles, but when using fine particles of the above-mentioned thickness, an amount of 6 to 12 N/m'' is appropriate.

This is a reproduction of an enlarged photograph.

フィルターを提供することができるのである。In the figure, 3 is a nonwoven fabric made of regenerated cellulose fibers, 4 is polyethylene fine particles fused onto this nonwoven fabric, and 5 is a fused heat-sealable fiber. As shown in FIG. 2, the intervals between the fine particles are wide, and this becomes clear when compared with FIG. 6. As shown in the figure, the fibers mixed with heat-fusible fibers have a large fused area, resulting in poor air permeability and poor liquid permeability. If the amount of mixed iron is reduced in an attempt to improve this, the heat-sealed portion will be insufficient when processed into a tea pack. On the other hand, in the case of the present invention shown in FIG. 2, the spacing between the fused fine particles can be relatively wide, and moreover, the heat fused portion can be made sufficient during the taping process. Therefore, it is possible to provide a tea bank filter with excellent air permeability and liquid permeability.

Therefore, a high-quality tea pack can be obtained, and when used in the tea pack, it is possible to provide a tea bank that has a good tea aroma and a good tea flow, and has the performance that has been conventionally desired for treating itchy skin.
