Description
本発明は、繊維製生地の吸水性試験方法及びその装置に関する。 The present invention relates to a water absorption test method for a textile fabric and an apparatus thereof.
従来から、繊維製生地の水分ふき取り評価方法（吸水性試験方法）として、ＪＩＳ Ｌ １９０７に規定されているラローズ法が一般的に使用されている。このラローズ法は、直径６０ｍｍの繊維製試料を試料ホルダー４８０ｇの下に置き、その下にポリエチレンテレフタレート製のドーナツ板を介してガラスろ過板が配置されている。ドーナツ板の中央には内径２０ｍｍの孔が開いている。ガラスろ過板の下には水が入れられており、水はガラスろ過板を通過して繊維製試料内に吸収され、拡散される。この時の吸水量を時間経過で測定し、最大吸収速度、最大吸収速度時点の吸水量、吸水指数を算出することができる。
他の吸水性試験方法として、特許文献１にはプラスチック板上に水を滴下し、その上から試料を載せ、荷重をかけて吸水させ、試料を取り除き、プラスチック板上の残水量を測定し、その後吸水させた試料を濾紙の上に載せ、荷重をかけ、放置後試料の重量を求めて濡れ戻り率を測定することが提案されている。特許文献２には試料を蒸留水に浸漬した後に濡れ戻り率を測定することが提案されている。特許文献３にはアクリル板上に１ｃｃの水を水玉上に載せ、試料を載せ、濾紙を載せて濡れ戻り率を測定することが記載されている。
Conventionally, the Larose method specified in JIS L 1907 has been generally used as a method for evaluating moisture wiping of a fiber fabric (water absorption test method). In this Larose method, a fiber sample having a diameter of 60 mm is placed under a sample holder of 480 g, and a glass filter plate is placed under the sample holder via a donut plate made of polyethylene terephthalate. There is a hole with an inner diameter of 20 mm in the center of the donut plate. Water is placed under the glass filter plate, and the water passes through the glass filter plate, is absorbed into the fiber sample, and is diffused. The amount of water absorption at this time can be measured over time, and the maximum absorption rate, the amount of water absorption at the time of the maximum absorption rate, and the water absorption index can be calculated.
As another water absorption test method, in
しかし、前記ラローズ法及び各特許文献に記載されている濡れ戻り率は、タオルなどの繊維製生地の使用時に、人が感じる吸水性の良し悪しの評価と一致しないことがあるという問題があった。 However, there is a problem that the rewetting rate described in the Larose method and each patent document may not match the evaluation of the quality of water absorption that a person feels when using a textile fabric such as a towel. ..

A water absorption test was performed using a 100% cotton ring spun yarn and a towel (grain 323 g / m 2 , pile length 1.18 cm) of the woven fabric shown in FIGS. 4 and 5, and the water was reweaked. The rate was calculated. In addition, the feeling of rewetting felt when wiping the water adhering to the body with this towel was examined by a sensory test.
（実施例５）
コットン１００％のリング紡績糸を使用し、図４及び図５に示す織物生地のタオル（目付２６９ｇ／ｍ2、パイル長さ０．６９ｃｍ）を使用して吸水性試験を行い、水の濡れ戻り率を算出した。また、このタオルを用いて身体に付着した水分を拭いた際に感じる濡れ戻り感を官能検査により調べた。
以上の結果を表１にまとめて示す。
(Example 5)
A water absorption test was performed using a 100% cotton ring spun yarn and a towel (grain 269 g / m 2 , pile length 0.69 cm) of the woven fabric shown in FIGS. 4 and 5, and the water was rehydrated. The rate was calculated. In addition, the feeling of rewetting felt when wiping the water adhering to the body with this towel was examined by a sensory test.
The above results are summarized in Table 1.
以上の結果から、濡れ戻り率と官能評価には相関があり、タオル使用時に人が感じる吸水性の良し悪しの評価と合致することが確認できた。また、測定操作が簡潔であり、かつ複雑な操作を伴わないことから正確な測定ができることも確認できた。 From the above results, it was confirmed that there is a correlation between the rewetting rate and the sensory evaluation, which matches the evaluation of the quality of water absorption that a person feels when using a towel. It was also confirmed that the measurement operation is simple and does not involve complicated operations, so that accurate measurement can be performed.
本発明の吸水性試験方法は、バスタオル、フェイスタオル、タオルハンカチ、スポーツタオル、バスローブ、タオルケットなどのタオル生地、ハンカチ、手ぬぐい、布巾などの繊維製生地にも適用できる。 The water absorption test method of the present invention can also be applied to towel fabrics such as bath towels, face towels, towel handkerchiefs, sports towels, bathrobes and towelettes, and textile fabrics such as handkerchiefs, washcloths and cloths.
