DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bath towel excellent in massage effect and dirt removal.

[0002]

2. Description of the Related Art Conventionally, paper has been widely used as oil removing paper for cosmetics because of its excellent water absorbing property and oil absorbing property. Also, paper is cut into a tape and twisted to form a paper thread. Woven and knitted fabrics made from this paper thread are used for clothing and living materials. It has also been proposed to use as a bath towel. And the bath towel made of this paper thread is water absorbing,
It is characterized by being excellent in sebum adsorption, foaming, foam removal, etc., and also gentle on the skin and excellent in the massage effect on the skin. However, there is a problem that the paper easily breaks because the strength tends to decrease when wet, and the drying speed is slow. When the thickness of the paper thread is increased in order to improve the problem of the decrease in wet strength among these, another problem occurs in that the ability to wipe off dirt attached to the skin is reduced.

On the other hand, conventionally proposed nylon fibers,
Bath towels made of synthetic fiber woven or knitted fabric such as polyester fiber and acrylic fiber have a high fiber modulus, so they excel in scraping off dirt and dirt. In addition, there is a problem that the skin is easily damaged and causes skin damage.
For the purpose of resolving these problems, bath towels using ultra-fine yarns of synthetic fibers have also been proposed, but there is a problem that the massage effect on the skin is too low and the feeling of use is not enough.

[0004]

SUMMARY OF THE INVENTION The present invention has been made on the background of the above-mentioned prior art, and has as its object a high retention of wet strength, a water absorption property, a dirt wiping property, a massage effect on the skin, It is still another object of the present invention to provide a bath towel which is excellent in properties such as foam elimination and the like, and has good usability and dirt removal properties.

[0005]

According to the study of the present inventors, the above object is to provide a bath towel made of a woven or knitted fabric containing paper yarn and hydrophobic fiber as constituent fibers, wherein the bath towel is made with respect to the weight of the woven or knitted fabric. The ratio of the paper yarn is 20 to 50% by weight, the ratio of the hydrophobic fiber is 50 to 80% by weight, and the hydrophobic fiber has a single fiber fineness of 1 to 25% by weight or more based on the weight of the woven or knitted fabric. It has been found that this can be achieved by a bath towel characterized by containing ultra-fine fibers of 0.1 dtex or less.

At this time, a water-resistant pulp tape obtained by spirally twisting a pulp tape having a water resistance of preferably 10 to 500 times / m is used as the paper thread, or a polyester fiber, a polyamide fiber, a polyurethane fiber as a hydrophobic fiber. The use of fibers, polypropylene fibers or acetate fibers has been found to be particularly good.

[0007]

Embodiments of the present invention will be described below in detail. The bath towel of the present invention is made of a woven or knitted material containing a paper thread and a hydrophobic fiber as constituent fibers, and the paper thread is formed, for example, by cutting pulp paper into a tape shape and twisting it. It is a string. As the raw material pulp, any pulp from a tree usually used for paper production can be used, but pulp obtained from conifers is particularly preferable since a fiber length is long and a high-strength paper thread can be obtained.

Since the strength of such paper made of pulp tends to decrease when water is absorbed, it is preferable to treat the paper with a water-resistant agent. The water-resistant agent is not particularly limited, but may be, for example, an epoxidized polyamide resin, an acrylate resin, a melamine resin, a urea resin, a wet paper strength enhancer such as polyethyleneimine, a polyacrylamide resin, polyvinyl alcohol, starch, carboxy. Dry paper strength enhancers such as methylcellulose can be mentioned, and in particular, the combined use of these wet paper strength enhancers and dry paper strength enhancers provides paper yarns that are excellent in water resistance and washing resistance and are less likely to fluff. It is preferred in that respect.

Any method of water-proofing the paper is optional. For example, a method of adding a predetermined amount of a water-resistant agent to a pulp dispersion liquid dispersed in water and then making the paper, or a method of adding a water-resistant agent to the paper obtained by making the pulp. A method of impregnating or applying a dissolved solution can be exemplified.

If the amount of the water-proofing agent is too small, the effect of improving the water resistance is small, while if it is too large, the paper becomes too hard and the feeling is reduced, so that 0.02 to 0.30 g per m ^{2 of} paper is used.
Is appropriate.

The basis weight of the paper is suitably in the range of 8 to 40 g / m ² in order to maintain the strength of the obtained paper yarn and facilitate the weaving operation. In addition, the width of the tape is the strength of the paper thread,
The range of 3 to 50 mm, particularly 3 to 15 mm, is suitable from the viewpoints of workability at the time of converting the tape into a paper thread, workability at the time of knitting and weaving, and the like. It is more preferable to reduce the thickness of the paper and increase the tape width, since the flexibility of the obtained paper yarn is improved and the paper yarn strength is also improved.

In order to make the tape-shaped paper into a cord-like shape, the tape-shaped paper may be twisted by a conventionally known method. In particular, spiral-twisting, that is, twisting into a form having a straw-shaped hollow inside. This is particularly preferable because the feel becomes good, and furthermore, moisture easily moves along the hollow portion, so that the water absorption / discharge property is improved and the stickiness is further improved. The number of spiral sweet twists is 1 from the viewpoint of hand and moisture transferability.
The range is preferably from 0 to 500 times / m, particularly preferably from 100 to 400 times / m.

As the other hydrophobic fiber constituting the woven or knitted fabric in the present invention, for example, a synthetic fiber or a semi-synthetic fiber made of polyamide, polyester, polyacrylonitrile, polyolefin, polyurethane, acetate or the like can be used. As the form of these fibers,
Any form such as a spun yarn, a filament yarn, and a processed yarn may be used, and the cross-sectional shape may be any of a round cross section, an irregular cross section, a cross section having a hollow portion, and the like. The hydrophobic fiber has a single fiber fineness of 1.1 dtex. It is necessary that the ratio of the following ultrafine fibers to the weight of the woven or knitted fabric is 25% by weight or more, and in particular, all of the hydrophobic fibers are ultrafine fibers having a single fiber fineness of 1.1 dtex, preferably 0.05 to 0.5 dtex. Desirably. If the content of the hydrophobic ultrafine fibers is less than 25% by weight, the performance of removing dirt becomes insufficient, and a good drying rate cannot be achieved while suppressing a decrease in strength at the time of wetting. . The cross-sectional shape of the ultrafine fiber is preferably a cross-sectional shape having an edge such as a triangular cross-section, because the dirt wiping property is further improved.

Next, the ratio of the paper yarn and the hydrophobic fiber in the woven or knitted fabric is 20 to 50% by weight, preferably 30 to 50% by weight, and the latter is 50 to 80% by weight.
Preferably, it must be in the range of 50 to 70% by weight.
When the proportion of the paper yarn exceeds 50% by weight, the strength decrease when wet becomes large and the drying speed becomes slow.
If the amount is less than 0% by weight, the massage effect on the skin is reduced. When the proportion of the hydrophobic fiber is less than 50% by weight, the strength at the time of wetting is greatly reduced and the dirt removal performance is reduced. On the other hand, when the proportion is more than 80% by weight, the proportion of the paper yarn is reduced. Since the content cannot be increased to 20% by weight or more, the massage effect on the skin is reduced.

In the present invention, as long as the above requirements are satisfied, the single fiber fineness of the hydrophobic fibers other than the ultrafine fibers having a single fiber of more than 1.1 dtex is not particularly limited. Those having a range of 1.5 to 5.5 dtex are used. In addition, hydrophilic fibers such as rayon fibers and hemp fibers other than paper yarns and hydrophobic fibers may be contained within a range not to impair the object of the present invention.

The woven or knitted fabric containing the above-described paper yarn and hydrophobic fiber as constituent fibers may be of any knitting and weaving method as long as the above requirements are satisfied. Yarns, hydrophobic fibers may be arranged in the other direction, or a cross-knitted fabric in which paper yarns and hydrophobic fibers alternately appear in each of the longitudinal and weft directions, or the paper yarn and the hydrophobic fibers may be arranged in a predetermined manner. The yarns may be drawn together at a ratio of 2 to form a twisted yarn if necessary, and then knitted and woven into a desired woven structure.

The density of the woven or knitted fabric is not particularly limited and can be appropriately set as required, but is suitably in the range of 150 to 300 g / m ² , and particularly preferably in the range of 200 to 250 g / m ² .
