Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wiping handkerchief composed of a single cloth obtained by arranging superfine multifilament yarns of synthetic fibers and hydrophilic fibers and woven or knitted.

[0002]

2. Description of the Related Art A large number of eyeglass wiping cloths and wiping cloths made of ultrafine fiber yarns of synthetic fibers such as polyester fibers and polyamide fibers have been proposed and put on the market. A large number of fabrics mainly made of hydrophilic fibers such as cotton and rayon are put on the market for the use of cloths and handkerchiefs. However, both of them have conventionally been used for different purposes, and few of them are made of the same cloth and have both water absorption performance and wiping performance such as sebum stain mainly composed of lipophilic component.

The water absorption performance can be improved by using a fabric made of hydrophilic fibers or by introducing hydrophilic groups on the surface of the hydrophobic fibers. Hydrophilic fibers such as cotton, rayon and acetate have high strength. Since it is weak and breaks after repeated use, it self-dusts and cannot be used favorably for wiping applications. Also, the latter has less problems of self-dusting because it is obtained by hydrophilizing the surface of hydrophobic fiber with excellent mechanical strength, but it has poor water absorption performance compared to hydrophilic fiber, and even if it diffuses water due to capillary phenomenon. Even if it does, it is not possible to expect a dramatic increase in absolute water absorption.

Further, in order to improve the wiping performance for use as a wiper, especially for the lipophilic stains mainly composed of sebum such as wiping glasses, there is no problem of self-dusting and the contact area with the wiping surface becomes larger. Such ultrafine fibers, more preferably a modified cross-section yarn or false twisted yarn of ultrafine fibers having a sharp edge in a single yarn cross section is preferably used. However, since the fiber is a hydrophobic fiber, it has extremely poor water absorbency and water retention, which causes a sticky feeling and backflow of water, which is not preferable for applications such as a handkerchief.

[0005]

DISCLOSURE OF THE INVENTION The object of the present invention is to achieve both water absorbency, water removability, and wiping property of lipophilic stains such as sebum, and the same problem as before with no problem of self-dusting at the time of wiping. It is an object of the present invention to provide a wiping handkerchief that can satisfy both properties that could not be achieved with the cloth.

A method for manufacturing the described wiping handkerchief.

In the present invention, the hydrophilic portion is composed mainly of hydrophilic fibers such as cotton and rayon, and the fabric is designed so that the hydrophobic portion composed mainly of polyester ultrafine fibers is divided. As a result, the former has a property of removing hydrophilic stains and water, and the latter has a property of wiping off hydrophobic stains containing oil and the like, and succeeded in achieving two different performances with the same fabric.

Further, conventional ultrafine multifilament yarns of hydrophobic synthetic fibers are mainly fibers obtained by a composite spinning method, but for ultrafineness, it is necessary to treat them with a solvent such as benzyl alcohol or formic acid. The environmental load is large in the process. Furthermore, it was undeniable that harmful solvent components could remain in the product, but by using ultrafine fibers obtained by direct melt spinning, there is no possibility of solvent remaining that would adversely affect the human body. It is possible to eliminate the problem of processing waste liquid required.

The present invention will be described in detail below.

The hydrophilic fibers used in the wiping handkerchief of the present invention are preferably composed mainly of cellulosic fibers, such as cotton, rayon, polynosic, cellulose triacetate,
Cellulose diacetate and the like can be exemplified, and in particular, the use of a composite spun yarn such as a cotton spun yarn or a finely spun twisted yarn mainly composed of cotton is effective from the viewpoint of slipping and slipping-off resistance of a fabric structure. As the hydrophilic fiber, it is of course possible to use a multifilament yarn other than the spun yarn. When spun yarn or composite spun yarn is used, it is more effective to use twined yarns or triple twists than to use spun yarns from the viewpoint of appearance quality as a wiping handkerchief, cloth strength and self-dust suppression. . Depending on the product, caustic soda such as mercerized cotton or mercerized cotton or cotton spun yarn treated with liquid ammonia may be used.

Further, when spun yarn is used, the fluff may be exposed on the surface and impair the surface appearance quality. Therefore, the surface fluff can be removed by an enzymatic treatment such as roasted fluff or cellulase in the finishing and rearranging steps. desirable. If necessary, various finishing processes and finishing resin processes may be applied. After the fabric structure is treated with caustic soda and liquid ammonia, the cotton side is mercerized to obtain the strength, quality, dyeability, etc. of the cotton fiber. May be improved.

Examples of synthetic fiber raw materials used as synthetic fiber multifilament yarns and synthetic fiber multifilament false twisted yarns include general-purpose polymers such as polyester, polyamide and polyolefin. Polyester is most preferred, and it is preferably used in view of handleability, mechanical performance, dyeability, and price. Particularly, polyethylene terephthalate fiber having ethylene terephthalate as a main repeating unit is preferable. Matting agent,
A third component such as a pigment may be added, or in order to prevent deterioration of dyeing fastness with a disperse dye, a copolymer obtained by copolymerizing 5-sodiumsulfoisophthalic acid in an amount of 5 to 15 mol% is used. It is also possible to adopt a dyeing recipe.

In order to expose a large amount of synthetic fiber multifilament yarn and synthetic fiber multifilament false twisted yarn on the surface of the fabric, a satin weave structure is preferably used, and the portion where the fibers are interwoven with the warp yarn is a warp satin design, It is desirable that the portion where the fibers are interwoven with the weft is woven as a weft satin design. As for the floating number ratio of synthetic fibers / hydrophilic fibers in the satin weave 1 complete structure, 3/2 to 7/1 is effective in terms of wiping performance and consumption performance. When the floating number is less than 3/2, the hydrophilic fibers are exposed to a large extent, and the ability to wipe lipophilic stains such as sebum is deteriorated. If the number of floats exceeds 7/1, the degree of surface exposure on the synthetic fiber side is large and the ability to wipe off lipophilic stains is improved. The appearance quality may be significantly impaired depending on the number of times of use, which is not preferable. A more preferable float number ratio is in the range of 3/2 to 4/1.

The cross-sectional shape of the single yarn of the synthetic fiber multifilament is not particularly limited, and a circular cross section, a triangular cross section,
It may be a flat cross section, a multilobe cross section, or any other irregular cross section. A cross section with sharp edges is more effective in consideration of the ability to wipe off lipophilic stains, and it is more effective, and false twisting is performed to distort the single yarn cross section, giving sharp edges and fine solid stains due to crimping. It is also preferably adopted to improve the capturing ability of Considering the removability of dirt, it is effective to increase the contact area with respect to the wiping surface.
It is preferable to increase the number of constituent single yarns and to further increase the contact area between the single yarns and the wiping surface by adopting an irregular cross section.

It is desirable to use a texture selected from plain weave, stone weave, twill weave, and twill weave for the portion where a large amount of hydrophilic fibers are exposed on the surface of the fabric. Since the satin weave structure is used in the part where the synthetic fibers are exposed on the surface of the fabric, it is desirable for the weaving operability that the part that is mainly woven by the hydrophilic fibers also has a structure close to the satin weave structure. However, the fabric itself becomes heavy, and as a result of hydrophilic fibers that have high water absorption performance covering the surface layer, moisture is mainly diffused on the surface of the fabric, and the back surface is dry but the surface feels sticky. It is not preferable as a feeling of use of the handkerchief.

It is desirable that the portion mainly composed of the hydrophilic fiber has a structure in which the warp and the weft are exposed to the surface at substantially the same ratio, such as a plain weave, a stone weave, and a weave. 3/2 twill or the like is suitable. Further, it is desirable to adopt the above-mentioned woven structure also from the viewpoint of fabric strength and dimensional stability.

A rapier room, an air jet room, and a projectile room are suitable as the loom used for manufacturing the wiping handkerchief of the present invention, and it is desirable that the loom can simultaneously set two weaver beams. Both of the weavers beams are more preferably equipped with a positive feeding mechanism, and as the opening device, either a dobby opening or a jacquard opening can be used, but the latter is preferable from the viewpoint of weaving and design. Is preferred.

Further, it is more preferable that the loom is equipped with a winding stop device so that the weft input amount can be changed appropriately, and it is possible to easily weave check patterns and border patterns by changing the yarns. Possible and preferred. In particular, when inserting synthetic fiber multifilament yarn and / or synthetic fiber multifilament false twisted yarn into weft as weft satin structure, it is necessary to increase the number of weft insertions from the number of hydrophilic fiber weft insertions so that slip or seam slippage may occur. From the perspective of.

The single yarn fineness of the synthetic fiber multifilament yarn and / or the synthetic fiber multifilament false twisted yarn is 0.4 dtex / fil. Or less, more preferably 0.3 dtex / f
il. Or less, more preferably 0.25 dtex / fil. It is the following. The single yarn fineness is 0.4 dtex / fil. If it exceeds, the contact area per total fineness to the wiping surface becomes small, and good removability by wiping cannot be obtained. The lower limit value of the single yarn fineness is not particularly specified, but it is 0.1 dtex / fil. The above is preferable. At present, single yarn fineness less than this can be obtained only by complex melt spinning and elution splitting with an organic solvent or swelling / peeling splitting to make it extremely fine, and there is a problem of waste liquid treatment and skin damage due to solvent remaining in the fabric structure. Such problems are expected. In addition, the strength per single fiber is reduced due to the effect of reducing the cross-sectional area, and cutting fluff due to pressing and rubbing at the time of wiping is caused to deteriorate the wiping performance, which is not preferable.

The number of single filaments of the synthetic fiber is 100 / yarn or more, more preferably 150 / yarn or more,
It is more preferable that the number of yarns per yarn is 180 or more because the wiping performance can be improved. When the number of constituent single yarns is less than 100 yarns / yarn, the number of single yarns in contact with the wiping surface becomes too small, so that good wiping performance cannot be obtained. The upper limit of the number of constituent single yarns of the synthetic fiber is not particularly limited, but in consideration of the single yarn fineness and the material thickness as a handkerchief, up to about 1000 yarns / yarn is a preferable range.

When weaving the wiping handkerchief of the present invention, it is effective to add a sizing agent to the synthetic fiber side and the hydrophilic fiber side in order to improve the weaving operability. On the synthetic fiber side, in addition to PVA and acrylic glue, melting point 40-50 ° C
Paraffin wax of about a certain degree is preferably used, and starch paste such as corn starch and PVA are preferably used on the hydrophilic fiber side. Of course, a plurality of sizing agent components may be blended and formulated. In particular, when the hydrophilic fiber is a short fiber spun yarn such as cotton, it is important to sufficiently maintain the strength and elongation in weaving while considering the conjugation property from the viewpoint of fluff binding and the like.

In the wiping handkerchief of the present invention, the synthetic fiber multifilament yarn and / or the synthetic fiber multifilament false twisted yarn is inserted with the actual twist in the following range. (Equation 3) 700 / √ (D × 0.90) ≦ Tw ≦ 6200 / √ (D × 0.90) where Tw is the number of actual twists per 1 m of yarn (turns / m), and D is a multifilament yarn. Shows the total fineness (dtex) of. The number of real twist insertion is 70
If it is a very sweet twist of less than 0 / √ (D × 0.90) times / m,
Poor shedding during weaving is likely to occur, leading to weaving defects. Further, in the range exceeding 6200 / √ (D × 0.90) times / m, it is necessary to carry out the twisted yarn set by steam using a rideon box or a kettle in order to suppress the twisted torque after twisting. Twisting torque is developed by rubbing and tensioning during weaving, and problems such as warp, snare, and twist are likely to occur on the loom. Further, since the single yarn constituting the multifilament yarn is packed more finely due to the migration effect of the yarn, the removability of fine solid particles by wiping is deteriorated, which is not preferable.

The wiping handkerchief of the present invention is composed of a synthetic fiber multifilament yarn, and / or a fabric structure made of synthetic fiber multifilament false twisted yarn and hydrophilic fiber, and a fabric for dyeing both of them. The structure may be a dip dyeing two-bath dyeing method, a method in which yarns are dyed with each other and then woven, a method in which one is dyed with a yarn and then the other is dyed by dip dyeing, and the like. Of course, not only dip dyeing, but also inkjet, flat screen,
It may be used together with printing such as a rotary screen. If necessary, various resin processing, shrink-proofing processing, water absorption processing, antibacterial and deodorizing processing, deodorizing processing, UV cutting processing and the like can be used in combination. For items such as handkerchiefs that emphasize design, by dyeing them together and weaving them, it is possible to prevent contamination of each other and express a beautiful chambray effect and contrasting color effect. This is preferable because it can be easily found during weaving.
