Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a fabric having a special structure. More specifically, the present invention relates to a method for producing a fabric having a special structure that can prevent rain from penetrating into clothes when used as clothes and can form clothes having good ventilation performance.

[0002]

2. Description of the Related Art The summer in Japan is extremely hot and humid. In recent years, people have come to demand greater comfort. Temperature control such as coolers is becoming more and more common in buildings, but if you go outside for a while, you will be forced to put yourself in the extreme heat and sultry environment of nature. In order to avoid the sun in the summer, even if you wear clothes made of hemp, which is currently considered the best summer clothing, if it has long sleeves, it will be hot and humid, and if it has short sleeves, it will get sunburned. . In this regard, it is often the case that the functional properties of the fiber material itself are not sufficient at the time of strong direct sunlight, hot weather, and excessive sweating.

On the other hand, when playing sports on a rainy summer day, if you wear waterproof clothing to prevent getting wet, even if it is moisture-permeable waterproof clothing, it will not only be hot and humid, but also your body. There is a problem that the sweat from the inside gets wet inside from the inside rather than getting wet from outside. Even a high-density woven or knit fabric that has been developed in recent years and has both water repellency and waterproofness and high moisture permeability is sufficient.

Although many clothing materials for warming winter have been developed at present, there is no clothing that can be worn cool in the summer. To solve this problem, we have created a fabric that has both high air permeability and light-shielding and water-proof properties, and is rich in fashionability. A special fabric and a method for producing the same have been proposed, which form a superposed structure that allows the fabric to be breathable.

As a manufacturing method for forming such a ventilation structure, a temporary fixing agent is used to temporarily fix the narrow sheet-like material while forming the overlapping structure, or after the overlapping structure is formed, temporary fixing is performed. Then, there is a method in which the temporary fixing agent is removed after the connection treatment. However, in a method of temporarily fixing such a narrow sheet material using a temporary fixing agent, if a narrow sheet material having water repellency is used in advance for production in order to have water repellency, The immobilizing agent is difficult to deposit, is difficult to temporarily fix, and is difficult to process.

[0006]

In view of the above-mentioned problems, the present invention can easily form a superposed structure even if a narrow sheet material having water repellency is used in advance, and is waterproof and water repellent. While having performance, it has a ventilation structure, and it does not get stuffy from the inside even on rainy days, especially in summer, it can be worn as a cooler and more comfortable clothing, and as a novel fashionable clothing. It is an object of the present invention to provide a method for producing a special cloth.

[0007]

In order to achieve the above-mentioned object, the present invention has the following constitution.

That is, the method for producing a fabric having a special structure according to the present invention is such that a continuous narrow sheet material having water repellency and / or a large number of narrow sheet materials having a certain length are sequentially stacked while shifting their positions. When forming a superposed structure composed of narrow sheet-like materials, a special feature is characterized in that the narrow sheet-like material is temporarily fixed using a sizing agent to which a surfactant is added to form the superposed structure. It is a method of manufacturing a fabric having a structure.

Alternatively, in the method for producing a fabric having a special structure of the present invention, a continuous narrow sheet material having water repellency and / or a large number of narrow sheet materials having a certain length are sequentially displaced. When overlapping and forming a superposed structure composed of narrow sheet-like materials, the narrow sheet-like materials are temporarily fixed by using a sizing agent to which a surfactant is added to form a superposed structure, and the superposed structure state is formed. A method for producing a fabric having a special structure, characterized in that adjacent narrow sheet-like materials are connected while being maintained, and then the sizing agent is removed.

[0010]

In the special cloth obtained by the method of the present invention, a large number of narrow sheet-like products are used, and a large number of these narrow sheet-like products are stacked in multiple stages while shifting their positions. When temporarily fixing with a fixing agent, the basic constitutional requirement is that the narrow fixing sheet having water repellency contains a surfactant in the temporary fixing agent. In the present invention, the narrow sheet-like article may be any sheet-like article having a width narrower than its length, and its width is not particularly limited. Preferably 1 to 200 m
Examples include sheet materials such as woven fabrics, knitted fabrics, non-woven fabrics and films having a width of m. Especially as a clothing material,
Alternatively, for applications such as bedding including curtains, it is preferable to use a narrow sheet-like material made of a woven or knitted material in order to make the effects of the present invention more effective and also in workability in manufacturing. . For example, when used as a clothing material, from the viewpoint of the feel of clothes, the narrow sheet material base material may be polyester fiber, polyamide fiber typified by nylon, synthetic fibers such as acrylic fiber, rayon, cupra and the like. Cellulose regenerated fibers, semi-synthetic fibers such as acetate and triacetate, cotton,
Natural fibers such as hemp, silk, and wool are preferable, and these fibers may be used alone or in combination, mixed fiber, mixed fiber, mixed twist,
It is used in combination depending on the purpose, such as mixed weaving. It is also preferable to use various textured yarns such as bulky textured yarn to achieve bulky up and a sharp feel.

Such a thin sheet material can be woven by a ribbon loom or a sheet material loom at a desired weaving width, by a wide width weaving machine, or by a fusing cutter on the machine or after the weaving is completed. There is a method of melt-cutting to a width, and a method of interweaving the easily-dissolvable fibers in the boundary portion to be slit and then dissolving the easily-dissolvable fibers after weaving to obtain a desired narrow width woven fabric. A specific method may be appropriately selected in consideration of workability, specifications of a desired narrow sheet-like material, and the like.

The narrow sheet material having water repellency as used in the present invention means the above-mentioned narrow sheet material which has been previously subjected to water repellent treatment. The water repellent used for such treatment is
Paraffin, fatty acid amide, alkyl ethylene urea,
Conventionally known or well known materials such as silicone type and fluorine type can be widely applied. Among these, silicone-based and fluorine-based ones are preferable from the viewpoint of water repellency, and further fluorine-based ones are particularly preferably applied because they have extremely high water repellency and have good oil repellency. .
The fluorine-based water repellent referred to in the present invention is a fluorine-containing polymer having a perfluoroalkyl group in its side chain, which is publicly known or well known in the art. For example, polymers and copolymers of the following monomers are common.

[0013]

[Chemical 1]

Here, R ₁ is hydrogen or a methyl group, and R ₁ is
₂ represents a methyl group or an ethyl group. n is an integer of 3 to 21.

The sizing agent used as the temporary fixing agent is
Polyvinyl alcohol, starch, carboxymethyl cellulose, methyl cellulose, hydroxymethyl cellulose, polyacrylic acid salts and the like which have been publicly known or well known can be used and are not particularly limited.

However, as a matter of course, the excellent water-repellent performance of the sheet means that the cloth which is provided with the water-repellent agent is difficult to be pasted with the glue which is the temporary fixing agent, and is difficult to temporarily fix, and the narrow sheet The material is likely to come off, which makes subsequent processing difficult. In particular, this problem becomes remarkable with a fluorine-based water repellent having excellent water repellent performance, and it has been virtually impossible to perform temporary fixing with a sizing agent.

Therefore, the inventors of the present invention boldly challenged the problem of providing a temporary fixing agent to the water-repellent agent-provided fabric to enable superposition processing, and as a result, added a surfactant to the temporary fixing agent. By doing so, the inventors have found a method in which the temporary fixing agent is well adapted to the water-repellent agent-applied cloth, and it is possible to superimpose a narrow sheet-like material.

Such a surfactant is appropriately used depending on the material of the cloth, the kind of the water repellent, the purpose of use of the special cloth, and the like. However, in order to make its effect preferable, it is preferable to use the surfactant in combination with the water repellent agent applied to the cloth. That is, for example, it is preferable to apply the fluorine-based surfactant to the cloth to which the fluorine-based water repellent is applied, in particular.

Such a fluorine-containing surfactant is a perfluoroalkyl group obtained by replacing a hydrogen atom in a hydrophobic long-chain alkyl group of a general hydrocarbon-based surfactant with a fluorine atom and various soluble atomic groups. Being represented.
For example, perfluoroalkyl sulfonate, perfluoroalkyl carboxylic acid, perfluoroalkyl ethylene oxide adduct, perfluoroalkyl trimethyl ammonium salt, perfluoroalkyl phosphate ester,
In addition, a perfluoroalkyl group and various hydrophilic groups are linked. These are used as aqueous solutions, emulsions, suspensions, dispersions and the like. Further, it can be used not only as an aqueous system but also as a system in which various solvents such as alcohols, ketones and aldehydes are used in combination.

The water-repellent treatment may be carried out on a wide sheet and then formed into a narrow sheet, or may be formed into a narrow sheet first and then subjected to a water-repellent treatment. Good. Of course, the resin may be coated not only for water repellency but also for waterproofing.

In the special cloth of the present invention,
The overlapping degree of each of the narrow width sheet-like materials may be such that they overlap regularly in the same width, or may overlap in a random width. Further, not only the narrow sheet of the same material is used, but also narrow sheets of two or more different materials or different colors and patterns are alternately or with a certain pattern, for example, a white narrow sheet material and a red sheet. Alternately, such as using the narrow sheet material of No. 3, repeating each of the white, red, and yellow narrow sheet materials in this order, or repeating as white-red-white-yellow-white-red ... It is also preferable to form a superposed structure with an arrangement of your choice, since not only the design but also the one with a very high sensitivity can be obtained.

As a method of connecting and fixing such a large number of narrow sheet-like materials in a state of being stacked in multiple stages, for example, a method of connecting using a quilting sewing machine can be used. At this time, the connection is not limited to the straight stitch, and may be sewn with a sewing machine so that a zigzag pattern or various geometric patterns can be obtained, or by using a double needle to connect like a double stitch. Good.

The method for forming a laminated structure fabric using a large number of narrow sheet materials can be manufactured by various specific methods, and is not necessarily limited, but for example, A narrow-width sheet-like material impregnated with the above-mentioned sizing agent containing a surfactant is wound around a rotating drum of appropriate size while shifting the position sequentially to the desired stacking width, and dried to form an adjacent narrow-width sheet-like shape. After temporarily adhering the objects to each other, they are removed from the drum to obtain a temporary adhering sheet in which narrow sheet-like objects have a superposed structure and are fixed with glue. Thereafter, the temporary adhesive sheet is hung on the sewing machine at an appropriate interval, and a large number of narrow sheet-like objects having a superposition structure are provided at regular intervals,
Alternatively, they are sewn together at random intervals, and then
The superposed structure fabric can be obtained by dissolving and removing the sizing agent used for temporary adhesion, although it may be after the sewing treatment or before the sewing.

The special cloth of the present invention can be sewn on sportswear such as golf wear and tennis wear, and a raincoat by using the superposed structure cloth.

It can also be obtained by removing the sizing agent before sewing, cutting in a superposed structure fabric state, and sewing.

When sewing, the special fabric of the present invention may be used by 100%, or may be used by being partially used in combination with other fabric materials.

As described above, the method for producing a fabric having a special structure of the present invention uses a temporary fixing agent containing a surfactant when forming a narrow sheet-like material having water repellency into a superposed structure. There is a feature in the method of fixing, and by using such a method, it is possible to form a superposed structure neatly even with a narrow sheet having water repellency, and it is possible to perform water repellent treatment after sewing. In this case, it is possible to perform a water repellent treatment in the form of a piece of cloth in advance.

By such a method, it is possible to prevent rain from entering, to make comfortable waterproof clothing that does not get damp, and to prevent sunburn due to strong sunlight especially in summer, and to make it breathable. It is suitable for rich and cool clothes.

Since it has many features such as sharpness, three-dimensionality, and unique appearance and high fashionability, it is completely new to sportswear such as golf wear and tennis wear, and rain gear such as raincoats. In addition, it can be widely used for various kinds of casual clothes, bedding such as curtains and stands, hats, shoes, tents, and packing cases for fresh food.

EXAMPLES In the examples, all "percentages" are by weight.

Example 1 Nylon flat yarn was used as the warp, and a wide taffeta fabric made of nylon normal yarn was used as the weft, and after wrinkling, it was colored blue. Then, a fluorine-based water repellent was impregnated and applied, and one surface of the taffeta was further coated with the fluorine-based water repellent.

Thereafter, the cloth was cut into a width of 36 mm using a fusing cutter to obtain a large number of narrow sheet-like products.
Then, a large number of narrow sheet-like materials were connected to form one long sheet-like material.

This narrow sheet-like material is dipped in a water-soluble polyvinyl alcohol paste containing 1% by weight of a fluorosurfactant, and the overlapping width is the width of the sheet-like material on a rotating cylindrical drum. The sheet-like material was wound while being moved so as to be 1/3 of 12 mm. The sheet-like material thus obtained by winding the sheet-like material around the superposed structure was dried and then cut in the axial direction of the drum to obtain a sheet. This sheet was obtained by tightly superposing a narrow sheet-like material with a polyvinyl alcohol sizing agent.

Next, the sheets were hung by a quilting sewing machine at equal intervals of 2 inches so that the narrow sheet-like materials were sewn by a sewing machine and connected to each other.

Then, golf wear was sewn using the continuous cloth. After sewing, the sizing agent was dissolved and removed in water at 50 ° C. and dried.

Thus, the width is 36 mm, the overlapping width is 12 mm,
A three-dimensional golf wear having a superposed structure having a continuous width of 50 mm and having a narrow sheet-like material having good water repellency as well as water repellency was obtained.

Wearing such clothes, the player actually went out to the golf course and played. On the day of the event, it rained lightly, but it did not get wet with rain, it had excellent breathability, it had a crisp texture, and it was extremely comfortable to wear.

Comparative Example 1 An attempt was made to form a superposed structure in the same manner as in Example 1 except that the same narrow sheet material as that obtained in Example 1 was added with a surfactant. Since the cloth was repelled by the polyvinyl alcohol water-soluble sizing agent and completely unfamiliar, it could not be temporarily fixed and a cloth having a superposed structure could not be prepared.

[0039]

Industrial Applicability According to the present invention, a continuous narrow sheet material having water repellency and / or a large number of narrow sheet materials having a certain length are sequentially superposed while shifting their positions, and the superposed narrow sheet materials are superposed. When a structure is formed, by adding a sizing agent to which a surfactant is added, the penetrability and adhesiveness of the sizing agent to the sheet-like material are improved, and a preferable superposed structure can be formed.

Due to such an effect, adjacent narrow sheet-like materials can be connected to each other while maintaining a strong superposed structure state, and then the sizing agent is removed to form a ventilation structure composed of the narrow sheet-like materials. It is possible to form the preferable superposed fabric having the above-mentioned processability and handleability.
