Description

  The present invention relates to a fabric excellent in suction dehydration and drainage and a suction dehydration method for products capable of spreading and sucking dehydration and draining without causing wrinkles on the surface of the fabric.

  As a method for removing moisture from fabrics and textiles containing moisture and from fabrics and textiles to which moisture has adhered, a method of removing moisture by drying with wind or heat after removing moisture in general is generally used. It is. Specific methods for removing moisture include a method in which the product is left in a suspended state and dehydrated by natural fall, a forced force, for example, a centrifugal dehydration method in which water is shaken off using a centrifugal force after washing, a rubber roll, etc. There is a method in which a cloth is passed through, and water droplets adhering to the surface of the cloth or product, water that has permeated into the inside, and the like are squeezed and dehydrated. Thereafter, it is common to use air-drying removal or dry-drying using a drum dryer or the like that uses heat for quick removal.

The centrifugal dehydration method that physically removes water with a forced force is a method in which a cloth or textile product wetted in a rotating drum or wet with water drops after washing is centrifuged in a drum. Centrifugal dehydration is a common dehydration method that uses force to remove moisture.
Old washing machines have two rubber rolls, and the rubber rolls come with a handle to rotate. After washing, adjust the gap between the rubber rolls after washing, and put the rubber gap between these rubber rolls by operating the handle. The method of squeezing and removing by passing and forcibly removing moisture and water droplets was the squeeze dehydration method in familiar cases.

In the centrifugal dehydration method, the fabric and clothing are put in a folded state. As a result, dewatered and squeezed wrinkles are newly generated in the dehydrated fabric and products together with the wrinkles during washing, and these remain after drying. Basically ironing etc. was necessary to remove the wrinkles.
In recent washing machines, a drum drying method in which moisture is dried and removed using hot air after washing and dehydration is common. In this case, heat drying is performed in a folded state, so that fixing of the bag occurs. It is difficult to remove and strong heels are fixed on the fabric. In particular, in the case of thermoplastic fibers, the fixing is strongly performed.
Furthermore, as a result of being dehydrated in a folded state, dehydration is poor at the overlapping portions of the fabric and product, and it is not uniform, and dewatering spots occur at many places. This tendency is more likely when the amount of laundry put into the centrifugal dewatering tank increases. In addition, fabrics and clothes having poor air permeability tend to occur more easily.
The dewatering method of the squeezing and removing method is also the same as or more than the centrifugal dewatering method if the cloth and product after washing are rope-like or entangled, and the water is squeezed and removed as it is. In addition, wrinkles and dehydration occur.
Furthermore, when performing manually, the water | moisture-content removal efficiency of a roll pressing system tends to be bad.

These dewatering methods not only have no function of correcting wrinkles generated during washing, but also generate new strong wrinkles during dehydration.
The work that the dehydration method that does not generate new wrinkles in the cloth and textiles at the time of dehydration, the method of removing water droplets, the dehydration method that does not generate dehydration spots, and the dehydration droplet method, which are the disadvantages of these dehydration methods, perform the above operations There has been a strong demand in the field and in the field where fabrics and textile products are handled. Furthermore, since the folds are folded using hot air and dried in a state with wrinkles, the wrinkles are fixed more strongly, so improvement in this respect has also been demanded.
There has also been a demand for fabrics and textiles that can remove moisture and water droplets more effectively and more easily than conventional fabrics and products, and fabrics and textiles that have a low moisture content.
The invention of the present application is a spreading type moisture removal that efficiently removes water droplets and moisture from fabrics and textile products without causing the above-mentioned dewatering soot and dewatering spots (removal of moisture and water droplets while the fabric is spread). And the provision of fabrics and textiles suitable for the removal method.
TECHNICAL FIELD The present invention relates to a cloth-type moisture, a water droplet removal method and a water-drop, fabric that can be easily removed by removing moisture in a spread state, and a textile product. Has an invention relating to a dehydration method having a feature that does not cause dehydration. In the present invention, the dehydration and dehydration method is hereinafter referred to as the spread suction dehydration and the spread suction dehydration method.
Furthermore, when the present invention is applied to the field of hospitals or nursing care, in addition to water and water droplets, spilled urine, body fluids, and fluid vomit are also targeted.
In this way, there is a similar need in the market for a removal method that can easily remove urine, body fluids and fluid vomit in addition to moisture and water droplets from fabrics and textile products, and fabrics and textile products that can be removed easily. Therefore, the present invention relating to moisture can be applied to hospitals and nursing care fields as they are.
In the following expression of the present invention, the expression of moisture and water droplets includes liquid substances such as urine, body fluid, fluid vomit, and filth.
Furthermore, the expression of water, liquid, water droplets and droplets is expressed as moisture or water droplets unless otherwise required. Furthermore, the expression of water or water droplets is expressed as moisture unless otherwise required.
As described above, contents of drainage, drainage, liquid removal, and liquid removal properties are included unless the expression of dehydration and dehydration requires special distinction.
A product capable of spreading and sucking and dehydrating without causing dehydration on the surface of the fabric refers to a textile product such as clothing, clothing, sheets, and carver that can be dehydrated in the above-described expanded state.
The expression “spreading and sucking dewatering” means sucking and dehydrating in the spread state and sucking and dehydrating in the product state. The “spreading and sucking dewatering device” can perform sucking and dewatering in the spread state and in the product state. Means a device.

Japanese Patent Application No. 2002-16622 (Reference Document 1) The patent document of Reference 1 is a patent relating to a fiber structure. [0001] of Reference Document 1 states that “the present invention relates to a fiber structure excellent in water repellency, and more particularly to a fiber structure excellent in low water wettability even when used under conditions where water exposure is remarkable, such as in water. More specifically, this reference document relates to a knitted fabric with low water wettability, as described in `` it relates to a fiber structure excellent in low water wettability suitable for swimsuits, etc. '' The present invention relates to an invention having a feature of low water wettability. The present invention relates to a fabric and a textile product that can easily remove moisture by the spread-sucking dehydration method, and relates to a dehydration method that does not generate dewatering soot, and has low water retention after dehydration. In other words, although the water retention value is the same, the low wettability evaluation of this reference is evaluated by the ratio of the amount of water that is sucked into the water (water content). Is evaluated by the retention rate of water after suction dehydration (suction dehydration water retention rate), and the content of water retention is different. Further, this reference document also suggests the description of the moisture removal method by the fabric suction and dehydration method of the configuration of the present invention and the description of the fabric configuration and fabric processing means for obtaining a fabric having good suction and dewaterability. There is no description. With respect to processing, only a description relating to normal water-repellent processing is described.

Japanese Patent Application No. 2010-250908 (Reference Document 2) The patent of Reference Document 2 is a school uniform, student pants, and work clothes using a quick-drying fabric characterized in that the dehydration rate of washing and dehydration is 50% or less. And any textile product selected from the group consisting of uniforms. The description related to the washing and dehydration water retention rate in claim 2 of Reference 2 is a description related to moisture retention similar to the suction dehydration retention rate and the suction dehydration retention rate in the water retention evaluation of the present invention. The water retention rate is the water retention rate after washing and dehydration. That is, it is dehydrated by a dehydration method using centrifugal force, and evaluated by a measured value of the ratio of the retained water amount after dehydration (the retained water amount by the centrifugal dehydration method). On the other hand, the evaluation method is different from the suction dehydration water retention rate and the suction dehydration water retention rate in the suction dehydration water method and the suction dehydration method of the present invention. Reference literature is a centrifugal dehydration method, and the present invention is a suction dehydration method and a suction dehydration method, and the dehydration mechanism is different. This reference document is an evaluation method in which the evaluation conditions are slightly different from the water retention rate used for the evaluation of the present invention of the combination of the fabric and the specific woven fabric of the present invention of claim 12 and the multistage hydrophobization treatment. It is almost the same itself. This reference document is also an invention that devise the yarn and woven structure to reduce the limited water dehydration rate of washing, and only describes a normal water-repellent process for processing. On the other hand, the invention of the present application is also an invention relating to an effect obtained by combining a specially constructed yarn, a specially constructed fabric and a multi-stage hydrophobizing process. In this reference document, there is no description or suggestion regarding multi-stage processing. The configuration requirements are also partially different. Furthermore, for the purpose of quick drying, the water dehydration rate for washing is 50% or less, more preferably 20% or less, and particularly preferably 5 to 20%, but this preferable water retention range is achieved. There is no description about the special water repellent finish. The invention of the present application is different in both the achievement target and the achievement numerical value itself, which are “a water-repellent fabric having a water retention rate of 5% or less and a feeling of contact wettability”. In this reference document, there is no description about the means for making the water retention of 5% or less of the present invention. Furthermore, the present invention relates to a fabric and a textile product that can be easily removed with a spread-sucking dehydration method, and a dehydration method that does not generate dewatering soot, and has low water retention after dehydration. That is, it is common in the point that water retention capacity is small (point to make it small), but this reference document also includes a description of a method for removing moisture without generating wrinkles by the spread suction dehydration method of the configuration of the present invention. There is no special description regarding the fabric configuration or fabric processing means for obtaining a fabric with good properties, nor any description suggesting this. Regarding the processing, as described above, the description is only related to the normal water-repellent processing common to the present invention except that there is a description related to a preferable prescription. In the present invention, in addition to the usual water-repellent processing common to the reference literature, repeated dipping and drawing are performed so as to exert an effect on a fabric using a dense fabric, a yarn having a dense yarn structure (for example, a strongly twisted yarn). The continuous water-repellent treatment (multi-stage treatment) and batch-type water-repellent treatment with repeated nip and impregnation are also invented, but there is no description about this. This Reference Document 2 is a product-related patent and is partially common in this respect. However, as explained in [Background Art] of the specification of the present invention, when the product is washed and dehydrated as in Reference 2, not only the occurrence of dehydration spots is unavoidable, but also the wrinkles at the time of washing In addition, generation of soot during dehydration is inevitable. This is also completely different from the present invention product of the present invention of the present invention of the spread suction dehydration method that does not generate wrinkles. Furthermore, in this Reference Document 2, neither a description relating to the configuration of the present invention nor a description suggesting this is found. This Reference Document 2 is an invention relating to a specific fabric obtained by applying a specific twisted yarn to a specific yarn, and a low water-holding fabric after centrifugal dehydration used for a specific application. The product of the present invention is an invention as described above. The structure and purpose are completely different.

The problem to be solved by the present invention is that water or liquid adhering to the surface of the fabric, water or liquid that has penetrated into the inside of the fiber, or fiber product is not newly dewatered on the surface of the fabric or fiber product at the time of dehydration. Further, the present invention relates to a dehydration / liquid removal method for removing water droplets, liquid droplets, moisture and liquid uniformly.
Centrifugal dehydration attached to the washing machine or combined with the washing machine and mangle squeeze type dehydration, fabrics and textiles may generate additional dewatering squeezed and squeezed slag that occurs during washing, and dewatering spots will occur. Preventing the occurrence of this is one of the issues.
Furthermore, it is another subject to provide a fabric and a textile product that can easily carry out this spreading water removal method. Fabrics and textile products that are the subject of the present invention are made from fabrics of relatively light weight (500 g / m2 or less) such as general clothing and sheets, clothes such as carver, and nursing clothing such as sheets and carver. Conventionally, personal items that have been washed mainly in home washing machines are the target.

The present invention allows a fabric or textile product containing moisture, a suction dewatering device capable of scanning the surface of a fabric or textile product to which moisture has adhered to the fabric in an expanded state to scan the fabric and penetrate water droplets or fabric attached to the surface. This is a method for removing the moisture by sucking out the moisture.
Furthermore, we developed a fabric with excellent spreading and sucking and dewatering properties that is easy to remove moisture by spreading and sucking and dewatering, a fabric that has low water retention after dehydration, and a fabric that has both of these properties. Produces excellent fiber products that have low water retention after dehydration.

The fabric of the present invention and the textile product using the fabric are excellent in spreading and sucking and dewatering, and also have low water retention after sucking and dewatering.
When the fabric or textile product of the present invention is dehydrated by the spreading and sucking dewatering method of the present invention, the dehydration can be performed in the expanded state, so that large and strong wrinkles are not newly generated on the surface of the fabric or textile product during dehydration. Have
In addition, using a small type of fabric suction and dehydration device, and products and clothes using a low water retention fabric defined in the present invention, it becomes possible to remove moisture and water droplets in the state of use and wearing, Since the fabric after dehydration has low water retention, it has the advantage that it can continue to use products and clothes as it is, and can lead to the provision of new characteristic products and clothes.
The fabric and dehydration method of the present invention is useful not only for the removal of moisture in the general clothing field, but also for the removal of liquids such as urine, body fluids and fluid filth in hospitals and nursing care fields, It can also be used and used effectively for removing urine and fluid waste.

The objects to be removed from the fibers by suction and dehydration / drainage are mainly moisture and urine, one is moisture and urine on the fiber surface, and the other is moisture and urine that has penetrated into the fabric. Moisture and urine on the fabric surface are in the form of water droplets, or are attached in a state of spreading over the entire surface of the fabric. The moisture and urine on these surfaces are in contact with the fibers constituting the fabric surface. When removing moisture and urine, the moisture and urine that are in contact with the fiber are attached by interacting with the fiber by surface tension, so the force required for removal is higher than the moisture and urine that are not in contact with the fiber. Is more necessary.
Most of the moisture and urine that have penetrated into the fabric are in contact with the fiber, and the moisture and urine interact with the fiber by surface tension, and the force required to remove the moisture and urine is moisture that is not in contact with the fiber. More power is required than the removal of urine and urine and the removal of water adhering to the surface and urine. In particular, moisture and urine that have penetrated into the center are present between the fibers that make up the fabric and are held in the capillaries, and interact with the surface tension with the fibers so as to surround the moisture and urine. More force is needed to remove moisture and urine than the surface. For this reason, in order to make a fabric having excellent sucking and dewatering properties and low water retention after sucking and dewatering according to the present invention, the constituent fibers are acetate fiber, acrylic fiber, nylon fiber, polyester fiber, polypropylene. Hydrophobic fibers such as fibers and vinyl chloride fibers have a lower binding property between water and urine and fibers than hydrophilic fibers such as rayon fiber and cotton fiber, and are easier to absorb and remove moisture and urine. preferable.
This inherent property of the fiber surface can be changed by various fiber processing means such as water repellent processing, so that it can be improved to a more preferable property of hydrophobicity by processing and applied to the present invention. Since hydrophobic fibers can be made more hydrophobic and hydrophilic fibers can also be made hydrophobic, a hydrophobic processing method such as water repellent processing is a preferred processing method. By selecting the fiber and thread type and selecting the fabric structure, the suction dewatering water retention is 40% or less, or the suction dewatering water retention is 30% or less. It becomes possible to obtain a preferable fabric having a suction dewatering water retention of 10% or less, or 20% or less. When the cloth is dehydrated and spread using an actual machine, the above-mentioned cloth can be reduced to a water retention rate of 10% or less, preferably 5% or less. It becomes possible. In order to facilitate sucking and dewatering, the yarn structure constituting the fabric has a smaller distribution ratio of the capillary structure, which plays a particularly important role among the yarn structures related to moisture retention and retention. In addition, it is preferable that the capillary diameter is large, and that the capillary diameter is not uniform and disordered from the viewpoint of easy removal of moisture. Specifically, the fibers constituting the yarn are longer fibers than short fibers, and there are more types of yarns, the yarn structure can be easily changed by various processing means, the points that can be adjusted, the capillary structure distribution This is preferable in that the configuration can be designed so as to reduce the ratio. For example, change the cross-sectional shape of the yarn, devise the composition ratio of the cross-sectional shape, implement stenosis processing or mixed fiber processing, or consider these combinations to devise ease of removal Is possible and preferred. The use of long fibers is preferable because the ratio of the capillary structure is small and the amount of water retention can be selected. Specifically, in the case of yarns having the same thickness, a yarn having a thick single yarn is preferable from the viewpoint that the distribution amount of the capillary structure can be reduced. From the viewpoint of low water retention, the single yarn thickness is preferably 1 denier or more, and more preferably 2 denier or more. Further, the shape of the filament is preferably a processed yarn type in which crimps are generated and the capillary structure is non-uniform, rather than a linear yarn shape, in that the water retention amount increases but dewaterability is easy. The mixed yarn type is also preferable for the same reason. The yarn composition of the blended yarn was also a blended yarn composed of a combination of filaments having a different cross section than a single filament type blended yarn, a blended yarn of low shrinkage yarn and high shrinkage yarn, and combinations of these. A blended yarn in which a modified cross section and different shrinkage yarn are combined is also preferable in terms of easy removal of moisture and the like. In addition, a combination with a method that makes it difficult to create a capillary structure with a mixing method that changes the supply ratio (overfeed amount) of two types of yarns during mixing is preferable from the viewpoint of easy removal of moisture. It is.
A structure in which the capillary structure is shortened by twisting the yarn and a structure in which the diameter is reduced are preferable from the viewpoint that the length of the capillary structure is shorter, the diameter is reduced, and the water content is smaller than the untwisted yarn and the less yarn. The twist coefficient from this viewpoint is preferably 3000 or more, and more preferably 5000 or more.
Strong twisting (increasing the twisting coefficient) narrows the space between the capillaries and makes it difficult to remove permeated water and urine, but is preferable in that the amount of water retained is reduced. Improvement of the point that is difficult to remove can be improved by making the fiber surface hydrophobic by water repellent treatment or the like and reducing the solid surface tension. Since the interval between the capillaries is narrow, a device for improving the penetration of the processing agent into the narrow interval is important for preferable processing such as water repellent processing. For example, it is possible to exemplify a continuous multi-stage treatment method in which the combined use of the penetrant, the immersion and squeezing of the treatment liquid are continuously carried out, and the batch immersion treatment method in which the immersion and the nip drawing treatment are carried out in a bath. These processing means are preferable for dense fabrics such as twisted yarns and dense fabrics such as high density fabrics.
When a garment is manufactured using a fabric having excellent sucking and dewatering properties, it is preferable to use a fabric having excellent sucking and dewatering properties by 50% or more, preferably 70% or more. As for the structure of the garment having excellent sucking and dewatering properties, it is most preferable to use a fabric having excellent sucking and dewatering properties for any of the outer material, the lining and the intermediate material. Further, it is preferable that each part is connected by a button, a chuck, a tape or the like so that it can be removed, because the sucking and dehydrating operation can be carried out separately by removing the parts.

One of the main constitutions of the present invention is an invention relating to a fabric that is excellent in spreading and sucking and dewatering and having low water retention after dehydration, and a product using this fabric. Excellent suction and dehydration from the fabric means that the fabric is easily dehydrated, that the yarn structure constituting the fabric is a yarn structure yarn that is easy to dehydrate, and that It means that the amount of water is small. As described above in the specific example, the factors relating to the ease of moisture removal are influenced by physical factors such as the fiber yarn structure, particularly the capillary yarn structure. If the structural structural factors are the same, the fiber surface properties, particularly the fiber surface tension (solid interfacial tension) are greatly affected, and the yarn made of fibers having a solid interfacial tension that is less hydrophobic than the solid interfacial tension that is highly hydrophilic The fabric used is preferable because moisture is easily removed. In this case, hydrophobic processing of the fiber surface is a preferable processing method. Even if the water retention amount is originally large, a fabric that can be easily removed by the suction and dehydration operation or a fabric that originally has a small water retention amount can be a fabric having excellent suction and dewaterability. Hydrophobic processing of the fiber surface is a preferable processing method as a means for reducing the water retention amount. As described above, hydrophobic processing of fibers is preferable as a processing method for improving suction and dewatering properties. Hydrophobizing processing of hydrophilic fibers, and one hydrophobic processing of hydrophobic fibers is a water retention value of suction dehydrating and suction dehydrating properties. Make it smaller. This is a preferred processing method because it reduces the amount of water retained and facilitates spreading and suction dehydration. Specifically, fiber processing using silicone resin, polyethylene resin, etc., and hydrophobicity of fibers in resin processing, and water-repellent processing (hydrophobization processing) of fibers by water-repellent processing using water-repellent agents, Since the solid interfacial tension on the fiber surface is reduced by hydrophobization, it can be exemplified as a preferred processing method. Further, a waterproof processed cloth obtained by impregnating a fiber with, for example, a urethane-based resin or an acrylic resin, or laminating a waterproof urethane-based resin film or a polytetraethylene-based resin film on the back surface of the cloth. Can prevent water from penetrating into the fabric, or can reduce the water retention amount. Therefore, it is a preferable processing method because the amount of moisture removed from the inside of the fabric is reduced, and only the removal of moisture mainly attached to the surface is required. Furthermore, it is possible to reduce the volume ratio of the capillary structure by partially infiltrating these resins into the fabric, which is a preferable processing method in terms of reducing the water retention amount. By applying these waterproofing processes to a low water retention fabric that sucks out and has excellent dewaterability, a more favorable effect can be obtained synergistically (a synergistic effect that reduces water retention and makes the structure easy to dehydrate). This is preferable. Uses a preferred yarn composition, adopts a preferred hydrophobizing method, and is excellent in spreading and sucking dewaterability obtained by waterproofing. Further, waterproof fabrics are used not only in the field of sports clothing and uniform clothing, It can be widely applied to products, especially sheets and bed cover products in the nursing field. In this case, since penetration of moisture, urine, liquid fluid filth, etc. into the back surface can be prevented, this is a preferred fabric for the present invention and a preferred application example. The waterproofness of the fabric for preventing penetration into the back surface is preferably 300 mm or more, more preferably 1000 mm or more. A cloth having a waterproof polyurethane-based resin coated on the back surface, a cloth laminated with a waterproof polyurethane-based film or a polytetrafluoroethylene-based film and having a waterproof property of 300 mm or more, preferably 5000 mm or more. It is most preferably available for use.
In order to create a fabric with excellent spreading and sucking and dehydrating properties that can more easily suck and remove moisture that has penetrated inside the fiber, the above-mentioned hydrophobic processing and water repellent processing can be applied evenly to the constituent fibers inside the fiber. It is preferable to implement. This is particularly important in the case of a dense fabric or a fabric using a dense yarn structure (for example, a strong twisted yarn). A processing method for improving the penetration of the hydrophobizing agent or water repellent into the fabric is preferable for uniformly processing the inside of the fiber constituting the fabric and the center of the cross section of the fabric. For example, when padding a fabric with a hydrophobizing agent or water repellent, padding is performed using a penetrant, and padding treatment (immersion and mangle squeezing) is repeated multiple times using a continuous treatment method. In a liquid containing a hydrophobizing agent or a water repellent, for example, a processing means such as repeating a nip and an impregnation treatment by a batch processing method using a washing machine, extending an impregnation time, etc. This is a preferable processing means in order to make the effect sufficiently effective. When using a washing machine, there is less processing spots in that the spreading type washing machine that treats the fabric in the expanded state does not cause wrinkles on the fabric surface than the rope type washing machine that processes the fabric in the form of a rope. In this respect, it is preferable in that the amount of the treatment liquid can be reduced and it is economical.
Particularly useful for fabrics with a dense fiber structure, particularly for fabrics such as high-density fabrics with a large total cover factor, such as high-density fabrics with a total cover factor of warp and weft of 1000 or more, preferably 1500 or more. Is the method. Furthermore, although it is described that it is effective when the woven fabric is dense, even when the fabric is not dense, the yarn constituting the fabric is strongly twisted yarn (twisting coefficient is 3000 or more), for example, Especially when the single yarn constituting the yarn is dense, the padding treatment (immersion and mangle squeezing) is repeatedly performed several times, and the nip and impregnation method is repeatedly performed in the liquid. Preferably, it is a preferable processing means (continuous processing type multi-stage processing, batch processing type repeated nip impregnation processing) for reducing the water retention of the fabric and facilitating removal. In view of this, a dense fabric using dense yarn is preferable because it is most effective.
A fabric having a small proportion of capillaries that play a role of water retention in the yarn configuration of the fabric is preferable for the present invention. However, a structural yarn having a small capillary diameter, for example, a yarn having a twist coefficient of 3000 or more, preferably 5000 or more was used. When the above-mentioned multi-stage treatment is performed on the fabric, not only the water retention becomes particularly small, but also the water retention measured in the present application can be set to a value smaller than 5%, so that the fabric does not feel wet. Was confirmed in the Examples. Furthermore, as a result of applying the hydrophobizing agent to the inside of the fabric by performing this multi-stage processing and repeated nip impregnation processing, even if the surface is soiled and the water repellency is deteriorated, it is scraped off by washing or friction. However, the internal hydrophobizing agent is not affected by these effects, and as described above, the water leakage function (water leakage performance) can be greatly improved in addition to the low water retention, easy dehydration, and low water holding performance. all right. It was clarified in the examples that this performance was improved. Needless to say, the time to water leakage, which is an evaluation standard for water leakage, varies greatly depending on the amount of water (water pressure) charged onto the fabric and the degree of density of the fabric. This improvement in water leakage function (water leakage performance) can add new functions to tents, work clothes, products used outdoors, such as hats for fishing, golf wear, and mountain wear.
By selecting the yarn configuration, the fabric configuration, and the processing means, it is possible not only to produce a fabric excellent in spreading and sucking and dehydrating properties that does not form wrinkles on the surface of the present invention, but also to reduce the water retention rate to 5% or less. A fabric having a water retention rate of 5% or less leads to provision of a new garment that can be worn only by centrifugal dehydration after washing without feeling wet. The generation of wrinkles during washing is inevitable, but the point of being able to provide a fabric with a low water retention rate equivalent to normal washing and washing and dehydration after dehydration is that thermal drying is not necessary or necessary in addition to the advantage that it can be worn only by dehydration It can also lead to the provision of minimal energy-saving fabrics. The above-mentioned multi-stage processing, or nip and impregnation, are applied to a fabric composed of a high-density fabric having a cover factor of 1000 or more and a woven or knitted fabric using a hydrophobic long-fiber twisted yarn having a twist coefficient of 3000 or more, preferably 5000 or more. In the fabric subjected to the batch processing repeatedly performed in step 1, a preferred dewatering water retention rate of 20% or less and a suction dehydration water retention rate of 10% or less can be obtained. In the ideal case shown in the examples as an example, it can be said that this is a preferable combination that makes it possible to make the sucked and dehydrated water retention rate 1% or less.

In order to suck out and dehydrate moisture in a state where the fabric is spread, the surface of the fabric is scanned with a vacuum cleaner having normal moisture and moisture absorption capability. The fabric surface mentioned here is an expression including both the front surface and the back surface constituting the fabric. As a specific example of the vacuum cleaner, a vacuum suction type vacuum cleaner using a vacuum pump can be exemplified.
These vacuum cleaners usually take out moisture and the like by suction force, and the removable fabric is a system that removes moisture with the movement of air, so moisture that has penetrated inside is also removed. Cheap. Low-breathable high-density fabrics, fabrics with low breathability such as coatings and laminated fabrics, and soft fabrics, when the suction force is increased, the fabric itself is sucked, causing wrinkles in the fabric, and for removing moisture It is easy to cause troubles because the surface of the surface cannot be scanned. Traditionally, vacuum cleaners have been used to remove moisture spilled on the carpet, etc., but the carpet is thick and has a large fabric weight and is usually coated with a resin as the backing. Because it is hard, there is no problem of being sucked into the suction port of the vacuum cleaner. Further, the carpet surface has large irregularities, and an air passage is secured between the suction port and the carpet, so that the carpet is not sucked.
On the other hand, the fabric of the present invention is soft and lightweight (usually 400 g / m 2 or less) used for personal items such as clothes and apparel, clothes such as clothes, bed covers and sheets, and is thin and soft compared to carpets. In addition, since the surface is flat, it may be sucked into and sucked into the suction port. In the case of sticking, especially in the case of a fabric with low air permeability, it sticks to the suction port, and the moisture removal operation itself by scanning the fabric surface of the suction port of the moisture removing machine cannot be performed. In such a case, the suction port can be made smaller, cut into the periphery of the suction port, or irregularities can be created to improve the shape of the suction port so that air passages are secured to prevent the fabric from sticking. By doing so, the existing built-in vacuum cleaner can be preferably used. Since the moisture removing function vacuum cleaner having a suction port having such a shape that secures an air passage can smoothly perform moisture removal scanning on the surface of the fabric, it is a moisture removing cleaner having a preferred suction port that can be used in the practice of the present invention. is there.
Since the moisture removal efficiency decreases when the suction port is made smaller, the size of the suction port is secured, and the suction port is covered with a net or knitted fabric made of a grid-like or net-like thick thread, or a metal mesh with a coarse mesh. The suction-type moisture removal cleaner having the suction port is also a moisture removal cleaner having a preferred suction port because an air passage can be secured and the moisture removal operation by scanning the fabric surface of the suction port can be performed smoothly.
In this way, the vacuum cleaner's suction port is covered with a net or knitted fabric made of a thick grid or mesh thread, or a metal mesh with a coarse mesh so that it cannot be sucked in. If the surface of the fabric is scanned, it is possible to avoid the trouble of the fabric being sucked into the suction port and efficiently remove the moisture from the fabric, which is a preferable moisture removal method.
When removing moisture and water droplets from a flat, large surface area fabric using a normal vacuum cleaner, a net-like net or wire net made of wire or plastic that is hard to deform and hard on the fabric surface Since the trouble due to the fabric being drawn into the suction port is solved by disposing between the fabric and the suction port of the vacuum cleaner, this is a preferable method for efficiently removing moisture from a wide area of fabric.
In the invention of the present application, a vacuum cleaner having a normal moisture absorption capability can be used, but a moisture removal vacuum cleaner that absorbs moisture while blowing a gas such as air is used for the purpose of improving the moisture absorption capability. It can be used in an applied manner. (Built-in Moisture Absorbing Vacuum Cleaner) If the air is heated, moisture can be absorbed more efficiently, which is preferable. The main purpose is to remove moisture, but a moisture removal vacuum cleaner that absorbs moisture while spraying moisture for the purpose of removing dirt, or after spraying moisture, and a head that has both moisture spraying and suction functions. Other moisture removal vacuum cleaners are also available. In order to further improve the dirt removal function, use a moisture removal cleaner that sucks up moisture while spraying water containing a stain remover itself or detergent, or after spraying water first. Of course, it can also be implemented in an applied manner. Furthermore, in an air blowing type moisture suction cleaner, it is of course possible to carry out a more efficient moisture removing machine by blowing hot air. In a moisture removal vacuum cleaner using hot air in combination, if suction removal is performed while pressing the fabric portion, not only new wrinkles will be generated, but also moisture removal while stretching the wrinkles generated before moisture removal will be possible. This is a preferred method of utilization that can make use of the features of the present invention and can further stretch the koji.
At this time, by making the suction port material a suction port using a large material with a specific heat of 2 or more, preferably 4 or more, the heat capacity becomes large, so not only water can be sucked and removed while pressing, When applied as a water removal vacuum cleaner nozzle after washing, it is possible to reduce the wrinkles generated before water removal and to remove the wrinkles, so that it can be a suction dehydration type water removal vacuum cleaner having a preferable suction port.
In the case of using a detergent or stain remover, it is necessary to sufficiently spray moisture so that the detergent or stain remover does not remain on the fabric or product. If these chemicals remain on the fabric, it is important to complete the removal so as not to remain because the water absorbability is increased and the water removability is inhibited in the next use. It is also important from the viewpoint of skin safety. When using a vacuum cleaner to remove moisture, the case of using air, hot air, water, detergent, etc. in combination as described above is exemplified, but using antibacterial agents, deodorants, water repellents, etc. in combination It can be used in combination according to the purpose within the range of application of a vacuum cleaner whose main purpose is moisture removal.
The moisture removal ability of a vacuum cleaner with a moisture suction function is affected by the suction force of the cleaner, but if the suction force is too large, as described above, the fabric or product of the present invention will become a trouble that will be sucked, so the suction force is adjusted accordingly. A possible type of moisture removal vacuum cleaner is preferred.

The physical property values described in the present invention were evaluated by the following methods.
Moisture charged into and absorbed by the fabric is absorbed by the fiber structure constituting the fabric or remains on the fabric, but how much this moisture remains after the suction operation to keep water inside the fabric. The degree was evaluated as the suction dehydration water retention rate as follows.
A fabric having a diameter of 10 cm to be arranged in a funnel part of a bifnel funnel, model number AF3 (inner diameter: about 10 cm, number of holes: 271, hole diameter: about 1.55 mm) handled by ASONE is prepared in a filter bottle. After measuring the weight W0 of this fabric, it is installed in the funnel. Suction filtration is performed immediately after 100 cc of water is injected thereon. For suction, a vacuum aspiration operation is started using a ULVAC portable aspirator (MDA006) and suction is performed for 1 minute. The ultimate pressure reduction of MDA006 is 6600 Pascal according to the catalog description.
After suction filtration, the fabric is taken out and the weight W1 of the fabric is measured. The suction dewatering water retention (suction dehydration water retention rate) is a value calculated by the following one formula.
(W1-W0) / W0 * 100 (1)
At the time of measurement, a polyester monofilament mesh fabric (T120-55) having a wire diameter of 55 microns manufactured by Yamani Co., Ltd. was arranged for the purpose of making suction uniform between the funnel and the cloth foil.
Draw out the proportion of moisture that is present on the fabric surface and in the interior and remains in the fiber structure inside the fabric without being able to suck out and dehydrate after the suction and dehydration operation. The dehydration water retention rate was measured as follows.
After 5 cc of water is dispensed onto the fabric fixed with a pin and allowed to stand for 5 minutes, the vinyl tube (inner diameter 9 mm) of the Nutsche connection portion is removed from the Nutsche, the tip of the rubber tube is applied to the fabric, and the wet portion is scanned. And suck the water. Carry out three times at a scanning speed of about 3 m / min. Thereafter, the scanning portion is cut into a size of 10 cm * 10 cm, and the weight W2 is measured. The dough weight after drying W0 is measured, and the value calculated by the following two formulas is used as the suction dehydration water retention rate. When evaluating a hydrophobized fabric, an aqueous solution containing 0.1% of a liquid attack (manufactured by Kao Soap Co., Ltd.) is used instead of water.
(W2-W0) / W0 * 100 (2)
In order to prevent the fabric from sticking to the tip of the rubber tube, the surface of the rubber tube is coated with the mesh fabric (T120-55), and the fabric is fixed so that it does not peel off by suction with a pin. Suction removal was performed.
Measurement of fabric water repellency as an index that assumes the proportion of the amount of moisture remaining in the fiber structure constituting the fabric even after centrifugal dehydration after washing at home is performed as follows.
After immersing the fabric (weight W0) in an aqueous solution containing 0.1% liquid attack (made by Kao Soap Co., Ltd.) for 30 minutes, centrifugal dehydration is carried out for 10 minutes in a dehydration tank of a washing machine (model number PS-513, manufactured by Hitachi). The weight W3 of the fabric is measured, and the value calculated by the following three formulas is calculated as the fabric water repellency.
(W3-W0) / W0 * 100 (3)
The evaluation test for evaluating the practical value of the invention product was performed with a suction dehydration cleaner (EVC-550) manufactured by Aqua System Co., Ltd., and was calculated as an actual dehydration water retention rate by the suction cleaner. Suction was performed directly using a soft vinyl chloride tube nozzle with a core wire having an inner diameter of 32 mm. The ultimate vacuum of this EVC-550 is 210 Pascal according to the catalog description.
After 5 cc of water is administered onto the cloth fixed with a pin and left to stand for 5 minutes, the portion where water droplets adhere and the portion that has penetrated are scanned from the lower side five times (about 90 seconds) by the vacuum cleaner. Thereafter, the scanning portion is cut into a size of 10 cm * 10 cm, and the weight W4 is measured. The dough weight W0 after drying is measured, and the value calculated by the following four formulas is used as the actual machine suction and dewatering retention rate. When evaluating a hydrophobized fabric, an aqueous solution containing 0.1% of a liquid attack (manufactured by Kao Soap Co., Ltd.) is used instead of water.
(W4-W0) / W0 * 100 (4)
The waterproof property specified in JIS described below is a method for evaluating the waterproof function of a fabric in a very short measurement time. When a fabric is used in practice, waterproofing may be required for a long time. As an index for evaluating the waterproofness over a long period of time, instead of the waterproof evaluation of JIS regulations, the water leakage was measured as follows. A dough is loosely fixed on a 200 cc plastic beaker, and 100 cc of water is poured thereon. Maintain water at a height that does not spill from the beaker. Measure the time and days until water leaks from the dough. For example, if 100 cc is injected and the water leaks after 1 day, the water leakage function of the fabric is expressed as 100 cc * 1 days of water resistance.
Ordinary waterproofness was measured by the method described in JIS L 1092 water resistance test (hydrostatic pressure method) method A (low water pressure method) or method B (high water pressure method).
The water repellency was measured by the spray method described in JIS L 1092.
The air permeability was measured by the method described in JIS L 1096A method (Fragile method).
Laundry was carried out by the method described in JIS L 0217 103 method.
The twist coefficient was calculated by the following formula.
Twist factor = T x (denier) ^1/2
Here, T is the number of twisted yarns (T / m), and D is the total fineness (denier) of the yarn.
The total cover factor was calculated by the following formula.
Total cover factor = (DWp) ^1/2 × MWp + (DWf) ^1/2 × MWf
However, DWp is the total warp fineness (denier), MWp is the warp weave density (main / 2.54 cm), DWf is the total weft fineness (denier), and MWf is the weft weave density (main / 2.54 cm).

A warp and weft yarn of 50 denier, 144 filaments and a warp mat with a twist of 1500 times / meter was dyed in a normal dyeing process to obtain a blue dyed product. The warp density of the dyed product was 268 yarns / inch, and the weft density was 114 yarns / inch. The total cover factor was 2701 and the yarn twist coefficient was 10607.
The dyed woven fabric was dipped and mangled ten times repeatedly with a water repellent formulation liquid having the following formulation, and then dried and heat-treated by ordinary methods to prepare the product 1 of the present invention. A similar woven fabric was dipped and mangled once with the above treatment solution in the usual manner, and then dried and heat treated in the usual manner to produce Invention Product 2.
The physical properties of Invention Products 1 and 2 are shown in Table 1. The fabric weights of the inventive products 1 and 2 were 127 and 128 g / m ² , respectively.
