Description

TECHNICAL FIELD

The present invention relates to a woven and knitted fabric subjected to mold processing. In particular, the present invention relates to a woven and knitted fabric having imparted thereto satisfactory mold processability through use of heat-fusible polyurethane elastic filaments.

BACKGROUND ART

There is known an approach to imparting mold processability to a woven fabric or a knitted fabric by providing the fabric with thermoplastic fibers. JP 2001-98446 A (Patent Literature 1) discloses a technology for mold processing, involving using polyurethane elastic filaments each having a high heat setting rate. JP 2006-225817 A (Patent Literature 2) discloses a technology for mold processing, involving using polyurethane elastic filaments and nylon fibers.

However, it cannot be said that any of the technologies is sufficient in actual mold processability. In addition, according to such technology, the mold processing is performed by applying excessive heat, and hence thermoplastic fibers of a face yarn harden. As a result, the woven fabric or knitted fabric to be obtained is poor in fabric feeling and takes on a shine in some cases.

In the technology described in Patent Literature 2, it is assumed that, when a woven and knitted fabric containing elastic fibers (polyurethane elastic filaments) is subjected to the mold processing, synthetic fibers (e.g. nylon or polyester) having high thermoplasticity are mixed and used in the face yarn and the processing is performed at high temperature. The reason for this is to set the synthetic fibers mixed and used at a certain rate by heat, thereby reducing a shrinking force of the polyurethane elastic filaments. When such high-temperature processing is assumed, it is substantially impossible to subject a fabric mainly containing natural fibers or regenerated fibers having no thermoplasticity to the mold processing.

Further, in the case of the high-temperature processing as described above, when a fabric after dyeing processing is subjected to the mold processing, heat at the time of the mold processing causes a dye to sublime. Hence, a color of the processed part changes and fastness is deteriorated in many cases. Thus, there is provided only a product having low commercial product performance. In addition, in the case of the high-temperature processing, the fabric undergoes yellowing owing to the heat, and hence the processing cannot be employed for light-colored fabric. Therefore, only part of the fabric subjected to the mold processing may be cut out and used, but it is impossible to subject only a desired part of the fabric as a whole to molding and then use the whole as a product.

In addition, in the case where a fabric mainly containing the natural fibers or the regenerated fibers and containing no polyurethane elastic filaments is subjected to the mold processing, it is necessary to apply heat at 200° C. or more. This results in yellowing of the natural fibers or the regenerated fibers. On the other hand, when the polyurethane elastic filaments are used in combination with the natural fibers or the regenerated fibers, elasticity of the polyurethane causes shrinkage. Hence, it is practically impossible to subject a fabric using the natural fibers or the regenerated fibers and the polyurethane elastic filaments to the mold processing.

JP 2008-138298 A (Patent Literature 3) discloses a technology for mold processing, involving using a yarn that is excellent in low-temperature setting property. Although this yarn provides excellent formability from a low temperature region, a proper range of a processing temperature is narrow. Therefore, there are many limitations in a dyeing processing step in preparation of a base fabric to be subjected to the mold processing and fibers usable therewith are limited. In addition, when a heat treatment temperature, the mold processing temperature, or the like is shifted to high temperatures in the preparation of the base fabric, there arises a problem in that breakage of the polyurethane elastic filaments occurs, for example. Owing to the breakage of the polyurethane elastic filaments, a fabric after forming is liable to lose shape, has no stretching property, and is inferior in appearance as well.

The applicant of the present application has proposed a technology involving using heat-fusible polyurethane elastic filaments in a woven and knitted fabric containing polyurethane elastic filaments, thereby trying to achieve heat setting property, misalignment prevention, and the like (Patent Literatures 4 and 5). However, this technology achieves only misalignment prevention and fray prevention.

DESCRIPTION OF EMBODIMENTS

Hereinafter, the present invention is described in more detail.

A woven and knitted fabric of the present invention includes a yarn containing elastic fibers and at least one kind of non-elastic fibers, the woven and knitted fabric being subjected to mold processing. The elastic fibers contain heat-fusible polyurethane elastic filaments each having a fineness of 17 dtex or more, and at least part of the heat-fusible polyurethane elastic filaments is heat-fused in the woven and knitted fabric. The woven and knitted fabric is subjected to the mold processing at 120 to 190° C.

As the elastic fibers, elastic fibers well known in the art may be used. The elastic fibers are preferably polyurethane elastic filaments. As the polyurethane elastic filaments, polyurethane elastic filaments well known in the art may be used.

The heat-fusible polyurethane elastic filaments to be used in the present invention are not particularly limited as to their composition, production method, and the like as long as the heat-fusible polyurethane elastic filaments are polyurethane elastic filaments having such heat-fusion property as to allow the filaments at crossover points therebetween to be heat-fused each other.

The heat-fusible polyurethane elastic filaments may be obtained by, for example: (1) a method involving allowing a polyol to react with an excess molar amount of a diisocyanate to produce a polyurethane intermediate polymer having isocyanate groups at both ends, allowing the intermediate polymer to react with a low-molecular-weight diamine or low-molecular-weight diol having active hydrogen capable of easily reacting with the isocyanate groups of the intermediate polymer in an inert organic solvent to produce a polyurethane solution (polymer solution), and then removing the solvent to form the solution into a string; (2) a method involving solidifying a polymer obtained through a reaction among a polyol, a diisocyanate, and a low-molecular-weight diamine or a low-molecular-weight diol, dissolving the solidified polymer in a solvent, and then removing the solvent to form the solution into a string; (3) a method involving forming the solidified polymer into a string by heating without dissolving the polymer in a solvent; (4) a method involving allowing the polyol, the diisocyanate, and the low-molecular-weight diol to react with each other to produce a polymer, and forming the polymer into a string without solidifying the polymer; or (5) a method involving mixing the polymer or polymer solution obtained in each of the methods, and then removing the solvent from a mixed polymer solution to form the mixed polymer solution into a string.

The heat-fusible polyurethane elastic filaments may be preferably obtained by a method involving melt spinning the following polymer. The polymer is obtained by allowing a prepolymer (A) having isocyanate groups at both ends, which is obtained through a reaction between a polyol and a diisocyanate, to react with a prepolymer (B) having hydroxyl groups at both ends, which is obtained through a reaction among a polyol, a diisocyanate, and a low-molecular-weight diol. This method is suitable from an economic or environmental viewpoint as well because the method does not involve recovering a solvent.

In addition, a composition including 50 mass % or more of a polyether polyol in the polyol component in the raw materials is preferably adopted. With such composition, a polymer excellent in alkali resistance can be obtained, and hence limitations on conditions for the dyeing processing of fibers to be used in combination can be reduced.

With regard to the heat-fusion performance of each of the heat-fusible polyurethane elastic filaments to be used in the present invention, a heat-fusion force is preferably 0.15 cN/dtex or more, and more preferably 0.30 cN/dtex or more. If the heat-fusion force is less than 0.15 cN/dtex, satisfactory mold processability may not be obtained.

For example, in the case of a knitted fabric, the heat-fusion force is measured in the following manner.

The knitted fabric is cut in a course direction, and an unraveling tension is measured for heat-fusible polyurethane elastic filaments or a yarn containing heat-fusible polyurethane elastic filaments, the fibers or yarn being knitted within the cut portion. An unraveling speed is set at 100 mm/min, and an average unraveling tension during a period of 1 minute is measured. When continuous unraveling is possible, average unraveling tensions are measured before and after heat treatment. Then, the average unraveling tension (cN) after the heat treatment is divided by the initial fineness (dtex) of the heat-fusible polyurethane elastic filaments to determine the heat-fusion force (cN/dtex). It should be noted that the heat-fusion force is so strong in some cases that the unraveling of the heat-fusible polyurethane elastic filaments is difficult. The heat-fusion force in those cases, which is needless to say 0.15 cN/dtex or more, is judged as “complete fusion.”

The fineness of each of the heat-fusible polyurethane elastic filaments to be used in the present invention is, from the viewpoint of the fabric feeling of the woven and knitted fabric to be obtained, preferably 17 dtex or more, more preferably 22 to 311 dtex, still more preferably 28 to 156 dtex. If the polyurethane elastic filaments are thinner than 17 dtex, the area of a part to be heat-fused (i.e., a heat-fusion area), which is a crossover point between the polyurethane elastic filaments in contact with each other, decreases. As a result, the setting property of the fabric decreases, and hence desired moldability may be difficult to obtain. An upper limit for the fineness is not particularly limited. However, when the fineness of the fibers is large, the fabric becomes like rubber, and hence there is such a general tendency that fibers having small fineness are preferred.

As the heat-fusible polyurethane elastic filaments to be used in the present invention, a yarn formed of only the heat-fusible polyurethane elastic filaments (bare yarn) may be adopted, or a composite yarn such as a covered yarn (a single covered yarn or a double covered yarn), a double twist yarn, or an air interlaced yarn may be adopted. Of those, a covered yarn is preferred because the heat-fusible polyurethane elastic filaments may be placed at the center of the composite yarn, and the coverage of the heat-fusible polyurethane elastic filaments can be easily controlled and uniform covering can be achieved.

When the composite yarn (e.g., covered yarn) is used as the heat-fusible polyurethane elastic filaments, non-elastic fibers for covering the heat-fusible polyurethane elastic filaments are not particularly limited. As such non-elastic fibers, there may be used, for example: natural fibers such as cotton, hemp, wool, and silk; regenerated fibers such as rayon, cupra, and polynosic; semi-regenerated fibers such as an acetate; and chemical synthetic fibers such as nylon, polyester, acryl, and polypropylene.

In the woven and knitted fabric of the present invention, as described above, the elastic fibers in the fabric are preferably polyurethane elastic filaments. In addition, the mixture ratio of the polyurethane elastic filaments in the fabric is preferably 5% or more, more preferably 8% or more, and still more preferably 10% or more. An upper limit for the mixture ratio of the polyurethane elastic filaments is preferably 35%, and more preferably 25%. In addition, the mixture ratio of the heat-fusible polyurethane elastic filaments in the polyurethane elastic filaments is preferably 50% or more, more preferably 80% or more, and still more preferably 100%. When the mixture ratio of the heat-fusible polyurethane elastic filaments falls within such range, a heat-fusion area between the polyurethane elastic filaments can be increased to provide a fabric having higher formability.

As the non-elastic fibers for constituting the woven and knitted fabric of the present invention, non-elastic fibers well known in the art may be used. Specific examples of the non-elastic fibers include those described above for the case where a composite yarn is used as heat-fusible polyurethane elastic filaments.

The woven and knitted fabric subjected to mold processing of the present invention is produced in substantially the following manner.

First, at least one kind of the non-elastic fibers and the elastic fibers containing a bare yarn of the heat-fusible polyurethane elastic filaments or a composite yarn containing the heat-fusible polyurethane elastic filaments are prepared. The elastic fibers and the non-elastic fibers are used to provide a woven and knitted fabric through weaving, knitting, or the like. The fabric then is subjected to heat setting or heat treatment of mold processing, thereby heat-fusing at least parts of the heat-fusible polyurethane elastic filaments with each other.

The woven and knitted fabric of the present invention may be constructed of a woven fabric or a knitted fabric depending on its applications. For example, when the woven and knitted fabric of the present invention is constructed of the woven fabric, any one of plain weaving, twill weaving, satin weaving, and the like may be employed. Further, when the knitted fabric is used, a well-known knitting method such as warp knitting or weft knitting may be appropriately employed.

For example, when the woven and knitted fabric of the present invention is constructed of the knitted fabric, a knitted fabric obtained by plating knitting the heat-fusible polyurethane elastic filaments and at least one kind of non-elastic fibers is preferred. The knitted fabric obtained by the plating knitting allows the heat-fusible polyurethane elastic filaments to be stably heat-fused with each other at a crossover point of knit stitches at the time of heat treatment, and thus the knit stitches can be fixed.

As a weft knitted fabric to be used in the present invention, plain knitting, rib knitting, double knitting, or the like may be appropriately employed. Plain knitting is preferred because a fabric is finished into a thin product and the fabric undergoes no significant change in shape of each of a needle loop and a sinker loop even when the fabric is partially stretched in molding.

The draft rate of the heat-fusible polyurethane elastic filaments at the time of the weaving or knitting of the fabric is preferably 1.0 to 3.6 times, and more preferably 2.0 to 3.0 times.

Next, the fabric is processed through general steps. For example, a series of processing steps “refinement-bleaching-presetting-dyeing-final setting” is performed. Then, the processed fabric is subjected to mold processing. The mold processing is preferably performed at a temperature of 120 to 190° C. Through the mold processing at such temperature, the woven and knitted fabric of the present invention subjected to the mold processing after dyeing processing may have a color change resistance grade of Grade 3 or more. If the temperature is less than 120° C., formability may be insufficient. If the temperature is 190° C. or more, a face yarn undergoes yellowing or hardening, and hence the fabric may not clear the color change resistance grade. It should be noted that the color change resistance grade may be determined according to JIS L0804.

Treatment of the mold processing is typically performed as follows. Further, a forming rate is calculated as follows.

A spherical jig made of iron (diameter: 105 mm, weight: 1.5 kg) as a mold processing jig is heated with a dryer to a given processing temperature. When the temperature of the jig becomes stable, the jig is pressed against a fabric, which is unstretched and left to stand still, for 1 minute to form the fabric. In this case, the jig is caused to sink by 70 mm. After having been left to stand still at ordinary temperature for 30 minutes, the depth of a depression in the fabric is measured, and the ratio of the measured value to the depth at the time of the forming, i.e., 70 mm is calculated, which is defined as the forming rate.

The forming rate of the woven and knitted fabric of the present invention is preferably 20% or more, more preferably 25% or more, and still more preferably 30% or more. The combination of such forming rate (mold processability) and the excellent color change resistance grade is one of the achievements of the present invention.

Further, Table 3 shows the results of a test performed for confirming the formability of the yarns used. The test was performed by the following procedure.

Plating knitting was performed at a draft rate of 2.0 times using polyester 33T10 filaments for a face yarn, using polyurethane elastic filaments in Table 3 for aback yarn, and using a pantyhose knitting machine (L416/R manufactured by Lonati, kettle diameter: 4 inches, number of needles: 400) to prepare a plain knitted fabric. The fabric was stretched 1.2 times in both warp and weft directions and subjected to heat setting at 150° C. for 60 seconds to provide a base fabric.

As evident from Tables 1 and 2, it can be understood that each example of the present invention is excellent in both forming rate and color change resistance grade. Comparative Examples 1 and 2 were inferior in formability, and Comparative Examples 4 and 5 were inferior in color change resistance. Comparative Example 3 was satisfactory in formability, but breakage of polyurethane elastic filaments occurred. As also evident from Tables 1 and 2, according to the present invention, mold processability can be imparted to even a fabric containing natural fibers or regenerated fibers having no thermoplasticity, and even a woven and knitted fabric containing thermoplastic fibers having low heat resistance, such as nylon or polypropylene, does not show yellowing after processing with the result that a light-colored fabric can also be subjected to mold processing. As a result, satisfactory formability can be imparted to a product required to have shape-maintaining property, such as underwear such as a cup portion of a brassiere, or a hip portion of shorts or a girdle, a knitted fabric for indoor sports such as swimming wear, or a woven fabric for outerwear such as a bottom, and the designing of the product can be performed freely. In particular, the face yarn free of hardening provides good fabric feeling of the fabric and the use of the natural fibers or the regenerated fibers causes no skin disorder such as rash even upon direct contact with a delicate portion of skin. In addition to the field of clothing, a wide range of applications are possible, such as a combination with another material to provide a laminate material having stretching property.

INDUSTRIAL APPLICABILITY

The woven and knitted fabric of the present invention can be suitably utilized in the field of clothing. For example, the woven and knitted fabric can be suitably utilized as underwear such as a cup portion of a brassiere, or a hip portion of shorts or a girdle, a knitted fabric for indoor sports such as swimming wear, or a woven fabric for outerwear such as a bottom. In addition, the woven and knitted fabric of the present invention can also be utilized as, for example, a laminate material having stretching property in other industrial fields.
