Description

  The present invention relates to a napped pile fabric and a method for producing the same, and particularly to a high pile fabric and a method for producing the same.

  Conventionally, napped pile fabric has been known as a fabric having an appearance resembling fur under the names of imitation fur, faux fur, bore and the like. They are made from pile knitted fabrics and pile fabrics. In the case of a knitted pile, knitting is mainly performed by a seal milling machine and a sliver knit machine (circular knitting machine), and in both cases, pile fibers are cut. When knitting with a double raschel machine of a warp knitting machine, knitting is performed by forming the ground texture double and simultaneously tying the binding yarn between the ground textures and cutting the middle of the binding yarn. In the case of the weaving method, velvet looms and moquette looms are used to intertwine the upper and lower ground fabrics and the binding yarn between them, and the upper and lower base fabrics are cut with a knife so that the two fabrics can be made simultaneously. Weaving (Non-Patent Document 1). However, these woven and knitted fabrics have a problem that they have a lot of hair loss. If there is a lot of hair loss, it will stick to the inner garment or drop off on the floor, which will cause poor appearance and hygienic problems.

  In particular, among high pile fabrics among napped pile fabrics, the pile fibers are knitted along the loop of the ground yarn of the knitted fabric, and the friction resistance between the ground yarn and the pile fiber is small, so that the pile fiber can be produced with a small force. There is a problem that the single fiber constituting the pile fiber is easily dropped only by pulling one end of the wire.

  As measures for improvement, there are proposals for mixing low-melting fibers with pile fibers (Patent Document 1), proposals for mixing low-melting fibers with ground yarn constituting the ground structure (Patent Documents 2 and 3), and the like. However, both of these proposals heat the entire fabric at a temperature equal to or higher than the melting point of the low-melting fiber, so that the entire ground texture or the pile fiber is also fused, resulting in a rough texture. is there.

  In order to solve the above-mentioned problems, in the napped pile fabric using specific fibers, only the specific portion is subjected to thermocompression bonding, thereby preventing the pile fibers from coming off without impairing the texture of the napped surface. There is a proposal to provide a fabric (Patent Document 4). However, the proposed pile fabric has room for improvement in that the non-raised surface subjected to thermocompression bonding becomes hard and the fabric is likely to be wrinkled. In apparel and the like, the raised pile fabric with wrinkles has a poor appearance on the raised surface, and the commercial value of the raised pile fabric may be significantly reduced.

  An object of the present invention is to provide a high-pile fabric and a method for producing the same, which keeps the flexibility of the high-pile fabric and prevents the pile fibers from falling out without damaging the texture.

  As a result of intensive studies, the present inventors have found that the above-mentioned problems can be solved by making the non-raised surface of the high pile fabric into a specific configuration, and have completed the present invention. That is, the gist of the present invention is as follows.

One of the features of the present invention includes a ground tissue and a pile fiber that is entangled with the ground yarn constituting the ground tissue and is raised on the raised surface of the ground tissue, and the pile fiber is composed of an acrylic fiber and an acrylic fiber. In a high pile fabric comprising at least one fiber selected from the group, wherein the pile fiber has a softening point lower than that of the fiber constituting the ground texture, the glass transition point is from -100 ° C to 10 ° C on the non-raised surface of the ground texture. Adhesive resin at a temperature of 30 g / cm ² to 300 g / cm ^{2 is} attached, and among pile fibers entangled with the ground yarn constituting the ground texture, at least a part outside the ground yarn constituting the ground texture The pile fiber is pressure-bonded together with the adhesive resin, and the pile fiber raised on the raised surface of the ground tissue is not fused.

  Another feature of the present invention is a high pile product obtained by processing the above high pile fabric.

Another feature of the present invention includes a ground tissue and a pile fiber that is entangled with the ground yarn constituting the ground tissue and is raised on the raised surface of the ground tissue. The pile fiber is an acrylic fiber and an acrylic fiber. Including at least one fiber selected from the group consisting of: the pile fiber has a lower softening point than the fiber constituting the ground tissue, and the pile fiber raised on the raised surface of the ground tissue is not fused. A method for producing a high-pile fabric characterized in that an adhesive resin having a glass transition point of −100 ° C. to 10 ° C. is attached to 30 g / cm ² to 300 g / cm ^{2 on} the non-raised surface of the ground structure, A step of pressure-bonding at least a part of pile fibers outside the ground yarn constituting the ground structure, together with the adhesive resin, among pile fibers entangled with the ground yarn constituting the ground texture. Manufacturing method of high pile fabric It is.

  According to the present invention, it is possible to provide a high-pile fabric that has a good appearance and texture, suppresses hair loss, has a soft non-raised surface, and does not easily wrinkle, and a high-pile product obtained by processing the high-pile fabric. .

It is a schematic diagram for demonstrating the positional relationship of the ground yarn and the pile fiber entangled with the ground yarn in one embodiment of the high pile fabric according to the present invention. It is a manufacturing process figure in one Example of this invention.

  The high pile fabric of the present invention is a high pile fabric including a knitted ground structure and pile fibers that are tangled with the ground yarn constituting the ground structure and are raised on the surface of the ground structure.

  The ground structure used in the present invention is a knitted fabric, and can form a structure excellent in stretchability. In general, knitted fabrics are one or two or more yarns that form a loop, and continue to create the next new loop by hooking on the loop, and then forming the fabric by successively repeating the loop in a plane. is there. Then, weaving knitted fabrics that move in the horizontal direction depending on whether the yarn reciprocates left and right while forming a loop to form a flat fabric or a spiral fabric that forms a tubular fabric, etc. A warp knitted fabric is a fabric in which a number of warp yarns arranged in an orderly manner are connected to each other by adjacent loops to form a fabric. Further, flat knitting, rubber knitting, pearl knitting, and the like are used for flat knitting, and warp knitting includes knitting such as denby knitting, cord knitting, atlas knitting, and chain knitting. As a knitting method constituting the ground structure of the high pile fabric, weft knitted fabric is preferable from the viewpoint of merchantability and productivity.

  In the present invention, the pile fibers may be arranged with respect to the knitted fabric so that the pile fibers are entangled with all the loops constituting the knitted fabric of the ground structure, and among the loops constituting the knitted fabric, the wale direction and / Or you may arrange | position so that it may have the part which the pile fiber does not get entangled in the course direction.

  The fiber constituting the ground yarn is not particularly limited as long as it has a softening point higher than that of a pile fiber described later, and examples thereof include synthetic fibers made of polyester resin such as polyethylene terephthalate, cotton, and the like.

  The pile fiber preferably includes at least one fiber selected from the group consisting of acrylic fiber and acrylic fiber (hereinafter sometimes abbreviated as acrylic (system) fiber). Thereby, a high pile fabric excellent in texture can be obtained. Generally, when a thermoplastic fiber is used as a pile fiber and polishing is performed at a temperature higher than the melting point and softening point of the thermoplastic fiber, the pile fiber on the surface of the high pile fabric is burnt or melted. A high pile fabric having a good appearance and texture cannot be obtained. Further, if polishing is performed at a temperature below the glass transition point of the thermoplastic fiber, the pile fiber on the surface of the high pile fabric will not be crimped, so that a high pile fabric having a good appearance and texture cannot be obtained.

  Pile fiber crimps extend even at temperatures below the melting point. In addition, since the glass transition point of acrylic (system) fiber is about 100 ° C. and the softening point is about 150 to 230 ° C., when acrylic (system) fiber is used for the pile fiber, it is above the glass transition point and below the softening point. Polishing can be performed at a temperature, for example, 100 to 150 ° C. Furthermore, since the crimp of the acrylic (based) fiber tends to be easily stretched as compared with fibers of other materials, a high pile fabric having a good appearance and texture can be obtained.

  The pile fiber is not particularly limited, and synthetic fibers made of polyester resins such as polyethylene terephthalate and polytrimethylene terephthalate and other synthetic fibers can also be used.

  The pile fiber is not particularly limited as long as it is a ground yarn constituting the ground structure and has a softening point lower than that of the fiber constituting the ground yarn, but the difference between the softening point of the fiber constituting the ground yarn and the pile fiber is not limited. Is preferably 10 ° C. or higher, more preferably 20 ° C. or higher, and particularly preferably 30 ° C. or higher. If there is a difference of 10 ° C or more, only the pile fibers arranged outside the ground yarn on the non-raised surface of the above ground structure are thermocompression bonded, and the pile fibers raised on the surface of the above ground structure are thermocompression bonded. It is easier not to do this.

  The pile fiber may be a fiber that is softened at a predetermined temperature, or may be a mixed fiber of fibers that are softened at different temperatures. And when the pile fiber is a mixed fiber of fibers that soften at different temperatures, the fiber that softens at a relatively low temperature is mixed by 20% by weight (wt%) or more, and the fiber that softens at a relatively low temperature It is preferably thermocompression bonded, and more preferably 50% by weight or more is mixed.

  In addition, if the temperature difference between the softening points of the ground yarn and the pile fiber is within the above-mentioned range, the pile fiber that is difficult at a relatively low temperature is not limited to acrylic fiber and acrylic fiber. Synthetic fibers made of polyester resins such as polyethylene terephthalate and polytrimethylene terephthalate and other synthetic fibers can also be used.

  In the present invention, the softening point is a softening temperature before melting or decomposition. For example, the softening point of acrylic fibers is 190 to 232 ° C., and the softening point of acrylic fibers is 150 to 220 ° C. (“Chemical Dictionary”, Kyoritsu Shuppan, pages 727 to 729, published on June 1, 1993, hereinafter “ Literature value ”).

  In the present invention, an acrylic fiber refers to a fiber comprising a polymer obtained by polymerizing a composition containing 85% by weight or more of acrylonitrile. The acrylic fiber includes a polymer obtained by polymerizing a composition containing acrylonitrile in an amount of 35 wt% to less than 85 wt% and other copolymerizable monomers in an amount of more than 15 wt% to 65 wt%. The fiber which consists of.

  Here, the other copolymerizable monomers include vinyl halides and vinylidene halides typified by vinyl chloride, vinylidene chloride, vinyl bromide, vinylidene bromide, allyl sulfonic acid, methallyl sulfonic acid, styrene sulfone. Sulfonic acid-containing monomers represented by acids, isoprenesulfonic acid, 2-acrylamido-2-methylpropanesulfonic acid and the like, and metal salts and amine salts thereof, acrylic acid and methacrylic acid, and lower alkyl esters thereof, N or N, N-alkyl-substituted aminoalkyl esters and glycidyl esters, acrylamide and methacrylamide, and N- or N, N-alkyl-substituted products thereof, carboxyl group-containing vinyl monomers represented by acrylic acid, methacrylic acid, itaconic acid, and the like, and Them Typical examples include anionic vinyl monomers such as thorium, potassium and ammonium salts, cationic vinyl monomers including quaternized aminoalkyl esters of acrylic acid and methacrylic acid, or vinyl group-containing lower alkyl ethers and vinyl acetate. And vinyl group-containing lower carboxylic acid esters and styrene. These monomers can be used alone or in admixture of two or more.

  Among these, it is preferable to use one or more monomers selected from the group consisting of vinyl halides, vinylidene halides and metal salts of sulfonic acid-containing monomers, and selected from the group consisting of vinyl chloride, vinylidene chloride and sodium styrenesulfonate. More preferably, one or more monomers are used.

  As acrylic fiber, it is preferable to use a modacrylic fiber. Modaacryl fiber contains acrylonitrile 35 wt% or more and less than 85 wt%, and contains more than 15 wt% of one or more monomers selected from the group consisting of vinyl chloride and vinylidene chloride and other copolymerizable monomers. A fiber comprising a polymer obtained by polymerizing a composition containing 65% by weight or less.

  The combination of the types of fibers and pile fibers constituting the ground yarn in the present invention is not particularly limited as long as the above conditions are satisfied, but specific examples thereof are shown below.

  For example, when a polyethylene terephthalate (PET, softening point of about 258 ° C.) fiber is used as the fiber constituting the ground yarn, it is preferable to use an acrylic fiber or a mixed fiber of an acrylic fiber and an acrylic fiber as the pile fiber. . As the acrylic fiber, the following fibers can be preferably used.

(1) Vinyl chloride-acrylonitrile fiber (for example, manufactured by Kaneka Corporation, trade name “Kanekaron”, softening point 150 to 220 ° C., literature value)
(2) Vinylidene chloride-acrylonitrile fiber (softening point 150-220 ° C, literature value)
For example, when a cotton (cotton) (no softening point) fiber is used as the fiber constituting the ground yarn, an acrylic fiber is preferably used as the pile fiber. Moreover, as an acrylic fiber, the product name "Exlan K691" (softening point 190-232 degreeC, literature value) by Exlan Co., Ltd. can be illustrated, for example.

  In the present invention, the pile fiber has a softening point lower than that of the fiber constituting the ground yarn as described above, and among the pile fibers entangled with the ground yarn, at least one of the pile fabrics on the non-raised surface of the ground texture outside the ground yarn. The pile fiber of the part is thermocompression bonded, and the pile fiber raised on the raised surface of the ground tissue is not thermocompression bonded. This means is not particularly limited as long as at least a part of the pile fiber outside the ground yarn can be thermocompression bonded, but from the non-raised surface side of the ground tissue, that is, from the non-raised surface side of the high pile fabric, the pile fiber softening point or more, And it is preferable to heat-press at a temperature lower than the softening point of the fibers constituting the ground yarn.

  In the present invention, the outside of the ground yarn on the non-raised surface of the ground structure means the non-raised surface side when the surface where the pile fiber of the high pile fabric is raised is the surface, and is outside the ground yarn. is there. In addition, the pile fiber entangled with the ground yarn may include some fibers that have bite into the ground yarn, but the remaining portion is present outside the ground yarn.

  In the present invention, as described above, at least some of the pile fibers outside the ground yarn are thermocompression bonded. As an aspect in which the pile fibers are thermocompression-bonded, for example, an embodiment in which each of the adjacent pile fibers is connected to each other to form a lump after the heat and pressure treatment described later, An embodiment in which each of the pile fibers in the vicinity of the outermost side of the yarn is connected to each other, and the pile fibers on the inner side are pressed against the ground yarn to form a lump. An embodiment in which unsoftened fibers are connected via softened fibers to form a lump is included, but is not limited thereto. Further, in any of the cases where the thermocompression bonding is performed, as a result of the pressure bonding, the bulkiness of the pile fiber outside the certain ground yarn is smaller than that before the pressure bonding, and the high pile fabric The non-raised surface has a smooth appearance (a state in which the fluffing on the non-raised surface of the pile fiber is significantly reduced).

  Moreover, in the high pile fabric of the present invention, it is sufficient that at least a part of the pile fibers outside the ground yarn is thermocompression bonded as described above. It is preferable that all outer pile fibers are thermocompression bonded.

  In the present invention, a non-raised surface pile fiber is thermocompression-bonded together with an adhesive resin having a low glass transition point, so that a raised fiber fabric having a soft non-raised surface and hardly wrinkled can be obtained.

  In a general method, when manufacturing a napped pile fabric, an adhesive resin is attached to the non-napped surface of the napped pile fabric, and the pile fiber existing on the napped surface is bonded and fixed to the ground yarn. Prevent omissions. At that time, if an adhesive resin having a low glass transition point is used, the non-raised surface tends to be soft, but the effect of preventing hair loss tends to be smaller than when a resin having a high glass transition point is used. .

  In the present invention, since the hot-press treatment is performed after adhering an adhesive resin having a low glass transition point to the non-napped surface of the napped pile fabric, even if an adhesive resin having a low glass transition point is used, The prevention effect is never reduced.

  When non-raised surfaces of napped pile fabrics using thermoplastic fibers as pile fibers are hot-pressed at a temperature above the melting point or softening point of the thermoplastic fibers without adhering adhesive resin, they are present on the non-raised surfaces. Thermoplastic fibers are thermocompression bonded into a single sheet. Furthermore, since the glass transition point of a general thermoplastic fiber is not lower than normal temperature (the glass transition of acrylic fiber and acrylic fiber is about 100 ° C.), when formed into a sheet, it feels very hard at normal temperature.

  In the present invention, for the above phenomenon, a hot pressure treatment is performed after an adhesive resin having a glass transition point lower than room temperature is attached to the non-raised surface of the raised pile fabric. By this, since the adhesive resin with a low glass transition point enters between the pile fibers existing on the non-raised surface, the probability that the pile fibers are directly bonded to each other is reduced. Since the adhesive resin having a low glass transition point has flexibility even at room temperature, the non-raised surface of the raised pile fabric feels soft even after hot pressing.

  However, when a resin having a glass transition point higher than room temperature is used as an adhesive resin, a resin having a glass transition point higher than room temperature feels hard at room temperature, so the non-raised surface of the napped pile fabric after hot pressing also feels hard. It is done.

  Moreover, when the non-raised surface of the napped pile fabric becomes soft, wrinkles are less likely to occur on the napped pile fabric, and the merchantability increases.

  The adhesive resin is not particularly limited, but latex, emulsion, dispersion, etc. of SBR resin, NBR resin, vinyl acetate resin, acrylic ester resin, and polyurethane resin should be used. Can do. These adhesive resins may be used alone or in combination of several kinds. As the adhesive resin, a latex of an acrylic ester resin can be preferably used.

The amount of the adhesive resin impregnated may be about 30 to 300 g / m ^{2 in} order to sufficiently impregnate the adhesive resin between the pile fibers present on the non-raised surface of the napped pile fabric. In addition, if adhesive resin is attached to the non-raised surface of the raised pile fabric at about 30 to 300 g / m ² , the pile fiber is fixed to the ground yarn, and the manufacturing process such as the brush process and the polishing process until the hot pressing process is performed Since the ground structure of the napped pile fabric is difficult to break, it is easy to obtain a napped pile fabric having a good appearance and a good hair removal property. When the adhesion amount of the adhesive resin is less than 30 g / m ² , the non-raised surface becomes hard and the wrinkle resistance is lowered, which is not preferable. On the other hand, even if the adhesion amount of the adhesive resin exceeds 300 g / m ² , an effect commensurate with the adhesion amount cannot be obtained in hardness and wrinkle resistance, which is not preferable in terms of cost.
The impregnation amount of the adhesive resin is more preferably 40 to 150 g / m ² from the viewpoint of productivity and cost.

  The glass transition point of the adhesive resin may be lower than room temperature, and more preferably −100 ° C. to 10 ° C. Moreover, it is more preferable that it is -50 degreeC-0 degreeC from the surface of productivity and cost.

  When a plurality of adhesive resins are used, the glass transition point of the adhesive resin can be suitably used in the present invention if the weight average value of each glass transition point is within the above temperature range.

  For example, 50 wt% adhesive resin A having a glass transition point of −50 ° C., 25 wt% adhesive resin B having a glass transition point of −110 ° C., and 25 wt% adhesive resin C having a glass transition point of 30 ° C. In the case of the adhesive resin, the glass transition point of the adhesive resin is −45 ° C. (the glass transition point of the adhesive resin = [glass transition point of the adhesive resin A × weight% of the adhesive resin A / 100] + [adhesion] Glass transition point of adhesive resin B × weight% of adhesive resin B / 100] + [glass transition point of adhesive resin C × weight% of adhesive resin C / 100]).

  The glass transition point of the adhesive resin can be measured by a thermomechanical analyzer (TMA) that measures changes in mechanical properties while slowly raising or lowering the sample temperature, Although it can be measured by differential scanning calorimetry (DSC) for measuring exotherm, it is not limited to these measuring methods.

  Below, the high pile fabric of this invention is demonstrated using drawing.

  FIG. 1 is a schematic diagram for explaining the positional relationship between a ground yarn and pile fibers entangled with the ground yarn in an embodiment of the high pile fabric of the present invention. As shown in FIG. 1, the high pile fabric 5 is spread on the ground yarn 1 constituting the knitted loop 6 and the raised surface 7 of the ground structure (high pile fabric 5) entangled with the loop 6 of the ground yarn 1 and the raised pile 3 It is comprised by the pile fiber 2 which forms. Further, at the non-raised surface 8 of the ground structure (high pile fabric 5), at least a part of the pile fiber 2 is thermocompression bonded outside the ground yarn 1 to form a thermocompression bonding portion 4, and is thermocompression bonded to the ground yarn 1. Yes. Note that FIG. 1 schematically shows a positional relationship in which pile fibers 2 are generally stacked on the lower side of the ground yarn 1, but in this figure, the outside of the ground yarn 1 is generally a diagram of the ground yarn 1. The lower part in 1 is meant.

  As described above, the high pile fabric of the present invention is suitable as a fabric for various uses such as clothing and rugs because the pile fiber is prevented from falling out and the texture and flexibility as a high pile are maintained. Can be used. Specifically, an imitation fur or a fake fur, a car seat, a carpet and the like can be exemplified, but are not limited thereto.

  In the present invention, the hot pressure treatment is performed at a temperature not lower than the softening point of the pile fiber and lower than the softening point of the fiber constituting the ground yarn from the non-raised surface of the raised pile fabric. Thereby, among the pile fibers entangled with the ground yarn, at least a part of the pile fibers outside the ground yarn is thermocompression bonded. The contact heating and pressurization can be performed by, for example, a heating roll or a hot plate. In the case of using a heating roll or a hot plate, a short-time contact heating and pressing treatment can be performed, and at least a part of the pile fibers outside the ground yarn can be thermocompression bonded on the non-raised surface of the ground texture. And since it does not heat to the extent that the pile fiber of the raised surface of the high pile fabric melts, the pile fiber raised on the raised surface of the ground tissue does not melt.

  When the heat pressure treatment is performed from the non-raised surface side of the ground structure and / or after the hot pressure treatment, the pile fiber side raised on the raised surface of the high pile fabric is preferably cooled. Moreover, it is preferable to cool from the non-raised surface side of the ground tissue after contact heating and pressurization from the non-raised surface side of the ground tissue. As the cooling means, it is preferable to cool the raised surface of the high pile fabric with a cooling roll in which water having a water temperature of 30 ° C. or less is passed. With such cooling, dimensional stability can be maintained and thermal damage to the pile fibers can be reduced.

  An example of an embodiment of the manufacturing method of the first example will be described in more detail with reference to the drawings.

FIG. 2 is a production process diagram schematically showing a process of contact heating and pressing at a predetermined temperature from the non-raised surface side of the knitted high pile fabric. The processing apparatus 30 used in this method includes a heating roll 31 coated with a fluororesin such as polytetrafluoroethylene, a cooling rubber roll 32 that pressurizes the heating roll 31 and allows 30 ° C. cooling water to flow inside, Metal cooling rolls 33 and 34 that pressurize the rubber roll 32 and allow 30 ° C. cooling water to flow therein, and a guide roll 35 are included. The high pile fabric original 38 is led out from the container 36 and supplied so that the non-raised surface 38 b comes into contact with the heating roll and the raised surface (the raised pile side) 38 a comes into contact with the cooling rubber roll 32. The processed high pile fabric 39 is stored in the container 37. Note that the contact heating and pressurizing treatment is not limited to the processing apparatus shown in FIG. 2, and is performed by using an apparatus, a hot plate, and other apparatuses in which a part of the configuration of the processing apparatus shown in FIG. 2 is changed. Also good. In the contact heating and pressure treatment, the heating temperature may be, for example, not less than the softening point of the pile fiber and less than the softening point of the fiber constituting the ground yarn, and the applied pressure may be 0.01 to 100 kgf / cm ² (0.98 KPa to 9.8 in linear pressure). MPa), the feed rate of the original fabric is preferably 0.1 to 20 m / min, and the heater contact time is preferably 1 to 60 seconds. Further, from the viewpoint of reducing damage on the surface of the pile fabric, it is more preferable that the applied pressure is a linear pressure of 2.0 to 50 Kgf / cm ² (0.20 to 4.9 MPa) and the heater contact time is 1 to 10 seconds.

  In the present invention, since the napped pile fabric contracts in the wale direction during the hot-pressure treatment, the hot-press treatment may be followed by a stretching treatment in the wale direction.

  As a method and conditions for the stretching treatment, gripping both end portions (cloth ear portions) of the high pile fabric in the wale direction, the stretching ratio of the length in the wale direction (= [(length in the wale direction after stretching) − (stretching) Previous length in the wale direction)] / (length in the wale direction before stretching) × 100) is preferably pulled in the wale direction, more preferably about 7 to 15%, even more preferably Is about 8-12%.

  Moreover, when heating at the time of an extending | stretching process, it is preferable to process at 90-150 degreeC, 100-130 degreeC is more preferable, 105 degreeC-120 degreeC is further more preferable.

  Such stretching treatment can be performed using a known device such as a tenter. In general, the tenter is used to heat and set the fabric to a predetermined width while holding both the fabric ears while heating at a predetermined temperature. Thus, it may or may not be heated. Further, in the tenter, there are a clip type and a pin type as a method for holding the cloth ear part of the fabric, and either may be adopted, but a pin type is adopted from the viewpoint of process stability and / or productivity. Is preferred.

  When the stretching treatment is performed while heating the high pile fabric, it is preferably performed at a minimum low temperature and a low air volume so as not to damage the surface of the high pile fabric.

  EXAMPLES Hereinafter, the present invention will be described more specifically with reference to examples. However, the present invention is not limited to the following examples.

<Measurement method and evaluation criteria>
(Experimental example 1) Measurement of hair loss The surface of the high pile fabric is made of rubber brush (trade name "Prescale mat" 5mm (grain diameter), length 4cm, width 10.5cm, manufactured by Fuji Film) 600g While applying a constant load (14.3kg / cm ² ), stroke width 20cm, rubbing 10 times in the forward direction of the bristles, 10 times in the reverse direction, recovering hair loss with adhesive tape, and converting the weight to 1m ² The amount of hair loss was determined.

(Experimental example 2) Hair loss evaluation Based on the amount of hair loss, the hair loss was evaluated in four ranks as follows.
A: 0.3 g / m ² or less (very good level)
B: More than 0.3 g / m ² and 0.6 g / m ² or less (good level)
C: Over 0.6 g / m ² and 1.0 g / m ² or less (slightly defective level)
D: exceeding 1.0 g / m ² (defect level)

(Experimental example 3) Measurement of hardness of non-raised surface of high pile fabric Using a measuring device in which a weight of 200 g was further added to the body of a hardness measuring device (based on Teclock, GS-754G, ASTM D 2240), a high pile fabric was used. Five non-raised surfaces (150 mm × 150 mm) were measured, and the arithmetic average value was taken as the measured value of the hardness of the non-raised surface of the high pile fabric. The higher the value, the harder the non-raised surface of the high pile tends to become harder.

  Furthermore, there is a correlation between the hardness of the non-raised surface of the high pile fabric and the tendency to wrinkle of the non-raised surface of the high pile fabric, and the softer the non-raised surface is, the less likely it is to wrinkle.

(Experimental example 4) Evaluation of wrinkle resistance (hardness) of non-raised surface of high pile fabric The hardness of the non-raised surface of the high pile fabric was evaluated in four ranks as follows.
A: The measured value of the hardness of the non-raised surface of the high pile fabric is 25 or less, which is the same as the hardness of the non-raised surface of a general high pile fabric, and no wrinkle is generated. It can be used without any problems even in clothing applications that require drape.
B: Hardness measured value of non-raised surface of high pile fabric is more than 25 and 30 or less. It is slightly harder than the hardness of non-raised surface of general high pile fabric, but wrinkle is hardly generated. It can be used without any problem even in clothing applications that require drape.
C: The measured value of the hardness of the non-raised surface of the high pile fabric is more than 30 and 40 or less. The hardness of the non-raised surface of the general high pile fabric is harder and more likely to be wrinkled. Difficult to use for clothing that requires drape.
D: The measured value of the non-raised surface of the high pile fabric exceeds 40 The hardness of the non-raised surface of a general high pile fabric is much harder and wrinkled. Cannot be used for clothing applications that require drape.

(Experimental example 5) Appearance and texture evaluation The appearance and texture of a high pile fabric raised surface were evaluated in the following four ranks.
A: Pile fibers raised on the surface of the ground structure are not fused, and are equivalent to a pile fabric that is not heat-treated. B: Although slightly inferior to rank A, the pile fibers raised on the surface of the ground structure are not fused. No, practically no problem Level C: Slightly rough, practically problematic (failed)
