Description

  TECHNICAL FIELD The present invention relates to a fabric for clothing that fits the body when wearing innerwear, sportswear, etc., and is configured to have the highest heat retention when worn as clothing.

  Conventionally, many studies have been conducted in order to obtain wearing comfort of clothing. Especially for clothing used in winter, it is required to increase the heat retention effect. In addition to examining the thickness of the fabric and the woven / knitted structure, various warmth effects such as the adoption of hollow fibers are appropriate. Have gained. However, these mainly use the heat insulating effect and can suppress the heat dissipation of the human body, but it may be difficult to maintain sufficient heat retaining performance in a low temperature environment. In addition, some heat-absorbing heat-generating materials have been used to obtain a warming effect, but since heat-generating heat-retaining properties associated with sweating are used, the effect is weak when sweating does not occur and the sustainability is insufficient. It was.

  On the other hand, in order to improve the heat retention by using sunlight or infrared rays emitted from the human body, iron oxide as a heat storage heat insulating material is kneaded into the fiber (Patent Document 1), or an infrared absorbent is adhered to the fabric surface. (Patent Document 2) technology has been proposed. However, these clothing products are effective against strong infrared rays such as sunlight outdoors, but there is a problem that the heat retention performance is reduced in an environment where strong infrared rays such as an indoor environment do not hit.

  In addition, a technique has been proposed in which a film on which a metal having a high heat ray reflection effect is deposited is laminated on a cloth to obtain heat retention (Patent Document 3). However, in this technique, since the vapor deposition film is laminated, the texture is hard, there is no air permeability, and the wearing comfort is very low.

  Furthermore, a method of directly depositing a metal having a high heat ray reflection effect on a fabric or a nonwoven fabric has been proposed (Patent Document 4). However, when used for clothing, deterioration of the metal surface due to repeated wearing and washing becomes a problem. There were many cases.

  In the above-described conventional technology, the heat retention of unstretched clothing is studied. On the other hand, innerwear or the like is worn in an extended state in order to fit the body. Up to now, there has been no attempt to examine the elongation rate and the heat retention rate at the time of wearing the clothing worn in the stretched state.

  Therefore, in the present invention, ascertaining the relationship between the stretch rate and the heat retention rate of clothing worn in the stretched state of innerwear, sportswear, etc., the issue is to provide a fabric excellent in heat retention in the worn state It was.

  As a result of intensive studies to achieve the above-mentioned problems, the present inventors have completed the present invention.

  The present invention is a fabric for clothing worn in an elongated state, and in the fabric showing the maximum value when measuring the heat retention rate while stretching the fabric, the area elongation at the time of wearing the clothing obtained from the fabric When the rate is X% with respect to the unstretched fabric and the area stretch rate when the maximum heat retention rate of the fabric is Y% with respect to the unstretched fabric, X-20 ≦ It is applied to the cloth for clothing excellent in the heat retention at the time of wearing which has the characteristics in the place manufactured so that it may be set to Y <= X + 20.

  Here, the area elongation rate means the elongation ratio of the area ratio with respect to the unstretched fabric. For example, the fabric stretches 1.2 times in the warp direction and 1. When stretched twice, the area stretch rate is 144%. In the area elongation rate, “100%” is not stretched.

  It is preferable that at least one of the warp direction and the weft direction has an elongation rate of 30% or more and an elongation recovery rate of 70% or more with respect to the unstretched fabric. When stretched in either the warp direction or the weft direction, the stretch rate is 1% (not stretched) 0%. For example, when stretched 1.3 times in the warp direction, the stretch rate is 30%. . Further, the elongation recovery rate is defined as 100% when the stretched rate is completely returned to the original (unstretched) length after measurement. A detailed method for measuring the elongation rate and the elongation recovery rate will be described later. Note that the term “elongation rate” instead of “area elongation rate” refers to the elongation rate in one direction.

  X% is preferably 220% or less in terms of the area elongation ratio relative to the unstretched fabric.

Further, the air permeability of the fabric when not stretched is preferably ³⁰ to 350 cc / cm ² · sec, and the apparent specific gravity is preferably 0.10 to 0.40 g / m ³ .

  When the clothing fabric is a tricot knitted fabric, the cover factor is preferably 1600 to 3000, and when the clothing fabric is a Russell knitted fabric, the cover factor is preferably 4000 to 6000.

  The maximum value of the heat retention rate when the fabric is stretched is 1.2 times or more of the heat retention rate of the unstretched fabric, the washing dimensional change rate is −5% to + 2%, heat setting It is a preferred embodiment of the present invention that any of the above has been received two or more times.

  A clothing fabric suitable for a body suit having an area elongation rate of 110 to 140% with respect to an unstretched fabric when the fabric exhibits a maximum value of the heat retention rate, and the fabric exhibits a maximum value of the heat retention rate When the area elongation rate is 110-140% with respect to the unstretched fabric, the fabric for clothing suitable for the camisole, the area stretch rate when the fabric shows the maximum value of the heat retention rate is in the unstretched state The cloth for clothing suitable for sportswear which is 110 to 140% of the cloth, and the area elongation rate when the cloth shows the maximum value of the heat retention rate is 140 to 180% with respect to the unstretched cloth. Apparel fabric suitable for girdle, apparel fabric suitable for shorts whose area elongation rate is 160 to 200% of the unstretched fabric when the fabric exhibits the maximum heat retention rate, and book Use the clothing fabric of the invention Clothing produced Te are all encompassed by the present invention.

  Since the fabric of the present invention is configured to have the highest thermal insulation rate when worn, it is very useful as a thermal insulation material used for clothing that fits the body.

It is a graph of the area expansion rate and heat retention of the fabric obtained in Examples 1-3. It is a graph of the area expansion rate and heat retention of the fabric obtained in Examples 4 and 5. It is a graph of the area expansion rate and heat retention rate of the cloth obtained in Comparative Examples 1 and 2.

  The present invention will be specifically described below.

  The present inventors examined the relationship with the area elongation rate for the heat retention of stretchable fabrics. Increasing the area elongation rate of the stretch fabric, that is, as the fabric is stretched, the gap between the yarns in the stitches and weaves becomes larger, so the warmed air escapes and the heat retention rate decreases Has been considered. However, as a result of investigation by the present inventors, when a fabric having a predetermined property is stretched, the heat retention rate gradually increases, reaches a maximum at a certain area elongation rate, and thereafter decreases, that is, a maximum. It was found to show a value (FIGS. 1 and 2).

  This phenomenon is presumed to have occurred because the heat insulation and heat-insulating effect was enhanced because the warm air layer present in the gaps in the fabric (woven or knitted fabric) increased due to stretching. And after the heat retention rate increases and shows the maximum value (peak), the structure of the fabric (woven or knitted fabric) becomes loose and the gap between yarns becomes too large. It is thought that the heat retention rate decreases due to the generation and the influence of a non-warm airflow outside the fabric.

  Considering the above phenomenon, if the area elongation rate of the fabric when wearing clothing matches the area elongation rate when showing the maximum value of the heat retention rate, the heat retention effect of the fabric can be exhibited most effectively. It will be possible.

  Therefore, the present invention is premised on a cloth for clothing worn in a stretched state and having a maximum value when the heat retention rate is measured while stretching the cloth. And the area elongation rate at the time of wear of the clothing obtained from the said cloth is X% with respect to the cloth of an unstretched state, and the area elongation rate when showing the maximum value of the heat retention rate of the said cloth is an unstretched cloth When Y is%, the point of the present invention is that the dough is produced so that X-20 ≦ Y ≦ X + 20, and the present invention relates to the dough thus produced.

  The above formula means that if the area elongation rate Y% when the maximum value of the heat retention rate is 140%, for example, is 140%, the fabric is suitable for clothing to be worn at 120% to 160%. Even if Y% is smaller than X% by more than 20% or larger than X% by more than 20%, clothes will be worn away from the zone where the heat retention rate shows the maximum value. This is not preferable because heat insulation cannot be secured. The upper limit of Y% is actually about 220%. Further, even if the heat retention rate takes a maximum value in a region with a high area elongation rate, it is not reflected in the actual clothing, and the heat retention effect of the fabric cannot be utilized. A more preferable upper limit of Y% is 200%. The heat retention rate at the maximum value is preferably 1.3 times or more, more preferably 1.4 times or more that of the unstretched fabric. Sufficient heat retention can be secured during actual wearing.

  As will be described later, since the area elongation rate at the time of wearing differs depending on the type of clothing, it is necessary to manufacture the fabric so that the heat retention rate is maximized in the worn state. Specifically, fabrics are made under certain conditions, and the area elongation rate when the maximum heat retention rate is shown from the measurement of the area elongation rate and the heat retention rate, and the fabric density (course, wale) at that time are grasped. The fabric is designed so that the heat retention rate is in the vicinity of the maximum value in the worn state by calculating backward from the area elongation rate at the time of wearing. For example, if the area expansion rate indicating the maximum heat retention rate is smaller than the area expansion rate at the time of wearing, the fabric density may be increased, and the area expansion rate indicating the maximum heat retention rate is the area expansion rate at the time of wearing. If larger, the fabric design is performed so that the fabric density is lower. And if you change and adjust the production conditions of the raw machine (knitted fabric before scouring) and the conditions of the heat set (preliminary set, finishing set, etc.) in the processing process, and finish according to the fabric design above, the heat retention rate in the worn state Can produce a fabric having a value near the maximum value. At the same time, adjust the production conditions of the machine and the conditions of the heat set (preliminary set, finish set, etc.) so that the physical properties such as stretchability, stretch recovery, and dimensional change rate are within the range where there is no practical problem. There is a need.

  The fabric of the present invention preferably has an elongation rate of 30% or more and an elongation recovery rate of 70% or more in at least one of the warp direction and the transverse direction with respect to the unstretched fabric. For example, if stretched by a factor of 1.3 in the warp direction or the weft direction, a fabric having a stretchability of 30% is obtained. Moreover, if it returns 70% from the extended state, it will have a 70% recovery rate. When the elongation rate is low, the pressure applied during wearing may increase, and discomfort may occur.In addition, although there is an improvement in heat retention due to the elongation, the fabric does not reach the peak region of heat retention. There is a possibility of reaching the limit of extensibility, which is not preferable. On the other hand, if the elongation recovery rate is less than 70%, the fabric becomes “soft” when worn, which is not preferable in appearance, and the space with the skin due to the “soft” prevents the securing of a stable heat-retaining air layer. May be worse.

  The fabric of the present invention may be a woven fabric or a knitted fabric (knitted) such as circular knitting or warp knitting. In the case of a woven fabric, it is possible to make a fabric that is thin and lightweight and has excellent strength and wear. In the case of a knitted fabric, a fabric having both extensibility and soft texture can be produced. A knitted fabric is preferable in terms of easy control of heat retention and elongation and a high area elongation rate. The knitted fabric may be either circular knitting or warp knitting, but warp knitting is more preferable because warp knitting is easier to control by heat setting of the fabric and the value of the dimensional change rate is easier to control. In particular, a tricot knitted fabric or a raschel knitted fabric is preferable.

  Although it does not specifically limit as a raw material of the fabric used for this invention, It is preferable that the synthetic fiber is used from the point which is easy to control by the heat setting of a fabric, The mixture ratio of the synthetic fiber with respect to the whole fabric is 40 mass% or more. Preferably there is. A more preferable mixing ratio is 50% by mass or more, and further preferably 60% by mass or more. Synthetic fibers include polyester fibers such as polyethylene terephthalate, polytrimethylene terephthalate, polybutylene terephthalate; polyamide fibers such as nylon 6 and nylon 66; acrylic fibers; polyolefin fibers such as polypropylene and polyethylene; polyurethane fibers; It is done.

  Moreover, it is preferable that elastic fibers are contained in the material of the fabric (woven or knitted fabric) of the present invention. Due to the effect of this elastic fiber, it is possible to obtain the elongation rate, the area elongation rate and the elongation recovery rate necessary for the fabric. In addition, since the space in the dough becomes dense, it becomes easier to control the heat retention during stretching. Examples of elastic fiber materials include polyether-based urethane, polyester-based urethane, polytrimethylene terephthalate, polybutylene terephthalate, and cross-linked polyolefin fiber. In consideration of extensibility and setability, polyether-based urethane and polyester Polyurethane fibers such as polyurethane are desirable. These fibers can be formed into a shape such as a modified cross-section yarn, a composite cross-section yarn, or a crimped yarn, so as to obtain a higher elongation rate / area elongation rate or elongation recovery rate.

  The elastic fiber may be knitted directly (single) into the fabric (woven or knitted fabric), or the fabric may be made using a core yarn or covering yarn composed of these elastic fibers. In consideration of securing the above-described elongation rate / area elongation rate and elongation recovery rate and controlling the heat retention during elongation, the mixture ratio of elastic fibers in the entire fabric is preferably 5% by mass or more. However, if it exceeds 50% by mass, it is difficult to set the dough and the dimensional change rate may be deteriorated.

The dough of the present invention preferably has an air permeability of 30 to 350 cc / cm ² · sec when not stretched. If the air permeability is smaller than 30 cc / cm ² · sec, the space in the fabric becomes too dense, and there is a possibility that the heat retaining property during wearing will not be sufficiently high. A more preferable lower limit of the air permeability is 40 cc / cm ² · sec. On the other hand, if it exceeds 350 cc / cm ² · sec, there is too much space in the fabric, heat is likely to escape, and heat retention may be reduced. A more preferable upper limit of the air permeability is 300 cc / cm ² · sec.

The apparent specific gravity of the dough of the present invention is preferably 0.10 to 0.40 g / m ³ . If it is less than 0.10 g / m ³ , the space in the dough becomes too large, heat is likely to escape, and heat retention may be reduced. A more preferable lower limit of the apparent specific gravity is 0.13 g / m ³ . On the other hand, if the apparent specific gravity exceeds 0.40 g / m ³ , the space in the fabric becomes too dense, and there is a possibility that the heat retaining property during wearing will not be sufficiently high. A more preferable upper limit of the air permeability is 0.38 g / m ³ .

  Further, the cover factor of the fabric of the present invention is preferably 1600 to 3000 in the case of tricot knitted fabric, and preferably 4000 to 6000 in the case of Russell knitted fabric. If the cover factor is smaller than the lower limit of each suitable range, the space in the fabric becomes too much, heat is likely to escape, and there is a possibility that the heat retaining property is lowered. On the other hand, if the cover factor exceeds the upper limit of each suitable range, the space in the fabric becomes too dense, and there is a possibility that the heat retention at the time of wearing will not be sufficiently high. More preferable cover factor ranges are 1800 to 2800 for tricot knitted fabric and 4500 to 5500 for raschel knitted fabric.

  The tricot knitted fabric can be manufactured by a known method using a tricot knitting machine and the raschel knitted fabric can be manufactured using a raschel knitting machine. In the case of a woven fabric, it can be produced by a known method.

  After the production machine is manufactured, each process such as scouring, relaxing, preliminary setting, dyeing, finishing setting, sewing and the like may be selected as appropriate. In the production of the dough of the present invention, the heat setting process is performed twice or more, such as a preliminary setting and a finishing heat setting, so that the above-described elongation rate, area elongation rate, and elongation recovery rate can be set within preferable ranges. It is preferable. The space in the dough can be made as designed, and the dough can be manufactured with good stability. By performing the heat setting twice or more, the washing dimensional change rate can be suppressed to the range of -5% to 2%, and there is no problem in actual use.

  The fabric of the present invention is a clothing fabric worn in an expanded state. The clothing worn in the stretched state means that the cloth of the clothing in the worn state is stretched more than the unworn state, and the clothing configured to fit the body corresponds. In addition, even when a part of clothing is extended, it is included in the clothing worn in the extended state. Moreover, the cloth of the present invention can be used only for a part of the clothing. When the cloth is partially used in this way, the cloth of the present invention can be used only for the portion to be kept warm, which is efficient. As a method for producing a partial heat retaining region, it may be produced by a turn-back pattern at the time of sewing, or can be produced using a jacquard loom or the like. In addition, by using a printing machine or adopting an opal processing method, a portion having higher heat retention during wearing and other portions may be mixed in one fabric. It is also possible to make a fabric that is more excellent in wearing comfort by arranging the heat insulation region in a pattern or developing it in a gradient shape.

  The fabric of the present invention is a fabric for clothing worn in an elongated state. Examples of such clothing include girdle, body suit, camisole, shorts, brassiere, inner (shirt) that fits the body, etc. Innerwear for women; clothing for the lower body of tights, spats, leggings, high socks, socks, etc .; Innerwear for men such as boxer shorts, fit type briefs; sports bras, supporters, rash guards, under armor ("Under Armor is Registered trademark "), sportswear such as leotards and swimsuits.

  When the fabric of the present invention is applied to a body suit, it is preferable to manufacture the fabric so as to show the maximum value of the heat retention rate in the area where the area elongation rate is 110 to 140%. This is because the elongation rate when the body suit is worn is approximately 110 to 140%.

  In addition, it is preferable that the camisole and sportswear of the type to be fitted to the body be manufactured so that the area elongation rate is 110 to 140% and the maximum value of the heat retention rate is exhibited.

  In the case of a girdle, since the elongation rate at the time of wearing is larger, it is preferable to manufacture the fabric so that the maximum value of the heat retention rate is obtained when the area elongation rate is 140 to 180%. Since the area elongation rate when wearing shorts is even greater, it is preferable to fabricate the fabric so that the maximum value of the heat retention rate is obtained when the area elongation rate is 160 to 200%.

  The present invention also includes apparel manufactured using the fabric with controlled area elongation rate and heat retention rate as described above, that is, body suit, camisole, girdle, shorts, sportswear, and other apparel described above. It is. Each of these garments is manufactured by a known method.

  The present invention will be described more specifically with reference to the following examples.
