Description

  The present invention relates to a mixed Angora fabric for clothing.

  There are various types of clothing fabrics, and among these, those woven using warp and weft yarns are widely used.

  For example, denim is a widely used fabric such as clothing and daily necessities. It is a cotton woven fabric made of twill using warp yarn dyed by indigo and weft yarn not dyed. It has a light and refreshing feel and durability, and a unique texture that is obtained through repeated use. It is used for various items such as outerwear and pants.

  By the way, a fabric made of warp and weft is generally easy to pass air from the weave of warp and weft. Therefore, when a user wears a garment made using such fabrics in a windy environment in winter, external cold air can enter the garment and the warm air inside the garment can be easily dissipated to the outside. There is a problem that it is not possible to ensure a cold protection.

  Conventionally, in order to improve the cold resistance of the fabric, to improve the cold resistance by using a fabric with a fleece lining (see Patent Document 1) or using wool on the weft yarn (see Patent Document 2) Has been done.

Utility model registration No. 3168774 Japanese Patent Laid-Open No. 10-130923

  However, fabrics with a fleece on the back of the outer material add to the thickness of the fleece, which may impair the comfort and appearance of clothes.

  In addition, when wool is used for the weft of the fabric, since wool is inferior to cotton, it may cause irritation when touched directly on the user's skin, resulting in itching and discomfort.

  Therefore, the present invention has been devised in view of the above-mentioned problems, and an Angola hybrid that can improve cold protection while realizing suppression of increase in fabric thickness and good comfort and touch. The purpose is to provide dough.

  The Angora hybrid fabric according to the first invention is spun using warp yarn spun using one or more of cotton, rayon or polyester, and one or more of cotton, rayon, polyester or polyurethane and angora hair. The angora hairs are mixed in a ratio of 1% or more and 8% or less.

  The Angora hybrid fabric according to the second aspect of the present invention is the first aspect of the invention, in which the weft yarn spun using one or more of cotton, rayon and polyester, and one or more of cotton, rayon, polyester and polyurethane and angora hair And warp yarns spun using the angora hair, and the mixed ratio of the Angora hair is 1% or more and 8% or less.

  The Angola hybrid fabric according to the third invention is characterized in that, in the first invention or the second invention, the heat retention measured by the dry contact method is 27% or more.

The Angola hybrid fabric according to the fourth invention is characterized in that, in any one of the first invention to the third invention, the air permeability measured by the Frazier method is 3 cm ³ / cm ² · sec or less.

  The Angola hybrid fabric according to a fifth aspect of the present invention is characterized in that, in any one of the first to fourth aspects, the warp yarn is indigo-dyed denim.

  An Angora hybrid fabric according to a sixth aspect of the present invention is circularly knitted using a yarn for circular knitting spun using at least one of cotton, rayon, polyester, and polyurethane and Angora hair, and the mixing ratio of the Angora hair Is 1% or more and 8% or less.

  According to the present invention having the above-described configuration, it is possible to provide an Angola hybrid fabric that can improve the cold resistance while realizing suppression of an increase in the thickness of the fabric and good comfort and touch.

It is a mimetic diagram showing Angola hybrid denim as Angola hybrid cloth concerning an embodiment of the present invention. It is the photograph which compared the Angola hybrid denim which concerns on embodiment of this invention, and the conventional 100% cotton denim.

  Hereinafter, Angola hybrid denim is demonstrated as an Angola hybrid fabric which concerns on embodiment of this invention. FIG. 1 is a schematic view showing an Angola hybrid denim 1 as an Angola hybrid fabric according to an embodiment of the present invention.

  The Angola hybrid denim 1 according to the present embodiment uses warp yarn 2 spun using one or more of cotton, rayon, or polyester, and one or more of cotton, rayon, polyester, or polyurethane and angora hair. Weaved using weft yarn 3 spun.

  When the warp yarn 2 is spun using any two or more of cotton, rayon, and polyester, these may be formed by twisting each other, alternately with each other, or the first type of warp yarn 2 On the other hand, every second number of warp yarns 2 of the second type may be regularly arranged. Further, when the warp yarn 2 is spun using any two or more of cotton, rayon, and polyester, the warp yarn 2 may be irregularly arranged for the mixing method.

  The weft yarn 3 is in a state in which angora hairs 31 protrude from a weft yarn body 32 formed by twisting one or more of cotton, rayon, polyester and polyurethane and angora hair. In this weft 3, when spinning using any two or more of cotton, rayon, polyester and polyurethane, these may be formed by twisting each other, alternately with each other, or the first kind of weft The second type of weft yarn 3 may be regularly arranged with respect to the yarn 3 every several.

  Incidentally, the rayon used for the warp yarn 2 and the weft yarn 3 includes tencel and modal.

  The Angora hybrid denim 1 is given a softness by performing biowash after the fabric is woven using the warp yarn 2 and the weft yarn 3.

  During the biowash, a part of Angola hair is detached from the weft yarn 3, and a hollow portion is formed in the weft yarn 3. The air layer formed by the hollow portion and the air layer formed between the raised hairs 31 on the surface of the weft yarn 3 exhibit a heat insulating effect and exhibit the effect of increasing the heat retention rate of the Angola hybrid denim 1 described later.

  In the state of the finished product after biowashing, the mixed ratio of Angola hair of Angola hybrid denim 1 is 1% or more and 8% or less. If the mixed rate of Angola hair is less than 1%, sufficient cold protection cannot be obtained, and if it exceeds 8%, it becomes difficult to weave the fabric.

  The Angola hybrid denim 1 according to the present embodiment suppresses an increase in the thickness of the fabric because the fabric is not pasted separately for providing cold protection, unlike the cold weather fabric in which the fleece is combined with the conventional lining. It is possible to prevent impairing the comfort and appearance of clothes.

  In the Angola hybrid denim 1 according to the present embodiment, Angola hair is used, but this Angora hair is a material with less irritation when touching the skin than wool. Therefore, the Angola hybrid denim 1 has a good comfort and feel compared to a wool hybrid fabric such as a conventional wool hybrid denim.

  Moreover, the Angola hybrid denim 1 which concerns on this embodiment becomes 27% or more of the heat retention measured by the dry contact method.

  When the heat retention rate is 27% or more, the Angola hybrid denim 1 according to the present embodiment can store warmth due to body temperature, and has excellent cold resistance.

Furthermore, the Angora hybrid denim 1 according to the present embodiment has a gas permeability of 3 cm ³ / cm ² · sec or less measured by the Frazier type method.

Since the air permeability is 3 cm ³ / cm ² · sec or less, the Angola hybrid denim 1 according to this embodiment can prevent cold outdoor air from passing through the fabric in winter and has excellent cold resistance. It becomes.

  FIG. 2 is a photograph comparing Angola hybrid denim 1 according to an embodiment of the present invention with conventional 100% cotton denim.

  As shown in FIG. 2, the Angora hybrid denim 1 according to the present embodiment has a larger amount of raised hair than the conventional 100% cotton denim, and the gap between the warp yarn 2 and the weft yarn 3 is narrow.

  The Angola hybrid denim 1 according to the present embodiment having such a form has a high cold resistance as compared with a conventional 100% cotton denim. Hereinafter, the cold resistance of the Angola hybrid denim 1 according to the example will be described with experimental results.

  The Angola hybrid denim 1 according to the example and the conventional 100% cotton denim to be compared were those shown in FIG. This Angola hybrid denim 1 has an Angola hair mixture ratio of 2.4% and a thickness of 7.84 mm. The conventional 100% cotton denim has a thickness of 5.74 mm.

  First, a heat retention test was performed on the Angola hybrid denim 1 according to the example and a conventional denim made of 100% cotton by a dry contact method, and the heat retention rate was measured.

  The heat retention test was performed using a precision rapid thermophysical property measuring device KES-F7 (hereinafter simply referred to as a measuring device) manufactured by Kato Tech Co., Ltd.

  The laboratory where the measurement was performed was set to an environment of 20 ° C. and a humidity of 65%.

  The measuring device is provided with a hot plate of 100 mm x 100 mm. The dough serving as the test object is placed on the hot plate heated to 30 ° C, and the heat is retained by calculating the amount of heat dissipated through the dough. A sex test was conducted.

Specifically, the dough is placed on a hot plate maintained at 30 ° C., heated for 10 minutes while blowing air at 0.3 m / second, and the power consumption (W) without the dough is a, the dough The heat retention rate was calculated by the following equation, where b is the power consumption (W) in a state where is placed.
Thermal insulation rate (%) = (ab) / a * 100

  As a result of the heat retention test, the heat retention rate of denim made of 100% cotton was 23.0%, while the heat retention rate of Angola hybrid denim 1 according to this embodiment was 27.5%.

  From this, it turned out that the Angola hybrid denim 1 which concerns on a present Example is a fabric excellent in heat insulation and superior in cold prevention compared with the conventional 100% cotton denim.

Next, the air permeability test by the fragile type method was performed on the Angola hybrid denim 1 according to the embodiment and the conventional 100% cotton denim.

  In the air permeability test by the Frazier type method, first, five 200 mm × 200 mm test pieces were prepared and attached to the Frazier type tester, and the suction fan and the air hole were adjusted so that the inclined barometer had a pressure of 125 Pa, The pressure indicated by the vertical barometer at that time is measured.

The air permeability (cm ³ / cm ² · sec) is obtained from the measured pressure and the type of air hole used by the conversion table attached to the testing machine, so that air permeability can be obtained. Desired.

As a result of the air permeability test, the air permeability of the conventional 100% cotton denim is 489.0 cm ³ / cm ² · sec, while the air permeability of the Angola hybrid denim 1 according to this embodiment is 2.72 cm. As a result, the air permeability was significantly less than ³ / cm ² · sec.

  Thereby, it turned out that the Angola hybrid denim 1 which concerns on a present Example is a cloth | dough which was hard to let open air from the denim of the conventional 100% cotton, and was excellent in cold prevention.

  In the above-described embodiments and examples, the Angola hybrid denim 1 has been described as an example of the Angola hybrid fabric. However, the present invention is not limited to this, and other types of fabrics other than denim may be used.

  Even in the case of other types of fabrics other than denim, weaving using warp yarn spun using cotton and weft yarn spun using cotton and angora hair, and processes such as dyeing and washing It is necessary that the mixed ratio of Angola hair in the finished product is 1% or more and 8% or less.

  With such a fabric, it is possible to improve the cold resistance while realizing suppression of an increase in the thickness of the fabric and good comfort and feel like the Angola hybrid denim 1 described above.

  Furthermore, if it is an Angola hybrid fabric whose heat retention measured by the dry contact method is 27% or more, the cold protection can be further improved as in the above-described embodiment.

Moreover, if the air permeability measured by the Frazier type method is 3 cm ³ / s or less, the cold resistance can be further improved as in the above-described embodiment.

  In the embodiment described above, the case where angora hair is used for the weft yarn 3 has been described as an example. However, the present invention is not limited to this, and the angora hair may be used for the warp yarn 2. Good. In such a case, the configurations of the warp yarn 2 and the weft yarn 3 are interchanged, and the weft yarn 3 spun using one or more of cotton, rayon, or polyester, and any one of cotton, rayon, polyester, or polyurethane. It will be woven using the warp yarn 2 spun using one or more and Angora hair. In this embodiment, all the configurations are the same as those described above except that the configurations of the warp yarn 2 and the weft yarn 3 are interchanged.

  The present invention is the same when the Angora hybrid fabric 1 is formed by circular knitting. In such a case, it is configured by circular knitting with circular knitting yarn spun using one or more of cotton, rayon, polyester, and polyurethane and angora hair.

  Hereinafter, the Example of the Angola hybrid fabric 1 to which this invention is applied is described. About the Angola hybrid fabric 1, the warp yarn 2 is spun using cotton, and the weft yarn 3 is spun using cotton and Angora hair. At this time, the heat retention superiority, the production stability, and the cost superiority with respect to the mixed use rate of Angola hair in the weft yarn 3 were experimentally verified. Table 1 shows the verification results of the heat retention superiority, manufacturing stability, and cost superiority for each sample. Each sample was made and experimented in the range where the mixed rate of Angola hair was 0.5% to 8%.

  The measurement method of the heat retention superiority was evaluated based on the heat retention test described above. In this heat retention test, each heat retention rate was measured, and graded in 18 stages according to the size. The higher the heat retention rate, the higher the numerical value of the grade.

  The production stability was evaluated based on a questionnaire survey conducted on three persons (both in their 40s and men) actually created at the factory. The production stability was graded in five stages based on the evaluation results. The higher the manufacturing stability, the higher the numerical value of the grade.

  For cost advantage, the total amount of material costs was obtained. About this cost advantage, it graded into five steps based on the total amount of material cost. The lower the total amount of material, the higher the value.

  As shown in Table 1, in Comparative Example 1, the mixed ratio of Angola hair was less than 1%, so the heat retention grade was 1. Since grade 1 is not much different from the heat retention of conventional denim, it cannot be said that the effects of the present invention can be obtained.

  In Comparative Example 2, since the mixed use ratio of Angola hair exceeded 8%, the production stability was extremely lowered, and the cost advantage was at the lowest level. The production stability grade of 1 is a level at which it is difficult to spin and finish in a desired shape.

  In Examples 1 to 15 of the present invention, since the mixed rate of Angola hair is included in the range specified in the present invention, the heat retention grade is 2 or more, and the production stability and cost advantage are excellent. It was a thing.

  Among them, Examples 2 to 5 of the present invention have excellent heat retention superiority, manufacturing stability, and cost superiority in grades of 3 or more, and are excellent in each characteristic. Furthermore, Examples 3 and 4 of the present invention all have excellent heat retention superiority, manufacturing stability, and cost superiority with grades of 3 or more, and are excellent in each characteristic.

  In the examples in Table 2 (Invention Example 16 to Invention Example 29), any one of cotton, rayon and polyester is used as the warp yarn, and Angola hair is essential as the weft yarn, and cotton and rayon are used. Any one or more of polyester, polyurethane is used. The numerical values in the table indicate the mixed rate for each warp and weft yarn. There are three evaluation items: heat retention advantage, manufacturing stability, and cost advantage.

  In these Invention Example 16 to Invention Example 29, the mixed ratio of Angola hair is 1% or more and 8% or less, and is in the range of 1.5 to 3.5% that exhibits particularly excellent characteristics. Has been.

  As shown in Table 2, the inventive examples 16 to 29 show excellent characteristics with respect to heat retention superiority, production stability, and cost superiority. For this reason, by setting the mixed rate of Angola hair within the range defined in the present invention described above, even if the warp yarn and the weft yarn are made of a material other than cotton, the desired effect can be exhibited. Was confirmed.

  In the examples in Table 3 (Invention Example 30 to Invention Example 43), Angola hair is essential as a circular knitting yarn, and one or more of cotton, rayon, polyester, and polyurethane are used. The numerical values in the table indicate the mixing ratio of the circular knitting yarn. There are three evaluation items: heat retention advantage, manufacturing stability, and cost advantage.

  In these Invention Example 30 to Invention Example 43, the mixing ratio of Angola hair is 1% or more and 8% or less, and is in the range of 1.5 to 3.5% that exhibits particularly excellent characteristics. Has been.

  As shown in the results of Table 3, Invention Examples 16 to 29 of the invention all showed excellent characteristics with respect to heat retention superiority, production stability, and cost superiority. For this reason, it was confirmed that the desired effect was exhibited even when the mixed fabric was produced by circular knitting by setting the mixing rate of Angola hair within the range defined in the present invention described above. .
