Description

  The present invention relates to a method for producing a textile product including animal hair having a unique texture.

  As one of the methods for obtaining a soft and well-textured fiber product, it has been proposed that water-insoluble spun yarn and water-soluble spun yarn are intertwisted, and the water-soluble spun yarn is dissolved and removed after weaving or knitting. (For example, refer to Patent Document 1).

JP 2008-190063 A

  The fiber product obtained by the method proposed in Patent Document 1 described above has a soft and soft texture as compared with the case where the water-soluble spun yarn is not used because the water-soluble spun yarn portion is dissolved and removed. Become. However, since the hardness of the water-insoluble spun yarn is the same as that without using the water-soluble spun yarn, a certain hardness can be felt.

  Accordingly, an object of the present invention is to provide a textile product having a softer texture while having elasticity and lightness.

  In order to solve the above problems, the present invention comprises a first step of mixing cashmere goat hair fiber and water-soluble vinylon fiber, and a mixture of cashmere goat hair fiber and water-soluble vinylon fiber. A second step of untangling the entangled fibers to obtain a collection of sheet-like fibers having a certain thickness and width, and the sheet-like fibers obtained in the second step are passed between fine countless needles. A third step of obtaining a thick rope-like sliver by stretching the opened sheet-like fibers straight and aligning them in parallel, and a single sliver while stretching a plurality of the sliver The 4th process to make, and the one sliver obtained by the said 4th process is further extended while adding twist, and the roving which is a fine string-like thing is obtained. And a sixth step of making a yarn of an appropriate thickness and number of twists by further stretching the roving obtained in the fifth step while adding twist, and using this yarn as a blended yarn, A seventh step of knitting a fiber product using the blended yarn obtained in the sixth step, and a treatment of the fiber product obtained in the seventh step with water at a temperature of 40 degrees Celsius or higher. And an eighth step of dissolving and removing the water-soluble vinylon fibers in the fiber product.

  The blended yarn obtained in the production process of the fiber product in the production method of the present invention has elasticity and lightness and becomes soft and soft when the water-soluble fiber is dissolved and removed. If a woven fabric or a knitted fabric is produced using such a yarn, a fiber product having a unique texture can be obtained. Moreover, after manufacturing a woven fabric or a knitted fabric using the blended yarn, a fiber product having a unique texture can be obtained by dissolving and removing the water-soluble fibers contained in the woven fabric or the knitted fabric.

FIG. 1 is an image diagram for explaining a difference between a fiber product manufactured using a twisted yarn according to the prior art and a fiber product manufactured using a blended yarn according to the present invention.

(Embodiment)
Hereinafter, a blended yarn which is an embodiment of the present invention and a production method for producing a fiber product using the blended yarn will be described.

  The blended yarn according to the present embodiment is composed of cashmere goat wool fibers and water-soluble fibers having a water dissolution temperature of 30 degrees Celsius or more and 50 degrees Celsius or less (more specifically, a water soluble fiber having a water dissolution temperature of 40 degrees Celsius). And vinylon fiber). Moreover, in the manufacturing method according to the present embodiment, a sweater that is a textile product is knitted using the blended yarn obtained as described above, and then contained in the sweater with hot water of 40 degrees Celsius or more. The water-soluble vinylon fiber is dissolved and removed to produce a sweater as a final product.

  Cashmere goat hair fibers and water-soluble vinylon fibers are mixed in a weight ratio of 7: 3, for example. What is necessary is just to select the ratio of this mixing suitably according to the elasticity, lightness, etc. of the textiles to obtain finally.

  The spinning method that can be adopted in the practice of the present invention may be any existing spinning method using animal hair fibers. Hereinafter, an example of these methods will be briefly described. After mixing the cashmere goat hair fiber and the water-soluble vinylon fiber, the foreign material such as dust in the raw material is removed while untangling the fibers, and the sheet-like fiber having a certain thickness and width is removed. Make a wrap. This process is performed by, for example, a blended cotton machine.

  Next, while the sheet-like fibers are opened by passing through a myriad of fine needles, unnecessary materials that have not been removed in the previous step are removed. Then, the fibers are stretched straight and aligned in parallel to make a thick rope (sliver). This step is performed by, for example, a carding machine.

  Next, a plurality of slivers are stretched together to form one sliver. At this time, the directions of the fibers are further aligned. This step is performed, for example, with a drawing machine.

  Next, the sliver is further stretched while twisting to make a thin string (coarse yarn). This step is performed by, for example, a roving machine. Then, the roving is further stretched while twisting to produce a yarn having an appropriate thickness and number of twists. This step is performed by, for example, a ring spinning machine.

  A blended yarn is thus produced. In this specification, the yarn before dissolving and removing the water-soluble fiber is referred to as “blended yarn”, and the yarn after dissolving and removing the water-soluble fiber is referred to as “spun yarn” in order to distinguish it. To do.

  In this embodiment, 100% cashmere goat hair fiber is used as the water-insoluble fiber. However, depending on the purpose, the cashmere goat hair fiber may be selected from other types of water-insoluble fiber. Water-insoluble fibers obtained by mixing at a weight ratio of may be used, or other animal hair fibers such as alpaca hair and wool may be used instead of cashmere goat's hair. Examples of water-insoluble fibers to be mixed with animal hair fibers include natural fibers such as cotton, hemp, and silk, and synthetic fibers such as polyester, polyamide, and polyacrylonitrile.

  Similarly, in the present embodiment, a water-soluble vinylon fiber having a water dissolution temperature of 40 degrees Celsius is employed as the water-soluble fiber, but it does not dissolve at room temperature and does not damage animal hair fibers. Therefore, any water-soluble vinylon fiber having a water dissolution temperature of 30 degrees Celsius or more and 50 degrees Celsius or less may be used. Moreover, you may employ | adopt water-soluble fibers other than water-soluble vinylon fiber which satisfy | fill the same water dissolution temperature conditions.

  Next, a sweater is knitted using the obtained blended yarn. In general, a sweater is one of textile products in which the texture is emphasized in addition to elasticity and lightness, and since the effects of the present invention often appear, it is selected as a specific example of the textile product in this embodiment. Therefore, any fiber product other than a sweater may be manufactured by the method according to the present invention, as long as the fiber product emphasizes elasticity, lightness and texture. Further, the textile product is not limited to knitting but may be produced by weaving. Furthermore, even if the above-mentioned blended yarn is not used as a whole, a certain effect can be obtained for the above-mentioned purpose as long as it is used at least in part.

  The knitted sweater is treated with water having a temperature of 40 degrees Celsius or higher (for example, hot water of 60 degrees Celsius), so that the water-soluble vinylon fibers in the sweater are dissolved and removed. As a result, the above-mentioned object is achieved, and as a result, a textured sweater having a unique feeling of air is obtained. Here, the temperature of the hot water may be a temperature other than 60 degrees Celsius, but if the dissolution and removal treatment is performed at a relatively high temperature for a long time, the fiber of the animal hair will be greatly damaged, If the dissolution and removal treatment is performed for a short time at a relatively low temperature, a part of the water-soluble fiber remains in the product.

  In addition to the method of obtaining the fiber product by dissolving and removing the water-soluble fiber after knitting the blended yarn, etc., the method of producing the fiber product by knitting the spun yarn from which the water-soluble fiber has been dissolved and removed first. May be adopted.

The above is the details of the present embodiment. According to this embodiment, the following effects can be obtained.
First, if the blended yarn obtained in the production process of the fiber product in the production method of the present embodiment is made by dissolving and removing water-soluble fibers (spun yarn), it has elasticity and lightness and is soft. It becomes a thread with a natural texture. If a woven fabric or a knitted fabric is produced using the spun yarn, a fiber product having a unique texture can be obtained. Moreover, after manufacturing a woven fabric or a knitted fabric using the blended yarn, a fiber product having a unique texture can be obtained by dissolving and removing the water-soluble fibers contained in the woven fabric or the knitted fabric.

  Secondly, since the blended yarn obtained in the production process of the textile product in the production method of the present embodiment uses cashmere goat hair as animal hair, it can be used for producing a textile product that is soft and has good heat retention. It is.

  Thirdly, the blended yarn obtained in the production process of the fiber product in the production method of the present embodiment employs a water-soluble fiber having a water dissolution temperature of 30 degrees Celsius or more and 50 degrees Celsius or less. The water-soluble fiber can be dissolved and removed without minimizing damage to the fiber itself even when high-grade animal hair that is weak at high temperature is used without dissolving the water-soluble fiber at room temperature.

  Fourthly, according to the manufacturing method of the present embodiment, since weaving or knitting is performed using the blended yarn with the strength of the water-soluble fiber, the process management is not accompanied by much difficulty, and thereafter By dissolving and removing the water-soluble fiber, it is possible to easily produce a fiber product having elasticity and lightness and having a unique texture.

(Modification)
The above-described embodiments can be variously modified within the scope of the technical idea of the present invention. The modification is shown below.

  If an air cap making machine is used in the spinning process described above, the productivity of blended yarn can be increased. Specifically, a sliver made by the above-mentioned drawing machine is supplied to an air cap machine, and the blended yarn is spun from the air cap machine.

  The blended yarn produced in this way is composed of a central portion that is a group of fibers with almost no twist, and a bundling portion that is a group of fibers wound around the central portion so as to bundle the central portion.

  In this case, the above-mentioned central portion is mainly composed of cashmere goat hair fibers (containing cashmere goat hair fibers of more than 0.5 by weight), and the binding portion is mainly composed of water-soluble vinylon fibers (water-soluble). If the composition is made of a vinylon fiber containing more than 0.5 by weight), the water-soluble vinylon fiber is dissolved and removed, so that the amount of the fiber group mainly constituting the binding portion is reduced and the binding state As a result, it is possible to obtain a textile product that is soft, has a good texture, and is light.

  In order to make the central part mainly composed of cashmere goat hair fibers and the binding part mainly composed of water-soluble vinylon fibers, the latter fiber length is about 30% longer than the former fiber length. Although it is desirable to employ a method of blending, it is not limited to this.

  In addition, when mixing cashmere goat hair fiber and water-soluble vinylon fiber, by adjusting the weight ratio and fiber length of both, a fiber product having elasticity and lightness according to the purpose can be obtained. .

  Fig. 1 (a) is a diagram showing an image of a fiber product manufactured using the twisted yarn 1 shown in Patent Document 1, and Fig. 1 (b) shows a blended yarn 2 according to the present invention. It is a figure showing the image of the textiles manufactured using.

  As shown in the figure, when water-soluble fibers are dissolved and removed from a textile product woven and knitted using the twisted yarn 1 of Patent Document 1, a portion of the water-soluble spun yarn represented by white circles melts away. Only the water-insoluble spun yarn portion represented by the black circle remains.

  On the other hand, when the water-soluble fiber is dissolved and removed from the blended yarn 2 according to the present invention (or the fiber product woven / knitted using the same), the number of yarns constituting the fiber product is not changed, A portion of the water-soluble fiber melts from each yarn itself, and each yarn has a sponge property. As a result, a textile product with a unique and airy feeling is produced.

According to the method for producing a blended yarn or fiber product of the present invention, it is possible not only to have elasticity and lightness, but also to produce a fiber product having a soft feeling and a unique air feeling.
From the above, the blended yarn or fiber product production method of the present invention can be applied to the production of various fiber products, and can be used for the production of hats, underwear, gloves, socks and the like. I can expect.
