Description

  The present invention relates to a conductive molding yarn suitable for knitting such as a glove capable of touch panel operation, and a glove knitted entirely with the conductive molding yarn.

  In recent years, touch panel devices such as capacitive touch panel mobile phones have begun to spread. On the other hand, in winter, gloves are often worn on the hand, and there are cases where it is desired to operate the touch panel mobile phone while wearing the glove.

  While wearing gloves, holding a touch panel mobile phone with one hand and operating the touch panel with the fingertip of the other hand, the capacitive touch panel Because the general knitting yarns that make up gloves have physical properties similar to insulators, even if a predetermined part of the touch panel is pressed with a fingertip, current is not applied to the knitting yarn that forms the finger bag part. Capacitance is not detected. That is, since the capacitance of the touch part of the touch panel does not change with the gloves on, the touch panel cannot be operated as a result.

  As one of the gloves capable of operating a capacitive touch panel, as disclosed in Patent Document 1, only the tip portions of the thumb bag portion and the index finger bag portion are knitted with conductive fibers, and all the remaining The part of is knitted with general knitting yarn.

  As one of general-purpose conductive fibers, there are known fibers in which copper sulfide is chemically bonded to resin fibers such as acrylic fibers and nylon fibers to impart conductivity. Other general-purpose conductive fibers include those in which micron-sized carbon black is kneaded into resin fibers such as acrylic fibers and nylon fibers, and metal-plated fibers in which the surface of the fibers is electrolessly plated. However, these conductive fibers are hardened by the above-described conductivity imparting manufacturing method (processing). For this reason, there is no problem when knitting only the tip portion of the thumb bag portion and index finger bag portion with high frequency of touch panel operation with the conductive fiber, but when the entire glove is knitted with the conductive fiber, In addition to the problem of cost, the entire glove had a hard feeling and there was a problem that the feeling of wearing was bad.

Utility Model Registration No. 3160211

  An object of the present invention is to provide a conductive mould yarn suitable for knitting such as a glove capable of touch panel operation, and a glove that is knitted as a whole and has a soft wearing feeling.

  The invention of claim 1 for solving the above-mentioned problem is a molding yarn comprising a core yarn and a flower yarn, and a binder yarn for bonding the core yarn and the flower yarn, wherein at least one of the core yarn and the flower yarn. One side is a conductive molding yarn characterized by containing conductive fibers.

  Since the conductive molding yarn according to the invention of claim 1 has a structure in which at least one of the core yarn and the flower yarn contains conductive fibers, clothing-related products such as gloves and mufflers are knitted with the conductive molding yarn. In this case, compared to the case where the whole is knitted with conductive yarn, it has the softness, warmth, or fluffy feeling that is the original characteristic of the molding yarn, and also has conductivity. In addition, it is highly effective to organize clothing-related products that can be worn directly on the human body, such as gloves that can be operated on the touch panel while worn on the hand, mufflers that can prevent static electricity and static electricity, and socks.

  The device of claim 2 is characterized in that, in the device of claim 1, the conductive fiber is a composite of nano-sized metal particles inside.

  Conductive fibers in which nano-sized metal particles are combined have been developed at the time of this application. According to the invention of claim 2, the conductive fiber itself is compared with a fiber imparted with conductivity by chemically bonding copper sulfide, a metal-plated fiber imparted with electroless plating on the surface of the fiber, or the like. Since it is soft, there is an advantage that the inherent characteristics of the molding yarn are further exhibited.

  The invention of claim 3 is the invention of claim 2, wherein the core yarn is a 70 denier nylon yarn containing 20% of the conductive fibers, and the flower yarn is a 70 denier nylon containing 40% of the conductive fibers. A yarn and a 75 denier polyester yarn containing 40% of the conductive fiber are alternately sandwiched between the core yarn and the binder yarn.

  The conductive molding yarn according to claim 3 has conductivity, and is suitable for knitting gloves capable of touch panel operation based on the material and thickness of the core yarn and the flower yarn.

  Further, the invention of claim 4 is knitted as a whole with the conductive molding yarn according to any one of claims 1 to 3, and at least the thumb bag part and the index finger bag part are independent finger bag parts. A glove knitted with conductive molding yarn characterized by

  In addition to being able to operate by touching the tip of the thumb or forefinger to the touch panel, the gloves knitted entirely with conductive molding yarn have conductivity in all parts, Since the entire glove is knitted with conductive molding yarn containing conductive fibers in which nano-sized metal particles are combined with at least one of core yarn and flower yarn, copper sulfide is chemically bonded to resin fibers to conduct electricity. Unlike conductive fibers that are made by adding kneaded fibers, micron-sized carbon black, or conductive fibers that have been electrolessly plated on the surface of the fibers, they have the softness, warmth, or softness that is inherent to Mole yarn. Therefore, the wearing feeling is good.

  In addition to having conductivity, the conductive molding yarn according to the present invention has the softness and soft feel peculiar to molding yarn, so it is suitable for knitting gloves that allow touch panel operation. It can also be applied to clothing-related products that are directly attached to the human body, such as mufflers and socks capable of preventing electrostatic charge. In addition, since the conductive molding yarn according to the present invention includes conductive fibers in at least one of the core yarn and the flower yarn, the usage ratio of the conductive fibers can be reduced. Compared to knitting, the knitted product can be knitted at a low cost.

  The knitted glove according to the present invention is knitted as a whole with a conductive molding yarn containing conductive fibers in at least one of a core yarn and a flower yarn, and has conductivity in all parts, so that the tip of the thumb or index finger In addition to being able to perform operations by touching the touch panel to the touch panel, the softness, warmth, or softness that is the inherent characteristics of the Mole yarn has a good feeling of wearing. is there.

1 is a perspective view of a conductive molding yarn M according to the present invention. It is a perspective view in the state where touch panel operation is carried out with a hand wearing a glove G knitted as a whole by the conductive molding yarn M according to the present invention.

  First, with reference to FIG. 1, the conductive molding yarn M of the present embodiment will be described. The conductive molding yarn M of the present embodiment has a shape in which a core yarn 1 and an adhesive fiber 2 as a binder yarn are twisted together, and different types of flower yarns 3a and 3b are present between the two yarns 1 and 2. The core yarn 1 and the flower yarns 3a and 3b are bonded and fixed via the adhesive fibers 2 so that the flower yarns 3a and 3b are fixed to the core yarn 1 so as not to be displaced.

  The core yarn 1 and the flower yarn 3a are the same yarn of 70 denier, and contain only 20% of the conductive fiber with respect to the nylon yarn. The conductive fiber is a fiber in which nano-sized metal particles are compounded, and for example, “Kuraron EC (trade name)” related to the manufacture and sale of Kuraray Co., Ltd. can be used. This “Claron EC (trade name)” is a polyvinyl alcohol (PVA) fiber in which copper sulfide nanoparticles are finely formed inside the fiber. On the other hand, the flower yarn 3b is a polyester yarn containing only 40% of the above-mentioned conductive fiber “Claron EC (trade name)”.

  The above-described conductive molding yarn M can be manufactured by a manufacturing method using a conventional molding twisting machine, and while supplying only a plurality of adhesive fibers 2 along the core yarn 1, the core yarn 1 and the adhesive fibers 2 are provided. The yarns 3a and 3b are alternately wound around the yarns, twisted while cutting the flower yarns 3a and 3b with a cutter to form a molding, and then heat treated at a temperature at which the adhesive fibers 2 melt. It can be obtained by adhering and fixing the flower yarns 3a and 3b to the core yarn 1 so as not to fall off.

  As another production method, an adhesive fiber is blended in the core yarn, the flower yarn is wound around the core yarn, the flower yarn is cut by a cutter, and then the heat treatment is performed on the core yarn by heat treatment. There is also a method of bonding and fixing so as not to drop off.

  The conductive molding yarn M described above is a knitted product knitted with the conductive molding yarn M because both the core yarn 1 and the flower yarns 3a and 3b include conductive fibers in which nano-sized metal particles are combined. Is a knitted product knitted with conductive fibers in which copper sulfide is chemically bonded to resin fibers, and conductive fibers in which micron-sized carbon black is kneaded or electroless plating is applied to the surface of the fibers. Unlike the yarn, it has a soft feeling, a warm feeling or a soft feeling that is inherent to the molding thread, so that the wearing feeling is good.

  In particular, when the entire five-finger glove G (see FIG. 2) is knitted with the above-described conductive molding yarn M, the capacitance-type mobile phone is worn by the conductivity of the conductive molding yarn M while being worn on the hand. While touch panel operations such as telephones are possible, the glove has the above-mentioned characteristics inherent to the molding thread, even though the entire glove is knitted with the conductive molding thread M. Very good. In addition, since the entire glove is knitted with the conductive molding yarn M, it cannot be distinguished from the normal heat-insulating glove, so only the tip of the thumb bag and / or index finger bag is knitted with conductive fibers. It does not recognize special gloves like conventional gloves that allow touch panel operation.

  Then, as shown in FIG. 2, it is possible to operate the touch panel P of the touch panel mobile phone T with the fingertip of one hand while wearing the glove G in both hands.

  In addition, when a clothing-related product that is directly attached to a human body such as a muffler other than gloves and socks is knitted with the above-described conductive molding yarn M, electrostatic and electrification can be prevented and it becomes easy to use.

  Moreover, although two types of flower yarns 3a and 3b having different materials and conductive fiber contents are used for the above-described conductive molding yarn M, one type may be used. In the case of knitting gloves with the conductive molding yarn of the present invention, when the touch panel operation is possible by including the conductive fiber only in one of the core yarn 1 and the flower yarn 3a, 3b, this structure may be used. Good. When knitting gloves, the ratio of the conductive fibers contained in the core yarn and / or the flower yarn is based on having a conductivity that allows touch panel operation.

  In the above embodiment, the conductive fibers included in the core yarn 1 and the flower yarns 3a and 3b are polyvinyl alcohol (PVA) fibers in which copper sulfide nanoparticles are finely formed inside the fibers. The core yarn 1 and the flower yarns 3a and 3b are used as conductive fibers using fibers that are chemically bonded to impart conductivity and metal plated fibers that are provided with conductivity by electroless plating on the surface of the fibers. It can also be included.
