Description

  In the present invention, a sewing thread (linking thread) used at the time of sewing a clothing product is a thread using a synthetic fiber having antistatic performance and dyeable, and relates to a garment having antistatic performance using the same thread.

In recent years, air conditioning equipment has been improved, and the working room is maintained at a comfortable temperature, but the humidity is set low. In winter, the humidity is low both indoors and outdoors.
In the warm clothing used in winter, static electricity tends to be accumulated in the clothes due to the activities of the wearer, and electrostatic discharge during undressing leads to discomfort. It has been known to suppress static electricity by applying anti-static processing to clothing products, but the anti-static function decreases with repeated washing. There is also a method of containing fibers with antistatic performance in the woven or knitted fabric, but the fibers with antistatic performance are colored fibers containing carbon, titanium oxide, and metal substances, and they have vivid colors even when dyed. Since a knitted fabric cannot be obtained, there is a demand for the development of a woven or knitted fabric that maintains antistatic performance without degrading the quality of clothing products.

  Patent Document 1 describes a sewing thread obtained by further twisting at least one composite yarn composed of a covering configured to be a conductive fiber in the sheath and a thermoplastic fiber in the core. However, since the sheath is covered with conductive fibers, the same color at the time of dyeing is lacking.

  Patent Document 2 describes that an antistatic garment is obtained by stitching woven fabrics containing conductive fibers with yarns containing conductive fibers. Conventionally, antistatics of knitted fabrics containing conductive fibers have been described. The performance is known.

In the garment of the present invention, the sewing thread used is preferably a spun yarn.
By configuring the sewing thread as a spun yarn, the conductive fibers can be distributed not only on the surface of the yarn but also on the whole, and the content of the conductive fibers relative to the sewing thread can be changed by the amount of triboelectric charge. Further, since short fibers are used, the end portions of the conductive fibers are increased, and corona discharge can be performed efficiently.

The single fiber fineness of the conductive fiber is preferably 1 dtex to 15 dtex.
If the single fiber fineness of the conductive fiber is 1 dtex or more, the spun yarn count can be reduced. If it is 15 dtex or less, the yarn strength at the time of producing spun yarn can be secured, which is preferable. From the viewpoint, 3 dtex to 11 dtex are more preferable.

(Spun yarn)
The spun yarn used in the present invention can be obtained by a general cotton spinning or worsted spinning method. The fibers constituting the spun yarn include conductive fibers, preferably a core-sheath type acrylic fiber, in an amount of 30 to 100% by mass with respect to the spun yarn, and further mixed with other fibers. As the blended partner at this time, acrylic fiber and polyester fiber are preferable for maintaining the yarn strength of the spun yarn, and when creating a yarn having a metric count of 90 or more, the polyester fiber is more preferably a blended partner. .

(Core-sheath acrylic fiber)
Below, suitable embodiment in the manufacturing method of the conductive acrylic fiber of this invention is described in detail.
In the method for producing a conductive acrylic fiber according to this embodiment, first, a sheath component spinning dope and a core component spinning dope are prepared. An organic solvent solution in which an acrylic polymer is dissolved in an organic solvent is prepared as the spinning solution for the sheath component, and the conductive fine particle (A) and the acrylic polymer (B) are used in a weight ratio as the spinning solution for the core component. An organic solvent solution prepared by mixing (A) / (B) so as to be 4 or more and 20 or less and dissolving in an organic solvent is prepared.

  In the present embodiment, the acrylic polymer used for the spinning solution of the sheath component and the core component is not particularly limited, and a general acrylic polymer used for the production of conventional acrylic fibers can be used. In particular, it is preferable to use a material that can easily exhibit heat shrinkage in the heat shrinkage treatment step after spinning described below. The relationship between the thermal shrinkage due to the composition and relaxation of the acrylic polymer depends on the monomer component to be copolymerized, but in general, the smaller the acrylonitrile content in the polymer, the higher the heat shrinkability. is there. Therefore, it is desirable to appropriately adjust the acrylonitrile content in the spinning dope so that a predetermined heat shrinkage rate can be obtained in the subsequent heat shrink treatment process.

  In particular, for the spinning solution of the sheath component, it is preferable that the acrylonitrile content of the acrylic polymer is 50% by weight to 98% by weight, particularly 50% by weight to 95% by weight. If the acrylonitrile content is less than 50% by weight, the original characteristics of the acrylic fiber such as dyeing vividness and color developability are not effectively exhibited, and other physical properties such as thermal properties tend to be lowered. . In order to improve the solubility and dyeability of acrylonitrile, it is preferable to copolymerize acrylonitrile with an unsaturated monomer such as an acrylate ester.

  Therefore, the acrylonitrile content in the sheath is preferably 50% by weight or more and 98% by weight or less as described above by copolymerizing the unsaturated monomer. Without losing the properties it has, it can have excellent dyeing clarity, color development and thermal properties. In the present embodiment, the unsaturated monomer copolymerized with acrylonitrile is not particularly limited. For example, acrylic acid and acrylic acid esters, methacrylic acid and methacrylic acid esters, vinyl acetate, vinyl chloride, vinylidene chloride, and the like. Can be used.

  Also, in this case, in order to stably manufacture the acrylic fiber having a core-sheath structure without suppressing the core part from being exposed to the sheath part and causing yarn breakage during yarn, It is extremely important to control the viscosity of the sheath component, and the solid content concentration and temperature in the spinning component solution of the sheath component are important so that the viscosity of the spinning component solution of the sheath component is 300 poise or less, preferably 150 poise or less. is there.

  On the other hand, the spinning solution of the core component is mixed so that the weight ratio (A) / (B) of the conductive fine particles (A) and the acrylic polymer (B) is 4 or more and 20 or less as described above. Dissolve in organic solvent. By setting the value of the above weight ratio (A) / (B) to 4 or more, when a conductive acrylic fiber is produced, a continuous phase of conductive fine particles is stably formed in the acrylic fiber, and sufficient conductivity is achieved. Performance can be provided. On the other hand, if the weight ratio (A) / (B) exceeds 20, the dispersion of the conductive fine particles and the spinnability of the spinning dope will be reduced during spinning, and when the coagulated yarn is taken up. Or it becomes easy to generate | occur | produce the cutting | disconnection of a core part at the time of extending | stretching. For this reason, the spinnability is lowered and the conductive performance of the acrylic fiber is lowered.

At this time, it is preferable that the conductive fine particles contained in the core component spinning dope is a metal oxide having a high whiteness in which the electrical conductivity in a powder form is 10 ⁻³ S / cm or more. As such conductive fine particles, titanium oxide or zinc oxide can be suitably used. In addition, for example, titanium oxide whose surface is coated with tin oxide, indium oxide, tin oxide or zinc oxide can be used. it can. In order to further increase the conductivity, antimony oxide can be used in combination with tin oxide and indium oxide, and tin oxide, indium oxide, aluminum oxide, potassium oxide, germanium oxide, and the like can be used in combination with zinc oxide. In this case, the form of the conductive fine particles to be contained in the spinning dope is not particularly limited, but when the fine particles are granular, the average particle size is 3 μm or less. It is preferable from the viewpoint of stability.

  In addition, as for the organic solvent for adjusting each spinning stock solution of the sheath component and the core component, an organic solvent such as dimethylacetamide, dimethylformamide, dimethylsulfoxide can be preferably used, but is not particularly limited. Other organic solvents commonly used in acrylic fiber spinning can also be selected.

  In the present embodiment, there is no particular limitation on the solid content concentration and temperature of each spinning solution of the sheath component and the core component, but if the solid content concentration is too low, voids are likely to occur in the fiber after spinning. As a result, the physical properties of the fibers and the conductive performance may be reduced. Therefore, the solid content concentration in the spinning stock solution of the sheath component is preferably 5% by mass or more, and the solid content concentration in the spinning stock solution of the core component is preferably 30% by mass or more.

  Next, the spinning solution of the sheath component and the core component prepared as described above has a content of conductive fine particles contained in the acrylic fiber using a core-sheath type spinneret of 5 mass% or more and 15 mass% or less. Thus, the ratio of the sheath portion to the core portion is set so that spinning is performed by a wet spinning method. When performing spinning, if the content of conductive fine particles contained in the fiber is less than 5% by mass, the conductive fine particles provide less excellent conductive performance for acrylic fibers because of the small amount of conductive fine particles. I can't. On the other hand, when the content of the conductive fine particles exceeds 15% by mass, since the fiber whiteness is inferior when the conductive acrylic fiber is produced, there arises a problem that the use of the product is limited.

  The wet spinning method can be carried out in the same manner as that generally used in the production of conventional acrylic fibers. For example, a sheath stock and a spinning solution of a core component are organically fed from a core-sheath spinneret. Spinning can be performed by discharging and solidifying into a coagulating liquid comprising a solvent and water.

  At this time, as the core-sheath type spinneret, it is preferable to use a spinneret having a number of holes of 3000 or more, particularly 5000 or more. Thus, the core-sheath type spinneret having a number of holes of 3000 or more is used for spinning. By doing so, conductive acrylic fibers can be produced with very high productivity.

  The coagulated yarn obtained by the above wet spinning is then subjected to various treatments such as drawing, solvent removal, oiling, drying and densification, and then the coagulated yarn is contracted at a shrinkage rate of 30% or more and 50% or less. A heat shrinking process for shrinking is performed. The treatment method and treatment conditions in each treatment such as stretching, solvent removal, oil agent application, and drying densification are not particularly limited, and can be appropriately changed as necessary. For example, the stretching treatment can be performed while removing the solvent in hot water at 80 ° C. or higher, and considering the spinning stability and the physical properties of the fiber obtained, the stretching ratio is 3 to 10 times. Is preferably set to 4 to 7 times.

  Hereinafter, the present invention will be specifically described by way of examples. In addition, the evaluation item in an Example was measured with the following method.
