Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a woolen fabric for formal wear using a core yarn containing animal fibers from which scale has been removed.
[0002]
[Prior art]
Animal fibers such as wool have a scale, so that they are difficult to perform uniform dyeing, particularly dark dyeing, and there is a problem of shrinkage due to entanglement of fibers in washing and the like.
Therefore, attempts have been made to remove the scale of animal fibers by chlorination treatment or the like, to smoothen the fiber surface, to impart shrinkage resistance and to improve dyeability. However, since this type of fiber has a smooth surface, it tends to cause misalignment when woven, and a high-quality woven fabric cannot be obtained, so it is only partially used for knitting. It was.
[0003]
Animal fibers, on the other hand, have excellent physical properties and good texture, so it is required to use formal wear. However, animal fibers that leave normal scales have problems with dyeing properties as described above. In addition, even if it can be dyed to a certain degree of color, there is a problem that dust tends to adhere to the surface, and a satisfactory product cannot be obtained.
[0004]
Japanese Patent Application Laid-Open No. 2001-115351 describes one obtained by winding a shrink-proof yarn obtained by removing the scale of wool with an alkali or the like around a stretchable filament yarn (spandex yarn or the like). However, this is intended to provide a stretchable core yarn that has good washability and does not expose the core yarn. Due to the nature of the stretchable core yarn, its use is limited to knitted fabrics. (See [0007]). As a matter of course, there is no description regarding the core yarn other than the stretchable filament yarn in this publication.
[0005]
[Problems to be solved by the invention]
The present invention uses animal fibers such as wool, is excellent in dyeability and shrinkage resistance, does not cause misalignment, and is difficult to get dust on the surface, such as formal wear, and has antistatic properties and electromagnetic wave shielding properties. It is another object of the present invention to provide a good quality wool fabric.
[0006]
[Means for Solving the Problems]
The present inventors have solved the above problems by providing a woolen fabric using a core yarn in which animal fibers from which scale has been removed are wound around a conductive filament yarn.
[0007]
That is, in the present invention, the filament yarn having conductivity as a core yarn, a core yarn wrapped with animal fibers obtained by removing the scale around, by interweaving the at least a portion, using an animal fiber obtained by removing the scale On the other hand, it was possible to produce a high-quality woolen fabric with no misalignment, excellent shape stability, less dust on the surface, and excellent antistatic properties and electromagnetic shielding properties.
[0008]
First, the core yarn used in the woolen fabric for formal wear of the present invention was obtained by wrapping animal fibers before scale removal around a core yarn made of conductive filament yarn to produce a core yarn, and then performing scale removal treatment. However, the core yarn in which the animal fiber from which the scale has been removed in advance is wound around the conductive filament yarn can be dyed before the animal fiber is wound around the core yarn. Dyeing and dark color dyeing is possible, and even if metal is used for the core yarn, it is not affected by metal damage due to chemicals etc. during scale removal processing, and the antistatic effect is fully exhibited preferable.
[0009]
In the wool fabric for formal wear of the present invention, the core yarn does not necessarily need to be used 100% in the fabric, and can be woven with other yarns. Other yarns are not particularly limited, and those made of natural fibers or synthetic fibers can be used. However, in particular, when using yarns made of animal fibers from which scale has been removed, A product having a high slip prevention effect and a good texture can be obtained.
[0010]
For example , the wool fabric for formal wear of the present invention is preferably woven so that the core yarn is woven into the woven fabric so that at least one is present at a finishing density and at a distance of 2 cm or less, particularly 1 cm or less. In this case, the weaving density of the core yarn may vary depending on the background of the fabric.
[0011]
In the present invention, the presence of core yarn, mainly the weave, as other yarns, consisting of animal fibers obtained by removing the scale, even surface using a smooth yarn, without causing deviation in texture, stable You can get a finished product.
[0012]
The filament yarn used as the core yarn of the core yarn may be any material as long as it is conductive. For example, a yarn obtained by metal plating a synthetic fiber yarn such as nylon or polyester, or a metal such as stainless steel, copper or aluminum. Any yarn can be used, but from the viewpoint of the texture and weaving of the product, the filament made of synthetic fiber such as nylon or polyester is made of a metal with excellent conductivity (copper, silver, aluminum, nickel, chromium, etc.) Preference is given to using plated threads. In the present invention, by using a filament yarn having conductivity for the core yarn, it becomes possible to impart antistatic properties and electromagnetic wave shielding properties to the fabric.
[0013]
Core yarn and fineness of other yarn to be used for formal wear for woolen of the present invention can be the same, may be different, in a fabric for use in plain robe, etc., to have the same fineness Is preferred. In this case, it is possible to obtain a uniform product in which it is not apparent from the appearance that the other yarn and the core yarn are interwoven.
[0014]
The animal fibers removing the scale used in the present invention are removing scale, long animal fibers in shrink resistance, the method of removing the scales is not particularly limited. For example, chlorination method, chlorination / resin method, ammonium persulfate method, permanganic acid method (also called potassium permanganate / salt method or Neva shrink process), potassium permanganate / salt method, ozone method, plasma treatment Any of the products obtained by known methods such as protease treatment and combinations thereof can be used.
[0015]
Among them, the chlorination method is preferable because it has excellent dyeing power when pre-dyed.
[0016]
Various methods can be used as the chlorination method, and the classification on the machine equipment form includes PadAcid-DCCA processing method, Split Pad method, Kroy / resin method, Deep-In method, Woolcomber's SRW processing method, etc. According to the classification of chemical processing agents to be used, there is a method using an inorganic chlorinating agent such as a continuous hypochlorous acid method. Among them, the Split Pad method, which is a kind of continuous hypochlorous acid method, and the Kroy / Resin method is preferred.
[0017]
The animal fiber may be any of wool, mohair, cashmere, alpaca, vicuna, llama, camel, rabbit, etc., but in the present invention, the most easily available wool is used to produce a high-class product. Obtainable.
[0018]
The animal fibers from which the scale has been removed are preferably pre-dyed, and the material formed on the core yarn is then interwoven with other pre-dyed yarns. At this time, by dyeing the yarn used for the core yarn and the other yarns in the same color, it is possible to obtain a high-quality dark solid color having high utility value as formal wear or the like.
[0019]
The wool fabric for formal wear of the present invention may be one obtained by weaving a core yarn in which animal fibers before scale removal are wound around a conductive filament and then performing scale removal treatment. It is preferable to weave a core yarn in which animal fibers are wound around a conductive filament because not only after product production but also misalignment during weaving, scale removal process and dyeing process can be prevented.
[0020]
When animal fibers from which scale has been removed so as to cover 100% of the filament yarn having conductivity are wrapped around, conductive fibers such as metal plating yarn cannot be seen from the outside, for example, black formal and other garments look black. preferable.
[0021]
The structure of the woven fabric in the present invention is not particularly limited, and may be any plain weave, twill weave, or the like.
[0022]
