JP4798707B2 - Wig moisture-permeable material and wig or wig base cap having this moisture-permeable material - Google Patents

Description

  The present invention relates to a moisture permeable material suitable for wig use that has both moisture permeability and durability. Furthermore, the present invention relates to a wig or a wig base cap using the moisture-permeable material.

The wig to be attached to the head is a wig base that becomes a base molded into a head shape, and human hair or artificial hair is implanted in the wig base. Examples of the material of the wig base include artificial skin and A net made of a mesh-like woven or knitted fabric made of a non-porous thermoplastic resin film such as a urethane elastomer and a synthetic fiber is generally used. In the case of a wig base made of a nonporous thermoplastic resin film, the number of hairs to be planted and the interval between each hair to be planted can be freely set, so there is an advantage that a wide range of styles can be created, Since the moisture permeability is inferior, there is a drawback that unpleasant sensations such as stickiness, stuffiness, and itchiness are easily caused by sweating.

  On the other hand, in the case of a wig base made of a mesh-like woven or knitted fabric, there are a number of gaps in the woven or knitted fabric, so the moisture permeability is markedly improved compared to a nonporous thermoplastic resin film. The hair can be planted only on the synthetic fiber filaments constituting the mesh woven or knitted fabric, the number of hairs that can be planted by the mesh shape, and the spacing between each hair to be planted is limited, so the styles that can be produced are limited. There is a drawback, and a wig base material that combines the advantages of a thermoplastic resin film with the advantages of a mesh has been desired.

In order to realize these, for example, in Patent Document 1, a moisture permeability of 500 to 500 having a multilayer structure of a polyurethane elastomer using a poly-α-amino acid derivative and a woven or knitted fabric such as nylon stockings as a reinforcing material is used.
A sheet of 2000 g / m ² · 24 hr is further disclosed in Patent Document 2 in which a moisture permeability of 5000 to 6000 g / A wig base fabric of m ² · 24 hr is disclosed.
When the wig is attached to the head, the moisture permeability that allows the head to be comfortably attached without stuffiness is required to be 8000 g / m <24 hr or more according to the JIS L-1099A method. , 2 does not satisfy any moisture permeability. Generally, if the thickness of the material is reduced, the moisture permeability tends to be improved, but the strength is lowered and it is difficult to achieve both.

In the case of wigs, artificial hair or natural hair is hooked on the heel of the heel needle with a sharp tip on the base wig base, inserted, and bound. The hair is required to have such strength that the wig base material is not damaged when the hair or natural hair is implanted. However, there is no specific disclosure about the strength of the material in the patent documents.
In addition, there is no problem in the case of a wig intended to hide thin hair, but in the case of a fashion wig, the wig wearer wears his / her own hair. Since it was necessary to store the inside of the head, the head was partially raised after wearing, and conversely, it was dented. In order to prevent such an adverse effect, Patent Document 3 discloses a ground net that covers the head as a ground before wearing a wig. The base net is required to have a light weight feeling and sufficient moisture permeability that does not cause stuffiness during deposition, but no specific disclosure has been made regarding the moisture permeability of the base net or stuffiness of the head during deposition.

This invention improves the subject of the wig described in the said patent document etc., and is providing the wig provided with the outstanding moisture permeability which is easy to attach.

In order to achieve the above object, the moisture-permeable material for wigs of the present invention comprises (1) a porous polyurethane as a core material and a mesh layer made of synthetic fibers or natural fibers on one side, It is a three-layer structure formed by laminating a fiber layer made of synthetic fiber or natural fiber on the other side, and the moisture permeability of the three-layer structure is 8000 g / m ² · 24 hr or more by JIS L-1099 A method. A moisture-permeable material for wigs having a strength of 90 N / inch or more and a tear strength of 15 N or more.

(2) The moisture-permeable material for wigs according to (1), wherein the mesh layer is formed of polyester fibers, and the fiber layer is formed of a mesh composed of nylon fibers.

(3) The moisture-permeable material for wigs according to (1) or (2), which is used as a part of a wig base formed into a head shape.

(4) The base cap is characterized in that the base cap deposited under the wig is made of the moisture-permeable material for wigs described in (1).

(5) In the wig base of the wig, the main member forming the wig base and the moisture-permeable material for wigs described in (1) are integrally formed by sewing or bonding. It is.

(6) A base cap for wigs characterized in that one or more of the moisture permeable materials for wigs according to (1) are formed into a head shape or joined together to form a head shape. It is.

According to the moisture permeable material for wigs of the present invention, since one side of the porous polyurethane is coated with a mesh such as polyester, the moisture permeability is very excellent. Since the mesh member to which the other surface is implanted uses nylon fibers, it has excellent durability and smoothness. Thus, it is possible to provide a moisture-permeable material for wigs that has a three-layer structure and is excellent in moisture permeability.

The porous polyurethane used for the moisture-permeable material for wigs of the present invention is generally produced by a dry method or a wet method. As the wet method, a water-miscible organic solvent solution of a polyurethane resin is applied onto a release material. Thereafter, the polyurethane resin is solidified by dipping in water. On the other hand, as a dry method, there are a method using a foaming agent and a filler, and a method of preparing a water-based emulsion of a polyurethane resin by using a difference between boiling points of water and a solvent. It may be manufactured by mixing hollow resin particles or by a method as described in JP-A-2004-315817, and is not limited. The thickness is preferably 0.005 to 0.01 mm. Further, the moisture permeability is preferably 10000 g / m <2> .24 hr or more according to the JIS L-1099A method.

As the porous polyurethane used for the moisture-permeable material for wigs of the present invention, a polyurethane resin-based resin composition added with inorganic whiskers to form a sheet can be used. This polyurethane resin-based resin composition contains 50 to 100% by weight of polyurethane resin, and other resins may be mixed with this polyurethane resin. The polyurethane resin can be produced by using a polar organic solvent to form a sheet having a polyurethane resin concentration of 15 to 40% by weight.
The adhesive resin that bonds the porous polyurethane layer and the fiber structure must be able to maintain the adhesive strength for a long period of time under a humidity condition of 50% or more, such as ethylene vinylene acetate, synthetic rubber, or moisture curing Resins called hot melts such as type polyurethane can be used. This adhesive resin is preferably applied in the form of dots or biases instead of being applied to the entire surface of the porous polyurethane sheet. If the adhesive resin is applied to the entire surface, the moisture permeability of the porous polyurethane is deteriorated. Furthermore, it is not preferable because holes are made in both the fiber structure and the porous polyurethane during flocking. The coating amount, 10 to 100 g / m ² is preferred. If the coating amount is less than 10 g / m ² , it may not be able to withstand long-term use and may be peeled off, and if it is 100 g / m ² or more, the flexibility is impaired and the weight increases, making it difficult to use for wigs.

The mesh-like mesh layer laminated on the porous polyurethane used for the moisture-permeable material for wigs of the present invention is used on the side that comes into contact with the head and can suppress the stickiness and stuffiness of the scalp. It is preferable that it gives a refreshing feeling in appearance. For example, synthetic fibers such as polyester and nylon, natural fibers such as cotton and silk, regenerated fibers such as rayon and cupra, and semisynthetic fibers such as triacetate and diacetate can be used. A mesh layer formed of polyester or nylon fibers is preferred as it is lightweight and can withstand durability and washing.

The polyester mesh used in the present invention is preferably made of polyethylene terephthalate fiber, and has a mesh roughness of 180 to 500 mesh, which is difficult to recognize as a wig at a distance. For example, a polyester mesh knitted fabric with a basis weight of 60 to 70 g / m &sup;; and a thickness of 0.20 to 0.30 mm is preferable. The yarn constituting the polyester mesh may be a twisted yarn of a polyester yarn and another synthetic fiber yarn. The reason why the basis weight is in the range of 60 to 70 g / m <2> is that the head shape formed by rounding the wig base due to the weight of the hair material collapses after planting the hair if the basis weight is less than 60 g / m <2>. The shape of the head curve may be lost, and if the basis weight is larger than 70 g / m <2>, the weight of the polyester mesh may be increased and the wig base periphery may be turned up. Furthermore, the weight of the wig base itself becomes heavy and becomes a burden when the wig is mounted. On the other hand, if the thickness is less than 0.20 mm, the gap between the wig and the head disappears when the wig is worn, and the head comes into contact with the porous polyurethane, so that the moisture permeability decreases. If the thickness is greater than 0.30 mm, the entire wig becomes thick, and when the wig is worn, there is a risk that the wig will appear as if the wig floats due to a step between the peripheral edge of the wig and the head.

Further, the fiber layer laminated on the other surface of the porous polyurethane is for implanting artificial hair or natural hair on the surface, and the fiber layer is preferably a mesh that can be easily implanted, and the fibers used are not particularly limited. Nylon fiber is preferable, and nylon 6.6 fiber is particularly preferable. In general, nylon fibers are soft and difficult to fold, and even if they have folds, it is easy to correct, so it is possible to correct even if the shape of the wig base molded into the head shape collapses, It is preferably used as a wig-based material. The mesh shape to be used is preferably a honeycomb shape, and the size thereof varies depending on the amount of the own hair of the wearer. For example, a relatively thin person has a side length of 1 to 2 mm, and is less than 1 mm where no hair exists. The basis weight of the knitted fabric is 20 to 30 g / m <2>, and the thickness is 0.20 to 0.35 mm.
If the basis weight is less than 20 g / m 2, the hair material cannot be sufficiently bound to the fiber layer at the time of flocking, and the binding strength is lowered. Further, during the flocking operation, not only the fiber layer but also the porous polyurethane resin underneath is penetrated, and a hole is made in the porous polyurethane. When the basis weight is larger than 30 g / m <2>, the weight of the entire wig becomes heavy, and the fiber layer tends to contain moisture and becomes heavier particularly in a high humidity environment.
On the other hand, the thickness is in the range of 0.20 to 0.35 mm when the wig is worn, the boundary between the peripheral edge of the wig and the head does not become a step, and the thickness of the wig does not appear to float. 0.45 to 0.70 mm, and in the three-layer moisture-permeable material of the present invention, the thickness of the porous polyurethane layer is 0.005 to 0.01 mm, and the thickness of the polyester fiber layer of the network layer is 0. When the hair material is planted in the fiber layer at 20 to 0.30 mm, the thickness of the fiber layer where the fixed part of the hair material can be seen naturally should be thicker than 0.20 mm, but the total thickness of the wig is considered Then, it is preferable that the thickness of the nylon fiber of the fiber layer is 0.20 to 0.35 mm.

As a nylon mesh member, a first plane composed of a warp group in which a plurality of nylon filaments are arranged in the longitudinal direction and a second plane composed of a weft group in which a plurality of nylon filaments are arranged in a direction orthogonal to the warp group are overlapped. In addition, it is possible to use one formed by welding the intersections of the filaments.
In the method of planting hair material of artificial hair or natural hair in a wig base, an acupuncture needle having a sharp tip is passed through the wig base, and the hair material is hooked and inserted through the wig needle for binding. When this hair needle is penetrated through the wig base and the hair material is hooked, the hair needle is pulled with a strong force, so if the fiber layer to which the hair material is implanted does not have a certain degree of elasticity, the wig base will be damaged or the wig base will wave Nylon 6 and 6 having elasticity are preferable.

One or a plurality of moisture-permeable materials for wigs configured in this way are fixed to a male mold such as gypsum, and resin is applied and molded, or the head is joined by a method such as sewing or bonding It can be formed into a shape to form a wig base or a wig base cap.
The moisture permeable material for wigs can be used as at least a part of a wig base or a wig base cap.

The conventional moisture-permeable material for wigs is JIS
Since the water vapor transmission rate by the L-1099A method is 8000 g / &#8575;&sup2; · 24 hr or less, there is a risk of stuffiness when worn on the head for a long period of time, which is not preferable.
The moisture-permeable material for wigs preferably has a tensile strength of 90 N / inch or more and a tear strength of 15 N or more. If the tensile strength is less than 90 N / inch and the tear strength is less than 15 N, there is a risk of damage in the manufacturing process. Furthermore, there was a risk of cracking due to inability to withstand several times of attaching and detaching operations to the head.
When wearing a wig, align the wig to the front, back, left, and right of the head, and fix the wig to the head by means such as pinching the hair with an adhesive or a pin. Fixing to the position makes it possible to fit the head. When the tensile strength of the material used as the wig base is less than 90 N / inch, it is damaged when the wig is attached, or the durability is lowered, so that it cannot be used repeatedly. Also, if the tear strength is less than 15N, a hole is formed when the hair needle for planting the hair material into the wig base is penetrated, and the hair material cannot be bound to the base. However, the binding force is weak, and the hair material will fall off due to the brushing of the style set, etc., so it cannot withstand normal use.

Artificial hair was implanted into the artificial skin portion and the mesh fiber layer surface of the nylon fiber of the net-like member 21 to form a partial wig. The physical properties and performance of the wig of Example 6 are shown in Table 1.

(Comparative Example 1)
The tensile strength and tear strength are the same as those of Example 1 with the same three-layer structure as in the present invention, but the moisture permeability is 7000 g / &#8575;&sup2; .24 hr according to JIS L-1099A method. A wig base was produced in the same manner as in Example 2. A hair material was further planted on the base net to produce a wig. Table 1 shows the physical properties and performance of the wig of Comparative Example 1.

(Comparative Example 2)
A three-layer structure similar to that of the present invention, having a moisture permeability of the same level as in Example 1, but using a moisture-permeable material having a tensile strength of 80 N / inch and 55 N / inch and a tear strength of 16 N and 14 N. A wig base was produced in the same manner as in Example 2. A hair material was further planted on the wig base to prepare a wig. The physical properties and performance of the wig of Comparative Example 2 are shown in Table 1.

(Comparative Example 3)
The porous urethane was the same as that of the present invention, and a wig base was produced in the same manner as in Example 2 with a moisture-permeable material having a two-layer structure in which a polyester mesh layer was laminated on the porous urethane. A hair material was further planted on the wig base to prepare a wig. Table 1 shows the physical properties and performance of the wig of Comparative Example 3.

(Comparative Example 4)
The porous urethane was the same as that of the present invention, and a wig base was produced in the same manner as in Example 2 with a moisture-permeable material having a two-layer structure in which a nylon fiber layer was laminated on the porous urethane. A hair material was further planted on the wig base to prepare a wig. Table 1 shows the physical properties and performance of the wig of Comparative Example 4.

(Comparative Example 5)
A 55 mesh / inch net of polyester filament with a diameter of 0.12 mm is fixed to a male head-shaped mold with a staple using a gun tucker, and a two-component urethane thermosetting resin (manufactured by Nissin Resin Co., Ltd., After applying a solution obtained by diluting ADAPT E-No. 2) with an organic solvent from the top of the net, heat treatment was performed at 100 ° C. for 10 hours to prepare a base cap for wigs. Table 1 shows the physical properties and performance of the wig base cap of Comparative Example 5.

Table 1 shows the evaluation of the state of the wig after the hair material was planted on the wig base produced in Examples and Comparative Examples 1 to 4 and the state when the wig was mounted.

In Comparative Example 1, there was no problem with the strength of flocking, but when the wig was put on, the head became muddy in a short time. In Comparative Example 2, damage to the planted part was observed and the appearance of the wig was inferior, but when the wig was worn, the moisture permeability was good without stuffiness. Since Comparative Example 3 does not have a fiber layer which is a place to plant the hair material, since the hair is planted in the porous urethane layer and the polyester mesh layer therebelow, the porous urethane layer has a hole in the hair material. Can't bind. On the other hand, since the hair material was wound around the polyester mesh and bound to the polyester mesh layer, the hair material hit the head and felt pain when the wig was worn. Since Comparative Example 4 has a fiber layer that is a place to plant the hair material, the hair can be planted, but the wig base itself is weak, so the base is damaged, and the binding strength of the hair material is weak, so it can be used in normal use. Hair material falls off. Furthermore, since the polyester mesh layer is not attached, when the wig is attached, the head directly touches and adheres to the porous polyurethane layer, so that the sweat is accumulated between the head and the porous polyurethane, which is uncomfortable.

  When the base cap of Comparative Example 5 is worn for a long time, the temperature of the head rises and stuffiness occurs. When the wig was attached after the cap was put on, the wig was unstable and floated because the base cap and the wig did not fit.

Moreover, the moisture-permeable material for wigs of this invention can also be produced in various shapes as described above. In addition, it can be used as follows.
For example, a band-shaped body made of synthetic fiber or the like is stretched vertically and horizontally, and the intersection is fixed by sewing or bonding with an adhesive to produce a head-shaped cap. Next, artificial hair or natural hair is sewn with a sewing thread using a sewing machine or the like to make a mino hair, and a band-shaped body constituting a cap in which the mino hair is formed into a head shape is sewn to the cap. The hair can be attached, and the moisture-permeable material for wigs can be used by being sewn or fixed in place with an adhesive or an adhesive.

As the moisture-permeable material for wigs of the present invention, it is possible to color the porous polyurethane or nylon fiber layer by mixing a colorant or the like.
