Definitions

  • This invention relates to a wig such that its wearing is not easily visible by controlling the bending rigidity of the hair attached to its wig base for the better blending with the wig wearer's own hair growing on the scalp.
  • a wig comprises basically in general a wig base with a net material as its main part or a wig base of an artificial skin made of a thin sheet or film of polyurethane or silicone, and hair attached to said wig base by sewing or bonding.
  • the hair attached to a wig base besides natural hair such as human hair, the artificial hairs made of polyamide resins, polyester resins, or modacryl are known.
  • the cap-shaped wig for a whole scalp which has a periphery along the wearer's hairline on the forehead, side head, and rear head portions, and the partial wig to be worn to hide only the necessary portion of the head are known in general.
  • Patent Reference 1 discloses that various hair styles are available by partitioning a scalp to a plurality of portions, wearing partial wigs on respective portions, and exchanging a part of the plurality of partial wigs with other partial wigs, changing the positions for wearing on the scalp, or by changing the direction of wearing.
  • Natural hair has been fondly used since ancient times as the hair attached to a wig base as mentioned above, but there are many cases recently that, from restriction of supply of natural hair material, acrylic, polyester, polyamide synthetic fibers, for example, are used as the hair material for a wig.
  • acrylic, polyester, polyamide synthetic fibers for example, are used as the hair material for a wig.
  • polyamide fibers have appearance and physical properties similar to natural hair in many aspects, they have so far been in practical use, and especially, excellent wigs can be provided by the invention of the present applicant which removes unnatural gloss by surface treatment (See Patent Reference 2.).
  • polyacrylic fibers have low melting point and poor heat stability, so that they have such weak points as poor shape preservation after permanent wave setting, resulting in distortion of setting, for example, such as curl and the like when disposed in warm water.
  • Polyester fibers excel in strength and heat stability, but have too high bending rigidity, in addition to extremely low moisture absorbency compared with natural hair, resulting in appearance, tactile feeling, or physical properties different from natural hair, for example, in the environment of high humidity, and they give markedly uncomfortable feeling when used for wigs.
  • This bending rigidity is defined as the reciprocal number of curvature change generated when a unit bending moment is applied to artificial hair. The larger the bending rigidity of artificial hair, the less bendable, the more resistant to bending, that is, the harder and the less bendable is artificial hair. In other words, the smaller the bending rigidity, the more bendable and softer is artificial hair.
  • Said bending rigidity is the property relating to such feeling as tactile and texture of fibers, and is widely recognized in fiber and textile industries as such that capable of numerical expression by KAWABATA method of measurement (See Non-Patent Reference 1.). Also, an apparatus has been developed which can measure the bending rigidity using a single strand of fiber or hair (See Non-Patent Reference 2.).
  • Polyamide fibers include linear saturated aliphatic polyamide in which only methylene chains are connected with amide bond as a main chain, for example, such as nylon 6 and nylon 66, and semi-aromatic polyamide in which phenylene units are included in the main chain, for example, such as nylon 6T of TOYOBO, LTD. and MXD6 of MITSUBISHI GAS CHEMICAL COMPANY, INC.
  • Patent Reference 2 discloses surface-treated artificial hair of nylon 6 fiber as the material, but only nylon 6 fiber has the bending rigidity lower than natural hair as the property relating to such feeling as tactile and texture, and hence it is difficult to manufacture the artificial hair of the same property as natural hair.
  • nylon is a trademark of du Pont
  • nylon is a trademark of du Pont
  • the artificial hair using nylon 6T has the bending rigidity higher than the natural hair, and hence it is difficult to manufacture the hair of the same property as natural hair. Therefore, it might be considered to manufacture the fiber having the bending rigidity close to natural hair by melt-spinning of nylon 6 and nylon 6T, but these two resins have too different melting points, and if melt temperature is determined fitting to nylon 6T of higher melting point, then there is too serious a problem in the manufacturing process that nylon 6 having low melting point and relatively poor heat stability is deteriorated by thermal oxidation during melting and, consequently, excellent artificial hair can not be obtained.
  • the fiber of sheath/core structure is known as the method to utilize both properties of two kinds of resins.
  • Said fiber comprises a core fiber and a sheath fiber surrounding it, and has been reported as a generic fiber, or artificial hair material for wigs, by utilizing respective properties of different two kinds of resins.
  • Patent References 3 and 4. disclose the fiber of sheath/core structure made of vinylidene chloride, polypropylene, and others, and Patent Reference 4 discloses a polyamide, but modified fiber by blending protein bridged gel into the core part.

  • artificial hair used for a wig is primarily required to have feeling close to natural hair (appearance, ductile and texture feeling) and physical properties, and, in addition, ideally to have physical properties superior to natural hair.
  • various synthetic fiber materials have their own merits and defects, and, among them, certain polyamide fibers are now in practical use owing to their excellent properties.
  • a wig is made by attaching artificial hair made of a polyamide fiber material to a wig base
  • bending rigidity of a polyamide fiber is too low compared with the wearer's own hair even if the wearer's own hair growing on the scalp and the artificial hair attached to a wig base are well blended and the hair style is well set upon the wig wearing
  • the wearer's own hair and the artificial hair attached to a wig are separated as time elapses since the wig wearing, the wearer's own hair around the wig base periphery stands up to cause unnatural style, resulting in easily visible wig wearing.
  • the hairs attached to a wig base are arranged in the same lengths regardless of the region of the wig base, or have a curl diameter different from that of the wearer's own hair, then the hairs of the wig can not be well shaped as a whole, and it takes time to set a hair style after the wig wearing.
  • An object of the present invention is, in view of the above-mentioned problems, to provide a wig which does not easily separate the wearer's own hair growing on the scalp and the hair attached to the wig, and which does not easily make the wig- wearing visible by well blending.
  • Another object of the present invention is to provide a wig which makes it possible for the wearer to easily set a desired hair style, and not to easily distinguish the wearer's own hair growing on the scalp and the hair attached to the wig.
  • one of the embodiments of the present invention is a wig comprising a wig base and hair attached to the wig base, characterized in that the hair attached to at least a periphery of said wig base has bending rigidity lower than natural hair.
  • the wig base is partitioned to a plurality of regions including a periphery of a left and right side head portion and a periphery of a rear head portion, the hairs attached to the partitioned regions of the wig base have bending rigidities pre-determined for the respective regions, and the hairs attached to said periphery have bending rigidities lower than natural hair.
  • the hair of higher bending rigidity than the hair attached in a periphery is preferably attached.
  • Said wig base is partitioned including at least a top portion as the center region of the wig base, the periphery, and an intermediate region zoned between the top portion and the periphery along said periphery, the hair attached to the top portion may have bending rigidity of substantially the same level as natural hair, the hair attached to the periphery may have bending rigidity lower than natural hair, and the hair having bending rigidity of substantially the same level as natural hair and the hair having bending rigidity lower than natural hair may be mixed and attached to the intermediate region.
  • the hairs attached to the partitioned regions of said wig base preferably have curl diameters and/or lengths pre-determined for the respective regions, and the hairs attached to said peripheries preferably have curl diameters and/or lengths of substantially the same level as the wearer's own hair growing on the scalp.
  • a wig of another embodiment of the present invention is characterized in that the wig base is partitioned to a plurality of regions including the total peripheral portion comprising a periphery of a forehead portion, a periphery of a left and right side head portion, and a periphery of a rear head portion, the hairs attached to the partitioned regions have bending rigidities pre-determined for the respective regions, and the hairs attached to the total peripheral portion have bending rigidities lower than natural hair.
  • Said regions are preferably partitioned including a top portion as the center region of the wig base, the total peripheral portion comprising the periphery of the forehead portion, the periphery of the left and right side head portion, and the periphery of a rear head portion, and an intermediate region zoned between said top portion and said total peripheral portion along said total peripheral portion, the hair attached to the top portion has bending rigidity of substantially the same level as natural hair, the hair attached to the total peripheral portion has bending rigidity lower than natural hair, and the hair having bending rigidity of substantially the same level as natural hair and the hair having bending rigidity lower than natural hair are mixed and attached to the intermediate region.
  • the hairs attached to the partitioned regions of the wig base have curl diameters and/or lengths pre-determined for the respective regions, and the hair attached to the total peripheral portion has a curl diameter and/or length of substantially the same level as the wearer's own hair growing on the scalp.
  • Hair preferably has a sheath/core structure comprising a core portion and a sheath portion covering said core portion, the core portion is made of a polyamide resin, the sheath portion is made of a polyamide resin having lower rigidity than the core portion, and bending rigidity is controlled by the mass ratio of the sheath portion and the core portion.
  • hair may be made by mixing a first artificial hair made of a polyamide resin and a second artificial hair made of a polyester resin in the pre-determined ratio, the first artificial hair has a sheath/core structure comprising a core portion and a sheath portion covering said core portion, the core portion is made of a polyamide resin, the sheath portion is made of a polyamide resin having lower rigidity than the core portion, and bending rigidity is controlled by the mass ratio of the sheath portion and the core portion.
  • the wig of the present invention is such that the hair attached to the periphery of the wig base has bending rigidity lower than natural hair, and the wearer's own hair growing on the scalp has bending rigidity equal to or lower than natural hair, so that, with the hair having bending rigidity of the same level as the wearer's own hair attached to the left and right side head and the rear head peripheries of the wig base, said hair and the wearer's own hair are well blended and both show similar standing up and curvature. Therefore, the wearer's own hair and the wig hair do not separate to show similar behavior. Also, since the hair having length and/or curl diameter pre-determined for each wig base region is attached in the wig of the present invention, only partial fine adjustment is required upon wearing said wig, and hence the hair style can be easily formed according to the wearer's preference.
  • the hair whose bending rigidity is controlled can be used by adjusting the mass ratio of a sheath/core structure with polyamide materials, adjusting the cross-sectional size with polyester materials, or adjusting the mixing ratio of polybutylene terephthalate as the incorporated feed material.
  • the wearer's own hair growing on the scalp that is, the remaining hair growing around except for the lost hair and the thin hair portions has bending rigidity lower than natural hair on average.
  • the hair attached to the periphery of the wig base has bending rigidity lower than natural hair, as a result, the hair having bending rigidity of the same level as the wearer's own hair growing on the scalp is attached to the wig base periphery or the total peripheral region. Therefore, when the wig is worn, and the hair attached to the periphery or the total peripheral region is put over the neighboring wearer's own hair and blended therewith, the wig hair and the wearer's own hair show similar behavior, mutually blend well, and are not easily separated. Therefore, wig wearing is not easily visible.
  • the hair style can be formed which has such bulky feeling that a wearer has so far never accomplished. If the hair attached to the wig base periphery or its total peripheral region has curl diameter or length of about the same level as the wearer's own hair, then the wearer's own hair tends to blend well with the wig hair, and wig wearing is furthermore not easily visible. In addition, the hair style can be easily formed in short time according to the wearer's preference only by simple adjustment.

  • the hair attached to the total peripheral region 31 A of the wig base 31 has bending rigidity lower than that of average natural hair, that is, bending rigidity of the same level as that of the wearer's own hair
  • the hair attached to the region 31 B of the top portion 31 e where the hair is not likely to be mixed with the wearer's own hair has high bending rigidity compared with the hair attached to the total peripheral region 31 A. Therefore, since the hair attached to the total peripheral region 31 A of the wig base 31 is easily blended well with the remaining hair growing on the wearer's scalp, and shows similar behavior to the wearer's own hair by the influence of such circumstances as humidity, it is not likely for wig wearing to be recognized.
  • the hair attached to the region 31 B of the top portion 31 e and to the adjustment region 31 C has higher bending rigidity than the wearer's remaining hair, bulky feeling can be easily attained, and various hair styles can be made in response to the wearer's needs.
  • Explanation is made of a twelfth embodiment of the pattern to attach hair to a wig base 31 . Its difference from the eleventh embodiment is that the hair attached to the region 31 B of the top portion 31 e of the wig base 31 and the hair uniformly mixed and attached to the adjustment region 31 C have low rigidities. It is the same case as in the eleventh embodiment that the hair is made of a polyamide fiber of a sheath/core structure. Artificial hair having bending rigidity 3.9 ⁇ 10 ⁇ 3 gf ⁇ cm 2 /strand is attached to the total peripheral region 31 A of the wig base 31 .
  • the twelfth embodiment differs from the eleventh embodiment in that bending rigidity of the hair attached to the region 31 B of the top portion 31 e is low compared with the eleventh embodiment, and the whole hair attached to the wig is so designed as to have lower bending rigidity than natural hair, so that it is suitable to the wearer having comparatively soft hair, that is, suitable to the user having hair of bending rigidity about 3.1 to 4.7 ⁇ 10 ⁇ 3 gf ⁇ cm 2 /strand.
  • Explanation is made of a thirteenth embodiment of the pattern to attach hair to a wig base 31 . Its difference from the eleventh embodiment is that, contrary to the twelfth embodiment, the hair attached to the region 31 B of the top portion 31 e of the wig base 31 and the hair attached to the adjustment region 31 C mixed therein have strengthened rigidities. It is the same case as in the eleventh embodiment that the hair is made of a polyamide fiber of a sheath/core structure. Artificial hair having bending rigidity 3.9 ⁇ 10 ⁇ 3 gf ⁇ cm 2 /strand is attached to the total peripheral region 31 A of the wig base 31 .
  • bending rigidity of the hair attached to the top portion 31 e is high compared with the eleventh embodiment to increase the difference from natural hair, bulky and rough feeling can be attained, thereby hair styles so far not realized, for example, with standing hair can be formed. Therefore, it is suitable to the wearers requiring hair styles of bulky feeling.
  • the wig of the thirteenth embodiment is assumed for the case wherein the wearer's own hair has bending rigidity about 3.4 to 4.4 ⁇ 10 ⁇ 3 gf ⁇ cm 2 /strand.
  • the hairs of different bending rigidities are attached to respective regions of a top wearing type wig, but as described before, like the fifth to the eighth embodiments for the front hiding type wig, the first artificial hair made of a polyamide fiber of a sheath/core structure and the second artificial hair made of a polyester fiber may be used as the hair attached to the wig base 31 . Also, the hairs of different curling diameters and/or lengths may be attached further to respective five regions in the cases of the eleventh to the thirteenth embodiments.
  • FIG. 21 is a table showing the properties of the hair attached to a wig base 31 in a fourteenth embodiment of attaching patterns.
  • the regional partition wherein the hair of the pre-determined bending rigidity is attached in the wig base 31 and the regional partition wherein the hair of the pre-determined curl diameter and/or length is attached are separately determined. Namely, in the main region 31 B as a top portion 31 e , the hair of the curl diameter 30 mm, the length 18 cm, and bending rigidity 6.5 ⁇ 10 ⁇ 3 gf ⁇ cm 2 /strand is attached.
  • the hair of the curl diameter 30 mm, the length 15 cm, and bending rigidity 3.9 ⁇ 10 ⁇ 3 gf ⁇ cm 2 /strand is attached.
  • the hair of the curl diameter 35 mm, the length 20 cm, and bending rigidity 3.9 ⁇ 10 ⁇ 3 gf ⁇ cm 2 /strand is attached.
  • the hair of the curl diameter 45 mm, the length 30 cm, and bending rigidity 3.9 ⁇ 10 ⁇ 3 gf ⁇ cm 2 /strand is attached.
  • the hair of the curl diameter 30 mm, the length 15 cm, and bending rigidity 3.9 ⁇ 10 ⁇ 3 gf ⁇ cm 2 /strand and the hair of the curl diameter 30 mm, the length 15 cm, and bending rigidity 6.5 ⁇ 10 ⁇ 3 gf ⁇ cm 2 /strand are mixed half to half in the mass ratio and attached.
  • the hair of the curl diameter 35 mm, the length 20 cm, and bending rigidity 3.9 ⁇ 10 ⁇ 3 gf ⁇ cm 2 /strand and the hair of the curl diameter 35 mm, the length 20 cm, and bending rigidity 6.5 ⁇ 10 ⁇ 3 gf ⁇ cm 2 /strand are mixed half to half in the mass ratio and attached.
