The present invention provides artificial hair, an artificial hair unit, a method of applying artificial hair, and a method of applying an artificial hair unit, in which a fiber bundle does not hang down under its own weight, rises up, and exhibits excellent appearance with extra volume at a root. Also provided is a configuration including a base material, a plurality of fiber bundles, and a fixing thread. In the configuration, the base material may have a first side extending in a first direction. Each of the plurality of fiber bundles includes a plurality of fiber parts and a connecting part, where the connecting part connects a first end side of each of the plurality of fiber parts and extends in a direction different from an extending direction of the plurality of fiber parts, and where the fixing thread attaches a vicinity of the connecting part to the base material.

The present invention provides a fiber for artificial hair and a hair decorating product having superior combing property. A fiber for artificial hair includes vinyl chloride based resin, vinyl based copolymer, and vinyl chloride based acrylic graft copolymer.

Hair extension drying device includes an enclosure comprising a base and an upwardly extending wall surrounding the base. The wall is configured for receiving a top cover of the enclosure. A fan is coupled to the top cover with the fan being configured for circulating air within the enclosure. A heating unit is coupled to the base. A hair extension holder spaced apart from the heating unit by one or more vertical supports. The hair extension holder includes at least one laterally extending plate that includes perforations or fluid pathways.

An acrylic fiber for artificial hair includes an acrylic copolymer obtained by copolymerizing acrylonitrile, vinyl chloride and/or vinylidene chloride, and a sulfonic acid group-containing vinyl monomer; and an organic solvent that can dissolve the acrylic copolymer, where the organic solvent is present in an amount of 0.1 to 3% by mass with respect to the total mass of the acrylic fiber for artificial hair. The acrylic fiber for artificial hair has an average surface roughness of 5900 μm.sup.2 or less in an area of 40 μm long and 80 μm wide of the side surface of the fiber.

A removal and re-application board for hair extensions and process of using same. The board contains at least 3 serially spaced apart lines (linear or curvilinear), vertically or radially spaced apart. Hair extension bands are mounted on, above or below the lines. Board indicia conveys sequential band removal and board placement, and then band board-dismount and re-application sequential order data to re-apply the hair bands on a user's head. When the bands are on-board, the bands from a columnar matrix; therefore the serially spaced apart lines provide board-mounting and board dismounting data to the stylist (board-mounting is hair band removal; board dismounting is band re-application). The indicia and the serially spaced apart lines allow for hair bands to be easily stored (board-mounted) and organized, such that the hair bands can be reliably re-applied to substantially the same location on a user's head.

Provided is artificial hair including chemical fibers and a fiber treatment composition that is adhered to the surfaces of the chemical fibers. The fiber treatment composition may include an oxazoline group-containing acrylic resin and an organic-modified silicone oil. The oxazoline group-containing acrylic resin may have a main chain that includes a (meth)acrylic acid ester and styrene.

A hair accessory includes bundled synthetic braiding hair. The bundled synthetic braiding hair can include a first bundle of synthetic hair and a second bundle of synthetic hair strands. Other bundles with different lengths can be included as well. The first bundle and the second bundle can have different lengths and can be bundled at a common center, or alternatively can have a common length and can be bundled with their centers offset by a predefined distance. A binder can be coupled about a waist of the bundled synthetic braiding hair. When the bundled synthetic braiding hair is folded about the binder, the different strand lengths work to define a substantially cardioid shaped perimeter of the bundled synthetic braiding hair.

A hair extension packaging apparatus is disclosed and configured for supporting a plurality of hair extensions thereon. In at least one embodiment, the apparatus provides a substantially planar upper portion, a substantially planar lower portion spaced apart from the upper portion, and a transition portion interconnecting the upper and lower portions such that the upper and lower portions are linearly offset from one another. A front surface of the upper portion provides a plurality of mounting mechanisms positioned and configured for removably securing the hair extensions thereto. The transition portion provides at least one substantially planar aperture surface on which there is positioned at least one extension aperture configured for allowing a free length of at least one of the hair extensions to extend therethrough, such that the free length of said at least one hair extension is positioned substantially adjacent to a rear surface of the lower portion.

One or more embodiments of the present invention relate to a core-sheath conjugate fiber for artificial hair including a core and a sheath. The core is composed of a polyester-based resin composition containing a polyester-based resin as a main component, and the sheath is composed of a polyamide-based resin composition containing a polyamide-based resin as a main component. A core-to-sheath area ratio of the core to the sheath is 2:8 to 7:3, and both a fiber cross-section and a core cross-section have a flat shape, a major axis of the core cross-section is in a direction that substantially coincides with a direction of a major axis of the fiber cross-section, and an eccentricity ratio of the fiber in a minor axis direction is 5% or more. As a result, fibers for artificial hair having a texture and an appearance that are similar to those of human hair and having favorable curl setting properties are provided.

One or more embodiments of the present invention relate to a core-sheath conjugate fiber for artificial hair that includes a core and a sheath. The core is composed of a polyester-based resin composition containing a polyester-based resin as a main component, and the sheath is composed of a polyamide-based resin composition containing a polyamide-based resin as a main component. The polyester-based resin composition and the polyamide-based resin composition contain a bromine-based flame retardant. In the core-sheath conjugate fiber for artificial hair, a core-to-sheath area ratio of the core to the sheath is 2:8 to 8:2. A fiber cross-section of the core-sheath conjugate fiber for artificial hair has a flat multilobed shape, and the fiber cross-section includes a hollow portion. A ratio of an area of the hollow portion to a total area of the fiber cross-section is 5% or more and 30% or less. The hollow portion has a polygonal shape. As a result, fibers for artificial hair that have a texture similar to that of human hair, high durability, favorable curl setting properties, and high flame resistance are provided.
