Modified regenerated collagen fibers which have improved water resistance and heat resistance problematic in regenerated collagen fibers, impart heat shape memory ability, are excellent in stretchability (tenacity) and the feel of the surfaces, and have no coloring. The modified regenerated collagen fibers contain a component (A), which is vinylbenzoic acid or a salt thereof, or a polymerized product containing the component (A) as a constituent monomer in the regenerated collagen fibers.

Provided is a wig including a planting net divided into a plurality of planting nets, the planting net including a front planting net, one pair of side planting nets, and a rear planting net. The front planting net is manufactured as a wig fabric by knotting wig fibers, a loop pattern with a certain shape prepared in advance is provided as a plurality of portions on the one pair of side planting nets and the rear planting net, and an ornamental hairpiece in a certain shape is connected to the loop pattern, and the front planting net, the one pair of side planting nets, and the rear planting net are sewn together so that a user is able to create a more natural look when wearing the wig.

Example methods of installing replacement hair includes installing a fitted scalp mesh over natural hair of a subject experiencing hair loss or hair thinning and pulling from about 80% to 100% of the natural hair beneath the fitted scalp mesh through the fitted scalp mesh as a plurality of natural hair groupings. The method can also include forming a plurality of hair tracks oriented transverse relative to the lateral spacing with multiple natural hair groupings having different starting locations along the individual hair tracks. Individual natural hair groupings of the individual hair track can pass through and are secured by at least two hair fasteners along the individual hair track. Additionally, the method can include installing at least one hair weft on the fitted scalp mesh.

A method for producing wig. The method includes: preparing a first wig component obtained through a machine hair implantation process; dividing an elastic wig cap into different regions; stitching and securing the first wig component to the first region of the elastic wig cap; hand-tied a second wig component on the second region of the elastic wig cap; trimming a transitional area between the first region and the second region to generate a wig, etc.

The present invention belongs to the technical field of wig production and specifically relates to a manufacturing method for layered hairpiece product. The manufacturing method for preparing layered hairpiece product comprises the following steps: step I. preparing a raw hairpiece; step II. cutting a manufacturing unit: cutting one or more manufacturing units having a trapezoidal shape from the raw hairpiece; and step III. homogeneously mixing each manufacturing unit. In the present invention, after cutting the layered part having a trapezoidal shape and mixing the same homogeneously, the layered part of the layered hairpiece product resembles a natural look at the hair ends with high similarity to real hairs.

A hair planting apparatus includes a mounting portion for mounting a base material, and including a work opening for planting, a hair planting unit for binding hair for planting to the material in the work opening, a transport mechanism for positioning the hair planting unit relative to each mesh hole of the material mounted on the mounting portion, an imaging unit for capturing images of a plurality of mesh holes of the material mounted on the mounting portion, a tilt detection unit for obtaining, from the image captured by the imaging unit, an alignment direction of the mesh holes of the material, and a correction mechanism for correcting the orientation of the material on the mounting portion according to a tilt angle of the alignment direction of the mesh holes of the material with respect to a predetermined direction.

A wig maintenance device includes a water resistant, elongated hood having a concave inner surface, a convex outer surface, and a fold formed along at least one edge thereof, a pocket formed on the convex outer surface at a first end of the water resistant, elongated hood; a flexible reinforcement strip contained within the fold; and an absorbent installed within the pocket for mess-free maintenance of hair pieces. The device allows a user to keep their workspace clean and dry.

A hair planting apparatus includes a mounting portion for mounting a base material where planting is performed, and including a work opening for planting, a hair planting unit for binding hair for planting to the base material in the work opening of the mounting portion, and a feed device disposed around the mounting portion and feeding the base material with a roller contacting the base material from below. In the hair planting apparatus, the feed device feeds the base material in at least two intersecting directions.

A method for hair-braiding that includes making a lace closure is described. The one-stranded method includes making a lace closure with synthetic hair, parting locks of the synthetic hair from the lace closure into sections of hairs, pulling a loop of a crochet over a hook, attaching the sections of hairs to the hook, pulling the hook with the attached sections of hairs through the loop of the crochet, wrapping the sections of hairs around the crochet, tying a portion of the sections of hairs around the crochet, and applying heat to the wrapped sections of hairs to heat shrink the sections of hairs.

A hair planting apparatus includes a base support mechanism that supports a base material, a hair holding mechanism that holds hair for planting on one side of the base material, and a hair planting part that knots the held hair for planting to the base material by hook needles. The hair holding mechanism includes a first gripping mechanism and a second gripping mechanism that individually grip the hair for planting, and the first gripping mechanism includes two sliding plates that slidably grip the hair for planting, an elastic body that applies gripping pressure to the two sliding plates, and a release mechanism that opens the two sliding plates to release the hair for planting.
