Description

[Detailed description of the invention] The present invention relates to a method for producing flocked fabric for a wig.

More specifically, the present invention relates to a method for manufacturing a flocked wig using a mesh fabric.

Flocked fabric for wigs with mesh fabric was published in 1977-1.
i', is described in Publication No. 506, and here, it is knitted with a synthetic yarn in which a non-stretchable thread is spirally wound around a stretchable thread, and one piece of fc net fabric is placed on a piece-shaped foot last. Fix it there and apply epoxy resin-polyurethane pattern fat mixture color 1
A hemispherical net fabric curved in the shape of a head is used, which is obtained by coating and curing a curable synthetic resin such as the following.

However, when using a net fabric constructed in this way, the following problems are observed. (2) Since the knitted fabric is mainly composed of elastic yarns, it is necessary to mold the fabric into a certain shape using synthetic resin. (3) Even if it can be formed into a certain shape, the knitted fabric has no elasticity, so it is difficult to maintain that shape, especially the fine uneven shape. (4) For this reason, it is difficult to The fabric can only be used for a part of the wig base, and the main purpose of using the fabric, which is breathability and moisture permeability, cannot be sufficiently improved. (5) The entire wig formed from it cannot have sufficient strength. Rather than a scale that easily loses its shape, the scale of the present invention easily causes misalignment in the mesh part of the mesh.
As a result of studying flocked fabrics for wigs that can provide wigs with excellent texture and wash resistance, we have found that they are not a measure that fully achieves the purpose of improving moisture permeability for wigs. It has been found that the above object can be effectively achieved by using a net fabric knitted from neutral yarns and fixing it with synthetic resin or rubber.

Therefore, the present invention relates to a method for manufacturing a flocked fabric for a wig, and the flocked fabric for a wig uses a fabric knitted from yarns that are essentially not elastically stretchable, and the fabric is coated with a synthetic resin or rubber solution. Alternatively, it can be manufactured by applying a suspension, pressing and fixing it onto a head-shaped male die without wrinkles, and then curing the synthetic resin or rubber.

Examples of net fabrics knitted from essentially non-elastic and stretchable yarns include polyester, polyamide, acrylic, rayon, polyvinyl alcohol, Japanese, etc. A fabric knitted with multifilaments of fibers or blended fibers thereof is used, and the mesh is preferably a so-called lace knitted fabric having a polygonal shape such as a square or hexagon.

A solution or suspension of synthetic resin or rubber is attached to these silk fabrics, but as synthetic resin or rubber,
Acrylic acid ester resin, ethylene-vinyl acetate copolymer resin, vinylidene chloride-vinyl acetate copolymer resin, vinyl chloride resin, urethane resin, epoxy resin, SBR, NB
R, etc. are used, and depending on their type, they are used in the form of a solution such as a single solvent solution or a suspension such as latex.

Adhesion of synthetic resin or rubber to the mesh fabric is generally done by coating, dipping, spraying, etc. After the synthetic resin or rubber is thoroughly blended into the fibers, the synthetic resin or rubber is applied so as not to block the mesh.
Any excess solution or suspension adhering thereto is removed by means such as centrifugation.

In this way, the net fabric to which synthetic resin or rubber is attached in the form of a solution or suspension is placed over a head-shaped male mold, and the lower part is secured with a rubber band to prevent wrinkles. After fixing the solution, the organic bath agent in the solution and the water in the suspension are dried and removed.

Then, the synthetic resin or rubber is heated to a temperature appropriate to the type of rubber to cure it.

In this way, the flocked fabric for a wig, which is made of a net fabric shaped into the shape of a head, can be used for flocking in various ways.

The most basic and characteristic way of using it is to apply a coating consisting of a synthetic resin solution represented by an organic solvent solution of urethane prepolymer to the whole or a part of the edge, about 3
Apply with a width of ~lOhm, and further increase the application area to approximately 5~3 Ohm.
It extends to the outer periphery with a width of 0.111 mm to form a film-like edge that does not include the mesh fabric, and if necessary, a coating material is also applied to the divided portions of the silk fabric.

Since the flocked fabric of this type is entirely made of net fabric except for the edges, it promotes good air permeability and moisture permeability, while also improving head shape retention and texture. It is possible to provide a wig that is excellent in these respects. In addition, this wig can be made to have a suitable hardness overall, so combined with the synthetic resin coating on the edges, you won't feel any discomfort when putting it on and taking it off. . Furthermore, it is not only possible to mold a shape that faithfully copies even the smallest details of the head shape, but it also maintains the molded shape even though it is a mesh type that is inferior in shape retention. Since the quality is good, the feeling of wearing the wig will not be impaired for a long period of time.

If it is required to increase the flocking strength of the flocked fabric, leave the part corresponding to the top of the head (circular or oval part with a diameter of about 5 to 10 mm) and apply the paint to the other mesh parts. You can also do it. In this case as well, the entire or part of the easily conspicuous edge is provided with an extended coating that does not have a mesh,
It is desirable to create a natural feel.Alternatively, instead of using this mode of use, cut out only the mesh portion corresponding to the top of the head, attach it to the male mold of the head shape, and cut out the edge (approximately 3
It is also possible to apply a coating agent to the width of about 10i + i) and other parts corresponding to the outer periphery, and use it as a flocked fabric made mostly of synthetic resin coating.Furthermore, in the above usage mode, In order to protect the knots of the hair that has been flocked to the fabric, maintain breathability, and improve the feel of the fabric against the fabric, it is recommended that two layers be layered from the beginning when using the fabric as a backing agent. It is desirable to use a mesh fabric that has been

Alternatively, it is also possible to use mesh fabrics that have been separately hardened with synthetic resin or rubber, but in any case, the two fabrics can be bonded using any suitable method such as paint, adhesive, ultrasonic welding, sewing, etc. shall be fixed to each other by means of The type of netting used may be the same material for the upper and -F two sheets, but the upper netting is used for flocking, so strength is important, and the lower netting is required to be in contact with the scalp. Since this is a part that will be worn, sufficient consideration must be given to the texture.

Next, the present invention will be explained with reference to examples.

Example 1 Degreasing by immersing in methyl ethyl ketone at room temperature,
A washed and dried nylon tulle lace net with a polygonal mesh is immersed in a water-soluble emulsion of self-crosslinking resin (Chuo Rika Products Rikabond 66), and after the emulsion is fully absorbed into the fibers, the mesh is removed. Remove excess emulsion adhering to the fibers by centrifugation to avoid clogging.

After covering the net fabric to which the emulsion has been applied in this way over the male head-shaped mold and fixing it without wrinkles,
Water in the emulsion is dried and removed.Then, the emulsion is heated to the crosslinking temperature of the resin to cause a crosslinking reaction.

Approximately 511 mm is applied to the entire edge of the fabric thus formed.
The flocked fabric for a wig obtained by applying a urethane prepolymer solution with a width of M and further extending the applied area to a width of about 20 fins on the outer periphery to form a logging area has a shape of the head. It retains its properties well, yet its texture remains intact.

Example 2 In Example 1, a polyester lace having a rectangular mesh was used as the nylon tulle lace, and an aqueous SBH latex was used as the resin component for dipping.

The resulting net-like flocked wig fabric maintained its head shape well and had a hard feel.
