DETAILED DESCRIPTION OF THE INVENTION The present invention relates to toy dolls, and more particularly to doll hair and doll hair conditioning.
ng) method.

There are countless toy dolls developed over the years for children's use. The placement of toy dolls can be enhanced if children can use it to imitate adults, because children always want to do what adults appear to be doing. be. Other features of toy dolls that enhance location are that they are easy for children to use, durable, safe for children to use, and cheap.

Young girls especially enjoy imitating the act of arranging their hair. Dolls have been developed that include sets of interchangeable hairpieces, each having a different hairstyle, so that a child can change the doll's hairstyle. Other dolls have been developed that have long hair that can be curled and tied in place. In general, prior art dolls do not allow children to imitate highly complex hair styling techniques, such as straightening curly hair using hair conditioners.

It is therefore an object of the present invention to provide a new and improved doll hair.

It is an object of the present invention to provide a new and improved method of styling doll hair.

It is still another object of the present invention to provide a method for straightening the doll's curly hair 7 in a manner that allows the hair to be returned to the curly shape.

The above and other objects of the present invention are to provide a method for treating plastic camphor fibers to form curly hair on dolls which can lengthen the temporary curls and maintain the ability to return to the curly shape any number of times. include.

The plastic fibers are first wrapped around a cylindrical mandrel and curled by heating at about 135° C. for about 1 minute. The curled fibers are coated with a fiber treatment solution consisting of polyvinyl alcohol and a synthetic structure softener. The coated fibers are then heated to about 135° C. for about 3 hours.

The elevated temperature and the presence of structural softeners significantly strengthen the fibers and crosslink the polyvinyl alcohol with the fibers in a manner that improves their resistance to abrasion. The reinforced fibers are then attached to the doll's head to simulate curly hair.

The conditioner also provides the ability for children to temporarily straighten the doll's curly hair. Formula A is in the form of a non-toxic, non-flammable aqueous powder containing polyvinyl alcohol and a bacteriostatic agent.

To straighten the doll's hair, the child mixes the powder with water to create a conditioning solution that is sprayed onto the curly hair. Next, brush your hair to form a straight hairstyle. The conditioning solution acts as a stiffening agent and holds the hair fibers in a straightened shape.

Straightened hair can be returned to a curly shape by washing the hair with water to remove the conditioning solution. Upon drying, the fibers return to their original curly shape.

The straightening and recurling operations can be repeated many times without damaging the fibers.

Other objects, features and advantages of the invention will become apparent from reading the specification accompanied by the drawings.

Referring to FIG. 1, a block diagram of the steps used to generate doll hair in accordance with the present invention is shown. The starting material (step 10) is nylon or Saran (5ar
copolymer filament (fila) produced as
ment) and can contain vinyl chloride-vinylidene chloride. These fiber compositions are particularly suitable for use as doll hair because they are relatively flame-free.

The fibers are typically 80 mm long, contain 10 filaments and have a weight of about 600 denier. Typical Saran fibers used in the present invention are Asahi Dow Chemical Co., Ltd., Tokyo;
It is a type AD600-10 supplied in Japan.

The fibers described above are first wound around a cylindrical mandrel and then curled by heating for about 1 minute at a temperature of about 135° C. (step 20). In a preferred method, the diameter of the mandrel is selected such that the curls produced have a diameter of about 7 mm.

A fiber treatment solution is prepared by mixing together (such as in a stainless steel tank) polyvinyl alcohol, synthetic fabric softener, and softened water (step 30). Structural softeners belong to the type containing crosslinking agents such as aldehydes, crosslinking catalysts in salt form and surfactants such as polyethoxy esters or polyethylene glycol monolaurates. Typical compositions of fiber treatment solutions used in the present invention are listed in Table 1.

Arrange the amount of fibers evenly in the net bag (Step 4)
0) Prepare for immersion into the processing solution by: It has a diameter of about 8t-rn and a length of about 1.5m,
A bag with evenly spaced holes (approximately 1001 [1 hole 7 inches) on its surface has a curly 400~
4501. Tightening means, such as rubber bands, can be placed in the bag at regular intervals along its length to prevent the fibers from bunching together. The bag containing the fibers is completely immersed in the treatment solution (stage 1if50).

Depending on the amount of treatment solution prepared, a number of such bags can be immersed simultaneously.

It has been found that a ratio of 1 bag of fibrous 450f to 1 gallon of treatment solution can be used.

Stir the fibers of the bag into the treatment solution for about 2 hours while maintaining the temperature of the solution in the range of about 10-20°C (step 60).
. During this time, the fibers become coated with the solution. The presence of surfactant in the solution ensures that it flows through the fibers for even coverage. Additionally, surfactants prevent adjacent fibers from sticking together. The bag is then removed from the solution and any excess solution is removed, for example by spin-drying the bag at a gentle speed (step 7).
0).

The dried bag fibers are then heated (eg, in an oven) to a temperature in the range of about 123-136° C. for about 3 hours (step 80), and then allowed to cool to room temperature (step 90). Heating crosslinks the polyvinyl alcohol with the fibers, strengthening them without significantly disturbing the curled shape.

The curled fibers are then removed from the casing and applied to the doll's plastic head in a manner known to those skilled in the art to simulate curly hair (men's floor 100). Specifically, commercially available threading machines can be used to thread the fibers through the heads of plastisol dolls. The completed head can be placed on a doll's body to form an attractive doll with curly hair.

The fiber treatment methods described above are used to strengthen the hair fibers so that they do not become frayed or torn during subsequent straightening or recurling of the fibers in the manner described below. The use of a wetting agent such as polyethylene glycol monolaurate or a surfactant such as polyethoxy ester as a component of the fiber treatment solution of the present invention acts to prevent adjacent fibers from bonding together and thus strengthen the fibers. retains curly hair-like outer ml.

Treated doll hair can be straightened in the following way. Dry rice-shaped moisturizing powder that children can easily use to grow doll hair is water-soluble and contains polyvinyl alcohol. Bacteriostatic agents are also added to inhibit the growth of bacteria. Table 2 lists typical compositions of the humidity control powder used in the present invention.

Moisture Conditioning Powder Table 2 With reference to FIG. 2, the moisture conditioning powder is prepared for use by mixing with water to produce a two-layer solution of the powder (step 110). The resulting solution is sprayed onto the doll's curly hair until substantially all of the fibers are wetted (step 120).
).

While the hair dries, brush the curls until straight (step 130). The polyvinyl alcohol forms a somewhat sticky coating on the fibers and dries quickly to hold the fibers in a straight position (step 140). As a result, children can use the hair conditioner to condition their hair in a way that mimics the conditioning operations used by adults.

The moisture conditioning powder is formulated to be non-toxic and flame retardant for use by young children. Humidity conditioning solutions are also easy to prepare, requiring only mixing with water. To aid in mixing, a marked bottle can be provided to indicate the relative proportions of water added with the powder. The bottle can be fitted with a spray tip suitable for applying the solution to curly hair.

In order to restore the straightened doll hair to its original curly shape, the straightened hair is washed with water to remove the moisture conditioning aqueous solution from the fibers (Step 1si150). As the fiber dries, it regains its original curly shape. This feature of the invention further increases the practicality of hair styling for children.

The treatment solution increases the strength of the fibers, which can be repeatedly straightened and recurled without losing the ability to tear, reduce or recurl.

Tests conducted on reinforced fibers show that they can be straightened and recurled 100 times successfully. On the other hand, fibers not treated according to the invention tear after being straightened and recurled only seven times and lose their ability to recurl.

While disclosing the invention and describing certain embodiments in detail,
The invention is not simply limited to this specific example. Many changes will occur to those skilled in the art that are within the spirit and scope of the invention. Accordingly, it is intended that the invention be limited in scope only by the scope of the claims that follow.
