Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hat formed by cutting and sewing a knitted silk or woven fabric.
The present invention relates to a method for manufacturing hats.

Conventionally, knitted hats are knitted only from yarns made of natural fibers and/or synthetic fibers, so the entire hat is soft and has no waist, making it extremely difficult to maintain a desired hat shape. Ta.

In order to overcome these drawbacks of knit hats, raw yarns (e.g. cotton yarns) made of natural fibers and/or synthetic fibers are used.
There are knitted hats that are knitted with reinforcing yarns made of polyvinyl chloride and polyvinyl chloride, thereby making use of the strength effect of the reinforcing yarns to knit hats with a waist.

In this case, compared to the former knit hat, it is possible to provide a hat that has a shape-retaining effect with a relatively firm shape due to the reinforcing yarn, but in the hat (11) after molding, as shown in @8 (a) Since the raw yarn full and the reinforcing yarn θ2) are separated, not only the reinforcing yarn (I21) is exposed from the front and back of the hat, but also the reinforcing yarn is shiny, so the shiny state is visible, and this is the same as the seed. This was a fatal flaw in the appearance of hats.

In order to solve this problem, a method of knitting so that only the shiny reinforcing yarn is on the back side has been considered. However, with this knitting method, a problem arose in that the number of knitted fabrics was limited.

Furthermore, in the case of mesh or lace silk fabrics used in the summer, even if reinforcing threads are knitted on the back side, the reinforcing threads (12) will form a bridge in the mesh space (8) as shown in Figure 8 (b). This resulted in the appearance of this type of knitted hat (11) being extremely unsightly.

For knitted hats, when the pattern is transferred,
Inevitably, the reinforcing threads were exposed on the front side, and the result was an extremely unstable silk fabric, detracting from the original aesthetic appearance of the knitted hat.

Like Son, if you roughly divide the conventional methods, there are two types: knitting using only raw yarn and knitting using both raw yarn and reinforcing yarn. The lack of a waist makes it difficult to maintain the shape of the hat, and in the latter case, the silk fabric is restricted, and the reinforcing threads are exposed to the outside. It had the fatal flaw of impairing the

In any case, with the conventional methods, it has not been possible to obtain a method for manufacturing a hat that stably maintains the hat shape and is free from restrictions on the knitted fabric.

In order to solve these conventional problems, the great invention is able to obtain free knitting patterns without restrictions on silk fabrics, and to maintain the desired shape of the hat after manufacturing, and in particular improves the appearance of knitted hats. The object of the present invention is to provide a completely new and useful method of manufacturing a hat without compromising the quality of the hat in any way.

In other words, it is knitted with a raw yarn made of natural fibers and/or synthetic fibers and a special thread that melts at a lower temperature than the raw yarn, and is sewn with a woven silk fabric or a woven fabric. Preliminarily forming a hat with a desired shape, and then fitting the end of the hat into a mold and heating it with steam to melt the special yarn in the raw yarn, and then reheating at a higher temperature than the heating temperature. The hat is manufactured by fusing and integrating the special yarn with the raw yarn, then fixing the general shape of the hat by air drying or cooling, and removing the mold.

Embodiments of the present invention will be described below according to an example shown in the drawings.

First, natural fibers such as cotton yarn (1) and B yarn +
At the same time, a hat body (3) of a desired shape is knitted in advance by knitting with a heat-fusible special yarn (2) made of low-temperature melting polyester from No. 11.

At this time, the amount of the special yarn (2) relative to the raw yarn (1) is adjusted depending on the softness and hardness of the cap (4). In other words, in order to obtain a relatively hard hat (4), a large amount of special yarn (2) is required for the raw yarn ill.

Moreover, in this case, it is of course possible to dye the original yarn and the special yarn separately or simultaneously.

The cap (3), which is knitted in a predetermined shape using arbitrary raw yarn fil and special yarn (2), has a very unstable shape as shown in FIG. Next, this hat (3)
) is heated with steam in the next step.

As a heating means, the cap main body (3) is placed on a metal cap mold (6) as shown in FIG. 2, and then placed in a steam chamber and heated (to a temperature of, for example, 95° C.).

By the above method, when the hat (3) is heated with steam, the raw yarn (1) and the special yarn (21) that are woven together are heated by steam, and the special yarn (21) that melts at a lower temperature than the raw yarn (li) is heated. is in a molten state, and as shown in Fig. 3, the special thread (2) melts and melts into the original thread (11) and becomes integrated.Especially because it is heated with steam, the melting becomes very good.

Next, take out the cap mold (61) from the steam chamber, put the cap mold (61) into the next drying chamber, and reheat it at a higher temperature (for example, 130 °C) than the steam heating temperature (100 °C or less). do.

When reheated in this way, the raw yarn (11) and the special yarn (2) that make up the hat body (3) that is fitted onto the hat mold (6) are further heated to a high temperature, so that they are fused in a good state. At the same time, they are forced to dry and the integration of the two increases.

Next, the hat body (3) that has been steam-heated and reheated by the above method is taken out from the drying room together with the hat mold (6), and then cooled or naturally dried, and after a predetermined period of time,
When the cap is removed from the cap mold (6), the desired shape of the cap (4) as shown in FIG. 4 can be fixed and finished.

Therefore, in this state, the hat (4) has a very stiff shape, as if it had been glued on.

When the cap (4) manufactured in this manner is put into the hat (4), the raw yarn ill is transformed into a special yarn ( 2) is in a welded and integrated state, so the special thread (
Since the gloss of 2) is hardly exposed to the outside, it often impairs the appearance of a knitted hat.

Furthermore, even when manufactured as a lace or mesh knit hat (4)l for summer use as shown in Fig. 5, the reinforcing yarn α2) does not become cross-linked in the mesh space (8) as in the past. As a result, the appearance form of the hat (4) is maintained without any loss of aesthetic appearance.

In particular, since the special thread (2) is integrally melted into the raw thread (1) after the production of the hat (4), when the hat body (3) is formed, the reinforcing thread 02 is attached to the back side like the conventional one. Since there is no spring pattern to knit so that the front side and back side are exposed, there are no restrictions on the knitted fabric, and the knitting pattern (sawn structure 3) can be freely knitted, making the knitting work extremely simple. The workability is particularly good.

In addition, in the above example, the raw yarn (ll) and the special yarn (2)
However, as shown in Figure 6, it is also possible to twist the original yarn and the special yarn (2) in advance into a single thread and knit it. When knitted, the effect of integrating the two by heating becomes even better.

In the above embodiment, the hat body (3) is directly knitted with the raw yarn 111 and the special yarn (2), but as shown in FIG. 9(a), the raw yarn (1) and the special yarn ( 2) or a woven fabric (9)' that is woven from raw yarn (1) and special yarn (2), into the shape of the hat body (3) as shown in Figure 7 (B). It is also possible to cut the hat into 6 pieces (lO) and sew them to form the desired hat body (3) in advance as shown in FIG. that time,
Preheating at the stage of knitted fabric (9) or woven fabric (9)l,
It is also possible to then cut and sew the hat to form the main body of the hat, and then heat it again.

Further, in the above embodiments, the entire hat body is formed or sewn, but it is of course possible to form only the head part or the edge of the hat by the above method using both threads. Further, the hat body is not limited to knitting, and may be woven.

Furthermore, as the raw yarn fil, it is preferable to use cotton yarn with excellent adsorption effect as shown in the above embodiments. It may be a composite material made by combining fibers or a single synthetic fiber material.

Further, the special thread (2) is not limited to polyester, but may be nylon, acetate, polypropylene, etc. as long as it has a heat-melting property that melts at a lower temperature than the original thread.

Also, even if it is a commercially available heat-adhesive fiber thread, the special thread is one that melts at a lower temperature than the original thread, and is a heat-meltable thread that can be melted and integrated with the original thread by heating. Further, cooling is necessary from the viewpoint of workability during mass production, but as long as the working time is not a concern, natural drying may be used, and the cooling method is also available. In addition, the above-mentioned integration of the raw yarn and special yarn is not only when the special yarn is completely absorbed and melted into the raw yarn, but also when a part of the yarn remains as a coating on the outer periphery of the raw yarn. The shape of the mold for the hat and the means for attaching the mold to the hat body are made up of two layers.

Other design changes may be made within the scope of the present invention.

As shown above, the present invention involves preforming a cap body in a desired shape by knitting, straddle weaving, or serpentine sewing using a raw yarn and a special thread that is heated and melted at a lower temperature than the raw yarn. The hat is generally heated with steam, then reheated at a higher temperature than the previous steam heating, and then cooled or air-dried to fix and finish the hat, so the special thread is thermally fused to the raw thread during the steam heating. In addition to the unifying Z, the reheating further increases the fusion of the special yarn into the raw yarn and forced drying, so compared to the conventional method, the special yarn often melts and separates and remains. As a result, the special thread will not be able to shine or cross-link into the space of the lace or mesh, which will deteriorate the appearance and shape of the hat, especially a knitted hat. A special effect was obtained that did not cause any damage.

Furthermore, by steam heating and subsequent shape forming after reheating, and cooling or natural drying, the F-form of the manufactured hat is much better than that of the conventional one, as is the integration of the raw yarn and the special yarn and t0. Since it is fixed in a fixed state, the shape retention effect has become especially remarkable.

Another important point is that by integrating the special yarn and the raw yarn, it is possible to knit or weave regardless of the front or back side, compared to the conventional method of separating them. - Cutting knitting and 1D weaving work μ has become extremely simple, and has succeeded in shortening the working time and significantly reducing the working cost.

In particular, there are no restrictions on knitted patterns (silk braided fibers).1. Since q, it is possible to obtain a free knitting pattern f ≠ ( ＾, etc.)
It came to fruition. Furthermore, the main body of the hat can also be formed by cutting and sewing the raw material or kneaded material formed by the raw thread and special thread. It became nf Noh.

1101. Since the working process of all wood is simple, it is suitable for mass production and has great practical effects such as greatly reducing the unit price of hats.
