This application claims priority to Chinese Application No. 201611245345.9, filed Dec. 29, 2016, the contents of which are hereby incorporated by reference.
The present invention relates to caps, and in particular to a method for manufacturing an integrally formed cap and a cap manufactured by the method.
It is known that, most of conventional caps are produced by adopting a method in which a fabric is cut into multiple splicing pieces and then the splicing pieces are sewed together into a cap with a needle and threads. Such a method for producing caps has a lot of steps is complex in process and low in production efficiency. Moreover, in the process of cutting the fabric, a lot of rags will be produced, thus leading to waste of production material and high production cost. Furthermore, the quality of caps produced by the above-mentioned method is unstable and often fluctuates.
Integrally formed caps have also appeared in the market. Generally, these caps can only be produced by adopting knitted fabrics or leathers rather than woven fabrics. Knitted caps which are produced by knitted fabrics are not suitable for printing and laser cutting due to the sparse knitted structure of the knitted fabrics and the material characteristics of knitting yarns, while leather caps which are produced by leathers are generally not suitable for dyeing and finishing or laser cutting because of costs or rough edges. As a result, the production costs of conventional shaped caps are high, and appearances are monotonous and dull, thus failing to satisfy individualized demands of different users.
In addition, the main reason why the conventional integrally formed caps seldom use woven fabrics is that creases, raveled yarns or broken yarns are likely to occur after a flat fabric is pressed into a three-dimensional cloth cap. As a result, if patterns are processed on the fabric by printing, embroidery or laser cutting, they may be subjected to deformation, breakage, etc.
For solving the above-mentioned problems, the objective of the present invention is set to provide a manufacturing method characterized in simplified steps and reduced production costs. Moreover, according to the invention, caps can be produced with various patterns, and can be better matched in shape with the head of a user.
The technical solution adopted by the invention to solve the technical problems is described as follows.
A method for manufacturing an integrally formed cap comprises the following steps:
Step 1, preparing a fabric A and providing a shaping mold: providing a shell fabric B and a thermoplastic lining fabric C, superposing the shell fabric B on a surface of the lining fabric C and tightly attaching the shell fabric B to the lining fabric C, to obtain the fabric A needed, and providing the shaping mold which matches the shape of a cap;
Step 2, cutting: cutting the fabric A obtained in Step 1 into set dimensions;
Step 3, thermally shaping: tightly attaching the fabric A cut in Step 2 onto the shaping mold obtained in Step 1, thermally shaping the fabric A by a container, so as to integrally shape the fabric A into the cap, thereby obtaining a product needed.
As an improvement to the above-mentioned technical solution, the shell fabric B in Step 1 comprises one or two or more layers of fabric, and the lining fabric C is a woven piece woven from stabilized yarns or from stabilized yarns and yarns.
As an improvement to the above-mentioned technical solution, the lining fabric C is chemical fiber lining, cotton lining, or wool lining or combinations thereof.
As an improvement to the above-mentioned technical solution, in step 1 before the shell fabric B and the lining fabric C are appressed together to form the fabric A, the shell fabric B is subjected to one or more of printing, embroidery, laser cutting and dyeing and finishing.
Further, in step 1 the shell fabric B and the lining fabric C are bonded or sewed together.
Further, in step 1 the shell fabric B and the lining fabric C are bonded together by adhesive, and the adhesive is one or more of environment-friendly resin, TPU and hot melt adhesive.
Yet further, the method comprises a step of shaping the cap after the fabric A is thermally shaped into the cap in Step 3.
A cap comprises a cap body, which comprises a decorative layer located in the outer and a supporting layer located inside the decorative layer
The present invention has the following advantages: the shell fabric B and the thermoplastic lining fabric C are appressed together to form the fabric A, the fabric A is then appressed on the outer surface of the shaping mold, and finally the fabric A is thermally shaped into an integrally formed cap; therefore not only is the cap production speed greatly increased and the stability of cap quality effectively guaranteed, but also the fabric does not need to be cut into multiple splicing pieces, thereby greatly reducing the rags and saving the fabrics, thus the production process of the present invention not only results in a reduced production cost, but also is energy-saving and environment-friendly.
Moreover, according to the invention, before being produced into the fabric A, the shell fabric B is a piece of flat fabric. Thus, printing, embroidery, laser cutting or dyeing and finishing can be performed on the shell fabric B for producing various patterns or textures or three-dimensional patterns on the surface of the shell fabric B, for diverse appearances, satisfying individualized demands of different users.
In addition, according to the present invention the fabric A is attached tightly to and cover the outer surface of the shaping mold and then shaped integrally into the cap by thermoplastic shaping, thus the conventional method, in which pressing or squeezing a fabric when producing a cap by integral forming is required, is abandoned, and whereby creases, raveled yarns or broken yarns caused by pressing or squeezing are prevented from occurring on fabrics.
In cap production with the method of the invention, as long as the mold matched the head of a user in shape is provided, the cap matched with the head of the user in shape can be formed thermally, so that the cap produced with the method of the present invention can be better adapted to the head of the user in shape.
The present invention is further described in detail below in reference to the drawings and specific embodiments.

According to the invention, the shell fabric B 20 and the thermoplastic lining fabric C 30 are appressed together to form the fabric A 10, which is then appressed on the outer surface of the shaping mold for thermoplastically shaping, whereby a cap with a shape matched with the shaping mold is formed from the fabric A 10, and thus the objective of producing an integrally formed cap is achieved. Therefore, for cap production, production speed is greatly increased and quality stability is effectively guaranteed. Furthermore, as the fabric no longer needs to be cut into multiple splicing pieces, thereby resulting in greatly reduced rags, fabrics are saved. Resulting from above, the production process according to the present invention is characterized in reduced production costs, energy-saving and environment-friendly.
Moreover, before being produced into the fabric A 10, the shell fabric B 20 in the present invention is a piece of flat fabric, thus printing, embroidery, laser cutting or dyeing and finishing can be easily carried out on the shell fabric B 20 to produce various patterns or textures or three-dimensional patterns on the surface of the shell fabric B 20, for divers appearances, to satisfy individualized demands from different users.

That is, before the shell fabric B 20 and the lining fabric C 30 are combined, one or more of printing, embroidery, laser cutting and dyeing and finishing are carried out on the shell fabric B 20.
By performing printing, embroidery, laser cutting or dyeing and finishing processes on the shell fabric B 20, the shell fabric B 20 can be more three-dimensional and diversified in shape or pattern, so that the produced cap can be more diversified and three-dimensional in appearance as well, and thereby satisfying the demands of different users on different appearances of caps.
According to the present invention, for tighter and firmer bonding between the shell fabric B 20 and the lining fabric C 30, preferably, in Step 1 the shell fabric B 20 and the lining fabric C 30 can be stuck or sewed together. As a preferred embodiment of the present invention, in Step 1 the shell fabric B 20 and the lining fabric C 30 are stuck together by adhesive, and the adhesive is one or more of environment-friendly resin, TPU and hot melt adhesive.
For more attractive and elegant appearance, preferably, formed from the fabric A 10 by thermoplastically shaping in Step 3, the cap is then processed by shape correction. By carrying out shape correction on the cap, deformed parts of the cap which are caused during the production process can be corrected, such that the cap produced can be in consistence with the designed shape, for better appearance.
