Some hat linings are also made of multiple layers of fabric bonded together to improve various performance such as strength, service life, and comfort.

[0003] When the cap lining is composed of two or more layers of cloth, the layers of cloth need to be bonded and fixed to each other. The commonly used fixing method in the prior art is to glue at several locations on a piece of lining cloth, and then glue it to another piece of lining cloth.

[0004] This fixing method makes the two layers of lining cloth connected at multiple points, resulting in poor connection uniformity and easily causing the two layers of lining cloth to delaminate during subsequent use. Summary of the invention

[0015] The present invention also includes a method for producing the water-washable coated cap lining, and the specific steps are as follows:

[0016] Step 1: Select the raw materials for the rubber film according to the weight proportion, and then heat them to 170°C. All the raw materials except the high temperature resistant rubber particles are melted and mixed. The high temperature resistant rubber particles remain in a solid state and are mixed with other liquid raw materials;

[0017] Step 2: The raw material heated at high temperature is covered on the surface of a layer of lining cloth through a laminating process to form a coating film. After the temperature drops, the raw material re-condenses on the surface of the lining cloth into a solid film, which is the coating film;

[0018] Step 3: Place another layer of lining cloth on the surface of the adhesive film, and bond the adhesive film and the other layer of lining cloth together by hot melting. After the other layer of lining cloth is covered on the surface of the adhesive film, the two layers of lining cloth are squeezed by hot pressing, and the lining cloth is heated at the same time to melt the adhesive film again;

[0019] Step 4: Cool the two layers of lining cloth bonded together by the adhesive film at room temperature, so as to use the adhesive film to bond the two layers of lining cloth to each other, and finally form a washable coated cap lining.

[0020] In the above technical solution, the technical effects and advantages provided by the present invention are:

[0021] 1. A laminating film is added to a layer of lining cloth through the laminating process, and then the laminating film is used to adhere another layer of lining cloth.

[0080] The various raw materials involved in the above-mentioned embodiments 1, 2, 3, 4 and 5 are only different in weight proportions, and the manufacturer models of the various raw materials are the same.

[0082] Five pairs of lining cloths were selected, each pair had two pieces, each lining cloth was 50 cm long and 20 cm wide, and each pair of lining cloths was bonded to each other according to the methods of Examples 1, 2, 3, 4, and 5. Another pair of lining cloths of the same specification was selected and bonded to each other by a traditional glue dispensing method as a control group. When bonding these six pairs of lining cloths, it was necessary to pay attention to bonding only an area of ​​40 cm × 20 cm, leaving an area of ​​10 cm × 20 cm without bonding;

[0083] The same test was performed on the six pairs of lining cloths. The two pieces of lining cloth without adhesion in each pair of lining cloths were pulled in two different directions until the adhesion area was torn apart, so that the two pieces of lining cloths were completely separated. The pulling force required to separate the lining cloths was tested from one direction. After six experiments, the data was sorted out to obtain the following table:

[0085]

[0086] By analyzing the data in the above table, it can be clearly seen that by covering a layer of lining cloth with a covering film and then using the covering film to adhere another layer of lining cloth, the connection strength of the cap lining fabric made in this way is greatly increased compared with the existing technology, which effectively avoids the delamination of the two layers of lining cloth during use;

[0087] In addition, compared with Example 3, the only difference between Example 5 and Example 3 is that no high temperature resistant rubber particles are added to the coating film of Example 5. As can be seen from the table, the strength of the cap lining made in Example 5 is lower than that of Example 3. This shows that adding high temperature resistant rubber particles to the raw material of the coating film can play a supporting role between the two layers of lining cloth, avoiding the melted coating film from being squeezed out from the side of the lining cloth due to excessive extrusion during the hot pressing process, ensuring that there is enough coating film for adhesion between the two layers of lining cloth, thereby more fully and effectively playing the role of the coating film and improving the connection strength of the two layers of lining cloth.

[0088] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that, for those skilled in the art, the described embodiments can be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the above description is illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
