DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a soft, transparent pig rawhide (butakikawa) string suitable as a material for knitted fabrics, handicraft materials and other products.

[0002]

2. Description of the Related Art Conventionally, pig rawhide has been so hard that it cannot be cut into a thin and long string. No pork hides are provided for this purpose.

[0003] The conventionally known pig rawhide treated with hydrochloric acid has a yellowish tint, and the pig rawhide due to sulfuric acid treatment has become cloudy.

Therefore, the present inventor has been conducting research on producing a highly transparent pig rawhide which does not have the above-mentioned yellowish tinge or stickiness. In this study, they found that formic acid was remarkably effective during trial and error, and that it became soft and easy to cut by using glycerin.

[0005]

DISCLOSURE OF THE INVENTION The present invention relates to a novel pig rawhide string which can reliably produce a soft type pig rawhide string having a remarkably high transparency without yellowing or smearing. It is intended to provide a manufacturing method of the above.

[0006]

In order to achieve the above-mentioned object, a method for producing a raw pig hide string according to the present invention comprises preparing a raw pig skin with a watering step, a backing step, a calcifying step and a demineralizing step. A formic acid treatment step is performed on the ready-prepared raw hide that has been subjected to this preparation step, and the formic acid-completed raw hide is subjected to a board-drying and net-drying step, followed by a draining step and a draining step. After infiltration of an appropriate amount of glycerin into the subsequent rawhide, the rawhide impregnated with the glycerin is again boarded and subjected to a drying process such as netting to obtain a soft type pig rawhide, and then cutting the pig rawhide into a thin string. To get the finished product.

[0007]

[Effect] The formic acid treatment eliminated the yellowish color and the smell, and became soft with glycerin.

[0008]

According to the method for producing a pig rawhide string according to the present invention, a soft pig rawhide string having remarkably high transparency can be produced reliably and easily, and the intended purpose can be sufficiently achieved. Can be achieved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment according to the present invention comprises a rinsing step for washing, absorbing and softening skin, and removing water-soluble proteins from raw pig skin, and a subcutaneous layer of an unnecessary fat layer on the meat surface. The preparation process is completed by performing the lining process for removing the hair, the calcification process for removing the hair and epidermis layer and swelling the skin tissue, and the decalcification process for removing the lime and unnecessary proteins in the listed order. Then, a formic acid treatment step is applied to the ready-prepared raw hide that has been completed in this preparation step, and then a tensioning step is performed by boarding and drying, so that a slightly hard type of pig rawhide is obtained. Perform the process, then
An appropriate amount of glycerin is impregnated in the raw hide after draining, and then the raw hide impregnated with glycerin is subjected to a boarding process to dry the raw hide, thereby obtaining a soft-type pork hide and thinning the soft-type pork hide. A long cord-like cutting and winding are performed to obtain a finished product 1. The dyeing step may be performed at an appropriate time.
