In order to manufacture a mask capable of adjusting the length of a wear string according to the present invention, first, a first formed extending outward from both ends of the cover member 30 and the cover member 30 using a filter material such as cloth or non-woven fabric, Two-string coupling members (33a, 33b) is formed in the form of an integrally formed mask body portion (S10).

As described above, when the forming of the mask body part is completed in step S10, the first wearing strap 40 and the second wearing strap 50 having two annular rings formed by crossing one annular string at the middle as described above are interposed. Each of the first strap coupling member 33a and the second strap coupling member 33b is disposed on inner surfaces (S20).

In this case, the inner surfaces of the first strap engaging member 33a and the second strap engaging member 33b are connected to two annular rings 41 and 42 of the first wearing strap 40, respectively, as described above. The connection portion (not shown) of the two annular rings 51 and 52 of the 43 and the second wearing strap 50 is disposed.

When the step S20 is completed, the first strap coupling member 33a is covered with the cover member 30 such that the inner surface of the first strap coupling member 33a surrounds the outer surfaces of the two annular rings 41 and 42. ) After bending in the inner direction, the end is coupled to one side of the left end of the cover member 30, and in the same manner, the end of the second string engaging member 33b is one end of the right side of the cover member 30. It will be coupled to (S30).

As described above, the mask capable of adjusting the length of the wear string according to the present invention simply crosses the annular wear string, which was generally used in the conventional mask, once in the middle so that two rings are formed, and then masks the crossed part. Since it is configured to be coupled to the main body, it is configured to be able to adjust the length of the wearing strap without adding a separate strap length adjusting member, so that the manufacturing cost of the mask can be greatly reduced as compared to a conventional strap length-adjustable mask. Due to the simplification of the process, there is an advantage that mass production is significantly facilitated.
