Problems solved by technology

However, the suture connection formed in this way has the disadvantage that one of the sutures easily enters from the outside on both sides of the suture connection, so there is still a risk of leakage at the suture site, for example, if the glue is become porous over time, or due to frequent washing or have defective parts, there is the risk of the above

[0057] A three-layer laminate is provided to form a suture-connected structure. The three-layer laminate is a commercially available product sold by W.L. Gore & Associates GmbH of Putzbrunn, Germany under the trade name Gore Liquid Proof Gown Fabric). The laminate has a basis weight of 65g / m 2 The first layer of textile is polyester, and the basis weight is 50g / m 2 A second layer of polyester textile. A porous membrane of expandable PTFE (ePTFE) is arranged between two textile layers. The laminate has a 170g / m 2 The basis weight and the thickness of about 310-330μm.

[0058] The two fabrics of the 3-layer laminate are joined to each other to form a seam-joined structure according to the invention. According to the present invention, the first suture and the second suture are sewn with a commercial sewing machine. The width of the suture covering part 2 is about 10-15mm. In comparison, common suture tapes have suture widths between 22-23 mm. For the liquid-tight sealin...

Abstract

The invention relates to a stitched seam structure (1) comprising a first material web (10) having a first barrier layer (42) and a first edge (14) that is on the outer contour of the first material web (10), a second material web (30) having a second barrier layer (42) and a second edge (34) that is on the outer contour of the second material web (30), and at least one seam (21) that joins the first and the second material webs (10, 30) in a seam area (3) thus forming a first seam allowance (13) between the seam (21) and the first edge (14) of the first material web (10) and forming a second seam allowance (33) between the seam (21) and the second edge (34) of the second material web (30). The first and the second material webs (10, 30) are arranged on top of each other in the seam region (3), and the second seam allowance (33) is folded about the first edge (14) of the first material web (10) and covers the at least one seam (21), forming a seam covering (2), said seam covering (2) being joined to the first material web (10) in the seam region (3). Said stitched seam structure can also help to produce water-tight activity clothing which are comfortable to wear.

Description

technical field [0001] The invention relates to a seam-joined structure comprising a first material web with a first barrier layer and a second material web with a second barrier layer, and at least one seam connecting the first and second materials in the area of ​​the seam fabric. The present invention also relates to a garment with the seam connection structure and a method for forming such a seam connection structure. Background technique [0002] A garment having a water-permeable outer material can be made waterproof if the garment is provided with a waterproof layer, also commonly referred to as a barrier layer, on the inner side of the outer material. In order to make such clothes both waterproof and water vapor permeable, and therefore make the clothes breathable, a water vapor permeable and water permeable outer material is usually used, and a waterproof and water vapor permeable functional layer (barrier layer) is arranged on the inner side of the outer material....
