[0036] In order to more clearly illustrate the present invention and clarify its technical implementation plan, the present invention will be described in detail below with reference to specific implementation cases and drawings, but the implementation plans provided should not be considered as limiting.

[0037] Example 1

[0038] like Figure 1 As shown in Figures 1(a) and 1(b), the semi-enclosed flame-retardant, anti-static one-piece garment of the present invention comprises a body composed of several stitched and sewn garment panels. The panels are all made of flame-retardant, anti-static fabric composed of aramid and conductive fibers, with the aramid fiber content being 98% and the conductive fiber content being 2%.

[0039] After the two pieces of fabric are sewn together, flat stitching is used to sew them together. The seam between the two pieces of fabric is provided with a conductive continuity structure 6, as shown in FIG. 2(a). After flat stitching, the two pieces of fabric form a flat stitching layer 61. An adhesive layer 62 is provided on the surface of the flat stitching layer 61. A conductive reinforcing layer 63 is provided on the surface of the adhesive layer 62. As shown in FIG. 2(b), the flat stitching layer 61 includes a straight seam formed after the two pieces of fabric are sewn together and a seam portion formed on the opposite side of the seam. The seam portion is ironed to the two sides of the fabric and adheres thereto. As shown in FIG. 2(c), the adhesive layer 62 is in the shape of a strip and is in the shape of a rectangle. The adhesive layer 62 is made of hot melt double-sided adhesive tape or double-sided adhesive lining. As shown in FIG. 2(d), the conductive reinforcing layer 63 includes two layers. One layer is a metal foil tape 64, and the other layer is a fabric base 65. The centers of the two layers are aligned.

[0040] After the two pieces of fabric are sewn together, flat stitching is used to sew them together. The seam between the two pieces of fabric is provided with a conductive continuity structure 6, as shown in FIG. 2(a). After flat stitching, the two pieces of fabric form a flat stitching layer 61. An adhesive layer 62 is provided on the surface of the flat stitching layer 61. A conductive reinforcing layer 63 is provided on the surface of the adhesive layer 62. As shown in FIG. 2(b), the flat stitching layer 61 includes a straight seam formed after the two pieces of fabric are sewn together and a seam portion formed on the opposite side of the seam. The seam portion is ironed to the two sides of the fabric and adheres thereto. As shown in FIG. 2(c), the adhesive layer 62 is in the shape of a strip and is in the shape of a rectangle. The adhesive layer 62 is made of hot melt double-sided adhesive tape or double-sided adhesive lining. As shown in FIG. 2(d), the conductive reinforcing layer 63 includes two layers. One layer is a metal foil tape 64, and the other layer is a fabric base 65. The centers of the two layers are aligned.

[0041] The conductive continuity structure 6 is ironed at high temperature. The adhesive layer 62 dissolves into a viscous colloid under the action of high temperature, thereby realizing the adhesion of the flat stitching layer 61 and the conductive reinforcing layer 63 of the fabric. After the flat stitching layer 61 and the conductive reinforcing layer 63 of the fabric are adhered together through the adhesive layer 62, double fixation is realized on the surface of the flat stitching layer 61 through conductive sewing thread. The conductive sewing thread is symmetrically located on both sides of the seam of the flat stitching layer 61 and passes through the fabric base 65, the adhesive layer 62, the seam portion of the flat stitching layer 61, and the fabric of the flat stitching layer 61 in turn from top to bottom.

[0042] The conductive sewing thread seam 66 is parallel to the seam, and the distance between the two is 0.4 cm. The thread density of the seam is 4 stitches / cm. The fabric is connected by conductive sewing thread during sewing. The conductive sewing thread is silver fiber conductive sewing thread, and the resistivity is less than 10 Ω / cm. The use of conductive sewing thread to fix the fabric can further improve the conductive performance of the seam, which is conducive to dissipating static charges on the surface of the garment and further improving the anti-static performance. The metal foil tape in the conductive reinforcing layer has high softness and conductive performance, which enhances the conductive performance. The combination of the three layers can compensate for the influence of the broken conductive network caused by the seam gap of the fabric, thereby improving the protective effect.

The fabric pieces are made of flame-retardant and anti-static fabric, which is composed of aramid fiber and conductive fiber. The content of aramid fiber is 98%, and the content of conductive fiber is 2%.

[0046] After the pieces of fabric are sewn together, flat sewing is used to sew the pieces of fabric together. As shown in FIGS. 3(a) and 3(b), after flat sewing, two pieces of fabric form a flat sewing layer 61. The flat sewing layer 61 includes a straight-line seam formed after the two pieces of fabric are sewn together and two seam portions formed on both sides of the seam. The seam portions are ironed to the two sides of the pieces of fabric and are attached to the two sides of the pieces of fabric. An adhesive layer 62 is arranged on the surface of the seam portions on both sides of the flat sewing layer 61. The adhesive layer 62 is in the shape of a strip and is rectangular. The width of the adhesive layer 62 is twice the width of the seam portions of the flat sewing layer 61.

The metal foil tape 64 is arranged on the surface of the piece of fabric 65 to form the electrically conductive reinforcing layer 63. The metal foil tape 64 is made of copper foil tape, aluminum foil tape, or nickel foil tape. The width of the metal foil tape 64 is less than 0.5 times the width of the seam portions of the piece of fabric. The thickness of the metal foil tape 64 is less than 0.1 mm. The width of the piece of fabric 65 is more than 3 times the width of the seam portions of the piece of fabric.

[0047] Example 3

[0048] Based on Example 1 or 2, the garment pieces in this embodiment include a front body 1, a back body 5, and two left and right sleeves 2. The front body 1 comprises a two-piece continuous structure that is bilaterally symmetrical, divided into a left front body piece and a right front body piece. The upper portion of the front body piece is separated by a placket, with the upper and lower portions of the left front body piece being an integral structure, and the upper and lower portions of the right front body piece being an integral structure. The back body 5 comprises a three-piece non-continuous structure, specifically comprising an upper back portion 51 of the body piece, a lower portion 52 of the left rear body piece, and a lower portion 53 of the right rear body piece. The sleeves 2 are one-piece loose-fitting structures. This structure minimizes the number of cuts of the overall garment pieces while ensuring the integrity of the overall structure and function of the garment, further reducing the impact of the division between the garment pieces on the flame retardant and antistatic properties of the garment.

[0049] Example 4

[0050] On the basis of embodiment 3, this embodiment further includes a waist connecting belt 4, which can adjust the tightness of the waist to improve the wearing comfort of the human body. Figure 5 As shown, the waist connecting belt 4 includes a belt 43, an elastic band 41, and a buckle 42. A slender rectangular belt 43 is cut from the flame-retardant fabric of the garment body and fixed around the waist of the garment body. The belt 43 and the waist fabric of the garment body form a rectangular hole. The elastic band 41 is 1 cm smaller than the width of the belt 43 and 80%-97% of the waist circumference. It runs horizontally through the hole, with both ends protruding from the front of the garment body. The two ends of the elastic band are respectively combined with the parent-child adjustment buckles of the buckle 42. The elastic band is made of flame-retardant aramid or other flame-retardant materials, and the buckle is made of metal. The surface of the buckle is covered with the fabric of the garment body. The elastic band 41 is located on the back of the garment body, covering the surface of the connection between the back of the upper part 51 of the garment body and the lower part 52 of the left back piece and the lower part 53 of the right back piece.

[0051] When in use, the elastic band 41 is connected and closed to the surface of the body placket through the parent-child adjustment buckle of the buckle 42, which is used to adjust the tightness of the waist. The elastic band 41 is made of flame-retardant aramid material, which can further improve the flame retardant performance of the clothing. At the same time, the metal buckle 42 covered with the fabric of the garment piece can enhance the accumulation of electric charge at the waist connecting belt to the inside or surface of the metal buckle 42. When the buckle 42 contacts other parts of the clothing body, it is beneficial to the discharge of electric charge and dissipation on the surface of the clothing body, thereby improving the anti-static performance of the clothing.

V-shaped flame-retardant reflective strips 3 are fixed to the upper back 51 of the front body, with the two ends of the V-shaped flame-retardant reflective strips 3 being connected to the connection points of the sleeves 2 and the upper back 51 of the front body, respectively, forming an M shape when viewed from the back.

[0055] The flame-retardant reflective strips 3 are also fixed to the joints of the legs of the front body, forming continuous circular rings at the joints of the left and right legs.

[0056] The continuous arrangement of the flame-retardant reflective strips 3 on the front body can enhance the visibility of workers during work, further improving safety performance.
