[0002] Textile products are necessities of life, and various textile fabrics are made into various articles for use. In people's daily wear, with the advancement of technology, chemical fibers made from various polymer compounds as raw materials have replaced natural fibers for spinning and weaving into various clothing, such as polyester, acrylic, etc. These chemical fibers are mostly extracted from petroleum, and then made into fibers through chemical synthesis and mechanical processing. Polyester fabric is a very common chemical fiber clothing fabric used in daily life. Polyester woven fabric has shortcomings in terms of tear resistance. In addition, people have also put forward higher requirements for the safety of clothing. The antibacterial properties of existing fabrics are usually made by impregnating them with solutions containing antibacterial agents. Antibacterial fabrics such as polyester fibers have shortcomings in terms of water resistance. How to prepare a polyester fabric with good tear resistance, antibacterial effect and water resistance has become a problem to be solved. Utility Model Content

[0003] The utility model aims to provide a tear-resistant and washable polyester fabric, which has the advantages of tear-resistant effect, antibacterial effect and washability.

[0004] In order to solve the above technical problems, the purpose of the utility model is achieved as follows:

[0005] The utility model relates to a tear-resistant and water-resistant polyester fabric, comprising a composite tear-resistant fabric layer, a waterproof and breathable membrane and an antibacterial fabric layer;

[0006] The tear-resistant fabric layer is a planar three-dimensional fabric, which is formed by interweaving a first yarn, a second yarn, and a third yarn at a 60° angle; the first yarn and the second yarn include polyester DTY filaments, and the third yarn is a twisted polyester DTY filament and CoPET / PET polyester fiber yarn;

[0007] The antibacterial fabric layer is interwoven with warp yarns and weft yarns, and both the warp yarns and weft yarns include fourth yarns and fifth yarns arranged alternately. The fourth yarn includes ultra-high molecular weight polyethylene filaments and antibacterial polyester filaments and CoPET / PET polyester fiber yarns coated on the outside of the ultra-high molecular weight polyethylene filaments; the fifth yarn includes golden yellow fiber yarns and mugwort fiber yarns twisted in parallel.

[0008] On the basis of the above solution and as a preferred solution of the above solution: the waterproof and moisture-permeable membrane is a PTFE microporous membrane.

[0009] On the basis of the above solution and as a preferred solution of the above solution: the fineness of the ultra-high molecular polyethylene filament is 400D.

[0010] On the basis of the above solution and as a preferred solution of the above solution: the first yarn and the second yarn further include nylon 6DTY filaments twisted with polyester DTY filaments.

[0011] On the basis of the above scheme and as a preferred scheme of the above scheme: the side of the antibacterial fabric layer 3 away from the waterproof and breathable membrane is compounded with a skin-friendly fabric layer; the skin-friendly fabric layer is interwoven with triacetate filaments and cuprammonium filaments twisted together.

[0012] The present invention has the following beneficial effects: the tear-resistant and washable polyester fabric of the present invention employs a flat three-dimensional fabric with excellent tear resistance. Furthermore, the CoPET / PET polyester fiber used has a surface layer of low-melting-point polyester that, after heat treatment, bonds with adjacent yarns, reducing yarn slippage. Furthermore, the antibacterial polyester filament, golden filament yarn, and wormwood fiber yarn employed in the antibacterial fabric are washable. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0018] Example 1

[0019] Combine Figure 1 The present embodiment is described in detail. The tear-resistant and water-resistant polyester fabric involved in the present embodiment comprises a tear-resistant fabric layer 1, a waterproof and breathable membrane 2, and an antibacterial fabric layer 3 which are laminated by a hot melt adhesive mesh.

[0020] The tear-resistant fabric layer 1 is a planar triaxial fabric, composed of first, second, and third yarns 11, 12, and 13 interwoven at 60° angles. The first and second yarns 11, 12 comprise polyester DTY filaments, while the third yarn 13 is a twisted polyester DTY filament and CoPET / PET polyester fiber yarn. Most woven fabrics are made by interweaving yarns in two perpendicular directions. When a fabric is subjected to tension at a 45° angle to the warp or weft, its tensile modulus differs significantly from that when subjected to forces in the warp or weft directions. Furthermore, the shear resistance of conventional two-dimensional fabrics differs significantly in the axial direction compared to that in the 45° direction. However, because a planar triaxial fabric is composed of three yarn systems interwoven at 60° angles, it possesses the unique property of isotropy. This means that regardless of the direction of force applied to the fabric, its deformation is uniform in all directions. Therefore, three-way fabrics do not have the shear and tensile weaknesses of two-way fabrics. In addition, when three-way fabrics are subjected to impact, their deformation presents a fairly uniform equivalent strain.

[0021] In addition, CoPET / PET polyester fiber has a skin-core structure, with the core layer being PET and the skin layer being CoPET. The surface layer of CoPET has a low melting point and melts when heated, bonding with adjacent fibers or yarns, thereby preventing the yarn from slipping when torn.

[0022] The antibacterial fabric layer 3 is interwoven with warp and weft yarns, each of which includes alternating fourth and fifth yarns. The fourth yarn includes ultra-high molecular weight polyethylene filaments and antibacterial polyester filaments and CoPET / PET polyester fiber yarns coated on the outside of the ultra-high molecular weight polyethylene filaments; the fifth yarn includes co-twisted gypsophila fiber yarns and wormwood fiber yarns. The antibacterial polyester filaments used are those in which an antibacterial agent is added to the melt during the melt spinning process, while the gypsophila fiber yarns and wormwood fiber yarns are both produced by adding gypsophila extract and wormwood extract to the solution during the production of viscose fiber, resulting in a long-lasting antibacterial effect on the yarns.

[0023] Furthermore, the waterproof and breathable membrane 2 is a PTFE microporous membrane. The fineness of the ultra-high molecular polyethylene filament is 400D.

[0024] Example 2

[0025] Combine Figure 3 The present embodiment is described in detail. The tear-resistant and water-resistant polyester fabric of the present embodiment is different from the first embodiment in that the first yarn 11 and the second yarn 12 further comprise nylon 6DTY filaments twisted with polyester DTY filaments.

[0026] Another difference from the embodiment is that the antibacterial fabric layer 3 is compounded with a skin-friendly fabric layer 4 on the side away from the waterproof and breathable membrane 2; the skin-friendly fabric layer 4 is formed by twisting triacetate filaments and cuprammonium filaments in parallel.

[0027] The above describes in detail the preferred embodiments of the present invention. It should be understood that those skilled in the art can make numerous modifications and variations based on the concepts of the present invention without inventive effort. Therefore, any technical solutions that can be derived by those skilled in the art based on the concepts of the present invention through logical analysis, reasoning, or limited experimentation based on the existing technology should be within the scope of protection defined by the claims.
