Detailed Description

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

In order to make the objects, features and advantages of the present invention more obvious and understandable, the drawings in the embodiments of the present invention are combined below to clearly and completely describe the technical solutions in the embodiments of the present invention, and obviously, the embodiments described below are only some embodiments of the present invention, but not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the present invention.

Example one

The present embodiment will be described in detail with reference to fig. 1, 2 and 3. The waterproof and moisture permeable oxford for the luggage comprises a base fabric layer 1 and a waterproof and moisture permeable film layer 2. The base cloth layer 1 is an oxford fabric formed by interweaving warps and wefts, and the waterproof moisture-permeable film layer 2 is a TPU/PAN double-component waterproof moisture-permeable film sprayed on the surface of the base cloth layer 1 by adopting an electrostatic spinning method. The thickness of the waterproof moisture-permeable film layer 2 is 0.15-0.3 mm.

The oxford used as the case sometimes drenches rainwater, and the rainwater can have certain erosion effect on the fabric, namely, how to make the used oxford capable of preventing water, moisture and rainwater during use. The waterproof moisture-permeable fabric mainly comprises three types of high-density fabrics, coating fabrics and laminated fabrics. In which a high-density fabric is poor in moisture permeability but water resistance. The laminated fabric has a waterproof moisture-permeable functional film, so that the laminated fabric has a good waterproof moisture-permeable function. But the conventional waterproof moisture-permeable film does not prevent the erosion of rainwater. The TPU/PAN two-component waterproof moisture-permeable membrane used in the embodiment contains two materials of TPU and PAN. The TPU has good hydrophilicity, higher strength and elasticity. PAN has good chemical corrosion resistance, can resist the corrosion of chemical components in rainwater after being wetted by rainwater, and ensures that the used oxford fabric has good protective performance on the premise of having good waterproof and moisture permeable effects.

In this embodiment, the warp yarn used in the base fabric layer 1 is an elastic core-spun yarn, and includes a core layer 11 and a covering layer 12. The core layer 11 is an elastic filament. The coating layer 12 is terylene FDY150D/36F, and the weft is terylene FDY 150D/36F. The warp and weft density was 360X 210 pieces per 10 cm.

Further, in this embodiment, the elastic filament includes a core-sheath inner layer 111 and a sheath outer layer 112, the core-sheath inner layer 111 is polyurethane, and the sheath outer layer 112 is PET. The ratio of the radius of the core-sheath inner layer 111 to the thickness of the sheath outer layer 112 is 5: 1-1: 5, in particular 1: 2. in this embodiment, since the weft yarn and the covering layer 11 are made of dacron, the sheath outer layer 112 of the elastic filament is also made of dacron, so that defects do not occur during dyeing.

Since the base fabric layer 1 has elasticity and the TPU/PAN bicomponent waterproof moisture-permeable film also has certain elasticity, when the TPU/PAN bicomponent waterproof moisture-permeable film is sprayed on the surface of the base fabric layer 1, the base fabric layer 1 needs to be sprayed in a stretched state, and the stretched elongation is half of the maximum elongation.

Example two

The present embodiment will be described in detail with reference to fig. 1, 2 and 3. The waterproof and moisture permeable oxford for the luggage according to the present embodiment is different from the first embodiment in that the covering layer 12 is 200D nylon air textured yarn, and the weft is 160D nylon air textured yarn in the present embodiment. The elastic filament comprises a core-sheath inner layer 111 and a sheath outer layer 112; the core-sheath inner layer 111 is made of polyurethane, and the sheath outer layer 112 is made of nylon 6 or nylon 66. The sheath 12, the weft and the sheath 112 of the elastic filaments are made of nylon so that no defects occur during dyeing.

EXAMPLE III

This embodiment will be described in detail with reference to fig. 4. In the waterproof moisture-permeable oxford for the case and bag related to the embodiment, the other side of the base fabric layer 1 is bonded with an elastic fabric layer 4 through a water-based polyvinyl chloride bonding layer 3, and the elastic fabric layer 4 is formed by interweaving cotton-ammonia core-spun yarns and pure cotton yarns. The cotton-ammonia core-spun yarn is warp yarn. The water-based polyvinyl chloride bonding layer 3 is in an array of dots.

The foregoing has described in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be devised by those skilled in the art in light of the present teachings without departing from the inventive concepts. Therefore, the technical solutions that can be obtained by a person skilled in the art through logic analysis, reasoning or limited experiments based on the prior art according to the concepts of the present invention should be within the scope of protection defined by the claims.
