[0020] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following description is given in conjunction with the embodiments and the accompanying drawings.

[0021] Please refer to Figure 1 A three-dimensional woven fabric comprises an upper membrane layer, a base fabric and a lower membrane layer arranged in sequence from top to bottom, the base fabric comprises a surface layer, a middle layer and a bottom layer, the surface layer is woven from a first warp yarn and at least one shuttle weft yarn, and the bottom layer is woven from a second warp yarn and at least one shuttle weft yarn; the middle layer comprises a drawing wire, and the two ends of the drawing wire are respectively interwoven with the surface layer and the bottom layer.

[0022] From the above description, it can be seen that the beneficial effect of the present invention is that: the present invention forms a wire drawing connecting the surface layer and the bottom layer between the surface layer and the bottom layer, and the surface layer, the bottom layer and the wire drawing are integrated to form a wire drawing base cloth. The wire drawing base cloth has a simple structure and is easy to weave. It can be bonded to the membrane material without water-soluble treatment to obtain a wire drawing inflatable cloth.

[0023] Furthermore, the wire drawing is evenly arranged in the axial direction of the weft yarns of the surface layer and the bottom layer.

[0024] Furthermore, the drawn yarn is a second warp yarn separated from the bottom layer tissue and woven with the weft yarn in the surface layer.

[0025] The interpretation of being separated from the underlying tissue is: being separated from the underlying weaving tissue and not participating in the weaving of the underlying weaving tissue, that is, the effect of missed stitches.

[0026] From the above description, it can be seen that in the present invention, the second warp yarn is separated from the bottom layer tissue and woven with the weft yarn in the surface layer to form a wire drawing connecting the surface layer and the bottom layer. The integration effect of the surface layer, the bottom layer and the wire drawing is better, and the base fabric structure is more reliable.

[0027] Furthermore, the second warp yarn is separated from the bottom layer tissue every at least five stitches and is woven with the weft yarn in the surface layer.

[0028] Furthermore, the second warp yarn is separated from the base weave every eight to sixteenth stitch and woven with the middle weft yarn of the surface layer. If every five stitches are separated from the base weave and woven with the middle weft yarn of the surface layer, the first stitch, the seventh stitch, the thirteenth stitch, and so on are separated from the base weave and woven with the middle weft yarn of the surface layer in this order.

[0029] From the above description, we can see that if the number of dropped stitches is too small, the drawing length is too short and the inflation effect is poor; if the number of dropped stitches is too large, the gaps in the bottom layer are obvious, which not only affects the appearance but also the airtightness after the film is applied is poor.

[0030] Furthermore, the warp density of the surface layer and the bottom layer is ≥28 strands / cm.

[0031] Furthermore, the D number of the warp yarns of the surface layer and the bottom layer is ≤100.

[0032] Furthermore, the weft density of the surface layer and the bottom layer is ≥16 threads / cm.

[0033] Furthermore, the D number of the weft yarns of the surface layer and the bottom layer is ≤150.

[0034] As can be seen from the above description, the present invention controls the length of the drawn yarns, thereby controlling the height of the inflated fabric, by adjusting the warp density and drop stitch spacing of the bottom layer. The present invention utilizes higher warp and weft densities, resulting in a finer, more tightly arranged warp and weft yarns, making the fabric less prone to tearing. Furthermore, since both ends of the warp yarn are pulled during the weaving process, exerting greater force, the warp density must be greater than the weft density to prevent warp breakage.

[0035] Furthermore, the second warp yarns separated from the bottom layer are evenly arranged in the axial direction of the weft yarns of the surface layer and the bottom layer.

[0036] Furthermore, the second warp yarn separated from the bottom layer tissue connects the surface layer and the bottom layer in an oblique line or a straight line.

[0037] Furthermore, gas is filled between the upper film layer, the base fabric and the lower film layer.

[0038] From the above description, it can be seen that the upper membrane layer and the lower membrane layer seal the base fabric, and gas is filled between the membrane layer, the base fabric and the lower membrane layer to obtain a three-dimensional woven fabric (inflatable brushed fabric).

[0039] Please refer to Figure 1 , Embodiment 1 of the present invention is: a three-dimensional woven fabric, which is composed of an upper film layer 1, a base fabric and a lower film layer 5 arranged in sequence from top to bottom, and gas is filled between the upper film layer 1, the base fabric and the lower film layer 5;

[0040] The base fabric consists of a surface layer 2, a middle layer 3 and a bottom layer 4; the surface layer 2 is woven from a shuttle weft yarn and a first warp yarn 21, the warp density of the surface layer 2 is 28 strands / cm, and the weft density of the surface layer 2 is 16 strands / cm; the bottom layer 4 is woven from a shuttle weft yarn and a second warp yarn 41, the warp density of the bottom layer 4 is 28 strands / cm, and the weft density of the bottom layer 4 is 16 strands / cm, the warp yarn D number of the surface layer 2 and the bottom layer 4 is 100, and the weft yarn D number is 150; the middle layer 3 is composed of a second warp yarn 41 that is separated from the bottom layer 4 tissue and woven with the weft yarn in the surface layer 2, the second warp yarn 41 is separated from the bottom layer 4 tissue every twelve stitches and woven with the weft yarn in the surface layer 2, the second warp yarn 41 that is separated from the bottom layer tissue is evenly arranged in the axial direction of the weft yarns of the surface layer 2 and the bottom layer 4, and the second warp yarn 41 that is separated from the bottom layer tissue connects the surface layer 2 and the bottom layer 4 in a straight line.

[0041] The second embodiment of the present invention is:

[0042] The only difference between Example 2 and Example 1 is that: the surface layer 2 is woven from two shuttle weft yarns and the first warp yarn 21, and the bottom layer 4 is woven from two shuttle weft yarns and the second warp yarn 41; the warp density of the surface layer 2 is 30 strands / cm, and the weft density of the surface layer 2 is 18 strands / cm; the warp density of the bottom layer 4 is 30 strands / cm, and the weft density of the bottom layer 4 is 18 strands / cm; the warp yarn D number of the surface layer 2 and the bottom layer 4 is 90, and the weft yarn D number is 140; the second warp yarn 41 is separated from the bottom layer 4 tissue every eight stitches and is woven with the weft yarn in the surface layer 2, and the second warp yarn 41 separated from the bottom layer tissue connects the surface layer 2 and the bottom layer 4 in an oblique line.

[0043] The third embodiment of the present invention is:

[0044] The only difference between Example 3 and Example 1 is that the surface layer 2 is woven with eight shuttle weft yarns and the first warp yarn 21, and the bottom layer 4 is woven with eight shuttle weft yarns and the second warp yarn 41; the second warp yarn 41 is separated from the bottom layer 4 tissue every eighteen stitches and woven with the weft yarn in the surface layer 2.

[0045] To sum up, the three-dimensional woven fabric provided by the utility model adopts the upper membrane layer and the lower membrane layer to bond the surface layer and the bottom layer to achieve a sealing effect, and fills gas between the membrane layer, the base cloth and the lower membrane layer to obtain a three-dimensional woven fabric; wherein the base cloth is separated from the bottom layer tissue by the second warp yarn and woven with the weft yarn in the surface layer to form a brushed base cloth that integrates the surface layer, the bottom layer and the brushing. The base cloth controls the length of the brushing by adjusting the warp density and the missed needle interval of the bottom layer, thereby controlling the height of the fabric after inflation. The structure is simple, the weaving is convenient, and the brushed inflatable cloth can be obtained by bonding the membrane material without water-soluble treatment.
