Description

Technical Field

[0001] The present invention relates to the technical field of double - layer fabrics and their weaving processes, and in particular, to a double - layer fabric with a pop - up storage structure and its weaving method on a loom. Background Art

[0002] The existing double - layer fabric technology has demonstrated its good performance in many application fields. Specifically, the implementation methods of double - layer fabric technology can include the following cases: (1) Different fiber materials are used for the upper and lower layers. For example, elastic fibers are used for the lower layer, enabling the fabric to have good elasticity in the weft direction. At the same time, wrinkles are formed on the surface of the fabric, presenting a novel visual style. This design is not limited to the clothing field and can be widely applied to other industries; (2) The upper and lower layers are interwoven to form a hollow cavity. For example, a medical hydrophobic nanofiber membrane is filled in the cavity. This medical hydrophobic nanofiber membrane can effectively block the penetration of bacteria and exhibits excellent antibacterial properties, suitable for protective use in medical environments; (3) Filling with functional materials. For example, polyethylene terephthalate yarns are placed into the hollow cavity of the fabric. Polyethylene terephthalate yarns have excellent elasticity and strength, which can significantly improve the overall appearance and service life of the fabric.

[0003] Therefore, the existing technology mainly uses yarn materials with different properties and different filling methods to enable double - layer fabrics to achieve various specific functions. For example, enabling double - layer fabrics to achieve specific visual texture effects or improving their antibacterial, breathable, and other properties. However, the unique mechanical and physical properties of the existing technology have not been fully utilized, especially in terms of the function of storing and popping out items, and there are obvious limitations.

[0019] Although the existing double-layer fabric technology has demonstrated its good performance in multiple application fields, however, its unique mechanical and physical properties have not been fully utilized. Especially in the function of storing and ejecting items, there are obvious limitations. In view of this, the present application provides a double-layer fabric with a pop-up storage structure and its weaving method. By making full use of the unique properties of the double-layer fabric, combining elastic materials and a preset harnessing plan and pattern plate, a double-layer fabric with a pop-up storage structure can be woven. Moreover, the pop-up storage structure has efficient storage and convenient ejection functions.

[0020] According to an embodiment of the present application, the present application provides a double-layer fabric with a pop-up storage structure. The double-layer fabric is obtained by weaving two sets of warp yarns and two sets of weft yarns according to a preset harnessing plan and pattern plate. The two sets of warp yarns include surface warp elastic yarns and ground warp inelastic yarns, and the two sets of weft yarns include surface weft elastic yarns and ground weft inelastic yarns. The tensile force difference between the surface warp elastic yarns and the ground warp inelastic yarns and between the surface weft elastic yarns and the ground weft inelastic yarns is 35%-55%. The obtained double-layer fabric surface has a plurality of pop-up storage structures. When an external force is applied, the pop-up storage structures are used to expand along the preset path positions in the pattern plate to form a temporary open access channel. When not in use, the pop-up storage structures are used to automatically return to the initial compact state.

[0021] According to an embodiment of the present application, as can be seen from FIGS. 1-(a) to 1-(c), by applying an external force (such as a pinching and squeezing method) to the pop-up storage structure, the pop-up storage structure can be unfolded along the preset path position in the pattern diagram to form a temporary open access passage. At this time, the items stored in the pop-up storage structure are ejected outward through the temporary open access passage under the condition of being subjected to an external force, so as to realize the efficient storage and convenient ejection functions of the pop-up storage structure; in addition, after the items in the pop-up storage structure are ejected outward, when not in use, the pop-up storage structure can automatically return to its initial compact state due to the use of highly elastic spandex yarn.

[0022] According to an embodiment of the present application, the counts of the surface warp elastic yarn, ground warp inelastic yarn, surface weft elastic yarn, and ground weft inelastic yarn are 70 / 2 - 38 / 2 NM, the density of the surface warp elastic yarn and ground warp inelastic yarn is 220 - 280 ends / 10 cm, and the density of the surface weft elastic yarn and ground weft inelastic yarn is 220 - 280 ends / 10 cm.

[0023] According to an embodiment of the present application, the surface warp elastic yarn and surface weft elastic yarn are spandex yarns, and the ground warp inelastic yarn and ground weft inelastic yarn are cotton yarns. It should be noted that other highly elastic yarns can also be selected to replace the spandex yarns, as long as the tensile force difference between the surface warp elastic yarn and the ground warp inelastic yarn and between the surface weft elastic yarn and the ground weft inelastic yarn is 35% - 55%, so as to form a pop-up storage structure with an adjustable storage space size. At the same time, the shape of the pop-up storage structure can be designed as an oval, square, triangle, etc., and can be flexibly set according to actual needs, and will not be limited here.

[0024] According to an embodiment of the present application, by adopting a combination of spandex yarn and cotton yarn, a double-layer fabric with both elasticity and comfort can be formed. Among them, the surface warp elastic yarn is made of spandex yarn, which not only enhances the elasticity and toughness of the double-layer fabric but also improves its wear resistance. The ground warp inelastic yarn is made of cotton yarn, which can endow the double-layer fabric with good air permeability and a comfortable touch.

[0025] In summary, the double-layer fabric with a pop-up storage structure provided by the present application has the following improved effects compared with the existing double-layer fabrics: 1. In terms of material selection and matching: By reasonably selecting and matching materials and weaving with two sets of warp yarns with a large difference in tensile force, a pop-up storage structure with an adjustable storage space function can be formed, effectively optimizing the space utilization rate of the double-layer fabric and improving the storage efficiency of traditional fabrics; 2. Application of elastic materials: Using high-elastic spandex yarns as the surface warp elastic yarns and surface weft elastic yarns can form a pop-up storage structure with an adjustable storage space function and a convenient pop-up function, enabling the double-layer fabric to adaptively adjust the size of the storage space when stressed and popped, not only improving the flexibility of storage but also enhancing the convenience of inserting and popping items, so as to solve the deficiencies in the adjustment and elasticity of the filling material in the prior art and improve its strain capacity; 3. Improvement of the space structure: Through pop-up storage structures in various distribution forms, and the pop-up storage structure can be designed into various shapes such as oval, square, triangle, etc., which can flexibly accommodate items of suitable shapes and sizes, so as to improve the flexibility during use and significantly enhance the fluency, convenience and interesting pop-up property of use.

Repeat the warping cycle until all the warp yarns are warped.

[0029] According to an embodiment of the present application, in a warping cycle, the specific warping method is as follows: from left to right, the first warp yarn is to thread 1 surface warp elastic yarn into the first heddle eye of the 1st heddle frame, the second warp yarn is to thread 1 ground warp inelastic yarn into the first heddle eye of the 13th heddle frame, the third warp yarn is to thread 1 surface warp elastic yarn into the first heddle eye of the 2nd heddle frame, the fourth warp yarn is to thread 1 ground warp inelastic yarn into the first heddle eye of the 14th heddle frame, the fifth warp yarn is to thread 1 surface warp elastic yarn into the first heddle eye of the 3rd heddle frame, the sixth warp yarn is to thread 1 ground warp inelastic yarn into the first heddle eye of the 15th heddle frame, and so on until a warping cycle is completed; then, repeat the warping cycle until all the warp yarns are warped.
