Description

Technical Field

[0001] The utility model relates to the field of textiles, and more specifically, to a warp and weft knitted curtain fabric. Background Art

[0002] Warp and weft knitted fabrics refer to fabrics formed by weaving warp yarns and weft yarns. We also call them woven fabrics or woven fabrics. Because the warp and weft are staggered in the weaving method, the fabric is relatively firm, crisp and not easy to deform. Most of the curtain fabrics on the market are woven by this weaving method.

[0003] Floor-length curtains are one of the curtain styles we often use indoors. The curtain fabric of this type of curtain is generally made of warp and weft woven fabrics. This type of curtain is generally only about 2 cm from the ground, which makes it more visually coordinated and does not appear abrupt, ensuring the coordination between the curtain fabric and the room. This is also a choice that reflects the beauty of the curtains. In order to ensure the overall light-shielding performance of this type of curtain, the overall weaving density of the curtain fabric is high, but the length of this type of curtain is itself long. This setting will cause the overall weight of the curtain fabric to be heavier, making it more difficult to clean later.

[0004] Therefore, new solutions need to be proposed to solve this problem. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model aims to provide a warp and weft knitted curtain fabric.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: a warp and weft knitted curtain fabric, including a base layer, the base layer including a shading part and a weight-reducing part, the number of the weight-reducing parts is two and the two weight-reducing parts are respectively arranged at the upper and lower ends of the base layer, the base layer is woven by warp and weft yarns, wherein the shading part passes through a blocking yarn arranged in the weft direction, the blocking yarn is used to block the gap between any two adjacent weft yarns, the weight-reducing part passes through a twisted yarn arranged in the weft direction, the twisted yarn and the weft yarn are twisted to form a twisted warp hole for the warp yarn to pass through, and a gap is formed between two adjacent warp yarns.

[0007] The utility model is further configured as follows: the blocking yarn comprises a core yarn and a flocking yarn wound around the core yarn, and the flocking yarn is provided with blocking flocks for blocking gaps.

[0008] The utility model is further configured as follows: the core yarn is formed by combining two strands of hollow polyester yarn, and the hollow polyester yarn is formed by twisting a plurality of hollow polyester filaments.

[0009] The utility model is further configured as follows: the number of the flocking yarn wound outside the core yarn is one, and the twist of the flocking yarn wound outside the core yarn is 250-300 turns / meter.

[0010] The utility model is further configured as follows: the warp yarns and the weft yarns are twisted from special-shaped polyester fibers, and the cross-section of the special-shaped polyester fibers is arranged in a triangular shape.

[0011] The utility model is further configured as follows: the skein is formed by twisting polyester fibers, and the diameters of the warp yarn and the weft yarn are both larger than the diameter of the skein.

[0012] In summary, the utility model has the following beneficial effects: the weight-reducing portion is a gauze structure formed by weaving warp yarns, weft yarns and twisted yarns, and the weaving density of the gauze structure is low, so that the overall weight of the weight-reducing portion is lighter, and secondly, under the action of the twisted warp holes, the spacing between two adjacent warp yarns is larger, thereby reducing the density of the warp yarn distribution, which is helpful for reducing the overall weight of the base layer. This arrangement makes the weaving density of the base layer in the part that does not require shading lower, thereby reducing the overall weight of the base layer, and the setting of the blocking yarn blocks the gap between any two adjacent weft yarns, so that the number of sunlight that can pass through the blocking portion is small, thereby ensuring the shading performance of the shading portion and meeting the shading requirements of the curtain cloth.

[0017] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0018] A warp and weft knitted curtain fabric, such as Figure 1 and Figure 2As shown, it includes a base layer, and the base layer includes a shading part 1 and a weight-reducing part 2. There are two weight-reducing parts 2, and the two weight-reducing parts 2 are respectively arranged at the upper and lower ends of the base layer. The base layer is woven by warp and weft yarns 3 and 4, wherein the shading part 1 passes through a blocking yarn 5 arranged in the weft direction, and the blocking yarn 5 is used to block the gap between any two adjacent weft yarns 4. The weight-reducing part 2 passes through a skein 6 arranged in the weft direction, and the skein 6 and the weft yarn 4 are twisted to form a skein hole for the warp yarn 3 to pass through, and a gap 7 is formed between two adjacent warp yarns 3. The area of ​​the weight-reducing part 2 located at the upper end of the base layer is smaller than the area of ​​the weight-reducing part 2 located at the lower end of the base layer. Because only the middle part of the existing floor-length curtain fabric needs to play a shading role, the shading part 1 is arranged at the part close to the middle of the base layer, which ensures the overall shading effect of the base layer, so that the base layer meets the shading requirements, and the weight-reducing part 2 is woven by the warp yarn 3, the weft yarn 4 and the skein 6. The formed gauze structure has a low weaving density, so that the overall weight of the weight-reducing part 2 is lighter. Secondly, under the action of the twisted warp holes, the spacing between two adjacent warp yarns 3 is larger, thereby reducing the distribution density of the warp yarns 3, which is helpful to reduce the overall weight of the base layer. This arrangement makes the weaving density of the base layer in the part that does not require shading lower, thereby reducing the overall weight of the base layer. The setting of the blocking yarn 5 blocks the gap between any two adjacent weft yarns 4, so that the number of sunlight that can pass through the shielding part is small, ensuring the shading performance of the shading part 1. The twisted yarns 6 and weft yarns 4 form a group of 6 yarns, wherein the twisting directions of the yarns 6 and weft yarns 4 in two adjacent groups of 6 yarns are symmetrical. This arrangement makes the pores 7 relatively large, so that the internal and external air can interact through the weight-reducing part 2, which has a certain improvement in the overall air permeability of the base layer.

[0019] like Figure 2 and Figure 3As shown, the blocking yarn 5 includes a core yarn 8 and a flocking yarn 9 wound around the core yarn 8. The flocking yarn 9 is provided with a blocking flock 10 for blocking the gap. The blocking flock 10 is located on the outer peripheral wall of the blocking yarn 5, so that when the blocking yarn 5 passes between two adjacent weft yarns 4, the blocking flock 10 can fill the gap between the blocking yarn 5 and the weft yarn 4 more tightly, thereby ensuring the shielding performance of the blocking yarn 5. The core yarn 8 is formed by two strands of hollow polyester yarn 11, and this arrangement forms a channel formed by two strands of hollow polyester yarn 11 in parallel. This arrangement ensures that the blocking yarn 5 has a larger diameter while the density of the filling inside the yarn core is smaller, and the hollow polyester yarn 11 is made of a number of hollow polyester yarns twisted together, and the density of the hollow polyester yarns is relatively small, so that the overall density of the blocking yarn 5 is relatively small, and this arrangement further reduces the overall weight of the base layer. The number of flocking yarns 9 wound around the core yarn 8 is one, and the twist of the flocking yarn 9 wound around the core yarn 8 is 250-300 turns / m. In this embodiment, the twist of the flocking yarn 9 wound around the core yarn 8 is 250 turns / m. The twist of the flocking yarn 9 wrapped around the yarn core is relatively low and the number is small, which has a certain effect of reducing the overall weight of the blocking yarn 5. The flocking yarn 9 is twisted from low-elastic polyester fiber. This arrangement ensures the overall wear resistance of the flocking yarn 9.

[0020] like Figure 2 As shown, the warp yarn 3 and the weft yarn 4 are both twisted with shaped polyester fibers. The cross-section of the shaped polyester fibers is triangular. The polyester fibers have the characteristics of high strength, which ensures the overall strength of the base layer. The triangular cross-section fibers have a large coverage area and have a certain spectral effect, which improves the overall anti-ultraviolet performance of the base layer. The skein 6 is twisted with polyester fibers. The diameters of the warp yarn 3 and the weft yarn 4 are both larger than the diameter of the skein 6. The overall diameter of the skein 6 is small, which makes the weight of the skein 6 relatively light, ensuring the lightweight characteristics of the weight reduction part 2.

[0021] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
