Description

Technical Field

[0001] This utility model relates to the field of fabrics, and more specifically, to a polyester-viscose fabric. Background Technology

[0002] Although polyester-viscose fabrics on the market have a certain degree of wrinkle resistance, they are formed by interlacing warp and weft yarns using basic weaves such as plain weave, twill weave, or satin weave. As a result, the fabric formed by the interlacing of warp and weft yarns has a straight texture or smooth surface. Therefore, when subjected to external force, the warp and weft yarns cannot adapt to the rapid deformation under stress. Furthermore, when the external force is removed, the warp and weft yarns may not be able to recover quickly due to deformation, which will cause the fabric to deform over a long period of time. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a polyester-viscose fabric. By combining the coarse and fine warp and weft yarns with the wavy weave of the fabric, the warp and weft yarns interweave to form a wavy curved surface structure. Therefore, after the warp and weft yarns are interwoven to form the fabric, their state changes from straight lines to curves and remains curved. Thus, when the fabric is subjected to external force, the warp and weft yarns can adapt to deformation, and when the external force disappears, because the warp and weft yarns are in a curved state, they can quickly return to their original shape, thereby making the fabric wrinkle-resistant. At the same time, the wavy curved surface structure of the fabric forms a smooth curve, thereby reducing the friction on the fabric surface, which not only reduces the formation of wrinkles, but also increases the softness and elasticity of the fabric because the yarns are all in a curved state.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a polyester-viscose fabric, characterized in that it includes a first wave zone and a second wave zone, the first wave zone and the second wave zone are arranged at intervals along the length of the fabric, the first wave zone and the second wave zone each include a wave crest and a wave trough, the wave crest and the wave trough are arranged at intervals along the width direction, and each first wave zone is higher than each second wave zone.

[0005] The present invention is further configured such that the height difference E between the first wave zone and the second wave zone is 0.1cm-0.25cm.

[0006] The present invention is further configured such that the widths of the first wave zone and the second wave zone are equal.

[0007] The present invention is further configured such that the width A of the crest portion is 0.4cm-0.6cm, the width B of the trough portion is 0.4cm-0.6cm, the width at the connection between the crest portion and the trough portion is smaller than the width of the crest portion, and the width at the connection between the crest portion and the trough portion is smaller than the width of the trough portion.

[0008] The present invention is further configured such that, along the width direction, the distance L between two adjacent crests is 2.8cm-4.2cm, and the distance M between two adjacent troughs is 2.8cm-4.2cm.

[0009] The present invention is further configured such that, in the first wave zone, the wave height H between the wave crest and the wave trough is 3.146cm-4.719cm, and in the second wave zone, the height N between the wave trough and the wave crest is 3.146cm-4.719cm.

[0010] The present invention is further configured such that the polyester-viscose fabric is formed by interlacing 56 warp yarns and 32 weft yarns, the warp point formed by the interlacing of the warp yarns and weft yarns is the first wave zone, and the weft point formed by the interlacing of the warp yarns and weft yarns is the second wave zone.

[0011] The present invention is further configured such that the warp yarn of the polyester-viscose fabric is made of 75D polyester-viscose fiber, and the weft yarn of the polyester-viscose fabric is made of 75D polyester-viscose fiber and 50D polyester-viscose fiber.

[0012] In summary, this utility model has the following beneficial effects:

[0013] By using different thicknesses of warp and weft yarns and weaving them into a wavy curved surface structure, the yarns maintain a curved shape at all times. This allows the yarns to adapt to deformation caused by external forces and quickly return to their original shape. Furthermore, the smooth curves of the fabric reduce surface friction, minimize wrinkles, and increase the fabric's softness and elasticity. The wavy curved surface structure also creates unevenness, further reducing friction and increasing the fabric's breathability. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] This embodiment discloses a polyester-viscose fabric. The fabric is formed by interlacing 56 warp yarns and 32 weft yarns in a composite weave. Warp yarns 1-15 have the same weave as warp yarns 29-43, and warp yarns 16-28 have the same weave as warp yarns 44-56. The 56 warp yarns are threaded through an 8-page heddle frame. (Refer to...) Figure 4 , Figure 5 The weave of warp yarns 1-15 is symmetrical to that of warp yarns 16-28, warp yarns 29-43 are symmetrical to those of warp yarns 16-28, and warp yarns 44-56 are symmetrical to those of warp yarns 29-43. Therefore, the fabric forms the first wave zone 60 and the second wave zone 61 through the interweaving of warp and weft yarns. Because the polyester-viscose fabric is interwoven to form a wave-shaped structure, the wave-shaped bend increases the softness and fluffiness of the fabric, making it more comfortable to use.

[0022] Reference Figure 4 The warp and weft yarns interweave to form the first wave zone 60, and the weft yarns interweave to form the second wave zone 61. In the diagram, black represents the first wave zone 60 and white represents the second wave zone 61. Therefore, the first wave zone 60 and the second wave zone 61 are arranged alternately along the length of the fabric. On each warp yarn, each first wave zone 60 is 4 warp point widths, and each second wave zone 61 is 4 weft point widths. Thus, the widths of the first wave zone 60 and the second wave zone 61 are equal. Furthermore, each first wave zone 60 will not snag or break due to excessively long warp points, and each second wave zone 61 will not snag or break due to excessively long weft points, thereby increasing the fabric's abrasion resistance.

[0023] Reference Figure 4 Because on each warp yarn, each first wave zone 60 has 4 warp points, and each second wave zone 61 has 4 weft points, but the intervals between the 4 warp points and 4 weft points on each warp yarn are different. (Refer to...) Figure 2 , Figure 3Therefore, the fabric is interwoven with warp and weft yarns so that each first wave zone 60 is higher than each second wave zone 61, and the height difference E between the first wave zone 60 and the second wave zone 61 is 0.1cm-0.25cm. Preferably, the height difference E between the first wave zone 60 and the second wave zone 61 is 0.15cm. Therefore, the height difference is increased on the basis of the wave-shaped structure, which increases the air circulation of the fabric, thereby improving the breathability of the fabric and making it more comfortable to use.

[0024] Reference Figure 1 Because the first wave zone 60 and the second wave zone 61 have a wave-shaped structure, both the first wave zone 60 and the second wave zone 61 include a crest 601 and a trough 602. The crests 601 and troughs 602 are arranged alternately along the width direction. Therefore, after the warp and weft yarns interweave, the state of the warp and weft yarns changes from a straight line to a curve, and this curve remains constant in both the first wave zone 60 and the second wave zone 61. Therefore, the fabric...

[0025] Whether it's filament or staple fiber, when subjected to external force, the yarn will be stretched from its curved state to adapt to the deformation caused by the external force. When the external force disappears, the yarn will return to its original shape due to the curved state after interlacing, thus preventing the fabric from wrinkling due to deformation and increasing the fabric's wrinkle resistance. At the same time, because the warp and weft points of the warp and weft yarns in the first wave zone 60 and the second wave zone 61 are connected in a curved shape without interruption, the curved structure fabric formed by the interlacing of the first wave zone 60 and the second wave zone 61 is a smooth curve. Furthermore, the first wave zone 60 is higher than the second wave zone 61, which reduces the friction on the fabric surface and thus also partially reduces the formation of wrinkles. In addition, because the yarn is in a curved state, it can increase the elasticity of the fabric, allowing the fabric to adapt to the stretching of external forces.

[0026] The width A of the crest portion 601 is 0.4cm-0.6cm, preferably 0.5cm. The width B of the trough portion 602 is 0.4cm-0.6cm, preferably 0.5cm. The width at the connection between the crest portion 601 and the trough portion 602 is smaller than the width of the crest portion 601. The width at the connection between the crest portion 601 and the trough portion 602 is smaller than the width of the trough portion 602. This is because in each first wave zone 60 and each second wave zone 61, there are 12 warp yarns between the crest portion 601 and the trough portion 602. Therefore, the wave slope of the first wave zone 60 and the second wave zone 61 is relatively steep. As a result, when the yarns interweave, the degree of bending of the yarns is greater. Therefore, when the fabric is subjected to external force, it can adapt to deformation to a greater extent, thereby reducing the generation of wrinkles and making the fabric more wrinkle-resistant.

[0027] Along the width direction, the distance L between two adjacent wave crests 601 is 2.8cm-4.2cm, preferably 3cm. The distance M between two adjacent wave troughs 602 is 2.8cm-4.2cm, preferably 3cm. Within the first wave zone 60, the wave height H between the wave crests 601 and wave troughs 602 is 3.146cm-4.719cm, preferably 3cm. The wave height H between the troughs 602 is 3.37 cm. Within the second wave zone 61, the height N between the troughs 602 and the crests 601 is 3.146 cm–4.719 cm. Preferably, within the second wave zone 61, the height N between the troughs 602 and the crests 601 is 3.37 cm. This is because the wave height between the crests 601 and the troughs 602 is greater than the distance between two adjacent crests 601, and the wave height between the crests 601 and the troughs 602 is also greater than the distance between two adjacent troughs 602. (Refer to...) Figure 1 Therefore, the wave amplitude formed between the first wave zone 60 and the second wave zone 61 is relatively tight. This is because the warp yarns of the polyester-viscose fabric are made of 75D polyester-viscose fiber, and the weft yarns are made of a mixture of 75D and 50D polyester-viscose fiber. As a result, the warp yarns are tighter where they interweave with the weft yarns, while the weft yarns are looser where they interweave with the 50D yarns. The weft yarns of the fabric are arranged in a 4:4 ratio, which results in a structure where the 75D yarns interweave with each other and the 75D yarns interweave with each other. Combined with the wavy weave structure of the fabric, this allows the fabric to better adapt to deformation, thereby reducing wrinkles and improving the fabric's wrinkle resistance. At the same time, the loose and tight structure increases the fabric's breathability and softness, making it more comfortable to use.
