Abstract
Description
Technical Field
[0001] This disclosure relates to the field of textile technology, and in particular to a pure cashmere tweed. Background Technology
[0002] Cashmere fibers are fine and soft, and pure cashmere tweed made from it is soft to the touch and has excellent warmth retention, making it suitable for making outerwear for autumn and winter. However, because the fabric can become stuffy and sweaty when in contact with the body for extended periods, the sweat vapor can seep into the cashmere surface, causing it to stick together, reducing its fluffiness, and thus decreasing its warmth retention.
[0003] Therefore, the technical problem that urgently needs to be solved by those skilled in the art is how to improve the breathability of pure cashmere tweed while ensuring its warmth. Utility Model Content
[0004] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide a pure cashmere tweed.
[0005] According to a first aspect of this disclosure, a pure cashmere tweed is provided, wherein the yarn structure of the pure cashmere tweed is 8 heddles, wherein the weaving point of the first warp is 2 purl 4 purl 2 purl, the weaving point of the second warp is 1 purl 1 purl 1 purl 2 purl 1 purl 1 purl 1 purl 1 purl 2 purl 1 purl 1 purl 1 purl, the weaving point of the third warp is 4 purl 4 purl, the weaving point of the fourth warp is 1 purl 2 purl 1 purl 1 purl 2 purl 1 purl 1 purl 1 purl 1 purl 2 purl 1 purl, the weaving point of the fifth warp is 2 purl 4 purl 2 purl, the weaving point of the sixth warp is 1 purl 1 purl 1 purl 1 purl 2 purl 1 ...
[0006] The weave pattern of the first warp is 2 up, 4 down, 2 up; the weave pattern of the second warp is 1 up, 2 down, 1 up, 1 down, 2 up, 1 down; the weave pattern of the third warp is 2 up, 4 down, 2 up; the weave pattern of the fourth warp is 1 down, 2 up, 1 down, 1 up, 2 down, 1 up; the weave pattern of the fifth warp is 2 down, 4 up, 2 down; the weave pattern of the sixth warp is 1 down, 2 up, 1 down, 1 up, 2 down, 1 up; the weave pattern of the seventh warp is 2 up, 4 down, 2 up; and the weave pattern of the eighth warp is 1 up, 2 down, 1 up, 1 down, 2 up, 1 down.
[0007] In one embodiment of this disclosure, in the yarn structure of the pure cashmere tweed, the first, third, fifth, and seventh warp and weft yarns are made of coarse cashmere yarn, and the second, fourth, sixth, and eighth warp and weft yarns are made of worsted cashmere yarn.
[0008] In one embodiment of this disclosure, the coarse cashmere yarn is made of pure cashmere, with an average fineness of 16.1-16.5 μm and an average fiber length of 26-28 mm.
[0009] The worsted cashmere yarn is made of pure cashmere, with an average fiber fineness of 16.1-16.5 μm and an average fiber length of 34-36 mm.
[0010] In one embodiment of this disclosure, the coarse cashmere yarn has a yarn count of 20 / 2NM-24 / 2NM, a single yarn twist coefficient of 115-120, and a ply yarn twist coefficient of 120-125; the worsted cashmere yarn has a yarn count of 84 / 2NM-90 / 2NM, a single yarn twist coefficient of 110-115, and a ply yarn twist coefficient of 125-130.
[0011] In one embodiment of this disclosure, the warp density is 220-232 yarns / 10cm and the weft density is 196-208 yarns / 10cm.
[0012] In one embodiment of this disclosure, the width of the pure cashmere tweed is 150-152 cm.
[0013] In one embodiment of this disclosure, the pilling level of the pure cashmere tweed is ≥3;
[0014] The longitudinal dimensional variation rate of the pure cashmere tweed is ≥-3; the transverse dimensional variation rate is ≥-3.
[0015] The longitudinal tear strength of the pure cashmere tweed is ≥10N; the transverse tear strength is ≥10N.
[0016] The longitudinal breaking strength of the pure cashmere tweed is ≥147N; the transverse breaking strength is ≥147N.
[0017] The longitudinal seam allowance of the pure cashmere tweed is ≤6mm; the transverse seam allowance is ≤6mm.
[0018] The weight per square meter of the pure cashmere tweed is 275-280g / ㎡.
[0019] One beneficial effect of the disclosed pure cashmere tweed is that the yarn structure unit of the pure cashmere tweed has long floats and fewer interlacing times. Yarns adjacent to the long floats are gathered together under the action of the long floats. Warp yarns located at the weft long float positions of the yarn structure unit move closer together, and weft yarns located at the weft long float positions move closer together, increasing the horizontal and vertical gaps between the yarns. This creates numerous breathable gaps on the surface of the pure cashmere tweed, thus giving it excellent breathability and reducing the stuffiness of the garment. Furthermore, by shifting the weaving points, different fabric textures can be created, allowing garments to be made to suit the preferences of different customers. Attached Figure Description

[0025] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values of the components and steps set forth in these embodiments do not limit the scope of the present disclosure.
[0026] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this disclosure or its application or use.

[0028] In all the examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.
[0029] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.
[0030] In this article, terms such as "up," "down," "front," "back," "left," and "right" are used only to indicate the relative positional relationship between related parts, rather than to define the absolute position of these related parts.
[0031] In this article, "first," "second," etc., are used only to distinguish one another, and not to indicate degree of importance, order, or prerequisite for each other.
[0032] In this document, terms such as “equal” and “same” are not strict mathematical and / or geometric limitations, but also include errors that are understandable to those skilled in the art and permissible in manufacturing or use.
[0033] Weave point: In fabric weave, the weave point refers to the intersection of warp and weft yarns, and is divided into warp weave points and weft weave points. A warp weave point is the point where the warp yarn is above the weft yarn, while a weft weave point is the point where the weft yarn is above the warp yarn.
[0034] Weave point count: Weave point count refers to the number of weave points in the longitudinal (or transverse) interval between corresponding warp and weft weave points on two adjacent yarns in the same system.
[0035] Float: In a fabric structure, if a warp yarn has consecutive warp weft points, then that warp yarn will continuously float above several weft yarns. Similarly, if a weft yarn has consecutive weft weft points, then that weft yarn will continuously float above several warp yarns. The length of this continuous floating length on another yarn system is called the float length.
[0036] Figures 1-4 In the diagram, A represents coarse cashmere yarn, B represents fine cashmere yarn, X represents the weft weft point formed above the warp yarn, and the numbers 1-8 indicate which warp or weft yarn it is.
[0037] This disclosure provides a pure cashmere tweed. For ease of understanding, please refer to the following: Figures 1-4 The specific structure of the pure cashmere tweed disclosed herein will be described in detail with reference to the embodiments.
[0038] Example 1:
[0039] Reference Figure 1 , Figure 2 The yarn structure of pure cashmere tweed is 8 heddles. The weave pattern of the first warp is 2 purl 4 purl 2 purl, the second warp is 1 purl 1 purl 1 purl 2 purl 1 purl 1 purl 1 purl 1 purl 1 purl 1 purl 1 purl 1 purl 1 purl 1 purl 1 purl 1 purl 1 purl 4 purl, the fourth warp is 1 purl 2 purl 1 ...
[0040] Specifically, in Example 1, the long floats in the first, third, fifth, and seventh warp yarns of the pure cashmere tweed are slanted upwards and to the right. The pure cashmere tweed in Example 1 has long floats and fewer interlacing times. The yarns adjacent to the long floats are gathered together under the influence of the long floats, resulting in larger gaps between the yarns and giving the finished garments excellent breathability. Furthermore, the different weave textures create fabrics with varying styles, allowing garments to suit different customer preferences.
[0041] like Figure 2In the process, the third and fourth weft yarns converge towards the first and second weft yarns under the influence of the third warp yarn, while the third and fourth weft yarns converge towards the fifth and sixth weft yarns under the influence of the fifth warp yarn, forming slanted yarn gaps. Similarly, the surface of pure cashmere tweed has numerous slanted, breathable gaps, giving it excellent breathability and reducing the stuffiness of the garment.
[0042] In one embodiment, in the yarn structure of the pure cashmere tweed, the first, third, fifth, and seventh warp and weft yarns are made of coarse cashmere yarn, while the second, fourth, sixth, and eighth warp and weft yarns are made of worsted cashmere yarn.
[0043] Specifically, the woolen cashmere yarn and the worsted cashmere yarn are evenly arranged in a 1:1 ratio, with the woolen cashmere yarn being nearly four times thicker than the worsted cashmere yarn. In the woven fabric, the woolen cashmere yarn accounts for 80% of the visible material, and the overall style of the fabric is reflected by the woolen cashmere yarn. The fabric surface has a rough and rugged style.
[0044] Coarse cashmere yarn uses shorter cashmere fibers. If a pure coarse cashmere tweed is made entirely from coarse cashmere yarn, the low yarn count results in a heavy fabric with high yarn twist, making it difficult to achieve a nap during the fulling process, and prone to creases. Coarse cashmere tweed also suffers from difficult-to-control issues like seam tearing and pilling. Therefore, adding a portion of worsted cashmere yarn makes these physical properties easier to control, improving the fabric's feel and overall physical properties, significantly reducing its weight per square meter, and making it lighter and thinner.
[0045] If fine cashmere yarn is used to make fine pure cashmere tweed, it requires fine and long cashmere as raw material, which is difficult to produce and has high costs, resulting in higher garment prices. Therefore, adding coarse cashmere yarn reduces raw material and processing costs, resulting in lower garment prices.
[0046] Coarse cashmere yarn is coarse in itself and is set on a weave with long floats, making it more prominent in pure cashmere tweed. Worsted cashmere yarn is fine in itself and is set on a weave with short floats, making it less likely to show in pure cashmere tweed, giving the tweed a rugged look.
[0047] In one embodiment, the coarse cashmere yarn is made of pure cashmere with an average fiber fineness of 16.1-16.5 μm and an average fiber length of 26-28 mm; the fine cashmere yarn is made of pure cashmere with an average fiber fineness of 16.1-16.5 μm and an average fiber length of 34-36 mm.
[0048] Specifically, both woolen and worsted cashmere yarns use 100% pure cashmere as raw material. Woolen cashmere yarn uses lower grade cashmere, has a shorter spinning process, and lower processing and raw material costs. Worsted cashmere yarn uses higher grade cashmere, has a longer spinning process, and is easier to full to create a napped surface, resulting in a better-feeling finished product.
[0049] In one embodiment, the count of the coarse cashmere yarn is 20 / 2NM-24 / 2NM, the twist coefficient of the single yarn is 115-120, and the twist coefficient of the ply yarn is 120-125; the count of the worsted cashmere yarn is 84 / 2NM-90 / 2NM, the twist coefficient of the single yarn is 110-115, and the twist coefficient of the ply yarn is 125-130.
[0050] Specifically, the woolen cashmere yarn has a count of 22 / 2 NM and a twist coefficient of [115-120]*[120-125]; the worsted cashmere yarn has a count of 84 / 2 NM and a twist coefficient of [110-115]*[125-130].
[0051] In one embodiment, the warp density is 220-232 yarns / 10cm and the weft density is 196-208 yarns / 10cm.
[0052] Specifically, the warp density is 226 threads / 10cm, and the weft density is 202 threads / 10cm. Based on experience, the actual warp density is determined to be 184*194 threads / 10cm. The weaving shrinkage is 5.0% in length and 8.6% in width, while the finishing shrinkage is 1.4% in length and 11.1% in width. Therefore, the total warp threads used on the loom are 3422, and the reed number is 46#.
[0053] In one embodiment, the width of the pure cashmere tweed is 150-152cm.
[0054] Specifically, the width of pure cashmere tweed is 150cm.
[0055] In one embodiment, the pilling level of the pure cashmere tweed is ≥3; the longitudinal dimensional change rate of the pure cashmere tweed is ≥-3; the transverse dimensional change rate is ≥-3; the longitudinal tear strength of the pure cashmere tweed is ≥10N; the transverse tear strength is ≥10N; the longitudinal breaking strength of the pure cashmere tweed is ≥147N; the transverse breaking strength is ≥147N; the longitudinal seam allowance of the pure cashmere tweed is ≤6mm; the transverse seam allowance is ≤6mm; and the weight per square meter of the pure cashmere tweed is 275-280g / ㎡.
[0056] Specifically, the pilling grade of pure cashmere tweed is 3; the longitudinal dimensional change rate of pure cashmere tweed is -2.8%; the transverse dimensional change rate is -1.1%; the longitudinal tear strength of pure cashmere tweed is 31.3N; the transverse tear strength is 31.6N; the longitudinal breaking strength of pure cashmere tweed is 191N; the transverse breaking strength is 229N; the longitudinal seam allowance of pure cashmere tweed is 5.4mm; the transverse seam allowance is 5.8mm; and the weight per square meter of pure cashmere tweed is 278.9g / ㎡.
[0057] Table 1 shows the testing indicators for the finished pure cashmere tweed fabric disclosed in this paper.
[0058]
[0059] Table 1
[0060] As shown in Table 1, the pure cashmere tweed disclosed herein meets national standards in terms of pilling grade, tear strength, and breaking strength.
[0061] Example 2:
[0062] Reference Figure 3 , Figure 4 The weaving point of the first warp is 2 up, 4 down, 2 up; the weaving point of the second warp is 1 up, 2 down, 1 up, 1 down, 2 up, 1 down; the weaving point of the third warp is 2 up, 4 down, 2 up; the weaving point of the fourth warp is 1 down, 2 up, 1 down, 1 up, 2 down, 1 up; the weaving point of the fifth warp is 2 down, 4 up, 2 down; the weaving point of the sixth warp is 1 down, 2 up, 1 down, 1 up, 2 down, 1 up; the weaving point of the seventh warp is 2 up, 4 down, 2 up; and the weaving point of the eighth warp is 1 up, 2 down, 1 up, 1 down, 2 up, 1 down.
[0063] Specifically, the pure cashmere tweed in Example 2 differs from that in Example 1 in terms of the number of weave points. In Example 2, the pure cashmere tweed uses a displacement weave point, with long floats in the first, third, fifth, and seventh warp yarns arranged side-by-side. Both Example 1 and Example 2 have long floats and fewer interlacing times. The yarns adjacent to the long floats are gathered together under their influence, resulting in larger gaps between the yarns and providing excellent breathability in the finished garments. Furthermore, the weave texture differs from that in Example 1, creating fabrics with different styles to suit customers with varying preferences.
[0064] like Figure 4In the fabric, the third, fourth, fifth, and sixth weft yarns converge under the action of the fifth and seventh warp yarns; the first and second weft yarns, and the seventh and eighth weft yarns converge under the action of the first and third warp yarns; the fourth, fifth, sixth, and seventh warp yarns converge under the action of the first and seventh weft yarns; and the first, second, and third warp yarns converge under the action of the third and fifth weft yarns, creating relatively large gaps between the yarns. The third and fourth warp yarns are further apart, as are the second and third weft yarns. These four yarns create significant air gaps. Similarly, the surface of pure cashmere tweed exhibits numerous parallel air gaps, giving it excellent breathability and reducing the stuffiness of the garment.
[0065] In one embodiment, in the yarn structure of the pure cashmere tweed, the first, third, fifth, and seventh warp and weft yarns are made of coarse cashmere yarn, while the second, fourth, sixth, and eighth warp and weft yarns are made of worsted cashmere yarn.
[0066] Specifically, the woolen cashmere yarn and the worsted cashmere yarn are evenly arranged in a 1:1 ratio, with the woolen cashmere yarn being nearly four times thicker than the worsted cashmere yarn. In the woven fabric, the woolen cashmere yarn accounts for 80% of the visible material, and the overall style of the fabric is reflected by the woolen cashmere yarn. The fabric surface has a rough and rugged style.
[0067] Coarse cashmere yarn uses shorter cashmere fibers. If a pure coarse cashmere tweed is made entirely from coarse cashmere yarn, the low yarn count results in a heavy fabric with high yarn twist, making it difficult to achieve a nap during the fulling process, and prone to creases. Coarse cashmere tweed also suffers from difficult-to-control issues like seam tearing and pilling. Therefore, adding a portion of worsted cashmere yarn makes these physical properties easier to control, improving the fabric's feel and overall physical properties, significantly reducing its weight per square meter, and making it lighter and thinner.
[0068] If fine cashmere yarn is used to make fine pure cashmere tweed, it requires fine and long cashmere as raw material, which is difficult to produce and has high costs, resulting in higher garment prices. Therefore, adding coarse cashmere yarn reduces raw material and processing costs, resulting in lower garment prices.
[0069] Coarse cashmere yarn is coarse in itself and is set on a weave with long floats, making it more prominent in pure cashmere tweed. Worsted cashmere yarn is fine in itself and is set on a weave with short floats, making it less likely to show in pure cashmere tweed, giving the tweed a rugged look.
[0070] In one embodiment, the coarse cashmere yarn is made of pure cashmere with an average fiber fineness of 16.1-16.5 μm and an average fiber length of 26-28 mm; the fine cashmere yarn is made of pure cashmere with an average fiber fineness of 16.1-16.5 μm and an average fiber length of 34-36 mm.
[0071] Specifically, both woolen and worsted cashmere yarns use 100% pure cashmere as raw material. Woolen cashmere yarn uses lower grade cashmere, has a shorter spinning process, and lower processing and raw material costs. Worsted cashmere yarn uses higher grade cashmere, has a longer spinning process, and is easier to full to create a napped surface, resulting in a better-feeling finished product.
[0072] In one embodiment, the count of the coarse cashmere yarn is 20 / 2NM-24 / 2NM, the twist coefficient of the single yarn is 115-120, and the twist coefficient of the ply yarn is 120-125; the count of the worsted cashmere yarn is 84 / 2NM-90 / 2NM, the twist coefficient of the single yarn is 110-115, and the twist coefficient of the ply yarn is 125-130.
[0073] Specifically, the woolen cashmere yarn has a count of 22 / 2 NM and a twist coefficient of [115-120]*[120-125]; the worsted cashmere yarn has a count of 84 / 2 NM and a twist coefficient of [110-115]*[125-130].
[0074] In one embodiment, the warp density is 220-232 yarns / 10cm and the weft density is 196-208 yarns / 10cm.
[0075] Specifically, the warp density is 226 threads / 10cm, and the weft density is 202 threads / 10cm. Based on experience, the actual warp density is determined to be 184*194 threads / 10cm. The weaving shrinkage is 5.0% in length and 8.6% in width, while the finishing shrinkage is 1.4% in length and 11.1% in width. Therefore, the total warp threads used on the loom are 3422, and the reed number is 46#.
[0076] In one embodiment, the width of the pure cashmere tweed is 150-152cm.
[0077] Specifically, the width of pure cashmere tweed is 150cm.
[0078] In one embodiment, the pilling level of the pure cashmere tweed is ≥3; the longitudinal dimensional change rate of the pure cashmere tweed is ≥-3; the transverse dimensional change rate is ≥-3; the longitudinal tear strength of the pure cashmere tweed is ≥10N; the transverse tear strength is ≥10N; the longitudinal breaking strength of the pure cashmere tweed is ≥147N; the transverse breaking strength is ≥147N; the longitudinal seam allowance of the pure cashmere tweed is ≤6mm; the transverse seam allowance is ≤6mm; and the weight per square meter of the pure cashmere tweed is 275-280g / ㎡.
[0079] Specifically, the pilling grade of pure cashmere tweed is 3; the longitudinal dimensional change rate of pure cashmere tweed is -2.8%; the transverse dimensional change rate is -1.1%; the longitudinal tear strength of pure cashmere tweed is 31.3N; the transverse tear strength is 31.6N; the longitudinal breaking strength of pure cashmere tweed is 191N; the transverse breaking strength is 229N; the longitudinal seam allowance of pure cashmere tweed is 5.4mm; the transverse seam allowance is 5.8mm; and the weight per square meter of pure cashmere tweed is 278.9g / ㎡.
[0080] The pure cashmere tweed of this embodiment, as shown in Table 1, meets national standards in terms of pilling level, tear strength, and breaking strength.
