Description

Technical Field

[0001] The present application belongs to the field of textile fabrics, and in particular relates to an integrally woven fleece fabric. Background Art

[0002] Polar fleece is typically knitted on large circular knitting machines. After being woven, the fabric undergoes dyeing, followed by a complex process involving napping, carding, shearing, and polarizing. This fabric is fluffy, soft, and offers excellent warmth retention. However, polar fleece's knitted structure results in large gaps between the loops, making it relatively unstable.

[0003] To this end, some polar fleece fabric researchers usually use adhesives to bond the woven base fabric and the knitted polar fleece fabric to improve the fabric stability. For example, in the Chinese patent document entitled "A Knitted Denim Composite Fabric" with the authorization announcement number CN 204598683U, a knitted denim composite fabric is disclosed, which includes a knitted denim fabric layer, a transparent film adhesive layer and a polar fleece knitted fabric layer. The transparent film adhesive layer is bonded to the knitted denim fabric layer on one side and to the polar fleece knitted fabric layer on the other side. The transparent film adhesive layer is also called a transparent film layer. The transparent film layer includes a transparent film body, a surface adhesive layer and a base adhesive layer. The surface adhesive layer and the base adhesive layer are respectively applied to the opposite sides of the transparent film body. Another example is the Chinese patent document with authorization publication number CN 213564867 U and titled “Antistatic Polar Fleece Fabric”, which discloses an antistatic polar fleece fabric comprising a base fabric layer and a polar fleece fabric layer bonded to one surface of the base fabric layer, wherein the base fabric layer is woven from elastic fibers, and the polar fleece fabric layer is woven from polyester fibers and veil fibers, wherein the polyester fibers are arranged in a loop shape and wrapped around the veil fibers, and the veil fibers are formed by twisting a plurality of nylon yarns and at least one conductive yarn, and the base fabric layer is bonded to the polar fleece fabric layer through an adhesive layer.

[0004] In the above technologies, adhesives are used to produce polar fleece fabrics. On the one hand, the adhesives may be difficult to meet environmental protection requirements, and on the other hand, there is a risk of delamination, which needs further improvement. Utility Model Content

[0005] In view of the above problems, the purpose of the present application is to provide an integrally woven fleece fabric, which has a stable structure, not only has good thermal insulation performance, but also meets environmental protection requirements.

[0006] The present application provides an integrated woven fleece fabric, comprising a fabric body formed by weft yarns and warp yarns woven in a shuttle-woven manner, the weft yarns comprising a first weft yarn and a second weft yarn, the first weft yarn being interwoven with the warp yarns to form a non-fluff surface of the fabric body, the second weft yarn and the warp yarn forming a plurality of mutually interwoven connecting portions and a plurality of non-interwoven floating line portions, the middle portions of the plurality of non-interwoven floating line portions being disconnected to form a terry layer, the warp yarn and the first weft yarn both being made of polyester spandex air core-spun yarn, and the second weft yarn being made of polyester low-elastic yarn.

[0014] As a preferred embodiment of the present application, the polyester spandex air core-spun yarn comprises 30-50D spandex as the core yarn and 70-80D / 72F polyester low-elastic yarn as the outer covering yarn.

[0015] As a preferred embodiment of the present application, the second weft yarn is 300D / 576F polyester low-stretch yarn.

[0016] Compared to knitted fabrics, in the technical solution of the present application, the first weft yarn and the warp yarn are interwoven in a woven manner, and the structure is relatively stable; the warp yarn and the first weft yarn are both made of polyester spandex air core yarn, which not only gives the fabric a certain elasticity, but also increases the softness and warmth retention of the fabric.

[0021] The following will be combined with the drawings and other figures in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0022] The present application provides an integrated woven fleece fabric, comprising a fabric body formed by weft yarns and warp yarns woven in a shuttle-woven manner, the weft yarns comprising a first weft yarn and a second weft yarn, the first weft yarn being interwoven with the warp yarns to form a non-fluff surface of the fabric body, the second weft yarn and the warp yarn forming a plurality of mutually interwoven connecting portions and a plurality of non-interwoven floating line portions, the middle portions of the plurality of non-interwoven floating line portions being disconnected to form a terry layer, the warp yarn and the first weft yarn both being made of polyester spandex air core-spun yarn, and the second weft yarn being made of polyester low-elastic yarn.

[0023] The one-piece woven fleece fabric provided in this application has a stable fabric structure, good thermal insulation performance, and meets environmental protection requirements.

[0024] Reference Figures 1 to 2 , where 10 is the fabric body; 11 is the front side, i.e. the non-pile surface; 12 is the terry layer; 121 is the pile; 122 is the connecting part; 123 is the floating part; 100 is the warp yarn, Figure 2 The blank square in the middle represents: 101 is weft yarn A, i.e. the first weft yarn, Figure 2 The filled lines in the middle represent the grid; 102 is the weft yarn B, i.e. the second weft yarn, such as Figure 2In the floating part, the warp yarn and the weft yarn B are not interwoven, that is, in the floating part 123, the weft yarn B is below the warp yarn and is blocked by the warp yarn, so only the warp yarn represented by the white square can be seen.

[0025] The one-piece woven fleece fabric described in this embodiment includes warp yarns 100, a first weft yarn 101, and a second weft yarn 102. The first weft yarn 101 and the second weft yarn 102 form the weft yarns, and the warp yarns 100 and the weft yarns are interwoven in a woven manner to form the fabric body 10. The first weft yarn 101 and the warp yarn 100 are interwoven to form the front surface 11 of the fabric body 10. The second weft yarn 102 and the warp yarn 100 form multiple interwoven connecting portions 122 and multiple non-interwoven floating portions 123. The multiple floating portions 123 are disconnected at the center to form piles 121. The multiple piles 121 constitute the terry layer 12. Furthermore, the warp yarn 100 and the first weft yarn 101 are both polyester-spandex air-spun yarns, while the second weft yarn 102 is polyester low-stretch yarn.

[0026] The warp yarns are the yarns that run along the length of the loom, along the fabric's width; the weft yarns are the yarns that run along the weft (width) of the fabric, with the width of the fabric being the weft. Woven fabrics are woven using a shuttle method, interlacing yarns in the warp and weft directions. This means that two perpendicular yarn systems, warp and weft, are interwoven on the loom in a regular pattern. The points where the warp and weft yarns overlap due to their floating and sinking behavior are called weave points. Basic weave structures include plain weave, twill weave, and satin weave. Plain weave is a weave in which warp and weft yarns alternately interweave (one floating, one sinking) and interweave (one floating, one sinking). Twill weave is a weave in which warp (or weft) points are continuously arranged in diagonal lines. Satin weave is a weave in which individual, discontinuous warp (or weft) points are evenly and regularly distributed within the weave loop. In satin weave, individual weave points are obscured by floats from the other yarn system on either side, resulting in warp (or weft) floats appearing throughout the fabric surface.

[0027] In some embodiments of the present application, the first weft yarn 101 and the warp yarn 100 are interwoven in a plain weave. The first weft yarn 101 and the warp yarn 100 are tightly interwoven, have a strong texture, and are not easily worn.

[0028] In the preferred embodiment of the present application, the connecting portion 122 of the present application is interwoven with the second weft yarn 102 in an over-under manner along the weft direction (i.e., in the connecting portion 122, the second weft yarn 102 sequentially passes from the top of one warp yarn 100, passes under the bottom of the next warp yarn 100, and then passes to the top of the next warp yarn 100). This allows the connecting portion 122 to be more firmly integrated into the fabric, ensuring that the pile 121 of the terry layer 12 is not easily detached. The "top" and "bottom" in the present embodiment are described with the fabric body 10 lying flat on a horizontal surface.

[0029] Furthermore, the connecting portion 122 protrudes from the front side 11 of the fabric body 10 and forms a jacquard pattern; the front side 11 is the non-pile surface of the fabric body 10, and the other surface with the pile is the back side. As a preferred embodiment of the present application, multiple connecting portions 122 are staggered along the warp direction to form a fine texture pattern.

[0030] As a preferred embodiment of the present invention, one floating portion 123 corresponds to nine or more warp yarns 100, and in some embodiments, the corresponding warp yarns 100 may be nine. As a preferred embodiment of the present invention, one connecting portion 122 corresponds to five or more warp yarns 100; in a specific embodiment, the corresponding warp yarns 100 are five, two of which are located above the weft yarn B102 and three of which are located below the weft yarn B102.

[0031] In a preferred embodiment of the present application, 615-618 warp yarns 100, and further 616 warp yarns 100 are laid out every 10 cm along the weft direction; 656-665 weft yarns, and further 660 weft yarns are laid out every 10 cm along the warp direction (this is the sum of the number of weft yarns in the two sets, and the ratio of the number of weft yarns A to weft yarns B is usually 2:1), which can make the fabric structure compact.

[0032] Specifically, the floating portion 123 can be processed using existing technology, and the woven fabric is finished with raising oil to make the fabric fluffy, soft, and easy to process; then it is subjected to napping, shearing, and polarizing treatments, and the surface fibers of the fabric are hooked out, straightened, and flattened by a machine. The resulting fabric is thick and smooth while having a good warmth-keeping effect. Generally, thinner fabrics are not suitable for napping, which will affect the effect of the front 11. Fabrics with great elasticity are also not suitable for napping, and cutting spandex will destroy the elasticity. In the embodiment of the present application, spandex is woven into the front 11. In some embodiments, the average length of the fluff in the terry layer 12 is 0.1-0.6 cm, and the length of the floating portion 123 is 0.15-1 cm; the fabric weight is 250-260 g / m 2 , the thickness of the fabric is 0.3-1.5cm. In a further embodiment, the length of the pile can be 0.15cm, the length of the floating line can be 0.1cm, the thickness of the fabric can be 0.3cm, and the weight of the fabric is 250g / m2 .

[0033] Spandex core-spun yarn is generally composed of two parts: the spandex core yarn and the outer covering yarn. The spandex is the core yarn, and the outer covering yarn is the outer covering yarn. Polyester spandex air-spun yarn is made of polyester outer covering yarn. The yarn is spun by applying false twist to the yarn strips using the jet vortex generated by compressed air, and can be simply referred to as polyester-spandex air-spun yarn, polyester-spandex air-spun yarn, etc. As a preferred embodiment of this application, the polyester spandex air-spun yarn is made of 30-50D spandex as the core yarn and 70-80D / 72F polyester low-stretch yarn as the outer covering yarn.

[0034] Further preferably, the polyester-spandex air-covered yarn is an air-covered yarn formed by 75D / 72F polyester low-stretch yarn coated with 40D spandex; specifically, the polyester low-stretch yarn (its elastic recovery rate under the standard method is generally 85% to 95%) is a semi-gloss yarn, which is not easy to fade and is more wear-resistant. As a preferred embodiment of the present application, the weft yarn B102 is 300D / 576F polyester low-stretch yarn. In this application, D is referred to as the denier in the industry, which refers to the weight of 9000 meters of yarn (in grams); F refers to the number of microfibers in a yarn. In the embodiment of the present application, the weft yarn B102 uses a high F-number polyester low-stretch yarn, which can ensure the softness and comfort of the fluff. The D value and F value of the weft yarn A101 and the warp yarn 100 are coordinated and adapted to each other, making the fabric soft and delicate, and having good skin-friendliness.

[0035] The embodiment of the present application mainly weaves two sets of weft yarns and warp yarns, and then processes the fleece to obtain the one-piece fleece fabric, wherein a long floating portion is left during weaving. The embodiment of the present application can form the fleece through conventional fleece-pulling, shearing, and polarizing processes, and the machines involved in the fleece-pulling, shearing, and polarizing processes are conventional equipment in the textile field.

[0036] The woven structure of the one-piece fleece fabric described in the embodiment of the present application is relatively stable, and the fabric has good softness and thermal insulation performance; the terry layer is interwoven on the fabric body through the connecting part, is not easy to fall apart, and is more environmentally friendly.

[0037] In order to better illustrate the present application, the following examples are further illustrated. Unless otherwise specified, the various reagents and raw materials used in this application are all commercially available products or products that can be prepared by recognized methods. Unless otherwise specified, the ratios involved are all weight ratios.
