Description

Technical Field

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

[0002] Polar fleece fabric is generally knitted by large circular knitting machines. After knitting, it is first dyed, and then processed by a variety of complex processes such as napping, combing, shearing, and polarizing. This fabric is fluffy and soft, and has good warmth retention. However, polar fleece fabric uses a knitted fabric structure, with large gaps between coils, and the stability of the fabric is relatively poor.

[0003] For this reason, some polar fleece fabric researchers usually use adhesives to bond woven base fabrics and knitted polar fleece fabrics to improve 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, including 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, which includes a transparent film body, a surface adhesive layer and a bottom adhesive layer, and the surface adhesive layer and the bottom adhesive layer are respectively applied to the opposite sides of the transparent film body. Another example is the Chinese patent document with authorization announcement number CN 213564867 U and name “Antistatic Polar Fleece Fabric”, which discloses an antistatic polar fleece fabric, including 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 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 by an adhesive layer.

[0004] In the above technologies, adhesives are used to make 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. Summary of the invention

[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 integral woven fleece cloth, comprising a fabric body formed by interweaving warp yarns and weft yarns 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.

[0007] As a preferred embodiment of the present application, the weave structure of the first weft yarns and the warp yarns interwoven is a plain weave.

[0008] As a preferred embodiment of the present application, in the connecting portion, the warp yarns are interwoven with the second weft yarns in an up-and-down manner along the weft direction.

[0009] As a preferred embodiment of the present application, the connecting portion protrudes from the front side of the fabric body and forms a jacquard pattern.

[0010] As a preferred embodiment of the present application, the plurality of interwoven connection portions are staggered along the longitudinal direction.

[0011] As a preferred embodiment of the present application, the number of warp yarns corresponding to each connecting portion is 5 or more.

[0013] As a preferred embodiment of the present application, the warp yarn density of the integrated fleece cloth is 615-618 yarns / 10 cm, and the weft yarn density is 656-665 yarns / 10 cm.

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

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

[0016] Compared with 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.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] The present application provides an integral woven fleece cloth, comprising a fabric body formed by interweaving warp yarns and weft yarns 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 the present application has a stable fabric structure, good thermal insulation performance, and meets environmental protection requirements.

[0024] Reference Figure 1 to Figure 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 line part; 100 is the warp yarn, Figure 2 The blank square in the middle indicates; 101 is weft yarn A, i.e. the first weft yarn, Figure 2 The filled lines in the middle represent the squares; 102 is the weft yarn B, i.e. the second weft yarn, such as Figure 2In the middle black filled square, it is shown that it floats on the warp yarn. In the floating line position, the warp yarn and the weft yarn B are not interwoven, that is, in the floating line position 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 fleece fabric described in the embodiment of the present application includes: a warp yarn 100, a first weft yarn 101, and a second weft yarn 102; the first weft yarn 101 and the second weft yarn 102 constitute the weft yarn, and the warp yarn 100 and the weft yarn are interwoven in a woven manner to form a 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, and the second weft yarn 102 and the warp yarn 100 form a plurality of mutually interwoven connecting parts 122, and form a plurality of non-interwoven floating parts 123, the middle parts of the plurality of floating parts 123 are disconnected to form fluff 121, and the plurality of fluff 121 constitutes the terry layer 12. In addition, the warp yarn 100 and the first weft yarn 101 are both made of polyester-spandex air-spun yarn, and the second weft yarn 102 is made of polyester low-elastic yarn.

[0026] The warp yarn is the yarn that extends along the length of the loom and along the length of the fabric; the weft yarn is the yarn that runs along the weft direction (width direction) of the fabric, and the direction of the fabric width is the weft direction. Woven fabrics are woven into warp and weft fabrics by throwing the shuttle, that is, the two systems of yarns perpendicular to each other are interwoven on the loom according to a certain rule. The overlapping points of the warp and weft yarns due to mutual sinking and floating are called weave points; its basic fabric structure includes plain weave, twill weave, satin weave, etc. Among them, the weave formed by the warp and weft yarns interweaving one up and one down (one floating and one sinking) is called plain weave; the weave with warp weave points (or weft weave points) continuously forming oblique lines is called twill weave. Individual, discontinuous warp weave points (or weft weave points) are regularly and evenly distributed in the weave cycle, and such a weave is called satin weave; the individual weave points of the satin weave are covered by the floating long lines of the other system of yarns on both sides, and the surface of the fabric presents warp floating long lines (or weft floating long lines).

[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 connection part 122 described in the preferred embodiment of the present application, multiple warp yarns 100 are interwoven with the second weft yarn 102 in an up-down manner along the weft direction (that is, in the connection part 122, the second weft yarn 102 is sequentially passed from the upper part of one warp yarn 100, passed into the lower part of the next warp yarn 100, and then passed to the upper part of the next warp yarn 100), so that the connection part 122 is more firmly combined with the fabric, ensuring that the pile 121 of the terry layer 12 is not easy to fall off. The "upper" and "lower" in the embodiment of the present application are described in terms of the orientation when the fabric body 10 is placed flat on a horizontal plane.

[0029] Furthermore, the connection part 122 is protruding 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 reverse side. As a preferred embodiment of the present application, multiple connection parts 122 are staggered along the warp direction to form a small texture pattern.

[0030] As a preferred embodiment of the present application, the number of warp yarns 100 corresponding to one floating portion 123 is 9 or more, and in some embodiments, the number of warp yarns 100 corresponding to one connecting portion 122 is 5 or more; in a specific embodiment, the number of warp yarns 100 corresponding to one connecting portion 122 is 5, 2 of which are located above the weft yarn B102, and 3 of which are located below the weft yarn B102.

[0031] In a preferred embodiment of the present application, 615-618 warp yarns 100, further 616 warp yarns 100 are arranged every 10 cm along the weft direction; 656-665 weft yarns, further 660 weft yarns are arranged 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 that of weft yarn B is usually 2:1), which can make the fabric structure compact.

[0032] Specifically, the floating line 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 shaking treatments, and the surface fibers of the fabric are hooked out, straightened and cut flat by a machine. The resulting fabric is thick and smooth while having a good warmth-keeping effect. Usually, thinner fabrics are not suitable for fleece grabbing, which will affect the effect of the front side 11. Fabrics with great elasticity are also not suitable for fleece grabbing, and cutting spandex will destroy the elasticity. In the embodiment of the present application, spandex is woven into the front side 11. In some embodiments, the average length of the fluff in the terry layer 12 is 0.1-0.6cm, and the length of the floating line portion 123 is 0.15-1cm; the fabric weight is 250-260g / 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: outer yarn and spandex, wherein spandex is the core yarn and the outer yarn is wrapped outside; the outer yarn of polyester spandex air core-spun yarn is polyester, and the yarn is twisted by the jet vortex generated by compressed air and then wrapped to form the yarn, which can be referred to as polyester spandex air core-spun yarn, polyester spandex air-spun yarn, etc. As a preferred embodiment of the present application, the polyester spandex air core-spun yarn uses 30-50D spandex as the core yarn and 70-80D / 72F polyester low-elastic yarn as the outer yarn.

[0034] Further preferably, the polyester-spandex air-covered yarn is an air-covered yarn formed by 75D / 72F polyester low-elastic yarn coated with 40D spandex; specifically, the polyester low-elastic yarn (its elastic recovery rate under the standard method is usually 85% to 95%) is a semi-bright 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 a 300D / 576F polyester low-elastic yarn. In the present application, D is referred to as the denier number 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-elastic 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 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 obtains the one-piece fleece cloth by fleecing, etc., wherein a long floating line portion is left during weaving. The embodiment of the present application can form the fleece by conventional fleece drawing, shearing and polarizing, and the machines involved in the fleece drawing, shearing and polarizing 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.
