Abstract
Description
Technical Field
[0001] This invention relates to the field of woven fabric technology, and in particular to a breathable Oxford cloth and its preparation method. Background Technology
[0002] Oxford cloth originated from Oxford spinning, and its typical woven structure is a weft-weight plain weave. To meet industrial needs, modern Oxford cloth, in addition to cotton yarn, widely uses polyester, nylon and other chemical fiber filaments for weaving to improve the mechanical properties of the fabric.
[0003] Existing pet products, such as pet sleeping mats and pet carrying bags, can use Oxford cloth as the outer fabric to make the products less prone to damage when scratched by pets.
[0004] However, in practical applications, existing Oxford cloth is coated with a stain-resistant coating to prevent pet dirt from penetrating the padding underneath. But this coating significantly reduces the breathability of the outer fabric to the pet's paws. Summary of the Invention
[0005] To address the aforementioned technical problems, this invention provides a breathable Oxford cloth and its preparation method.
[0006] This application provides a breathable Oxford cloth, comprising: The fabric is woven from yarns made of polyamide material; A coating is applied to the surface of the fabric. The fabric includes a weft-weighted plain weave and a breathable weave. The weft-weighted plain weave extends along the weft direction and has weft yarns interwoven within the breathable weave. The breathable weave includes N sets of skeins arranged along the warp direction. The N sets of skeins are twisted together along the warp direction, where N is greater than two, so that the weave points of the weft-weighted plain weave and the breathable weave are opposite and can be either warp or weft weave points. The skeins are twisted on the other side of the fabric on both sides of the warp weave point. The warp yarns in the weft-weighted plain weave and the breathable weave are closely attached to each other.
[0007] In one embodiment, the breathable weave and the weft-flat weave are interspersed in a grid structure on the fabric, and the common multiple of the total number of warp yarns of the breathable weave and the total number of warp yarns of the weft-flat weave is the warp width of the grid structure, and the total number of warp yarns of the weft-flat weave is 2.
[0008] In one embodiment, the N groups of yarns are twisted sequentially in a beginning-to-end cycle when they interweave with the weft yarns along the warp direction.
[0009] In one embodiment, N equals three, and the three sets of yarns are numbered sequentially along the weft direction as first yarn, second yarn, and third yarn, and are twisted in the following order: first yarn twists second yarn and third yarn, second yarn twists third yarn and first yarn, and third yarn twists first yarn and second yarn.
[0010] A method for preparing breathable Oxford cloth, used to produce the breathable Oxford cloth as described above, includes the following steps: Step 1: The polyamide material is fed into an extruder to produce polyamide fibers. The polyamide fibers are then spun into yarns for weaving the fabric. Step 2: According to the required yarn count, the yarn is divided into warp yarn and weft yarn. After the warp yarn is passed through the warping machine, it is fed into the loom together with the weft yarn for weaving. The warp yarn includes N sets of skeins. During weaving, the N sets of skeins and the remaining warp yarns are sequentially passed into the ordinary heddles on the loom according to the weaving sequence. Step 3: During weaving, the loom uses a warp width M as a unit, and two units constitute one cycle. The two units weave together to form a breathable fabric structure that is staggered along the warp. In any given unit, the loom performs the following weaving actions to create an alternating breathable structure and a weft-weighted plain weave: a. After the ordinary heddles for weaving breathable structures are twisted, the drive motor of the loom drives the heddle frame, which in turn moves the ordinary heddles for weaving breathable structures as a whole, so that the breathable structures and the warp threads of the weft-weighted plain structures are close together. b. Ordinary heddles passing through N groups of skeins are skeins of each other. When the skeins of any group of skeins are at the position closest to the weft-weighted plain weave and interweave with the weft yarn to form a warp weave point, the skeins of the other groups press down on the two ends of the skeins forming the warp weave point in the warp direction through the right-hand passing method and the left-hand passing method, and interweave with the weft yarn in the same weft direction of the warp weave point to form a weft weave point. c. The skeins that form the warp weft points are woven together on the back of the fabric at the interlacing points that are close to each other in the warp direction; Step 4: Before winding, the fabric is fed into a device with several sets of rolling rollers for rolling the fabric. The fabric surface is rolled twice in the forward and reverse directions, so that the yarn at the warp point on the surface of the fabric being rolled by the rolling rollers is wound in the direction closer to the inside of the fabric and the middle of the breathable structure. Step 5: Heat-set the finished fabric and then cool it; Step 6: Apply a coating to the surface of the fabric using a coating machine to form the fabric body.
[0011] In one embodiment, the rolling roller in step four is a heated rolling roller.
[0012] Compared with the prior art, the above-mentioned technical solution provided in this application has the following advantages: the fabric body forms a breathable structure by setting N sets of twisted yarns along the warp direction, and N is greater than two, so that the weft flat weave and the breathable weave have opposite weave points. Without reducing the fabric structure density, multiple loops are formed on the breathable weave. The weft flat weave and the warp yarns in the breathable weave are set close together, which ensures that the yarn arrangement in the breathable weave area is compact, so that the fabric body retains the abrasion resistance required by Oxford cloth. The twisted yarns are twisted on the other side of the fabric on both sides of the warp weave point, and after subsequent rolling, the loops are wound inward. After the above-mentioned fabric is coated, each coil position forms an independent air cushion structure, which provides multiple points of elastic cushioning when the pet's paw steps on it. At the same time, the hollow opening of the coil structure is not completely sealed by the coating, allowing gas to flow along the coil axis, thus achieving localized ventilation after the coating is applied.

Detailed Implementation
[0014] To provide a clearer understanding of the technical features, objectives, and effects of this invention, the specific embodiments of this invention will now be described in detail with reference to the accompanying drawings. In the following description, it should be understood that the orientations or positional relationships indicated by terms such as "front," "rear," "upper," "lower," "left," "right," "longitudinal," "horizontal," "vertical," "horizontal," "top," "bottom," "inner," "outer," "head," and "tail" are based on the orientations or positional relationships shown in the accompanying drawings, and are constructed and operated in a specific orientation. They are only for the convenience of describing this technical solution and do not indicate that the device or element referred to must have a specific orientation. Therefore, they should not be construed as limitations on this invention.
[0015] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0016] This embodiment relates to a functional Oxford cloth for the surface of pet products, specifically a breathable Oxford cloth and its preparation method. When existing pet sleeping pads or travel bags use Oxford cloth as the outer layer, although it can resist scratching, the breathability is significantly reduced after the surface is coated with an anti-fouling coating.
[0017] A breathable Oxford cloth, such as Figures 1 to 2 As shown, it includes a fabric body and a coating applied to both sides of the fabric body. The fabric body is woven from yarns made of polyamide material, which can be nylon 6 or nylon 66. The breathable structure includes N sets of twisted yarns arranged along the warp direction. The N sets of twisted yarns are twisted together along the warp direction, where N is greater than two, so that the weft flat weave and the breathable structure are opposite in structure and can be warp weave points or weft weave points respectively. In this embodiment, N equals three. The three sets of yarns are numbered sequentially along the weft direction as the first yarn, the second yarn, and the third yarn. They are twisted in a cyclical manner, with the first yarn twisting the second and third yarns, the second yarn twisting the third yarn and the first yarn, and the third yarn twisting the first and second yarns. This arrangement makes the weft-weighted plain weave and the breathable weave opposite at their adjacent points. The adjacent points can be either warp or weft points. The yarns are twisted on the other side of the fabric on both sides of the warp point. The warp threads in the weft-weighted plain weave and the breathable weave are set close to each other. Due to the mutual twisting of the three sets of yarns, multiple loop structures are formed in the breathable weave. These loops will be further transformed into the basic shape of the cushioning air cushion in subsequent processes.
[0018] To further improve the uniformity of the breathable structure distribution on the fabric surface, the breathable structure and the weft-flat weave are interspersed in a grid structure on the fabric. The common multiple of the total number of warp yarns of the breathable structure and the total number of warp yarns of the weft-flat weave is the warp width of the grid structure. The total number of warp yarns of the weft-flat weave is 2. When the least common multiple is used, the distribution of the breathable structure and the weft-flat weave is the finest. This allows the breathable area to cover the contact area of the pet's paws more densely after the fabric is made into the surface of the pet sleeping pad. In addition, the three sets of skeins are twisted sequentially from beginning to end when they interweave with the weft yarns along the warp direction. The twisting pattern makes the structure of the breathable structure have strict periodicity, thereby ensuring the consistency of breathability performance throughout the fabric.
[0019] Beneficial effects: The fabric body forms a breathable structure by setting N sets of twisted yarns along the warp direction, and N is greater than two. This makes the weft plain weave and the breathable weave opposite at the adjacent weave points. Without reducing the fabric structure density, multiple loops are formed on the breathable weave. The weft plain weave and the warp yarns in the breathable weave are set close together, which ensures that the yarn arrangement in the breathable weave area is compact, so that the fabric body retains the abrasion resistance required by Oxford cloth. The twisted yarns are twisted on the other side of the fabric on both sides of the warp weave point, and after subsequent rolling, the loops are wound inward. After the above-mentioned fabric is coated, each coil position forms an independent air cushion structure, which provides multiple points of elastic cushioning when the pet's paw steps on it. At the same time, the hollow opening of the coil structure is not completely sealed by the coating, allowing gas to flow along the coil axis, achieving local ventilation after the coating is applied. Furthermore, since the coil after winding is above the breathable structure, the hollow structure is not easily contaminated at both ends under the cover of the coating.
[0020] This embodiment also provides a method for preparing the above-mentioned breathable Oxford cloth, such as... Figures 3 to 4 As shown, this method allows for the production of fabrics by modifying conventional shuttle looms, solving the problem of existing equipment being unable to weave a fabric that is both dense and breathable. The method includes the following steps: Step 1: The polyamide material is fed into an extruder to produce polyamide fibers. The polyamide fibers are then spun into yarns for weaving the fabric. In some embodiments, the heating temperature of the extruder is set in stages, gradually increasing from the feeding section to the metering section, in order to maintain the uniform flowability of the polyamide melt. A twisting step can be added in the spinning process to improve the breaking strength of the yarn.
[0021] Step 2: According to the required yarn count, the yarn is divided into warp and weft yarns. After the warp yarns are passed through the warping machine, they are fed into the loom together with the weft yarns for weaving. The warp yarns include three sets of skeins. During weaving, the three sets of skeins and the remaining warp yarns are sequentially passed into the ordinary heddles on the loom according to the weaving sequence. In some embodiments, the winding speed of the warping machine is lower than that of conventional chemical fiber warping to avoid uneven tangling of the yarn strands due to excessive tension.
[0022] Step 3: During weaving, the loom uses a warp width M as a unit, and two units constitute one cycle. The two units weave together to form a breathable fabric structure that is staggered along the warp. In any given unit, the loom performs the following weaving actions to create an alternating breathable structure and a weft-weighted plain weave: a. After the ordinary heddles for weaving breathable structures are twisted, the drive motor of the loom drives the heddle frame, which in turn moves the ordinary heddles for weaving breathable structures as a whole, so that the breathable structures and the warp threads of the weft-weighted plain structures are close together. In some embodiments, the drive motor is a servo motor, whose rotation angle is linearly related to the distance the heald frame moves. The controller presets the movement stroke so that the gap between the warp yarns of the breathable fabric and the warp yarns of the weft-weighted flat fabric is smaller than the diameter of a single yarn.
[0023] b. The ordinary heddles that pass through the three sets of slivers are slivers to each other. When the sliver of any set of slivers is closest to the weft-weighted plain weave and interweaves with the weft yarn to form a warp weave point, the slivers of the other sets of slivers press down on the two ends of the sliver that form the warp weave point through the right-hand and left-hand methods respectively, and interweave with the weft yarn in the same weft direction of the warp weave point to form a weft weave point.
[0024] c. The yarns that form the warp weft points are woven together on the back of the fabric at the interlacing points that are close to each other in the warp direction.
[0025] Step 4: Before winding, the fabric is fed into a device with several sets of rolling rollers for rolling the fabric. The fabric surface is rolled twice in the forward and reverse directions, so that the yarn at the warp point on the surface of the fabric being rolled by the rolling rollers is wound in the direction closer to the inside of the fabric and the middle of the breathable structure. In some embodiments, the rolling roller is a heated rolling roller with a heating temperature lower than the glass transition temperature of the polyamide material, making the yarn more prone to plastic crimping without elastic recovery when heated. Forward rolling causes the warp points on one side of the skein to be recessed towards the inside of the fabric, while reverse rolling causes the warp points on the other side of the skein to be recessed towards the inside of the fabric, forming a hollow winding structure similar to a tube.
[0026] Step 5: Heat-set the finished fabric and then cool it; In some embodiments, the heat setting temperature is 80% to 90% of the melting temperature of the polyamide material, the holding time is controlled between 30 seconds and 2 minutes, and then rapid cooling with cold air is used to lock the shape of the wound structure.
[0027] Step Six: Apply a coating to the surface of the fabric using a coating machine to form the fabric body; In some embodiments, the coating is made of TPU material and is applied by transfer coating or blade coating. The coating thickness is controlled at the micrometer level to prevent clogging of the hollow opening formed after the yarn is wound.
[0028] How to use: When the breathable Oxford cloth is made into a pet sleeping pad, the breathable side of the cloth faces the pet's contact surface. When the pet's paws step on the cloth, each wound yarn structure is compressed, the hollow part is compressed and the internal air is expelled, and the contact surface forms local elastic support. When the paws are lifted, the elastic recovery force of the wound structure causes it to reopen and draw in air, achieving the dual functions of breathability and cushioning. The coated TPU coating is located on both sides of the cloth, forming a discontinuous film layer at the opening of the wound structure, which can prevent liquid dirt from penetrating into the inner pad without completely sealing the air passage.
[0029] Beneficial effects: The breathable Oxford cloth in this embodiment forms a breathable structure by setting three sets of twisted yarns to form a breathable structure. After rolling, the warp points of the twisted yarns are rolled inward, creating multiple breathable micro-buffer units on the fabric. The coating is applied to both sides of the fabric. Due to the presence of the winding structure, the coating will not completely block the gas exchange path. At the same time, the winding structure increases the mechanical interlocking area between the coating and the yarn, reducing the risk of the coating being peeled off by pets. The weft-weighted plain weave and the warp of the breathable structure are set close together, ensuring that while the fabric has breathable areas, the overall abrasion resistance and tear resistance are not reduced due to the loose structure.
[0030] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
