Description

Technical Field

[0001] The invention relates to the field of textile technology, in particular to a waffle fabric and a weaving method thereof. Background Art

[0002] Waffle fabric is a fabric with a waffle pattern (i.e., a lattice-like concave-convex pattern), which has a rich sense of layering and is therefore popular among consumers. Waffle fabric can be used for bedding, clothing, decorative items, etc., and has the advantages of being beautiful and crisp.

[0003] In the prior art, a waffle fabric is obtained by knitting with an ordinary rib knitting method, and the waffle effect is obvious. Figure 1 and Figure 2 As shown, taking the ordinary eight-way knitting method as an example, the upper and lower discs are grouped into three needles. The first way: the 1st and 2nd needles of the upper disc are looped, and the 3rd needle is pulled out; the 1st needle of the lower disc is pulled out, and the 2nd and 3rd needles are looped. In the second, third and fourth ways: the 1st and 2nd needles of the upper disc are held, and the 3rd needle is pulled out; the 1st needle of the lower disc is pulled out, and the 2nd and 3rd needles are looped. The knitting method of the fifth way is the same as the knitting method of the first way, and the knitting methods of the sixth, seventh and eighth ways are the same as the second, third and fourth ways.

[0004] Due to the large number of needles drawn on both sides, the formed tissue structure causes the waffle fabric to have problems such as unstable shrinkage, looseness, and difficulty in controlling the weight and width. In order to improve the above problems, a stretching frame is arranged, that is, the method of adding spandex yarn is used for improvement, but it is easy to cause problems of reverse stretching frame and exposed stretching frame, which affects the appearance of the waffle fabric.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.

[0031] Implementation Method 1

[0032] like Figure 3 and Figure 4 As shown, the present invention provides a method for weaving a waffle fabric, which adopts a double-face knitting method to weave yarn into a waffle fabric with a waffle effect.

[0033] contrast Figures 1 to 4 Compared with the waffle fabric woven by the rib pair knitting method in the prior art, the waffle fabric with the waffle concave-convex pattern effect is woven by the double-sided knitting method in the present invention. By controlling the upper plate not to draw needles and only the lower needles in the drawing area of ​​the lower plate to draw needles, the fabric structure of the waffle fabric of the present invention is more stable, and thus the size is more stable. It is easier to control the shrinkage width and grammage width, and it is impossible to add spandex yarn to the yarn, so the problems of reverse tension and exposed tension will not occur. In addition, there is no need to upgrade and transform the existing equipment and accessories to implement the weaving method of the present invention to produce the waffle fabric of the present invention, and the cost is low; the finished fabric has a special effect and strong usability.

[0034] Specifically, the knitting method of the present invention can be implemented using an existing double knitting machine. The type of yarn may not be specifically limited, and can be selected according to demand; for example, in some embodiments of the present invention, the yarn includes a first yarn, and the first yarn is cotton yarn, cotton-polyester blended yarn or short-fiber blended yarn. In some embodiments of the present invention, the yarn also includes a second yarn, and the yarn is interwoven or mixed with the first yarn; wherein the second yarn is one or more of polyester yarn, nylon yarn, Tencel fiber, modal fiber and man-made fiber. By using different yarns in combination, the waffle fabric has different characteristics to better meet different usage requirements. The yarn count of the yarn may not be specifically limited, and can be selected according to demand; such as yarns of yarn counts such as 20S, 26S, 30S, 32S, and 40S. The color of the yarn can be one, or a combination of multiple colors can be used to obtain a waffle effect with richer colors.

[0035] In addition, the weaving method of the present invention can further include pre-setting, dyeing, washing and setting after the waffle fabric is woven, wherein the specific processing steps of pre-setting, dyeing, washing and setting are the same as those in the prior art and are not described in detail here. After the waffle fabric is woven, it can also be finished as needed, such as one of the finishing methods of singeing, enzyme washing, mercerizing, and liquid ammonia mercerizing or a combination of multiple finishing methods.

[0036] like Figure 3 As shown, in the embodiment of the present invention, by adopting the double-face knitting method to weave the yarn to obtain the waffle fabric, the number of needle withdrawals in the knitting process can be effectively reduced, and no needle is required, thereby further improving the dimensional stability of the waffle fabric and the controllability of the shrinkage width and grammage width. As in some embodiments of the present invention, the knitting method of the present invention includes a plurality of knitting cycles repeated in sequence, each knitting cycle includes a plurality of knitting strokes, in each knitting stroke, the upper needles of the upper plate are not drawn, and the lower plate is provided with a plurality of needle withdrawal areas B, and the lower needles located in the needle withdrawal areas B are all drawn.

[0037] Combination Figure 4 and Figure 6 As shown, in an embodiment of the present invention, the lower needles of the lower disk cooperate to weave to form the front side of the waffle fabric, and the upper needles of the upper disk cooperate to weave to form the back side of the waffle fabric; wherein, the front side of the waffle fabric has a waffle effect, and the back side of the waffle fabric has a flat effect.

[0038] It should be understood that the double-sided knitting method uses two rows of needles arranged opposite to each other for knitting, wherein any row of needles can be defined as the upper needles of the upper plate to cooperate in knitting to form the reverse side of the waffle fabric, and the other row of needles can be defined as the lower needles of the lower plate to cooperate in knitting to form the front side of the waffle fabric.

[0039] Specifically, the lower disk is alternately provided with a plurality of needle exiting areas A and a plurality of needle withdrawal areas B; the knitting cycle comprises: a first knitting stroke: the upper needles of the upper disk are alternately inserted into loops, and the lower needles located in the needle exiting area A are alternately inserted into loops; a second knitting stroke: the upper needles of the upper disk are alternately inserted into loops and are complementary to the insertion of the upper needles in the first knitting stroke, and the lower needles located in the needle exiting area A are alternately inserted into loops and are complementary to the insertion of the lower needles in the first knitting stroke, that is, the insertion of the needles of the upper disk and the insertion of the lower disk in the second knitting stroke are complementary to the insertion of the needles of the upper disk and the insertion of the lower disk in the first knitting stroke, that is, the upper needles of the upper disk that did not insert needles and the lower needles that did not insert needles in the needle exiting area A in the first knitting stroke insert needles in the second knitting stroke, and the upper needles of the upper disk that inserted needles and the lower needles of the needle exiting area A in the first knitting stroke do not insert needles in the second knitting stroke; a third knitting stroke: none of the upper needles of the upper disk insert needles, and the lower needles located in the needle exiting area A all insert needles into loops.

[0040] like Figure 3As shown, in the first knitting stroke and the second knitting stroke, the number of alternating needles of the upper needles of the upper disk and the number of alternating needles of the lower needles located in the needle exit area A are not specifically limited. For example, in the preferred embodiment of the present invention, the needles are alternately inserted one by one. For example, in the first knitting stroke, the upper needles of the 2nd, 4th, and 6th are inserted, while the upper needles of the 1st, 3rd, and 5th are not inserted. In the second knitting stroke, the upper needles of the 1st, 3rd, and 5th are inserted, while the upper needles of the 2nd, 4th, and 6th are not inserted. Thus, the dimensional stability of the waffle fabric and the controllability of the shrinkage width and the grammage width can be further improved. Of course, it can also be two-by-two alternating needles or other numbers of alternating needles. For example, in the first knitting stroke, the upper needles of the 1st, 2nd, 5th, and 6th are inserted, while the upper needles of the 3rd and 4th are not inserted. In the second knitting stroke, the upper needles of the 3rd and 4th are inserted, while the upper needles of the 1st, 2nd, 5th, and 6th are not inserted.

[0041] Combination Figure 3 , Figure 4 as well as Figure 5 As shown, the number of lower needles in the needle-exiting area A and the number of lower needles in the needle-drawing area B in each knitting stroke may not be specifically limited, and can be selected according to the desired waffle pattern size to form waffle effects of different sizes; wherein, the more the number of lower needles in the needle-drawing area B, the greater the width w of the longitudinal line Y of the waffle. y The wider it is, the narrower it is; the more the number of needles in the needle exit area A is, the greater the horizontal spacing j between two adjacent longitudinal lines Y of the waffle. y The wider it is, the narrower it is. For example, the lower stitches of the lower plate can be grouped into six stitches, with two stitches drawn every four stitches, or grouped into five stitches, with one stitch drawn every four stitches, or grouped into four stitches, with two stitches drawn every two stitches, or any other number combination. Figure 3 , Figure 4 as well as Figure 5 As shown, in the embodiment of the present invention, in each weaving cycle, before the third weaving stroke is performed, the first weaving stroke and the second weaving stroke are repeated alternately. The number of times the first weaving stroke and the second weaving stroke are repeated alternately is not specifically limited, and can be selected according to the desired waffle pattern size to form waffle effects of different sizes; wherein, the more the number of alternating repetitions, the greater the longitudinal spacing j between two adjacent transverse lines X of the waffle. x The wider it is, the narrower it is. In addition, in each weaving cycle, the third weaving stroke is repeated continuously. The number of times the third weaving stroke is repeated continuously may also be not specifically limited to form waffle effects of different sizes; wherein, the greater the number of continuous repetitions, the greater the width w of the horizontal line X of the waffle. x The wider it is, the narrower it is.

[0042] Combination Figure 3 , Figure 4 as well as Figure 5As shown, in the embodiment of the present invention, in the process of the knitting cycle, the combination of waffle effects of different sizes can be formed by changing the number of needles in the needle exit area A, the number of needles in the needle withdrawal area B, the number of alternating repetitions of the first knitting stroke and the second knitting stroke, and / or the number of continuous repetitions of the third knitting stroke in each knitting cycle and / or each knitting stroke. For example, in a specific embodiment, in each knitting stroke, the number of needles in each needle withdrawal area B remains unchanged, wherein the number of needles in multiple needle exit areas A is greater than the number of needles in another multiple needle exit areas A, so that the lateral spacing j between two adjacent longitudinal lines Y in a part of the waffle is y is relatively wide, while the horizontal spacing j between two adjacent longitudinal lines Y in the other part of the waffle is y Relatively narrow, that is, one area of ​​the waffle fabric forms a wide waffle effect, and another area forms a narrow waffle effect.

[0043] However, since the dimensional stability of the waffle, the controllability of the shrinkage width and the weight width, and the three-dimensional effect of the waffle pattern are all related to the pattern size, Figure 3 and Figure 4 As shown, in the embodiment of the present invention, the number of lower needles in each needle exit area A is four needles; the number of lower needles in each needle withdrawal area B is two needles; that is, in each knitting stroke, the lower needles in the lower plate are grouped into six needles, and two needles are withdrawn every four needles. In the knitting cycle, the first knitting stroke and the second knitting stroke are repeated four times alternately, thereby sequentially forming the first route, the second route, the third route, the fourth route, the fifth route, the sixth route, the seventh route, and the eighth route in the knitting cycle. In each knitting cycle, the third knitting stroke is repeated twice continuously, thereby sequentially forming the ninth route and the tenth route in the knitting cycle; thereby effectively improving the dimensional stability, shrinkage width, and gram weight width controllability of the waffle, while also ensuring the three-dimensional effect of the waffle pattern.

[0044] Combination Figure 3 and Figure 4 As shown, in order to better understand and implement the weaving method of the waffle fabric of the present invention, a specific embodiment is provided as follows:

[0045] Each knitting cycle has a total of ten loops. The upper needles of the upper plate do not draw any stitches, and the lower needles of the lower plate are grouped into six stitches, and two stitches are drawn every four stitches.

[0046] First route: The 2nd, 4th and 6th stitches of the upper plate are looped; the 1st and 3rd stitches of the lower plate are looped, and the 5th and 6th stitches are pulled out;

[0047] Second route: The 1st, 3rd and 5th needles of the upper plate are looped; the 2nd and 4th needles of the lower plate are looped, and the 5th and 6th needles are withdrawn;

[0048] The third route: the same weaving method as the first route;

[0049] The fourth route: the same weaving method as the second route;

[0050] The fifth route: the same weaving method as the first route;

[0051] Sixth route: the same weaving method as the second route;

[0052] The seventh route: the same weaving method as the first route;

[0053] The eighth route: the same weaving method as the second route;

[0054] Ninth route: All upper needles of the upper plate are not removed; the 5th and 6th needles of the lower plate are removed;

[0055] The tenth route: The weaving method is the same as the ninth route.

[0056] Implementation Method 2
