Description

Technical Field

[0001] This utility model relates to a double-layered fabric, and more particularly to an ultra-elastic sandwich fabric. Background Technology

[0002] Knitted sandwich fabric, known in the industry as Spacer or double-layered fabric, is commonly used for women's bra cups. In recent years, various Spacer fabrics have been widely used to replace traditional foam cups; however, most Spacer fabrics on the market have low elasticity, which limits their ability to be molded into large cups, and they are prone to wrinkling after molding, affecting their appearance. Furthermore, with women's underwear increasingly prioritizing comfort, traditional Spacer fabrics, limited by low elasticity, are also not comfortable enough. Utility Model Content

[0003] The purpose of this invention is to provide an ultra-elastic sandwich fabric that can solve at least one of the above problems.

[0004] According to one aspect of the present invention, a super-elastic sandwich fabric is provided, comprising a fabric body, the fabric body including an upper layer, a lower layer and a connecting layer, the connecting layer being located between the upper layer and the lower layer, the upper layer and the lower layer being connected by the connecting layer, the upper layer being woven with 30D / 12F~40D / 48F semi-dull polyester FDY outer yarn and 20D~40D spandex padding yarn, the lower layer being woven with 40D / 48F~75D / 144F low-elastic semi-dull polyester DTY skin-adhesive yarn and 20D~40D spandex padding yarn, the connecting layer being woven with 30D / 1F~40D / 1F semi-dull polyester monofilament FDY connecting yarn, the upper layer being composed of two looped knitting loop rows and two looped knitting loop columns as the basic cycle, the lower layer being composed of two looped knitting loop rows and two looped knitting loop columns as the basic cycle, and the connecting layer being composed of two staggered tucked knitting loop rows and two staggered tucked knitting loop columns as the basic cycle.

[0005] The beneficial effects of this utility model are: through the weaving structure of the upper layer, lower layer and connecting layer, the entire fabric body has good elasticity, preventing wrinkling during production molding, and is suitable for large cup molding; at the same time, due to the great elasticity, it is softer overall, more comfortable to wear, and can be suitable for underwear of various sizes, with good applicability.

[0006] In some implementations, the weaving structure of the fabric body is as follows:

[0007] Row 1: One of the connecting layers is formed by using a method where odd-numbered needles on the needle plate are not knitted and even-numbered needles are tucked together, and odd-numbered needles on the needle cylinder are tucked together and even-numbered needles are not knitted.

[0008] The fourth row: The second connecting layer is formed by using the method of tucking the odd number of needles on the needle plate and leaving the even number of needles unknitted, and leaving the odd number of needles on the needle cylinder unknitted and tucking the even number of needles.

[0009] Rows 2 and 5: The lower layer is formed by knitting in circles with all needles on the needle plate and not knitting with any needles on the needle cylinder.

[0010] Rows 3 and 6: These rows employ a technique where all needles on the cylinder knit in loops, while all needles on the dial remain unknitted, forming the upper layer. Through these various knitting methods, the fabric itself can be knitted, ensuring a smooth connection between the upper, connecting, and lower layers.

[0011] In some implementations, the fabric body uses a double-sided needle arrangement during knitting, with the upper needles arranged in a 1, 2 pattern and the lower needles arranged in a 2, 1 pattern. This facilitates meeting the knitting requirements of the fabric body.

[0012] In some embodiments, the weaving method of the fabric body is as follows: connecting yarns are woven in the 1st and 4th layers; skin-adhesive yarns and padding yarns are woven in the 2nd and 5th layers; and outer yarns and padding yarns are woven in the 3rd and 6th layers. This facilitates the weaving of each upper layer, connecting layer, and lower layer.

[0013] In some embodiments, the yarn feed rate of the fabric body is 100 stitches: the feed length of the connecting yarns of F1 and F4 is 400-500 mm; the feed length of the outer yarns of F2 and F5 is 300-340 mm; the feed length of the inner yarns of F3 and F6 is 300-340 mm; and the feed length of all the padding yarns is 100-130 mm. Therefore, by using this yarn feed rate, the entire fabric body can achieve a better effect of ultra-high elasticity.

[0014] In some embodiments, the longitudinal elongation of the fabric body is 150-200%, and the transverse elongation is 240-300%. As a result, the fabric body achieves a super elastic effect in both the transverse and longitudinal directions. Attached Figure Description

[0015] Figure 1 This is a triangle diagram illustrating the weaving process of an ultra-elastic sandwich fabric.

[0016] Figure 2 This is a schematic diagram of the weave structure of an ultra-elastic sandwich fabric. Detailed Implementation

[0017] The present invention will now be described in further detail with reference to the accompanying drawings.

[0018] Reference Figures 1-2The super-elastic sandwich fabric consists of the fabric body, which includes an upper layer, a lower layer, and a connecting layer. The connecting layer is located between the upper and lower layers and is connected to them. The upper layer is woven with 30D / 12F~40D / 48F semi-dull polyester FDY (FULLY DRAWN YARN) outer yarn and 20D~40D spandex padding yarn. The lower layer is woven with 40D / 48F~75D / 144F low-elastic semi-dull polyester DTY skin-adhesive yarn and 20D~40D spandex padding yarn. The connecting layer is woven with 30D / 1F~40D / 1F semi-dull polyester monofilament FDY connecting yarn.

[0019] By selecting the upper layer yarn, the fabric can maintain its shape well; by selecting the lower layer yarn, the surface against the skin feels softer and is more comfortable to wear; by selecting the connecting layer yarn, the entire fabric is made more structured.

[0020] In the actual weaving process, the upper layer of the fabric can be made of 40D / 48F semi-dull polyester FDY outer yarn and 20D spandex padding yarn, woven on the cylinder of a double-sided circular knitting machine, consisting of two rows of looped knitting loops and two rows of looped knitting loops as the basic cycle. The lower layer can be made of 75D / 144F low-elastic semi-dull polyester DTY skin-adhesive yarn and 20D spandex padding yarn, woven on the needle plate of a double-sided circular knitting machine, consisting of two rows of looped knitting loops and two rows of looped knitting loops as the basic cycle. The connecting layer can be made of 40D / 1F semi-dull polyester monofilament FDY connecting yarn, woven on the needle plate and cylinder of a double-sided circular knitting machine in a needle-containing manner, serving to connect the upper and lower layers, consisting of two rows of interlaced looped knitting loops and two rows of interlaced looped knitting loops as the basic cycle.

[0021] The weave structure of the fabric itself is as follows:

[0022] Row 1: One of the connecting layers is formed by using a method where odd-numbered needles on the needle plate are not knitted and even-numbered needles are tucked together, and odd-numbered needles on the needle cylinder are tucked together and even-numbered needles are not knitted.

[0023] The fourth method involves using the method of tucking odd-numbered needles on the needle plate and leaving even-numbered needles unknitted, and leaving odd-numbered needles on the needle cylinder and tucking even-numbered needles together to form the second connecting layer. Thus, the connecting layer is obtained through the first and fourth methods, which allows the connecting layer to connect the upper and lower layers well.

[0024] Rows 2 and 5: The lower layer is formed by knitting in circles with all needles on the needle plate and not knitting with any needles on the needle cylinder.

[0025] Rows 3 and 6: The upper layer is formed by knitting in circles with all needles on the cylinder and not knitting with any needles on the dial.

[0026] The fabric body uses a double-sided needle arrangement during knitting, with the upper needles arranged in a 1, 2 pattern and the lower needles arranged in a 2, 1 pattern.

[0027] The fabric body's yarn dropping method is as follows: connecting yarns are dropped on F1 and F4; skin-adhesive yarns and padding yarns are dropped on F2 and F5; and outer yarns and padding yarns are dropped on F3 and F6.

[0028] The yarn feed of the fabric body uses 100 stitches: the yarn feed length of the connecting yarn of 1F and 4F is 400-500mm; the yarn feed length of the outer yarn of 2F and 5F is 300-340mm; the yarn feed length of the skin-hugging yarn of 3F and 6F is 300-340mm; and the yarn feed length of all the padding yarns is 100-130mm.

[0029] The longitudinal elongation of the fabric body is 150-200%, and the transverse elongation is 240-300%.

[0030] Therefore, based on the aforementioned weaving structure, yarn feed, and corresponding yarns, the resulting fabric body has a width of 152cm and a weight of 350g / m². 2 It is lightweight; and the resulting sandwich fabric has super elasticity, with very high horizontal and vertical stretch rates, which can fit different cup sizes. It is more comfortable to wear than traditional Spacer fabric, has a softer feel against the skin, and is less prone to wrinkling after molding.

[0031] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
