Description

Technical Field

[0001] This invention relates to a fabric and manufacturing process, and in particular to a casual sports fabric with a ribbed appearance. Background Technology

[0002] In recent years, with market development and people's increasing pursuit of a better life, in addition to the usual comfort and functionality, consumers are also increasingly demanding fashion in casual fabrics. However, existing ribbed sports fabrics lack a three-dimensional feel, and there is a lack of three-dimensional pattern designs for such fabrics in the market. Summary of the Invention

[0003] The purpose of this invention is to provide a casual sports fabric with a ribbed appearance that can solve at least one of the above problems.

[0004] According to one aspect of the present invention, a casual sports fabric with a ribbed appearance is provided, comprising a fabric body, the fabric body including a face layer, an intermediate connecting layer and an inner layer, the face layer and the inner layer being connected by the intermediate connecting layer, the face layer using 50S / 1 Micro Modal compact Sirospun yarn and 50D / 36F low-elastic semi-dull polyester DTY wrapped with 30D spandex core-spun yarn as the face yarn, the intermediate connecting layer using 75D / 72F low-elastic semi-dull polyester DTY as the inner layer yarn and 30D spandex as the padding yarn, the fabric body having a weave structure of 4 needles and 8 yarns forming a complete cycle of double rib jacquard structure.

[0005] The beneficial effects of this invention are as follows: by using a blend of Modal and polyester, and weaving it with a double rib jacquard structure, the fabric surface is made of Modal, achieving a strong cotton-like feel, while the polyester is crisp and wrinkle-free, increasing the texture of the fabric; the ribbed appearance enhances the aesthetics of the fabric; through the outer and inner layers, with polyester as the skin-contact side and Modal as the fabric surface, the fabric maintains its cotton-like feel while the polyester is crisp, achieving a strong three-dimensional effect.

[0006] In some embodiments, the needle arrangement of the fabric body is as follows: the needle plate is arranged with two levels of needles (2 and 1); the needle cylinder is arranged with four levels of needles (1, 2, 3, and 4); the needle plate and needle cylinder are arranged in a needle-to-needle configuration. This facilitates the weaving of the fabric body.

[0007] In some implementations, the yarn arrangement of the fabric body is as follows: eight yarns form one cycle, with yarns 1 and 5 forming the middle connecting layer of the fabric body, yarns 2 and 6 forming the inner layer of the fabric body, and yarns 3, 7, 4, and 8 forming the outer layer of the fabric. This facilitates the connection between the layers of the fabric body and makes it easier to achieve the comfort of the inner layer against the skin.

[0008] In some implementations, the first and fifth rows use 75D / 72F low-elastic semi-dull polyester DTY as the intermediate connecting layer; the second and sixth rows use 75D / 72F low-elastic semi-dull polyester DTY as the inner layer yarn, knitted together with 30D spandex padding yarn, with all needles on the needle plate coming out and all needles on the cylinder knitting in stockinette stitch to form the inner layer of the fabric; the third and seventh rows use 50S / 1 Micro Modal compact Sirospun yarn, knitted in stockinette stitch with the first and second needles on the cylinder coming out and the third and fourth needles knitting in stockinette stitch; the fourth and eighth rows use 50D / 36F low-elastic semi-dull polyester DTY wrapped with 30D spandex core-spun yarn, knitted in stockinette stitch with the first and second needles on the cylinder knitting in stockinette stitch and the third and fourth needles coming out. This facilitates the knitting of each layer, achieves a skin-friendly inner layer, a strong three-dimensional effect on the fabric surface, and provides the fabric with a certain degree of moisture wicking.

[0009] In some embodiments, the yarn feed of the fabric body is as follows: calculated based on the length of 100 loops, the surface layer uses 17cm of 50S / 1 Micro Modal compact Sirospun yarn, and 15cm of 50D / 36F low-elastic semi-dull polyester DTY core-spun yarn wrapped with 30D spandex; the intermediate connecting layer uses 24cm of 75D / 72F low-elastic semi-dull polyester DTY; the inner layer uses 25cm of 75D / 72F low-elastic semi-dull polyester DTY; and the padding yarn is 9cm of 30D spandex. This helps to ensure the tightness of the fabric body and gives the fabric the appropriate elasticity.

[0010] According to another aspect of the present invention, a manufacturing process for a ribbed casual sports fabric is provided, comprising the following steps:

[0011] S1. Select a circular knitting machine based on the yarn arrangement and weaving structure of the fabric.

[0012] S2. The fabric body is woven in the selected circular knitting machine according to the yarn arrangement and weaving structure to obtain the fabric body.

[0013] S3. The fabric body obtained above is dyed and finished. The dyeing and finishing process is as follows: degreasing in a setting machine - pre-setting - dyeing - post-setting.

[0014] In some implementations, the 28-needle, 34-inch, 72-row weft knitting double-sided circular knitting machine selected in step S1 operates at a speed of 10-12 revolutions per minute. This satisfies the fabric knitting requirements.

[0015] In some embodiments, after the initial setting and degreasing in step S3, a first high-temperature initial setting is performed at a temperature of 190–200°C and a machine speed of 12–15 m / min. During the final setting of the fabric body, a temperature of 110–130°C and a machine speed of 15–20 m / min are used. The final fabric dimensions after final setting are 173cm * 320g / m².2 Therefore, the degreasing process of the setting machine is completed together with the first high-temperature initial setting. After the fabric is loosened, it passes through the degreasing device of the setting machine and is directly subjected to high-temperature initial setting. This process greatly shortens the production steps and reduces production costs. At the same time, since the fabric is directly put into the setting machine after degreasing, the risk of folding creases caused by excessively long stacking time of wet fabric is reduced, thus improving the quality stability of the product.

[0016] The fabric obtained through the above production process has stable quality and a smooth texture, thus improving the stability of fabric quality. At the same time, through the yarn arrangement method and weaving structure of this invention, the fabric forms a three-dimensional rib appearance, with a strong three-dimensional effect, a cotton-like touch, the crispness of polyester, and a certain moisture-wicking function. Attached Figure Description

[0017] Figure 1 This is a weave diagram of a casual sports fabric with a ribbed appearance. Detailed Implementation

[0018] The present invention will now be described in further detail with reference to the accompanying drawings.

[0019] Reference Figure 1 The attached diagram shows the weaving loops of the lining yarn (coarse yarns 2 and 6) and the weaving loops of the padding yarn (coarse yarns). A casual sportswear fabric with a ribbed appearance includes a fabric body comprising a face layer, an intermediate connecting layer, and an inner layer. The face layer and inner layer are connected by the intermediate connecting layer. The face layer uses 50S / 1 Micro Modal (superfine Modal fiber) compact Siro-spun yarn and 50D / 36F low-elastic semi-dull polyester DTY (Draw texturing yarn) wrapped with 30D spandex core-spun yarn as the face yarn. The intermediate connecting layer uses 75D / 72F low-elastic semi-dull polyester DTY. The inner layer uses 75D / 72F low-elastic semi-dull polyester DTY as the inner layer yarn and 30D spandex as the padding yarn. The fabric body's weave structure uses a complete cycle of double rib jacquard structure composed of 4 needles and 8 yarns.

[0020] The surface layer of this sports fabric uses 50S / 1 Micro Modal compact Siro-spun yarn, which is a short-fiber type with a strong cotton feel. In addition, the compact Siro-spun yarn has a good pilling effect. By selecting the yarn of the middle connecting layer, the thickness and density of the fabric can be increased.

[0021] The casual sports fabric with a ribbed appearance of the present invention is knitted using a 28-needle, 34-inch, 72-way weft knitting double-sided circular knitting machine, which facilitates the knitting of the fabric.

[0022] The needle arrangement of the fabric body is as follows: the needle plate is arranged with two levels of needles, 2 and 1; the needle cylinder is arranged with four levels of needles, 1, 2, 3 and 4; the needle plate and needle cylinder are arranged in a needle-to-needle configuration.

[0023] The fabric body is arranged in a single loop of eight yarns. Yarns 1 and 5 form the middle connecting layer of the fabric body, yarns 2 and 6 form the inner layer of the fabric body, and yarns 3, 7, 4, and 8 form the outer layer of the fabric. This facilitates the connection between the outer layer and the inner layer by the middle connecting layer.

[0024] The first and fifth rows use 75D / 72F low-elastic semi-dull polyester DTY as the intermediate connecting layer; the second and sixth rows use 75D / 72F low-elastic semi-dull polyester DTY as the inner layer yarn, knitted together with 30D spandex padding yarn, with all needles on the needle plate coming out and all needles on the cylinder knitting in stockinette stitch to form the inner layer of the fabric; the third and seventh rows use 50S / 1 Micro Modal compact Sirospun yarn, knitted in stockinette stitch with the first and second needles on the cylinder coming out and the third and fourth needles knitting in stockinette stitch; the fourth and eighth rows use 50D / 36F low-elastic semi-dull polyester DTY wrapped with 30D spandex core-spun yarn, knitted in stockinette stitch with the first and second needles on the cylinder knitting in stockinette stitch and the third and fourth needles coming out.

[0025] Therefore, after the fabric body is woven, the difference in thickness between the 50S / 1 Micro Modal compact Siro-spun yarn and the 50D / 36F low-elastic semi-dull polyester DTY yarn wrapped with 30D spandex core-spun yarn, as well as the difference in tightness during the weaving process, is used to form a three-dimensional rib appearance surface structure, which makes the fabric have a strong three-dimensional effect and meets the corresponding usage requirements.

[0026] The yarn feed for the fabric body is as follows: calculated based on the length of 100 loops, the surface layer uses 17cm of 50S / 1 Micro Modal compact Sirospun yarn, and 15cm of 50D / 36F low-elastic semi-dull polyester DTY core-spun yarn wrapped with 30D spandex; the middle connecting layer uses 24cm of 75D / 72F low-elastic semi-dull polyester DTY; the inner layer uses 25cm of 75D / 72F low-elastic semi-dull polyester DTY, and the padding yarn is 9cm of 30D spandex. This gives the fabric body a certain degree of elasticity and resilience.

[0027] The present invention discloses a manufacturing process for a ribbed casual sports fabric, comprising the following steps:

[0028] S1. Select a circular knitting machine based on the yarn arrangement and weaving structure of the fabric.

[0029] S2. The fabric body is woven in the selected circular knitting machine according to the yarn arrangement and weaving structure to obtain the fabric body.

[0030] S3. The fabric body obtained above is dyed and finished. The dyeing and finishing process is as follows: degreasing in a setting machine - pre-setting - dyeing - post-setting.

[0031] In step S1, the 28-needle, 34-inch, 72-row weft knitting double-sided circular knitting machine is selected, with a machine speed of 10-12 revolutions per minute. This meets the weaving requirements of the fabric.

[0032] In step S3, after setting and degreasing, a first high-temperature initial setting is performed at a temperature of 190–200℃, with a machine speed of 12–15 m / min. The fabric specifications upon exiting the machine are: 190cm * 300g / m. 2 This ensures stable fabric specifications and reduces crease formation during the dyeing process.

[0033] When the fabric is post-set, the temperature is 110-130℃ and the machine speed is 15-20m / min. The final fabric dimensions after post-setting are 173cm*320g / m². 2 Therefore, the degreasing process of the setting machine is completed together with the first high-temperature initial setting. After the fabric is loosened, it passes through the degreasing device of the setting machine and is directly subjected to high-temperature initial setting. This process greatly shortens the production steps and reduces production costs. At the same time, since the fabric is directly put into the setting machine after degreasing, the risk of folding creases caused by excessively long stacking time of wet fabric is reduced, thus improving the quality stability of the product.

[0034] After the pre-setting process in step S3, the fabric comes off the machine with the following specifications: 190cm * 300g / m 2 This ensures stable fabric dimensions and minimizes creases during the dyeing process. Dyeing is performed using existing liquid flow dyeing machines, with a hair-reducing agent added to the dye bath.

[0035] The casual sports fabric with a ribbed appearance obtained by the production process of this invention was tested. The test results are as follows: Under standard laboratory conditions of 20°C and 65% humidity, the fabric's dry rubbing fastness is ≥3-4, wet rubbing fastness is ≥3, wash fastness (color change) is ≥3-4, and staining is ≥3; water fastness (color change) is ≥3-4, and staining is ≥3. Tensile testing using LTD03 7.5LBS clamps showed the fabric's elongation at 53% warp and 40% weft, with a recovery rate of 98% warp and 96% weft. ASTM D3939 testing for snagging showed warp grade 3-4 and weft grade 4. GB / T 4802.1E testing for pilling showed warp grade 3-4 and weft grade 3-4.

[0036] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the inventive concept of the present invention, and these all fall within the protection scope of the present invention.
