Description

[Technical Field]

[0001] The present invention relates to knitted fabrics and garments. [Background technology]

[0002] Patent Document 1 describes a conventional fabric. The fabric described in Patent Document 1 includes a first main yarn and a second main yarn, which are knitted by a circular knitting machine to form the main body of the fabric. The first main yarn and the second main yarn each extend in the weft direction (horizontal direction) while forming multiple rows of loops, and the positions of the loops of the first main yarn correspond one-to-one to the positions of the loops of the second main yarn. Each loop of the first main yarn is positioned above a loop of the second main yarn. In the fabric of Patent Document 1, the second main yarn contains a polyurethane (spandex) yarn, which increases the elastic recovery of the second main yarn.

[0003] Patent Document 2 describes a tensile recovery fabric. The fabric in Patent Document 2 is warp knitted (vertical knitted) and includes main wires and auxiliary wires. The main wires have figure-eight nodes wound continuously in the warp direction (vertical direction), and the figure-eight nodes are equidistant and intertwined with each other. The auxiliary wires are formed by weaving together multiple horizontal and vertical yarns, and ventilation holes are provided between the horizontal and vertical yarns.

[0004] Additionally, there is a type of knit fabric that can be knitted on a circular knitting double-face machine called a punch-roma structure. When a circular knitting double-face machine knits punch-roma structure fabric, four yarn feeders are assigned to one knitting unit (one knitting cycle) of the fabric. Of the four yarn feeders, yarn feeders 1 and 2 are assigned to double-face knitting, yarn feeder 3 is assigned to tubular knitting with the upper needle (upper needle board), and yarn feeder 4 is assigned to tubular knitting with the lower needle (lower needle barrel). Punch-roma structure fabrics have the characteristics of a stable structure, less tendency for the edges of the fabric to curl, and less tendency for fibers to fall off, and are used for outerwear, sportswear, uniforms, work clothes, etc. [Prior art documents] [Patent documents]

DETAILED DESCRIPTION OF THE INVENTION

[0024] The present invention will be described in detail below with reference to specific embodiments. The embodiments described herein are merely intended to facilitate understanding of the present invention and should not be construed as limiting the technical scope of the present invention to specific forms. The specific examples shown in this specification are intended to explain the contents of the present invention to those skilled in the art by referring to the examples, and are not intended to limit the technical scope of the present invention to the specific examples.

[0025] The knitted fabric provided by the present invention comprises a first yarn and a second yarn, the first yarn being made of a highly abrasion-resistant nylon or polyester material, and the second yarn being a composite yarn (covered yarn) with an outer layer (sheath yarn) and an inner layer (core yarn).

[0026] The first thread may be, for example, a CORDURA (registered trademark) thread. CORDURA is a synthetic fiber sold by INVISTA. CORDURA is mainly made of nylon, specifically nylon 6,6, for example. The first thread may be a CORDURA nylon filament or a blended staple fiber yarn made by blending nylon staple fiber and cotton staple fiber.

[0027] Cordura fiber has excellent abrasion resistance, tear resistance, and strength due to its special material and structure. The knitted fabric provided by this invention contains Cordura fiber yarn, which can achieve excellent abrasion resistance both against external friction and friction between fabrics.

[0028] The outer layer of the second yarn is nylon or polyester yarn, and the inner layer is polyurethane yarn. By including the second yarn, which is a composite yarn of the outer and inner layers, the knitted fabric provided by the present invention has very good tightness and excellent elasticity, is wrinkle-resistant, and is also durable.

[0029] By including the first yarn and the second yarn, the knitted fabric and the garments including this knitted fabric provided by the present invention are both abrasion-resistant and elastic, and are highly comfortable.Furthermore, the knitted fabric and the garments provided by the present invention have excellent abrasion resistance, while also having a dense, thick feel and tensile recovery.

[0030] The knitted fabric provided by the present invention preferably has a first yarn (e.g., Cordura yarn) arranged on one side and the other side of the fabric, and a second yarn (composite yarn) moving back and forth between the two sides of the fabric, interwoven with the first yarn on one side and the other side of the fabric. With this structure, the first yarn is arranged on both sides of the fabric, providing abrasion resistance. Furthermore, the second yarn connects (interwoven with) both sides of the fabric, resulting in a fabric with excellent tightness and elasticity, wrinkle resistance, and a tight, thick feel and tensile recovery.

[0031] A fabric in which the first yarn is placed on both sides of the fabric and the second yarn connects the two sides may have a structure such as a ponte roma structure knitted from the first yarn and the second yarn. A ponte roma structure has the characteristics of being structurally stable, preventing fiber shedding, and preventing edge curling.

[0032] Specifically, a fabric with a pontiroma structure may have one knitting unit consisting of two first yarns arranged on one side and the other side of the fabric, and two second yarns that travel back and forth between the two sides of the fabric and interlace with the first yarns on the one side and the other side of the fabric. A fabric with this structure may be knitted, for example, on a circular knitting double-sided machine in which four yarn feeders are assigned to one knitting unit (one knitting cycle) of the fabric (four yarn feeders in one cycle). By using such a circular knitting double-sided machine with a 2:2 ratio of yarn feeders for the first yarns to yarn feeders for the second yarns, the knitted fabric provided by this invention can be produced industrially.

[0033] In the knitted fabric provided by the present invention, the yarn used as the first yarn may be a filament yarn made of long fibers (filaments), or a blended staple yarn made by blending staple fibers (staples).

[0034] When the first yarn is a filament yarn (e.g., Cordura filament yarn), its thickness may be 20D to 150D. Specific examples of thicknesses between 20D and 150D include 20D, 30D, 40D, 50D, 70D, 100D, 120D, and 150D, and may be a range formed by any two of these. Here, the "D" used as a unit of thickness stands for denier. Denier is a numerical value representing the weight of a 9000-meter length of yarn, and 1 gram of weight for a 9000-meter length is 1 denier. The higher the denier number, the thicker the yarn.

[0035] Furthermore, when the first yarn is a blended staple yarn (for example, a Cordura blended staple yarn, which is a blend of nylon staple and cotton), its thickness is preferably 20 / 1 to 50 / 1. Specific examples of thicknesses between 20 / 1 and 50 / 1 include 20 / 1, 30 / 1, 40 / 1, and 50 / 1, and may be any range formed by any two of these. Here, a number such as 20 / 1 representing thickness indicates the English count. The English count indicates the length (how many times 40 yards) per pound (at the official moisture content), and the larger the number, the thinner the yarn. The English count is sometimes expressed with the unit symbol "s." Furthermore, " / 1" indicates a single yarn (not a twisted yarn).

[0036] When the first yarn is a blended staple fiber yarn, the first yarn may be, for example, a blend of nylon staple fiber and cotton fiber. When the first yarn is a blend of nylon staple fiber and cotton fiber, the mass of the nylon staple fiber may account for 30 wt% to 50 wt% (weight percent) of the total mass, and the mass of the cotton fiber may account for 50 wt% to 70 wt% of the total mass.

[0037] The mass of nylon staple fiber being 30 wt% to 50 wt% of the total means that when the weight of the blended staple fiber yarn in which nylon staple fiber and cotton fiber are blended is taken as 100%, the weight of nylon staple fiber is 30% to 50% of the total. Specifically, the weight of nylon staple fiber may be 32%, 34%, 36%, 38%, 40%, 42%, 44%, 46%, 48%, 50%, etc.

[0038] Furthermore, when the mass of cotton fiber accounts for 50 to 70 wt% of the total, it means that when the weight of the blended staple fiber yarn in which nylon staple fiber and cotton fiber are blended is taken as 100%, the weight of cotton fiber accounts for 50 to 70% of the total. Specifically, the weight of cotton fiber may be 50%, 52%, 54%, 56%, 58%, 60%, 62%, 64%, 66%, 68%, 70%, etc.

[0039] The nylon or polyester yarns constituting the outer layer of the second composite yarn may independently have a thickness of 30D to 150D, such as 30D, 40D, 50D, 60D, 70D, 80D, 90D, 100D, 110D, 120D, 130D, 140D, or 150D, or any two of these thicknesses may be within the range.

[0040] The polyurethane yarns constituting the inner layer of the second composite yarn may independently have a thickness of 10D to 40D. The thickness of 10D to 40D may be, for example, 10D, 20D, 30D, 40D, etc., and may be any two of these thicknesses.

[0041] The clothing provided by the present invention is made from the knitted fabric having the above-mentioned abrasion resistance and tight elasticity. For example, a cut-and-sew fabric may be formed from the knitted fabric having the above-mentioned abrasion resistance and tight elasticity, and the cut-and-sew fabric may be sewn together to form the clothing. Alternatively, the entire clothing may be knitted from the knitted fabric having the above-mentioned abrasion resistance and tight elasticity.

[0042] The surface (front and back) of the knitted fabric provided by this invention is knitted with a first yarn made of a highly abrasion-resistant nylon or polyester material such as CORDURA yarn, providing excellent abrasion resistance. The inclusion of a second yarn made of nylon (or polyester) and polyurethane gives the fabric excellent compactness and elasticity. This makes the fabric wrinkle-resistant and durable. The abrasion resistance (number of frictions to break) of the fabric provided by this invention has been confirmed to be approximately 785 to 8,832 times.

[0043] Figure 1 is a knitting diagram of an example of a knitted fabric provided by the present invention. This Figure 1 shows how multiple knitting needles provided in a circular knitting double-sided machine that knits the knitted fabric relate to each of the yarns supplied from multiple yarn feeders provided in the circular knitting double-sided machine. Note that this Figure 1 only shows one example of a knitted fabric according to the present invention, and does not limit the knitting of the knitted fabric provided by the present invention to the structure shown in this figure.

[0044] A circular knitting double-sided machine is provided with multiple yarn feeders, and in Figure 1, four yarn feeders are assigned to one knitting unit of the knitted fabric. Each of the four yarn feeders is assigned to two first yarns (3, 4) and two second yarns (1, 2), with the ratio of the yarn feeders for the first yarns to the yarn feeders for the second yarns being 2:2. As a result, the knitted fabric is knitted using two first yarns and two second yarns as one knitting cycle (one knitting unit).

[0045] A double-sided circular knitting machine comprises a cylindrical lower needle barrel (cylinder) and a disk-shaped upper needle disk (dial) placed above the lower needle barrel. Multiple knitting needles are arranged in a circular pattern (circumferentially) on each of the lower needle barrel and upper needle disk, and these knitting needles knit both sides of the fabric into a cylindrical shape. The multiple knitting needles on the lower needle barrel are arranged so that they move up and down in the vertical direction along the outer circumferential surface of the cylinder. The multiple knitting needles on the upper needle disk are arranged so that they move back and forth in the radial direction along the top surface of the disk. In Figure 1, the knitting needles shown above the yarns (1, 2, 3, 4) at each yarn feeder are the knitting needles on the upper needle disk, and the knitting needles shown below the yarns at each yarn feeder are the knitting needles on the lower needle barrel.

[0046] In Figure 1, the lower needle barrel and the upper needle board are shown as having high and low knitting needles arranged alternately. In Figure 1, the long ones are the high needles (high needle DH on the lower needle barrel and high needle UH on the upper needle board), and the short ones are the low needles (low needle DL on the lower needle barrel and low needle UL on the upper needle board). The low needle DL on the lower needle barrel faces the high needle UH on the upper needle board, and the high needle DH on the lower needle barrel faces the low needle UL on the upper needle board.

[0047] As shown in Figure 1, during the knitting process of a knitted fabric, one of the two second yarns (1) forms a stitch (loop) with the low needle DL of the lower needle barrel and the low needle UL of the upper needle board, and the other second yarn (2) forms a stitch with the high needle DH of the lower needle barrel and the high needle UH of the upper needle board.

[0048] One of the two first yarns (3) forms a stitch with the high needle DH of the lower needle barrel and the low needle DL of the lower needle barrel, and the other first yarn (4) forms a stitch with the high needle UH of the upper needle board and the low needle UL of the upper needle board.

[0049] As a result, one of the two first yarns (3) is knitted with a lower needle using the lower needle cylinder, and the other first yarn (4) is knitted with an upper needle using the upper needle board, forming a loop structure with the first yarn (for example, Cordura yarn) on both the front and back sides of the fabric (the sides facing the outside).Then, the two second yarns (1, 2) are knitted with both the upper needle board and the lower needle cylinder, respectively, connecting both the front and back sides of the fabric to form a fabric with a ponte roma structure.

[0050] Figure 2 is a diagram showing the relationship between each needle and each yarn of the circular knitting double-faced machine that knits the knit fabric of Figure 1. This Figure 2 shows, in a different way from Figure 1, how the multiple knitting needles provided on the circular knitting double-faced machine relate to each of the yarns supplied from the multiple yarn feeders provided on the circular knitting double-faced machine.

[0051] In Figure 2, each square represents a combination of multiple yarns and a knitting needle. A horizontal line (-) indicates that the combination will not form a stitch (miss). A downward-pointing triangle (∨) indicates that the knitting needle on the upper needle table will form a stitch (knit). An upward-pointing triangle (∧) indicates that the knitting needle on the lower needle table will form a stitch (knit).

[0052] As with Figure 1, Figure 2 also shows the relationship between each yarn and each needle during the knitting process of knitted fabric as follows: One of the two second yarns (1) forms a stitch by the lower needle DL of the lower needle barrel and the lower needle UL of the upper needle board. The other second yarn (2) forms stitches using the high needle DH of the lower needle barrel and the high needle UH of the upper needle board. One of the two first yarns (3) forms stitches with the high needle DH of the lower needle barrel and the low needle DL of the lower needle barrel. The other first yarn (4) forms stitches with the high needle UH on the upper needle board and the low needle UL on the upper needle board.

[0053] In other words, for the stitches of the first yarn (for example, Cordura yarn), one of the two first yarns (3) winds a loop (stitch) on the lower needle barrel, does not wind a loop on the upper needle board, and is placed on the front side (one side) of the fabric. The other first yarn (4) winds a loop on the upper needle board, does not wind a loop on the lower needle barrel, and is placed on the back side (the other side) of the fabric.

[0054] As described above, by using a circular knitting double-sided machine in which the ratio of yarn feeders allocated to the first yarn (e.g., Cordura yarn) and the second yarn (composite yarn) is 2:2, a fabric with a ponte roma structure can be knitted in which two first yarns (e.g., Cordura yarn) and two second yarns (composite yarn) form one knitting cycle (one knitting unit).

[0055] Figure 3 is a diagram showing the structure of the second yarn (1, 2) included in the knit fabric of Figure 1. As shown in Figure 3, the second yarn is a composite yarn (covered yarn) having an outer layer 5 and an inner layer 6. The outer layer 5 of the second yarn is a nylon yarn or a polyester yarn, and the inner layer 6 is a polyurethane yarn.

[0056] Figure 4 is a diagram showing the structure of the knit fabric of Figure 1. Figure 4 shows that a first yarn, which is a highly abrasion-resistant nylon or polyester yarn, such as CORDURA yarn, is arranged on the front surface (one side) and back surface (the other side) of the fabric. Also shown is that two second yarns (1, 2), which are composite yarns, are interwoven with the first yarn on the front surface (one side) and back surface (the other side) of the fabric, respectively. [Example]

[0057] The present invention will be explained in more detail below with reference to examples, but the present invention is not limited to these examples.

[0058] [Example 1] This example provides an example of a knitted fabric for cut-and-sew applications that is abrasion-resistant and tightly elastic. This fabric has a pontillomania structure (knitted structure) in which two CORDURA yarns as the first yarn and two composite yarns (covered yarns) as the second yarn are knitted in one knitting cycle. The outer layer of the composite yarns (outer layer) is nylon yarn, and the inner layer is polyurethane yarn.

[0059] Here, CORDURA yarn is a CORDURA blended staple yarn made by blending CORDURA nylon staple fiber with cotton fiber, with the nylon staple fiber accounting for about 40% of the total weight of the yarn and the cotton fiber accounting for about 60% of the total weight of the yarn. The thickness of the CORDURA blended staple fiber yarn is 32 / 1 in English count. The composite yarn is a covered yarn made of nylon and polyurethane, with the nylon being the outer layer of the composite yarn and the polyurethane yarn being the inner layer of the composite yarn. The thickness of the nylon yarn is 70D and the thickness of the polyurethane yarn is 20D. The fabric weight is 295g / m 2 and the fabric width is 165cm.

This fabric has a ponte roman weave structure, knitted in one knitting cycle using two CORDURA yarns as the first yarn and two composite yarns as the second yarn. The outer layer of the composite yarn is polyester yarn, and the inner layer is polyurethane yarn.

[0061] Here, CORDURA yarn is a CORDURA blended staple yarn made by blending CORDURA nylon staple fiber with cotton fiber, with the nylon staple fiber accounting for about 40% of the total weight of the yarn and the cotton fiber accounting for about 60% of the total weight of the yarn. The thickness of the CORDURA blended staple fiber yarn is 32 / 1 in English count. The composite yarn is a covering yarn of polyester and polyurethane, with the polyester yarn being the outer layer of the composite yarn and the polyurethane yarn being the inner layer of the composite yarn. The thickness of the polyester yarn is 75D and the thickness of the polyurethane yarn is 20D. The fabric weight is 270g / m 2 and the fabric width is 165cm.

[0062] [Example 3] This example provides an example of a knitted fabric for cut-and-sew applications that is abrasion-resistant and tightly elastic. This fabric has a ponte roman weave structure, knitted in one knitting cycle using two CORDURA yarns as the first yarn and two composite yarns as the second yarn. The outer layer of the composite yarn is polyester yarn, and the inner layer is polyurethane yarn.

[0063] Here, CORDURA yarn is a nylon filament yarn made from CORDURA nylon filaments, and the thickness of the nylon filament yarn is 70D. The composite yarn is a covering yarn of nylon and polyurethane, with the nylon yarn being the outer layer of the composite yarn and the polyurethane yarn being the inner layer of the composite yarn. The thickness of the nylon yarn is 70D, and the thickness of the polyurethane yarn is 20D. The fabric weight is 273g / m 2 and the fabric width is 165cm.

[0064] [Comparative Example 1] This comparative example provides an example of a knitted fabric for cut and sew. This fabric is knitted with a composite yarn, which is a covering yarn of nylon yarn and polyurethane yarn. The nylon yarn is the outer layer of the composite yarn, and the polyurethane yarn is the inner layer of the composite yarn. The thickness of the nylon yarn is 70D, and the thickness of the polyurethane yarn is 30D. The fabric weight is 280g / m 2 and the fabric width is 165cm.

[0065] [Comparative Example 2] This comparative example provides an example of a knit fabric for cut and sew. This fabric includes outer layer loops and inner layer loops, which together form a plain knit structure. The outer layer loops are knitted with Cordura yarn, and the inner layer loops are knitted with polyurethane yarn. The loop length of the Cordura yarn is 25.5 cm / 100 needles, and the loop length of the polyurethane yarn is 9.0 cm / 100 needles. The Cordura yarn is a blend of Cordura fiber (nylon fiber) and cotton fiber at a ratio of 32 / 1, and the fabric has a basis weight of 165 g / m 2 is.

[0066] [Performance test] Abrasion resistance tests were conducted on the fabrics provided in Examples 1-3 and Comparative Examples 1-2. This test was based on the A-1 method (plane method) specified in JIS L 1096 (JIS: Japanese Industrial Standards), and the number of times the test fabric was rubbed until it broke was measured using an RT-300 abrasion machine. The test conditions were a pressing load of 4.45 N and abrasive paper type P1200C-CW.

[0067] The specific test results are shown in Table 1 below.

[0068] [Table 1]

[0069] As can be seen from the test data in Table 1, the number of abrasion cycles until failure of the fabric provided by this invention is approximately 785 to 8,832. The surface of the fabric is made up of CORDURA yarn as the first thread, which has been confirmed to have excellent abrasion resistance. In addition, the composite yarn as the second thread, which is made up of nylon yarn and polyurethane yarn, gives the fabric excellent tightness and elasticity, making it wrinkle-resistant and sturdy (durable), and it has a wide range of applications.

[0070] The above are merely illustrative of specific embodiments and examples of the present invention, and the scope of protection of the present utility model is not limited thereto. Those skilled in the art should consider that any changes or substitutions that are easily conceivable within the technical scope described in this specification are also within the scope of protection and disclosure of the present utility model.
