Description

Technical Field

[0001] The present invention relates to the technical field of knitted collar processing. Specifically, it relates to a flat knitting machine knitted collar that has excellent wash resistance, does not curl, and has high shape retention, and a manufacturing method thereof.

Background Art

[0002] The most intuitive requirements for knitted collars from consumers mainly include that when worn, comfort when touching the neck is required, and it is required that the collar can maintain a flat and flexible state over a long period of time. That is, after multiple washes, it still has good form stability and no obvious curling and wrinkles occur. However, the collars of knitted shirts currently on the market often have problems such as curling, corner warping, and discomfort when worn after multiple washes, which affect the aesthetics of clothing and shorten the service life. A commonly used improvement method is to add spandex, but after multiple washes, problems such as elastic loss and obvious deformation of spandex occur.

[0003] The prior art with publication number CN201910847262.4 discloses a flat knitting machine knitted collar that has excellent wash resistance, high elasticity and high shape retention, a manufacturing method thereof, and an application. The flat knitting machine knitted collar that has excellent wash resistance, high elasticity and high shape retention has a two-layer tissue structure with a dense needle distance. The front and back surfaces of the flat knitting machine knitted collar are woven with long pile cotton yarn and high-elasticity polyester yarn, and the front and back surfaces are connected by elastic spandex yarn. In this collar, spandex is used as a connecting thread to connect the front and back tissues, but in the process of multiple washes, problems such as elastic loss and obvious deformation of spandex are still likely to occur.

Summary of the Invention

Problems to be Solved by the Invention

[0004] In view of this, the object of the present invention is to provide a knitted collar made on a flat knitting machine that has excellent wash resistance, does not curl, and has high shape retention, and a method for manufacturing the same. In conventional collars, spandex is used as a connecting yarn to connect the front and back layers, but problems such as loss of elasticity and obvious deformation of the spandex still tend to occur during the process of multiple washes. [Means for solving the problem]

[0005] To achieve the above objective, the technical proposal of the present invention is implemented as follows.

[0006] The knitted collar is made on a flat knitting machine and has excellent washability, does not curl, and has high shape retention. The knitted collar includes a collar body and three plain edges that are connected to each other. The structure of the collar body is a rib plating structure. The plain edges of the three sides include a left plain edge, a right plain edge, and an upper plain edge. The left side of the collar body is connected to the left plain edge, the right side of the collar body is connected to the right plain edge, and the upper end of the collar body is connected to the upper plain edge. Both the collar body and the plain edges of the three sides are knitted with face yarn and ground yarn. The face yarn is a polyester / cellulose fiber blend staple yarn, and the ground yarn is knitted with polyester filament yarn. The single filament fineness of the polyester filament yarn is 100-200D, and the single filament fineness of the polyester / cellulose fiber blend staple yarn is 30-50S.

[0007] In this design, the collar body has a rib structure, which has relatively good elasticity and recovery properties, effectively resisting external forces during the washing process and reducing collar deformation. The knitted collar, made by combining polyester filament yarn and polyester / cellulose fiber blended short fiber yarn, is not only comfortable to wear but also does not curl or curl at the corners after multiple washes, improving the aesthetic appearance of the garment. The collar body is connected to the plain edges of three surfaces, effectively resisting external forces during the washing process, reducing collar deformation, and ensuring that the collar does not curl. Furthermore, the knitted collar, made by knitting with polyester filament yarn and polyester / cellulose fiber blended short fiber yarn, not only provides the knitted collar with excellent flexibility, resilience, and wrinkle resistance but also enhances the collar's shape retention. Furthermore, by controlling the single filament fineness of the polyester filament yarn to 100-200D, the ground yarn of such fineness can provide sufficient support while also maintaining the flexibility of the collar.

[0008] Furthermore, the number of strands twisted in the above-mentioned polyester filament yarn is 1 to 2, and the number of strands twisted in the above-mentioned polyester / cellulose fiber blended staple yarn is 3 to 5.

[0009] The number of twists in the polyester filament yarn and the ester / cellulose fiber blended staple yarn in this setup significantly affects the shape retention, size stability, water resistance, and flexibility of the knitted collar. For example, increasing the number of twists in the yarn increases the breaking strength and tear strength of the fabric and improves the overall shape retention of the knitted collar. However, if the number of twists is too high, the fabric structure becomes tighter, increasing the friction between fibers. As a result, the fabric feels harder to the touch and its flexibility decreases. Therefore, the number of twists in this setup is preferable.

[0010] Furthermore, the above-mentioned polyester / cellulose fiber blended staple yarn is one of the following: polyester fiber and cotton, polyester fiber and viscose fiber, polyester fiber and lyocell fiber, or polyester fiber and modal fiber.

[0011] The cotton, viscose, lyocell, and modal fibers used in this installation possess relatively good flexibility, comfort, moisture absorption, and breathability. When blended with polyester fibers and knitted on a flat knitting machine, the resulting collars are not only comfortable to wear but also highly water-resistant, retaining their rich luster and vibrancy even after multiple washes.

[0012] Furthermore, the above-mentioned polyester / cellulose fiber blended staple yarn is manufactured using a vortex spinning or silo-compact spinning process.

[0013] The knitted collars produced by this installation have less fuzz, uniform strands, and good abrasion and pilling resistance. The yarn possesses the relatively good strength and rigidity of polyester, while maintaining the comfort and flexibility of cellulose fibers. At the same time, the polyester filament yarn used as plating significantly improves the collar's shape retention, making it less prone to curling.

[0014] Furthermore, the machine used to knit the collar described above is a flat knitting machine.

[0015] Furthermore, the loop length of the face yarn of the collar body is 36-45 cm / 50 stitches, and the loop length of the ground yarn of the collar body is 34-40 cm / 50 stitches.

[0016] Furthermore, the gram weight of the knitted collar on the above flat knitting machine is 650-750g / m 2 That is the case.

[0017] Furthermore, the width of the collar body is W1, and the width of the upper plain edge is W2, so W1 > W2.

[0018] This installation maintains the aesthetic appeal of the knitted collar and provides it with relatively good shape retention.

[0019] Furthermore, the weight ratio of polyester to cellulose fiber in the above-mentioned polyester / cellulose fiber blended short fiber yarn is 50-80:50-20.

[0020] The setting is controlled such that the content of polyester fiber occupies the range of 50% - 80%, ensuring that it can still maintain stable performance after being washed multiple times. At the same time, the fineness and softness of the warp knitting collar are also guaranteed, thereby making the wearing more comfortable.

[0021] Furthermore, the left plane edge and the right plane edge have the same knitting structure, and both are knitted on the back needle bed at the same time, alternately increasing and decreasing one knitting needle on both sides every other course.

[0022] Furthermore, the upper plane edge is composed of a knitting outlet and a cylinder. The knitting outlet is a rib plating structure. Before the first course, the front and back needle beds alternately extend needles every other needle to form loops. The cylinder is formed by repeating the front and back needle beds 3 - 5 times each to knit a plain weave structure. The loop length of the knitting outlet is 34.5 - 38 cm / 50 needles, and the loop length of the cylinder is 22 - 26 cm / 50 needles.

[0023] A manufacturing method of a warp knitting collar that is used for manufacturing the above - mentioned warp knitting collar, has excellent washability, does not curl, and has high shape - retention property, including the following steps, namely, S1. Knitting of the warp knitting collar, S2. Functional finishing, S3. Fleece finishing.

[0024] Furthermore, the process parameters of the fleece finishing are that the finishing time is 5 - 8 min and the temperature is 100 - 115 °C.

[0025] Furthermore, step S2 includes the following steps, namely, S21. Pretreatment, S22. Anti - wrinkle liquid finishing, S23. Squeezing and drying with water, S24. Anti - shrinkage finishing.

[0026] Furthermore, regarding the specific process parameters of the pretreatment, the horizontal knitting machine knitted collar is fixed in shape by high-temperature steam at 180 to 190 °C, and the shape fixation time is 10 to 15 minutes.

[0027] Furthermore, regarding the specific process parameters of hydroextractor drying, the horizontal knitting machine knitted collar is dried by a hydroextractor so that the moisture content becomes 25 to 35%, and the drying temperature is 75 to 85 °C.

[0028] Furthermore, regarding the specific process parameters of shrink-proof finishing, it is carried out by a shrink-proof machine, the temperature of the rubber blanket is 100 °C, and the temperature of the wool blanket is 110 °C.

Advantages of the Invention

[0029] Compared with the prior art, the horizontal knitting machine knitted collar with excellent washability, no curling, and high shape retention described in the present invention and its manufacturing method have the following advantages.

[0030] 1) The collar body of the present invention has a plating rib tissue structure. Such a tissue has relatively good elasticity and resilience, can effectively resist the external force during the washing process, reduce the deformation of the collar, and this tissue structure, combined with polyester long fiber yarn and polyester / cellulose fiber blended short fiber yarn, the horizontal knitting machine knitted collar knitted is not only comfortable to wear, but also does not curl or the corners do not turn up after multiple water washes, improving the aesthetic degree of clothing use. Moreover, the collar body is connected to the plane edges of three sides, can effectively resist the external force during the washing process, reduce the deformation of the collar, and ensure that no curling occurs on the collar.

[0031] 2) The horizontal knitting machine knitted collar of the present invention is knitted from polyester long fiber yarn and polyester / cellulose fiber blended short fiber yarn, which not only gives the horizontal knitting machine knitted collar excellent flexibility, rebound resilience, and wrinkle resistance, but also enhances the shape retention of the collar. In addition, the single filament fineness of the polyester long fiber yarn is controlled to be 100 to 200 D. The ground yarn with such a fineness can provide sufficient support force and also maintain the flexibility of the collar.

[0032] 3) The present invention is advantageous in reducing the burden on the yarn at the collar edge, maintaining the flatness of the collar, and reducing frayed edges by alternately increasing or decreasing the number of knitting needles on the left and right plain edges. Furthermore, by having a different structural design for the upper plain edge from the collar body, it is advantageous in maintaining the overall stability of the collar and avoiding problems such as curling and corners bending upwards.

[0033] 4) The knitted collar of the present invention has excellent shape retention and fold recovery properties. After multiple washes, the corners of the collar do not curl up or become distorted, and the entire collar retains its shape, making it comfortable to wear and gentle on the skin.

[0036] To make the above-mentioned objectives, features, and advantages of the present invention clearer and easier to understand, specific embodiments of the present invention will be described in detail below with reference to the drawings. Furthermore, the directions mentioned in the following specific embodiments will be briefly explained, and the directions or positional relationships indicated by "up," "down," "left," and "right" mentioned in the embodiments refer to the directions or positional relationships shown in the drawings.

[0037] Example 1 The present invention relates to a flat knitted collar that is highly washable, does not curl, and has high shape retention. The flat knitted collar is knitted on a flat knitting machine and includes a collar body A and three plain edges of three sides that are connected to each other. The plain edges of the three sides include a left plain edge B2, a right plain edge B3, and an upper plain edge B1. The left side of the collar body is connected to the left plain edge, the right side of the collar body is connected to the right plain edge, and the upper end of the collar body is connected to the upper plain edge. Both the collar body and the plain edges of the three sides are knitted with face yarn and ground yarn. The face yarn is a blend of polyester fibers and viscose fibers (abbreviated as polyester / viscose blend yarn), and the ground yarn is a polyester filament yarn.

[0038] In this design, the collar body is connected to the plain edges of three surfaces, effectively resisting external forces during the washing process, reducing collar deformation, and ensuring that the collar does not curl. Furthermore, the knitted collar is made from polyester filament yarn and polyester / viscose fiber blended staple yarn, providing the knitted collar with excellent flexibility, resilience, and wrinkle resistance, as well as further enhancing the collar's shape retention. In addition, the single filament fineness of the polyester filament yarn is controlled to 100-200D, and such fineness ground yarns can provide sufficient support while maintaining the collar's flexibility.

[0039] Preferably, the weight ratio of polyester to viscose in the polyester / viscose blended yarn was 80:20. In the collar body, the overall polyester content was high, and due to its good rigidity, softness, wrinkle resistance, and abrasion resistance, the collar maintained its shape well, and the collar shape was not easily destroyed after washing. Due to the moisture absorption and quick-drying properties of polyester and the flexibility and moisture absorption of viscose, the collar provided good comfort, ensuring comfort for the neck. The collar shape was not easily destroyed after washing, and after 30 washes, the collar did not deform, did not curl, had good rebound elasticity, and both colorfastness and pilling resistance were grade 4 or higher.

[0040] Specifically, the above-mentioned polyester filament yarn had a single filament fineness of 100D and a twist count of 2 strands, while the above-mentioned polyester / viscose blended yarn had a single filament fineness of 30S and a twist count of 2 strands.

[0041] Specifically, the collar body described above has a plating rib structure, and was knitted on a flat knitting machine with a needle distance of 16 needles, and the specific knitting process was as follows.

[0042] The collar body described above was knitted using a full loop formation method, with polyester filament yarn and polyester / viscose blend yarn supplied synchronously by a plating method. The length of the face yarn was 40.5 m / 50 stitches, and the length of the ground yarn was 37 cm / 50 stitches.

[0043] Specifically, the upper plain edge B1 described above consisted of a knitting opening and a cylinder, and the specific knitting process for the upper plain edge was as follows.

[0044] As shown in Figure 4, in the first course, polyester filament yarn and polyester / viscose blend yarn were supplied synchronously by a plating method, and the front and back needle beds alternately fed needles, knitting in a loop-forming manner. This knitting formed a knitting starter, and the length of the loop at the knitting starter was 34 cm / 50 needles.

[0045] As shown in Figure 5, in the second course, polyester filament yarn and polyester / viscose blend yarn are supplied synchronously using a plating method, the front needle bed does not knit, and all the needles on the back needle bed employ loop forming knitting.

[0046] As shown in Figure 6, in the third course, polyester filament yarn and polyester / viscose blend yarn were supplied synchronously using a plating method, the rear needle bed did not knit, and all the needles on the front needle bed employed loop-forming knitting. The second and third courses were repeated alternately three times to form a cylinder, and the length of the loops of the knitted cylinder was 22 cm / 50 needles.

[0047] Specifically, the left plain edge B2 and the right plain edge B3 described above have the same knitting structure, and both were knitted simultaneously on the back needle bed, with one knitting needle being added or removed alternately on both sides every other course.

[0048] More specifically, the minimum repeating knitting structure of the left plain edge described above consists of two courses, where the outermost needles of the first course all emerge from the front needle bed to form a loop, and the outermost needles of the second course all emerge from the back needle bed to form a loop, and when the two courses, the second course and the first course, alternate, the back needle bed at the outermost end needs to alternately increase or decrease by one needle.

[0049] This configuration allows the rib structure of the collar body to restrain the rib structure of the knitting opening, and the knitting structure of the knitting opening and the cylinder to restrain the main body structure. At the same time, the needle tension adjustment of the plain edges on the left and right reduces the burden on the yarn at the collar edge, which is advantageous in preventing the edge from fraying. As a result, the entire knitted collar does not deform, has excellent wash resistance and stability, does not scatter after washing, and is less prone to waviness.

[0050] Specifically, the above-mentioned upper plain edge B1 is connected to the collar body, and the above-mentioned upper plain edge B1 consists of a knitting opening and a cylinder, the above-mentioned knitting opening is a rib plating structure, in which the front and back needle beds of the first course alternately bring out needles every other stitch to form loops, and the cylinder is made by knitting a plain weave structure by repeating the front and back needle beds 3 to 5 times each, the length of the loops of the above-mentioned knitting opening was 34.5 to 38 cm / 50 needles, and the length of the loops of the above-mentioned cylinder was 22 to 26 cm / 50 needles.

[0051] In this installation, the collar, with its three-sided plain edge design, has relatively good elasticity and resilience, which helps resist external forces during the washing process, reduces deformation, maintains the flatness and stability of the collar, and is advantageous in avoiding problems such as curling and corner warping.

[0052] Specifically, the above polyester / viscose blend yarn was manufactured using a vortex spinning process.

[0053] Specifically, the width of the collar body was W1, and the width of the upper plain edge was W2, with W1 > W2.

[0055] Preferably, the weight ratio of polyester to lyocell in the polyester / viscose blended yarn was 60:40.

[0060] As shown in Figure 4, in the first course, polyester filament yarn and polyester / lyocell blend yarn were supplied synchronously by a plating method, and the front and back needle beds alternately fed needles, knitting in a loop-forming manner.

[0100] Comparative Example 4 The difference between this comparative example and Example 5 is that a fleece finish is not applied.

[0101] Performance detection test Flat knitted collars were manufactured using Examples 1-6 and Comparative Examples 1-4. After washing the samples 30 times, the following performance detection experiments were conducted, and three monitoring data points were measured and their average values ​​were taken.

[0102] 1. Wrinkle recovery angle test Following the AATCC 66-2006 standard, the samples were washed 30 times with water, and then tested. The wrinkle recovery angle was recorded for both the examples and comparative examples.

[0103] 2. Flatness of the exterior Following the drum drying procedure specified in ISO 77685A, the samples were washed 30 times with water, then detected. The overall appearance level (grade) of the samples in the examples and comparative examples was recorded, with the standard being ≥3.5.

[0104] III. Size Stability Test Following the experimental home washing and drying procedures in GB / T 8629, samples were washed 30 times and then detected. The percentage change in vertical size and horizontal size of the samples in the examples and comparative examples was recorded.

[0105] Detection results: The detection results for the samples prepared in Examples 1-6 and Comparative Examples 1-4 are shown in Table 1. [Table 1]

[0106] By comparing Comparative Example 1 and Example 2, the present invention ensures that the collar body, by being connected to the plain edges of three surfaces, effectively resists external forces during the washing process, reduces collar deformation, and prevents curling of the collar. A comparison of Comparative Examples 2-4 and Example 5 demonstrates that the knitted collar obtained in the present invention has excellent wrinkle resistance, flatness, and size stability.

[0107] Although the present invention is disclosed as described above, it is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the invention, and therefore the claims of the present invention are equivalent to those limited to the patent claims.
