Description

Technical Field

[0001] The present invention relates to a comfortable and shaped knitted sportswear, belonging to the field of clothing. Background Art

[0002] A knitted fabric is formed by loops, tucks and floats. A loop is the basic coil of knitting. During weft knitting, a yarn is sequentially laid on each knitting needle in a looping mechanism, and each knitting needle forms a loop in sequence or simultaneously, forming a row of loops in the weft direction. And each loop in this row is strung with the corresponding loop of the previous row, so that the rows are connected to each other, realizing the stringing connection in the horizontal and vertical directions. A tuck is to push one or two diagonal presser cams in the weft knitting machine to a certain height. When the machine head drives the cams to run, the knitting needle rises to the highest point and then descends to the closed position and no longer descends. The loop closes the latch and hangs on the needle bar. At this time, the hook of the needle hooks the newly laid yarn; when the machine head runs in the reverse direction to knit the next row, the knitting needle can rise to the apex or descend to the lowest point under the action of the cams. After the new yarn forms a floating arc and retreats the loop, it merges with the old loop hanging on the needle bar and they are jointly cast off to form a tuck. The loop is stretched to form a breathable mesh, and the floating arc realizes the diagonal connection and stringing of adjacent loops. Float: During weft knitting, when some knitting needles do not participate in knitting after passing through one or several paths and then participate in knitting again, the old loops will pass through the yarns that did not participate in knitting and are threaded with the new loops. These unformed yarns form floats behind the old loops, which can reduce the lateral extensibility in the weft direction and improve the dimensional stability, but they cannot be too long, otherwise they are easy to snag.

[0003] Knitted sportswear mainly includes knitted pullover sweatshirts, knitted zip-up shirts and knitted trousers. It has both a certain degree of warmth retention and good air permeability, and is suitable for wearing in spring and autumn seasons when the temperature is about 10-20 °C, and is deeply loved by the majority of consumers. At present in the market, the mainstream spring and autumn knitted sportswear sets mainly adopt the following solutions to achieve:

[0004] (1) The first generation of wire cloth and air layer: the surface layer and the inner layer are both plain weave, generally using 26S-40S combed cotton, and the middle binding yarn layer generally uses 75D-150D polyester yarn, forming a cotton-polyester structure, or one layer uses 26S-40S combed cotton, the other layer uses 50-100D polyester yarn, and the binding yarn layer uses 75-150D polyester yarn, forming a cotton-polyester-polyester structure. The advantage is that at least one side is cotton, and the surface layer is cotton. The feeling is of high grade, the inner layer is soft and skin-friendly, the cost is low, thick, warm and crisp, and it is currently the most widely used; 50-100D polyester yarn is used for the surface and inner layer, and 75-150D polyester yarn is used for the binding yarn layer to form a polyester-polyester structure. The advantages are that the surface and inner layer are both made of polyester, which is cheap, thick, warm, crisp, stylish and does not pill. The disadvantages are that the chemical fiber feeling is of low grade, the skin-friendliness is not good, and it is uncomfortable to wear close to the body. It is currently less used.

[0005] In order to achieve a crisp hand feel, thick warmth, the above-mentioned fabrics have plain weave on the front and back layers, and the binding yarn is connected to the front and back layers with a double-sided rib structure through coarser polyester yarn. The front layer, the back layer and the binding yarn layer are all connected by loops, which are connected horizontally and vertically, just like a quadrilateral. They are easily deformed in the oblique direction, and have poor ductility and recovery. They are prone to arching and deformation when worn, and are easily deformed when washed, so the clothes are not durable.

[0006] (2) Second generation wire cloth, air layer:

[0007] The second generation of wire cloth and air layer fabric improves the performance of the fabric by changing the binding yarn and the structure.

[0008] Change the binding yarn: the inner layer can be 26-40S combed cotton or 50-100D polyester yarn, and the binding yarn can be made of 20-70D spandex to form a spandex sandwich structure. The spandex is connected to the inner layer in the form of double-sided ribbing, which can obtain good elasticity and will not deform or bulge when worn and washed. However, due to the strong contraction of spandex, the structure is very tight, the binding yarn layer is very thin, the fluffiness is not enough, it is not thick enough, and the warmth retention is poor.

[0009] Change the structure: Since the most representative of the tucked loop structures is the pearl structure, which is a concave and convex structure woven by loops and tucked loops according to a certain pattern, the fabric surface is mesh-like. Compared with the knitted plain weave, it feels drier and crisper, and is more stylish to wear. At the same time, it is more breathable and moisture-permeable, has better heat dissipation, and is cooler to wear. However, it feels rough and has poor skin-friendliness. Therefore, the surface layer can only be changed from plain weave to pearl structure, and the lining layer remains plain weave. Although it can improve the technical difficulties of the first-generation silk cloth and the air layer that are easy to arch and deform, the surface layer feels too rough, and the problems of arching and deformation still exist.

[0010] In view of this, the inventor conducted in-depth research on the above-mentioned issues, and thus the present case was produced. Summary of the Invention

[0011] The object of the present invention is to provide a knitted sportswear with good comfort, warmth retention and shape retention properties.

[0012] To achieve the above object, the present invention adopts the following technical solution:

[0013] A comfortable and shaped knitted sportswear, comprising a garment body spliced by knitted fabrics. The knitted fabric includes a surface layer, a lining layer integrally woven by a double-sided circular knitting machine, and a binding yarn layer for connecting the surface layer and the lining layer. The surface layer is interwoven by face yarns, the lining layer is interwoven by bottom yarns, and the binding yarn layer is interwoven by binding yarns. The surface layer includes alternately arranged first plain weave areas and first piqué areas. The first plain weave areas are interwoven by 40S / 1 cotton yarns in a plain weave knitting method, and the first piqué areas are interwoven by 100D / 36F polyester yarns in a piqué knitting method. The binding yarn is 100D / 36F polyester yarn. The lining layer includes alternately arranged second plain weave areas and second piqué areas. The second plain weave areas are interwoven by 32S / 1 cotton yarns in a plain weave knitting method, and the second piqué areas are interwoven by 100D / 36F polyester yarns in a piqué knitting method.

[0014] As a preferred embodiment of the present invention, the area ratio of the first plain weave area to the first piqué area is 3:1, and the area ratio of the second plain weave area to the second piqué area is 3:1.

[0015] As a preferred embodiment of the present invention, the double-sided circular knitting machine takes 48 courses as a large cycle. A large cycle is divided into four medium cycles, each medium cycle consists of 12 courses. Each medium cycle is divided into four small cycles, each small cycle consists of 3 courses. The 1st to 12th courses form the first medium cycle, the 13th to 24th courses form the second medium cycle, the 25th to 36th courses form the third medium cycle, and the 37th to 48th courses form the fourth medium cycle.

[0016] In the first medium cycle: In each small cycle, in one course, the top cylinder knits the bottom yarn and the bottom cylinder does not knit; in another course, the bottom cylinder knits the face yarn and the top cylinder knits; in another course, the top cylinder and the bottom cylinder alternately knit the binding yarn to form a 1+1 rib structure. In the first three small cycles, the face yarn uses 40S / 1 cotton yarn, the bottom yarn uses 32S / 1 cotton yarn, and the binding yarn uses 100D / 36F polyester yarn. In the fourth small cycle, the face yarn, the bottom yarn and the binding yarn all use 100D / 36F polyester yarn.

[0017] In the second middle loop: In the first three small loops, in each small loop, on one path, the top dial knits the bottom yarn, the bottom dial does not knit, on another path, the bottom dial knits the face yarn, the top dial knits, and on yet another path, the top dial and the bottom dial alternately knit the binding yarn to form a 1+1 rib stitch. In the first three small loops, the face yarn uses 40S / 1 cotton yarn, the bottom yarn uses 32S / 1 cotton yarn, and the binding yarn uses 100D / 36F polyester yarn; In the fourth small loop, on one path, the knitting of the bottom dial alternately knits the face yarn in the ways of forming loops and tucking, the top dial does not knit, on another path, the knitting of the top dial alternately knits the bottom yarn in the ways of forming loops and tucking, the bottom dial does not knit, and on yet another path, the top dial and the bottom dial alternately knit the binding yarn to form a 1+1 rib stitch. In the fourth small loop, the face yarn, the bottom yarn, and the binding yarn all use 100D / 36F polyester yarn;

[0018] In the third middle loop: In each small loop, on one path, the top dial knits the bottom yarn, the bottom dial does not knit, on another path, the bottom dial knits the face yarn, the top dial knits, and on yet another path, the top dial and the bottom dial alternately knit the binding yarn to form a 1+1 rib stitch. In the first three small loops, the face yarn uses 40S / 1 cotton yarn, the bottom yarn uses 32S / 1 cotton yarn, and the binding yarn uses 100D / 36F polyester yarn. In the fourth small loop, the face yarn, the bottom yarn, and the binding yarn all use 100D / 36F polyester yarn;

[0019] In the fourth middle loop: In the first three small loops, in each small loop, on one path, the top dial knits the bottom yarn, the bottom dial does not knit, on another path, the bottom dial knits the face yarn, the top dial knits, and on yet another path, the top dial and the bottom dial alternately knit the binding yarn to form a 1+1 rib stitch. In the first three small loops, the face yarn uses 40S / 1 cotton yarn, the bottom yarn uses 32S / 1 cotton yarn, and the binding yarn uses 100D / 36F polyester yarn; In the fourth small loop, on one path, the knitting of the bottom dial alternately knits the face yarn in the ways of tucking and forming loops, the top dial does not knit, on another path, the knitting of the top dial alternately knits the bottom yarn in the ways of tucking and forming loops, the bottom dial does not knit, and on yet another path, the top dial and the bottom dial alternately knit the binding yarn to form a 1+1 rib stitch. In the fourth small loop, the face yarn, the bottom yarn, and the binding yarn all use 100D / 36F polyester yarn.

[0020] By adopting the technical solution of the present invention, the advantages of plain weft and piqué textures are complemented in terms of structure, significantly enhancing the shape retention of the surface layer and the inner layer. A small piqué effect with an inconspicuous concave-convex feeling is formed on the front, and the front feels soft and delicate like plain weft. A small piqué effect with almost no concave-convex feeling is formed on the back, making the inner layer feel as soft and delicate as plain weft, being very skin-friendly when worn close to the body, improving the technical problems of obvious concave-convex feeling and too rough hand feeling of ordinary piqué, and realizing the complementary advantages of plain weft and piqué; in terms of materials, the advantages of cotton and polyester are complemented. At the same time, a relatively thick binding yarn layer can be had, making the fabric very thick, capable of retaining a large amount of air, having good warmth retention; at the same time, the hand feeling is soft and delicate, being very skin-friendly when worn close to the body; at the same time, the knitted fabric also has good ductility and breathability, and the wearing experience is very comfortable.

[0028] Surface layer 10, inner layer 20

[0029] Binding yarn layer 30 DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] In order to further explain the technical solution of the present invention, the following will be elaborated in detail with reference to the accompanying drawings.

[0031] Refer to Figures 1 to 6, A comfortable and shapely knitted sportswear, including a clothing body spliced by knitted fabrics. The knitted fabrics include a surface layer 10, a lining layer 20 integrally woven by a double-sided circular knitting machine, and a binding yarn layer 30 for connecting the surface layer 10 and the lining layer 20. The surface layer 10 is interwoven by face yarns, the lining layer 20 is interwoven by bottom yarns, and the binding yarn layer 30 is interwoven by binding yarns. The surface layer 10 includes alternately arranged first plain weave areas and first piqué areas. The first plain weave areas are interwoven by 40S / 1 cotton yarns in a plain weave knitting method, and the first piqué areas are interwoven by 100D / 36F polyester yarns in a piqué organization. The binding yarn is 100D / 36F polyester yarn. The lining layer 20 includes alternately arranged second plain weave areas and second piqué areas. The second plain weave areas are interwoven by 32S / 1 cotton yarns in a plain weave knitting method, and the second piqué areas are interwoven by 100D / 36F polyester yarns in a piqué organization.

[0032] In the selection of materials for the present invention, polyester and cotton yarns are selected. D in the present invention, which is called the denier number in the industry, refers to the weight (in grams) of 9000 meters of silk. F in the present invention refers to the number of fine fibers in a yarn.

[0033] Polyester is crisp, shapely, with a thermal conductivity coefficient of 0.084 W / (m·K), slightly higher than that of cotton and only one-third of that of nylon. It has no icy feeling of nylon when worn next to the skin in spring and autumn, and has a very high bulkiness and strong air retention ability, with warmth retention comparable to that of cotton. However, it has a rough hand feeling and poor skin-friendly property, and is most suitable for making the binding yarn layer 30 when used as a sandwich fabric or an air layer.

[0034] Cotton has a soft skin-friendly property, absorbs moisture and has no static electricity, and has a high-grade cotton texture. Its thermal conductivity coefficient is 0.071 - 0.073 W / (m·K), higher than that of viscose and lower than that of polyester. It is very comfortable to wear next to the skin in spring and autumn, has a very high bulkiness and strong air retention ability, and has good warmth retention. It is more suitable for making the surface layer 10 and the lining layer 20 of a sandwich fabric or an air layer. However, it is prone to wrinkling and the wrinkles are not easy to disappear, has poor shape retention, and is prone to arching and deformation during wearing and washing.

[0035] Therefore, the materials selected for the present invention are cotton and polyester, and the difficulty is to solve the problem of easy deformation of cotton.

[0036] The yarns of the surface layer 10 of the present invention are selected as JC40S / 1, and a small part is DTY SD 100D / 36F polyester yarn. The yarns of the lining layer 20 are selected as JC32S / 1, and a small part is DTY SD 100D / 36F polyester yarn. The binding yarn is selected as DTY SD 100D / 36F polyester yarn. JC represents combed pure cotton, and DTY is drawn textured yarn. The detailed description is as follows:

[0037] ① The face and the inner layer 20 are made of cotton fiber. The 328 cotton is the standard grade stipulated by the national standard (the first number represents the grade, and the last two numbers represent the fiber length). The grade is 3, the fiber length is 28mm, and it can spin 40 - 60S cotton yarn. The cotton selected for this invention is above grade 3, with a fiber length above 28mm, a fiber strength of 4 - 5 cN / dtex, a short fiber rate of 12%, uniform fiber length, an impurity content of 2.5%, and a Micronaire value of 3.7 - 4.2. The cotton quality is relatively good among domestic fine cotton, which can make the cotton yarn have higher strength, smoother surface, better color, more uniform evenness, fewer defects, and fewer impurities, and improve the problems of more hairiness and pilling on the fabric surface;

[0038] ② The spinning method selects compact siro spinning, which makes the fabric surface flat and smooth, with a soft hand feeling, good air permeability, and extremely high grade, further improving the problems of more hairiness and pilling on the fabric surface;

[0039] ③ The surface layer 10 selects JC40S / 1. The yarn is finer, making the surface layer 10 feel softer and more delicate, with a higher quality sense, and having better stiffness. The two are well balanced. If the yarn count is coarser, the fabric surface touch will become worse and the quality sense will decline. If the yarn count is finer, the stiffness of the surface layer 10 will decrease significantly;

[0040] The inner layer 20 selects 32S / 1. The relatively thick yarn makes the inner layer 20 maximize the stiffness on the basis of ensuring softness and skin - friendliness. The two are well balanced. If the yarn count is coarser, the skin - friendliness of the inner layer 20 will decrease significantly, and the wearing experience will be uncomfortable. If the yarn count is finer, the stiffness of the inner layer 20 will decrease significantly;

[0041] ④ The binding yarn selects DTY SD 100D / 36F polyester yarn. This denier is more appropriate. If the denier is smaller, that is, mostly using 75D, which is also the most commonly used binding yarn specification, the binding yarn layer 30 will become thinner, the ability to retain air will be greatly reduced, the warmth retention property will become worse, and the yarn will become thinner, unable to support the face and inner layer 20 well, and the stiffness will also decline. If the denier is larger, that is, rarely using 150D, it will be coarser than the face yarn, making the surface layer 10 unable to cover the binding yarn coils well;

[0042] The binding yarn is located in the middle layer. The polyester material itself is stiff and shaped. Coupled with the spinning method being DTY, which belongs to a drawn - textured yarn, it is coiled like a spring, with a high denier and a low F number. On the one hand, the yarn is stiff and hard, making the fabric stiff and shaped. On the other hand, the yarn is relatively thick, making the middle layer thicker, able to retain a large amount of air, making the fabric thick and warm. Among them, SD represents semi - dull;

[0043] In summary, JC40S / 1 of the surface layer 10 is equivalent to 133D, JC32S / 1 is equivalent to 166D, the binding yarn is 100D, and the yarns of the surface and inner layers 20 are all thicker than the binding yarn, which can well cover the binding yarn coils. The characteristics of cotton are reflected in both the surface and inner layers 20. Moreover, the cotton yarn of the surface layer 10 is finer and has better stiffness, the cotton yarn of the inner layer 20 is the thickest and has good stiffness, and the binding yarn is relatively the thinnest and has the best stiffness. The surface layer 10 is strongly supported by the binding yarn layer 30 and the inner layer 20, and the structure is more stable. Compared with most wire cloths and air layers, when the same yarn count is selected for the inner layer 20 and 75D polyester is used as the binding yarn, it has better stiffness and warmth retention.

[0044] (3)Weaving

[0045] The organizational structure of the present invention is an air layer structure, and the surface and inner layers 20 are fine pique, which is described in detail as follows:

[0046] Routes 1, 5, 7, 11, 13, 17, 19, 23, 25, 29, 31, 35, 37, 41, 43, 47 are reverse coils, that is, the inner layer coils 20;

[0047] Routes 2, 4, 8, 10, 14, 16, 20, 22, 26, 28, 32, 34, 38, 40, 44, 46 are front coils, that is, the surface layer coils 10;

[0048] Routes 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39, 42, 45, 48 are 1+1 rib structures.

[0049] ① Every 3 routes form 1 small cycle: First, the 3rd route weaves the 1st loop-forming system, using DTY SD 100D / 36F polyester yarn to weave a 1+1 rib row as the binding yarn; Secondly, the 2nd route weaves the 2nd loop-forming system, the upper needle bed does not weave, and the lower needle bed weaves. What the lower needle bed weaves is the surface layer 10, and the front coils it weaves itself and the front rib coils of the 3rd route 1+1 rib that have been formed are strung together; Secondly, the 1st route weaves the 3rd loop-forming system, the lower needle bed does not weave, and the upper needle bed weaves plain stitches. What the upper needle bed weaves is the inner layer 20, and the reverse coils it forms itself and the reverse rib coils of the 3rd route 1+1 rib that have been formed are strung together.

[0050] Through the cooperation of three routes, an air layer organizational structure composed of the surface layer 10, the middle layer (i.e., the binding yarn layer 30), and the inner layer 20 is formed. The binding yarn is straight and stiff, which can better support the surface and inner layers 20, making the fabric stiff and shaped. Moreover, it is relatively thick, making the middle layer thicker, and a large amount of air can be retained, making the fabric thicker and warmer than when 75D polyester is used as the binding yarn.

[0051] ② Every 12 paths in 4 small cycles form a medium cycle, and 48 paths in 4 medium cycles form a complete large cycle:

[0052] First, in the first 3 small cycles of a medium cycle, the surface layer 10 yarn uses JC40S / 1 and weaves a plain weft, which is equivalent to 133D, much thicker than the middle layer tying yarn 100D. It can well cover the front rib coils of the 1+1 rib formed by the middle layer tying yarn 100D, and the all-cotton characteristics of JC40S / 1 are reflected in the surface layer 10.

[0053] Second, in the first 3 small cycles of a medium cycle, the inner layer 20 yarn uses JC32S / 1 and weaves a plain weft, which is equivalent to 166D, much thicker than the middle layer tying yarn 100D. It can well cover the reverse rib coils of the 1+1 rib formed by the middle layer tying yarn 100D, and the all-cotton characteristics of JC32S / 1 are reflected in the inner layer 20.

[0054] Then, in the 4th small cycle of a medium cycle, the surface layer 10 yarn uses 100D. In the first medium cycle, it weaves a plain weft, which is forming loops (KKKKKKKK); in the second medium cycle, it weaves forming loops + tucking (KTKTKTKT), where K represents forming loops and T represents tucking; in the third medium cycle, it weaves a plain weft, which is forming loops (KKKKKKKK), and in the fourth medium cycle, it weaves tucking + forming loops (TKTKTKTK), thus forming a 4-mode single jersey, ensuring that on the basis of the horizontal and vertical connection of the surface layer 10 forming loops, a new diagonal connection of tucking is added, changing the connection of the surface layer 10 from a quadrilateral connection similar to the first-generation wire cloth and air layer to a triangular connection, making the connection of the surface layer 10 more stable, with dark diagonal lines appearing on the surface layer 10, significantly improving the technical problems of the first-generation wire cloth and air layer being prone to arching and deformation in terms of structure. Moreover, it has the same thickness as the middle layer tying yarn 100D and can well cover the front rib coils of the 1+1 rib formed by the middle layer tying yarn 100D. Even if there is a certain amount of leakage, it doesn't matter. The yarn used in this part is the same, reflecting the polyester characteristics of 100D. More importantly, there is a complete 4-mode single jersey cycle for every 16 paths of front coils, and the proportion of the jersey structure is only 25%. The remaining 12 paths are plain weft, accounting for 75%. The arrangement is 3 paths of plain weft + 1 path of 4-mode single jersey structure. The jersey structure is dispersed, and the 100D polyester yarn used for the jersey structure is much thinner than the JC40S / 1 yarn used for the plain weft, forming a small jersey effect with an existing but not obvious concavo-convex feeling, making the surface layer 10 feel delicate and soft, and improving the technical problems of the obvious concavo-convex feeling and too rough hand feeling of ordinary jersey.

[0055] Finally, in the fourth small loop of a medium loop, the inner layer 20 yarn uses 100D. In the first medium loop, plain weft knitting is performed, which is forming loops (KKKKKKKK). In the second medium loop, it is forming loops + tucking (KTKTKTKT). In the third medium loop, plain weft knitting is performed, which is forming loops (KKKKKKKK). In the fourth medium loop, it is tucking + forming loops (TKTKTKTK), thus forming a 4-mode single jersey, ensuring that on the basis of the horizontal and vertical connection of the inner layer 20 forming loops, a new diagonal connection of tucking is added, changing the connection of the inner layer 20 from a quadrilateral connection similar to the first-generation wire-inserted fabric and air layer to a triangular connection, making the connection of the inner layer 20 more stable. Dark diagonal lines appear on the inner layer 20, significantly improving the technical problems of the first-generation wire-inserted fabric and air layer being prone to arching and deformation in terms of structure. Moreover, it has the same thickness as the middle layer binding yarn 100D, and can better cover the reverse rib loops of the 1+1 rib formed by the middle layer binding yarn 100D. Even if there is a certain leakage, it doesn't matter. The yarn used in this part is the same, reflecting the polyester characteristics of 100D. More importantly, there is a complete 4-mode single jersey cycle for every 16 reverse loops, and the proportion of the jersey structure is only 25%. The remaining 12 loops are plain weft, accounting for 75%. The arrangement is 3 loops of plain weft + 1 loop of 4-mode single jersey structure. The jersey structure is dispersed, and the 100 polyester yarn used for the jersey structure is much finer than the JC32S yarn used for plain weft, forming a small jersey effect with almost no sense of unevenness, making the inner layer 20 feel delicate and soft, and improving the technical problems of the obvious unevenness and too rough hand feeling of ordinary jersey, and being very skin-friendly when worn next to the skin.

[0056] In short, 25% of the knitting loops of the surface layer 10 and the inner layer 20 are changed to the jersey structure, achieving a triangular connection between the surface layer and the inner layer 20, significantly improving the shape retention of the surface and inner layers 20 in terms of structure, realizing the complementary advantages of plain weft and jersey structures. Moreover, 25% of the materials of the surface layer 10 and the inner layer 20 are changed to polyester, and the yarn is thicker, being stiffer and more rigid than cotton yarn, further improving the shape retention of the surface and inner layers 20. The existence of 75% cotton materials in the surface layer 10 and the inner layer 20 makes the overall visual and tactile feelings still those of cotton materials, realizing the complementary advantages of polyester materials and cotton materials.

[0057] ③During weaving, the proportion of JC40S / 1 in the surface layer 10 (by mass) is 25%, the proportion of 100D polyester filament in the surface layer 10 is 8.4%, and the total proportion is 33.4%. The proportion of JC32S / 1 in the inner layer 20 is 30%, the proportion of 100D polyester yarn in the inner layer 20 is 10%, and the total proportion is 40%. The proportion of 100D polyester yarn in the middle layer is 26.6%. The weft plain weave coils formed by JC40S / 1 in the surface layer 10 and JC32S / 1 in the inner layer 20, the 4-mode single bead coils formed by 100D polyester yarn in the surface layer 10 and 100D polyester yarn in the inner layer 20, and the 1+1 rib coils formed by the 100D polyester yarn of the middle layer binding yarn are tightly set from the ratio of each yarn count to the setting of the coil length of each yarn count, making the surface layer 10 itself, the inner layer 20 itself, and the middle layer and the surface and inner layers 20 achieve extremely tight connection, further improving the shape retention of the fabric.

[0058] (4)Dyeing and finishing:

[0059] ①Anti-pilling treatment: Treat the surface of the cotton fabric with bio-enzyme to improve the smoothness of the fabric surface and the anti-pilling performance of the fabric.

[0060] ②Degreasing: To ensure the subsequent dyeing effect of the fabric and the hand feeling of the finished fabric, the greige fabric needs to go through two processes to remove the oil agent on the greige fabric. First, it is degreased by a degreasing machine, and then it is degreased by boiling in a vat.

[0061] ③Pre-setting: Before dyeing, pre-set the greige fabric to allow the fabric surface to fully retract.

[0062] ④Dyeing polyester: After the pre-setting is completed, enter the dyeing vat and first dye the polyester with disperse dyes.

[0063] ⑤Medium setting: Immediately after dyeing polyester, perform medium setting to eliminate the wrinkling problem caused by dyeing and retract the fabric surface again.

[0064] ⑥Dyeing cotton: Then use reactive dyes to dye cotton. The arrangement is 3-way cotton + 1-way polyester. There is a difference in the coloring of cotton and polyester. Cotton is darker and polyester is brighter. After dyeing, a faint dark bead ground effect is formed.

[0065] ⑦Final setting: After dyeing cotton, use low-temperature setting and add elastic auxiliaries.

[0066] Normally, it is one-time setting. In the present invention, it is changed to three times to obtain the finished fabric, so that the fabric is fully shrunk, smooth and bright without losing its richness, has good warmth retention, is extremely tight, stiff and shaped, has a soft and delicate hand feeling, forms a faint dark small bead ground style with dark twill, has a fashionable and novel style, the composition is 55% cotton and 45% polyester fiber, the gram weight is 310 g / m 2 , the width is 74 inches, and the yarn counts are JC40S / 1 25% + DTY100D / 36F 45% + JC32S / 1 30%.

[0067] The present invention has the following characteristics:

[0068] (1) Complementary advantages of plain weft and piqué structures are achieved: 25% of the knitting paths in both the front and inner layers 20 are changed to piqué structures. On the basis of the horizontal and vertical connections of the loops in the front and inner layers 20, new diagonal connections of tucks are added, changing the original quadrilateral connection to a triangular connection, making the connection between the front and inner layers 20 more stable, significantly improving the shape retention of the front and inner layers 20 structurally, and the arrangement is 3 - path plain weft + 1 - path 4 - mold single piqué structure. The piqué structures are dispersed. The yarn used for the piqué structure is 100D polyester yarn, which is 33D finer than the JC40S / 1 (133D) yarn used for the plain - weft front layer 10. A small piqué effect with an inconspicuous concave - convex feeling is formed on the front, and the front hand - feeling is close to the softness and fineness of plain weft. It is 66D finer than the JC32S / 1 (166D) yarn used for the plain - weft inner layer 20, forming a small piqué effect with almost no concave - convex feeling on the back, making the hand - feeling of the inner layer 20 reach the softness and fineness of plain weft, being very skin - friendly when worn next to the skin, and solving the technical problems of obvious concave - convex feeling and too rough hand - feeling of ordinary piqué, achieving the complementary advantages of plain weft and piqué.

[0069] (2) Complementary advantages of cotton and polyester are achieved: 25% of the materials in both the front layer 10 and the inner layer 20 are changed to polyester. The yarn is thicker and stiffer than cotton yarn, further improving the shape retention of the front and inner layers 20. The existence of 75% cotton materials in both the front layer 10 and the inner layer 20 makes the overall visual and tactile feelings still those of cotton materials, achieving the complementary advantages of polyester materials and cotton materials.

[0070] (3) In terms of appearance, the fabric surface is flat, smooth, with a faint small piqué effect, with hidden diagonal stripes, and the texture is novel and fashionable, meeting the personalized and fashionable needs of the post - 90s generation better than plain weft.

[0071] (4) Excellent shape retention: 25% of the knitting paths in both the front and inner layers 20 are changed to piqué structures, achieving triangular connections, and the material is changed to polyester. When weaving, the yarn - count ratio and coil length are closely set, and during dyeing and finishing, the fabric is shaped three times to make the fabric fully shrink back, improving the shape retention of the fabric structurally, materially, and in terms of density, making the fabric stiff and in good shape, without bulging or deforming during wearing and washing.

[0072] (5) Excellent comfort: There is a relatively thick binding - yarn layer 30, making the fabric very thick, capable of retaining a large amount of air, having good warmth retention; at the same time, the hand - feeling is soft and delicate, being very skin - friendly when worn next to the skin; at the same time, the knitted fabric has good ductility and breathability, and the wearing experience is very comfortable.

[0073] (6) Scientific and reasonable thickness: The fabric has a gram weight of 310 g / m 2 , and is compared with the commonly used knitted sweatshirt fabrics, silk - added fabrics, and air - layer fabrics in spring and autumn, with a gram weight of 250 - 300 g / m2 The grammage range fits.

[0074] (7) Extremely high cost performance: The average selling price is 300 - 400 yuan, which is very affordable.
