Description

TECHNICAL FIELD

[0001] The present application relates to a warp-knitted underpants, in particular to a warp-knitted full-formed super-elasticity non-size underpants, and belongs to the field of textile technology. BACKGROUND

[0002] With the improvement of people's living standards and the change of clothing concept, the wearing of underpants is becoming more and more common. On the market, the current underpants include thick underpants worn in autumn and winter and thin underpants worn in spring and summer, which have the common characteristics of tight fit and good concealing property. Most of the summer thin underpants are made by traditional weaving method and are composed of pieces, and the production process is relatively complicated. Moreover, the pieces have joint lines, and the size inclusivity is not strong, so the consumers need to compare the size to purchase, and it is difficult for women with large body to buy suitable underpants. At the same time, the tight fit characteristic makes the underpants usually cannot be worn alone, and must be matched with outer skirts or long outerwear to cover the hip curve, which increases the layers and thickness of the waist and hip wearing clothes. When wearing, the waist is tight, and the air permeability is also poor, and long-time wearing will cause discomfort due to sweat accumulation in the waist and abdomen and some positions prone to rubbing with the body. SUMMARY

[0003] In order to solve the problems in the prior art, the present application provides an underpants with good size adaptability and good moisture removal and air permeability.

[0004] According to the technical scheme provided by the application, a warp-knitted full-fashioned super-elastic non-size foundation garment is provided, which uses polyamide high-elastic yarn and polyamide covered yarn as raw materials, is knitted on a double-needle bed jacquard warp knitting machine, and has a machine gauge of E24-E32. During knitting, a ground comb and a jacquard comb are used. The polyamide high-elastic yarn is knitted into a base tissue, and the polyamide covered yarn is used for the jacquard comb. The ground comb is knitted into a chain stitch on the front and back needle beds respectively, and is connected by the transverse movement of the guide bars of the jacquard comb. When the jacquard comb is knitted into a warp pile padding motion, a thick ground cloth is formed, which is a medium-high elastic tissue. When the jacquard comb is alternately knitted into a warp pile padding motion and a warp flat padding motion, a garment piece cloth is formed, which is a high elastic tissue. When the jacquard comb is alternately knitted into a warp pile padding motion, a warp flat padding motion and a chain stitch motion, a garment piece cloth is formed, which is a super-elastic tissue. Finally, the warp-knitted full-fashioned foundation garment piece is formed, which is divided into three parts filled with different transverse elongation tissues: a first part covering the waistline to the abdominal circumference line, with a length of 12 cm and an on-machine density of 9; a second part covering the abdominal circumference line to the maximum thigh circumference line, with a length of 24 cm and an on-machine density of 8; and a third part covering the maximum thigh circumference line to the ankle circumference line, with a length of 62 cm and an on-machine density of 10. The first part is composed of a waist moisture guiding zone and a seam allowance zone connected to the upper part of the waist moisture guiding zone, and the seam allowance zone is located at the top end of the garment piece. The second part is composed of a breathable moisture discharge zone below the waist moisture guiding zone, a rear buttock elastic zone below the breathable moisture discharge zone, a support zone below the buttocks and on the sides, a front buttock elastic zone below the breathable moisture discharge zone, and a buttock moisture guiding zone below the front buttock elastic zone and the rear half buttock circumference support zone. The third part is composed of a leg elastic zone below the buttock moisture guiding zone, a cutting zone, and a hollowed-out zone on the outer sides of the two legs, and is knitted into two axisymmetric tube pieces. Among them,

[0005] The waist moisture guiding zone is knitted by a first high-elastic tissue, the seam allowance zone is knitted by a second high-elastic tissue, the breathable moisture discharge zone is knitted by a first super-elastic tissue, the rear buttock elastic zone is knitted by a third high-elastic tissue, the support zone below the buttocks and on the sides is knitted by a second high-elastic tissue, the front buttock elastic zone is knitted by a fourth high-elastic tissue, the buttock moisture guiding zone is knitted by a fifth high-elastic tissue, the leg elastic zone is knitted by a medium-high elastic tissue, the cutting zone is a single-layer cloth piece knitted by the jacquard comb on the front and back needle beds alternately, and the hollowed-out zone is knitted by a second super-elastic tissue with small round holes.

[0006] The beneficial effects of the present application are: (1) the adopted high-elasticity nylon filament and the nylon-ammonia covering yarn both have high strength, good moisture absorption and air permeability, and certain elasticity, which can meet the elasticity and strength requirements of the underpants, and increase the service life of the product; (2) the underpants are woven on a double-needle bed jacquard warp knitting machine, and are formed once, without the need for subsequent processing, thereby improving the production efficiency; (3) the line from the waist to the ankle of the human body is divided into three parts, and each part is further divided into different functional areas, the positioning forming technology is applied to fill the different elastic tissues meeting the requirements into the functional areas, so that the size of the underpants has strong inclusivity and has good moisture removal and air permeation, and the underpants are comfortable to wear.

[0011] The specific embodiments of the present application will be further described below in combination with specific drawings.

[0012] The leggings described in this invention are knitted on a double-needle bed Jacquard warp knitting machine, with a machine size between E24 and E32. This invention uses only two ground combs and two Jacquard combs. The yarn threading of each comb bar is shown in Table 1. The ground combs form chain weaves on the front and back needle beds, connected by the transverse movement of the Jacquard comb bars. The Jacquard warp knitting machine uses the ground combs to form the ground weave, and uses the Jacquard combs to create patterns covering these ground weaves. When the Jacquard combs are used for warp padding, a basic thin ground fabric is formed; when the Jacquard combs are used for chain weave, a mesh is formed on the fabric surface; when the Jacquard combs are used for warp pile padding, a thick ground fabric portion is formed. Based on the different elastic elongation rates of each weave after it leaves the machine, the weaves are divided into medium-high elastic weaves with a transverse elongation rate of 100%-150%, high elastic weaves with a transverse elongation rate of 150%-200%, and ultra-high elastic weaves with a transverse elongation rate of 200%-250%. This invention redesigns the garment structure of leggings, simplifying the irregular pattern of traditional form-fitting leggings into a vertical rectangle. The width of the garment piece (the leggings' circumference) is 50cm, and the length is 98cm. It utilizes a 20dtex-50dtex nylon high-elastic yarn weave for the base fabric, and 10dtex / 20dtex, 20dtex / 50dtex, 40dtex / 70dtex, or 70dtex / 70dtex nylon-spandex covered yarns for the Jacquard comb. Both yarns possess high strength, good moisture absorption and breathability, and a certain degree of elasticity, meeting the elasticity and strength requirements of leggings, increasing the product's lifespan. The tubular weave and the combined use of elastic yarns significantly improve the lateral tensile properties of the finished product, resulting in excellent wearing comfort.

[0014]

[0015]

[0016] like Figure 1 As shown, women have a smaller waist and abdomen circumference, making them less prone to lateral and longitudinal deformation during exercise. Therefore, the waistband of trousers should be designed with appropriate ease, allowing for a 10%-20% surface change rate during movement. Women also have wider pelvises, flatter and lower-set buttocks, with fat abundant between the lower edge of the gluteus maximus and the gluteal crease. This area experiences a >30% surface change rate during walking, standing, and lying down, making it difficult for trousers to fit snugly. For the tissue used to fill leggings, the higher the lateral elongation rate, the more suitable it is for placement in areas with larger circumferences and greater deformation rates.

[0017] Therefore, based on the different rates of change in body circumference and skin surface circumference during exercise, the area between the waistline and ankleline is divided into three parts: such as Figure 2As shown, the first part A is the waistline (WL) to the abdominal circumference line (MHL), with a length of 12 cm, an on-machine density of 9, and mainly using high-elasticity organization; the second part B is the abdominal circumference line (MHL) to the maximum thigh circumference line (FDL), with a length of 24 cm, an on-machine density of 8, and mainly using super-high-elasticity organization; and the third part C is the maximum thigh circumference line (FDL) to the ankle circumference line (AL), with a length of 62 cm, an on-machine density of 10, and mainly using medium-high-elasticity organization.

[0018] As shown in Table 2, the sweat rates of different parts of the human body are different during human movement, the sweat rate of the front torso is higher than that of the back torso during human activity, and the sweat amount gradually decreases from the middle to the side along the torso; the sweat amount of the middle lower back is the highest, and the sweat rate of the limbs is the lowest, and the sweat of the chest and back flows downward and accumulates at the waist, and the present application sets different functional areas on the three parts of the base pant pattern according to the sweat rate differences of different parts of the human body during human movement, and fills the organization mechanism with different elastic elongation in each functional area. Figure 3 As shown, the specific functional areas include a waist moisture-conducting area 1, a moisture-permeable and moisture-removing area 2, a rear hip elastic area 3, a support area 4, a front hip elastic area 5, an hip moisture-conducting area 6, a leg elastic area 7, a cutting area 8, a hollow area 9, and a seam area 10. Among them, the waist moisture-conducting area 1 and the hip moisture-conducting area 6 are formed by high-elasticity organization arranged longitudinally and alternately into false ribbing, respectively conducting sweat to the next area for heat dissipation, and the elasticities of the organization of the rear hip elastic area 3, the front hip elastic area 5, and the leg elastic area 7 are all different.

[0019] Table 2 shows the sweat rate distribution during human movement

[0020] Body part Sweating rate Chest (0.32 ± 0.07) mg / (cm 2 • min) Abdomen (0.35 ± 0.05) mg / (cm 2 • min) <!-- 3 -->]]> Upper back (0.59 ± 0.11) mg / (cm 2 ·min) Lower back (0.56 ± 0.08) mg / (cm 2 • min) Side torso (0.38 ± 0.09) mg / (cm 2 ·min) Shoulder (0.51 ± 0.13) mg / (cm 2 ·min)

[0021] As shown in Table 3, the present application draws the organization design of the required filling on the WKCAD software of Jiangnan University. The basic thin ground cloth formed when the jacquard comb makes warp flat filling is called green organization, which is represented by light gray cells; the mesh formed on the surface of the fabric when the jacquard comb makes chain knitting motion is represented by white cells; and the thick ground cloth part formed when the jacquard comb makes warp pile filling motion is called red organization, which is represented by dark gray cells. Draw a complete cycle for each organization, and save the cycle in the pattern library.

[0023]

[0024]

[0025]

[0026] The drawn functional partition image is imported into the WKCAD software, and then filled with the saved pattern cycle. The detailed design is described as follows:

[0027] (1) The first part A is composed of a waist moisture guide area 1 and a seam area 10, and the machine density is 9. Among them, the seam area 10 is located at the top end of the piece, knitted with high-elastic organization B1, and the seam area is folded and sewn in the middle, which is beautiful and comfortable when wearing. The upper side of the waist moisture guide area 1 is connected with the seam area 10, and is knitted with false rib high-elastic organization B8. The longitudinal strip of three red and one green has a tightening effect after integrated manufacturing, and the longer length in the longitudinal direction provides more friction force for compression, which can replace the waistband in the traditional underpants in cooperation with the double-layer structure of the seam area. Three columns of thick organizations tighten, protect the thin organizations, and the thickness difference between the thin and thick organizations forms a channel on the side close to the skin. After the sweat from the chest to the waist flows down and contacts the panty line, it will be quickly absorbed and flows downward under the action of gravity.

[0028] (2) The second part B is composed of a breathable and moisture-wicking area 2, a rear buttock elastic area 3, a support area 4, a front buttock elastic area 5, and an buttock moisture guide area 6, and the machine density is 8. The breathable and moisture-wicking area 2 is located below the waist moisture guide area 1, connecting the waist moisture guide area 1 with the front and rear buttock elastic areas, and is filled with super-elastic organization C1, which is not uniform in height, shorter in the abdomen and back, and longer on both sides of the body, forming a soft arc line. The red and green organizations are matched with small mesh, and the thickness is uniform, and the hollow area is also uniformly distributed, which can quickly discharge the sweat and heat from the waist while ensuring that there is no large area exposed on the waist; the rear buttock elastic area 3 is the main body of the rear buttock of the underpants, distributed below the breathable and moisture-wicking area, filled with high-elastic organization B3, which has excellent transverse stretch performance, as well as good shielding performance and air permeability; the front buttock elastic area 5 is the main body of the front buttock of the underpants, distributed below the breathable and moisture-wicking area, filled with high-elastic organization B5, which has smaller transverse stretch performance than B3 of the rear buttock elastic area 3, and the length of the front piece is smaller than that of the back piece under the same stretch force at the same girth, making the underpants more body-fitting when worn; the support area 4 is distributed in the form of a strip under the buttocks and on the sides of the buttocks, in order to make the support more effective, it is filled with high-elastic organization B1 with lower elastic elongation, starting from the buttock and extending to the front of the body from both sides, and the transverse elongation of the support area 4 is smaller than that of the buttock elastic area 3, which can provide higher pressure to the human body under the same stress environment and support the buttock fat during exercise. The thick organization also provides good wear resistance, increasing the service life of the product; the buttock moisture guide area 6 is distributed below the front buttock elastic area 5 in the front half of the hip circumference and below the support area 4 in the rear half of the hip circumference, and is connected with the leg elastic area 7 below, and is filled with red and green false rib B7. This structure, like the waist moisture guide area 1, can form a longitudinal sweat guide channel to guide the sweat to the leg moisture guide area for heat dissipation.

[0029] (3) The third part C is composed of a leg elastic zone 7, a cutting zone 8 and a hollow zone 9, and the upper machine density is 10. The third part is the part from the maximum thigh circumference downwards, and thus the foundation pants need to be divided into two axisymmetric tube pieces for knitting. The leg elastic zone 7 is filled with the red organization A1, which is tight but not tight, and can provide good support for the leg muscles; the cutting zone 8 is distributed between the double leg patterns, at this time the jacquard card forms loops on the front and back needle beds alternately, and the front and back two pieces of base cloth are connected and knitted into a single layer of cloth, which can be divided into two when cut along the center, forming the part of the leg of the foundation pants; the hollow zone 9 is distributed on the outside of the double legs, starting from the maximum thigh circumference line downwards, ending at the knee, and the overall shape is a vertical rectangle, but the four corners are changed into round corners. The super-high elastic organization C5 with high transverse elongation is filled, which can avoid the large difference between the second part and the third part of the foundation pants due to the difference in knitting density and elastic elongation, and the leg side holes are still small round holes. Such design is not only breathable and moisture permeable, but also quite beautiful in appearance.

[0030] The high-elasticity size-free foundation pants are knitted by the full-forming weaving method, and after being taken off the machine, they do not need extra gusset processing, only a small amount of cutting and edge wrapping treatment of the waist and legs can be made into the product, greatly shortening the process flow of producing foundation pants and improving the production efficiency.
