DETAILED DESCRIPTION OF THE EMBODIMENTS

(16) In the following, the preferred embodiments of the present disclosure will be described in detail with the accompanying drawings, such that the advantages and features of the present disclosure can be more easily understood by those skilled in the art, and the scope of protection of the present disclosure can be more clearly defined.

Embodiment

(17) In order to facilitate the following description, various parts of the human body are distinguished. The human body is mainly divided into trunk, upper limbs, and lower limbs. The trunk includes shoulders, chest, waist and abdomen, and back. The upper limbs include upper arms, elbows and lower arms. The lower limbs include hips, thighs, knees, and shanks. The junction of the trunk and the upper limb is located at armpit.

(18) As different parts of the human body have different sweat volumes and require different support pressures in skiing, the human body parts are divided into function divisions. Specifically, there are two ways for functional dividing. The first way is to divide various parts of the human body into a high sweating area, a medium sweating area, and a low sweating area according to the distribution of sweat glands on the surface of human skin. As shown in FIG. 1, underarms, the chest, the back, the inner thighs and the inner shanks are high sweating areas, the rest parts of the trunk and thighs are medium sweating areas, and the upper limbs and the shanks are low sweating areas. Based on this, in order to improve the wearing comfort of the compression suit, thermal-wet comfort design should be carried out in the high sweating area and the medium sweating area during wearing.

(19) The second is to divide all parts of the human body into a high pressure area, a medium pressure area and a low pressure area according to the comfortable pressure threshold of the surface of the human skin and the contractility of muscles in different parts of the body during exercise. As shown in FIG. 2, the shoulders, the chest and the knees are high pressure areas, the upper arms and the rest of the trunk are medium pressure areas, and the lower arms and lower limbs are low pressure areas. Based on this, in order to improve the wearing comfort of the compression suit, the pressure comfort design should be carried out in the high pressure area and the medium pressure area in the designing.

(20) In addition, in skiing, the joints of the knees and the elbows are bent to a great extent, the friction of the inner thigh is serious, and the muscles at the outer thigh and the rear shank bulge greatly. Therefore, the compression suit needs to be designed for safety protection of the knees, the elbows, the inner thighs, the outer thighs, and the rear shanks.

(21) Based on the above function division of the human body parts, as shown in FIG. 3-FIG. 13, a fully-formed compression ski suit knitted by four needle beds of the present disclosure includes a top, and trousers. Each of a top and trousers is integrally knitted.

(22) As shown in FIG. 3, in the top, according to the functional division of the human body parts, corresponding functional knitted structures are arranged on shoulder parts, upper arm parts, elbow parts, a chest part and a back part of the top, and the rest parts adopt the basic knitted structures in the prior art, specifically as follows: (1) The shoulder part is located at the high pressure area, and thus the purpose of reducing pressure should be achieved in the design. Specifically, as shown in FIG. 4, the shoulder part is provided with a first knitted structure. The first knitted structure is knitted by surface yarns and inner yarns with different shrinkage ratios to form a partially convex three-dimensional structure 40 that is partially detached from human skin. Through the partially convex structural features, the pressure on the shoulder can be reduced when the ski suit is worn, and the pressure comfort of wearing for a long time can be ensured. (2) The upper arm part is located at the medium pressure area, and the armpit is located at a high sweating area. Therefore, the design should focus on the moisture drainage of sweat at the armpit. Specifically, as shown in FIG. 5, the upper arm part is provided with a second knitted structure, the second knitted structure is a pore structure having an inverted V-shape pattern 50. The pore effect is achieved through a tuck stitching process, or a loop transfer processes. Through bionic design of inverted V-shapes, a water channel is formed in the inner layer of the second knitted structure (that is, the side close to human skin) to guide the sweat at the armpit from the inner layer of the second knitted structure. (3) The elbow part is provided with a third knitted structure. As shown in FIG. 6, the third knitted structure is a partially pleated structure 60 to provide sufficient motion margin to adapt to the large stretching amount at the joint, thus ensuring the degree of freedom of multi-angle bending at the joint. (4) The chest part is located at the high sweating area and the high pressure region, and thus both thermal-wet comfort and pressure comfort should be taken into account in the design. Specifically, as shown in FIG. 7, the chest part is provided with a fourth knitted structure, a fifth knitted structure and a sixth knitted structure from the chest to a body side. The fourth knitted structure, the fifth knitted structure and the sixth knitted structure are pore structures formed by using a stitch transfer process or a loop transfer process, and pore sizes of the fourth knitted structure, the fifth knitted structure and the sixth knitted structure are reduced in turn. The surface yarns of the fourth knitted structure, the fifth knitted structure and the sixth knitted structure are wool yarns to improve the warmth retention property of the ski suit, and the inner yarns are moisture-wicking fiber yarns.

(23) In order to improve pressure comfort, a certain proportion of elastic yarns is added in the inner yarns of the fourth knitted structure, the fifth knitted structure and the sixth knitted structure, and the addition amount of the elastic yarns in the fourth knitted structure, the fifth knitted structure and the sixth knitted structure decreases in turn, thus forming a pressure gradient that the pressure gradually decreases from the chest to the body side. (5) The back part is located the high sweating area and the medium pressure area, and thus both thermal-wet comfort and pressure comfort should be taken into account in the design. Specifically, as shown in FIG. 7, the back part is provided with a seventh knitted structure, and the seventh knitted structure is a pore structure. A certain proportion of elastic yarns is added in the inner yarns of the seventh knitted structure, thus making the back part form a pressure gradient that the pressure gradually decreases from the middle to the body side.

(24) It should be noted that the seventh knitted structure, the fourth eave structure, the fifth knitted structure and the sixth knitted structure are all pore structures imitating leaf pores. After human motion, the muscles bulge, and the pore sizes in the fabric also change accordingly, thus achieving the purpose of dynamically adjusting human heat balance and achieving body thermal management.

(25) As shown in FIG. 3, in the trousers, according to the functional division of the human body parts, corresponding functional knitted structures are arranged on outer thigh parts, inner thigh parts, knee parts, and rear shank parts of the trousers, and the rest parts adopt the basic knitted structures in the prior art, specifically as follows: (1) The muscles on the outer thigh will bulge after exercise, and thus the outer thigh part is provided with an eighth knitted structure. As shown in FIG. 8, the eighth knitted structure is a strip structure 80, which can provide sufficient space structure for muscle stretching and ensures the wearing comfort during exercise. (2) The inner thigh is located at the high sweating area, and has serious friction during exercise. Therefore, both thermal-wet comfort and pressure comfort should be taken into account in design. Specifically, the inner thigh part is provided with a ninth knitted structure. As shown in FIG. 9, the ninth knitted structure includes is a pore structure 90 having a greater thickness than that in areas adjoining the ninth knitted structure. The inner yarn is a moisture-wicking yarn, and the surface yarn is a yarn with a low friction coefficient. (3) The knee is located at the high pressure area, and the knee joint moves and bends more. Therefore, pressure comfort and safety protection should be taken into account in the design. Specifically, the knee part is provided with a tenth knitted structure, an eleventh knitted structure, and a twelfth knitted structure. As shown in FIG. 6, FIG. 10 and FIG. 11, the tenth knitted structure is located at the front side of the knee part, and is a double-layer knitted structure. Elastic yarns and wear-resistant yarns are added in the inner yarns to adjust the pressure and service life of the fabric. The eleventh knitted structure is located on both sides of the knee part, and is a three-dimensional convex structure 110, which is in incomplete contact with the skin to guarantee the wearing comfort. The content of the elastic yarns in the eleventh knitted structure is greater than that in the tenth knitted structure, thus enhancing supporting pressure on both sides of the knee. The twelfth knitted structure is located on the rear side of the knee part, which has the same structure as the third knitted structure, and is a partially pleated structure. (4) The muscles at the rear shank will bulge during exercise, the rear shank part is provided with a thirteenth knitted structure, as shown in FIG. 12, which is a compact jacquard knitted structure to enhance the supporting pressure on the rear shank.

(26) In some embodiments, at least one of cotton, linen, silk, hair (wool, rabbit hair, etc.), viscose, polyester, polyamide, polyvinyl alcohol, polyurethane, etc. can be selected for the surface yarn and the inner yarn according to actual needs. The elastic yarns may be at least one of polyurethane fiber (PU), polyolefin elastic fiber (XLA), T400 composite fiber, polybutylene terephthalate fiber (PBT), polytrimethylene tereph-thalate fiber (PTT), polyamide-wrapped polyurethane fiber, and polyester-wrapped polyurethane fiber. The wear-resistant yarn may be at least one of ultrahigh-molecular-weight polyethylene fiber, and polyamide fiber.

(27) The present disclosure further provides a knitting method of a compression ski suit. A flat knitting machine with four needle beds is used to knit the top and the trousers, respectively, where the knitting speed does not exceed 0.8 mis. When knitting the top, two yarn feeders are used for each of the body, the sleeve, and the right sleeve. Surface yarns are fed into one yarn feeder, inner yarns are fed into the other yarn feeder, and then knitting is carried out from bottom to top. When knitting the trousers, two yarn feeders are used for each of the left trouser leg and the right trouser leg. Main-Surface yarns are fed into one yarn feeder, inner yarns are fed into the other yarn feeder, and then knitting is carried out from bottom to top.

(28) A curve shape in fit with the human body is formed at the junction of the body and each of the left sleeve and the right sleeve, and the junction of the left trouser leg and the right trouser leg through cast on and bind off, and then a seamless connection is formed through loop transfers during knitting.

(29) During knitting, when involving in partial knitting or wrapping-turning action, the edge part is knitted by stitch transferring and thread pressing instead of using a hanging eye process, which can reduce the requirements for the size of the pattern.

(30) Furthermore, after the knitting of the top and the trousers, the top and the trousers need to be subjected to after-treatment processes such as washing, and ironing and pressing.

(31) In the present disclosure, the knitting of the compression ski suit is achieved by the four needle be the flat knitting machine with four needle beds, and the functional knitted structure for pressure comfort, thermal-wet comfort and safety protection is introduced into the compression ski suit according to the sweat volumes, skin pressure thresholds and motion characteristics of different parts of human body, such that the compression ski suit may have pressure comfort, thermal-wet comfort and safety protection, and the knitted structure of the compression ski suit is enriched, and the problem that a single knitted structure cannot adapt to different functional requirements of different parts of the compression ski suit in skiing can be avoided. The knitting can avoid the indentation and uncomfortable wearing caused by the connection of knitting pieces, and improve the fit of the clothing to a certain extent.

(32) The above embodiments are only for describing the technical concept and characteristics of the present disclosure, with the purpose of making those skilled in the art understand and implement the content of the present disclosure, rather than limiting the scope of protection of the present disclosure. All equivalent changes or modifications made according to the spirit of the present disclosure should be included in the scope of protection of the present disclosure.
