Description

Technical Field

[0001] The invention relates to windproof, cold-resistant and warm-keeping trousers and a cutting and manufacturing method thereof, belonging to the technical field of clothing. Background Art

[0002] Warm pants are necessary winter clothing, especially for people with knee arthritis. If you fail to keep your legs warm in time when autumn and winter come, you will have knee pain. The pain will disappear after proper protection. There are many medical reports. Although it cannot directly prove that the cold wind and cold in winter are the main factors that directly cause arthritis, the cold in winter can indeed aggravate the pain of knee joints.

[0003] At present, most of the winter cold-proof products on the market are made of highly elastic knitted outer fabrics and knitted elastic fleece lining fabrics. It has good shape-adaptability, but it is tightly bound on the legs, making people who are afraid of cold even colder, and the cold wind and cold air are directly against the skin; when the elasticity of the inner and outer layers of these cold-proof products is increased, the gap between the fibers will also increase, which will affect the cold-proof and warm-keeping to a certain extent. There is another type of winter warm-keeping product that uses an outer fabric that is not breathable. When wearing it, the sweat gas naturally breathed by the body cannot be discharged, making the clothes feel damp. Traditional cotton trousers are warm and breathable but have no elasticity. They are not beautiful when worn, and have poor comfort and shape-adaptability. Therefore, it is necessary to develop a kind of warm-keeping trousers that can be both warm and breathable, and have a certain elasticity to improve comfort. Therefore, finding the best insulation material and method in winter to make warm-keeping trousers that are both warm and not bloated and can keep beautiful and slim is the research goal of industry insiders. Summary of the invention

[0004] The purpose of the present invention is to select different materials on the same trouser body so that each part has a corresponding function, that is, to select several fabrics to splice to make a pair of warm trousers to meet the needs of different parts, so that it has a better effect in resisting the cold in winter.

[0005] To achieve the above object, the present invention adopts the following technical solutions:

[0006] A pair of windproof, cold-resistant and warm trousers, consisting of an outer windproof layer and an inner warm fleece layer, with a reinforced windproof interlayer arranged at the knees, and the outer windproof layer and the inner warm fleece layer having the same design at the corresponding parts;

[0007] The trouser leg portion includes a front trouser piece and a back trouser piece; the front trouser piece is divided into a front trouser piece upper side splicing piece and a front trouser piece main body by a straight line between the intersection of the waistline and the center line of the front trouser piece to a point on the center line of the front trouser piece that is higher than the hip circumference line, and an arc line between the point on the center line of the front trouser piece that is higher than the hip circumference line to the intersection of the front trouser piece outer seam line and the horizontal crotch line;

[0008] The back trouser piece is divided into a back trouser piece upper side splicing piece and a back trouser piece main body by a straight line between the intersection of the waistline and the back trouser piece centerline to a point on the back trouser piece centerline that is higher than the hip circumference line, and an arc line between the point on the back trouser piece centerline that is higher than the hip circumference line to a point on the back trouser piece outer seam that is lower than the crotch line;

[0009] A reinforced windproof interlayer is also arranged at the knee of the front trouser piece, which is located between the outer windproof layer and the inner warm fleece layer. The two edges of the windproof interlayer are sewn on the outer seam line and the inner seam line respectively. The outer side edge is longer than the inner side edge. The other two edges connecting the outer side edge and the inner side edge are straight lines or arcs, and the shape is similar to a trapezoid. The angle between the center line of the front trouser piece and the radial or weft direction of the interlayer fabric is 45°.

[0010] At the trouser legs of the thermal trousers, the length of the inner thermal fleece layer is greater than the length of the outer windproof layer. Preferably, the inner thermal fleece layer is 8-10 cm longer than the outer windproof layer. A reinforcement line is set every 1.5-2.5 cm, preferably 2 cm, of the inner thermal fleece layer that has grown. The reinforcement lines are symmetrically set on the inner and outer seams of the front and rear trouser pieces, and 4-5 pairs are set. People of different heights and leg lengths can cut the trouser legs according to their needs with reference to the reinforcement lines, and cut off the excess trouser legs. The bottom end of the outer windproof layer is sewn on the inner thermal fleece layer. In this way, the trouser length can be adjusted. The lining material of the inner thermal fleece layer has the characteristics of not unraveling or curling after low elasticity and high density compounding. After the excess trouser length is cut off at the required trouser length, the shape of the lining trouser legs will not change.

[0011] The front and rear trouser body parts and the inner and outer layers of the upper side splicing pieces of the front and rear trouser pieces, as well as the reinforced windproof interlayer are made of different fabrics. The thermal trousers are made by splicing several fabrics to meet the needs of different parts of the body, and can achieve better cold-proof effect while being comfortable to wear.

[0012] The elasticity of the inner thermal fleece layer material of the main body of the front and rear trouser pieces is less than that of the inner thermal fleece layer material of the upper side splicing pieces of the front and rear trouser pieces, and the thickness of the inner thermal fleece layer material of the main body of the front and rear trouser pieces and the inner thermal fleece layer material of the upper side splicing pieces of the front and rear trouser pieces is basically the same. The inner thermal fleece layer of the main body of the front and rear trouser pieces is made of low-elastic composite fleece, such as low-elastic high-density knitted polar fleece; the inner thermal fleece layer of the upper side splicing pieces of the front and rear trouser pieces is made of knitted fabric with rich elasticity, such as silver fox fleece. The elasticity of silver fox fleece is greater than that of polar composite fleece, and silver fox fleece and composite polar fleece are made of materials of equal thickness.

[0013] The elasticity of the outer windproof layer material of the front and back trouser body is less than that of the outer windproof layer material of the upper side splicing piece of the front and back trouser body. The outer windproof layer of the front and back trouser body is made of woven polyester plus spandex fabric or nylon plus spandex fabric, such as polyester 200D four-way stretch fabric, and the outer windproof layer of the upper side splicing piece of the front and back trouser body is made of elastic knitted fabric, such as swimwear fabric.

[0014] The knee reinforced windproof interlayer is made of high-density nylon fabric, which has no elasticity in the radial or weft direction (horizontal and vertical). The nylon fabric is cut on the bias, with the radial or weft angle of 45° with the center line of the front trouser piece, and the bias cutting makes it have a certain elasticity.

[0015] A method for cutting and making windproof, cold-resistant and warm trousers, comprising the following steps: cutting the upper side splicing pieces of front and rear trouser pieces and the outer windproof layer and the inner warm fleece layer of the main body of the front and rear trouser pieces according to the design of the above-mentioned warm trousers, wherein the warp and weft directions of the outer windproof layer and the inner warm fleece layer of the upper side splicing pieces of the front and rear trouser pieces are consistent with the horizontal and vertical directions of the splicing pieces (that is, the warp or weft direction of the fabric is consistent with the direction of the center line of the trouser piece), and the warp and weft directions of the knee windproof interlayer fabric are 45 degrees to the center line of the trouser piece; when sewing the upper side splicing piece of the inner warm fleece layer and the main body of the trouser piece, first use a narrow seam of a flat sewing machine to make an initial connection, and then use four-needle six-thread pressure sewing; when connecting the main body of the outer windproof layer trouser piece with the upper side splicing piece, sew the trouser piece The main body is placed on the splicing piece and sewn once with a flat sewing machine, and then sewn a second time with four-thread overlocking to reinforce the flat seam traces; the knee windproof interlayer is sewn to the outside of the inner thermal fleece layer or the inside of the outer windproof layer, the long side of the knee windproof piece is sewn at the same time as the outside of the front and back pieces of the trouser piece, and the short side of the knee windproof piece is sewn at the same time as the inside of the front and back pieces of the trouser piece, and the oblique straight line or oblique arc connecting the long side and the short side of the knee windproof piece is connected to the main body of the front trouser piece by a "Z" zigzag seam; the front and back trouser pieces of the inner thermal fleece layer at the lower end of the trousers are first narrowly sewed by a flat sewing machine, and then the edge of the narrow slit is completely wrapped in the four-needle six-thread stitch; the outer windproof layer and the inner thermal fleece layer at the trouser legs are reinforced by point-shaped overlapping sewing with a bartacking machine.

[0016] At 0.2cm above the lower edge of the inner and outer seams of the inner thermal fleece layer, use three-point reinforcement lines to reinforce the inner and outer seams. The reinforcement lines are perpendicular to the inner and outer seams. From 0.2cm above the trouser hem, sew a reinforcement line every 2cm or so. Sew symmetrically, and sew 4-5 pairs. The color of the reinforcement line is different from the color of the vertical line of the trouser seam.

[0017] The above-mentioned cutting method of the windproof interlayer at the knee includes the following steps: the cutting method of the windproof interlayer (nylon cloth) is bias cutting. First, a knee pattern is made, that is, the part of the front trouser piece at the knee is cut as the knee pattern, so that the length of the side corresponding to the outer seam is greater than the length of the side corresponding to the inner seam, and the two sides are connected by a slant line or an arc, and the center line of the front trouser piece is drawn; then, a square piece of cloth is taken, and the two adjacent sides of the square correspond to the radial or weft direction of the cloth, and a diagonal line is drawn, and the knee pattern is placed on the cloth, so that the center line of the front trouser piece on the pattern is aligned with the diagonal line of the square cloth, and the fabric required for the knee is cut according to the pattern. The windproof interlayer cloth has no elasticity in the radial or weft direction (horizontal and vertical), and bias cutting will make it have a certain elasticity.

[0018] Advantages of the present invention:

[0019] The upper side splicing of the outer windproof layer and the inner thermal fleece layer has the same elasticity inside and outside, and is rich in elasticity. When the waist, abdominal circumference, and hip circumference increase when the human body is sitting, there will be no feeling of being squeezed. All the elastic interfaces at the waist also increase the circumference to reduce friction when putting on and taking off, preventing obstruction. The outer windproof layer and the inner thermal fleece layer have low elasticity inside and outside the main trouser body, which has a double barrier effect in windproofing, and also has a certain effect on the loss of body temperature. The elasticity of low-elastic knitted fleece fabric and low-elastic woven fabric can meet the needs of daily activities. At the same time, the low-elastic fabric of the inner and outer main trouser body will not increase the horizontal and vertical fiber gaps when stretched, which is also a pair of thermal pants that can be windproof, cold-resistant, and warm at the same time.

[0020] The knee windproof interlayer forms a secondary reinforcement between the two main trouser surfaces, protecting the knee from external cold wind. The side length of the knee windproof piece sewn on the outer trouser edge is longer than the side length of the knee windproof piece sewn on the inner trouser edge in order to increase the windproof area of ​​the knee. The outer sides of the left and right legs are sensitive to cold wind, so the secondary windproof capacity needs to be increased. The inner side of the knee is not sensitive to cold wind stimulation because the left and right legs block each other. The side length of the inner side of the knee windproof piece is reduced to make the upper and lower lines connecting the two sides of the knee windproof piece have a certain degree of material. Because the knee is often bent, connecting the upper and lower knee windproof pieces with oblique straight lines or oblique arcs can increase stretching, making the knees comfortable and not tight when moving. The fabric is breathable and the windproof layer is thin, and the warm fleece is thick.

[0021] The trouser length can be adjusted, the inner warm fleece layer is longer than the outer windproof layer, and the different inner lengths make the inner trousers also have the function of outer trousers. The length of the trousers can be cut according to the length of the legs. A short fat person and a thin tall person can use the same size with the same hip circumference and waist circumference, so there will be no embarrassment that the trousers are not long enough for a tall person and the trousers are too long for a short person. The self-adjusting trouser length has changed the previous situation that the inner and outer trouser surfaces are integrated and the excess trouser length cannot be reduced, and the difficult sewing can be cut. Because a special machine is required, the ordinary daily sewing of the trouser hem cannot solve this technical problem, while the design of the present invention only requires the wearer to cut the excess trouser length under the reinforcement line.

[0032] The windproof, cold-resistant and warm-keeping trousers of the present invention are composed of an outer windproof layer and an inner warm-keeping fleece layer. A reinforced windproof interlayer is arranged at the knees, and the corresponding parts of the outer windproof layer and the inner warm-keeping fleece layer adopt the same design.

[0033] The trouser leg portion includes a front trouser piece and a back trouser piece; Figure 1 As shown, the front trouser piece includes a front trouser piece body 1 and a front trouser piece upper side splicing piece 2. The upper end of the front trouser piece upper side splicing piece 2 is a part of the waistline 7 outside the front trouser piece centerline 3, the outside is the outer waist (part of the outer seam line 5), the inside is a straight line from the intersection of the waistline 7 and the front trouser piece centerline 3 to a point on the front trouser piece centerline 3 that is higher than the hip circumference line 8, and an arc line 4 from the point on the front trouser piece centerline 3 that is higher than the hip circumference line 8 to the intersection of the front trouser piece outer seam line 5 and the crotch line 9. The portion of the front trouser piece other than the front trouser piece upper side splicing piece 2 is the front trouser piece body 1.

[0034] The back trouser piece includes a back trouser piece body and a back trouser piece upper side splicing piece. The upper end of the back trouser piece upper side splicing piece is a part of the back waistline outside the back trouser piece centerline, the outside is the outside waist (part of the outer seam line), the inside is a straight line between the intersection of the back waistline and the back trouser piece centerline to a point on the back trouser piece centerline that is higher than the hip circumference line 8, and an arc line between the point on the back trouser piece centerline that is higher than the hip circumference line 8 to a point on the back trouser piece outer seam line that is lower than the crotch line 9. The part of the back trouser piece other than the back trouser piece upper side splicing piece is the back trouser piece body.

[0035] A reinforced windproof interlayer 10 is also provided at the knee of the front trouser piece, which is located between the outer windproof layer and the inner warm fleece layer. The two sides of the windproof interlayer 10 are sewn on the outer seam line 5 and the inner seam line 6 respectively. The outer side is longer than the inner side. The other two sides are straight lines or arcs, and the shape is similar to a trapezoid. The angle between the center line 3 of the front trouser piece and the radial or latitudinal direction of the interlayer fabric is 45°.

[0036] At the trouser legs 11 of the thermal pants, the length of the inner thermal fleece layer is greater than the length of the outer windproof layer. Usually, the inner thermal fleece layer is 8-10 cm longer than the outer windproof layer. A reinforcement line 12 is set every 2 cm on the inner thermal fleece layer that grows out. The reinforcement lines 12 are symmetrically set on the inner and outer seams of the front and rear trouser pieces, and 4-5 pairs are set. People of different heights and leg lengths can cut the trouser legs according to their needs with reference to the reinforcement lines 12, and cut off the excess trouser legs. The bottom end of the outer windproof layer is sewn on the inner thermal fleece layer. In this way, the trouser length can be adjusted. The lining material of the inner thermal fleece layer has the characteristics of not loosening or curling after low elasticity and high density compounding. After cutting off the excess trouser length at the required trouser length, the shape of the lining trouser legs will not change.

[0037] The inner warm fleece layer of the main body of the front and back trousers is made of low-elasticity high-density knitted polar fleece; the inner warm fleece layer of the upper side splicing of the front and back trousers is made of elastic knitted fabric silver fox fleece. The elasticity of silver fox fleece is greater than that of polar fleece composite fleece, and the silver fox fleece and composite polar fleece are made of materials of equal thickness.

[0038] The outer windproof layer of the main body of the front and back trouser pieces is made of woven polyester plus spandex fabric or nylon plus spandex fabric, such as polyester 200D four-way stretch fabric, and the outer windproof layer of the upper side splicing pieces of the front and back trouser pieces is made of elastic knitted fabric, such as swimwear fabric, so that when the human body is moving, the fiber gap will not increase and affect the windproof, cold-proof and warm-keeping effects. The inner warm fleece layer and the outer windproof layer of the upper side splicing pieces of the front and back trouser pieces are both made of elastic fabrics to ensure consistent stretch.

[0039] The knee reinforced windproof interlayer 10 is made of high-density nylon cloth, which has no elasticity in the radial or weft direction (horizontal and vertical). The nylon cloth is cut in a biased manner, and the angle between the radial or weft direction of the nylon cloth and the center line of the front trouser piece is 45°. The biased cutting makes it have a certain elasticity, that is, when the square fabric of the same width and length is stretched at a diagonal angle of 45°, it has a certain elasticity. When it is stretched at the same time as the inner and outer trouser bodies, it maintains the same tension, and the thin nylon cloth will not leave marks on the outer trouser surface.

[0040] Crop:

[0041] like Figure 2As shown, the cutting method of the windproof interlayer 10 (nylon cloth) is bias cutting. First, make a knee pattern, that is, cut the part of the knee of the front piece of the trouser leg as the knee pattern, so that the length of the side corresponding to the outer trouser seam is greater than the length of the side corresponding to the inner trouser seam, and the two sides are connected by a diagonal line or an arc, and the center line of the front piece of the trousers is drawn; then, take a square high-density nylon cloth with equal length and width, draw a straight line from the diagonal line, and this line coincides with the center line of the trousers. When cutting the outer fabric, take the knee pattern and put it on the diagonal high-density nylon, so that the center line of the outer trouser surface is aligned diagonally with the high-density nylon square cloth piece, and cut the fabric required for the knee. Use the pattern to cut the required cloth piece of the knee required by the trouser body under the bias cutting of the nylon fabric. The upper and lower oblique arcs can once again increase the stretching performance, so that the legs will not feel tight when wearing. The outer side is longer than the inner side in order to increase the windproof protection of the knee, and the upper and lower ends are connected with the outer fabric or inner fabric of the trousers with a "Z"-shaped zigzag seam. Compared with straight lines, curves have a certain degree of stretchability, which can reinforce the knee pad without affecting the elasticity of the bias-cut knee pad layer.

[0042] According to the design and cutting of the above-mentioned thermal pants of the present invention, the upper side splicing pieces of the front and rear trouser pieces and the outer windproof layer and the inner thermal fleece layer of the front and rear trouser piece main body are obtained. Among them, the outer windproof layer and the inner thermal fleece layer of the upper side splicing pieces of the front and rear trouser pieces are cut so that the warp and weft directions of the cloth are consistent with the horizontal and vertical directions of the splicing pieces, which will not affect the elasticity of the fabric, thereby achieving the application effect.

[0043] When cutting the knee windproof interlayer, draw the same outer edge pattern as the front trouser piece according to the required range of the front trouser piece knee, and draw the center line of the trouser piece on the knee windproof piece pattern. The length of the side sewn with the outside of the trouser piece is longer than the length sewn with the inside of the trouser piece. Take a square piece of nylon cloth and overlap the 45° diagonal line with the trouser center line on the knee windproof piece. This strict cutting method can make the bias-cut knee windproof piece have stretch elasticity.

[0044] Stitching:

[0045] When sewing the upper side splicing piece of the inner thermal fleece layer to the main body of the trouser piece, first use a flat-bed sewing machine to make an initial connection with a narrow seam, and then use a four-needle six-thread press seam with a wide stitch for a second time, so that the narrow seam edge is completely pressed into the stitch, and the narrow seam cloth edge is covered by the stitch. The seams are flat, beautiful, and comfortable, and the seams do not exceed the thickness of the fabric, and the two different fabrics are perfectly integrated.

[0046] The outer windproof layer trouser body is connected to the upper side splicing piece. The trouser body has low elasticity and the splicing piece has high elasticity. When sewing, the low-elastic trouser body is placed on the high-elastic fabric and sewn once with a flat-bed sewing machine, with the low-elastic fabric on top. The sewing speed of the high-elastic fabric can be controlled during sewing, and wrinkles caused by sewing fabrics with different elasticity will not be generated. The secondary sewing uses four-thread hemming to reinforce the flat seam traces.

[0047] The knee windproof interlayer is sewn to the outside of the inner thermal insulation fleece layer or the inside of the outer windproof layer, the long side of the knee windproof piece is sewn together with the outside of the front and back pieces of the trouser piece, and the short side of the knee windproof piece is sewn to the inside of the front and back pieces of the trouser piece at the same time, and the oblique straight lines or oblique arcs connecting the two sides of the knee windproof piece are connected to the main body of the front trouser piece with a "Z"-shaped zigzag seam. The "Z"-shaped zigzag seam has a firm stitch and is also stretchable and shrinkable.

[0048] like Figure 3 As shown, the length of the pants can be adjusted at the bottom, and the inner thermal fleece layer is 8-10cm longer than the outer layer at 11 of the trouser legs of the thermal pants. The front and back trouser pieces of the inner thermal fleece layer are narrowly sewn with a flat sewing machine, and the seam edge of the narrow sewing is completely wrapped in the stitching of four needles and six threads for the second time. The fabric sewn twice is firm, flat, beautiful and comfortable. The inner and outer trouser seams are reinforced with three points of horizontal reinforcement lines at 0.2cm above the lower edge of the inner and outer trouser seams. The reinforcement lines are perpendicular to the inner and outer trouser seams, and a reinforcement line is sewn every 2cm from 0.2cm to the top, and 4-5 pairs are sewn symmetrically. The color of the reinforcement line is different from the color of the vertical line of the trouser seam, so that it is easy to refer to when cutting off the excess trouser length. Cut off the excess trouser length below the reinforcement line, so that the vertical seams of the front and back pieces of the trousers will not come loose.

[0049] The inner and outer trouser bodies are seamed inside and outside the outer windproof layer, and the hems are dotted with the inner warm fleece layer. A bartacking machine is used to only make dot connections on the seams, which will not affect the stretchability of the low-elastic fabric and increase the resistance to putting on and taking off.

[0050] The characteristics of the thermal pants of the present invention are:

[0051] 1. The upper side splicing pieces of the front and back trouser pieces of the thermal pants are made of thin high-elastic fabric on the outside and high-density velvet knitted fabric on the inside. The connection part with the main body of the front trouser piece is from the center line of the front trouser piece to the outer trouser seam on the outside of the trouser piece, and the lower end is the length to the horizontal crotch line. This design is both beautiful and practical. This part does not require high wind and cold protection, and can be covered by winter cotton clothes. The inner and outer elastic design makes the abdomen feel free from tightness when sitting, and the elastic part of the waistline can help the less elastic parts to achieve no obstacles when putting on and taking off. The present invention selects several fabrics to splice to make a pair of thermal pants, which can meet the needs of different parts and achieve better cold-proof effect while being comfortable to wear.

[0052] 2. The inner and outer fabrics of the main pants have a certain effect in blocking wind and cold. Low elasticity will make the fiber tissue density higher, and when stretched, it will not enlarge the gaps between tissues, making it easy for wind and cold to invade the skin.

[0053] 3. The lining of the trouser body is extended beyond the trouser surface. The lining has the characteristics of not curling or unraveling. The stitches are reinforced every two centimeters at the inner and outer seams, and the two sides are sewn symmetrically, so that people with the same hip circumference but different leg lengths can share the same style. People with different leg lengths can cut off the excess trouser legs below the trouser opening according to the required trouser length. The outer fabric of the trousers and the lining are connected at the outer corners of the trousers to prevent the outer fabric from running through. There is no outer fabric at the ankles, so there will be no large friction when wearing.

[0054] 4. The windproof layer of the knee is made of high-density nylon, which is thin and tight, and will not make the knee feel heavy. It can also be windproof. It is a fabric so it has a certain breathability. It is connected to the inner side of the outer trouser fabric or the outer side of the warm fleece fabric with a "Z" zigzag seam. It belongs to the ribbed fabric and has no elasticity in both horizontal and vertical directions. When the ribbed fabric is inelastic in both horizontal and vertical directions, the bias cut will produce a certain elasticity. After being sewn with the trouser body, such elasticity can maintain the same micro-elasticity as the lining fleece and the outer fabric. There is a certain stretch when the knee is bent, so that the human body will not feel tight and uncomfortable. The outer side of the front nylon windproof layer is long in order to increase the windproof area. When the human body is outdoors in winter, the front and side are sensitive to cold wind, while the inner side of the legs is not sensitive to cold wind from the left and right. Therefore, the inner nylon windproof layer should be shorter than the outer side, so that the line connecting the inner and outer sides is a diagonal line, which is more stable than the direct line and will not bulge when stretched.

[0055] The above embodiments are only used to illustrate rather than limit the technical solutions of the present invention. Although the above embodiments describe the present invention in detail, relevant technical personnel in the field should understand that the present invention can be modified or equivalently replaced, but any modification and partial replacement that does not depart from the spirit and scope of the present invention should be included in the scope of the claims of the present invention.
