The warm pants are necessary winter clothes, particularly for people with knee arthritis, knee pain can occur if the people fail to make leg warm in time temporarily in autumn and winter, and the pain disappears after protection. There are many medical reports that cold wind and cold in winter can actually aggravate pain in knee joints, although it cannot be directly explained as a main factor directly causing arthritis.

At present, most winter protection products on the market are high-elastic knitted outer fabrics and inner velvet fabrics with rich knitting elasticity. The cold-resistant leg mask has good shape following degree, but is tightly hooped on the leg to make people who are afraid of cold more cold, and cold wind and cold air directly push the skin; when the elasticity of the inner and outer sides of the cold-proof products is enlarged, gaps among fibers are enlarged, so that cold-proof and warm keeping are influenced to a certain extent. Still another outer fabric for winter warm-keeping products has no air permeability, and sweat and air naturally breathed by a body cannot be discharged when the garment is worn, so that the interior of the garment has a damp feeling. The traditional cotton-padded trousers are warm-keeping and breathable, but have no elasticity, are not attractive when being worn, and have poor comfort and shape following degree, so that the development of the warm-keeping trousers which can keep warm and can also be breathable and have certain elasticity is needed to improve the comfort. Therefore, it is a research object of the industry to find the best insulating material and method in winter and to make warm-keeping trousers which are warm-keeping, not bulky and beautiful and slim.

The inner and outer stitches are reinforced at the 0.2cm position on the lower edges of the inner and outer stitches of the inner thermal insulation velvet layer by using transverse reinforcing lines at three points, the reinforcing lines are vertical to the inner and outer stitches, reinforcing lines are sewn upwards from the 0.2cm position of the bottom edge of the trousers every 2cm and every 4-5 pairs of reinforcing lines are sewn symmetrically. The reinforcement lines are of a different color than the vertical lines of the seams.

The cutting method of the knee windproof interlayer comprises the following steps: the cutting mode of the windproof interlayer (nylon cloth) is oblique cutting, firstly, a knee paper pattern is made, namely, the knee part of the front trousers piece is cut to be used as the knee paper pattern, the length of the edge corresponding to the outer sewing line is larger than that of the edge corresponding to the inner sewing line, the two edges are connected by oblique lines or arc lines, and the central line of the front trousers piece is drawn; then, a square cloth is taken, two adjacent sides of the square respectively correspond to the radial direction or the latitudinal direction of the cloth, a diagonal line is drawn, a knee paper sample is placed on the cloth, the central line of the front piece on the paper sample is aligned with the diagonal line of the square cloth, and the fabric required by the knee is cut according to the paper sample. The radial direction or the latitudinal direction (transverse direction and longitudinal direction) of the windproof interlayer cloth has no elasticity, and the windproof interlayer cloth can generate certain elasticity by bias cutting.

The invention has the advantages that:

the upper side splicing pieces of the outer windproof layer and the inner warm-keeping velvet layer of the trousers have the same elasticity inside and outside, the elasticity is rich, the increase of waistline, abdominal girth and hip girth does not cause tightening feeling when a human body sits and stands, and all elastic interfaces of the waist also increase the girth and reduce the friction force when the human body wears and takes off, so that the obstruction is prevented. The outer windproof layer and the inner warm-keeping velvet layer have low elasticity inside and outside the main trouser body, have double barrier function on wind prevention, and simultaneously have certain function on internal temperature loss. The elasticity of the low-elasticity knitted velvet fabric and the low-elasticity woven fabric can meet the requirement of daily activities, and meanwhile, the gaps between the transverse and longitudinal fibers cannot be enlarged when the low-elasticity fabric of the inner and outer main trousers bodies are stretched, so that the trousers are windproof, cold-resistant and warm-keeping and simultaneously meet the requirement of warm-keeping trousers.

The knee windproof interlayer forms secondary reinforcement between two layers of main trouser surfaces, the knee is prevented from being invaded by external cold wind, the side length of the knee windproof piece sewn on the outer trouser edge is larger than that of the knee windproof piece sewn on the inner trouser edge so as to increase the wind-proof area of the knee, the outer sides of the left leg and the right leg are sensitive to the cold wind, so that the secondary wind-cold-proof capacity is increased, the left leg and the right leg are mutually blocked and are insensitive to stimulation of the cold wind in the inner side of the knee, the side length reduction in the inner side of the knee windproof piece also aims to enable the material degree of the upper line and the lower line connecting the two sides of the knee windproof piece to be fixed, the knee is often bent, the upper part and the lower part. The fabric is thin in the breathable windproof layer and thick in warm velvet.

Adjustable trouser legs, interior thermal insulation fine hair layer length goes out outer windproof layer, and different inner length make in wear the trousers also have and wear the trousers outward and keep cutting trousers length according to leg length weak point, and the short fat people and thin high people are surrounding with buttockss, use a number with the waistline under, can not have the not enough trouser legs of high, the awkwardness of the people's trouser legs overlength of height weak point, adjust the trouser legs by oneself and changed in the past inside and outside the trousers face an organic whole can not subtract unnecessary trouser legs, can cut out the difficult situation of sewing. Because special machines are needed, the technical problem cannot be solved by sewing the trouser leg bottom edges in the ordinary daily life, and the design of the invention only needs the wearer to cut off the redundant trouser length under the reinforcing line.

The upper end of the splicing piece at the upper side of the back trouser piece is a partial back waist line at the outer side of the central line of the back trouser piece, the outer side is an outer side waist part (partial outer suture line), the inner side is a straight line between the intersection point of the back waist line and the central line of the back trouser piece and a point which is higher than the hip line 8 on the central line of the back trouser piece, and an arc line between the point which is higher than the hip line 8 on the central line of the back trouser piece and a point which is lower than the transverse crotch line 9 on the outer suture line of the back trouser piece. The part of the back trouser piece except the splicing piece at the upper side of the back trouser piece is a main body of the back trouser piece.

The knee of the front trousers piece is also provided with a reinforced windproof interlayer 10 which is positioned between the outer windproof layer and the inner warm-keeping velvet layer, two edges of the windproof interlayer 10 are respectively sewed on the outer sewing line 5 and the inner sewing line 6, the side length of the outer side is greater than that of the inner side, the other two edges are straight lines or arc lines, the shape is similar to a trapezoid, and the included angle between the central line 3 of the front trousers piece and the radial direction or the latitudinal direction of the interlayer fabric is 45 degrees.

At the bottom of trousers 11 of the warm trousers, the length of the inner warm-keeping velvet layer is longer than that of the outer windproof layer, usually the inner warm-keeping velvet layer is 8-10cm longer than the outer windproof layer, reinforcing lines 12 are arranged at intervals of 2cm on the longer inner warm-keeping velvet layer, and reinforcing lines 12 are symmetrically arranged on the inner seam line and the outer seam line of the front trousers piece and the rear trousers piece and are arranged in 4-5 pairs. People with different heights and long legs can cut according to the need by referring to the reinforcing line 12 and cut off redundant trouser legs. The bottom end of the outer windproof layer is sewn on the inner warm-keeping velvet layer. The length of the trousers can be adjusted, the inner velvet material of the inner warm-keeping velvet layer has the characteristics of no loose edge and no curling after being compounded in a low-elasticity and high-density mode, and the shape of the bottom of the trousers made of the inner velvet can not be changed after the excess length of the trousers is cut off.

The inner warm-keeping velvet layers of the front and rear trouser piece main bodies adopt low-elasticity high-density knitted swinging particle composite velvet; the inner warm-keeping velvet layer of the splicing piece on the upper sides of the front and the back trousers pieces adopts silver fox velvet with rich elasticity. The elasticity of the silver fox fleece is larger than that of the shake grain composite fleece, and the silver fox fleece and the shake grain composite fleece are made of materials with equal thickness.

The outer windproof layer of the front and rear trouser piece main bodies is made of woven polyester plus spandex fabric or polyamide plus spandex fabric, for example, polyester 200D four-side stretch fabric, and the outer windproof layer of the splicing piece on the upper sides of the front and rear trouser pieces is made of knitting fabric with rich elasticity, for example, swimwear fabric, so that when a human body moves, the fiber gap can not be enlarged, and the windproof, cold-proof and warm-keeping effects are not influenced. The inner warm-keeping velvet layer and the outer windproof layer of the splicing pieces on the upper sides of the front and the back trousers pieces are made of fabrics with rich elasticity, so that the front and the back trousers pieces are stretched uniformly.

The knee strengthening and windproof interlayer 10 is made of high-density nylon cloth, and the nylon cloth has no elasticity in the radial direction or the latitudinal direction (transverse and longitudinal directions). The nylon cloth is cut in an oblique mode, the included angle between the radial direction or the weft direction of the nylon cloth and the central line of the front piece of trousers is 45 degrees, and the nylon cloth generates certain elasticity through oblique cutting, namely the nylon cloth has certain elasticity when being stretched on a 45-degree diagonal line on a square fabric with the same width and length. When the nylon cloth is simultaneously stressed and stretched with the inner and outer trouser bodies, the nylon cloth keeps the same tension, and the nylon cloth is thin and does not have marks on the surface of the outer layer of the trousers.

Cutting:

as shown in fig. 2, the cutting manner of the windproof interlayer 10 (nylon cloth) is bias cutting, firstly, a knee paper pattern is made, namely, the knee part of the front piece of the trouser leg is cut to be used as the knee paper pattern, the length of the edge corresponding to the seam of the outer trouser leg is larger than that of the edge corresponding to the seam of the underpants, the two edges are connected by oblique lines or arc lines, and the central line of the front piece of the trouser is drawn; then, a piece of square high-density nylon cloth with the same length and width is taken, a diagonal line is taken to draw a straight line, the line is matched with the central line of the trousers, when the outer fabric is cut, a knee paper pattern is taken down and placed on the diagonal high-density nylon, so that the central line of the outer surface of the trousers is aligned with the opposite angle of the square high-density nylon cloth, and the fabric required by the knee is cut down. The knee required by cutting the trousers body with the paper sample can cut the required cloth piece by the nylon fabric in an oblique way, and the upper oblique arc line and the lower oblique arc line can increase the tensile property again, so that the legs can not feel strange when the trousers are worn. The outer side is longer than the inner side for increasing the wind protection of knees, and the upper end and the lower end are connected with the outer fabric or the inner fabric of the trousers by a Z-shaped zigzag seam. Compared with the straight line, the curve has certain stretchability, and can reinforce without influencing the elasticity of the bias-cut knee pad layer.

The upper splicing pieces of the front and the rear trousers pieces, the outer windproof layers and the inner warm-keeping velvet layers of the main bodies of the front and the rear trousers pieces are obtained by cutting according to the design of the warm-keeping trousers, wherein the warp direction and the weft direction of the cloth are consistent with the horizontal direction and the longitudinal direction of the splicing pieces when the outer windproof layers and the inner warm-keeping velvet layers of the upper splicing pieces of the front and the rear trousers pieces are cut, so that the elasticity of the fabric is not influenced, and the application effect is achieved.

When the knee windproof interlayer is cut, the outer edge paper pattern which is the same as that of the front trousers piece is drawn according to the range required by the knee of the front trousers piece, meanwhile, the central line of the trousers piece is also drawn on the knee windproof interlayer paper pattern, and the length of the side length which is sewed with the outer side of the trousers piece is larger than that which is sewed with the inner side of the trousers piece. A45-degree diagonal line of a square nylon cloth is overlapped with the central line of trousers on the knee windproof piece, so that the knee windproof piece which is cut obliquely can have tensile elasticity only by a strict cutting method.

And (3) sewing:

when the splicing piece on the upper side of the inner warm-keeping velvet layer is sewn with the trouser sheet main body, the flat sewing machine is firstly used for primary connection, and then four-needle six-thread seam pressing of the wide stitch seam is used for two times, so that the narrow seam edge is completely pressed and sewn in the stitch seam, the narrow seam cloth edge is covered by the stitch seam, the sewing position is flat, attractive and comfortable, the sewing does not exceed the cloth thickness, and two different fabrics are perfectly combined into a whole.

Outer windproof layer trousers piece main part is connected with upside concatenation piece, and the trousers piece main part has low elasticity, and the concatenation piece has high-elasticity, puts on high-elasticity surface fabric when making up low elasticity trousers piece main part, once sews up with the lockstitch machine, and low elasticity surface fabric can control high-elasticity surface fabric when making up and sews into speed on it, can not produce different elasticity surface fabrics and sew up produced fold, and the secondary is sewed up and is overlooked and consolidate in lockstitch seam stitch department with the four-wire overlock.

The knee is prevent wind the outside of intermediate layer seam including cold-proof fine hair layer or the inboard on outer windproof layer, and the long limit of knee windproof piece is sewed together with the sewing in the front and back piece outside of trousers piece, and the minor face of knee windproof piece is sewed up with the piece front and back piece inboard simultaneously, connects oblique straight line or oblique pitch arc on knee windproof piece both sides and adopts "Z" word zigzag seam to be connected with preceding trousers piece main part, and "Z" word zigzag seam stitch is firm, has tensile contractibility simultaneously.

As shown in figure 3, the length of the trousers can be adjusted at the lower end of the trousers, the outer layer of the inner warm-keeping velvet layer is 8-10cm longer than the bottom of the trousers 11 of the warm-keeping trousers, the front and the rear trousers pieces of the inner warm-keeping velvet layer are narrow-sewed by a flat sewing machine, and the first narrow-sewed edge is completely wrapped in the four-needle six-thread stitch. The fabric sewn twice is firm, flat, attractive and comfortable. And (4) reinforcing the inner and outer trouser seams at a position of 0.2cm above the lower edge of the inner and outer trouser seams by using transverse reinforcing lines at three points. The reinforcing lines are perpendicular to the seams between the inner and outer trousers, and the reinforcing lines are sewn at the position of 0.2cm upwards for 4-5 pairs every 2 cm. The color of the reinforcing lines is different from that of the vertical lines of the trousers seams, so that the redundant trousers lengths are easy to refer to when being cut off, and the redundant trousers lengths are cut off below the reinforcing lines, so that the vertical lines of the front and the rear pieces of the trousers are not scattered.

The inner and outer trousers bodies are sewn with the upper leg opening edge on the inner and outer windproof layers and are in point-like overlapped seam with the inner warm-keeping velvet layer, and a bartack sewing machine is adopted, only the upper point connection of the seam is made, thus the stretching of the low-elasticity fabric is not influenced, and the putting-on and taking-off resistance is increased.

The warm-keeping trousers of the invention have the characteristics that:

1. this cold-proof trousers's preceding back trousers piece upside splicing piece, outer surface fabric is high-elastic thin surface fabric, the lining is high density fine hair knitted fabric in the inside, the connection position with preceding trousers piece main part be from the outer trousers seam in preceding trousers piece central line to the trousers piece outside, lower extreme length to the crotch line on, this kind of design is not only pleasing to the eye but also practical, this position is not high to preventing wind cold requirement, there is winter cotton-padded clothes to shelter from, the belly does not have to be felt when the interior outer layer elasticity design makes the sitting upright, accessible when the position that elasticity is few can be helped to the elasticity part of waist portion realizes wearing to take off. The invention selects several fabrics to splice into the warm-keeping trousers, which can meet the requirements of different parts and achieve better cold-resisting effect while being comfortable to wear.

2. The fabric inside and outside the main pants body has certain wind cold blocking effect, the low elasticity can make the density of fibrous tissues large, and gaps among the tissues cannot be enlarged during stretching so that wind cold can easily invade the skin of the body.

3. The down in the trousers body is longer than the surface of the trousers, the down has the characteristic of no hemming and no loose edge, the stitch is reinforced at every two centimeters at the two sewing lines inside and outside, the two sides are symmetrically sewed, thus people with the same hip circumference and different leg lengths share one style, and the redundant bottom of trousers are cut off at the lower part of the opening of the trousers according to the required length of trousers. The outer fabric of the trousers is in point connection with the inner velvet at the outer trouser corners, so that the outer fabric of the trousers is not easy to run, and the outer fabric of the trousers does not have the ankle part and can not generate large friction force when being worn.

4. The windproof layer of the knee is made of high-density nylon, is thin and compact, does not cause the knee to feel thick, can prevent wind, is a fabric with a certain ventilation function, is connected to the inner side of the outer trousers fabric or the outer side of the warm velvet fabric by Z-shaped zigzag seams, belongs to prismatic woven fabric, and has no elasticity in the transverse direction and the longitudinal direction. When the edge fabric is not elastic in both the transverse direction and the longitudinal direction, the bias cut can generate certain elasticity, and the elasticity can keep the common micro-elasticity with the inner velvet and the outer fabric after being sewn with the trousers body and can stretch to a certain degree when the knees are bent, so that the human body does not feel strange and uncomfortable. The outer side of the nylon wind-proof layer of the front piece is long so as to increase the wind-proof area, when a human body is outdoors in winter, the front face and the side face are sensitive to cold wind, and two legs on the inner sides of two opposite legs block each other and are insensitive to the cold wind coming from the left and the right. Therefore, the inner nylon windproof layer is shorter than the outer nylon windproof layer, lines connecting the inner side and the outer side are oblique lines, the oblique lines are stronger than direct stability, and the nylon windproof layer cannot bulge when being stretched.
