Description

Technical Field

[0001] The invention relates to the field of clothing manufacturing, and in particular to a pair of trousers with a light and thin elastic waist lining, trousers and a preparation method thereof. Background Art

[0002] As men age and their living standards improve, they develop a beer belly or gain weight. This is especially true for business people who sit for long periods without exercising, which results in increased belly fat. Since their leg length is fixed, it is difficult for them to buy pants that fit them. Even if they do, they may no longer fit as their body shape changes. Even if they can fit, the belly fat will stick out when they squat, bend over, or eat. Furthermore, since the waistband of trousers is fixed and upright (suit trousers require a waistband that remains upright for aesthetic reasons), it is very uncomfortable to wear them without undoing the belt and buttons. Undoing the belt and buttons (i.e., unbuttoning the trousers) is very inconvenient and indecent for business people.

[0003] In order to solve the above problems, existing clothing manufacturing companies have developed the following waistbands to solve the problem of being unable to wear pants due to body deformation, specifically as follows: (1) using an adjustable hidden button method, that is, built-in adjustable serrated hidden buttons on the left and right sides of the waistband, the hidden button has a certain length, which is adjusted before wearing and is in a loose state. Although this method solves the problem that the length of the pants is fixed and the wearer cannot wear it as the body changes, it is still inconvenient to adjust it. It cannot be adjusted freely with the hips or belly, and the adjustable hidden button increases the overall thickness of the waistband, resulting in the entire waistband bulging and poor appearance; (2) sewing a thick piece of cloth inside the waistband, This fabric is woven from polyester and has a certain degree of elasticity after being wrapped. However, market feedback indicates that this type of product only works when purchased. After wearing for a period of time or washing, its elasticity becomes insufficient, making it difficult to restore the pants to their original position. More importantly, it is easily deformed and has poor aging resistance. It deforms after washing or sweating, which ultimately causes the originally flat waistband to be more prone to wrinkling and edge distortion (and a flared, wavy waistband edge) after the addition of this fabric. Furthermore, the production process is difficult, and there is no positioning reference when wrapping the outer fabric of the waistband. The folded edge of the ironed surface is uneven and difficult to form a straight line, which reduces the overall aesthetics.

[0004] In summary, the existing waistbands still need to be further improved and enhanced. Summary of the Invention

[0005] The purpose of the present invention is to overcome the above-mentioned defects or problems existing in the background technology, and to provide a waistband, trousers and a preparation method with a thin and light elastic waist lining, which has a simple structure, is easy to make, easy to implement and low in cost, and solves the problem that the existing waistband cannot simultaneously meet the requirements of maintaining uprightness, being thin and beautiful, and freely adjusting the waistband size according to changes in body shape.

[0006] To achieve the above object, the present invention adopts the following technical solutions:

[0007] A trouser waist with a light and thin elastic waist lining, the trouser waist comprising a waist cloth, an elastic lining cloth and an elastic rubber layer;

[0008] a loin cloth configured as a loin cloth made of a knitted fabric or a woven fabric having elasticity;

[0009] A stretch interlining comprising at least two stretch connecting regions and an stretch supporting region, the stretch supporting region being located between the two stretch connecting regions; the stretch supporting region being woven from a polyester / nylon blended weft and spandex warp, and having a width that is 0.1 to 0.5 cm less than the waistband width; the stretch connecting regions on either side of the stretch supporting region being woven from nylon weft and spandex warp; and a plurality of stretch ribs being provided at the interlaced locations of the warp and weft in the stretch supporting region and the stretch connecting region, with each stretch rib being arranged along the warp direction.

[0010] The elastic adhesive layer is coated on the elastic connection area and the elastic support area and is used to adhere the elastic lining fabric to the waist cloth.

[0011] Furthermore, the elastic supporting area and the elastic connection area are connected as a whole via a transition area, and the transition area is composed of a plurality of parallel wefts, and the wefts are made of nylon.

[0012] Furthermore, the warp threads of the elastic support area are formed by spandex yarns wound around the periphery of the elastic ribs; the weft threads are formed by nylon yarns wound around polyester yarns, and are interwoven with the warp threads in both vertical and horizontal directions.

[0013] Furthermore, in the elastic support area, at least two weft threads form a weft thread bundle interwoven with a warp thread, and the spacing between two adjacent warp threads is 0.04-0.06 cm, and the spacing between two adjacent weft thread bundles is 0.01-0.02 cm.

[0014] Furthermore, the width of the elastic support area is 3.6-4.0 cm.

[0015] Furthermore, the warp threads in the elastic connection area are formed by spandex yarns wound around the periphery of the elastic ribs and interwoven with nylon weft threads in both directions; and the spacing between two adjacent warp threads in the elastic connection area is 0.15-0.2 cm.

[0016] Furthermore, the width of the transition area is 0.25-0.3 cm.

[0017] The utility model relates to a pair of trousers with a light waist, comprising a trouser body and a trouser waist. The trouser waist is further covered with a waist cloth, an elastic lining cloth and an elastic rubber layer. The elastic lining cloth is adhered to the waist cloth through the elastic rubber layer and is sewn together with the trouser body.

[0018] A method for preparing thin-waisted trousers, comprising the following steps:

[0019] Step 1: Use nylon yarn to wrap around polyester yarn to form the weft yarn; use spandex to wrap around the elastic reinforcement to form the warp yarn; both yarns are used as the yarn material for weaving the elastic support area;

[0020] Step 2: Select nylon as the weft; select spandex yarn and wrap it around the outer periphery of the elastic ribs as the warp. Both will serve as the wire material for braiding the elastic connection area.

[0021] Step 3: Weaving the yarns in the warp direction using a warp knitting machine; wherein the spacing between the two warp threads in the elastic connection area is 0.15-0.2 cm, and the width of each elastic connection area is between 0.25-0.3 cm; the transition area is extended to the elastic support area and connected by nylon; the elastic support area is woven in the warp direction and the two weft threads are formed into a weft bundle and then woven with the warp threads, wherein the spacing between the two warp threads is 0.04-0.06 cm, and the spacing between the two weft bundles is 0.01-0.02 cm;

[0022] Step 4: Apply a layer of elastic adhesive layer on the back of the woven elastic lining fabric, the thickness of the elastic adhesive layer is 0.01-0.03 cm; and dry it to set it for later use;

[0023] Step 5: Cut the waist cloth and trouser body fabric pieces of a predetermined length and width. The waist cloth is configured as a waist cover cloth and a waist lining cloth;

[0024] Step 6: Lay the waist fabric flat and fix it to the elastic lining fabric coated with an elastic adhesive layer, and perform high-temperature shaping on a high-temperature ironing press to melt the elastic adhesive layer on the elastic lining fabric and then evenly bond it to the waist fabric. The heating temperature is 145-150°C and the shaping pressure is 0.25-0.3 MPa. After shaping, the elastic support area is the width of the trouser waist.

[0025] Step 7: Sew the waist lining along the transition area with the waist cover fabric;

[0026] Step 8: Fold the waist lining sewn together inward, and use the transition area as the upper edge of the waistband to iron and shape it to form a finished waistband;

[0027] Step 9: Sew the other edge of the waist fabric to the trouser body fabric, leaving a seam space after sewing;

[0028] Step 10: Fold the seam toward the position between the waist fabric and the waist lining, and fold the waist lining inward as well. Then, sew the trouser body, seam, and waist lining into one piece from the front of the waist fabric and along the lower edge of the waistband.

[0029] From the above description of the present invention, it can be seen that compared with the prior art, the present invention has the following beneficial effects:

[0030] (1) The present invention provides a trouser waistband, trousers and a preparation method with a light and thin elastic waist lining, which has a simple structure, is easy to make, easy to implement and has low cost, and solves the problem that the existing trouser waistband cannot simultaneously meet the requirements of maintaining uprightness, lightness and beauty, and at the same time being able to freely adjust the size of the trouser waistband according to changes in body shape; the present invention sets an elastic lining cloth in the waist cloth, and the elastic lining cloth is woven by interlacing the weft yarn of polyester and nylon blend and the warp yarn made of spandex to form an elastic support area, and the elastic support area can not only achieve the force support in the weft direction after weaving, but also achieve The elastic deformation in the warp direction is not only light and thin, but also weighs only 13g after weaving. It does not affect the simple and upright beauty of the waistband. In addition, the elastic connection area is sewn with the waist lining, and the elastic support area and the elastic connection area are shaped to ensure that the entire waistband can maintain its shape after washing or sweating, without any flared distortion at the edges. It is especially suitable for high-end trousers. After meals or during various exercises, it can adjust with the changes in the belly (waistband) and still maintain a straight feeling, which is deeply favored by business people.

[0031] (2) The present invention also provides a transition area, which makes it easier to shape the waist fabric when it is folded inward or sewn. More importantly, it also provides a guiding function, making it easier to keep the edge straight whether it is shaping or sewing. Since the waist fabric is made of elastic knitted or four-sided elastic woven fabric, the above situation is very likely to occur during the sewing or shaping process. The ingenious design of this transition area solves the above problem and reduces the difficulty of production and sewing.

[0032] (3) The present invention winds spandex yarn around the elastic ribs as the warp, thereby increasing the elasticity of the overall waistband and maintaining the elastic effect after long-term use; it is not easily degraded by washing or perspiration, thereby increasing the service life;

[0033] (4) In the present invention, at least two wefts form a weft bundle interwoven with a warp, and the spacing between two adjacent warps is 0.04-0.06 cm, and the spacing between two adjacent weft bundles is 0.01-0.02 cm; the overall strength is maintained by the weft bundle, thereby enhancing the upright feeling of the entire trouser waist;

[0034] (5) The present invention combines a thin waistband with trousers, which not only maintains the upright and straight appearance of the trousers, but also solves the problem of being unable to wear them due to belly changes or body deformation. These two mutually exclusive contradictions are perfectly resolved and combined. More importantly, after pulling tests and aging tests, the waistband of the present invention is not prone to flaring, making it very suitable for use in high-end quality trousers.

[0035] (6) The preparation method of the present invention has few steps and simple process, and the thin waist lining can be easily placed in the waistband of the pants, which not only simplifies the process difficulty and reduces the cost, but also greatly improves the quality of the waistband of the pants, ensures the overall aesthetics, and makes it flat and smooth.

[0049] See also Figure 1-3 The trouser waist with a light and thin elastic waist lining of the present invention comprises a waist cloth 1, an elastic lining cloth 3 and an elastic rubber layer 6;

[0050] The waist cloth 1 is configured as a waist cloth 1 made of a knitted fabric or an elastic woven fabric. It should be noted that the waist cloth 1 of the present invention includes a waist surface cloth 11 and a waist lining cloth 12. Of course, the waist surface cloth 11 can also be folded in half and the other side of the waist surface cloth 11 can be used as the waist lining cloth 12.

[0051] Elastic lining 3, which is bonded to the waist cloth 1;

[0052] The elastic lining fabric 3 includes at least two elastic connection areas 31 and an elastic support area 32, wherein the elastic support area 32 is located between the two elastic connection areas 31;

[0053] The elastic support area 32 is woven from weft yarns 321 of a polyester and nylon blend and warp yarns 322 of spandex. The width of the elastic support area 32 is 0.1 to 0.5 cm smaller than the waistband width, preferably smaller than 0.2 cm. It should be noted that the warp yarns 322 and weft yarns 321 described in the present invention refer to the weft yarns 321 along the width of the waistband and the warp yarns 322 along the length. This setting is because it is easier to weave and form during the weaving process, so the width direction is defined as the weft direction, and the length direction is defined as the warp direction.

[0054] The warp threads 322 of the elastic support region 32 are formed by spandex yarns wound around the outer periphery of the elastic ribs 4 (it should be noted that the diameter of the elastic ribs 4 in the elastic support region 32 is larger than that of the elastic ribs 4 in the elastic connection region 31, thereby enhancing the elastic deformation capability of the elastic support region along the warp direction. The elastic connection region 31 also experiences less positional deformation and is less susceptible to edge distortion). The weft threads 321 are formed by nylon yarns 321A wound around polyester yarns 321B and interwoven with the warp threads 322 in both the vertical and horizontal directions. The width of the elastic support region 32 is 3.6-4.0 cm.

[0055] The elastic connection areas 31 located on both sides of the elastic support area 32 are woven from nylon weft yarns 311 and spandex warp yarns 312. It should be noted that the warp yarns 322 of the elastic connection areas 31 of the present invention are spandex yarns 322A wound around the outer periphery of the elastic ribs 4 and interwoven with the nylon weft yarns 311 in both directions. Furthermore, the spacing between adjacent warp yarns 322 in the elastic connection areas 31 is 0.15-0.2 cm.

[0056] A plurality of elastic ribs 4 are provided at the interlaced positions of the warp 322 and the weft 321 on the elastic support area 32 and the elastic connection area 31, and each elastic rib 4 is arranged along the direction of the warp 312;

[0057] The elastic support area 32 and the elastic connection area 31 are connected to each other through a transition area 33. The transition area 33 is composed of a plurality of parallel wefts 331, and the wefts 331 are made of nylon. The width of the transition area 33 is 0.25-0.3 cm.

[0058] The elastic rubber layer 6 is coated on the elastic connection area 31 and the elastic support area 32 and is used to bond the elastic lining fabric 3 to the waist cloth 1 .

[0059] More specifically, at least two wefts 321 in the elastic support area 32 form a weft bundle interwoven with a warp 322 , and the spacing between two adjacent warp threads 322 is 0.04-0.06 cm, and the spacing between two adjacent weft bundles 321 is 0.01-0.02 cm.

[0060] Specific implementation method, such as Figure 1-7 As shown, the present invention takes a pair of trousers with a light waist as an example, which includes a trouser body 5 and a trouser waist 7. The trouser waist 7 includes a waist cloth 1, an elastic lining 3 and an elastic rubber layer 6. The elastic lining 3 is glued to the waist cloth 1 through the elastic rubber layer 6 and is sewn together with the trouser body 5.

[0061] The actual preparation method comprises the following steps:

[0062] Prepare the elastic interlining 3 by using warp knitting equipment for longitudinal and transverse weaving, specifically as follows: Figures 1 to 3 As shown,

[0063] Step 1: Nylon yarn 321A is wound around polyester yarn 321B to form weft yarn 321; spandex is used to wrap the elastic rib 4 and then form warp yarn 322; both yarns are used as the yarn material for weaving the elastic support area 32 and are reserved for subsequent weaving.

[0064] Step 2: Select nylon as the weft 311; select spandex yarn and wrap it around the outer periphery of the elastic rib 4 as the warp 312, and both will be used as the wire material for weaving the elastic connection area 31;

[0065] Step 3: The yarns are knitted longitudinally and transversely using a warp knitting machine, and knitted along the warp threads 322 to form a knitted fabric. The spacing between adjacent warp threads 322 in the knitted elastic connection region 31 is 0.15-0.2 cm, and the width of each elastic connection region 31 is between 0.25-0.3 cm. The transition region 33 directly transitions to and connects to the elastic support region 32 via a nylon weft thread 331, thereby connecting the elastic support region to the two elastic connection regions. The elastic support region 32 is knitted longitudinally and transversely, and the two weft threads 321A and 321B are formed into a weft bundle 321 and then knitted with the warp threads 322. The spacing between the two warp threads 322 is 0.04-0.06 cm, and the spacing between the two weft thread bundles 321 is 0.01-0.02 cm.

[0066] Step 4: Coat a layer of elastic adhesive layer 6 on the back of the woven elastic lining fabric 3. The thickness of the elastic adhesive layer 6 is 0.01-0.03 cm, preferably 0.015 cm. Then, dry and shape the elastic adhesive layer 6 for later use.

[0067] Step 5: Cut the waist cloth 1 and the trouser body fabric 5 to a predetermined length and width. The waist cloth 1 is configured into a waist cover fabric 11 and a waist lining fabric 12;

[0068] Step 6: Figure 4 、 5 As shown, the waist fabric 11 is laid flat and pre-fixed with the elastic lining fabric 3 coated with the elastic adhesive layer 6. The elastic adhesive layer 6 on the elastic lining fabric 3 is heat-melted and then evenly bonded to the waist fabric 11. The heating temperature is 145-150°C and the setting pressure is 0.25-0.3 MPa. After forming, the elastic support area 32 is the width of the trouser waist 7.

[0069] Step 7: Figure 6 As shown, the waist lining 12 is sewn together with the waist cover fabric 11 along the transition area 33;

[0070] Step 8: Fold the waist lining 12 sewn together inward (flipping inward here means turning the waist lining 12 to the back of the waist fabric 11), and iron and shape the upper edge of the waistband 7 along the transition area 33 to form a finished waistband 7;

[0071] Step 9: Sew the other edge (i.e., the lower edge) of the waist fabric 11 to the trouser body 5 together, leaving a seam space (the seam space here refers to the remaining fabric after sewing the two together, and the fabric here needs to be hidden to avoid affecting the aesthetics);

[0072] Step 10: Figure 7 As shown, the seam is folded toward the position between the waist fabric 11 and the waist lining 12, and after the waist lining 12 is folded inward, the trouser body 5, the seam and the waist lining 12 are sewn together from the front of the waist fabric 11 and along the lower edge of the waistband 7 to complete the production process of the entire thin waistband trousers. The whole process is simple, which reduces the difficulty of production. More importantly, the trousers are kept light and strong, and can have free horizontal stretch without distortion or wavy flared edges, breaking the difficulty of the existing three-dimensional appearance and lateral free deformation that cannot be achieved at the same time, and are both beautiful and practical.

[0073] The present invention provides a trouser waistband, trousers and a preparation method with a light and thin elastic waist lining, which has a simple structure, is easy to manufacture, easy to implement and has low cost, and solves the problem that the existing trouser waistband cannot simultaneously meet the requirements of maintaining uprightness, lightness and thinness, and at the same time being able to freely adjust the trouser waistband size according to changes in body shape; the present invention arranges an elastic lining fabric inside the waist cloth, and the elastic lining fabric is woven by interlacing weft yarns of a polyester and nylon blend with warp yarns made of spandex to form an elastic support area, and after the elastic support area is woven, it can not only achieve force support in the weft direction, but also achieve elastic deformation in the warp direction, and more importantly, it is light and thin, and the entire elastic lining fabric weighs only 13g after weaving, which is completely It does not affect the simplicity and upright beauty of the trouser waist. In addition, the elastic connection area is sewn with the waist lining, and the elastic support area and the elastic connection area are shaped to ensure that the entire trouser waist can still maintain its shape after washing or sweat immersion, and there will be no flared distortion at the edge. It is especially used in high-end trousers. After a meal or during various sports, it can change with the changes in the belly (waist cloth), and it also has a straight feeling, which is deeply favored by business people. The present invention also provides a transition area, which is easier to shape when the waist cloth is folded inward or sewn, and more importantly, it also provides a guiding effect. Whether it is shaping or sewing, it is easier to keep the edge straight. The elastic knitted or four-sided elastic woven fabric is used. The above situation is very likely to occur during the sewing or shaping process. The ingenious design of this transition area solves the above problem and reduces the difficulty of production and sewing. The present invention winds the spandex yarn around the elastic ribs as the warp, which increases the elasticity of the overall trouser waist and can maintain the elastic effect after long-term use; it is not easy to become ineffective due to washing or perspiration, and the service life is increased; in the present invention, at least two wefts form a weft bundle and are interwoven with a warp, and the spacing between adjacent warps is 0.04-0.06cm, and the spacing between adjacent weft bundles is 0.01-0.02cm; the weft bundle is used to maintain the elasticity of the trouser waist.

Step 7: Sew the waist lining along the transition area with the waist cover fabric; Step 8: Fold the waist lining sewn together inward, and use the transition area as the upper edge of the waistband to iron and shape it to form a finished waistband; Step 9: Sew the lower edge of the waist fabric to the trouser body fabric, leaving a seam space after sewing; Step 10: Fold the seam toward the position between the waist fabric and the waist lining, and fold the waist lining inward as well. Then, sew the trouser body, seam, and waist lining into one piece from the front of the waist fabric and along the lower edge of the waistband.
