Description

CROSS-REFERENCE TO RELATED APPLICATION

This application claims priority from CN Patent Application Serial No. 2014100309621, filed on Jan. 23, 2014, the entire contents of which are incorporated herein by reference for all purposes.

TECHNICAL FIELD

The invention is related to the push up jeans and a new production process thereof.

BACKGROUND OF THE INVENTION

Jeans has been one of fashionable clothing and very popular. People at different ages usually have jeans. Since the fabric of jeans is relatively hard, the cutting and styling can show the body shape. But for people with bigger hips, they wish to tighten up the hips to enhance the overall shape.
Jeans is divided to stretch and non-stretch, and most of them are cut to fit the body shape of lower body. However, for the stretch fabric, the body shape will not come out good for people with poor hip shape, and therefore, these people will choose the loose-fit jeans.
On the other hand, body shaping jeans are produced by sewing a separate elastic/stretching fabric onto the jeans for pushing up the hips effects. If additional fabric is sewn on the jeans, the consumer may feel uncomfortable since the sewn fabric is likely to be folded and moved. In addition, the sewn fabric can easily be dyed or may affect the pattern on the jeans during washing process.

SUMMARY OF THE INVENTION

The technical problem to be solved by this invention is to provide the pushup jeans and related production process. The structure is simple to use, and can improve the hip shape. Besides, the process is simple to use, and can increase the production efficiency, and reduce the problem of washing streaks during the washing process.
The above objective is achieved by the following technical solution:
The pushup jeans include jeans and fusible interlining. Each pant leg of jeans comprises a front panel and a back panel. The fusible interlining is fused onto the back panels and adhered close to the bottom and side of hip position; at the same time, fusible interlining is fused onto the inside of front panels and opposite to the fusible interlining of back panels. The fusible interlining has an arc-shaped portion, and the arc-shaped portion is recessed downwards. The outer edge of fusible interlining is aligned with the outer edges of the front panel and back panels. The length of fusible interlining is the distance from the crotch extending downwards 2-15 cm to the lower edge of waistband.
Preferably, one end of arc-shaped fusible interlining is located at the lower edge of the waistband, another end is equal to or higher than the crotch. The bottom of this portion can extend to thigh area.
In the production process of pushup jeans, the two legs of the pants are sewn together by front panel and back panels, and the fusible interlining is adhered to bottom and side of hips on the back panel by ironing; and the fusible interlining is disposed at a location within the front panel and opposite to the fusible interlining of the back panel. The steps for the process are as follows:
a) cutting the fusible interlining, the shape of fusible interlining being matched to the shape on the sewing thread location of pant legs;
b) laying the fusible interlining onto the panel, the outer edges of both the interlining and jeans panels being aligned;
c) turning the temperature of iron-pressing machine to 140° C.-160° C., and setting a constant temperature after heating;
d) adjusting the pressure parameter of the iron-pressing machine to 2-3.5 kg;
e) putting the lain fusible interlining and the panel together into the heated iron-pressing machine for iron-pressing; and
f) sewing the iron-pressed front and back panels to pants.
Preferably, the iron-pressing machine is a roller-type pressing machine.
Preferably, the iron-pressing time of the step e) is 10-17 seconds.
The beneficial effects of the invention are such: the shape and cutting of the fusible interlining designed in this invention is kept away from the position of the hips, such that the hip area is in the elastic fabric; the fusible interlining is used to reduce the elasticity of the stretch denim fabric for tightening up all around of bottom of hips, which enhances the whole body shape more effectively, and whole hips will become more rounded; front panel is also fused with the corresponding fusible interlining, which can effectively tighten up the whole thigh area; the ironing position of the fusible interlining is equal to or higher than the position of the crotch, which is able to tighten up on both sides of the thigh fat; the design with this production method can greatly improve the production efficiency because it does not need to be stitched by threads or any manual stitching, just need to press the fusible interlining tightly by iron-pressing; since the tolerance of the jeans and the fusible interlining are different, so, there is strict control for the pressure, temperature and time for this iron-pressing process, to avoid the damage for fusible interlining; for the jeans produced by such a method, washing streaks will not appear in the washing process, since the edges are smoothly combined with the jean and the interlining is thin, therefore, the pattern will not be affected during the washing process.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 2 is a reverse-side structural diagram of the back panels of the invention.

DETAILED DESCRIPTION OF THE INVENTION

In the following the invention will be further described in connection with the drawings.
As shown in FIG. 1, pushup jeans comprises jeans and a fusible interlining 1, each pant leg comprises a front panel 2 and a back panel 3, the fusible interlining 1 is being disposed on the back panel 3 and adhered to the bottom 11 and outside 12 of the hips 7; at the same time, a fusible interlining 1 is disposed on inside of front panel 2 and opposite to the fusible interlining 1 of the back panel 3; the fusible interlining 1 has an arc-shaped portion 4, and the arc-shaped portion 4 is recessed downwards. The structure of the fusible interlining 1 designed by the invention is kept away from the positions of the hips 7, such that the hips areas 7 are in elastic fabric, and whole hips 7 will become more rounded. The fusible interlining is used to reduce the elasticity on all around and bottom 11 of hips 7. The outer edges of the fusible interlining 1 are aligned with the outer edges of the front panel 2 and the back panel 3. The length of fusible interlining 1 is the distance from the crotch point 6 extending downwards 2-15 cm to the outer edge of waistband 5. The length may help tighten up the shape from the hips 7 to the thighs.
Preferably, as shown in FIG. 1 and FIG. 2, one end of the arc-shaped portion 4 is located at the lower edge of the waistband 5, and another end is equal to or higher than the crotch 6. It is required for the location on the inner thigh where the fusible interlining 1 is disposed by ironing to be equal to or higher than the crotch 6, which may help to tightening up the fat on the inner thigh.
In a production process of pushup jeans, two pant legs of jeans are sewn by front panels 2 and back panels 3, and a fusible interlining 1 is adhered to bottom 11 and outside 12 of the hips on the back panel 3 by iron-pressing; and a fusible interlining 1 is disposed at a location within the front panel 2 and opposite to the fusible interlining 1 of the back panel 3. The process comprises the steps of:
a) cutting the fusible interlining 1, the shape of the fusible interlining 1 being equal to the shape on the sewing thread location of pant legs; as shown in the figures, since the fusible interlining 1 does not need to be stitched by thread, its outer edges need be aligned with the outer edges of the panel to avoid an uneven situation;
b) laying the fusible interlining 1 on the panel and aligning their outer edges with the panel;
c) turning the temperature of the iron-pressing machine to 140° C.-160° C., and setting a constant temperature after heating;
d) adjusting the pressure parameter of the iron-pressing machine to be 2-3.5 kg; since the tolerance of the jeans and the fusible interlining 1 are different, there is a strict control for the pressure, temperature and time to avoid damage of fusible interlining 1, wherein generally, the tolerable temperature of the jeans is 120° C. -160° C., the tolerable temperature of the fusible interlining 1 is 120° C.-160° C.; the tolerable pressure of the jeans is 2 kg-5 kg, that of the fusible interlining 1 is 2 kg-3.5 kg; if the temperature is to high, the fusible interlining will be melted, and damage the jeans, even if it can be adhered closely to the jeans, the structure will be disrupted and cannot reduce the elasticity of the fabric effectively; as for the tolerable pressure, in order that the adhered fusible interlining 1 is not too thick to affect patterns as appeared in washing process, the pressure of 2 kg-3.5 kg is constantly adopted;
e) putting the lain fusible interlining 1 with the panel into the iron-pressing machine for iron-pressing;
f) sewing the ironed front panel 2 or back panel 3 to form the pant leg.
Preferably, the iron-pressing machine is a roller-type pressing machine. A roller-type pressing machine can guarantee an evenly distributed stress and make the whole fusible interlining 1 adhered fully and closely.
Preferably, the iron-pressing time of the step e) is 10-17 seconds.
In the above steps, sewing is performed after iron-pressing, that front panel 2 and back panel 3 can be stitched with fusible interlining 1 at the same time. This can help to reduce the opening of the interlining at the stitched positions during long-term use.
The above description is not intended to make any limitation on the scope of the invention, and any amendments, equivalent variations and modifications made to the above embodiments according to the technical essence of the invention fall into the scope of the technical solutions of the invention.
