Problems solved by technology

However, as the flatness of the fabric becomes higher and higher, the sewability of the garment is getting worse, and the flatness of the seam of the garment is also getting worse.
In order to improve the flatness of the seams, we use the method of adding moldings to the seams, and then heat-press the parts where the moldings are added. Although there is some improvement, it still does not meet the standards and customer requirements.
Moreover, the process of sewing and flat pressing is disconnected, non-continuous
Therefore, more operators are required to operate at the same time, which wastes manpower and material resources. At the same time, the effect of flatness is different, and it is impossible to ensure that the flatness can be kept consistent.

Embodiment 1

[0034] The present invention will be further described below in conjunction with accompanying drawing.

[0035] like Figure 1-2 As shown, a device for improving the seam flatness of non-ironing fabrics according to the present invention includes:

[0036] The upper molding mechanism 1 is used for unwinding and conveying the molding 10 used for non-ironing;

[0037] The guide 2 before sewing is arranged on the rear side of the upper molding mechanism 1, and is used to introduce the molding 10, the upper fabric 8 and the lower fabric 9 into the sewing area;

[0038] The sewing machine 3 is arranged on the rear side of the guide 2 before sewing, and is used to sew the molding 10, the upper fabric 8 and the lower fabric 9, and controls the forward speed of the sewn fabric through the needle speed;

[0039] The heating unit 5 is arranged on the rear side of the sewing machine 3, and is used for melting the molding 10 on the inside of the sewn fabric, and stretching and shaping t...

Embodiment 2

[0061] S3 conveys the preliminary fabric to the heating part 5 through the driving roller 4-2 of the pressing guide wheel 4 for pressurization and heating, and adjusts the transmission speed of the heating part 5. The transmission speed of the heating part 5 is the sewing speed of the sewing machine 3 1 times, the heating part 5 stretches and flattens the inner fillet 10 after melting;

[0062] S4 cools and presses the stretched and flattened fabric through the cooling part 6, and compresses and transmits it. The cooling part 6 adjusts its transmission speed. The transmission speed of the cooling part 6 is 1 times the transmission speed of the heating part 5. The cooling part 6 is used to Stretch and flatten the inner molding 10 after cooling.

[0063] The speed of the sewing machine 3 is 100mm / s in the step S2;

[0064] The heating temperature of the heating part 5 described in step S3 is 140°C, and the pressure of the heating part 5 on the sewing fabric is controlled at 25N...

Embodiment 3

[0068] S3 conveys the preliminary fabric to the heating part 5 through the driving roller 4-2 of the pressing guide wheel 4 for pressurization and heating, and adjusts the transmission speed of the heating part 5. The transmission speed of the heating part 5 is the sewing speed of the sewing machine 3 1.05 times of , the heating part 5 stretches and flattens the inner fillet 10 after melting;

[0069] S4 cools and presses the stretched and flattened fabric through the cooling part 6, and compresses and transmits it. The cooling part 6 adjusts its transmission speed. The transmission speed of the cooling part 6 is 1.05 times that of the heating part 5. The cooling part 6 is used to Stretch and flatten the inner molding 10 after cooling.

[0070] The speed of sewing machine 3 is 150mm / s in the step S2;

[0071] The heating temperature of the heating part 5 described in step S3 is 170°C, and the pressure of the heating part 5 on the sewing fabric is controlled at 50N;

Abstract

The invention relates to a device and method for improving seam smoothness of easy-care fabric and belongs to the technical field of textile. The invention solves the problems of poor smoothness and high processing difficulty of a seam of the existing fabric. The device comprises: an upper filler mechanism, which is used for uncoiling and conveying a filler for ease-care use; a pre-sewing guide arranged in the rear of the upper filler mechanism and used for guiding the filler, upper fabric and lower fabric into a sewing area; a sewing machine arranged in the rear of the pre-sewing guide and used for sewing the filler, the upper fabric and the lower fabric, and for controlling advancing speed of the sewed fabric according to a needle traveling speed; a heating part arranged in the rear of the sewing machine and used for melting the filler on the inner side of the sewed fabric and for drawing and setting a sewing seam; and a cooling part arranged in the rear of the heating part and usedfor cooling the heated and drawn fabric and solidifying and setting the filler.

Description

technical field [0001] The invention relates to a device and a method for improving the flatness of seams of non-ironing fabrics, belonging to the technical field of textiles. Background technique [0002] With the diversified needs of the market and the fast pace of life, people's requirements for clothing are also constantly increasing. High non-ironing and easy care have become the first choice of many people in the industry. But as the flatness of the fabric is getting higher and higher, the sewable performance of its ready-made garments is just getting worse, and the flatness of the seams of the clothes is also getting worse. In order to improve the flatness of the seam, we use the method of adding moldings to the seams, and then heat-press the parts where the moldings are added. Although there is some improvement, it still does not meet the standards and customer requirements. Moreover, the process of sewing and flat pressing is a disconnection operation, which is di...
