Abstract
The invention discloses a method for ultrasonically bonding double layer cutting piece of underwear, comprising the steps of: first of all, superposing at least two layers of cloth in parallel; then pressing downwardly a die orifice of a portable ultrasonic welding machine along the edge of the cloth, utilizing the ultrasonic emitted from the die orifice of the portable ultrasonic welding machine to weld the superposed cloth with the heat generated at a place where the ultrasonic contacts with the cloth. The invention applies the working principle of the ultrasonic to the superposition welding for the double layer materials during clothes production, such that the welding positions are free of being sewed by a sewing machine. After the products manufacturing comes to an end, the procedure-breaking a connection line by pulling is not added at the time of product checking; the invention can save labor and material costs and efficiently settle the flaw that the double layer materials in the current clothes production can only be jointed by the sewing machine even at high cost.
Description
Technical field
The present invention relates to the preparation method of underwear in the apparel industry, relate in particular to a kind of preparation method at two overlapping connections of cut-parts of garment production.
Background technology
Along with rapid economy development, people's living standard improves constantly, and the production cost of factory also improves relatively.Constantly perfecting of labour law brought new test also for the production efficiency of each big production plant.Connection between two overlapping cut-parts of existing underwear all is to adopt the superimposed connected mode of making of single needle (flatcar) sewing machine to make usually.For example, the width of cloth has surface layer and nexine double-layer cloth before the existing underpants, and its operating procedure is: at first with the overlapping concordant placement of surface layer and nexine at grade, use the single needle sewing machine that surface layer and nexine is superimposed then, and finish being connected of surface layer and nexine along side seam system; Again for example, during the cup position employing double-decker of chest measurement, the technology that is connected of surface layer cup position and nexine cup position is: earlier with surface layer cup position and the overlapping concordant placement in nexine cup position at grade, use the single needle sewing machine that surface layer cup position and nexine cup position is superimposed then, and finish being connected of surface layer cup position and nexine cup position along side seam system.
The overlapping connected mode of making of this tradition makes and the joint at the double-deck position of underwear all adopts the single needle sewing machine to engage, and the equipment cost height; Finish the suture that to break surface layer and nexine when looking into goods at the finished product of underwear, otherwise when wearing, strut, the sound that has fracture occurs, and the sound of this fracture can cause the problematic illusion of product quality, also can increase the cost and the cost of labor of wire rod in addition.
Summary of the invention
The objective of the invention is to solve above-mentioned technical problem, propose a kind of method of bonding double-layer slittings of underwear by ultrasonic.
Technical scheme of the present invention is the method that proposes a kind of bonding double-layer slittings of underwear by ultrasonic, and its step is as follows:
Step 1: will be at least two layers of cloth is concordant overlaps;
Step 2: the die orifice of the portable ultrasonic welding machine edge along described cloth is pressed down, utilize the ultrasonic wave that sends on this portable ultrasonic welding machine die orifice, the overlapping cloth of heat welding that produces in itself and cloth contact site.
The present invention can press down welding along described cloth marginating compartment with the die orifice of portable ultrasonic welding machine, also can press down welding along the continuous edge of described cloth.
Described cloth is any in the cloth of natural fiber textile cloth, staple fibre textile cloth, natural fiber and staple fibre blending.
The frequency of ultrasonic that described portable supersonic welding cutter produces is 20000 hertz to 28000 hertz.
The present invention is used for the overlapping welding of the double-deck material of garment production with hyperacoustic operation principle, makes welding position without stitching sewing machine.The more important thing is and adopt portable supersonic welding cutter, the size of its die orifice can be done lessly, thereby adopts process of the present invention, removes the linear edge that can weld cloth, can also weld the curved edge of cloth.After being made into product, need not add operation-break connecting line when looking into goods in addition, can also save cost of labor and wire rod cost, and solve the double-deck material of existing garment production effectively and can only engage and defect of high cost with sewing machine.
Description of drawings
Below in conjunction with the drawings and specific embodiments the present invention is done detailed explanation, wherein:
Fig. 1 is the schematic diagram of preferred embodiment processing step one of the present invention;
Fig. 2 is the schematic diagram of preferred embodiment processing step two of the present invention;
Fig. 3 is the schematic diagram after preferred embodiment of the present invention is finished.
The specific embodiment
Fig. 1, Fig. 2 show the technology that is connected that the width of cloth before preferred embodiment-underpants of the present invention has surface layer and nexine double-layer cloth, and the method that double-layer slittings of underwear by ultrasonic of the present invention bonds comprises the following steps:
Two layers of cloth 1 concordant overlaping with surface layer with the nexine of the width of cloth before the underpants.Open portable supersonic welding cutter 2, send ultrasonic wave.The die orifice 3 of the portable ultrasonic welding machine marginating compartment along double-layer cloth 1 is pressed down, utilize the ultrasonic wave that sends on this portable ultrasonic welding machine die orifice, the 4 overlapping clothes of heat welding that produce in itself and cloth contact site, thus two layers of cloth coupled together (as shown in Figure 3).
According to arts demand, the die orifice of portable ultrasonic welding machine can also be pressed down welding along the continuous edge of described cloth, promptly make the continuous edge of double-layer cloth bond, obtain higher bonding strength.Because the die orifice size of portable supersonic welding cutter can be done lessly, thereby adopts process of the present invention, remove the linear edge that can weld cloth, can also weld the curved edge of cloth, this is that the present invention is different from one of emphasis of prior art.Certainly can also utilize this portable ultrasonic welding machine two-layer above cloth that bonds.
According to the size that is connected material size (thickness, width) and material (can make) by in the cloth of natural fiber textile cloth, staple fibre textile cloth, natural fiber and staple fibre blending any, control the pressure of portable supersonic welding cutter die orifice 3 and the time that stop is cut in weldering, usually the pressure that adopts is: 1 to 4 kgf, sending frequency by the supersonic welding cutter is that the ultrasonic wave of 20000 hertz or 28000 hertz produces heat.Pressure is big more, and the time is of a specified duration more, and the heat of generation is just many more.
The connected structure that adopts technology of the present invention to make comes down to the structure of " welding ", is different from the structure of traditional handicraft " sewing " fully.This novel welding procedure makes the joint method diversification more of textile underwear, after being made into product, need not add operation-break connecting line when looking into goods in addition, can also save cost of labor and wire rod cost, and solve the double-deck material of existing garment production effectively and can only engage and the high technical problem of cost with sewing machine.
