In order to achieve the above purpose, the present utility model provides the following technical solutions: the novel hot-melt spliced pillowcase comprises a pillowcase bottom fabric, wherein a pillowcase top fabric is arranged at the top of the pillowcase bottom fabric, and a spliced fabric is arranged at the center of the top of the pillowcase top fabric.
Preferably, the surface center position of the pillowcase bottom layer fabric relative to the pillowcase top layer fabric is provided with a reinforcing rib, and the inner bottom end of the spliced fabric is provided with a connecting fabric.
Preferably, a glue layer is arranged between the connecting fabric and the pillowcase top fabric, and hot melt strips for hot melt welding are arranged on the upper surfaces of the spliced fabrics.
Preferably, the bottom layer fabric and the top layer fabric of the pillowcase can be spandex or nylon.
Preferably, the reinforcing ribs are arranged in a plurality of groups, and are arranged between the bottom layer fabric and the top layer fabric of the pillowcase in an array manner, and the reinforcing ribs are elastic bands.
Preferably, the glue layer is an oily single-component polyurethane adhesive with the viscosity of 200Pa.s and is heat-set.
Compared with the prior art, the utility model has the beneficial effects that:
through being equipped with connecting fabric and concatenation surface fabric, with pillowcase bottom surface fabric, pillowcase top surface fabric, connect the surface fabric and splice the surface fabric all adopt the composition to contain the surface fabric of spandex and polyamide fibre, in ultrasonic welding process, the firm not good condition takes place, splice two sets of pillowcase bottom surface fabric and two sets of pillowcase top surface fabric each other simultaneously, the junction between pillowcase top surface fabric is adhered to the glue that will connect the surface fabric again, wait to connect the surface fabric adhesion and accomplish the back, place the concatenation surface fabric, at last by the ultrasonic wave with its hot melt welding after-mentioned fifty percent discount together, the trilateral also is so in addition, thereby form complete seamless pillowcase, effectually solved the problem of making the pillowcase easy invasion and the breeding of causing bacterium, dirt, also improved the safety in utilization of seamless pillowcase simultaneously.
Drawings
FIG. 1 is a schematic view of the overall structure provided by the present utility model;
FIG. 2 is a partially exploded view of the present utility model;
fig. 3 is a schematic structural diagram of a spliced fabric provided by the utility model.
In the figure: 1. a pillowcase bottom fabric; 2. a pillowcase top layer fabric; 3. reinforcing ribs; 4. connecting fabrics; 5. a glue layer; 6. splicing the fabric; 7. and (5) hot melting the strip.
Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
The utility model provides the following technical scheme: novel hot melt concatenation pillowcase can effectually solve the pillowcase and need not to make up the effect at the in-process of using, has increased connect surface fabric 4 and concatenation surface fabric 6, please refer to fig. 1-3, including pillowcase bottom surface fabric 1, pillowcase bottom surface fabric 1's top is provided with pillowcase top layer surface fabric 2, pillowcase bottom surface fabric 1 is provided with strengthening rib 3 relative pillowcase top layer surface fabric 2's surface central point put, pillowcase top layer surface fabric 2's top central point put and is provided with concatenation surface fabric 6, the inside bottom of concatenation surface fabric 6 is provided with connects surface fabric 4, be provided with glue layer 5 between connection surface fabric 4 and the pillowcase top layer surface fabric 2, the upper surface of concatenation surface fabric 6 all is provided with the hot melt strip 7 that is used for hot melt welding.
Working principle: when the utility model is used, the pillowcase bottom layer fabric 1, the pillowcase top layer fabric 2, the connecting fabric 4 and the spliced fabric 6 are all made of polyurethane blended fabric with components of ammonia nylon, 10-20% of polyurethane, 80-90% of nylon and 130-300g/m < 2 > in gram weight, so as to avoid poor firmness in the ultrasonic welding process, when welding, the two groups of pillowcase bottom layer fabrics 1 and the two groups of pillowcase top layer fabrics 2 are spliced with each other, a plurality of reinforcing ribs 3 are placed between the two groups of pillowcase bottom layer fabrics 1 and the two groups of pillowcase top layer fabrics 2, then the connecting fabric 4 is adhered to the joint between the pillowcase top layer fabrics 2 together with a glue layer 5, the glue layer 5 is selected from oily single-component polyurethane adhesive with the viscosity of 200Pa.s, and is sprayed between the connecting fabric and the pillowcase top layer fabrics 2 respectively, the bonding firmness amount of the two is about 20-80g/m < 2 >, a heavy object is needed to be flattened after the compounding is finished, and wrinkles are prevented, after standing for 5-8H, checking sheets, namely, defective materials and less material cutting sheets do not flow into the next procedure, after the connecting fabric 4 is adhered, placing the spliced fabric 6, finally sending the spliced fabric 6 between a vibrating ultrasonic amplitude transformer and a fixed anvil by ultrasonic waves, enabling high-frequency mechanical vibration to reach 20-40kHz, enabling thermoplastic parts to generate friction heat at an interface, thereby obtaining enough temperature to melt and bond the fabrics, carrying out hot-melt welding together, and then doubling back on the three sides, thereby forming a complete seamless pillowcase, effectively solving the problems that bacteria and dirt are easy to invade and breed in the pillowcase, improving the use safety of the seamless pillowcase, simultaneously attaching a thin layer of PUR adhesive tape on the welding back in order to prevent adverse phenomena of cracking, cotton burst and the like of the pillowcase after ultrasonic is finished in the subsequent water washing process, not only beautifies the splice but also enhances the firmness of the splice.
