Quilting cushion and quilting cushion preparation methodTechnical field
The present invention relates to a kind of cushion, more particularly to quilting cushion and quilting cushion preparation method.
Background technology
At present, cushion industry, especially mattress industry, extensive utilization looped fabric add the mode of sponge to produce external casing of mattress,But because sponge main component is polyurethane and polyethers, oxidizable jaundice and discharge harmful toxic matter.3D warp-knitted spacers in recent yearsThe cushion industry that appears as of fabric brings environment-protecting asepsis, ventilative washable cushion.But due to the centre of 3D warp-knitted spacer fabricsLayer is supported by polyester monofilament, and monofilament has very strong rigidity, and when traditional needle is sewed to cushion, eedle is prickedStopped by monofilament during polyester monofilament or when eedle is moved, all easily cause eedle to fracture damage, in turn resulting in normally to give birth toProduce.So general in industry bonded looped fabric with 3D space fabrics using glue, but the feature of environmental protection of glue turns into againNew problem.
The content of the invention
Present invention solves the technical problem that being to provide a kind of asepsis environment-protecting, producing efficiency quilting cushion high.
The technical solution adopted for the present invention to solve the technical problems is：Quilting cushion, including 3D warp-knitted spacer fabrics layer,It is characterized in that：The 3D warp-knitted spacer fabrics layer melts the viscous precoat set with its surface by ultrosonic high-temp integrally to be tiedStructure.
It is further：The precoat that the surface is set includes upper strata fabric and lower floor's fabric, the 3D warp-knitted spacersFabric is arranged between upper strata fabric and lower floor's fabric.
The invention also discloses quilting cushion preparation method, including supersonic generator, supersonic generator top is setThere is cylinder shape metal die so that the passage for placing cushion is formed between supersonic generator and cylinder shape metal die；
During making, step is：
A, 3D warp-knitted spacer fabrics and fabric are overlapped to form into cushion, cushion is put into supersonic generator and cylinder shape goldBetween category mould；
B, by cylinder shape mould along cushion roll, due to each shell fabric of cushion under ul-trasonic irradiation frictional heat, andPressing is melted and is sticked together in the presence of cylinder shape metal die.
It is further：The depth of the cylinder shape metal die is 5mm-20mm.
The beneficial effects of the invention are as follows：Quilting cushion of the invention is using the 3D warp-knitted spacer fabrics of terylene material as centreLayer packing material, it melts and sticks together instead of tradition to make precoat that 3D warp-knitted spacer fabrics and its surface set by ultrasonic waveNeedlework sewing and glue bonding so that the quilting cushion for producing have it is three-dimensional it is attractive in appearance, do not break, without glue, environment-protecting asepsisThe features such as.

Specific embodiment
The present invention is further described with reference to the accompanying drawings and detailed description.
Quilting cushion as shown in Figures 1 to 4, including 3D warp-knitted spacer fabrics layer, the 3D warp-knitted spacer fabrics layer are logicalCross ultrosonic high-temp and melt viscous into a single integrated structure with its surface is set precoat；This quilting cushion is sewed without using needlework,Without using glue bonding so that the quilting cushion has three-dimensional attractive in appearance, does not break, without glue, the features such as environment-protecting asepsis, and shouldUsing the 3D warp-knitted spacer fabrics of terylene material as intermediate layer packing material in the middle of quilting cushion, it is ensured that cushion it is environmentally friendly, easyproThe features such as suitable, ventilative, easy cleaning, while using ultrasonic bonds so that quilting cushion is sewed without a pin pin, accelerates quiltingThe manufacture efficiency of cushion.
Additionally, the precoat that the surface is set includes upper strata fabric and lower floor's fabric, the 3D warp-knitted spacer fabrics setPut between upper strata fabric and lower floor's fabric, the upper strata fabric and lower floor's fabric are the knitting fabric of terylene material, it is ensured thatThe pliability of cushion.
The invention also discloses quilting cushion preparation method, including supersonic generator 4, the top of supersonic generator 4 setsIt is equipped with cylinder shape metal die 5 so that the passage for placing cushion is formed between supersonic generator 4 and cylinder shape metal die；
During making, step is：
A, 3D warp-knitted spacer fabrics and fabric are overlapped to form into cushion, cushion is put into supersonic generator (4) and rollerBetween shape metal die 5；
B, by cylinder shape mould along cushion roll, due to each shell fabric of cushion under ul-trasonic irradiation frictional heat, andPressing is melted and is sticked together in the presence of cylinder shape metal die 5.
The depth of the cylinder shape metal die 5 is 5mm-20mm.
Frictional heat is vibrated under ul-trasonic irradiation by each shell fabric in the presence of ultrasonic wave when using, is gradually melted,After now cylinder shape metal die 5 is rolled across, the protuberance of cylinder shape metal die 5 causes that three shell fabrics melt viscous to the pressure of cushionTogether, this method without foreign material so that the quilting cushion environment-protecting asepsis for producing, and adds when quilting cushion is manufacturedWork efficiency high, meanwhile, the surface of cylinder shape metal die 5 can be set to various decorative patterns so that whole quilting cushion shows metalThe decorative pattern of mould keeps the globality of trilaminate material simultaneously.
Particular embodiments described above, has been carried out further in detail to the purpose of the present invention, technical scheme and beneficial effectDescribe in detail bright, should be understood that and the foregoing is only specific embodiment of the invention, be not intended to limit the invention, it is allWithin the spirit and principles in the present invention, any modification, equivalent substitution and improvements done etc., should be included in guarantor of the inventionWithin the scope of shield.
