INVENTION EMBODIMENTS

Implementation Method of the Invention

[0022] To further explain the adopted technical means and efficacy to achieve the intended purpose of the invention, the detailed description of the specific implementation method, structure, features and efficacy according to the invention is as follows, combined with the attached figures and preferred embodiments.

[0023] In the invention, the extrusion port of the PVC extender is the front side and the feed port of the extruder is the rear side.

Embodiment 1

[0024] As shown in FIG. 1-3, the three-layer core-spun webbing of the invention comprises the woven layer 1 and the inner core 2, wherein the woven layer 1 is wrapped outside the inner core 2, which comprises the filling layer 21 and the interlayer 22, wherein the filling layer 21 is filled inside the interlayer 22, and the outer surface of the interlayer 22 contacts the inner surface of the woven layer 1.

[0025] The interlayer 22 of the invention is made of plastic, specifically, a PVC hollow circular pipe, and the filling layer 21 is polyester or polypropylene filament and yarn. The PVC hollow circular pipe is produced and the filling layer 21 is filled into the interlayer 22 in the following way:

[0026] As shown in FIG. 1, the inner core 2, the yarn holder of the filaments and yarns used for the filling layer 21, is placed at the rear side of the inlet of the PVC extruder, the filaments and yarns of polyester or polypropylene pass through the central hole of the extrusion die of the extender, and the molten PVC is extruded through the extrusion die, thus forming a circular strip-shaped object with PVC hollow circular pipe outside and filaments and yarns of polyester or polypropylene filled inside. The filling layer 21 is in a bundle shape in the interlayer 22, that is, one filament and yarn of polyester or polypropylene are arranged in parallel along the length direction of the hollow circular pipe. PVC hollow round pipe has the waterproof, mildew-proof and oil-proof effects, which enhance the tensile breaking strength of the inner core 2 to make the interlayer 22 more expandable, stereoscopic, soft and elastic. The filling layer 21 can be filled during the processing of the interlayer 22, and the residual heat of the interlayer 22 and the incompletely cured PVC inside it can stick the filling layer 21 to prevent the filling layer 21 from separating from the interlayer 22.

[0027] It is further explained that the filling layer 21 can be directly filled with soft ropes or other materials.

[0028] It is further explained that the warps and wefts of the woven layer 1 are made of yarns or filaments of polyester or acrylic or polypropylene or nylon, and the warps, wefts and inner core 2 are crossed and arranged on a circular knitting machine or a webbing weaving machine as required to weave into a three-layer core-spun webbing.

[0029] Specifically, in the production process of the interlayer 22, the PVC extrusion temperature falls in the range of 120-170° C., and the temperature of the PVC extruder should be lowered, preferably 120-140° C., enabling the outer surface of the PVC hollow circular pipe to form a rough hair surface. The friction between the interlayer 22 and the woven layer 1 is increased to increase the cohesion fastness between the two layers; thereby, the interlayer 22 is not easy to be pulled out from the woven layer 1.

[0030] Further, the outer surface of the PVC hollow circular pipe can be directly processed to be smooth.

[0031] Further, the size of the cavity in the interlayer 22 determines the amount of filaments and yarns filling the layer 21.

[0032] A seat, including sofa, chair, hanging chair, lounge chair, stool, bench, dining chair, booth, footstool and chair cushion, is formed by winding the above-mentioned webbing around the framework of the seat, and the aforesaid webbing can also be used to make side tables, coffee tables and dining tables. The winding surface formed by the webbing is stiff and full, stereoscopic, waterproof, oil-proof and mildew-proof, and portable.

[0033] The invention relates to a three-layer core-spun webbing and a seat containing the webbing, which comprises a woven layer 1 and an inner core 2, wherein the woven layer 1 is wrapped outside the inner core 2, which comprises a filling layer 21 and an interlayer 22. The interlayer 22 is a hollow circular pipe, and the filling layer 21 is filled in the interlayer 22. The webbing is made into the planes of the table and the seat. The infilling 22 enhances the expansion degree, tensile breaking strength and elasticity of the inner core 2. The interlayer 22 is made of PVC material with good waterproof, mildew-proof and oil-proof effect, which only makes the woven layer wet after the webbing is exposed to rain water, and the webbing is easily dried due to outdoor wind and sun exposure or rapid indoor air circulation, thus preventing the webbing from mildewing and further prolonging the service life of the webbing. It is suitable for furniture and outdoor products such as tables, chairs, floor mats and carpets.

Embodiment 2

[0034] In this embodiment, in addition to the above materials, several thermal fuses are added to the warps and wefts of the woven layer 1, and the thermal fuses account for 2%-91% of the total fiber of the webbing. The thermal fuses can be nylon thermal fuses or polyester thermal fuses, which are evenly interwoven at the inner and outer sides of the woven layer 1. The woven webbing undergoes waterproof treatment, which adopts soaking and drying process. In the process, firstly, the webbing is immersed in waterproof agent and then dried to remove excess water, with the drying temperature being preferably 80-130° C., and the webbing is then baked at high temperature, preferably 140-180° C. Immersing the webbing into the waterproof agent makes the waterproof agent evenly distributed on the surface of the webbing, and the dried waterproof agent is attached to the surface of the webbing to form a waterproof film on the surface of the webbing via high-temperature baking. In this way, the surface of the webbing has good waterproof property. In the process of high-temperature baking, the thermal fuses melt, and for the outer side of the woven layer 1, both the yarns or filaments of the warps and wefts of the inner side of the woven layer 1, are adhered together by the thermal fuses to overcome the deformation commonly existing in the current webbing, making the shape and knitting tightness of the woven layer 1 always maintain the initial state. For the outer side of the woven layer 1, the woven layer 1 and the inner core 2 can be adhered to fix the relative position between the woven layer 1 and the inner core 2, thereby further enhancing the fastness of the woven layer 1 and the inner core 2.

[0035] What has been described above is only the preferred embodiment of the invention, and it does not limit the invention in any form. Although the invention has been disclosed as the preferred embodiment, it is not used to limit the invention. Any technician in the art may make some changes or modification with equivalent changes to generate equivalent embodiments by using the disclosed technical contents without departing from the scope of the technical solution of the invention. However, any simple modification, equivalent change or modification made to the above embodiment in line with the technical substance of the invention without deviating from the content of the technical solution of the invention shall still fall within the scope of the technical solution of the invention.

INDUSTRIAL PRACTICABILITY

[0036] The invention provides a three-layer core-spun webbing and a seat comprising the webbing, wherein the webbing comprises a woven layer 1 and an inner core 2. The woven layer 1 is wrapped outside the inner core 2, and the inner core 2 comprises a filling layer 21 and an interlayer 22, which is a hollow circular pipe, and the filling layer 21 is filled inside the interlayer 22. The webbing is made into the planes of the table and the seat. The infilling 22 enhances the expansion degree, tensile breaking strength and elasticity of the inner core 2. The interlayer 22 is made of PVC material with good waterproof, mildew-proof and oil-proof effects, which only causes the woven layer to be wet after the webbing is exposed to rain water, and makes the webbing very easy to dry due to outdoor wind and sun exposure or rapid indoor air circulation, thus preventing the webbing from mildewing and further prolonging the service life of the webbing. It is suitable for furniture and outdoor products such as tables, chairs, floor mats and carpets, and can be manufactured or used industrially, having industrial practicability.
