Problems solved by technology

[0004] At present, the PVC composite fabrics for bags on the market generally use skeleton fabrics laminated with double-layer PVC films, and in order to enhance the peeling load between them, the skeleton fabrics need to be coated with squeegee before laminating PVC films, so this kind of products exist as follows Disadvantages: 1. The product lacks a three-dimensional sense, and it feels lacking in grade in appearance; 2. The air permeability effect is poor

Embodiment 1

[0070] like figure 1 As shown, the composite fabric for making the luggage includes the main body, and the main body is formed by laminating the PVC film 1 and the skeleton fabric layer 2 at a high temperature of 200°C. Wherein, the PVC film is prepared from the following raw materials in parts by weight: PVC resin 100; calcium carbonate 20; stabilizer 5; rutile titanium dioxide 3; plasticizer 45; soybean oil 2.5; The fabric of the skeleton fabric layer 2 is a polyester woven fabric with a fineness of 250D×250D and a density of 27×25 threads / inch.

[0071] To further illustrate, the thickness of the PVC film 1 is 18 filaments; the body is densely covered with through holes 22, the through holes 22 are straight holes and the extension direction of the axis is consistent with the distribution direction of the PVC film 1 and the skeleton fabric layer 2. In this embodiment, the diameter of the through hole 22 is preferably 0.6 mm. In the actual production of bags, a waterproof a...

Embodiment 2

[0104] The structure and principle of this embodiment two are basically the same as those of embodiment one, except that the PVC film is made of the following raw materials in parts by weight: PVC resin 100; calcium carbonate 25; stabilizer 5; rutile titanium dioxide 4; Plastic agent 45; soybean oil 2.5; color additive 2.75; the aperture of the through hole 22 is 1 mm.

[0105] The processing technology of the composite fabric for making bags includes a PVC film calendering process and a laminating process, and the PVC film calendering process is before the laminating process.

[0106] Wherein, the PVC film calendering process comprises the following steps:

[0107] A, metering: each raw material is weighed by weight;

[0108] B. Stirring and mixing: first pour the PVC resin into the mixer, then pour in the liquid raw materials, control the temperature at 105°C, stir at a speed of 350r / min, and stir for 180s; then pour in the powdery raw materials and control the temperature ...

Embodiment 3

[0122] The structure and principle of this embodiment three are basically the same as those of embodiment one, except that the PVC film is made of the following raw materials in parts by weight: PVC resin 100; calcium carbonate 30; stabilizer 5; rutile titanium dioxide 5; Plastic agent 45; soybean oil 2.5; color additive 3; the aperture of the through hole 22 is 1.8mm.

[0123] The processing technology of the composite fabric for making bags includes a PVC film calendering process and a laminating process, and the PVC film calendering process is before the laminating process.

[0124] Wherein, the PVC film calendering process comprises the following steps:

[0125] A, metering: each raw material is weighed by weight;

[0126] B. Stirring and mixing: first pour the PVC resin into the mixer, then pour in the liquid raw materials, control the temperature at 105°C, stir at a speed of 400r / min, and stir for 180s; then pour in the powdery raw materials and control the temperature ...

Abstract

The invention provides a composite fabric for making suitcases and bags and a processing technology of the composite fabric, and belongs to the field of light industry textiles. The invention solves the problem that an existing fabric has a poor ventilation effect. The composite fabric for making the suitcases and bags comprises a body formed by laminating a PVC film and a skeleton fabric layer, wherein the body is densely covered with through holes which are in the shape of straight holes, the extending directions of axes of the through holes are consistent with distribution directions of the PVC film and the skeleton fabric layer, and the pore size of the through holes is 0.6-1.8mm; the processing technology consists of a PVC film calendering process and a lamination process, wherein the PVC film calendering process comprises the steps of A, measurement, B, stirring mixing, C, internal mixing, D, continuous plasticization with two rolling wheels, E, filtration, F, four-roll calendering, G, sub-surface embossing, H, cooling shaping, and I, coiling; the lamination process comprises the following steps of: J, high-temperature lamination, K, cooling shaping and edge cutting, L, through hole forming, and M, furling. The composite fabric for making the suitcases and bag and the processing technology of the composite fabric have the advantage that the ventilation effect of the composite fabric can be improved.

Description

technical field [0001] The invention belongs to the field of light industry and textiles, and relates to a composite fabric, in particular to a composite fabric for making bags and a processing technology thereof. Background technique [0002] Luggage is a general term for bags, a general term for all kinds of bags used to hold things, including general shopping bags, backpacks, satchels and various trolley cases.
