Description

Technical Field

[0001] The present application relates to the field of textile technology, and in particular to an engraved roller structure for fabric pressing and a composite fabric pressing device. Background Art

[0002] In the textile field, composite fabrics are made by bonding one or more layers of textile materials, non-woven materials and other functional materials together to form a fabric with multiple properties. Composite fabrics can be used for daily wear, especially in outdoor sportswear. The composite process is a key link in the preparation of composite fabrics. At present, the research on the composite process is basically from the aspects of adhesives, bonding temperature, and aging time. However, the bonding strength of composite fabrics prepared by the current composite process needs to be improved, and the composite fabrics are not soft and have average breathability. Utility Model Content

[0003] Based on this, it is necessary to provide a carved roller structure for fabric lamination. The carved roller structure for fabric lamination of the utility model can be used in the production and preparation process of composite fabrics. The prepared composite fabric has high bonding strength and can improve the soft feel and air permeability of the composite fabric.

[0004] An embodiment of the present application provides a carved roller structure for fabric lamination.

[0005] A carving roller structure for fabric lamination comprises a carving roller having a rolling surface, a plurality of adhesive accommodating grooves are arranged on the rolling surface according to a topological structure.

[0006] In some embodiments, the engraving roller is in a cylindrical structure, and the outer peripheral surface of the engraving roller forms the rolling surface.

[0007] In some of the embodiments, the glue accommodating groove is a hemispherical groove.

[0008] In some embodiments, the inner diameter d1 of the glue accommodating groove is 0.1 mm to 3 mm.

[0009] In some embodiments, the depth of the glue accommodating groove is 0.1 mm to 2 mm.

[0010] In some embodiments, a plurality of the glue accommodating grooves are distributed in a group along the axial direction of the engraving roller, and a plurality of groups are distributed at intervals on the engraving roller, wherein the glue accommodating grooves between adjacent groups are staggered.

[0011] In some of the embodiments, the distance d2 between two adjacent adhesive accommodating grooves in each group is 0.5 mm to 3 mm.

[0017] The above-mentioned engraved roller structure for fabric pressing can be used in the production and preparation process of composite fabrics. The prepared composite fabric has high bonding strength and can improve the soft feel of the composite fabric and the breathability of the composite fabric. The shape of the glue groove of the traditional engraved roller is rhombus or circular. The arrangement rule of the rhombus points has the same spacing between the points and the relatively good water pressure resistance, but the prepared composite fabric feels hard, which affects the wearing comfort. The glue points obtained by the dot-shaped glue groove are generally arranged irregularly. Compared with the rhombus glue groove, this arrangement method makes the composite fabric feel soft, but the water pressure resistance is relatively weak. Compared with the traditional technology, the present application adopts the arrangement rule of the topological structure of the glue groove.

[0029] The embodiment of the present application provides an engraved roller structure for fabric lamination to solve the problems that the bonding strength of the composite fabric prepared by the composite process in the conventional technology needs to be improved, the composite fabric has a poor soft feel, and the fabric has average air permeability. The engraved roller structure for fabric lamination will be described below in conjunction with the accompanying drawings.

[0030] The engraved roller structure for fabric lamination provided in the embodiment of the present application is exemplary, see Figure 1 As shown, Figure 1 This is a schematic diagram of a partial rolling surface structure of an engraved roller body for fabric lamination provided in an embodiment of the present application. The engraved roller body structure for fabric lamination of the present application can be used for lamination and bonding of composite fabrics.

[0031] In order to more clearly illustrate the structure of the engraved roller body structure for fabric pressing, the engraved roller body structure for fabric pressing will be introduced below in conjunction with the accompanying drawings.

[0032] For example, see Figure 1 As shown, a carved roller structure for fabric lamination includes a carved roller. The carved roller has a rolling surface 10. A plurality of adhesive grooves 100 are arranged on the rolling surface 10. The plurality of adhesive grooves 100 are arranged and distributed on the rolling surface 10 according to a topological structure 200. It should be noted that Figure 1 Only a partial structure of the rolling surface 10 is shown.

[0033] The shape of the glue groove of the traditional engraving roller is diamond or circular. The regular arrangement of the diamond points has the same spacing between the points, and the water pressure resistance is relatively good, but the prepared composite fabric feels hard, which affects the wearing comfort. The glue points obtained from the dot-shaped glue groove are generally arranged irregularly. Compared with the diamond-shaped glue groove, this arrangement method makes the composite fabric feel soft, but the water pressure resistance is relatively weak. Compared with the traditional technology, the present application adopts the regular arrangement of the containing glue grooves 100 of the topological structure 200. The glue points obtained by the regular arrangement of the containing glue grooves 100 of the topological structure 200 can have the characteristics of low glue point density, large space and high strength, which can improve the bonding strength of the composite fabric, and the prepared composite fabric feels soft and has good breathability. After many experiments and verifications, the present application adopts multiple containing glue grooves 100 with a regular arrangement of the topological structure 200, which can improve the soft feel of the composite fabric.

[0034] In some embodiments, the engraving roller is cylindrical. The outer circumference of the engraving roller forms a rolling surface 10. In the process of processing the composite fabric, the adhesive is first applied to the outer circumference of the engraving roller, that is, the rolling surface 10, so that each adhesive groove 100 is evenly filled with adhesive, and then the excess adhesive on the rolling surface 10 is scraped off manually or by machine, and the rolling surface 10 of the engraving roller is controlled to contact with one of the layers of fabric to be bonded, and the adhesive in the adhesive groove 100 on the rolling surface 10 of the engraving roller is transferred to the fabric, and then the rolling surface 10 of the engraving roller is controlled to contact with another layer of fabric to be bonded, and the adhesive in the adhesive groove 100 on the rolling surface 10 of the engraving roller is transferred to the fabric, and after removing the engraving roller, the two layers of fabric coated with adhesive are bonded together by adhesive, and then after hot pressing and shaping, a composite fabric is obtained. It should be noted that the composite fabric can be a composite of two layers of fabric, or a composite of three layers of fabric or four layers of fabric. The number of fabric layers of the composite fabric can be set according to actual needs. The adhesive coating of each layer of fabric can be carried out according to the above steps.

[0035] In some embodiments, the adhesive receiving groove 100 is a hemispherical groove, which means that the cross section of the adhesive receiving groove 100 is circular, and the adhesive receiving groove 100 is a concave hemispherical groove structure as a whole.

[0036] For some of these examples, see Figure 1 As shown, when the adhesive groove 100 is a hemispherical groove, the inner diameter (ball diameter) d1 of the adhesive groove 100 is 0.1 mm to 3 mm. For example, in a specific embodiment, the inner diameter of the adhesive groove 100 includes 0.1 mm, 0.5 mm, 1 mm, 2 mm, 3 mm or other values ​​and the range between any two of the above values.

[0037] In some embodiments, the depth (ball radius) of the adhesive groove 100 is 0.1 mm to 2 mm. For example, in a specific embodiment, the depth of the adhesive groove 100 includes 0.1 mm, 0.5 mm, 1 mm, 2 mm or other values ​​and the range between any two of the above values.

[0038] In some of the embodiments, a plurality of glue accommodating grooves 100 are distributed in a group along the axial direction of the engraving roller, and a plurality of groups are distributed at intervals on the engraving roller, wherein the glue accommodating grooves 100 between adjacent groups are staggered.

[0039] In some of these embodiments, see Figure 1 As shown, the distance of the staggered distribution of the adhesive containing grooves 100 between adjacent groups may be half of the distance d2 between two adjacent adhesive containing grooves 100 .

[0040] For some of these examples, see Figure 1 As shown, the spacing d2 between two adjacent adhesive grooves 100 in each group is 0.5 mm to 3 mm. For example, in a specific embodiment, the spacing between two adjacent adhesive grooves 100 in each group includes 0.1 mm, 0.5 mm, 1 mm, 2 mm, 3 mm or other values ​​and the range between any two of the above values. Preferably, the spacing d2 between two adjacent adhesive grooves 100 in each group is 0.5 mm to 1.5 mm.

[0041] For some of these examples, see Figure 1 As shown, the group spacing d3 between adjacent groups is 0.5 mm to 3 mm. For example, in a specific embodiment, the group spacing between adjacent groups includes 0.1 mm, 0.5 mm, 1 mm, 2 mm, 3 mm or other values ​​and a range between any two of the above values. Preferably, the group spacing d3 between adjacent groups is 0.5 mm to 1.5 mm.

[0042] For some of these examples, see Figure 1 As shown, in two adjacent groups, any four adhesive receiving grooves 100 form a parallelogram structure.

[0043] For some of these examples, see Figure 1 As shown, in any three adjacent groups, the six adjacent glue accommodating grooves 100 surrounding any one glue accommodating groove 100 in the middle group form a hexagonal structure.

[0044] Preferably, in one of the embodiments, in any three adjacent groups, the six adjacent glue accommodating grooves 100 surrounding any one glue accommodating groove 100 in the middle group form a regular hexagonal structure.

[0045] In the present application, the engraved roller structure used for fabric pressing is used in the process of preparing composite fabrics. The amount of glue applied on the fabric determines the bonding firmness of the composite fabric. However, too much glue will not only affect the feel of the composite fabric but also the air permeability of the composite fabric. The factors affecting the amount of glue applied include the density arrangement of the points and the diameter and depth of the points. The density refers to the number of the adhesive grooves 100 of the points within a unit area. The diameter of the adhesive grooves 100 determines the contact area between the hot melt adhesive and the fabric. The longer the diameter of the adhesive grooves 100, the larger the contact area, the stronger the bonding strength, but the composite fabric will also feel harder and harder. The depth and area of ​​the adhesive grooves 100 determine the amount of glue applied to each glue point. The larger the volume of the glue point, the more glue, the higher the bonding strength, but the fabric feels harder and the moisture permeability decreases more; less glue results in lower bonding strength of the composite fabric, softer fabric feel, and less moisture permeability decrease. Therefore, in the present application, by controlling the above parameters and controlling the glue coating coverage to about 25% to 30%, the composite fabric can have both bonding strength, soft feel and good comfort performance.

[0046] An embodiment of the present application also provides a composite fabric lamination device.

[0047] A composite fabric pressing device comprises a heat press and the above-mentioned engraved roller structure for fabric pressing. The engraved roller structure for fabric pressing is installed in the heat press.

The plurality of rubber accommodating grooves 100 are arranged and distributed on the rolling surface 10 according to a topological structure 200. The inner diameter d1 of the rubber accommodating groove 100 is 0.5 mm. The depth of the rubber accommodating groove 100 is 0.25 mm. The plurality of rubber accommodating grooves 100 are distributed in a group along the axial direction of the carved roller, and a plurality of groups are distributed at intervals on the carved roller, wherein the rubber accommodating grooves 100 between adjacent groups are staggered. In any two adjacent groups, any four rubber accommodating grooves 100 form a parallelogram structure. In any three adjacent groups, the six adjacent rubber accommodating grooves 100 around any one rubber accommodating groove 100 in the middle group form a regular hexagonal structure.
