Description

Technical Field

[0001] This utility model relates to the field of fabrics, and in particular to a composite knitted fabric and its composite equipment. Background Technology

[0002] Common knitted fabrics include wool fiber knitted fabrics and synthetic fiber knitted fabrics. Wool knitted fabric is a representative of wool fiber knitted fabrics. This type of fabric has advantages such as good elasticity, strong moisture absorption, and good warmth retention.

[0003] Nylon, spandex and other knitted fabrics are representative of synthetic fiber knitted fabrics. These fabrics are characterized by good abrasion resistance, good elasticity and skin-friendliness.

[0004] However, chemical fiber fabrics have poor moisture absorption, and wool fibers, due to their fiber end shape and surface scale layer, can cause a slight prickling sensation during wear. How to integrate the advantages of the two fabrics and create a composite fabric that is both skin-friendly and moisture-absorbing is a problem that urgently needs to be solved in this field. Utility Model Content

[0005] The purpose of this invention is to provide a composite knitted fabric that is both skin-friendly and moisture-wicking; the purpose of this invention is also to provide a composite equipment for making the composite fabric.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model for a composite knitted fabric is as follows:

[0007] A composite knitted fabric includes an outer wool fiber knitted fabric and an inner synthetic fiber knitted fabric, and further includes an adhesive layer disposed between the outer wool fiber knitted fabric and the inner synthetic fiber knitted fabric. The outer wool fiber knitted fabric is bonded and fixed to the surface of the inner synthetic fiber knitted fabric by the adhesive layer. The adhesive layer is a water-permeable adhesive layer, or the adhesive layer has water-permeable holes distributed on it.

[0008] Furthermore, the outer layer of knitted fabric is made of wool fibers.

[0009] Furthermore, the inner synthetic fiber knitted fabric is either nylon fiber knitted fabric or spandex fiber knitted fabric.

[0010] Furthermore, the adhesive layer has water-permeable holes distributed evenly on it.

[0011] Furthermore, the adhesive layer includes multiple horizontal adhesive strips arranged in parallel and multiple vertical adhesive strips arranged in parallel, with each horizontal adhesive strip intersecting with the corresponding vertical adhesive strip, and the water-permeable hole being formed between two adjacent horizontal adhesive strips and two adjacent vertical adhesive strips.

[0012] Furthermore, the permeable holes are diamond-shaped.

[0013] The technical solution of the composite equipment in this utility model is as follows:

[0014] A composite device includes an outer layer wool fiber knitted fabric unwinding roller and an inner layer synthetic fiber knitted fabric unwinding roller, and also includes an adhesive coating table. An adhesive coating roller for applying adhesive to the upper surface of the inner layer synthetic fiber knitted fabric is disposed on the upper side of the adhesive coating table downstream of the inner layer synthetic fiber knitted fabric unwinding roller. The composite device also includes an extrusion roller disposed downstream of the adhesive coating roller for extruding the outer layer wool fiber knitted fabric and the inner layer synthetic fiber knitted fabric, and a composite knitted fabric take-up roller disposed downstream of the extrusion roller.

[0015] Furthermore, the outer periphery of the coating roller is provided with coating ridges, which include multiple parallel transverse ridges and multiple parallel longitudinal ridges, with each transverse ridge intersecting with the corresponding longitudinal ridge.

[0016] Furthermore, a rhomboid hole is formed between two adjacent transverse ribs and two adjacent longitudinal ribs.

[0017] Furthermore, a glue-applying brush for applying glue to the transverse and longitudinal ribs is provided on the right side of the glue-applying roller.

[0018] The beneficial effects of this utility model are as follows: In this utility model, the outer layer of wool fiber knitted fabric is bonded and fixed to the surface of the inner layer of synthetic fiber knitted fabric through an adhesive layer, thereby creating a brand-new composite knitted fabric. The adhesive layer is a water-permeable adhesive layer, or the adhesive layer has water-permeable holes. In this way, the inner synthetic fiber knitted fabric can ensure the skin-friendliness of the composite knitted fabric, while the outer layer of wool fiber knitted fabric has water absorption. When the user sweats, under the water absorption characteristics of the outer layer of wool fiber knitted fabric, the sweat can pass through the adhesive layer to the outer layer of wool fiber knitted fabric, forming a one-way moisture wicking effect and improving the moisture absorption and perspiration wicking properties of the composite fabric.

Detailed Implementation

[0025] To facilitate understanding of this utility model, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. The accompanying drawings show preferred embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0026] It should be noted that, unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention.

[0027] An embodiment of this utility model of a wool composite knitted fabric is shown below. Figures 1-4 As shown:

[0028] It includes an outer layer of wool fiber knitted fabric 4 and an inner layer of synthetic fiber knitted fabric 2, and also includes an adhesive layer 1 disposed between the outer layer of wool fiber knitted fabric 4 and the inner layer of synthetic fiber knitted fabric 4. The outer layer of wool fiber knitted fabric 4 is bonded and fixed to the outer surface of the inner layer of synthetic fiber knitted fabric 2 by the adhesive layer 1, and the adhesive layer has water-permeable holes 3 distributed on it.

[0029] In this embodiment, the outer wool fiber knitted fabric 4 is a wool fiber knitted fabric; the inner synthetic fiber knitted fabric 2 is a nylon fiber knitted fabric or a spandex fiber knitted fabric.

[0030] The permeable holes are evenly distributed on the adhesive layer. Specifically, the adhesive layer includes a plurality of horizontal adhesive strips 5 arranged in parallel and a plurality of vertical adhesive strips 6 arranged in parallel. Each horizontal adhesive strip 5 is intersected with the corresponding vertical adhesive strip 6, and the permeable holes 3 are formed between two adjacent horizontal adhesive strips 5 and two adjacent vertical adhesive strips 6.

[0031] In other embodiments of this utility model, the water-permeable hole 3 may be omitted. In this case, the adhesive layer 1 can be uniformly coated between the outer wool fiber knitted fabric and the inner synthetic fiber knitted fabric. At this time, the adhesive layer 1 needs to be a water-permeable adhesive layer, for example, the adhesive layer is an epoxy resin adhesive layer, and the epoxy resin has a certain water permeability after curing.

[0032] An example of a laminating device for wool composite knitted fabrics Figures 1-4 As shown:

[0033] It includes an outer layer wool fiber knitted fabric unwinding roller 8 and an inner layer synthetic fiber knitted fabric unwinding roller 7. In use, the outer layer wool fiber knitted fabric 4 is wound onto the outer layer wool fiber knitted fabric unwinding roller 8, and the outer layer wool fiber knitted fabric unwinding roller is rotated to unwind; the inner layer synthetic fiber knitted fabric 2 is wound onto the inner layer synthetic fiber knitted fabric unwinding roller 7, and the inner layer synthetic fiber knitted fabric unwinding roller is rotated to unwind the inner synthetic fiber knitted fabric.

[0034] The laminating equipment also includes a coating worktable 10, on the upper side of the coating worktable 10 downstream of the inner synthetic fiber knitted fabric unwinding roller, a coating roller 9 for coating the upper surface of the inner synthetic fiber knitted fabric with adhesive. The laminating equipment also includes a compression roller 13 downstream of the coating roller for extruding the outer wool fiber knitted fabric and the inner synthetic fiber knitted fabric. The laminating equipment also includes a composite knitted fabric take-up roller 14 downstream of the compression roller.

[0035] The outer periphery of the coating roller is provided with coating ridges, which include multiple parallel transverse ridges 16 and multiple parallel longitudinal ridges 17. Each transverse ridge 16 intersects with the corresponding longitudinal ridge 17. A diamond-shaped hole 18 is formed between two adjacent transverse ridges 16 and two adjacent longitudinal ridges 17.

[0036] The right side of the coating roller 9 is provided with a coating brush 11 for applying adhesive to the transverse ribs 16 and the longitudinal ribs 17. Adhesive can be added to the coating brush 11 manually or by using a metering glue dispenser. The glue replenishment on the coating brush is prior art and will not be described in detail here.

[0037] In use, the composite knitted fabric take-up roller is an active roller driven by a motor. As the composite knitted fabric take-up roller rotates, the outer wool fiber knitted fabric unwinding roller and the inner wool fiber knitted fabric unwinding roller follow suit. The glue coating roller is an active roller driven by a power mechanism. During the rotation of the glue coating roller, the glue brush applies glue to the transverse and longitudinal ribs. Then, the glue coating roller applies the glue on the transverse and longitudinal ribs to the upper surface of the inner synthetic fiber knitted fabric. Then, the outer wool fiber knitted fabric and the inner synthetic fiber knitted fabric adhere to each other. The extrusion roller is used to squeeze the outer wool fiber knitted fabric and the inner synthetic fiber knitted fabric tightly to form a composite knitted fabric, which is finally taken up by the composite knitted fabric take-up roller.

[0038] In this invention, the inner layer of synthetic fiber knitted fabric enhances the fabric's skin-friendliness; the inner layer wicks away sweat quickly, while the outer layer absorbs moisture rapidly, creating a one-way moisture-wicking effect and improving the fabric's moisture absorption and wicking properties; it also improves the shape retention of the wool fabric, enhancing the elastic recovery of the wool after the composite process, resulting in higher fabric stability; and it improves the fabric's crispness, as thin wool is generally quite soft and limp, while the composite fabric becomes crisper, resulting in a better overall shape when made into clothing. The inner layer of synthetic fiber knitted fabric is a nylon-spandex blend knitted fabric or a polyester fiber knitted fabric.

[0039] Implementation of composite knitted fabrics, for example Figures 1-4 As shown, the composite knitted fabric includes an outer wool fiber knitted fabric 4 and an inner synthetic fiber knitted fabric 2, and also includes an adhesive layer 1 disposed between the outer wool fiber knitted fabric 4 and the inner synthetic fiber knitted fabric. The outer wool fiber knitted fabric 4 is adhered and fixed to the outer surface of the inner synthetic fiber knitted fabric 2 by the adhesive layer 1, and the adhesive layer has water-permeable holes 3 distributed on it. In other embodiments of this utility model, the adhesive layer 1 can also be a water-permeable adhesive layer, such as a water-permeable epoxy resin adhesive layer after curing, in which case the adhesive layer does not need to have water-permeable holes distributed on it.

[0040] In this embodiment, the inner synthetic fiber knitted fabric 2 is a nylon-spandex blended knitted fabric (or a polyester fiber knitted fabric).

[0041] The adhesive layer includes multiple horizontal adhesive strips 5 arranged in parallel and multiple vertical adhesive strips 6 arranged in parallel. Each horizontal adhesive strip 5 is intersected with the corresponding vertical adhesive strip 6. The water-permeable hole is formed between two adjacent horizontal adhesive strips 5 and two adjacent vertical adhesive strips 6. The water-permeable hole is a diamond-shaped hole 18.
