Functional garment seamless bonded peel resistant structure

Abstract

This utility model discloses a functional seamless adhesive anti-peeling structure for clothing, comprising an outer layer, a middle layer, and an inner layer. The middle layer is located between the outer and inner layers, and both its upper and lower sides are provided with two protrusions. The outer and inner layers are each provided with a first protrusion on the side closest to the middle layer. In this functional seamless adhesive anti-peeling structure, the two protrusions and one protrusion are intermittently staggered, increasing the friction between the outer, middle, and inner layers and improving peel resistance. The edge sealing is located at the edge of the fabric cut, and the edge sealing and adhesive layer are fused together by heat pressing. The edge sealing wraps around the edge of the fabric cut, and its outer side has an arc-shaped structure, structurally reducing frontal friction from external forces. By reducing height differences, external force friction is reduced, ensuring the fabric cut is sealed and not exposed, effectively solving the problems of easy delamination, detachment, and tearing at the bonding points of composite fabrics.

Description

Technical Field

[0001] This utility model relates to the field of anti-peeling technology for clothing, specifically a functional seamless adhesive anti-peeling structure for clothing. Background Technology

[0002] Functional clothing is designed to meet specific functional requirements, and it demands relatively high quality and advanced technology. This type of clothing includes workwear with scientific and technological functions that provide protection in special environments. Waterproof jackets are a type of functional clothing. The strength of the seamless fit of a waterproof jacket is crucial to the entire garment, and its functionality lies in windproofing, waterproofing, and breathability.

[0003] To ensure a rain jacket achieves windproof, waterproof, and breathable properties, all seamless seams must be free from delamination, detachment, or tearing. Otherwise, rain and cold winds will harm the wearer. However, the current conventional seamless seaming method involves attaching high-temperature double-sided adhesive to the back layer of the fabric at the seam, then cutting it using laser or a cutter. The cut sections are then bonded to the corresponding areas using high-temperature pressing. Waterproof fabrics are generally composed of composite materials with a certain thickness, resulting in unevenness and exposed cross-sections of the outer fabric. These exposed cuts are precisely where the wearer is most prone to friction during wear, such as cuffs, hem, hood brim, and fitted pockets. Prolonged friction can cause the cut layers to separate, affecting the overall windproof and waterproof performance of the rain jacket, as well as its overall appearance. Utility Model Content

[0004] The purpose of this utility model is to provide a seamless adhesive anti-peeling structure for functional clothing, in order to solve the problem mentioned in the background art that the cut position of functional clothing on the market is prone to height difference, resulting in the exposure of the cross-section of the outer layer fabric.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a functional garment seamless adhesive anti-peeling structure, comprising an outer layer, a middle layer and an inner layer, wherein the middle layer is located between the outer layer and the inner layer, and both the upper and lower sides of the middle layer are provided with protrusions two, and both the outer layer and the inner layer are provided with protrusions one on the side near the middle layer, and the edges of the outer layer, the middle layer and the inner layer are provided with sealing edges.

[0006] Preferably, the first protrusion and the second protrusion are intermittently staggered.

[0007] Preferably, the diameter of both the first protrusion and the second protrusion is 0.2 mm, the distance between two adjacent second protrusions is 2 mm, and the distance between two adjacent first protrusions is 2 mm.

[0008] Preferably, the outer layer is a waterproof fabric; and / or, the middle layer is a polyester fiber reinforced mesh fabric; and / or, the inner layer is a moisture-wicking and quick-drying lining fabric.

[0009] Preferably, the upper and lower sides of the intermediate layer are coated with an adhesive layer.

[0010] Preferably, the thickness of the edge sealing layer is greater than the sum of the thicknesses of the intermediate layer and the adhesive layer.

[0011] Preferably, the edge sealing is a UV-cured sealing strip, and the adhesive layer material is a high-temperature adhesive.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The edge sealing is located at the edge of the fabric cut. The edge sealing and the adhesive layer are fused together by heat pressing. The edge sealing wraps around the edge of the fabric cut, and the outer side of the edge sealing has an arc structure, which reduces the front friction of external forces. By reducing the height difference, external force friction is reduced, and the fabric cut is sealed, so that the cut is not exposed. This effectively solves the problem of easy delamination, separation and tearing at the bonding point of composite fabrics. At the same time, the two protrusions are intermittently and alternately set with the first protrusion, which can increase the friction between the outer layer, middle layer and inner layer, and improve the peeling resistance.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-4 The present invention provides the following technical solution:

[0021] A functional garment seamless adhesive anti-peeling structure includes an outer layer 1, a middle layer 3, and an inner layer 4. The middle layer 3 is located between the outer layer 1 and the inner layer 4. The middle layer 3 has two protrusions 5 on both its upper and lower sides. The outer layer 1 and the inner layer 4 have one protrusion 6 on the side closest to the middle layer 3. The protrusions 6 and 5 are intermittently staggered. The diameter of both protrusions 6 and 5 is 0.2 mm. The distance between two adjacent protrusions 5 is 2 mm, and the distance between two adjacent protrusions 6 is 2 mm.

[0022] The intermittent staggered arrangement of bump 6 and bump 5, through the micro-bump structure, can improve the peeling resistance, increase the friction between the outer layer 1, the middle layer 3 and the inner layer 4, and make the layers more firmly bonded.

[0023] The outer layer 1, the middle layer 3 and the inner layer 4 are provided with edge sealing 2. The outer side of edge sealing 2 is an arc-shaped structure, which reduces the front friction of external forces in terms of structure. By reducing the height difference, the friction of external forces is reduced, so that the fabric cut is sealed and the cut is not exposed.

[0024] The upper and lower sides of the intermediate layer 3 are coated with an adhesive layer 7. The adhesive layer 7 is made of high-temperature adhesive, which is a high-melting, cold mirror-like adhesive material. Imported Permatex fluid high-temperature adhesive can be selected.

[0025] After hot pressing, a low-temperature rapid cooling process is used to bond and fix the outer layer 1, the middle layer 3, and the inner layer 4. At the same time, the adhesive of the edge sealing layer 2 and the adhesive layer 7 is formed in one step, thereby avoiding the elasticity of the adhesive and sealing the edges of the fabric. The edges are not exposed, effectively solving the problems of easy delamination, separation, and tearing at the bonding points of composite fabrics.

[0026] The outer layer 1 is a waterproof fabric, the middle layer 3 is a polyester fiber reinforced mesh fabric, the inner layer 4 is a moisture-wicking and quick-drying lining fabric, and the edge sealing 2 is a UV-cured sealing strip. The thickness of the edge sealing 2 is greater than the sum of the thicknesses of the middle layer 3 and the adhesive layer 7.

[0027] The best result is when the side edge of the edge banding 2 is flush with the outer layer 1 and the inner layer 4. At this point, there is no difference in height, which can better prevent the adhesive from coming off, separating, or tearing at the bonding point. However, multiple tests should be conducted during processing to ensure the best product effect.

[0028] During the manufacturing process, bump 5 and bump 6 are first made. Pressure is applied to the three layers of fabric, outer layer 1, middle layer 3 and inner layer 4, using mechanical embossing equipment to form regular micro bumps.

[0029] Then, a high-melting-point adhesive layer is set between the inner layer 4 and the middle layer 3, and a high-melting-point adhesive layer is set between the middle layer 3 and the outer layer 1. During the bonding process of the outer layer 1, the middle layer 3 and the inner layer 4, the second protrusion 5 and the first protrusion 6 are misaligned to obtain a semi-finished composite fabric. UV glue is applied around the edges and kept under hot pressure. When the adhesive layer 7 melts, the fluid glue overflows from the cross-section under pressure and mixes with the UV glue to form an integral structure. Finally, the composite fabric is rapidly cooled at low temperature to prevent the glue from rebounding. The cross-section of the composite fabric is sealed. The sealed composite fabric is subjected to conventional water washing and tearing tests to observe and record whether there is any delamination, separation and tearing.

[0030] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
