A seamless anti-peeling structure for functional clothing and its manufacturing process

Abstract

A seamless, anti-peeling structure for functional clothing and its manufacturing process, the structure comprising, from bottom to top, a bottom fabric layer, an adhesive layer, and a waterproof fabric layer; a landslide is provided at the cross-section of the adhesive layer and the waterproof fabric layer, the height of the landslide being greater than the thickness of the adhesive layer. The present invention uses a high-melting, cold-mirror colloid material, which is attached to the incision of the overflowing composite fabric. After a hot-pressing treatment, the incision is sealed and the "step" is eliminated. A low-temperature rapid cooling process is then added to form the colloid in one step, thereby avoiding the colloid's rebound force, thereby generating a landslide at the incision joint. The structure reduces the frontal friction of external forces, reduces external force friction by reducing the height difference, and seals the fabric incision. The incision is not exposed, thus avoiding degumming, separation, and tearing at the composite fabric joint.

Description

Technical Field

[0001] The invention relates to a seamless laminating and anti-peeling structure of functional clothing and a manufacturing process thereof, belonging to the technical field of seamless laminating of fabrics. Background Art

[0002] Functional clothing, also known as a windbreaker, is essential gear for outdoor enthusiasts. The strength of its seamless fit is key to its overall performance. Its functionality lies in its windproof, waterproof, and breathable properties. Some call it a windbreaker or raincoat, and in foreign catalogs, it's called a parka. As the name suggests, it's clothing for mountaineering and summits. Whether sitting in damp areas or walking in wind and rain, it effectively blocks rain, frost, and snow, preventing them from penetrating and chilling you. Winter weather is often unpredictable, especially with cold winds that blow almost daily. A windbreaker effectively prevents these winds from entering.

[0003] To ensure functional clothing achieves this effect, all seamless joints must be free of debonding, separation, and tearing, otherwise rain and cold winds could harm the wearer. However, conventional seamless joints currently carry the risk of debonding and peeling. We randomly sampled jackets from the market and subjected them to a simulated home wash test: washing at room temperature for 45 minutes each time, 15 times. During the wash process, we found that parts such as cuffs, hems, brims, and fitted pockets were prone to peeling and even falling off.

[0004] The reason for this is that traditional seamless lamination methods use high-temperature double-sided tape attached to the backing of the fabric at the joint. The fabric is then cut using a laser or knife. The cut sections are then bonded together using a high-temperature pressing process. Waterproof fabrics are typically composite fabrics, with either three or two layers, held together by lamination. The fabric itself has a certain thickness, and with the high-temperature double-sided tape applied to the back, this creates a cross-section at the cut. Furthermore, in traditional production processes, the double-sided tape rebounds during the cooling process after the high-temperature setting process, resulting in a four- or three-layer cross-section. When the fabric is bonded to a flat surface or its own material, this creates a height difference, exposing the outer fabric layer. These exposed cuts are precisely where the wearer is most likely to experience friction during wear, such as cuffs, hems, hat brims, and fitted pockets. These areas generate relative friction during movement, causing the cut layers to separate. Once the fabric separates or falls off, it loses its inherent windproof and waterproof effects, and also affects the overall appearance of the garment.

[0005] The analysis of the separation of the seamless joints of the jacket shows that the main reason is that the fabric has a height difference after being fitted, and a "step" appears in the plane itself, such as Figure 1 As shown in the figure, the presence of the "step" creates significant external friction during washing and wearing, which causes the garment to separate. The solution to this problem is to minimize friction, primarily by reducing the height difference.

[0006] Therefore, a functional clothing seamless fitting anti-peeling structure and a manufacturing process thereof are invented to solve the above problems. Summary of the Invention

[0007] Aiming at the problem that the joints of functional clothing are easily peeled off, the present invention provides a seamless joint anti-peeling structure of functional clothing and a manufacturing process thereof.

[0008] The technical solution adopted by the present invention is: a seamless fitting anti-peeling structure for functional clothing, which includes, from bottom to top, a bottom fabric layer, an adhesive layer and a waterproof fabric layer; a landslide is provided at the cross-section of the adhesive layer and the waterproof fabric layer, and the height of the landslide is greater than the thickness of the adhesive layer.

[0009] A preferred technical solution is that the landslide is made of the same material as the adhesive layer and is integrally provided.

[0015] Step 2: Place the semi-finished product on an auxiliary pad and heat-press it using a hot press;

[0016] Step 3: Maintain the hot pressing state until the colloid melts until the fluid colloid overflows from the cross section under pressure;

[0017] Step 4: Rapidly cool the composite fabric at low temperature to prevent the colloid from rebounding, and wait for a landslide to form at the cross section of the composite fabric to complete the edge sealing of the cross section of the composite fabric;

[0018] Step 5: Perform routine washing and tearing tests on the composite fabric after edge sealing to observe whether there is degumming, separation and tearing and record them.

[0019] The preferred technical solution is: in step 1, the cross-sectional incision of the colloid layer is located 0.2 to 0.8 cm outside the cross-sectional incision of the waterproof fabric layer.

[0020] The preferred technical solution is: in step 2, the auxiliary pad includes a smooth temperature-resistant layer, a soft high-temperature-resistant silicone layer, a support layer and a pressure buffer layer from top to bottom.

[0021] The preferred technical solution is: in step 2, the parameters of the hot pressing treatment are: temperature 150° C., pressure 3.2 kg, and hot pressing time 18 s.

[0022] The preferred technical solution is: in step 4, the low-temperature rapid cooling is carried out by cold pressing treatment, and the parameters of the cold pressing treatment are: temperature 5~8°C, pressure 3kg, and cold pressing time 5s.

[0023] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art:

[0024] The present invention adopts a high-melting, cold-mirror colloid material, which is attached to the incision of the overflowed composite fabric. After hot pressing treatment, the incision edge is sealed and the "step" is eliminated. Then a low-temperature rapid cooling process is added to form the colloid in one step, thereby avoiding the rebound force of the colloid, thereby causing a landslide at the incision joint, structurally reducing the frontal friction of external force, reducing external force friction by reducing the principle of reducing the height difference, so that the fabric incision is sealed, the incision is not exposed, and the composite fabric joint is avoided from degumming, separation and tearing.

[0031] Example: Figure 2 The figure shows a seamless, anti-peel structure for functional clothing. From bottom to top, the structure comprises a base fabric layer 1, an adhesive layer 2, and a waterproof fabric layer 3. A landslide 4 is provided at the cross section between the adhesive layer 2 and the waterproof fabric layer 3. The height of the landslide 4 is greater than the thickness of the adhesive layer 2. The landslide 4 reduces external friction by minimizing height differences. The landslide 4 seals the fabric cut edge, preventing it from being exposed and preventing debonding, separation, and tearing at the composite fabric joint.

[0032] The preferred embodiment is: Figure 2 As shown, the slope 4 is made of the same material as the adhesive layer 2 and is integrally formed. The slope 4 is formed by melting and overflowing the material of the adhesive layer 2, ensuring a strong structure and a complete edge seal at the incision, thereby preventing debonding, separation, and tearing at the joint.

[0033] The preferred embodiment is: Figure 2 As shown, the inner side of the landslide 4 is bonded to the cross section of the waterproof fabric layer 3. After the colloid is melted by hot pressing, it is bonded to the cross section of the waterproof fabric layer 3, ensuring a strong and wear-resistant structure and avoiding debonding, separation and tearing at the bonding point.

[0034] The preferred embodiment is that the material of the adhesive layer 2 is high temperature glue, which is a high melting point, cold mirror surface colloid material, and imported Permatex fluid high temperature glue can be used.

[0035] In a preferred embodiment, the height of the slope 4 is greater than or equal to the height of the waterproof fabric layer 3. Optimally, the slope 4 should be the same height as the waterproof fabric layer 3, eliminating any drop and preventing debonding, separation, and tearing at the joints. However, multiple process tests are required during processing to ensure optimal product performance.

[0036] A manufacturing process for a seamless anti-peeling structure of functional clothing, comprising the following steps:

[0037] Step 1: Place a high-melting colloid layer between base fabric layer 1 and waterproof fabric layer 3 to form a semi-finished composite fabric. The cross-sectional cut of the colloid layer should be located 0.2-0.8 cm outside the cross-sectional cut of waterproof fabric layer 3 (that is, the colloid layer should be attached 0.2-0.8 cm above the cross-sectional cut of the composite fabric). Imported Permatex fluid high-temperature adhesive can be used for the colloid layer.

[0038] Step 2: Place the semi-finished product on an auxiliary pad. The overall structure consists of four layers: a smooth, non-porous, heat-resistant layer with a thickness of 4mm; a second layer of soft, high-temperature-resistant silicone with a thickness of 4mm; a third layer of support layer, heat-resistant and hard, with a thickness of 3mm; and a fourth layer of pressure-absorbing layer, made of the same material as the second layer, with a thickness of 2mm. The product is then hot-pressed using a hot press. The hot-pressing parameters are: temperature 150°C, pressure 3.2kg, and pressing time 18 seconds. The auxiliary pad ensures that the colloid is fully dissolved and that the landslide 4 is evenly formed.

[0039] Step 3: Maintain the hot pressing state until the colloid melts until the fluid colloid overflows from the cross section under pressure;

[0040] Step 4: The composite fabric is rapidly cooled at low temperature to prevent the colloid from rebounding, and a landslide 4 is formed at the cross section of the composite fabric to complete the edge sealing of the cross section of the composite fabric; wherein, the low temperature rapid cooling adopts a cold pressing treatment, and the parameters of the cold pressing treatment are: temperature 5~8℃, pressure 3kg, and cold pressing time 5s.

[0041] Step 5: Perform routine washing and tearing tests on the composite fabric after edge sealing to observe whether there is degumming, separation and tearing and record them.

[0042] In order to ensure the process effect, hot pressing and cold pressing can use the same press equipped with cold pressing platens and hot pressing platens. When the hot pressing of the hot pressing platen is completed within the specified time, the cold pressing platen will be switched in time to quickly cool the pressed surface.

[0043] The present invention adopts a high-melting, cold-mirror colloid material, which is attached to the incision of the overflowed composite fabric. After hot pressing treatment, the incision edge is sealed and the "step" is eliminated. Then a low-temperature rapid cooling process is added to form the colloid in one step, thereby avoiding the rebound force of the colloid, thereby causing a landslide at the incision joint, structurally reducing the frontal friction of external force, reducing external force friction by reducing the principle of reducing the height difference, so that the fabric incision is sealed, the incision is not exposed, and the composite fabric joint is avoided from degumming, separation and tearing.

Their purpose is to enable those skilled in the art to understand the present invention and implement it accordingly. They are not intended to limit the scope of protection of the present invention. Therefore, all equivalent modifications or variations made by persons skilled in the art without departing from the spirit and technical concepts disclosed herein are intended to be covered by the claims of the present invention.
