Description

Technical Field

[0001] This utility model relates to the technical field of reinforced seam structure for high-density woven windproof fabrics, specifically a reinforced seam structure for high-density woven windproof fabrics. Background Technology

[0002] High-density woven windproof fabrics achieve windproof and warm functions through optimized yarn technology and fabric structure. The embedded spinning technology developed by the team at Wuhan Textile University breaks through traditional limitations, spinning cashmere short fibers into the world's finest yarn to create high-count, high-density fabrics. Its core principle lies in controlling airflow: the higher the fabric density, the more static air is retained, resulting in superior warmth retention. Outer layers of down jackets, windbreakers, and outdoor jackets utilize this high-density structure to prevent down from escaping and to lock in warmth.

[0003] Existing high-density woven windproof fabrics are usually joined by sewing, but sewing alone can easily create gaps, which can lead to air leakage and water seepage.

[0004] Therefore, a reinforced seam structure in a high-density woven windproof fabric is needed to improve the above-mentioned problems. Utility Model Content

[0005] The purpose of this invention is to provide a reinforced seam structure for a high-density woven windproof fabric to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A reinforced seam structure for a high-density woven windproof fabric includes a first seam edge fabric, characterized in that: a second seam edge fabric is provided on the right side of the first seam edge fabric; a connecting fabric is provided between the first and second seam edge fabrics; a first thin film layer is provided on the upper side between the first and second seam edge fabrics; a second thin film layer is provided on the lower side between the first and second seam edge fabrics; a first adhesive fabric is provided on the upper side of the first thin film layer; a second adhesive fabric is provided on the lower side of the second thin film layer; a first protective fabric is provided on the upper side of the first adhesive fabric; and a second protective fabric is provided on the lower side of the second adhesive fabric.

[0008] As a preferred embodiment of this utility model, the left side of the connecting fabric is located on the base surface of the first seam edge fabric, and the right side of the connecting fabric is located at the bottom of the second seam edge fabric.

[0009] As a preferred embodiment of this utility model, the first film layer and the second film layer are made of polyolefin material.

[0010] Through the above technical solutions, the nanoscale microporous structure of polyolefin material allows water vapor molecules to pass through while preventing liquid water from penetrating. This "breathing function" can effectively expel human sweat and avoid stuffiness. The film's chemical corrosion resistance, UV resistance, and abrasion resistance can improve the durability of clothing in complex environments such as outdoor and medical settings, and extend its service life. After the film is combined with the fabric, it can maintain waterproofness in rain and snow environments, while regulating body temperature through the breathable structure, thus solving the "stuffy and damp" problem of traditional coated clothing.

[0011] As a preferred embodiment of this utility model, the first adhesive cloth and the second adhesive cloth are made of double-sided adhesive backing material.

[0012] Through the above technical solutions, the double-sided adhesive backing material uses low-formaldehyde, biodegradable hot melt adhesive, which meets the standards for ecological textiles, adapts to the needs of green consumption, improves the efficiency of automated production, and optimizes the uniformity of the adhesive layer to reduce the risk of adhesion failure.

[0013] As a preferred embodiment of this utility model, the materials of the first protective cloth and the second protective cloth are the same as the materials of the first seam edge cloth and the second seam edge cloth, respectively.

[0014] As a preferred embodiment of this utility model, the left side of the connecting fabric is sewn to the first seam edge fabric via a connecting line, and the right side of the connecting fabric is sewn to the second seam edge fabric via a connecting line.

[0015] The above technical solution increases the stability of the connection between the first and second seam edge fabrics.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] In this invention, the reinforced seam structure of the high-density woven windproof fabric allows the first and second seam edge fabrics to be connected via a connecting cloth. Heating allows the first protective fabric, second protective fabric, first film layer, second film layer, first adhesive cloth, and second adhesive cloth to be bonded to the first and second seam edge fabrics respectively, resulting in a better sealing effect and preventing air leakage or water seepage. Furthermore, the connecting cloth ensures a more stable connection and a longer service life. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, and several embodiments of the utility model will be provided. However, the utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the utility model more thorough and complete.

[0024] For examples, please refer to Figure 1-3 This utility model provides a technical solution:

[0025] A reinforced seam structure for a high-density woven windproof fabric includes a first seam edge fabric 1, a second seam edge fabric 2 disposed on the right side of the first seam edge fabric 1, a connecting fabric 3 disposed between the first seam edge fabric 1 and the second seam edge fabric 2, a first thin film layer 4 disposed on the upper side between the first seam edge fabric 1 and the second seam edge fabric 2, a second thin film layer 5 disposed on the lower side between the first seam edge fabric 1 and the second seam edge fabric 2, a first adhesive fabric 6 disposed on the upper side of the first thin film layer 4, a second adhesive fabric 7 disposed on the lower side of the second thin film layer 5, a first protective fabric 8 disposed on the upper side of the first adhesive fabric 6, and a second protective fabric 9 disposed on the lower side of the second adhesive fabric 7.

[0026] The connecting fabric 3 is positioned on the base surface of the first seam fabric 1 on the left side, and on the bottom of the second seam fabric 2 on the right side. The first film layer 4 and the second film layer 5 are made of polyolefin material. The nanoscale microporous structure of the polyolefin material allows water vapor molecules to pass through for breathability, while preventing liquid water from penetrating to achieve waterproofing. This "breathing function" can effectively expel human sweat and avoid stuffiness. The film's chemical corrosion resistance, UV resistance, and abrasion resistance properties, such as PTFE film, can improve the durability of clothing in complex environments such as outdoor and medical settings, and extend its service life. After the film is combined with the fabric, it can maintain waterproofing in rain and snow environments, while regulating body temperature through the breathable structure, solving the "stuffy and damp" problem of traditional coated clothing.

[0027] Among them, the first adhesive cloth 6 and the second adhesive cloth 7 are made of double-sided adhesive backing material. The double-sided adhesive backing material is made of low formaldehyde and biodegradable hot melt adhesive, which meets the standards of ecological textiles, adapts to the needs of green consumption, improves the efficiency of automated production, and optimizes the uniformity of the adhesive layer to reduce the risk of adhesive failure.

[0028] The first protective fabric 8 and the second protective fabric 9 are made of the same material as the first seam edge fabric 1 and the second seam edge fabric 2, respectively. The left side of the connecting fabric 3 is sewn to the first seam edge fabric 1 by a connecting line, and the right side of the connecting fabric 3 is sewn to the second seam edge fabric 2 by a connecting line, which increases the stability of the connection between the first seam edge fabric 1 and the second seam edge fabric 2.

[0029] The working process of this utility model is as follows: Using the reinforced seam structure of the high-density woven windproof fabric designed in this scheme, the first seam edge fabric 1 and the second seam edge fabric 2 are connected by a connecting fabric 3. The first adhesive fabric 6 and the second adhesive fabric 7 are heated. At room temperature, the first adhesive fabric 6 and the second adhesive fabric 7 are not adhesive; they need to be melted by heating (usually 120-140℃) to produce an adhesive effect. This process is environmentally friendly and leaves no solvent residue. After heating, the first protective fabric 8, the second protective fabric 9, the first film layer 4, the second film layer 5, the first adhesive fabric 6, and the second adhesive fabric 7 are respectively bonded to the first seam edge fabric 1 and the second seam edge fabric 2, thereby improving the sealing effect and preventing air leakage and water seepage. Furthermore, the connecting fabric makes the connection more stable, extending its service life.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
