Description

Technical Field

[0001] The utility model relates to the field of curtain fabrics, and more particularly to an anti-slack pleated curtain material structure. Background Art

[0002] Pleated curtain material is used to make pleated curtain window coverings. It has a folding structure that can form a compact fold when retracted and form a light-blocking barrier when unfolded.

[0003] The pleated curtain material in the prior art is pressed from a fabric and has a wavy shape. In order to prevent the pleated curtain material from stretching, deforming or relaxing after being folded multiple times, a composite fabric with a harder material is usually used in the prior art, and its cost is often high. Ordinary spunbond non-woven fabrics have a lower cost, but the pleated curtain material made therefrom often becomes loose and stretched after being folded multiple times, resulting in the pleated curtain material made of non-woven fabric being unable to maintain the initial wavy shape and folding effect.

[0004] Therefore, new solutions need to be proposed to solve this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of the utility model is to provide an anti-slack pleated curtain material structure with good elasticity, which avoids the curtain material from being loosened and deformed after long-term use.

[0006] The above technical purpose of the present invention is achieved through the following technical solutions: an anti-slack pleated curtain material structure, comprising a plurality of folding units, wherein the folding unit comprises a folding portion and two bonding portions, a fold is provided in the middle of the folding portion, and the folding portion is divided into two openable and closable wings by the fold, the two bonding portions are located at the edges of the two wings, the folding portion and the bonding portion are integrally formed and the folding portion and the bonding portion are smoothly connected, and the bonding portions between adjacent folding units are fixedly connected.

[0007] The present invention is further configured as follows: the folding unit includes a folded state and an unfolded state. When the folding unit is in the folded state, the two wings in the folding unit are attached to each other. When the folding unit is in the unfolded state, the two wings in the folding unit are flipped along the crease, and bending deformation is generated between the folding portion and the adhesive portion. In the natural state, the folding unit is in a folded state.

[0008] The utility model is further configured as follows: the folding unit is formed by folding non-woven fabric.

[0009] The utility model is further configured such that: the bonding portions between adjacent folding units are connected by hot melt adhesive or ultrasonic welding.

[0010] In summary, the present invention has the following beneficial effects:

[0011] The utility model divides the curtain material into several folding units, and the folding unit includes a folding part and two bonding parts. The folding part and the bonding part are integrally formed and smoothly connected to each other. The curtain material can be stretched. When stretched, the folding unit in each folding unit becomes an unfolded state, and the two wings in the folding unit are flipped along the folding line, which can increase the width of the folding part, thereby stretching the curtain material. At the same time, the folding part and the bonding part will also receive tension and bend and deform. Since there is no crease between the folding part and the bonding part, when the tension is removed, the folding part and the bonding part have a tendency to return to a smooth state, which can provide elasticity for the curtain material to return to its original shape, thereby making the curtain material more elastic and avoiding the problem of loosening and deformation of the curtain material after long-term use.

[0016] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0017] Embodiment: A structure for an anti-slack pleated curtain material, such as Figure 1-3 As shown, it includes several folding units, which include a folding portion 1 and two adhesive portions 2. A fold 3 is provided in the middle of the folding portion 1. The folding portion 1 is divided into two openable and closable flaps 4 by the fold 3. The two adhesive portions 2 are located at the edges of the two flaps 4. The folding portion 1 and the adhesive portion 2 are integrally formed and smoothly connected to each other. The adhesive portions 2 between adjacent folding units are fixedly connected. The folding unit includes a folded state and an unfolded state. When the folding unit is in the folded state, the two flaps 4 in the folding unit are attached to each other. When the folding unit is in the unfolded state, as shown in FIG. Figure 2As shown, the two wings 4 in the folding unit are flipped along the fold 3, and a bending deformation occurs between the folding portion 1 and the bonding portion 2, so that the curtain material can be stretched. When stretched, the folding unit in each folding unit becomes unfolded, and the two wings 4 in the folding unit are flipped along the fold 3, which can increase the width of the folding portion 1, thereby stretching the curtain material. At the same time, the folding portion 1 and the bonding portion 2 will also receive tension and bend deformation. Since there is no fold 3 between the folding portion 1 and the bonding portion 2, and the folding unit is in a folded state in a natural state, when the tension is removed, the folding portion 1 and the bonding portion 2 have a tendency to return to a smooth state, which can provide elastic force for the curtain material to return to its original shape, thereby making the curtain material more elastic and avoiding the problem of loosening and deformation of the curtain material after long-term use.

[0018] The folding unit is formed by folding non-woven fabric. Non-woven fabric has a low production cost and good sound absorption and light-shielding properties. In addition, non-woven fabric can present various colors and patterns through dyeing and printing processes, providing a variety of decorative options and better use effects.

[0019] The bonding parts 2 between adjacent folding units are connected by hot melt adhesive or ultrasonic welding. Both hot melt adhesive and ultrasonic welding have strong connection capabilities, which can effectively fix adjacent folding units firmly together, ensuring that the curtain material will not easily separate or loosen during use, thereby improving the overall durability and service life.

[0020] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
