Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabrics, in particular to a sandwich layer longitudinal elastic non-woven fabric structure. Background Art

[0002] Longitudinal stretch non-woven fabric is a special non-woven fabric material. The same type of longitudinal stretch non-woven fabric on the market currently uses two layers of spunbond PP non-woven fabric and spandex yarn, which are compounded with glue. It has the disadvantages of hard hand feel and poor sweat absorption performance of PP material, which has long plagued the market. In addition, the same type of longitudinal stretch non-woven fabric on the market currently uses glue compounding technology, and the product not only has odor, but also has environmental problems and high costs in the production process. Therefore, we propose a sandwich layer longitudinal stretch non-woven fabric structure. Utility Model Content

[0003] The purpose of the utility model is to provide a sandwich layer longitudinal elastic non-woven fabric structure to solve the above-mentioned deficiencies in the technology.

[0004] In order to achieve the above-mentioned purpose, the utility model provides the following technical solution: a sandwich layer longitudinal elastic non-woven fabric structure, including a first spunbond 3S non-woven fabric, spandex yarn, a two-component meltblown non-woven fabric and a second spunbond 3S non-woven fabric, the spandex yarn and the two-component meltblown non-woven fabric are located between the first spunbond 3S non-woven fabric and the second spunbond 3S non-woven fabric, and the first spunbond 3S non-woven fabric, spandex yarn, two-component meltblown non-woven fabric and the second spunbond 3S non-woven fabric are thermally bonded.

[0005] Furthermore, the first spunbonded 3S nonwoven fabric and the second spunbonded 3S nonwoven fabric are 10 g / m 2 .

[0006] Furthermore, the two-component meltblown nonwoven fabric is 13g / m 2 .

[0007] Compared with the prior art, the beneficial effects of the present invention are:

[0008] 1. The design of the sandwich layer makes the non-woven material have better elasticity and stretchability in the longitudinal direction;

[0009] 2. The spunbond 3S non-woven fabric used in the outer layer provides good strength and stability, while the meltblown non-woven fabric in the inner layer increases softness and moisture absorption, making the material have sufficient strength while maintaining a soft and comfortable feel;

[0010] 3. The composite is made of non-woven fabrics with thermal bonding principle, which is relatively simple in process and has high production efficiency. At the same time, the purely physical composite method avoids the use of chemical adhesives and is more environmentally friendly.

[0011] Combined with the above-mentioned sandwich layer longitudinal elastic non-woven fabric material, on the one hand, it maintains the high elasticity function of the material, and on the other hand, it increases the skin-friendly sweat absorption function and soft feel of the material, and also newly adds the environmental protection performance of the material. This process uses the material properties of the non-woven fabric for pure physical processing, retaining the original spandex yarn and will not use any EVA or PA glue and glue powder. While truly being environmentally friendly and odorless, it also achieves the purpose of saving production costs and improving production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
