Embodiment Construction

[0013] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0014] An embossed perforated non-woven fabric, which is formed by hot-rolling and bonding a surface layer 1 made of polypropylene and a bottom layer 2 made of polypropylene. The surface layer 1 is a fine-denier fiber of 1.5 denier, and the bottom layer 2 is 2.0 denier. Neil is relatively thick fiber, the upper surface of the surface layer 1 is provided with uniformly arranged semi-spherical protrusions 3, and the middle of every two adjacent protrusions 3 is provided with a conical drainage hole 4 with a large top and a small bottom, and the drainage hole 4 runs through the surface layer 1 and ground floor 2.

[0015] The surface layer 1 of thinner fibers is used as the skin-friendly layer, which is more comfortable and soft in contact with the human skin; the bottom layer 2 of thicker fibers is used as the outer layer, which has high plasticity and is ...

Abstract

The invention discloses punched and embossed non-woven fabric and belongs to the field of non-woven fabric. The punched and embossed non-woven fabric comprises a surface layer made of fine-denier fibers and a bottom layer made of thick-denier fibers and hot-rolled at the lower part of the surface layer, wherein bulges are uniformly distributed on the upper surface of the surface layer, and a downward conical drainage hole is formed between every two adjacent bulges and runs through the surface layer and the bottom layer. Through combination of the drainage holes and the round bulges, the air permeability of the surface layer of the non-woven fabric is enhanced, the affinity and softness are improved when the fabric is contacted with the skin, the surface layer keeps a certain interval with the human skin by means of the budges, liquid absorption and permeation speeds are increased, liquid back permeation is better eliminated, the surfaces of a diaper and a sanitary napkin are drier and cleaner and have good comfort, and red butt phenomena of babies are reduced; through combination of the fibers with different thicknesses, the surface layer is softer, the bottom layer has higher support performance, the forming ratio of the conical drainage holes with a flow guide function is kept more easily, and the cost is lower.

Description

technical field [0001] The invention belongs to the field of nonwoven fabrics, in particular to a perforated embossed nonwoven fabric. Background technique [0002] Non-woven fabric, also known as non-woven fabric or non-woven fabric, is composed of directional or random random fine denier fibers. It is a new generation of environmentally friendly green materials, and the material itself is hydrophobic. Using polypropylene PP pellets as the basic raw material, it is produced through one-step production methods such as 230°C high-temperature melting, spinning, drawing, splitting and laying, hot rolling, hydrophilic treatment, drying, and crimping. Because it has the performance of non-woven fabrics, it also has certain liquid permeability. [0003] In the women's and children's industries such as baby diapers and sanitary napkins, the first surface layer is usually used to quickly penetrate unconscious excreta such as urine and menstrual blood, thereby improving the comfort ...
