Problems solved by technology

[0007] The purpose of the present invention is to solve the deficiencies in the prior art, to overcome the problem that the existing hot-air nonwoven fabric is easy to fluff, to provide a geometric shape that combines points, lines and surfaces on the surface of the nonwoven fabric, and to achieve a good shape. A new type of laminated nonwoven fabric with soft hand feeling, up to the standard thickness, and less prone to hairiness during use, and its device and production method

Embodiment Construction

[0027] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0028] The nonwoven fabric 1 of the present invention is figure 1 It is shown in plan view. This pattern is just one example of the new method of making laminated nonwovens. In the formal production process, laminated non-woven fabrics with different appearance effects can be produced according to the pattern. exist figure 1 Among them, 2 represents the running direction of the device. Laminated nonwovens are produced in machine direction 2. The nonwoven fabric 1 forms two different pattern areas in the running direction of the device, namely the flower pattern formed by the concave-convex area 3 . If you look at the front and back sides respectively, the front raised parts form a surface, and the front concave parts become another surface with raised parts when viewed from the reverse side.

Abstract

The invention discloses a laminated non-woven cloth, an apparatus thereof and its production, and the non-woven cloth is mainly used in personal health nursing materials. The surface of the laminated non-woven cloth presents a well-regulated, continuous and lattice-regulated polygon and the gram weighing range is 18-55 g / m2 and the thickness range is 0.8-3.0 mm. The laminated non-woven cloth has advantages of soft hand feeling, standard thickness and handsome pattern on the surface. The surface hairiness of the hot-blast non-woven cloth produced by the production method of the corresponding apparatus and three rollers is smoothed out. The surface of the non-woven cloth presents a concavo-convex pattern simultaneously. The production method overcomes the problem that the prior hot-blast non-woven cloth is easy to fluff.

Description

technical field [0001] The invention relates to a method for making a new type of nonwoven fabric, in particular to a laminated nonwoven fabric capable of reducing hairiness and improving its physical comfort and structural aesthetics while keeping the original softness and strength unchanged. The production method, the nonwoven fabric is mainly used in personal hygiene care products. Background technique [0002] Thermally bonded nonwovens are widely used in feminine hygiene products and baby diapers, usually on the top or second layer, which absorb body fluids (menstrual fluid, urine) quickly and guide them as evenly as possible into the underlying layer The absorbent core, in this way, both keeps the skin dry and prevents lateral leakage of body fluids. [0003] Air-through nonwoven fabric is a kind of thermal bonding process. It is widely used in personal hygiene care products because it feels soft and fluffy and can make users feel comfortable. The hot-air nonwoven fa...
