Non-woven fabric coil with printed patterns

Abstract

The invention discloses a non-woven fabric coil with printed patterns. Air permeability of the non-woven fabric coil with the printed patterns is 0-3500L / m<2> / s. The non-woven fabric coil with the printed patterns comprises a top fiber layer, at least one middle printing layer and a bottom fiber layer, which are connected in sequence, wherein fineness of fibers used in the top fiber layer and the bottom fiber layer is larger than 1.0D, fineness of fibers used in the at least one middle printing layer is less than 0.3D, the ink printed patterns of one color or more than one color are printed on the at least one middle printing layer, the fibers used in the top fiber layer, the at least one middle printing layer and the bottom fiber layer are shaped once in heat bonding mode through hot pressing points after the fibers are spread and sprayed to the layers, and the area of a concave area formed by the hot pressing points is 5-70% of the total area. The non-woven fabric coil with the printed patterns can effectively prevent the problems that ink fades, skin sensibility is easily caused and the like.

Description

technical field [0001] The invention belongs to the technical field of non-woven fabrics, and in particular relates to a non-woven fabric roll material with printed patterns. Background technique [0002] Mechanical fasteners are well known in the art and may also be referred to as "hook and loop" fasteners. Mechanical fasteners consist of two separable parts, one of which has terminal projections or a J-shape on a base. The hook part and the other part is a ring part with a ring-shaped functional layer. When the hook and the loop are pressed together, since the hook is embedded in the loop and intertwined with the loop, the obtained fastener can be tightly combined and not easy to fall off. The hook and loop can be separated again when a suitable peeling force is applied thereto. Through the combination and separation between the hook and loop, repeated use can be realized. [0003] The rings used for baby diapers usually need to have exquisite printing patterns, which a...

Problems solved by technology

However, due to the plastic film it contains, when it is used in the field of disposable hygiene products, such as diapers, its air permeability will be affected, and it is not easy to adjust the setting to meet the unique air permeability requirements, which is not conducive to the subsequent use of rings. Processing of diapers

As for the ring parts of non-woven fabric substrate, due to the thicker fibers on the printing surface, the pattern definition is not high, the color fastness is poor, and the non-woven fabric printing is more difficult.
