Abstract: The present application provides an absorption product and a manufacturing method therefor, and a production system for manufacturing the absorption product. According to the manufacturing method for the absorption product of the present application, cutting of a sensing layer and a leak-proof bottom layer is controlled according to an in-place signal of a same cutting mark, such that the orthographic projection of a sensing strip on the leak-proof bottom layer intersects with an accommodating groove used for accommodating a data reader. The end of the sensing strip in contact with the absorption core is conducted by means of the absorption liquid, and the data reader can obtain conduction data of the sensing strip so as to send out a replacement prompt, such that the absorption product can be replaced timely according to the replacement prompt.

Abstract: A nonwoven absorbent textile article for absorbing liquid includes a first fiber layer having perforated through holes with an area of 10-80% based on total area of the first fiber layer, having a thickness ranging from 0.2-2.0 mm, and having a contact angle with water that is larger than 70° to distribute liquid thereon; and a second fiber layer fixedly connected to the first fiber layer in a hot air through oven by heat bonding and having a contact angle with water that is less than 70° to absorb liquid distributed by the first fiber layer, wherein the first fiber layer includes fibers that are sheath/core fibers or an eccentric bi-component fibers, and wherein the first fiber layer has a basis weight of 5-40 g/m2 and the second fiber layer has a basis weight of 5-40 g/m2. Contact with the skin of a user has a dryer feel and provides comfort.

Abstract: A three-dimensional nonwoven fabric with a pore structure includes raised regions, recessed regions, and the pore structure. Fiber densities from the raised regions to the recessed regions are gradient. That is, the fiber density of the edges transiting from the raised regions to the recessed regions is higher than that of the tops of the raised regions. Pressure resistance performance of the high-density fiber regions keeps the three-dimensional nonwoven fabric significantly uneven, and quickens liquid permeation and reduces residues, and the three-dimensional nonwoven fabric has a high permeating speed and is dry and comfortable.

Abstract: Provided are a non-woven fabric containing cotton and a method for manufacturing same. The non-woven fabric containing cotton is composed of at least a surface layer and a non-woven fabric reinforcement layer, wherein the surface layer is composed of 30%-100% of cotton fibers in a gram weight of 5-30 g/m2, and the cotton fibers permeate the non-woven fabric reinforcement layer. The non-woven fabric containing cotton can not only maintain the advantages of softness and kindness to skin of the cotton fibers, but can also improve the strength of a spunlace non-woven fabric.

Abstract: Disclosed is a hot air through nonwoven and a manufacturing method thereof, the hot air through nonwoven comprises a first fiber layer and a second fiber layer that are fixedly connected up and down; the contact angle of the first fiber layer and water is larger than 70°, the thickness of the first fiber layer is 0.2-2.0 mm, the first fiber layer has throughout holes, the area of the throughout holes has 10-80% of the total area of the first fiber layer; the contact angle of the second fiber layer and water is less than 70°; the first fiber layer is used to distribute the liquid thereon to the second fiber layer, the second fiber layer is used to absorb the liquid from the first fiber layer.

Abstract: This invention relates to a method for preventing a copy of document, belonging to a technical field of entire copy protection of document. In the prior art, for some important documents, specially the secret ones, the reproduction of this kind of document is usually prohibited by its owner because of the security. But the technique in the prior art can not solve the problem of preventing unauthorized reproduction. The method of the present invention is intended to embed a shading pattern under the original image of anti-copy document by an application program installed in the copy device, and decide whether the document can be copied legally or not. By the method of present invention, it is possible to detect the watermark information of the anti-copy document accurately and quickly, and prevent the reproduction of the anti-copy document thoroughly. Moreover, an additional memory space is no need.
