Abstract

The invention discloses a composite elastic sheet as well as a manufacturing method and manufacturing equipment thereof. The composite elastic sheet comprises a first surface layer, a middle elastic layer and a second surface layer which are sequentially compounded, wherein the middle elastic layer is of a layered structure formed by distributing a plurality of continuous elastic fiber filaments or strip-shaped fiber layers side by side, and the middle elastic layer is compounded with the first surface layer and the second surface layer in an intermittent mode. According to the manufacturing method and the manufacturing equipment of the composite elastic sheet, the middle elastic layer is formed on line through an extruder and a wire extruding plate and is intermittently compounded with the first surface layer and the second surface layer in a stretching state, and finally the composite elastic sheet is formed. The manufacturing principle is simple, the formed composite elastic sheet has higher air permeability, the production cost is lower, the stretching ratio can be adjusted in the production process according to the product requirements of practical application, and the composite elastic sheet is suitable for a wider range of applicable disposable hygienic products.

Description

technical field

[0001] The invention relates to the technical field of manufacturing disposable sanitary products, in particular to a composite elastic sheet and its manufacturing method and manufacturing equipment. Background technique

[0002] In the product design of disposable sanitary products, most of the products need to add elastic materials to make the products fit the human body better when worn after forming, ensuring uniform force and comfortable wearing. For example, in baby diaper products, the elastic waist serves a corresponding function.

[0003] Among the current disposable sanitary products, the settings of elastic materials mainly have the following forms:

[0004] (1) Use the elastic film directly. Its advantage is that the stretching ratio is large, which can reach more than 3 times; but the disadvantage is that the elastic film is not breathable, and the formed product has poor air permeability and poor user experience; and when used on production eq...
