Hydrolytic thin products and producing method thereof

Abstract

Disclosed is a water disintegratable sheet of which fibers are hydroentangled about each other. The water disintegratable sheet includes: at least one kind of primary fibers having a fiber length of at most 10 millimeter; and bast / leaf fibers having a Canadian Standard freeness value of at most 600 milliliter and a fiber length of at most 10 millimeter.

Description

technical field [0001] The present invention relates to a hydrodisintegratable thin-layer product whose fibers can be continuously dispersed with a large amount of water. More particularly, the present invention relates to a method that can ensure an appropriate balance between hydrolysis and strength by including bast / vein fibers. Balanced hydrolyzable thin-layer product. Background technique [0002] For wet tissue products for wiping excretion parts of the body, etc., and wet wipe products for cleaning sanitary utensils, etc., it is preferable to use products having hydrolyzability. Moreover, for absorbent articles such as sanitary napkins, panty liners, and disposable diapers, the surface sheet covering the surface of the absorbent layer and the inner sheet covering the inner surface of the absorbent layer are also most suitable It is best to use hydrolyzable products. It is also preferable to use a hydrolyzable thin layer product for packaging these absorbent articles...

Problems solved by technology

[0008] And because the pulp fiber after beating and mixing is quite fine, so easily come off by the inboard of fiber fabric when forming fiber fabric, and when implementing high-pressure water treatment, also can come off by fiber fabric, so its manufacturing utilization rate is not good
