Method of producing an absorbent garment, and an absorbent garment produced according to the method

Abstract

A method for continuously producing absorbent garments includes forming a continuous multi-component production web; and cutting individual garments from the production web. The production web is formed by: a) feeding a first elastic web in a travelling direction; b) stretching the first elastic web by 35-250% in the travelling direction; c) intermittently laying down absorbent cores in an intermediate zone extending in a travelling direction of the production web; d) feeding a continuous web of liquid permeable material in the travelling direction and covering the absorbent cores with the continuous web of liquid permeable material; and e) bonding the first elastic web to the continuous web of liquid permeable material in a first lateral zone on a side of the intermediate zone of the production web. In addition, an absorbent garment has a continuous liquid permeable layer.

Description

TECHNICAL FIELD[0001]The invention relates to a method for continuously producing absorbent garments, the method comprising forming a continuous multi-component production web and cutting individual garments from the production web. The invention also concerns an absorbent garment that may be produced according to the method.BACKGROUND ART[0002]Absorbent garments, particularly disposable pant-type absorbent garments include a pant-shaped chassis structure and an absorbent core component permanently integrated with the chassis. A major objective when designing pant garments is to make them resemble ordinary underwear as closely as possible. For this reason, the garment chassis usually comprises a material that is elastically stretchable, at least in the areas intended to be applied over the wearer's hips. In addition, absorbent garments such as pant diapers, sanitary pants and incontinence pants are designed to fit comfortably and snugly about the wearer and it is desired that they h...

Benefits of technology

[0067]In accordance with the invention, the absorbent garment has a reinforcing member which is the continuous inner liquid-permeable surface layer or topsheet. The continuous inner surface layer is preferably a non-elastic material and preferably comprises a layer of nonwoven material. Useful materials include meltspun, meltblown and carded nonwovens. The materials may be thermobonded, hydroentangled, needled, thru-air bonded, or bonded with a bonding agent, as desired. The use of a continuous inner layer in the garment reduces the risk of breaking seams and joins between other components in the garment and of tearing materials that have low tensile strength such as stretch-activated elastic segments when putting on the garment. Moreover, seams and joins bet

Problems solved by technology

A particular problem with pant-type garments is that seams and joins running in a direction parallel to the waist edge of the garment may rupture when the user or a care-giver is pulling on the garment.
