Disposable pant article and method for producing disposable pant articles

A disposable pant article having a waist portion which in use surrounds a user's waist and a crotch portion connecting front and back portions of the waist portion, the crotch portion comprising an absorbent core for absorbing body exudates, a liquid-permeable topsheet which in use faces a user's crotch, and a liquid-impermeable backsheet which in use faces the user's clothing, the topsheet covering the absorbent core;

• wherein the article has an inside surface consisting of inside surface portions which in use faces the user's skin and an outside surface consisting of outside surface portions which is opposite the inside surface and in use faces the user's clothing;
• wherein the inside and outside surface portions of the article are each composed of a plurality of fabrics which define the colours of the inside and outside surface portions, respectively, of the article, the liquid-permeable topsheet and the liquid-impermeable backsheet each being one of the fabrics;
• wherein the plurality of fabrics of the outside portions have, in the CIE L*a*b* colour space, L* values less than 80 and mutual colour differences ΔE*ab less than a predetermined limit;
• wherein the plurality of fabrics of the inside portions have, in the CIE L*a*b* colour space, an L* value less than 90 and mutual colour difference ΔE*ab more than said predetermined limit;
• and
• wherein the absorbent core or upper layer thereof has an L* value of more than 90.

A method for manufacturing a plurality of disposable pant articles, wherein each article comprises a waist portion which in use surrounds a user's waist and a crotch portion connecting front and back portions of the waist portion, the crotch portion comprising an absorbent core for absorbing body exudates, a liquid-permeable topsheet which in use faces a user's crotch, the topsheet covering the absorbent core, and a liquid-impermeable backsheet which in use faces the user's clothing, wherein each of the articles has an inside surface and an outside surface, the method comprising the steps of:

• composing each of the inside surfaces and the outside surfaces of the articles from a plurality of fabrics which define the colours of inside and outside surfaces of the articles, the liquid-permeable topsheet and the liquid-impermeable backsheet each being made from one of said fabrics, the fabrics having colours which are chosen such that:
• at least the plurality of fabrics of the outside surfaces of all of said plurality of articles have, in the CIE L*a*b* colour space, L* values less than 80 and mutual colour differences ΔE*ab less than 10;
• for all of said plurality of articles, a surrounding zone of the inside surface, which is a part on the topsheet which at least partly surrounds an absorption zone where the absorbent core is located underneath, also has an L* value less than 80 and a mutual colour difference ΔE*ab less than 10 with the outside surface of the respective article;
• for all of said plurality of articles, the absorbent core or upper layer thereof has an L* value of more than 90;
• and
• for all of said plurality of articles, the absorbent core or upper layer thereof is visible through the topsheet such that the absorption zone has, as a result of the combination of colours of the absorbent core and the topsheet, an L* value less than 90 and a colour difference ΔE*ab more than 5 with respect to the surrounding zone or the outside surface of the respective article.
