Abstract
Official abstract text for this publication.
Provided is a cellulose fiber nonwoven fabric with compacted parts that is beautiful even when dry. The cellulose fiber nonwoven fabric is characterized in that: the fabric has compacted parts; the percentage of recesses due to the compacting is 9-25%; the transverse rupture strength is at least 15 N; the transmittance of the compacted parts when dry is 3-25%; and the fabric weight is 30 g/m 2 to 110 g/m 2 .
First claim
Opening claim text (preview).
The invention claimed is: 1. A cellulose fiber nonwoven fabric having compacted parts and non-compacted parts, wherein a percentage of recesses due to compacting is 9 to 25%, a transverse rupture strength of the fabric is at least 15 N, a transmittance of the compacted parts when dry is 3 to 25%, and a basis weight of the fabric is 30 g/m 2 to 110 g/m 2 , a transmittance difference between the compacted parts and the non-compacted parts when dry is at least 2%, and a transmittance difference between the compacted parts and the non-compacted parts when wet is 35% or lower. 2. The cellulose fiber nonwoven fabric of claim 1 , wherein a transmittance of the compacted parts when wet is at least 4%. 3. The cellulose fiber nonwoven fabric of claim 1 , wherein a transmittance of the non-compacted parts when dry is 1 to 4%, and a transmittance of the non-compacted parts when wet is 1 to 30%. 4. The cellulose fiber nonwoven fabric of claim 1 , wherein the cellulose fiber nonwoven fabric does not comprise a binder. 5. The cellulose fiber nonwoven fabric of claim 1 , comprising 50 to 100 parts by weight of cellulose fibers, and 0 to 50 parts by weight of other fibers. 6. The cellulose fiber nonwoven fabric of claim 1 , wherein the compacted parts are formed by heat embossing. 7. The cellulose fiber nonwoven fabric of claim 1 , wherein the texture index of the nonwoven fabric when dry is not greater than 400. 8. The cellulose fiber nonwoven fabric of claim 1 , wherein a percent of the area of the compacted parts in the transverse direction is 2 to 10%.
