Abstract

Provided is a nonwoven fabric for skin care products. The nonwoven fabric includes: a thermoplastic resin fiber having a single fiber diameter of 50 nm or more and 800 nm or less; and a cellulose fiber having a tensile strength measured in accordance with JIS L 1015:2010 8.7.2 of 1.9 cN/dtex or less. A total content of the thermoplastic resin fiber and the cellulose fiber is 85% by mass or more relative to a total mass of the nonwoven fabric for skin care products, and a content ratio by mass of the thermoplastic resin fiber and the cellulose fiber (Thermoplastic resin fiber/Cellulose fiber) is 0.06 to 0.22.

Claims

exact text as granted — not AI-modified
1 . A nonwoven fabric for skin care products, the nonwoven fabric comprising:
 a thermoplastic resin fiber having a single fiber diameter of 50 nm or more and 800 nm or less; and   a cellulose fiber having a tensile strength measured in accordance with JIS L 1015:2010 8.7.2 of 1.9 cN/dtex or less, wherein   a total content of the thermoplastic resin fiber and the cellulose fiber is 85% by mass or more relative to a total mass of the nonwoven fabric for skin care products, and a content ratio by mass of the thermoplastic resin fiber and the cellulose fiber (Thermoplastic resin fiber/Cellulose fiber) is 0.06 to 0.22.   
     
     
         2 . The nonwoven fabric for skin care products according to  claim 1 , wherein the thermoplastic resin fiber is a polyamide fiber. 
     
     
         3 . The nonwoven fabric for skin care products according to  claim 1 , wherein the cellulose fiber is rayon. 
     
     
         4 . The nonwoven fabric for skin care products according to  claim 1 , wherein a fiber length of the cellulose fiber is 35 mm or more. 
     
     
         5 . A face mask comprising the nonwoven fabric for skin care products according to  claim 1 . 
     
     
         6 . A cleansing sheet comprising the nonwoven fabric for skin care products according to  claim 1 .
