Document Type and Number:
WIPO Patent Application WO/2018/216047
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a sheet material for infusion, a filter for infusion, and a bag for infusion having superior transparency and component infusion properties, not easily leaking powder, and having adequate mechanical properties with a high modulus. Provided is a sheet material for infusion having a first layer of spunbond nonwoven fabric with an 8 – 19 g/m2 mesh formed from polyester based fiber with an average fiber diameter of 18 – 28 µm and has a second layer of melt flow nonwoven fabric with a 2 – 8 g/m2 mesh formed from polyester based fibers with an average fiber diameter of 16 – 28 µm, wherein the total of the length of all fibers included in 1 cm2 thereof is 3.3 – 4.8 m, with the 3% modulus being 5.5 N or greater. Also provided are a filter for infusion and a bag for infusion formed from this sheet material for infusion.
