There is provided a sheet for food extraction using no chemical such as a
chemical binder or a paper-making aid, using an adhesive composite fiber
as a raw material, exerting no influence on the global environment, being
excellent in safety to the human body and sanitation, and satisfying
performance such as bag-making processability, heat stability, uniformity
in texture, extraction properties and prevention of powder leakage, by an
air-laid sheet for food extraction produced by preparing a fiber web (1),
by an air-laid process, which mainly comprises a heat-adhesive composite
fiber (A) having a fineness of 1.0 to 4.5 dt wherein a sheath component
as a low-melting component of a sheath-core type composite fiber or a
low-melting component of a side-by-side type composite fiber has a
melting point of 110 to 170.degree. C., and performing interfiber bonding
by heating to achieve integration.
