摘要:
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° C., and performing interfiber bonding by heating to achieve integration.
