The present invention provides a process for preparing a pre-treated low Dk-type glass fabric for constituting a circuit board, comprising pre-treating low Dk-type glass fabric with a pre-treating varnish having a Dk close to the Dk of the used low Dk-type glass fabric at different temperatures and having a small Df. The present invention further provides a bonding sheet and a circuit board prepared thereby. The circuit boards prepared by the preparation process of the present invention have a Dk having small differences in warp and weft directions, and can effectively solve the problem of signal propagation delay. The circuit boards have a small Df, so as to have a small signal loss. Meanwhile, the cured, partially-cured or uncured dry glue obtained after drying the solvent of the pre-treating varnish has similar dielectric properties at different temperatures to the used low Dk-type glass fabric, so that the circuit boards have a very small signal propagation delay at different temperatures.

A method for making a fiber containing active ingredients from a Chinese herb. The method includes subjecting a fiber material, which is to be combined with active ingredients from the Chinese herb, to be swelled with a solvent of cellulose and then to be impregnated in a solution of an extract of the Chinese herb. The fiber material is a cellulose fiber or a spunlaced nonwoven fabric made thereof. The method requires no use of adhesives. With the method, the fiber material does not need to be subjected to acidic or basic solutions or high temperature, which would cause the active ingredients to be decomposed. The method can provide a cellulose fiber or a nonwoven fabric made thereof, both of which have a higher content of active ingredients from a Chinese herb and higher durability. Furthermore, the method is simple and is easy to control, and thus, suitable for mass production.
