Abstract: A fibrous structure comprising a fibrous matrix with surrogate particles fixed to the fibrous matrix, is provided. Functionally active, fine particles are immobilized on the fixed surrogate particles.

Abstract: A fibrous structure comprising a fibrous matrix with immobilized surrogate particles, is provided. A labile active substance is selectively deposited on the immobilized surrogate particles. In one embodiment, the surrogate particles are porous and have surface cavities, and the labile active substance is deposited in the pores and surface cavities. In another embodiment, the labile active substance is in attractive association with or attached to the surrogate particles.

Abstract: Synthetic fiber safety cutting scissors comprising a pair of first and second elongated scissor blades, each having an inner side and an outer side and a continuous cutting edge, a plurality of non-cutting protrusions part of the blade, and a gripping means; and a means for pivotally securing said first and second scissor blades to each other with said inner sides facing towards each other such that the said cutting edges cooperate with each other to cut strands of synthetic fiber. It has been found that with the protrusions that foreign objects such as fingers may be prevented from being intersected at the cutting edge.
