A composite fiber may include at least one reinforcing filament formed of a first material. A second material maybe systematically deposited in a printed onto the at least one reinforcing filament such that at least one of a length, a width, and a thickness of the second material varies across a surface of the at least one reinforcing filament. The printed pattern may alter one or more properties of a composite structure containing the composite fiber.

The invention discloses a fiber filament non-woven fabric with a small pore size and a large porosity, which adopts an island type ultra-fine fiber single filament, which is juxtaposed into an unidirectional silk layer several times, and a thin strip-shaped liquid is applied laterally on the unidirectional silk layer. The resin adhesive liquid bonds and fixes all the silk layers into a unidirectional non-woven fabric fixed in a grid segment. The unidirectional non-woven fabric is covered with meltblown non-woven fabric on one or both sides to make a filter material that can 100% filter viruses, bacteria, and micro-particles smaller than PM2.5. It can also be used for a wider range of filter materials, thermal insulation materials, oil absorption materials, battery separator materials, medical and health materials, environmental protection materials, clothing materials, wiping materials.

An environmentally friendly, aqueous binder composition that includes a metal salt and a polyol is provided. The metal salt may be a water soluble salt, including salts of boron, aluminum, gallium, indium, tin, zirconium, thallium, lead, and bismuth. The polyol may include water miscible or water soluble polymeric alcohols including polyvinyl alcohol. The binder composition may be used in the formation of insulation materials and non-woven mats, among other products.

A partially separated fiber bundle includes a separated fiber section and an unseparated fiber section, being configured to give a ratio A.sub.max/A.sub.min of 1.1 or larger and 3 or smaller, when the number of fiber bundles contained in the width direction of the partially separated fiber bundle (fiber separating number: N.sub.n) measured at a freely selected point P.sub.n (where, n represents an integer of 1 to 100, and freely selected points P.sub.n and P.sub.n+1, excluding n=100, being 50 cm or more away from each other), is divided by a full width of W.sub.n of the partially separated fiber bundle, to calculate the fiber separating number per unit width A.sub.n, and assuming its maximum value as A.sub.max and its minimum value as A.sub.min.
