摘要:
Disclosed is a highly adhesive polyester film having a highly adhesive primer layer disposed on at least one side of a substrate polyester film. The substrate polyester film is a stretched film having linear tearability and formed of a mixed polyester resin containing polyethylene terephthalate and a modified polybutylene terephthalate, and the highly adhesive primer layer contains a polyester resin (A) having an acid number of 20 to 60 mg KOH/g and a hydroxyl number of 30 to 150 mg KOH/g, and having an oligomer content of 2.0% by mass or less, and substantially contains no crosslinking agent component.

PROBLEM TO BE SOLVED: To provide a method for manufacturing, by means of a melt extrusion, biaxial-oriented polyester film which has high surface roughness, satisfactory diffusion effect, and high adhesiveness.SOLUTION: The method for manufacturing the polyester film comprises steps of: providing at least one polyester material and adding diffusion particles to the at least one polyester material; melt extruding and then rapidly cooling the polyester material to form a polyester plastic sheet; and biaxially stretching the polyester plastic sheet followed by cooling to thereby obtain the relevant polyester film.
摘要:
An adsorption filter material (I), preferably for the production of protective materials, preferably NBC (nuclear, biological, chemical) suits, comprises: (a) a first layer; (b) an adsorption layer comprising a first activated carbon layer with particulate and/or spherical activated carbon with additionally activated carbon fibers and a second activated carbon layer comprising activated carbon fibers and; (c) a second layer. Independent claims are included for: (1) protective material, preferably suits, gloves and coverings comprising the filter material (I) and; (2) a process for improving the break-through properties of an adsorption filter material (I) by forming the adsorption layer (B) of a combination of particulate and fibrous particles or by having separate layer of particles and fibers.

PROBLEM TO BE SOLVED: To provide an adsorption filter material or a surface filter material suitable for producing every kind of protective material such as a protective clothing, an NBC protective clothing in particular, protective gloves, protective cover, and for other filtering use, e.g., an air filter or medical use, or surface filter material, i.e., flat type filter material. SOLUTION: This adsorption filter material 1 is used for producing all kinds of protective adsorption materials, and is provided with a first layer 2, a second layer 3 and an adsorption layer 4 disposed between the first and second layers 2, 3. The adsorption layer 4 has a first activated carbon layer 5 having granular and/or spherical activated carbon. The first activated carbon layer 5 further contains activated carbon of activated carbon fiber form. The adsorption layer 4 contains a second activated carbon layer 6 having activated carbon of activated carbon fiber form. COPYRIGHT: (C)2005,JPO&NCIPI
