Provided is papermaking fibers containing two kinds of compounds, a specific alkalized fibrous carboxyalkyl cellulose and a specific carboxyalkyl cellulose salt. That is a water-dispersible sheet comprising a papermaking fiber and an alkalized fibrous carboxyalkyl cellulose and further comprising a carboxyalkyl cellulose salt, wherein the degree of etherification of the fibrous carboxyalkyl cellulose is 0.2 to 0.6, the degree of etherification of the carboxyalkyl cellulose salt is 0.5 to 1.6, the viscosity of 1% aqueous solution of the carboxyalkyl cellulose salt measured by Brookfield viscometer is 2 to 200 mPa-s, and the ratio of the carboxyalkyl cellulose salt to the sum of the papermaking fibers and the alkalized fibrous carboxyalkyl cellulose is 0.1 to 10% by weight.

摘要： In order to increase the security of value or security documents 100, a multi-luminescent security element 400 is provided which contains at least one first luminescence means 510 and at least one second luminescence means 520. The first luminescence means 510 can be excited under first excitation conditions Sp-1 for the purpose of luminescence, and the second luminescence means 520 can be excited under second excitation conditions Sp-2 for the purpose of luminescence, said second excitation conditions Sp-2 differing from the first excitation conditions Sp-1. The multi-luminescent security element 400 is additionally equipped with at least one absorber means 600 which prevents an excitation of the at least one first luminescence means 510 under the second excitation conditions Sp-2 for the purpose of luminescence.

摘要： An airlaid substrate includes at least one bicomponent fiber having a first region and a second region. The first region includes polypropylene and the second includes a blend of an ethylene-base polymer and an ethylene acid copolymer. The ethylene-base polymer has a density from 0.920 g/cm3 to 0.970 g/cm3 and a melt index (I2) from 0.5 g/10 min to 150 g/10 min. The ethylene acid copolymer includes the polymerized reaction product of from 60 wt % to 99 wt % ethylene monomer and from 1 wt % to 40 wt % unsaturated dicarboxylic acid comonomer, based on the total weight of the monomers in the ethylene acid copolymer. The ethylene acid copolymer having a melt index (I2) from 0.5 g/10 min to 500 g/10 min.

摘要： A nonwoven web, containing at least one first homogeneous layer consisting of a blend of at least one of defibrated natural plant based fibers, individualized natural plant based fibers and staple fibers is provided. The nonwoven web contains no binder, adhesive or thermal bonding fibers and a basis weight of the at least one homogeneous layer is from 20 g/m2 to 100 g/m2. When a weighted average fiber length of the blend is greater than about 4.0 mm, the nonwoven web is a non-dispersible product which does not meet the requirement for dispersibility in accordance with INDA/EDANA GD4, and when a weighted average fiber length of the blend is less than about 4.0 mm, the nonwoven web is a dispersible product as defined in accordance with INDA/EDANA GD4. Methods to prepare the nonwoven web are provided.

摘要： A composition obtained by combining virgin cellulose fibers, cellulose ester (CE) staple fibers having a denier per filament (DPF) of less than 3, and water, and water. The CE staple fibers can also have a short cut length of less than 6 mm and can be crimped. The compositions, when co-refined, are useful to make wet laid products such as paper, cardboard, and filters that have improved water drainage, air permeability, tensile strength, bulk, burst strength, or stiffness, or a combination of these properties.
