摘要:
Vividly colored absorbent articles useful as wiping articles and a method for their manufacture. A preferred article is characterized by (a) a nonwoven web comprised of organic fibers having a plurality of pendant hydroxyl groups; (b) a binder comprising a cross-linked polyvinyl alcohol and a hydrophobic polymer coated on at least a portion of the fibers, (c) pigment distributed within the binder.
摘要:
A plasma treatment process in two steps is disclosed for antiballistic materials, such as aromatic polyamides. In the first step, a plasma treatment is applied with at least 50 % inorganic gas or a mixture of inorganic gasses and in the second step a plasma treatment is applied with a water-proofing organic gas or with mixtures of such gasses from the group of the saturated hydrocarbons, unsaturated hydrocarbons, saturated fluorohydrocarbons, unsaturated fluorohydrocarbons, siloxanes or vinyl compounds. In the second step a mixture of one or several inorganic gasses with one or several water-proofing organic gasses may also be used. This process improves the antiballistic properties.
摘要:
The present invention provides a fiber that can exhibit both excellent antistatic properties and high water repellency, and a high bulk nonwoven fabric with a good texture that exhibits high water repellency. More specifically, the present invention is a highly water repellent fiber that is a conjugate fiber having a plurality of thermoplastic resins as the primary component thereof and having a fiber treatment agent comprising at least Component (A) and Component (B) below deposited thereon at 0.1 to 1.0 wt% in relation to the weight of the fiber, with Component (A) accounting for 75 to 97 wt% and Component (B) accounting for 25 to 3 wt% of the fiber treatment agent: Component (A): polysiloxane Component (B): alkane sulfonate metal salt.
摘要:
Disclosed are fibers that are capable of spontaneously transporting certain fluids, for example aqueous fluids, such as water, on their surfaces. The fibers, especially in the form of tow, can be incorporated into absorbant articles, such as diapers, in order to transport fluids to more effectively utilize the absorbant portion of the article.

摘要:
A method for the recovery of a metal from a liquid medium containing the metal I solution or in finely divided insoluble from comprises contacting the medium with a functionalised polymer fibre capable of binding the metal and recovering the metal from the fibre. The polymer fibre is suitably a polyolefin, a fluorinated polyethylene, cellulose or viscose, which is functionalised by the radiation grafting of at least one monomer. The method is particularly suitable for the recovery of platinum group metals from process residues.
摘要:
A process which can yield a crosslinked acrylic hygroscopic fiber having sufficient performance with respect to moisture absorption/release and in which the amounts of chemicals (hydrazine, sodium carbonate, etc.) used for crosslinking and hydrolysis can be reduced and the time required for these treatments can be shortened. The process comprises crosslinking and hydrolyzing an acrylic fiber made of a polymer containing 1 to 5 wt.% comonomer units having an acid group.
