Abstract: The object of the invention is a strengthened fibre fleece from staple fibres containing as strengthening agent a copolymer based on acrylic and/or methacrylic acid esters and styrene. The copolymer contains additionally in copolymerised form a monomer having nonconjugated carbon double bonds, acrylic acid and methacrylic acid, and methacrylamido-N-methylolmethylether. In a process for producing the strengthened fibre fleece, the fibre fleece is impregnated with an aqueous dispersion of the copolymers and subsequently dried at temperatures between 60* and 130*C.
Abstract translation: 本发明的目的是从含有作为强化剂的基于丙烯酸和/或甲基丙烯酸酯和苯乙烯的共聚物的短纤维增强的纤维绒。 该共聚物另外含有共轭形式，具有非共轭碳双键的单体，丙烯酸和甲基丙烯酸，以及甲基丙烯酰胺基-N-羟甲基甲基醚。 在生产强化纤维羊毛的方法中，将纤维羊毛浸渍在共聚物的水性分散体中，随后在60℃至130℃的温度下干燥。

Abstract: A high bulk bonded non-woven fibre fleece containing natural and/or synthetic fibres and binder fibres, which are adhesive at higher temperatures, said binder fibres consisting of a saponified ethylene-vinyl acetate copolymer, the molar ratio of vinyl acetate to ethylene in said copolymer before saponification being in the range of 1:1 to 1:20. In the process to produce the bonded fleece, the fibres containing 5 to 50 percent by weight of binder fibres are formed to a non-woven fleece and the formed fleece is heated to temperatures of above 110* C, to render adhesive the binder fibres.

Abstract: An aqueous dispersion of copolymers are used as binders for the production of optionally dry-cleanable nonwoven materials. The copolymers consist of copolymerized units of 1 - 2.5% by weight of N-methylol(meth)acrylamide, 1 - 2.5% by weight of (meth)acrylamide, 0.5 - 3% by weight of alpha , beta -monoolefinically unsaturated di- or tricarboxylic acids with 4 to 6 carbon atoms and 89.5 - 97.5% by weight of (meth)-acrylic acid esters having 1 - 18 carbon atoms in the alcohol component.

Abstract: A process for identifying manufactured articles in which a marking agent such as a homo- or copolymer of polymerizable ethylenically unsatured monomers is applied to the articles. Said homo- or copolymer contains at least one group which can be split off to form a low molecular weight compound such as an amine or phenol, which can be converted into dyes, said dyes being used to identify the manufactured articles.
