摘要:
The present invention relates to polyurethane ureas dissolved in organic solvents, which may be used as an adhesive coat for the coating of textiles.
摘要:
The invention relates to a method for coating sheet-form textile materials, in which there is applied to a sheet-form textile material an aqueous dispersion containing anionically modified polyurethane ureas comprising (A) aromatic diisocyanate, (B) polyether polyol having a mean molecular weight greater than 1500, (C) at least one compound containing from 1 to 2 isocyanate-reactive groups and at least one ionogenic group, (D) polyamine having a mean molecular weight of at least 32, and (E) water, wherein the mean total functionality of the isocyanate-reactive compounds B to D is from 1.85 to 2.2, the molar ratio of the isocyanate groups of component A to the isocyanate-reactive groups of components B to D is greater than 1, and the polyurethane ureas have a content of from 800 to 1500 mmol of urethane groups/kg of anionically modified polyurethane urea and a content of from 800 to 1800 mmol of urethane plus urea groups/kg of anionically modified polyurethane urea.

摘要:
In the method of inputting information in an electrical unit, after input of an alphabetic character the character itself, or, for the case in which one or more characters have been input prior to the input of the alphabetic character, the character string formed by the first to the last input character is compared with information entries in a comparison set of information, and, when the input character is the same as the first character of one of the information entries in the comparison set or when the character string agrees with the beginning of one of the information entries in the comparison set, this information entry is offered for input to the electrical unit. The information entry offered for input is preferably displayed with all its characters on a display device prior to input. The offered information entry can then be rejected by the operator of the electrical unit by inputting another alphabetic character immediately following input of the alphabetic character. Alternatively, the offered information entry can be input by the operator.
