  • Publication number: 20110311795
    Abstract: A thermally fusible interlining nonwoven includes a fusing layer (A) having at least one staple fiber nonwoven containing at least 50% by weight of thermoplastic staple fibers having at least one of a melting or softening temperature in a range from 60° C. to 165° C. A layer (B) is bonded together with layer (A) and includes at least one staple fiber nonwoven or a staple fiber nonwoven fabric having staple fibers. At least 80% by weight of the staple fibers of layer (B) have at least one of a softening temperature, melting temperature and degradation temperature that is higher than or equal to 170° C.

  • Patent number: 6802873
    Abstract: The invention relates to a method for producing dyed textile materials consisting of polyester and polyamide. The textile material is dyed by means of pigments or a disperse dye that stains polyester. Surplus dye is removed. The polyamide portion is dyed using vat dyes, leuco vat dyes, sulphide dyes or soluble sulphide dyes. Said dyes are vatted if this is required for obtaining a solubility and are oxidatively converted into the real dyes after attaching.

  • Publication number: 20040194234
    Abstract: The invention relates to a dyed and/or printed non-woven fabric consisting of non-split and/or at least partially split microfibres and/or microfilaments consisting of synthetic polymers containing at least one polyester constituent and at least one polyamide constituent and, optionally, at least one polyurethane constituent, said fabric having been dyed and/or printed by means of at least one azo dye which is produced on the non-woven fabric. The invention also relates to a method for dyeing and/or printing the inventive fabric.

  • Publication number: 20040163189
    Abstract: The invention relates to a method for dyeing and/or printing textile material containing non-split and/or at least partially split micro-fibres and/or micro-filaments, composed of at least one polyamide component and optionally at least one additional polymer component. According to said method, the textile material is treated with formic acid and is dyed and/or printed using at least one dye, selected from the group containing anionic acidic dyes, metal complex dyes, reactive dyes, direct dyes and cationic dyes.

  • Publication number: 20040064898
    Abstract: The invention relates to a method for improving the colour fastness of textile material made of plastics, whereby one or more vat dyes are applied to the textile material which undergoes heat treatment on its own or combined with other dyes/pigments. The material undergoes at least one additional heat treatment in connection with the colour thereof.
