Definitions

  • alkyl glycosides as textile additives
  • the invention relates to the use of special alkyl glycosides as surfactants in the textile pretreatment of textile fabrics, yarns or flakes.
  • the aim of the textile pretreatment is to remove the accompanying substances of the textile fabrics, yarns or flakes as easily and gently as possible, which disrupt the finishing processes, such as dyeing, printing, optical brightening or finishing.
  • the pretreated goods must not contain any disruptive amounts of dirt, preparations, sizes and natural fibers.
  • the goods must have a sufficiently high degree of whiteness and show uniform and high dye absorption and absorbency.
  • Synthetic textile fabrics or yarns generally contain spin finishes, size and dirt which are to be removed by washing processes. Natural textile fabrics and yarns are much more difficult to separate from the disruptive accompanying substances such as size, preparations, waxes, pectins etc.
  • the primary purpose is alkaline boiling.
  • Desizing and bleaching are suitable as pretreatment processes for synthetic and / or natural fibers, but are mostly chosen alone or in combination with alkaline decoction for natural fibers.
  • the textile goods are first brought into contact with a chemical-containing liquor that contains surfactants.
  • surfactants have the task of permitting wetting and penetration of the textiles and removing size, preparations, dirt of all kinds and fiber accompanying substances from the textile material.
  • Such surfactants must be alkali-stable and temperature-resistant, compatible with other finishing chemicals, such as oxidizing agents, in bleaching and desizing, and have a high affinity for fibers to deaerate textile materials.
  • the tensides should be subject to environmental contracts, that is to say they should be biodegraded well, and should not have any toxic effects on aquatic organisms.
  • alkyl glycosides Because of their biological compatibility and their known wetting properties, alkyl glycosides have recently been used increasingly in household detergents and cleaning agents. Household detergents containing alkyl glycosides in combination with at least one customary anionic surfactant are described in European patent application EP 70 074. Furthermore, liquid detergents are known from European patent application EP 105 556, which contain alkyglycosides, certain other nonionic surfactants and anionic surfactants. From international patent application WO 86/2943, alkyl detergent-containing liquid detergents are known which contain conventional anionic surfactants.
  • surfactants for textile pretreatment are subject to significantly higher requirements than household detergents.
  • surfactants for textile pretreatment need a larger chemical Show kali and temperature resistance and also solve more and above all other disruptive accompanying substances of the textile fabrics, yarns and flakes as dirt such as size, preparations, pectins etc. in a shorter time.
  • the detergent concentrates used in dilute form show in commercial operations at water hardness of 0 ° dH for household-typical soiling of the type dust-wool fat, blood, milk cocoa, dust-house fat
