Definitions

  • the present invention relates to a method of partially swelling a polyamide fibre, wherein a core region of the fibre remains essentially un-swollen and the surface structure of the fibre is swollen.
  • the invention further relates to a polyamide fibre, comprising a core region and a swollen surface structure. Finally, the invention relates to different uses of such fibres.
  • polyamide fibres in textiles are well known in the art.
  • polyamide fibres are produced by a melt spinning process and exhibit high strength, abrasion resistance and dimensional stability.
  • Textile applications of polyamide fibres include clothing but also technical and heavy duty textiles as well as usage in reinforcing fibres in polymer fibre composites.
  • polyamide fibres show smooth surfaces with low surface energy and high chemical inertness due to the fibre manufacturing technologies. This feature, however, makes the use of polyamide fibres unsuitable for applications requiring better adhesion to other substances, for example polymer matrices in polymer fibre composites or higher sorption capability of fibres.
  • the general purpose of surface modification of fibres is to alter the physical, chemical or biological properties of the native surface.
  • Surface engineering is the discipline that addresses the modification of surfaces especially of solid materials. There is big interest on the modification of the surface without affecting the bulk properties. Characteristics like hydrophobicity, adhesion, hardness, permeability, friction factor, bacterial repellence, surface conductivity, and biocompatibility can be modified. Other properties like dyeability, wettability and biocompatibility can also be changed by varying the properties and the structure of the surface. Another aspect could be the formation of a hydrophobic fibre coating or introduction of a micro-structure onto the surface to implement hydrophilicity to the fibre. There are different methods by which the modification of the surface of polyamide fibres can be accomplished. There has already been some research on plasma modification, heat treatment, chlorosulfonation, polymerization etc. to change the amount of endgroups at the surface.
  • This object is solved by a method of swelling the surface of a polyamide fibre, wherein the polyamide fibre is exposed to a mixture comprising calcium chloride, ethanol and water, wherein the calcium chloride content is > 6 mol%, the ethanol content is ⁇ 25 mol% and the molar ratio (moles / moles) between water and ethanol is > 2.5.
  • the fibre is exposed to the mixture by soaking or padding.
  • Preferable suitable solvents for achieving the novel fibre structure is comprising of 8 mol% to 20 mol% calcium chloride, 9 mol% to 21 mol% ethanol and the ratio between water and ethanol content is above 2.5 whereas the sum of all three components make 100 mol%.
  • Fibres were placed onto an object slide and treated by covering the fibres with the solution. It was covered with another object slide to prevent the evaporation of ethanol. With a magnification of 10, pictures were taken under the light microscope and the fibre diameters were determined up to a treatment time of 50 minutes.
  • the water vapour adsorption was measured gravimetrically with an automated multisampling moisture sorption analyzer SPS11 (ProUmid, Ulm, Germany) at 25 °C.
  • the samples were conditioned at 25 °C and 40% relative humidity (RH). Then the relative humidity was reduced to 0% and the sorption and desorption cycles were started.
  • the steps for the increase and decrease in RH were 10%, from 0 to 95% RH.
  • the mass of the sample was measured every 10 min and the equilibrium condition was set to a mass change of 0.003 % per 60 min. Once the equilibrium was reached the RH was increased/decreased to the next step.
  • the minimum time was 120 min and the maximum time 48 h for one cycle. Five samples were measured.
  • the untreated fibres as a reference, fibres treated with solution CE-17 for 10 min and 15 min and fibres treated with solution E-2 for 10 min and 15 min.
  • the treated fibres were dyed in a dyeing solution of DR81 (Direct Red 81 from Sigma Aldrich).
  • the dyeing solution was prepared by weighing 100 mg of DR81 and then filling it up to 11 with water. The solution was put in a water bath with 80 °C for 30 min. Afterwards a serial dilution of the main solution was made to get the concentrations of 20, 40, 60, 80 and 100 mg/l dye in water. For every concentration a double determination was performed. The ratio of sample to dyeing solution was 1:100.
  • the treated samples were dyed at 80 °C for 1 hour. After dyeing, the samples were washed 3 times with cold water. The remaining solution was allowed to cool down to do the photometry measurements afterwards.
  • the Photometry was conducted on a Analytik Jena Specord Spectrophotometer.
