Definitions

  • Shaped bodies in particular fibers and their fabrics, with thermoregulatory properties
  • the invention relates to moldings having improved thermoregulatory properties, composed of network-forming polymers and phase change materials incorporated therein, which can be processed as fibers into textile fabrics having heat-storing and heat-giving properties and which give improved textiles improved comfort, as well as in other applications have a high level of functionality in terms of heat storage and disposal.
  • phase change materials can absorb or release relatively large amounts of heat as their phase state or conformation changes at a constant temperature.
  • an increased heat capacity is found, which finds its physically measurable expression in the enthalpy of fusion occurring and allows the storage or release of larger amounts of heat than the normal heat capacity of the material outside the temperature range of the phase transition or the conformational change would correspond.
  • phase change material paraffins or salts or solutions of suitable salts can be used.
  • the temperature range of the phase transition from the solid to the molten state can be adjusted in a targeted manner to the respective required temperature at which the heat is to be released or stored by varying the chain length.
  • Salts or their solutions can be selected specifically according to the desired temperature range of the conformational change.
  • the microencapsulated form is particularly suitable.
  • phase change material is enclosed in ceramic or polymer spheres with diameters in the ⁇ m range and thus brought into a manageable form which allows inclusion in crosslinked polymeric matrix materials, wherein the efficiency of the thermoregulation of the type and amount of the enclosed PCM Material is dependent.
  • US 5,885,475 describes apparel composed of fibers consisting of a polymer blend additionally containing phase change material.
  • the fiber-forming substances are made selected from the group of synthetic melt-spinnable thermoplastic polymers.
  • Multicomponent fibers with increased, reversible thermal properties and textile fabrics produced therefrom are described in WO 03027365, US 200212079 and US 200129648.
  • the fiber bodies consisting of a multiplicity of elongated components, contain at least in one of these stretched components a temperature-regulating material distributed therein.
  • This may be a phase change material and optionally the classes of hydrocarbons, hydrated salts, waxes, oils, water, fatty acids, fatty acid esters, 2-basic acids and esters, halides, clusters and semiclusters, gas clusters, stearin anhydrite, ethylene carbonate, higher alcohols, polymers and metals and mixtures thereof.
  • the arrangement of the various components of the fiber can optionally take place in a core-sheath structure, polysetational, bundled or strip-shaped at different shaped cross-section.
  • the matrix material of the described multicomponent fiber can consist of different, linear chain molecules.
  • a disadvantage of these fibers and textile fabrics made therefrom is that only a portion of the fibers formed therefrom contain phase change material as a result of the described arrangement of the individual components and the proportion of temperature-regulating material in the overall fiber is naturally limited. Due to the presence of multicomponent structures of a plurality of elongated constituents, the proportion of phase change material that can be introduced into the polymer structure is limited to a proportion of at most 50 percent by mass, based on the respective matrix material.
  • WO 02095314 and CH 0200245 likewise describe processes in which the temperature-regulating properties are to be achieved by printing on a textile fabric with microencapsulated phase change material. The temperature-regulating effect is thus achieved by applying a coating containing phase change material.
  • phase change material can be fixed on the surface of the structures, in particular if only a part of the surface is printed with a suspension of microencapsulated phase change materials and thus the temperature regulating effect, based on the Amount of material, comparatively localized.
  • the printing of a textile surface with a suspension of microencapsulated phase materials applied in a comparatively large layer thickness has a disadvantageous effect on the flexibility of textile products made therefrom and thus also on the wearing properties.
  • suspensions of microencapsulated phase change materials applied to textile surfaces have only limited mechanical resistance and are washable.
  • PCM fibers described so far are manufactured on the basis of synthetic polymer fibers.
  • matrix materials such as cellulose and / or globular proteins are not mentioned as a polymer matrix.
  • network-forming structures can be prepared, for example, from cellulosic molding and spinning compositions by dissolving cellulose in tertiary amine oxides, preferably N-methylmorpholine-N-oxide, and a non-solvent, preferably water.
  • a spinning solution of cellulose in N-methylmorpholine-N-oxide and water is deformed by a dry-wet spinning process, coagulated in, for example, an aqueous spinning bath, the solvent completely removed by washing several times and the solidified shaped bodies dried.
  • the shaped bodies thus obtained then have a network structure characterized by hydrogen bonds.
  • the globular proteins have, as the name implies, a spherical tertiary structure and occur in nature in relatively frequent numbers. Examples are the casein (milk protein), the zein (corn protein) and the ardenin (peanut protein).
  • the object of the invention is to develop moldings having improved thermoregulatory properties which contain an increased proportion of introduced phase change material compared to fibers produced on a synthetic basis and thus should have an increased thermo-regulating potential while avoiding the cited disadvantages of the prior art.
  • attention should be paid to the use of naturally occurring raw materials and, in as few process steps as possible, environmentally friendly fibers with the described properties should be produced by using natural resources.
  • the object is achieved by introducing phase change materials up to a content of 200% by mass into network-forming polymers, the network being formed by the chemical coupling of functional groups, hydrogen bonds or helically interconnected polymeric or oligomeric structures.
  • a suitable network-forming polymeric matrix material is native cellulose. This forms bonds which on the one hand cause cross-linking of the polymer structure and on the other hand cause the formation of a superstructure by the formation of hydrogen bonding. By this structure formation, the embedding of even larger amounts of microencapsulated phase change materials is possible. The microencapsulation causes the demarcation between the phase change material and the polymer matrix.
  • phase change material for example, example, paraffins of different chain length application, wherein the temperature of the phase transition depends on the chain length of the molecules and can be adjusted by changing the chain lengths the required temperature range of the phase transition.
  • inorganic hydrated salts are applicable, which can be selected depending on the desired temperature range of the conformational change. Due to their higher density compared to paraffins, it is possible in particular to introduce far more than 50% by mass of phase change material into the polymer matrix.
  • globular proteins which are numerous and naturally obtainable in nature. Starting from a primary structure based on peptide bonds, a secondary structure in the form of folds of the amino acid chain, which is based on hydrogen bonding, forms a spatially cross-linked tertiary structure, which is stabilized, for example, by disulfide bonds, hydrogen bonds, or ionic or hydrophobic interactions.
  • precrosslinked globular proteins are likewise soluble in tertiary amine oxides and can be shaped by a dry-wet process.
  • the solution of the precrosslinked globular protein can be added as a further constituent of a polysaccharide such as cellulose. This gives the possibility of being able to influence the properties of the moldings in a targeted manner.
  • a cellulose solution in a water-containing tertiary amine oxide phase change materials up to a content of 200 Percent mass, based on the mass of the cellulose containing added and this solution over an air gap warped and then precipitated the cellulose with the trapped phase change material in a precipitation bath, for example from water or a water / alcohol mixture to form physical networks.
  • a precipitation bath for example from water or a water / alcohol mixture to form physical networks.
  • crosslinking of the polymeric matrix results in complete and mechanically stable entrapment of the microencapsulated phase change materials coupled with optimum heat transfer to or away from the phase change material.
  • precrosslinked globular proteins in N-methylmorpholine-N-oxide optionally with the addition of polysaccharides such as cellulose, are converted into a spinning solution and spun into filaments by known processes.
