Definitions
- the present invention relates to a process for the manufacture of filaments and fibers having a metallic golden shade from polyesters.
- Filaments and fibers having metallic color shades are known in many variations; however, difficulties often arise during their manufacture, and the color shades often do not meet the requirements.
- This object of the invention is attained by means of filaments and fibers made from high molecular weight synthetic linear polyesters containing of from 0.001 to 0.01% by weight of niobium.
- Such filaments and fibers made from high molecular weight synthetic linear polyesters having a metallic golden shade of excellent quality and of perfect reproducibility can be manufactured as follows: during the normal preparation process for polyesters, niobium pentoxide hydrate having a water content of at least 5%, preferably of from 15 to 25%, is added in an amount yielding a niobium content of preferably from 0.001 to 0.01% by weight in the polyester end product, and their polyester is then processed in known manner by melt spinning to form filaments and fibers.
- polyesters suitable for the manufacture of these filaments and fibers having a metallic golden shade all normal fiber-forming polyesters and copolyesters, especially polyethylene terephthalate, may be employed.
- the niobium pentoxide hydrate having the indicated water content is preferably added to the polyester precondensate. It is also possible to add the niobium pentoxide hydrate during the transesterification or one of the later reaction steps, but this is less advantageous.
- the indicated water content of the niobium pentoxide hydrate is decisive for the obtention of excellent metallic golden shades in the corresponding products.
- This niobium pentoxide hydrate is a finely dispersed, purely white powder, and thus no color pigment.
- the fact that the addition of this purely white substance, and in an extremely small amount too, yields polyester filaments and fibers having such an excellent metallic golden shade, is very surprising.
- niobium pentoxide hydrate is added to other polymers, for example polyamides, polyacrylonitrile and the like, the product is not dyed at all.
- the obtention of a golden shade is specifically linked to ester bonds in the polymer molecule. Therefore, besides pure polyester, for example also polyester amides should be used on principle for the process of the invention, but in these cases, the metallic golden shade is less pronounced than in pure polyesters.
- the niobium pentoxide hydrate has no influence on the preparation process for polyesters. Also the filaments and fibers are normally manufactured by melt spinning; especially in the case of coarse-titer filaments, often even called wires, good results are obtained.
- the technological properties for example strain-stress behaviour, shrinkage, reerection power, tendency to splicing and the like, are unchanged as compared with polyester filaments and fibers manufactured without adding niobium pentoxide hydrate.
- the fastnesses to light, abrasion and washing of the golden shade dyeings are excellent.
- Polyesters having a metallic golden shade are predominantly employed for the manufacture of rot resistant zippers for leather and plastic shaped articles, for example bags, shoes, rainwear and the like.
- Multi-filaments dyed in a golden shade preferably are used for those fashion woven and knitted fabrics, for which, until now, metallic filaments having only a limited corrosion resistance were employed, which latter filaments, when washed, rapidly lose their metallic luster and are only poorly compatible with the textile basic material.
- Dimethyl terephthalate is transesterified with ethylene glycol in the presence of zinc acetate as catalyst and at temperatures of -from 160 to 215 C. 0.0025% by weight of niobium in the form of niobium pentoxide hydrate, dispersed in ethylene glycol, is introduced into the precondensate.
- the niobium pentoxide hydrate is obtained by precipitation with NH OH from niobium pentafluoride, and it is in a finely dispersed, purely white form. After a gentle drying at 120 C. in vacuo, it still contains 20% water of hydration.) Subsequently, the condensation is carried out at temperatures of from 240 to 275 C.
- polyester chips so modified have a goldbrown color. They are spun from an extruder with a temperature program of 275/285/275 C., drawn in a water bath at 98 C., the drawing ratio being 1:5, and
- the filaments have a metallic golden aspect and their ultimate tensile strength is from 3 to 3.5 g./dtex. at elongations at break of from 30 to 35%. Wires having a specific viscosity of more than0.9'display notendency to splicing.
- Filaments and fibers madefrom fiber-forming synthetic linear polyesters of a metallic golden'shade having from 0.001 to 0.01 percent by Weight of niobium.,from incorporated niobium pentoxide and calculated on total weight of polyester and niobium.
- a process for the manufacture of filament and fibers from high molecular weight synthetic linear polyesters having a metallic golden shade wherein, during esterification and polycondensation, or transesterification and polycondensation in the formation of polyesters, niobium pentoxide hydrate, having a water'content from 5 percent to 25 percent, is added in an amount yielding a niobium content of from/0.001 to- 0.01 percent-by weight, from niobium pentoxide, based on total weight of resulting polyester and niobium and the polyester so obtained is then melt spun to form filaments 'and fibers.
