Definitions

  • the present invention relates to a plant fatty acid-containing synthetic fiber and a method for manufacturing the same. More particularly, the present invention relates to a plant fatty acid-containing synthetic fiber which exhibits excellent physical properties including strength and elongation and is significantly improved in appearance and anti-staticity, and a method for manufacturing the same.
  • Synthetic fibers including polyester fibers are widely used as materials for clothes thanks to their excellent strength, elongation and durability.
  • synthetic fibers are disadvantageous in that they are stiff, give a feeling of repulsion upon contact with the skin, and give rise to significant static electricity.
  • Korean Patent Nos. 10-0726409 and 10-0515808 which describe the direct coating and fixation of synthetic fibers with plant extracts.
  • the synthetic fibers coated with plant extracts do not persistently exhibit antibacterial activity because the extracts bleed out of the fibers upon washing.
  • a method of microencapsulation of plant extracts in which the plant extracts are trapped inside microcapsules and the microcapsules are attached to the surface of the fibers was suggested as a solution to the problem. This method was however problematic in that the microcapsules readily separate from the fibers under the conditions of friction, washing, light exposure and the like.
  • Melt spinning may be contemplated as a method for manufacturing plant extract-containing fibers.
  • typical melting points for synthetic fibers are on the order of 200 ⁇ 300°C at which plant extracts or vegetable oils, if used in advance of melt spinning, may undergo evaporation, degradation and/or denaturation and thus cannot be incorporated into fibers or will not exhibit sufficient functionality even if incorporated.
  • Korean Patent No. 10-0910241 teaches an electrospinning method by which fine fibers can be drawn at low temperatures from a solution of (a) at least one component selected from among plant extracts and vegetable essential oils and (b) at least one fiber-formable polymer in (c) a solvent.
  • a solution is erupted from a nozzle by the electrical force formed between a collector and the nozzle and becomes a jet stream which is then dried into nanofibers as the solvent evaporates when it reaches an incomplete region.
  • Electrospinning is considered to be a solution to most of the problems associated with conventional spinning methods.
  • electrospun fibers exhibit poor mechanical properties because they are not accompanied by the strength enhancement imparted by the molecular orientation of the polymer. For this reason, electrospun fibers are not used for clothes.
  • Korean Patent No. 10-0563560 discloses "a phytoprotein synthetic fibre” which is composed of vegetable protein and polyvinyl alcohol. Based on the total amount of these two materials, the amount of the vegetable protein that is used is 5 to 23 parts and the polyvinyl alcohol (B, parts) is used in an amount of from 77 to 95 parts.
  • the phytoproteins are prepared from beans, peanuts and cottonseeds by pulverizing them to separate proteins in a wet manner to separate proteins, skimming the proteins and coagulating the skimmed proteins.
  • the fibers manufactured using this method are highly permeable to air and have properties similar to those of cashmere, but are not unsuitable for use in clothes due to their poor strength and durability.
  • the electroconductive fibers are too expensive to be used suitably in general clothes.
  • the present invention provides a synthetic fiber containing a plant fatty acid in an amount of from 0.01 to 10.0 wt%.
  • the present invention provides a method for manufacturing a synthetic fiber, comprising incorporating a plant fatty acid in an amount of from 0.1 to 10.0 wt% into a fiber-formable polymer and melt-spinning the plant fatty acid-incorporated polymer.
  • Examples of the plant fatty acids useful in the present invention include linoleic acid, oleic acid, stearic acid, palmitic acid, licanic acid, and ricinol acid, which are abundantly found in linseed oil, sunflower seed oil, rapeseed oil, camellia oil and castor oil.
  • Extraction of fatty acids may be accomplished using a solvent method or a heat compression method. Preferable is the latter. The reason is that volatile matters with low molecular weights are removed naturally from the plants during compression at a typical temperature of 80 ⁇ 220°C. When volatile matters with low molecular weights are contained within the fiber-formable polymer, the resulting fibers are likely to have poor physical properties because the matters are evaporated or degraded at relatively low temperatures.
  • Incorporating the antibacterial plant extract into the fiber-formable polymer may be carried out by (i) coating synthetic resin chips with plant fatty acids, and melt spinning the coated chips or compounding the coated chips into master batch chips, (ii) preparing a master batch chip in the presence of the plant fatty acids and melt spinning the master batch chip alone or in combination with another typical synthetic chip, (iii) feeding plant fatty acids to a melting zone of an extruder, or (iv) adding the plant fatty acids during the polymerization of the fiber-formable polymer.
  • Preferable is the method of (iii) in order to minimize the thermal degradation of plant fatty acids.
  • suitable control is necessary to prevent the pressure of the extruder from decreasing.
  • drying be conducted using a rotary-type hot-air drier or a radio-frequency drier least in order to minimize the thermal degradation of plant fatty acids during a drying process.
  • the plant fatty acids may be emulsified with water in the presence of an emulsifier.
  • the plant fatty acids are used in an amount of is from 0.1 to 10 wt%.
  • an amount exceeding the upper limit makes it difficult to manufacture fibers and has an adverse influence on the physical properties of the fibers.
  • additives such as antioxidants, thermal stabilizers, viscosity improvers, etc. may be used in the melt spinning process.
  • plant fatty acids may be heated in air or under an aerobic condition to improve the binding rate.
  • the synthetic fibers of the present invention exhibits excellent bulkiness, elasticity, whiteness, touch sensation, hygroscopicity, dyeability, and gloss. Further, the fibers of the present invention are highly antistatic, with a surface resistivity of less than 1.0 ⁇ 10 14 ( ⁇ ), and give off a plant fragrance. Therefore, they are useful as material for high-quality clothes.

  • the resulting coated chips were mixed at a weight ratio of 1: 2 with ordinary polypropylene chips and melt-spun at 230°C using a pilot spinning machine to produce 500 g of 150 denier/28 fila filaments.
