Definitions

  • the present invention relates to a sea-island type composite fiber used in warp knitting and a process of preparing the same. More particularly, the present invention relates to a sea-island type composite fiber used in warp knitting and a process of preparing the same which improve the quality of raised warp knif fabric as an end product, because of its excellent physical properties of yarn of an island component after dissolving a sea component.
  • the post treating process for preparing a warp knit fabric requires a large number of complex steps such as weight loss, raising, dyeing and the like, it is necessary to control the internal stress and thermal shrinkage property of yarn appropriately.
  • the sea-island type composite fiber is prepared by using alkali soluble polymer as a sea component and fiber forming polymer as an island component and by conjugated-spinning them inlO a sea-island type, which is produced mainly for the purpose of preparing a fine denier fiber.
  • the sea component of alkali soluble polymer is dissolved by treating the sea-island type composite fiber with an alkali solution, thus to prepare a fine denier fiber composed of only island components.
  • the method for preparing the fine denier fiber from the sea- island type composite fiber is advantageous in that the finer denier fiber of an excellent workability of spinning and drawing can be obtained as compared to the method for preparing the finer denier fiber by direct spinning, while it requires a process for dissolving and removing the sea component polymer, with an organic solvent in the finishing process after weaving or knitting.
  • the sea component polymer used for the sea-island type composite fiber used in warp knitting alkali soluble copolymer polyester is mainly used. The reason of which is because it is possible to dissolve the sea component from an alkali solution and weight loss facilities widely applied in the weight loss processing of general polyester fabric without using a special apparatus and the organic solvent requiring a high recovery cost.
  • the dissolution speed of the sea component is not so important because the extent that the nylon is penetrated by the alkali solution is very low in dissolving the sea component. While, if the island component is polyester, the island component is penetrated before the sea component is completely dissolved in a case that the dissolution speed of the sea component is low because the polyester is weak to alkali, for thereby abruptly degrading the physical properties of yarn after the dissolution. Resultantly, the raising property becomes poor and it is difficult to gain desirable appearance and touch of the end product.
  • the dissolution speed of the sea component is high, the occurrence of the above problems can be prevented and the alkali concentration, the dissolution temperature and time can be reduced, thereby decreasing the dissolution cost and increasing the productivity.
  • the content of a copolymer compound should be increased. However, if the content of the copolymer compound is excessively increased, the sea component becomes an amorphous polymer with no melting point but only softening point while the dissolution is improved, thus making spinning difficult.
  • the prior art techniques for preparing alkali soluble polyester used in preparing the sea-island type composite fiber includes the following methods: 1 ) method for copolymerizing dimethyl-5-sulfoisophthalate sodium salt (hereinafter, "DMIS") or polyalkyleneglycol (hereinafter, "PAG”) of a low molecular weight in a polyester polymerization process; 2) method for blending polyester with PAG of a high molecular weight; and 3) method for blending polyester polymer with PAG of a high molecular weight.

  • the present invention provides a method of preparing a sea- island type composite fiber which is useful particularly for yarn used in warp knitting, which is manufactured by the direct spin draw method and by using alkali soluble copolymer polyester as a sea component and polyester mainly consisting of polyethylene terephthalate of more than 90 mole% as an island component, wherein the method is characterized in that it satisfies the following physical properties at the same time:
  • alkali soluble copolymer polyester as a sea component and polyester mainly consisting of polyethylene terephthalate of more than 90 mole% as an island component are used, and they are conjugated-spun by a conjugated spinning spinneret 1.
  • the raising property and sea-island shaping property are improved by properly adjusting the melt viscosity of the sea component and the island component.
  • a shear flow is occurred to fiber by a pressure applied to a spinneret from an extruder during a spinning process, and the flow rate and shear rate are low in the extruder while they are very high in the spinneret.
  • the shear stress according to such a shear rate is called the melt viscosity (MV), which is different with the polymer properties.
  • sea-island component polymer having a proper melt viscosity
  • 0 oo") between the melt viscosity of island component polymer and the melt viscosity of sea component polymer at a shear rate of 9,000(1/s) is 20-70% of the difference (hereinafter, " ⁇ MV500”) between the melt viscosity of island component and the melt viscosity of sea component at a shear rate of 500(1/s). That is, the value of ⁇ MV at the spinneret should be smaller than the value of ⁇ MV at the extruder.
  • the difference ( ⁇ MV) in melt viscosity between the island polymer and the sea component polymer according to an increase of the shear rate should be reduced. Otherwise, the orientation property of the island component is decreased, the knitting property is degraded because a sufficient drawing is difficult, and raised fibers are entangled with one another in warp knit fabric.
  • Fig. 4 is a graph illustrating a change in ⁇ MV according to an increase of a shear rate. In Fig. 4, it is found that the difference in melt viscosity between the island component and the sea component is decreased gradually as the shear rate is increased.
  • MVs melt viscosity of the sea component at a shear rate of 500-9, 000(1/s)
  • MVi melt viscosity of the island component
  • melt viscosity (MVs) of the sea component is larger than the melt viscosity(MVi) of the island component polymer, the cross section shaping of the sea-island type fiber might be difficult. This causes a decrease in number of island components or the wreck of uniform formation of island components, and thusly the raising property becomes poor in raising process and it is made difficult to express the appearance and touch of an end product. Moreover, it is preferred that the difference in melt viscosity (hereinafter,
  • ⁇ MV " ⁇ MV" between the sea component and the island component is lower than 1 ,000 poises. If the difference ( ⁇ MV) in melt viscosity between the sea and island components is more than 1 ,000 poise, the island components become adhesive to one another during spinning and there may be generated unseparated fibers in which the island components are not separated even after the dissolution. Due to this, there is a risk that the fiber raising state becomes non-uniform in warp knit fabric, the appearance becomes unclean, the writing effect becomes weak and the touch becomes rough.
  • the melt viscosity of the island component polymer can be adjusted by an -intrinsic viscosity, and the melt viscosity of the sea component polymer can be adjusted by properly controlling the kinds of copolymer, content of copolymer and copolymerization conditions.
  • DIMS of 3-15 mole is copolymer into polyethylene terephthalate, to which polyethyleneglycol of 4-20 weight % having average molecular weight more than 8,000 can be added.

If the speed of the first Godet roller 1 and the second Godet roller 2 is lower than the above-mentioned range, the yarn is not sufficiently oriented and crystallized, thereby making cutting non-uniform in a after raising process and making it impossible to control a weight loss in a weight loss process.
