Definitions

  • the present invention relates to a hybrid fiber and a method for fabricating the same and, more particularly, a hybrid fiber having excellent mechanical properties and being able to be prepared at considerably low cost and a method for fabricating the same.
  • hetero filaments having different characteristics are mixed by any known method for fabricating a hybrid fiber, characteristics of individual filaments are separately expressed, which in turn cannot attain synergistic effects. For instance, in the case where external force is applied to a hybrid fiber composed of hetero filaments having different strains, all the filaments together do not resist such external force, however, a filament having relatively low strain initially endures such external force then fails (that is, cuts off). Following this, another filament having relatively high strain endures the external force then fails.
  • the hybrid fiber as described above may be advantageous in terms of production cost, a problem is encountered in achieving desired physical properties satisfying expected levels thereof.
  • the present invention relates to a hybrid fiber enabling prevention of problems based on limitations and/or disadvantages of the related art described above, as well as a method for fabricating the same.
  • An aspect of the present invention is to provide a hybrid fiber having excellent mechanical properties while being fabricated at a relatively low cost.
  • Another aspect of the present invention is to provide a method for fabricating a hybrid fiber having excellent mechanical properties while being fabricated at a relatively low cost.
  • a hybrid fiber including: a first filament; and a second filament different from the first filament, wherein a strength-strain curve of the hybrid fiber measured according to ASTM D 885 has at least one peak, provided that, if the strength-strain curve has at least two or more peaks, a difference in strain between a first peak having the lowest strain and a second peak having the highest strain, among the above two or more peaks, is 3% or less.
  • a method for fabricating a hybrid fiber including: preparing a first filament; preparing a second filament having higher strain than that of the first filament; applying tension to the second filament, to maintain a difference in strain between the first and second filaments to 3% or less; and combining the first and second filaments.
  • a method for fabricating a hybrid fiber including: preparing a first filament; preparing a second filament having higher strain than that of the first filament; and combining the first and second filaments, wherein a length of the first filament is longer than that of the second filament.
  • a method for fabricating a hybrid fiber including: preparing a first filament; preparing a second filament having higher strain than that of the first filament; primarily twisting the first filament at a first twist number to form a first primary twisted yarn; primarily twisting the second filament at a second twist number less than the first twist number, to form a second primary twisted yarn; and secondarily twisting the first and second primary twisted yarns.
  • a hybrid fiber formed by combining filaments having different characteristics may have new and enhanced characteristics absolutely different from characteristics of individual filaments.
  • hetero filaments forming the hybrid fiber may resist external force applied to the hybrid fiber and, as a result, the inventive hybrid fiber may have enhanced tensile strength and elasticity.
  • low price filaments may be used together with high price filaments to produce a hybrid fiber having excellent mechanical properties, not only the price competitiveness of the hybrid fiber itself but also the price competitiveness of various products manufactured using the same, for example, pseudo-tire cords, hoses, belts, cables, bullet-proof jackets, ropes, composites, or the like can be improved.
  • hybrid fiber' in the description means a fiber formed by combining different kinds of filaments, for example, a fiber fabricated by twisting nylon filaments and aramid filaments.
  • 'primary twisting' in the description means twisting of filaments and the term 'primary twisted yarn' means a twisted yarn formed through primary twisting.
  • 'secondary twisting' in the description means combining and twisting at least two strands of the primary twisted yarns and the term 'secondary twisted yarn' means a twisted yarn formed through secondary twisting.
  • 'twist number' in the description means the number of twists in a length of 1 meter and its unit is TPM (Twists Per Meter).
  • the hybrid fiber of the present invention may include different kinds of filaments. According to the present invention, such different kinds of filaments are combined while having similar strains. Consequently, the inventive hybrid fiber may have excellent tensile strength and elasticity.
  • the hybrid fiber of the present invention may include aramid filaments and nylon 66 filaments.
  • the aramid filament exhibits low shrinking stress and excellent creep properties, thus being preferable in manufacturing tire cords. Also, since the elasticity of the aramid filament is little changed even at a high temperature, the aramid filament has an advantage of considerably reducing occurrence of a flat spot phenomenon if a tire cord is manufactured using the aramid filament.
  • the aramid filament is quite expensive and may be disadvantageous in view of economical aspects in the case where it is used for manufacturing general-purpose tires.
  • a plan of mixing a nylon 66 filament having relatively favorable physical properties and moderate price with the aramid filament to fabricate a hybrid fiber and using the hybrid fiber to produce tire cords may be considered.
  • a hybrid fiber fabricated using both of the filaments may entail a problem of having tensile strength and elasticity not satisfying expected advantages.
  • hetero filaments together cannot resist external force applied to a hybrid fiber but, instead, a filament having relatively low strain initially endures the external force then breaks. Following this, another filament having relatively high strain endures the external force then beaks. As a result, mechanical properties of the hybrid fiber, such as tensile strength and elasticity, may be deteriorated. That is, an important cause of mechanical properties not up to the expected level is that hetero filaments forming the hybrid fiber separately resist the external force.
  • the present inventors developed an improved hybrid fiber with mechanical properties satisfying expected level and a method for fabricating the same.
  • the inventive hybrid fiber may be advantageously used in a wide range of applications.
  • the hybrid fiber may include; polyester filaments, polyolefin filaments, polyvinylalcohol filaments, acryl filaments, cellulose filaments, urethane filaments, wholly aromatic polyamide filaments, wholly aromatic polyimide filaments, whole aromatic polyester filaments, xylon filaments, carbon fiber, metallic filaments, mineral filaments, silicon filaments, glass fiber, etc., without being particularly limited thereto.
  • FIG. 1 illustrates a strength-strain curve of a hybrid fiber fabricated by mixing a nylon 66 filament and an aramid filament according to the present invention.
  • the strength-strain curve of a hybrid fiber known in the art (fabricated by simply mixing and twisting a low strain aramid filament as well as a high strain nylon 66 filament) has two peaks.
  • a first peak 'a' positioned in a lower strain region exhibits cut-off of the low strain aramid filament, while a second peak 'b' positioned in a higher strain region indicates cut-off of the high strain nylon 66 filament.
  • the known hybrid fiber is formed by combining filaments while maintaining strains of individual filaments, a distance between the peaks 'a' and 'b', that is, a difference in strain ( ⁇ S) is greatly increased.
  • a hybrid fiber known in the art is composed of a nylon 66 filament having 20% strain and an aramid filament having 4% strain, it may show a difference in strain of about 10% or more.
  • the difference in strain is 3% or more, it may be regarded that individual filaments endure external force applied to a hybrid fiber, respectively, without synergistic effects and, in this case, the hybrid fiber never satisfies expected levels of mechanical properties.
  • FIG. 2 illustrates a strength-strain curve of a hybrid fiber fabricated by mixing an aramid filament and a nylon 66 filament while controlling strains thereof to similar levels according to one embodiment of the present invention.
  • the hybrid fiber fabricated by mixing different types of filaments under controlled strains thereof to similar levels shows a strength-strain curve having two peaks, wherein a difference in strain is not so great. That is, a distance from a first peak 'a', which is a cut-off point of an aramid filament, to a second peak 'b', which is a cut-off point of a nylon 66 filament, that is, a difference in strain is 3% or less.
  • the inventive hybrid fiber since different types of filaments are mixed while maintaining a difference in strain thereof to 3% or less, filaments may more or less resist the external force applied to the hybrid fiber. As a result, the inventive hybrid fiber has excellent mechanical properties.
  • FIG. 3 illustrates a strength-strain curve of a hybrid fiber fabricated by mixing an aramid filament and a nylon 66 filament after controlling strains thereof to a substantially equal level.
  • a strength-strain curve of such a hybrid fiber has only one peak.
  • the fact that only one peak is present in a strength-strain curve when measuring strength and strain of a hybrid fiber means that the hybrid fiber more efficiently resists external force and has maximal mechanical properties.
  • a strength-strain curve of the hybrid fiber of the present invention according to ASTM D 885 has at least one peak, provided that, if the strength-strain curve has at least two or more peaks, a difference in strain between a first peak having the lowest strain and a second peak having the highest strain, among the above two or more peaks, is 3% or less.
  • the strength-strain curve of the inventive hybrid fiber may have only one peak.
  • This hybrid fiber can more efficiently endure external force, compared to a hybrid fiber showing a strength-strain curve having two or more peaks, thereby exhibiting superior mechanical properties.
  • the strength-strain curve of the inventive hybrid fiber may have at least two or more peaks, wherein a difference in strain between a first peak having the lowest strain and a second peak having the highest strain, among these two or more peaks, is 3% or less; and the first peak may have a higher strength than the second peak. That is, among filaments forming the hybrid fiber, a filament having relatively higher strength shows lower strain than that of a filament having relatively lower strength. Since the filament having higher strength may efficiently endure external force, compared to the filament having lower strength, it may be advantageous that the former has lower strain than that of the latter.
  • the inventive hybrid fiber may include different first and second filaments.
  • the hybrid fiber according to one embodiment of the present invention includes an aramid filament as a first filament and a nylon 66 filament as a second filament. Since the aramid filament has low shrinkage stress and elasticity substantially not changed even at a high temperature, occurrence of a flat spot phenomenon is minimized. Therefore, it may be advantageous that tire cords are manufactured using aramid filaments. However, such aramid filaments are relatively expensive, thus being unfavorable from an economical viewpoint.
  • a hybrid fiber is fabricated by mixing a nylon 66 filament having economic advantages with the aramid filament and using the hybrid fiber may produce various products such as tire cords, hoses, belts, cables, bullet-proof jackets, ropes, gloves, and so forth.
  • a content of aramid filament in the hybrid fiber ranges from 10% to 90%. If the content of aramid filament is less than 10%, a hybrid fiber does not have mechanical properties satisfying expected levels, thus not being applicable to a variety of fields. On the other hand, if the content of aramid filament exceeds 90%, it cannot accomplish a principal benefit of the hybrid fiber, that is, reduction in manufacturing costs.
  • the hybrid fiber of the present invention may be a twisted yarn.
  • the hybrid fiber in the form of a twisted yarn may have enhanced tensile strength because of concentration of filaments to form the hybrid fiber.
  • first and second filaments to form a hybrid fiber are first and second primary twisted yarns, respectively; and the hybrid fiber is a ply yarn obtained by secondarily twisting the first and second primarily-twisted yarns.
  • the hybrid fiber may be a ply yarn obtained by secondarily twisting the foregoing primary twisted yarns in an S-direction.
  • the hybrid fiber in a ply yarn form described above comprises hetero filaments (to form the hybrid fiber) strongly concentrated therebetween, thus exhibiting excellent mechanical properties.
  • the hybrid fiber may show superior adhesion to other materials such as resins. Accordingly, the inventive hybrid fiber having advantages described above may be employed in various uses such as production of tire cords, etc.
  • the first and second primary twisted yarns may have different twist numbers.
  • a first primary twisted yarn prepared by primarily twisting an aramid filament may have a twist number of 600 TPM while a second primary twisted yarn prepared by primarily twisting a nylon 66 filament may have a twist number of 200 TPM.
  • primarily twisting different types of filaments, respectively, while altering twist numbers thereof based on the strain of the filament may enable the strains of the first and second primary twisted yarns to be similar to each other artificially, and a hybrid fiber fabricated by secondarily twisting the first and second primary twisted yarns having such reduced difference in strain may have excellent mechanical properties.
  • the inventive hybrid fiber may further include a resorcinol-formaldehyde-latex (RFL) adhesive.
  • RTL resorcinol-formaldehyde-latex
  • the inventive hybrid fiber may be employed in manufacturing various products including, for example, tire cords, hoses, belts, cables, bullet-proof jackets, ropes, composites, bullet-proof gloves, etc., and may optionally further include phenol resin, urethane resin, polyvinylbutyral resin or ethylenevinyl acetate resin according to use thereof.
  • the method for fabricating a hybrid fiber according to the first embodiment of the present invention comprises: preparing a first filament; preparing a second filament having higher strain than that of the first filament; applying tension to the second filament to maintain a difference in strain between the first filament and the second filament to 3% or less; and combining the first and second filaments.

  • tension is applied to the nylon 66 filament to elongate the nylon 66 filament by 16% while the aramid filament may only receive a minimum tension enabling operation.
  • the combined first and second filaments are primarily twisted in a Z-direction, to form a primary twisted yarn.
  • two strands of primary twisted yarns prepared as described above undergo secondary twisting in an S-direction, thus completing a hybrid fiber of the present invention.

Required fineness of the hybrid fiber is different according to use thereof and, in consideration of fineness, the number of primary twisted yarns may be controlled.
  • combination may be executed by primarily twisting the first and second filaments, respectively, in a Z-direction to form primary twisted yarns; and secondarily twisting both of these filaments in an S-direction, before combining the second filament having tension applied thereto with the fist filament.
