Recron  Filament Yarn

Cationic Dyeable Yarns

  • Polyester fibres are usually dyed with specific dyeing method employing high temperature and high pressure with disperse dyes.
  • The shade of polyester fibres has lower chroma than other fibre variants because molecular structure and the crystalline structure of polyester fibres have poor affinity to dyes.
  • Recron® Cationic Dyeable Yarns have a chemical modifier copolymerised with polyester fibres during polycondensation process.
  • Recron® Cationic Polyester Yarns have superior Polarity to cationic dyes i.e., superior affinity to the bases of Cationic dyes that can be dyed in clear brilliant colours

Processing Tips
A general guide to Texturing Speeds for Recron®

  • Texturing Speeds # 600 mpm
  • Lower Primary Temperature
  • Lower Draw Ratio

Bi-shrinkage Yarns

  • Recron® Bi Shrinkage Yarns are composed of two individual components having differential shrinkage.
  • While processing this yarn with heat energy, the high shrinkage component tends to shrink more as compared to the lower shrinkage component , thereby causing the latter to form a loop. This provides raised effect on the surface of fabrics giving them extra silky texture and soft peach type effect.
  • Wide range of combinations are possible by mixing varied Components.

End Uses
Apparel: Dress Materials

Product Range
Flat: 40/28, 60/48, 60/48 NSY, 60/62, 60/96, 140/144

Flat: 100/72

Processing Tips

  • The condition of machinery should be excellent to avoid high friction.
  • Worn out guides should be replaced with new guides.
  • Twist level should be as low as possible (should not exceed 400 tpm)
  • Twist to be inserted only in TFO--preferably direct feeding. Rewinding process should be avoided.
  • Heat setting is to be strictly avoided as shrinkage level gets lost in setting

YOX yarns

  • Recron® YOX yarn is a polyester flat filament yarn using filaments of two or more different deniers.
  • It offers increased bulk , increased stiffness and bending resistance.
  • Finer filament adds to the flexibility of yarn and coarseness as usual imparts strength.
  • But at the same time coarser filaments have high bending rigidity.
  • So, fabrics produced from coarser conventional yarn for apparel wear in totality do not meet the textile requirements.
  • Fabrics produced out of such yarns lacks good handle. It is here where , Recron® YOX yarn plays a role. When a conventional filament yarn is replaced with YOX , it will increase the feel of the fabrics. The fabric will be supple and will have good handle. Drape of the fabric will be excellent. All these advantages makes YOX yarn a potential replacement coarse filament in the denier range of 150 denier and above.
  • YOX yarn is a potential replacement coarse filament in the denier range of 150 denier and above.

End Uses
Apparel: Suiting

Product Range
Flat: 250/84

Processing Tips
For better downstream performance the yarn is usually twisted and heat set

Thick and Thin Yarns

  • Recron® Thick and Thin yarns are polyester filament yarns of uneven thickness , thereby giving rise to speckled effect in the length direction of the yarn.
  • Due to uneven portion random deep and light effects can be obtained, allowing the development of a melange pattern.
  • Compared to ordinary polyester yarn, this has lower strength, greater elongation and extremely high shrinkage in boiling water. So this yarn can not be used directly in the fabrics.
  • The yarn requires preparatory treatment like twisting, intermingling/doubling and heat setting.
  • It is possible to obtain products with varying tone-to-tone contrast depending on the combination of warp and weft yarn arrangement and the dyeing method.
  • That is, in order to obtain a sprinkle coloured pattern in both warp and weft direction, this yarn is used for both warp and weft and plain or twill is used for design.
  • To obtain running in single direction this yarn is used in that direction or an irregular design is used.

End Uses
Apparel: Dress Materials, Shirting
