Applications

Thanks to its specific characteristics of lightness, resistance, hygienic properties and comfort, produced yarn is particularly suitable for the production of:

Chenille yarn production

       

Production of fabrics for cold weather wear

Functional underwear and underwear both for men and women

              

Sport socks and active sportswear

               

The excellent resistance of pp yarn to chemical agents, its hygienic properties, the tenacity and the good tear and rubbing resistance make of pp the right yarn for the manufacturing of bed linen for hospital and of articles for medical applications. PP yarn can also be used for the production of thermally insulated and water repellent fabrics for work and sport cloths.

                 

Bulk effect, lightness, good dirt and rubbing resistance ensure good results in the production of upholstery fabrics and Rugs

Properties of Flat yarn

Introduction

The most important property of polypropylene is its versatility. It can be tailored to many fabrication methods and applications. Excellent chemical resistance, the lowest density, highest melting point (in the family of olefin fibers), and moderate cost makes it an important fiber in industrial applications. However, the poor dyeability and texturizability have limited polypropylene's applications in conventional textile industry. With the introduction of fiber denier textured yarn its use in apparel sector is becoming inevitable along with its main outlet in the industrial sector.

When polypropylene was first introduced into the market in 1950s, the product is non-crystallizable, which result in low melting point. With the introduction of isotactic commercial polypropylene a considerable increase in the crystallinity and melting point was achieved. Polypropylene has registered continued worldwide market share growth in recent years and it is predicated that consumption will still grow as polypropylene increasingly are used as substitution for other materials such as glass, metal, and some engineering plastics

 

Properties
  • fairly low physical properties

  • fairly low heat resistance

  • excellent chemical resistance, i.e. resistant to deterioration from chemicals, mildew, insects, perspiration, rot and weather

  • translucent to opaque

  • "living hinge" capability

  • low price

  • easy to process

  • good bulk and cover, 

  • very lightweight (olefin fibers have the lowest specific gravity of all fibers)

  • high strength( wet or dry)

  • abrasion resistant

  • low moisture absorption

  • stain and soil resistant

  • good washability, quick drying, unique wicking

  • resilient, moldable, very comfortable

  • thermally bondable

The main drawbacks of PP fibers are listed below:

  • Due to low melting temperature it can be ironed with low temperatures.

  • Hard to be dyed after manufacturing, except after substantial treatment and modification,

  • Poor UV and thermal stability which requires addition of expensive UV stabilizers and antioxidants to overcome this problem

Heat setting removes the residual strains and produces a defect-free and stable crystalline structure to make fiber/fabrics dimensionally stable. It also improves the percentage of overall crystallinity. The smectic structure changes to more perfect monoclinic structure during the process of heat setting if the temperature is above 70oC . At 145oC the conversion is almost complete. In comparison to predominantly smectic form, the monoclinic form does not experience any major change in crystalline structure during the course of drawing and heat setting.

Mechanical properties
The general physical properties of PP fibers are shown in Table 1. Polypropylene fibers are produced in a variety of types with different tenacities designed to suit varying market requirement. Fibers for general textile uses have tenacities in the range of 4.5-6.0 g/den. High tenacity yarns up to 9.0 g/den are produced for the use in ropes, nets and other similar applications. High performance PP fibers have been made with high strength and high modulus. The techniques include ultra-drawing, solid state extrusion and crystal surface growth. The filaments with tenacities over 13.0 g/den can be made.

Properties of Texturized Yarn:

Moisture Transport  |  Lightness  |  Hygiene  |  Durability  |  Easy-Care | Top

Moisture Transport     

PoldaYarn ensures unique comfort: thanks to its high surface tension, water, sweat and humidity are not sealed in between the fibers of the fabrics, as it happens with many other yarns but they are moved to the exterior of the fabric to evaporate quickly or, in case of double-face fabrics, to be absorbed by another fiber. 

Therefore the body remains always dry and warm and keeps constant temperature even in the most extreme weather conditions. 

Furthermore, PoldaYarn has the lowest thermal conductivity of all other fibers, and its insulating power can be compared to that of wool, but it is much lighter, it doesnít itch and doesnít shrink.

Lightness

PoldaYarn is a light textile fiber, which permits to design extremely light, original and innovative cloths.

Fabrics produced using PoldaYarn are soft, elastic and ensure total freedom of movement.

Furthermore, as to the low specific weight correspond a high metric yield and an excellent covering power it results that the use of the yarn can bring sensitive economical advantages.

Hygiene

PoldaYarn gives fabrics, greater freshness and hygiene for clothing items with unique characteristics. PoldaYarn hydrophobic properties keep bacteria, moulds and microorganisms from proliferating and avoid the formation of bad odors on fabrics and cloths, even when worn under conditions of extreme physical stress and sport movement. Dirt, spots and dust donít seal into the fibers of the fabrics, but remain on the surface ensuring an easier and faster cleaning. PoldaYarns possess excellent antistatic properties, which, besides ensuring a more pleasant and delightful wearing, donít attract powders and dust.

PoldaYarn doesnít cause any allergic reaction and doesnít itch. Therefore also those who have noises when wearing for instance wool in direct contact with the skin, will find in PoldaYarn a good alternative.

Durability

PoldaYarn is an excellent fiber for all the applications in which resistance and durability are key-factors. Its resistance to dry and wet rubbing can be compared to that of nylon. Consequently it is not subject to the unpleasant 'pilling effect'.

Its tear resistance is much better than that of other natural fibers. PoldaYarn cloths possess an excellent dimensional stability; they keep their original shape even after several washings. PoldaYarn resists perfectly to acids, alkali and organic solvents. PoldaYarn is spun-dyed, so colours remain fast, bright and permanent for a long time.

Easy-Care

Cloths produced by pp yarn are easy and fast to care: water and detergents donít damage the cloth, which remains soft and delightful to wear even after several washings.
