Main Application Areas
of the Produced Yarn
Properties of Texturized
Yarn:
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
The main drawbacks of PP fibers are listed below:
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 of Texturized Yarn:
Moisture Transport | Lightness | Hygiene | Durability | Easy-Care | Top
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.
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 doesn’t itch and doesn’t shrink.
Lightness
PoldaYarn is a
light textile fiber, which permits to design extremely light, original and
innovative cloths.
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 don’t 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, don’t attract powders and
dust.
PoldaYarn doesn’t cause any allergic reaction and doesn’t 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 don’t damage the
cloth, which remains soft and delightful to wear even after several washings.
