What is polypropylene Yarn?
Polypropylene (PP) is a thermoplastic “addition polymer” made from the combination of propylene monomers. It is used in a variety of applications to include packaging
for consumer products, plastic parts for various industries including the automotive industry, special devices like living hinges, and textiles.
Polypropylene yarn, which is accepted as the lightest and useful yarn used in the textile sector, is also called PP yarn. Polypropylene (PP) fiber is one of the most widely
used synthetic fibers because it is relatively inexpensive and has outstanding mechanical properties.
Due to its technical characteristics, it is widely used in many different fields and sectors such as HOME TEXTILE, SOCK, AND CARPET MANUFACTURING.
ADVANTAGES OF PP YARN
PP is Inert
It is non-reactive. Its density is least among all other polymers like Nylon or Polyester etc making it a lighter material. In general, PP fiber has excellent
chemical resistance to acids and alkalies, high abrasion resistance and resistance to insects and pests. PP is also easy to process. Its low moisture absorption helps
quick transporting of moisture.
Resistant to Bacteria and Micro-organisms
Like other synthetic fibers – nylon, acrylic, and polyester – polypropylene fibers are not attacked by bacteria or micro-organisms; they are also moth-proof and rot-proof
and are inherently resistant to the growth of mildew and mold. It has resistance against mildew and the nocuous effects of water. It even has a hygienic structure that
does not cause allergic reactions.
Polypropylene is in a more advantageous position than many other yarn variants in terms of conversion to nature and reusability. Recyclable, ecologically friendly.
Incinerates to trace ash with no hazardous volatiles.
Colour Properties – Colour Fastness
Polypropylene is dope-dyed (melt-dyed), which is the most “colorfast” at the washing of any coloring methods and produces fibers and yarns that are colorfast.
The color is incorporated within the fiber itself. The normal method of coloring other fibers is by dyeing. The minimum colorfastness rating required for fibers in many
applications is 4 – 5 (BS 1006) and ratings in the range of 4 – 6 are normal. However, polypropylene fibre is coloured during production by pigmentation – often called
‘dope dyeing’ or ‘melt dyeing’. The pigments used for polypropylene fibers give very good lightfastness ratings of 7 and higher.
Resistance to Sunlight
Strength, colorfastness, and degradation can be effectively protected by means of stabilizers.
Effect on Strength
Ultraviolet (UV) absorbers and stabilizers are incorporated in polypropylene fibers to give them the required degree of UV resistance and stability. All fibers are degraded
by sunlight, the effect varying with their physical form. Polypropylene fibers that are not stabilized against UV light will lose strength on exposure to sunlight, but the
stabilizing systems commonly used in polypropylene fibers impart a degree of UV resistance suitable for most applications.
Effect of Water on Strength
Water has no effect on the strength of polypropylene fibers, whereas cotton increases in strength when wet, and the strength of viscose rayon falls quite markedly when wet.
Moisture formed by sweat and similar causes is thrown out by its breathing structure, it does not hold moisture and water and it does not contain dirt and stain.
Polypropylene is hydrophobic and as such does not absorb water. But in carpets, the fabric is of woven, tufted, or other fabric and can absorb water due to its fabric
structure. But the adventure is that it is quick-drying.
WHY POLYPROPYLENE YARN FOR CARPETS?
Are you in need of a carpet that can stand heavy traffic and keep fresh colors for years? Then, PP is the solution. PP can be found in carpets, mats, and rugs
and can sustain a good look for longer than many of the other options. (Rocio Jaimes Gutierrez, 2019)
Polypropylene is a very light material when compared with other fibers which means that the covering power of pp is highest among all fibers that enable
manufacturers to get a much more bulky effect when using pp.
Polypropylene is very resistant to acids, alkaline. Mildews, fungus and bacteria cannot penetrate or live in polypropylene which makes it very suitable yarn
for carpet application.
Due to its very low moisture and water absorbency ( %0,05), Polypropylene is a hygienic fiber and prevents the material from the generation of bacteria and
POLYPROPYLENE IN BRAND SAPROSE PRODUCTS
Xinqing Textile was started as the forward integration of a yarn company, which is a leading manufacturer of Polypropylene Texturised and PP BCF yarn for rugs & carpets.
Xinqing Textile was started in the China domestic market to manufacture a variety of home textile products, including, sanitizing doormats, antiskid bathmats,
table linen, baskets, and more. All these products are polypropylene dominated and share the same features, with products being available at pocket-friendly prices.
All the table linen products share properties of being water-absorbent, quick-drying, and stain-resistant due to inherent PP qualities which are key beneficiary quality for a
customer’s use along with being washable, bacteria and mildew resistant making it more hygienic. The same is the case with small as well big storage baskets,
which may help you to use it in for home storage or dinner serve ware needs with hygiene.
