Polypropylene fine denier
The information of products
I produced the FDY Polypropylene microfiber specifically the following advantages:
1, the lightest of the fiber: the density minimum, 40% lighter weight than cotton, 30% lighter than polyester, soft lubrication;
2, FDY Polypropylene microfiber more warmth than wool fibers: coefficient of thermal conductivity of natural fibers and synthetic fibers in the current minimum, the heat loss is lower;
3, FDY Polypropylene microfiber color fastness: dope dyeing, color fastness, after dyeing and other fiber can not be compared;
4, green fiber: made by polymerization of hydrocarbon elements, so its a good skin-friendly, can naturally degrade completely, combustion will not produce harmful gases;
Major technical data:

Application Guide
1. Iron free with temperature controlled under 100℃ due to its low melting point .
2. No exceeding 120℃ in steam setting/wet hot conditions ,and best between 70℃-80℃for dry heat setting .
3. PP may be steam set when used in weaving socks, but must with a pressure lower than cotton
4. No Using lubricants of mineral oil category to avoid damages to PP by compatibility for they both are abstracts from petroleum.
5. Avoid dry cleaning unless proved safe. Resistant to acid/ alkali , PP is still vulnerable to certain unknown organic solvents applied in the process
6. Select softeners carefully by their proposed usage
A. If affinity is required, a hydrophilic softener is used
B. If hydrophobicity is require, a hydrophobic softener is added
7. Because there is no polar group to react with general resin to generate bonds, the post treatment is not easy, resins hardly adhere, and color fastness to water is not ideal.
8. Select only cationic antistatic for PP rubs out negative charges rather than positive by PET &NYLON
9. PP is flammable, weaker than PET& NYLON; Agent is added if flame retardance is needed is needed.
10. PP is more likely to cause photo-oxidative degradation than PE&NYLION, so stabilizers are added to fabrics to stand high ultra –violet exposure outdoors, but for general apparel usage this is unnecessary.
