To keep yarn pom poms from falling apart, start by using a strong, durable yarn. When winding the yarn around the pom pom maker or cardboard, apply a moderate tension to avoid loose loops. After achieving the desired thickness, tie the center tightly with a strong thread or yarn, double-knotting it to ensure security. When cutting the loops to form the pom pom, be careful not to cut the tie that holds everything together. Trim the pom pom to even out the shape but avoid cutting too much, as this can loosen the center tie. Finally, apply a small amount of fabric glue to the center knot for extra hold, especially if the pom pom will be subject to frequent handling or washing. Properly securing the center knot and using additional reinforcement like fabric glue are key steps in ensuring the longevity of your yarn pom poms.
Copolymer: The polymerization between two or more monomers or monomers and polymers is called copolymerization, and the product obtained by copolymerization is a copolymer. Block copolymers, graft copolymers, random copolymers, regular copolymers, etc.
Homopolymer: A polymer formed by the polymerization of one monomer is called a homopolymer.
PP-H is homopolymer polypropylene (translucent), which is what we call Type I polypropylene. We can know that it is polymerized from a single polypropylene monomer and does not contain ethylene monomer in the molecular chain. The PP-H molecular chain has a high degree of regularity, so the material has high crystallinity, the highest stiffness, the highest chemical resistance and high temperature resistance, and the worst impact resistance.
PP-B is block copolymerized polypropylene (milky white), which is what we call Type II polypropylene. Its ethylene content is relatively high, generally 7-15%. In the molecular sequence, the probability that two ethylene monomers and three monomers are connected together is very high, indicating that ethylene monomers only exist in the block phase. The ethylene segments existing in the form of blocks greatly improve the impact strength of the material. However, because the isotacticity of the PP-H molecular chain cannot be reduced, the crystallinity, melting point and heat resistance of the material cannot be fundamentally improved. . PP-B pipe is a type of hot and cold water pipe. It is relatively cheap. Its heat resistance and pressure resistance are very different from PP-R.
To dye level 70 job gear in FFXIV, the gear must be the upgraded "Augmented" version, which is dyeable. Initially, you acquire the non-dyeable version upon completing your level 70 job quest. To upgrade, exchange the gear along with specific tokens or materials (often acquired from endgame activities or traders) for the "Augmented" version with an NPC vendor, such as those in Rhalgr's Reach or Eulmore, depending on the gear set. Once upgraded, you can use your preferred dye by right-clicking the gear piece in your inventory and selecting "Dye." Remember, the ability to dye gear offers customization options to personalize your character's appearance in-game.
