First, the polymer being spun must be converted into a fluid state. If the polymer is a thermoplastic then it is just melted, if not then it may be dissolved in a solvent or chemically treated to form soluble or thermoplastic derivatives. The fluid polymer is then forced through the spinneret, where the polymer cools to a rubbery state, and then a solidified state.

“Healthy parenting is nothing if not a process of empowerment. As we help to raise our children’s self-esteem, we also increase their personal power. When we encourage them to be confident, self-reliant, self-directed, and responsible individuals, we are giving them power.”
