After making fabrics for so many years, many friends are actually not very clear about the basic professional knowledge. Let’s take the most basic classification of textile raw materials. Say, what category does recycled polyester, which is currently most frequently asked by customers, belong to? Take a look at my analysis below and you’ll know the answer.
Classification of textile fibers
There are many kinds of textile fibers, which are divided into two categories: natural fibers and chemical fibers according to their sources and habits. Chemical fibers are also called artificial fibers by some. As the name suggests, everyone knows that natural fibers are naturally produced, such as cotton, wool, silk, and hemp. The definition of chemical fiber is that any natural or synthetic polymer or inorganic material is used. Raw materials, fibrous objects made by artificial processing. Chemical fibers can be divided into regenerated fibers (also called man-made fibers) and synthetic fibers. In fact, there is also a type of inorganic fibers that can also be classified as chemical fibers.
What is regenerated fiber?
Regenerated fiber is a fiber made from polymer dissolution or melt spinning. It was called in the early days “Man-made fiber” should be accurately named after the composition of regeneration + polymer, such as regenerated cellulose fiber, regenerated protein fiber, regenerated chitin fiber and regenerated synthetic fiber.
What are inorganic fibers?
Inorganic fiber is made by melting and dissolving inorganic substances or spinning with polymers. The naming formula for carbonized and sintered fibers is “inorganic name + fiber”, such as basalt fiber, stainless steel fiber, alumina fiber, carbon fiber, etc.
What are synthetic fibers?
Synthetic fibers are homopolymers or copolymers of organic low molecular monomers, or copolymers of polymers. A polymer obtained by mixing or compounding, and a fiber formed by spinning the melt or melt. Among synthetic fibers, there are commonly known as the six major fibers, namely polyester, nylon, acrylic, polypropylene, vinylon, and chlorine. Polyester is currently the most widely used synthetic fiber, and nylon has a special name because it originated in Jinzhou. Named nylon, it can be said to be a domestic synthetic fiber.
What kind of fiber does recycled polyester belong to?
Based on the above, the three types of fibers, regenerated fiber, inorganic fiber and synthetic fiber, are all economical fibers. Fibers formed by artificial processing, we refer to all artificial fibers as artificial fibers, that is, chemical fibers. To answer the question, what kind of fiber does recycled polyester belong to? In terms of broad categories, recycled polyester must belong to the category of chemical fibers. If it is further divided into smaller categories, it belongs to the regenerated fibers among chemical fibers.
What fiber does hair fall belong to?
Finally, let me mention the concept of fiber recycling. Recycled fiber is the general term for fibers discarded during processing or after use. It is divided into processed recycled fiber and discarded recycled fiber. The definition of recycled fibers is the waste fibers discarded in spinning processing and the waste fibers in waste products and scraps. They have little damage, are safe and hygienic, and are mostly reused; the definition of recycled fibers is the textiles after use. The fibers in the fiber are heavily damaged, multi-colored and multi-component, making it difficult to recycle. The order of recyclability is: loose fiber, batting, yarn, nonwoven, knitted, woven, coated, and dipped fabric. Fiber is a resource, regeneration is a way of recycling, and reuse is a shortcut to recycling. The recycled wool in wool spinning is a typical recycled fiber. In actual orders, we refer to recycled polyester and recycled wool as regenerated fibers. However, the recycled wool is not strictly a regenerated fiber because it does not meet the requirements. Definition of recycled fiber.
