Natural fibers are naturally occurring fibers that can be obtained directly. Natural fibers can be divided into three kinds of plant fibers, animal fibers and mineral fibers.
1. Plant fibers Plant fibers, also known as natural cellulose fibers, are fibers obtained from seeds, fruits, stems, leaves, etc. on plants. It includes seed fibers, bast fibers, and leaf fibers.
(1) Seed fibers: such as cotton, kapok, etc.;
(2) bast fibers: such as ramie, flax, jute, castor, apocynum, etc.;
(3) leaf fibers: such as sisal, abaca and so on.
2. Animal fibers Animal fibers, also known as natural protein fibers, are fibers obtained from animal hair or glandular secretions of insects. It includes hair and glandular secretions.
(1) Hair type: refers to wool, cashmere, camel hair, rabbit hair, yak hair, etc.;
(2) glandular secretions: refers to mulberry silk, tussah silk, ramie silk, cassava silk and so on.
3. Mineral fiber Mineral fiber, also known as natural inorganic fiber, is a fiber extracted from minerals. Mainly include all kinds of asbestos.
2, chemical fiberChemical fiber refers to a fibrous object made by manual processing. Chemical fiber can be further divided into artificial fiber and synthetic fiber.
1. Synthetic Fibers Synthetic fibers, also known as recycled fibers, are fibers made from natural polymers or fiber raw materials that lose their value in textile processing. Including artificial cellulose fibers, artificial protein fibers, artificial inorganic fibers and artificial organic fibers.
(1) Artificial cellulose fiber: refers to viscose fiber, cuprammonium fiber, acetate fiber, etc.
(2) Artificial protein fiber: refers to soybean fiber, peanut fiber, etc.
(3) Artificial inorganic fibers: glass fibers, metal fibers, carbon fibers, and the like.
(4) Artificial organic fibers: fingernail (crab shell) fibers, alginate fibers, etc.
2. Synthetic fiber Synthetic fiber, which accounts for the vast majority of chemical fiber, is a fiber obtained by synthesizing organic polymers from natural small molecule compounds. Including polyester fiber, polyamide fiber, polyacrylonitrile fiber and other varieties.
(1) Polyester fiber: refers to polyester fiber, also known as Daklon, Terrellon, Teflon, etc.
(2) Polyamide fiber: refers to nylon fiber, also known as nylon, nylon, capron, etc.
(3) Polyacrylonitrile fiber: refers to acrylic fiber, also known as Orlon, cashmere, Aikelun, etc.
(4) Polyvinyl alcohol fiber: refers to vinylon fiber, also known as vinylon, mithlon, etc.
(5) Polyvinyl chloride fibers: refers to the Klon fiber, also known as Titan, Woollen, etc.
(6) Polypropylene fiber: refers to polypropylene fiber, also known as palon
(7) Polyurethane fiber: refers to spandex fiber, also known as elastic fiber, spandex fiber, etc.
(8) Other fibers: including aramid 1414, Kevlar, carbon fiber, etc.
A bump cap is a type of head protection gear that is designed to protect the wearer from minor head injuries caused by bumping into low-hanging objects or hitting the head against hard surfaces. Unlike traditional hard hats, bump caps are made of lightweight materials such as plastic or foam and are designed to be worn in low-risk environments such as warehouses, factories, and construction sites. They are also commonly used in industries such as automotive, food processing, and maintenance. Bump caps are not intended to provide protection against falling objects or high-impact collisions and should not be used as a substitute for hard hats in high-risk environments.
