What is the difference between natural fibers, man made fibers, and synthetic fibers

1. Differences in materials.

Natural fibers are textile fibers directly obtained from plants and animals that are originally cultivated or artificially cultivated in nature, and are important materials for the textile industry.

Man-made fibers are made from natural fibers, which are chemically treated to create an appropriate textile solution, and then reshaped into fibers.

Synthetic fibers are fibers made from synthetic polymer compounds.

2. Differences in characteristics.

Natural fibers have uneven length and fineness; Good moisture absorption and melt resistance; Strength, low elongation capacity; Good antistatic properties and other characteristics.

Man-made fibers are easy to color and the effect is more vivid; Soft, smooth, cool, and insulating, it is often the fabric of choice for clothing in hot and humid environments.

Synthetic fiber fabrics are crisp and not easy to deform, and the heat resistance of polyester is also strong; It has good chemical stability, and will not interact with weak acids, weak alkalis and oxidants at normal temperatures.

3. Differences in classification.

Natural fibers include plant fibers, which are divided into seed fibers, leaf fibers, and stem fibers; Animal fibers are divided into two categories: hair and glandular secretions.

Man-made fibers include regenerated cellulose fibers, such as viscose fibers, Fuqiang fibers, cupra fibers, etc.; cellulose ester fibers; Regenerate protein fibers, such as soybean fiber, peanut fiber, etc.

Synthetic fibers include polyester, nylon, acrylic, chlorine, vinylon, spandex, polyolefin elastic yarn, etc.

What is the difference between man-made and synthetic fibers? Synthetic fibers and man-made fibers are both chemical fibers, and synthetic fibers are fibers synthesized through chemicals, such as polyester, polypropylene, acrylic, nylon, nylon, nylon, etc. Man-made fibers are not synthetic, common such as viscose, tencel (rayon), rayon, etc.

Chemical fiber is a staple fiber or filament of an organic polymer processed by any of the following methods1, and is prepared by polymerizing organic monomer substances, such as polyamide, polyester, polyurethane or polyethylene derivative; 2. Natural organic polymers (such as cellulose, casein, protein or seaweed) are prepared by chemical changes, such as viscose fibers, cellulose acetate fibers, copper ammonium fibers or alginate fibers. In the case of chemical fibers, "synthetic" refers to the fibers referred to in paragraph 1; The term "artificial" refers to the fibres referred to in paragraph 2. For textile materials, the terms "chemical fibers", "synthetic fibers" and "man-made fibers" have the same meanings as explained above.

Fiber refers to a thin and long material. It is divided into natural fibers and chemical fibers. Chemical fibers are divided into man-made fibers and synthetic fibers, of which man-made fibers refer to natural fibers such as wood as raw materials and processed fibers by chemical processing, such as rayon, rayon, nitrocellulose, acetate, viscous fiber, etc.; Synthetic fibers refer to the monomers processed from oil, natural gas, coal and agricultural and sideline products as raw materials, and the fibers made by polymerization reaction, such as polyester, nylon, acrylic, polypropylene, vinylon and chlorine, collectively referred to as the "six major fibers".

Man-made fibers are made of some natural polymer compounds or their derivatives as raw materials, which are dissolved to make textile solutions, and then spun into fibers, bamboo, wood, bagasse, cotton wool, etc. are all raw materials for making man-made fibers. According to the shape and use of man-made fibers, they are divided into three types: rayon, rayon, and rayon. Important varieties are viscose fiber, acetate fiber, cupro fiber and so on.

Natural fibers are native to nature.

1. The raw materials are different: compared with man-made fibers, the raw materials of synthetic fibers are prepared by artificial synthesis methods, and the production is not limited by natural conditions. Synthetic fibers use small molecule organic compounds as raw materials, while man-made fibers use bamboo, wood, bagasse, cotton wool, etc. as raw materials.

2. Different classifications: synthetic fibers are divided into carbon chain synthetic fibers, such as polypropylene fiber (polypropylene), polyacrylonitrile fiber (acrylic), and polyvinyl formaldehyde fiber. Man-made fibers are divided into two types: recycled fibers and chemical fibers, of which regenerated fibers are viscose fibers made of wood and grass fibers through chemical processing.

Chemical fibers are synthetic fibers made from oil, natural gas, coal and agricultural and sideline products.

3. **Different: synthetic fibers originated more than 100 years ago, and all textile materials come from natural substances. In order to plant cotton and hemp, raise silkworms, and herd sheep, it is necessary to occupy a lot of land and consume a lot of manpower and material resources.

After the advent of chemical fibers, the situation of the textile industry's complete dependence on agriculture and animal husbandry for raw materials began to change.

Man-made fibers originated in 1848 JMercer found that when cotton cellulose was impregnated with concentrated lye, the sensitivity of the chemical reaction increased. Thereafter the British C

Cross and EBewen uses carbon disulfide to react with alkali fibers to obtain dissolved cellulose xanthroesters, thereby preparing viscose fibers.

Synthetic fibers and man-made fibers are both chemical fibers. The main difference between synthetic fibers and man-made fibers is that not only the raw materials used are different, the processes are different, and the chemical methods of processing are also different, so their properties are not the same

Synthetic fibers are made by synthesizing polymer compounds. Starting from natural gas, coal, limestone, oil, etc., or corn cobs, cottonseed husks and other crops, these simple low-molecular substances, first refine simple compounds, and then through complex chemical synthesis, make polymer compounds, and then use spinning machines to spin into various synthetic fibers. For example, polyester, nylon, acrylic, and vinylon, which are common in our daily life, are all synthetic fibers.

This is not the case with man-made fibers, which are not synthesized chemical fibers, but are made into spinning solutions from the dissolved stock solution of natural polymer compounds, so as to spin into fibers. Sugarcane, bamboo, and wood are all raw materials for man-made fibers. In general, it is made into fibers from natural materials through mechanical processing and chemical treatment, so man-made fibers are also called "recycled fibers".

Like Fuqiang fiber, acetate fiber, and viscose fiber are all man-made fibers.

In-depth understanding of fabrics, people found that there are so many types of fabrics, among which natural fibers, man-made fibers, and synthetic fibers are among the more well-known fabric types. You can learn more about this article.

1. Materials. It is understood that natural fibers are directly obtained from natural plants, animals or artificially cultivated plants and farmed animals, such as mulberry silk, wool, rabbit hair, etc. Man-made fibers are made of natural fibers as raw materials, which are chemically processed and blended into textile solutions, and then reshaped into fibers by professional machines; Synthetic fibers are fibers made directly from synthetic polymer compounds.

2. Characteristics. The length and thickness of natural fibers are uneven, and its anti-solubility, hygroscopicity, and antistatic effects are very good, and the strength and stretch are very good. Man-made fiber is good for coloring, can have various colors of fabric, it is soft, insulated, breathable, smooth, suitable for sedan chair when summer and winter clothes to make fabrics.

Synthetic fibers are not easy to deform and fluff, have strong heat resistance and good chemical stability.

3. Scope of application.

Natural fibers are mainly used to make clothes and various textiles; Man-made fibers are mainly used in textiles and industry; Synthetic fibers are used in many fields such as industry, textiles, and medicine, among which synthetic fibers are the most widely used.

1. Staple fibers are different.

The staple fibers of man-made fibers are all called "fibers" (such as viscose fibers and rich fibers), and the staple fibers of synthetic fibers are all called "fibers" (such as nylon and polyester).

2. The raw materials required are different.

Synthetic fiber is a synthetic linear polymer with suitable molecular weight and soluble (or fusible) properties, which is spun and formed and post-processed. Man-made fiber is one of the two major categories of chemical fibers.

Artificial dust code fiber is a general term for a variety of chemical fibers prepared by using certain linear natural polymer compounds or their derivatives as raw materials, which are directly dissolved in solvents or prepared into derivatives and dissolved in solvents to generate textile solutions, and then processed by spinning.

3. The main products are different.

Man-made fibers are divided into five varieties: viscose fiber, nitrate fiber, acetate fiber, cupra fiber, and artificial protein fiber. Synthetic fibers are divided into, carbon chain synthetic fibers, and hybrid chain synthetic fibers.

4. The development status is different.

The synthetic fiber market and the apparel industry are closely linked to the rapid changes, and the differentiation rate needs to be improved. As an important textile fiber, synthetic fibers have surpassed natural fibers and are widely used in various industries.

The development of the chemical fiber industry is mainly affected by the upstream raw materials and the downstream textile industry. This brings light to the development of the chemical fiber industry. The development of the textile industry provides greater development space for the application of chemical fibers, and China is constantly researching and developing the application of chemical fibers in other non-textiles.

5. **Different.

Artificial fibers and synthetic fibers are very reasonable, and artificial fibers require more manpower, labor and material resources than synthetic fibers. The ** on the market is generally higher than synthetic fibers, of course, different materials have different **, but in general it is not expensive.
