What is the difference between man made fibers and synthetic fibers

The differences between synthetic fibers and man-made fibers are:

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.

Polyester (polyester), nylon (polyamide), polypropylene (polypropylene), acrylic (polyacrylonitrile), chlorine, spandex ......These and so on are all made of petrochemical raw materials and are synthetic fibers.

Viscose rayon, acetate rayon, cupra silk, tencel, modal, these are all made of natural cellulose fibers (bark, pulp, waste cotton yarn) as raw materials melt spinning, spinning, are all man-made fibers. Essentially, man-made fibers are not much different from cotton yarn in terms of chemical composition.

Synthetic fibers and man-made fibers, collectively referred to as chemical fibers, referred to as chemical fibers. However, at present, the term chemical fiber is gradually moving closer to synthetic fiber, and the people usually refer to "chemical fiber", and most of the cases refer to synthetic fiber.

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.

No, synthetic fibers are a type of chemical fibers, which are synthetic fibers made from synthetic polymer compounds.

A general term for chemical fibers. It is a linear organic polymer compound synthesized by polyaddition reaction or polycondensation reaction using small molecule organic compounds as raw materials, such as polyacrylonitrile, polyester, polyamide, etc. As can be seen from the classification of fibers, it belongs to a category of chemical fibers.

Cellulose is a macromolecular polysaccharide composed of glucose. Insoluble in water and general organic solvents. It is the main component of the plant cell wall.

Cellulose is the most widely distributed and abundant polysaccharide in nature, accounting for more than 50% of the carbon content of the plant kingdom. Cotton has a cellulose content of nearly 100%, which is the purest cellulose in nature**. In general wood, cellulose accounts for 40 50%, as well as 10 30% hemicellulose and 20 30% lignin.

There are several types of fiber, and cellulose is one of the branches. For example, natural fibers, such as cotton and linen products, are composed of cellulose; Chemical fibers, the composition is polymer, such as acrylic, polyester, vinylon, polypropylene, chlorine, etc.; animal fibers, such as silk, wool, etc.; optical fibers, the main component is silicon dioxide; Glass fiber, composed of sodium silicate, calcium silicate and silicon dioxide.

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, polyester) group milling.

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 fibers are one of the two major categories of chemical fibers.

Man-made fiber is a general term for a variety of chemical fibers made of 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 varieties are not grandchildren or burn the same.

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 is different now.

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 definitions.

Man-made fibers are one of the two major categories of chemical fibers. Some natural polymer compounds or their derivatives are used as raw materials, dissolved to make textile solutions, and then spun into fibers, bamboo, wood, bagasse, cotton wool, etc. are all raw materials for the manufacture of 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.

Synthetic fiber is a synthetic linear polymer with suitable molecular weight and soluble (or fusible) properties, which is spun and formed and post-processed. These polymers with fibroforming properties are often referred to as fibroforming polymers. In addition to the general superior properties of chemical fibers, such as high strength, light weight, easy to wash and dry quickly, good elasticity, and not afraid of mold, synthetic fibers of different varieties have some unique properties.

6. The conditions are different.

Compared with natural fibers and man-made fibers, the raw materials of synthetic fibers are prepared by artificial synthesis methods, and the production is not limited by natural conditions. Man-made fibers are limited by natural conditions.

The former is made entirely from chemical raw materials such as oil or coal and natural gas. The latter can be made from a variety of natural fibers or partially mixed man-made fibers, as well as from synthetic anti-natural materials such as proteins (the main component of natural silk).

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

Man-made fibers: Basically refers to viscose filament and short-fiber fabrics, which are known as rayon, rayon, etc. In addition, it also includes some rich fiber fabrics and medium and long fiber fabrics between filament and staple fibers.

Therefore, the performance of human fiber fabrics is mainly determined by the characteristics of viscose fibers.
