What is a fibrous material? How to prepare fibrous materials?

Fibrous material is a fibrous material formed by textile processing technology, also known as a structural materialtextile materials

Fibers are made up of a number of different unit components, and the proportions of the constituent components vary. In nature, different kinds of fibers have different physical and chemical properties and can be used for a variety of purposes. Cellulose is generally used as a natural fiber raw material.

It was first used in textiles and later in the textile industry.

Common fibrous materials.

The raw materials of textiles mainly include natural cellulose and lignin.

Aromatic compounds, nitrogenous compounds and organic acids, among others, cellulose and hemicellulose.

It is the most important fiber material. There are many varieties of textile fibers, such as cotton, linen, wool, silk, and wool. Among them, cotton is the most important fiber material, which has excellent heat resistance, moisture resistance, good hygroscopicity, strong wear resistance and other characteristics, as well as excellent varieties of cotton spinning and wool spinning.

What are the preparation methods of fiber?

The preparation method of fiber refers to the method of obtaining a fiber material with a specific function by changing the chemical structure of the fiber under certain conditions by changing its chemical structure and controlling its chemical composition by a specific means. Common fiber preparation methods mainly include: chemical method, thermodynamic method, and electrochemical method.

and photochemical methods, among others. The chemical method is mainly to change the chemical composition of the fiber by changing the chemical structure of the melt, so as to obtain the fiber with specific functions. The mechanical method is mainly the method of stretching, extruding and grinding the solution by external force to obtain the polymer in the fiber material with a specific structure.

The thermodynamic method is generally suitable for the preparation of liquid fiber materials with high melt viscosity and the preparation of polymer monomers.

What is Fiber?

Fiber is a network of fibers composed of different components or monomers, and it is mainly composed of polymer wire mesh and cellulose wire mesh. The fiber network formed by it can not only form a network structure, but also can transmit water flow through the mesh. It is a fiber composed of one or several organic molecules with different chemical structures.

Fiber materials generally refer to textile materials; Usually, some natural or synthetic substances are made into imitation solutions or solutions, and then filtered and then dosed, and finally the oil spinneret is extruded into a liquid trickle, and then solidified to form fibers.

Fiber is a substance composed of continuous filaments, which is very versatile, and is usually operated by melt spinning or solution spinning.

Synthetic fibers belong to polymer materials.

Synthetic fibers are made of polymer compounds that synthesize pin pins, and commonly used synthetic fibers are polyester, nylon, acrylic, chlorine, vinylon, spandex, polyolefin elastic yarn, etc.

Due to the easy availability of raw materials, excellent performance, wide range of uses, and rapid development, polyester has ranked first in the output of chemical fibers. The biggest feature of polyester is stable quality, good strength and wear resistance.

The fabric made of it is 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 tanic acid, weak alkali and oxidant at normal temperature.

Advantages and disadvantages of synthetic fibers:

1. Advantages of synthetic fiber: the fiber fineness is adjustable, the drawing wire is relatively rigid, the elastic wire is elastic, the thickness of a single wire is uniform, and the vast majority of conventional cross-sections are round and easy to swim, and they are straight in parallel; Most of them have high crystallinity, high orientation, high tensile breaking strength, large elongation at break, and low initial modulus.

2. Disadvantages of synthetic fibers: slippery, stiff and not fluffy to the touch, in general environment, friction is easy to produce static electricity, not only ash absorption, pollution but also electric shock and sparks when the hand touches the metal; It will also burn in case of flames, and will form molten droplets, which can cause burns in more serious cases. The gloss is not soft when matting agent is not added.

1. Fiber is a textile material.

2. Fiber material is a structural material formed by fibrous material through textile processing technology, which is also commonly referred to as textile material. The application history of fiber materials has been quite long, although there is no clear record of when this material was produced, but in ancient human times, fiber materials have always occupied an important position, fully indicating the importance of fiber materials to human development.

3. There are three types of fiber materials used in the field of electrical engineering: natural fibers (including plant fibers and animal fibers), inorganic fibers (such as asbestos, glass fibers) and synthetic fibers (such as polyester fibers, polyarylamide fibers, etc.).

In the process of purchasing clothes, consumers often pay attention to the fabric of the clothes. The term synthetic fiber often appears in the composition of clothing fabrics, so do you know what material synthetic fiber belongs to? What are the main components of synthetic fibers?

Let's take a look.

From the classification of chain song fibers, synthetic fiber is a kind of chemical fiber, which is made of synthetic linear polymer with soluble and suitable molecular weight, which is spun and formed, and processed by the rest of the process of Peng Lazheng. Tencel, modal that are common in our lives.

Viscose rayon.

They are all spun and spun from natural local mountain cellulose, and they are all synthetic fibers. People are more familiar with polyester, nylon, and acrylic.

It is also a commonly used synthetic fiber.

Synthetic fibers are synthetic polymer compounds.

It is made of polyester, polyamide, and polyacrylonitrile.

Wait. Since synthetic fibers are artificially manufactured, their production is not limited by natural conditions. Synthetic fibers not only have the superior properties of general chemical fibers, such as easy cleaning, light texture, good elasticity and high strength, but also different varieties of synthetic fibers have their different characteristics and great plasticity.

Therefore, many of the fabrics we use in our daily lives are synthetic fibers, which help to meet the functional requirements of consumers for different clothing.

<> fiber is a structured material processed by textile technology through a material material that is reintroduced to the dimension of fiber, and is generally called a textile material. Fiber can also be said to be a substance composed of filaments, there are continuous and discontinuous filament fiber-like materials, fiber is also widely used, can be used to process and weave into fiber layers, fine threads, threads and hemp rope, woven felt and other fabrics, can also be used to make paper, at the same time can also be manufactured into other materials, combined with other materials to form new composite materials. There are three main categories of fiber materials used in the electrical field, including natural fibers, which also include plant fibers and animal fibers, inorganic fibers such as asbestos, glass fibers, synthetic fibers, including polyester fibers, polyarylamide fibers, etc., among which natural fibers are important materials in the textile industry.

Natural or synthetic fibers can be made into fiber paper, or various textiles can be directly used as insulating materials including roll products, insulating lacquer cloth, lacquered silk and so on.

Chemical fiber is a polymer material, and chemical fiber is a fiber with textile properties made of natural polymer compounds or synthetic polymer compounds as raw materials, through the preparation of spinning stock solution, spinning and post-processing.

The preparation of chemical fibers is usually made into spinning melt or solution from natural or synthetic polymer substances or inorganic substances, and then filtered, measured, and extruded into a liquid fine stream by the spinneret (Menghe plate), and then solidified into fibers. At this time, the fiber is called primary fiber, its mechanical properties are very poor, and it must go through a series of post-processing processes to meet the requirements of textile processing and use. Post-processing mainly focuses on stretching and heat setting of fibers to improve the mechanical properties and dimensional stability of fibers.

There are three types of <> fibers: natural fibers, man-made fibers and synthetic fibers, which are widely used. Natural fibers can be taken and dressed directly, can be used to weave fine thread and hemp rope, etc., can be used to form a fiber layer in paper and felt, and can also be combined with other substances to form some composite materials. Man-made fibers are fiber raw materials made from substances containing natural fibers.

Synthetic fibers are synthesized from substances that do not contain fibers or proteins, and there are many types of synthetic fibers that are synthesized first and then processed into fibers. Different fibers are used for different purposes.
