Viscose filament is an important raw material for chemical production, which has many unique properties and uses. The following is a detailed introduction about the nature and use of viscose filament.

1. the properties of viscose filament

1. Physical properties: Viscose filament is a kind of fiber with luster and softness, and its appearance is similar to silk. It has good elasticity and can stretch 15-20% without breaking. At the same time, the viscose filament also has good heat resistance and light resistance.

2. Chemical properties: The main component of viscose filament is cellulose, so it has good chemical stability and can resist acid, alkali, oxidant and other chemical substances.

2. the use of viscose filament

1. textile field: viscose filament is one of the important raw materials in the textile field, which can be used to make all kinds of textiles, such as silk, knitwear, woven fabrics and so on. Because of its good luster and softness, it is often used to make high-end clothing, bedding, etc.

2. Non-woven field: Viscose filament can also be used to make non-woven fabrics, such as medical gauze, sanitary napkins, etc. Non-woven fabrics have the advantages of good air permeability and strong water absorption, so they have been widely used in practical applications.

3. field of composite materials: viscose filament can also be used in combination with other materials to produce a variety of composite materials with special properties. For example, the use of viscose filaments and glass fibers can produce composite materials with better mechanical properties. The production process of

The production process of
viscose filament mainly includes pulp preparation, alkali cellulose preparation, aging, yellowing, dissolution, spinning, drafting, pickling, washing, drying, oil treatment and other processes. Among them, pulp preparation is the key link of viscose filament production, mainly to process plant fibers into pulp suitable for spinning. Alkali cellulose preparation is the process of converting cellulose in pulp into alkali cellulose. In the spinning process, the alkali cellulose solution is extruded from the spinneret to form fiber filaments, and then after drawing, pickling, water washing and other processes, the finished viscose filaments are finally obtained.

4. the development prospects of viscose filament

With the continuous development of science and technology, the production technology and application fields of viscose filament are also expanding. In the future, viscose filament will pay more attention to environmental protection and sustainable development, continuously improve production efficiency and quality, and further expand its application fields. At the same time, with the continuous improvement of people's quality of life requirements, the demand for viscose filament in high-end textiles, non-woven fabrics and other fields will further increase. Therefore, the development prospect of viscose filament is very broad.

In short, viscose filament, as an important raw material for the production of chemical products, has unique properties and a wide range of uses. In the future development, viscose filament will continue to play an important role in bringing more comfort and convenience to people's lives.
