The properties and uses
of regenerated filaments in the field of raw materials for chemical production
Abstract

This paper introduces in detail the properties and uses of regenerated filaments in the field of raw materials for chemical production. Recycled filament is a kind of fiber material regenerated from waste textiles after mechanical and chemical treatment, which is sustainable and environmentally friendly. This paper first summarizes the basic concept, preparation method and application field of recycled filament, and then discusses its properties in detail, including physical properties, chemical properties, mechanical properties and thermal properties, and finally expounds the specific use of recycled filament in the production of chemical products.

1. Introduction

With the increasing attention to environmental protection and sustainable development, recycled filament has gradually become an important material in the field of chemical production raw materials. Recycled filament is a recycled fiber made from waste textiles after a series of treatment processes. Due to its unique properties and wide range of applications, it has received more and more attention. This article will detail the nature and use of recycled filament, in order to provide a useful reference for the production of chemical products.

the properties of 2. regenerated filaments

1. Physical properties

regenerated filaments have good softness and elasticity, smooth surface and bright color. Its density, specific heat capacity, thermal conductivity and other physical indicators are similar to the original fiber, but some defects may occur in the regeneration process, such as shorter fiber length and lower strength.

2. Chemical properties
The chemical properties of
regenerated filaments mainly depend on the composition of the raw materials. Generally speaking, regenerated filaments have good chemical stability such as acid resistance, alkali resistance, and oxidation resistance, but under certain conditions, such as high temperature, high concentration of acid and alkali, degradation or chemical reactions may occur.

3. Mechanical Properties The mechanical properties of the

regenerated filaments include strength, elongation, elastic modulus, and the like. Compared with virgin fibers, the mechanical properties of recycled filaments may be slightly reduced, but after certain treatment and processing, their mechanical properties can be improved.

4. Thermal Properties The thermal properties of the

recycled filaments include thermal stability, melting point, thermal conductivity, and the like. Generally speaking, the regenerated filament has good thermal stability and can maintain its structure and performance stability in a certain temperature range.

3. the use of recycled filament

in the field of chemical production raw materials, recycled filament has a wide range of uses, the following list of several main aspects:

1. reinforced material

recycled filament can be used as a reinforcing material added to the polymer matrix, improve the mechanical properties of composite materials. For example, in the manufacture of plastic products, the addition of a certain amount of recycled filaments can improve its strength and toughness.

2. Filler Material

recycled filaments can also be added to certain chemical products as filler materials to reduce production costs and improve certain product properties. For example, in the manufacture of paper, the addition of a certain amount of recycled filaments can improve the strength and water absorption of the paper.

3. Functional material

recycled filament after a certain treatment and modification, can have some special functionality, such as antibacterial, antistatic, flame retardant and so on. These functional recycled filaments can be widely used in textiles, building materials, automotive interiors and other fields.

4. conclusion

recycled filament as a sustainable and environmentally friendly raw material for chemical production has good properties and a wide range of applications. In the future development, with the continuous improvement of regeneration technology and processing technology, the application of regenerated filament in chemical production will be more extensive.
