What is a Modifying Agent and How Does it Affect Textiles?
2023/4/20
A modifying agent is a type of chemical that can alter the properties of textile fibers or fabrics, such as color, strength, elasticity, softness, water repellency, flame resistance, or antimicrobial activity. Modifying agents can be applied to textiles during various stages of production, such as spinning, weaving, knitting, dyeing, printing, or finishing. Modifying agents can also be used to improve the performance or functionality of textiles for specific applications, such as sportswear, medical textiles, protective clothing, or smart textiles.
Modifying agents can be classified into different categories based on their chemical structure, mode of action, or function. Some examples of modifying agents are:
- Crosslinking agents: These are chemicals that can form covalent bonds between adjacent polymer chains of textile fibers or fabrics, creating a three-dimensional network that enhances the dimensional stability, wrinkle resistance, crease recovery, or stiffness of textiles. Examples of crosslinking agents are formaldehyde, glyoxal, citric acid, and melamine.
- Softening agents: These are chemicals that can reduce the friction between textile fibers or fabrics, making them smoother, softer, more flexible, or more drapable. Examples of softening agents are fatty acids, fatty alcohols, silicones, and quaternary ammonium compounds.
- Water-repellent agents: These are chemicals that can create a hydrophobic layer on the surface of textile fibers or fabrics, preventing them from absorbing water or moisture. Examples of water-repellent agents are fluorocarbons, paraffin waxes, silicones, and metal soaps.
- Flame-retardant agents: These are chemicals that can reduce the flammability of textile fibers or fabrics by interfering with the combustion process or forming a protective char layer. Examples of flame-retardant agents are halogenated compounds, phosphorus compounds, nitrogen compounds, and inorganic salts.
- Antimicrobial agents: These are chemicals that can inhibit the growth or kill microorganisms such as bacteria, fungi, or viruses on textile fibers or fabrics. Examples of antimicrobial agents are silver nanoparticles, copper nanoparticles, triclosan, and chitosan.
Modifying agents can have various effects on textiles depending on their type, concentration, application method, and interaction with other chemicals or environmental factors. Modifying agents can improve the quality and functionality of textiles by enhancing their appearance, durability, comfort, or performance. However, modifying agents can also have some drawbacks such as causing color fading, fiber degradation, skin irritation, environmental pollution, or health hazards. Therefore, it is important to select and use modifying agents carefully and responsibly.
Modifying agents are important chemicals for textile production and processing. They can modify the properties of textile fibers or fabrics to meet different requirements and demands. Modifying agents can also provide new opportunities and challenges for textile innovation and development. Modifying agents are a term that every textile lover should know and understand.
