Fiber finishing agents can change the surface properties of fibers, thereby giving them special functions. Alfa Chemistry offers a range of fiber finishes, such as water repellents, softeners, to meet your fiber specific functional needs.
Introduction
Fiber finishing can be divided into two categories: chemical finishing and mechanical finishing. Among them, chemical finishing is finished by using chemical substances from different sources, so that the fiber can obtain characteristics and functions that cannot be obtained by other mechanical methods. These functions include, but are not limited to, softening, antibacterial, anti-mildew, anti-mite, flame retardant, anti-ultraviolet, waterproof, anti-oil, anti-static, etc.
Typical Category
Several common finisher product portfolios include:
- Handle finishing agents, such as softeners, smoothing agents, silicone series and silicone oil series.
- Insect repellent finishes such as fluorocarbons, paraffins, silicones, etc.
- Flame retardant finishing agents, such as phosphates, etc.
- Waterproof finishing agent, using long-chain alkane compound or organosilicon polymer, including fluorocarbon waterproof finishing agent, fluorine-free waterproof finishing agent, organosilicon polymer finishing agent, etc.
- Water- and oil-repellent agents, that is, have both water- and oil-repellent functions, mainly including organic fluorine finishing agents.
- Oil repellent finishing agents
- Antibacterial finishing agents, mainly including metal compounds (especially copper and silver particles), chitosan, halogenated phenol "triclosan", quaternary ammonium compounds, antibiotics and N-halamines, etc.
- Antistatic finishing agents, which act mainly by increasing the electrical conductivity of the fiber surface and reducing friction through lubrication, include phosphate esters, quaternary ammonium compounds, non-ionic compounds (ethoxylated fatty esters, alcohols and alkylamines), etc.
- UV resistant finishing agents, including titanium dioxide, 2-hydroxybenzophenone, 2-(2-hydroxyphenyl)benzotriazole, salicylic acid derivatives, aryl disubstituted acrylates and nickel chelates, etc.

Requirements For Chemical Finishing Agents
- A high effect level of modification at low cost.
- Possible effect designs, adapted to client wishes, item needs and preferred uses.
- Simple operation, simple application and wide applicability.
- Compatibility with other finishing agents, even synergistic effects.
- Reduce or eliminate environmental problems, non-toxic, biodegradable, and free of volatile organic compounds.
Applications And Research
Depending on the function of the finishing agent, the final fiber material can be applied to different fields, such as apparel, fabrics, construction, filtration, hygiene, biomedical and other broad fields. For example, the demand for antibacterial fabrics has grown significantly in recent years, and medical textiles will play an increasing role in the future world market. A number of antibacterial, antifungal, and broad-spectrum antimicrobial agents have been investigated for their ability to impart microbicidal and microbicidal activity to fibers or textiles. Examples include chlorinated phenols, silylquaternary compounds, tolysulfone compounds, inorganic compounds, silver-zeolite complexes, silver–polyhexamethylbiguanide complexes, zinc-silver/zeolite complexes, silver-zirconium salts, polyvinyl pyridines, diammonium rings, quaternary ammonium compounds, chitosan, n-halamine compounds.
