From another point of view, chemical fiber oil agent can be attached to the surface of chemical fiber, so many chemical fiber manufacturers make use of this characteristic, make the fiber obtain some special function, develop high added value, novel function of chemical fiber varieties, in order to obtain a broader market. The functionalization of oil has become an important development direction of chemical oil.
Abroad is represented with the company of Japan and Germany, developed a variety of functional oil agent products.
For example,
Japan
Matsumoto has prepared a chemical fiber oil agent (JP2009223870A) with high water permeability and durability, and also developed a variety of additive products such as flame retardant, sterilization, anti-pollution and anti-virus.
Japan
Delion-4000-90 oil can give the fiber excellent water absorption performance, Delion-4010-6029A oil can give the fiber excellent water repellent performance.
Germany
Double S (Schill+Seilacher) has developed a fungicide for AFROTINTBN added to spinning oils, and a phosphorus-containing flame retardant for UKANOLES.
The United States
Dow Corning uses antibacterial oil agent and anionic surfactant to prepare antibacterial fiber with antibacterial effect.
In recent years, domestic universities and companies have also carried out a series of functional oil additives development.
For example,
Donghua university
A modified flame retardant oil (CN102691213A) for fiber field was developed. The modified flame retardant oil was obtained by blending 8.5% ~ 15% silicon-phosphorus composite flame retardant with smoothing agent, emulsifier, cluster agent and antistatic agent. The polyester fiber prepared by the modified flame retardant oil agent is transparent, light in weight, meets the requirements of environmental protection, and has high strength fire retardant performance and excellent waterproof performance.
China petroleum & chemical corporation
Yizheng chemical co., LTD has developed a uv aramid fiber (CN106592216A), to replace benzene and imidazoles anti ultraviolet absorbent, acrylonitrile uv absorber, triazine uv absorbent and hindered amine absorbent uv absorber, etc, and spinning oil mixing, adopt the way of spraying coating on the surface of aramid fiber, The uV-resistant aramid fiber was obtained, which solved the problems of poor uV-resistance and easy oxidation degradation of para-aramid fiber under UV-light.
The functional oil agent is beneficial to shorten the preparation process of functional textiles, reduce the cost and realize the product improvement of functional textiles.
For instance,
Flame retardant filament can be directly prepared into flame retardant fabric without oil removal and dyeing. It can not be treated with flame retardant coating or reduce the thickness of coating, so that the fire retardant clothing is more convenient under the condition of flame retardant, convenient fire fighting operation, and promote the replacement of fire retardant clothing.
In order to realize the development of functional textiles in many ways, the research and development of functional lubricants is essential. However, the use of functionalizing oils means that it is not necessary to use degreasing agents to remove residual oils from fabric products in the subsequent process, so the influence of spinning oils on chemical fibers needs to be further studied.
Nguyen et al. reported in spin finishes adding anionic polymer grafting modification can enhance the biocompatibility of the polyester fiber and cell adhesion, to be used for medical purposes, but also confirm the spinning oil in storage for a long time will lead to degradation of polyester fiber surface, elastic modulus is reduced, so that the original functional degradation such as biocompatibility.
Dastjerdi et al. proposed that the presence of spinning oil provided enrichment medium for the rapid propagation of microorganisms, hydrophilicity also promoted the growth of microorganisms and weakened the release of antibacterial substances. The release effect and duration of antibacterial substances could be controlled by changing polysiloxane treatment to reduce the hydrophilic effect of fiber surface. Chemical oils not only affect functionalization, but also have great influence on mechanical properties and dyeing properties of fibers, which are the factors that technicians need to consider in the subsequent development of functionalization oils.
