Abstract
The present invention relates to an antiviral and antibacterial finishing agent for fabric and non-woven fabric. Said finishing agent is made up alkyl-dimethyl-benzyl-ammonium chloride, octamethyl cyclotetrasiloxane polymer and sodium hydroxide and stirring them. After the fabric and non-woven fabric are treated by said finishing agent, said fabric and non-woven fabric possess stable and durable antiviral and antibacterial capability, and sail finishing agent does not affect the original physical property of the fabric and non-woven fabric and their appearance, and is non-toxicity and has no irritation to human body.
Description
The present invention relates to antiviral, antibacterial finishing agent, particularly fabric and nonwoven fabric carry out field antiviral, antibacterial treatment.
The hygienic finishing of textiles and nonwoven fabric also is called as antimicrobial finish, and well-known, pathogenic microorganisms has comprised bacterium and viral two large divisions, and bacterium is viral bigger to the harm of human body relatively.In a single day human body suffers the infection of bacterium, and present medical technology has enough antibacterials available to kill the bacterium of causing infection in the body; And concerning virus, at present medically can be directly to treat the medicine of the virus that in vivo causes infection of going out as pathogenic actually rare, so, effectively prevent and just seem important completely to viral disease.The present invention is this important prevention, and a kind of effective means are provided.
By inquiry with retrieval, have other weaving hygienic finishing technology now, or title antibacterial fabric technology, antibacterial fabric resists smelly technology, DC5700 as U.S. Dow.coming company, the PBH of Britain ICI company, big and the Benzalkonium chloride (selecting from " International Textile is dynamic " 1992 the 5th phases " the nearest trend and the problem of anti-bacterial purifying finish fibre ") of chemical (strain) of Japan, people's such as Lee of China Textile University generation fine jade " fabric with antibacterial finishing agent and preparation " thereof (Chinese patent application number 88 1 05618), all not mentioned their technology or the effect that possesses inactivation of viruses of the fabric of sanitary finish agent and processing or nonwoven fabric such as people's such as Tianjin Clothing Inst. Cao Jun state " antibacterial deodourizing easy-to-remove-dirt fabric and preparation method thereof and goods " (Chinese patent application number 96 1 10108.3); And its antibacterial ability of fabric after the processing or nonwoven fabric is not lasting, descends greatly through tens of its antibacterial abilities of washing.
The object of the present invention is to provide a kind of antiviral, antibacterial finishing agent, be specially adapted to fabric and nonwoven fabric are carried out antiviral, antibacterial treatment, antiviral, antibacterial ability is very lasting, stable performance, does not destroy the quality of fabric or nonwoven fabric.
For achieving the above object, the present invention adopts following technical scheme:
A kind of antiviral, antibacterial finishing agent contains:
Material 1
