Abstract

A miticiding fibre fabric is prepared by chemical reaction to graft copper ions and C19H24N3O radicals to acrylic fibres. By utilizing the coaction of the said both radical groups, the bacteria and mite can be physically killed without miticide. Its advantages include no untoward and toxic by-effect to human body, and no generation of drug resistance of bacteria and mite.

Description

A kind of fabric and manufacture method thereof with acaricidal action

The present invention is a kind of have miticiding fibre fabric and manufacture method thereof, belongs to modified fibre and preparation method thereof.

Acarid is the invisible octal lices of a kind of naked eyes, is the strong anaphylactogen that causes allergic asthma.Asthma then is a kind of respiratory disease, is a kind ofly to be decided to be the worldwide chronic disease that 21 century will capture by the World Health Organization.According to reports: have 500,000,000 people to suffer from this illness in the world approximately.China has more than 2,000 ten thousand people approximately, and the U.S. has more than 1,300 ten thousand people approximately, and per 10 children of Germany just have an asthma infant.And approximately have more than 6000 people because of the asthma death toll every year.The asthma pathogenic factor is comparatively complicated, is difficult to radical cure, 80% asthmatic patient is arranged approximately to acarid allergy.It is reported that in the global asthmatic patient, the ill reason of 80% child patient and 65% adult patient is caused by acarid.Acarid is present in indoor each corner, especially bedding, as: in quilt, cotton-padded mattress, pillow, the blanket etc.It is reported that one has been used in the pillow in 10 years, the corpse of acarid and excreta thereof can account for suitable deal.People in indoor activity, especially in bed, acarid that flies upward and excreta thereof advance in the human body by nose, mouth breathing, bring out the outbreak of allergic rhinitis, nettle rash, allergic conjunctivitis, dermatitis, especially asthma.One of method of preventing and treating asthma usually is exactly to eliminate or leave anaphylactogen.(as bedding etc.) take to press down that to kill acarid or stop its procreation growth be exactly a kind of effective method on the textiles that people use always.

Textiles cleaning and sanitary purpose washing composition with acaricidal activity are disclosed in U.S. chemical abstract CA112:2192860 and WO8912673 document, but during the use of this cleaning compositions (its active ingredient is acaricide), need such as carpet, quilt cover must be killed the mite article soaks into earlier, numerous and diverse work such as washing is then used very inconvenient.

Japan Patent special public clear 43-6233, flat 1-89339 disclose two kinds and have killed the mite textiles, but can only be at chemical fibre textile; Because the chemical fibre hydroscopicity is a cotton fiber 1/5, usefulness next to the shin is uncomfortable, and easy sensitization is so this textiles discomfort is fit to do bedding.

Chinese patent publication number CN1094105A discloses a kind of expelling parasite cloth and expelling parasite protective articles, it is with the Chinese medicine tuber of stemona wide spectrum pest repellant to be permeated among cloth, this method especially is not suitable for the allergic asthma that caused by acarid, patients such as allergic rhinitis because of Chinese medicine has flavour of a drug should not make bedding.

Chinese patent publication number CN1211652A provides a kind of anti-acarid allergic asthma textiles, this textiles is by removing mite finishing agent textiles to be handled, make the condition of acarid no survival and reproduction in, thereby stop to bring out the generation of diseases such as allergic asthma with these textiless.

Yet above-mentioned various textiless all are that effect by medicine is achieved to pressing down of acarid extremely.As everyone knows, people use medicine to produce toxic and side effect to human body for a long time.And long-term drug effect also can produce drug resistance to acarid or bacterium, and finally makes medicine ineffective.

The Si Linbailan mattress of Britain is the textiles that a kind of method with physics (non-medicine) realizes removing mite.It is to have full texture structure textile product, makes acarid can't hide existence thereon and isolates with human body.But the breathable moisture permeability of this type of textiles is relatively poor, feels uncomfortable after not only using, and must be textile-like, and application is restricted.

Main purpose of the present invention provides a kind of fabric with acaricidal action, and the mite-killing and anti-biotic function that described fiber or fabric had is achieved by physics (non-medicine) method.

That secondary objective of the present invention provides a kind of fabric with acaricidal action and manufacture method.

These and other objects of the present invention will further be set forth and illustrate by following description.

The objective of the invention is to realize:, and connect the golden yellow C of X-GL by chemical reaction grafting copper ion on acrylic fiber by following technical scheme ₁₉H ₂₄N ₃ ⁺The O group.Its structure is:

Wherein, the golden yellow C of X-GL ₁₉H ₂₄N ₃ ⁺The structural formula of O group is:

Process for making: by proportioning preparation Cucl ₂/ Lacl ₃Add water and add HAC adjusting PH3-4, make its dissolving, add water again, and will put into, add Na more respectively through the acrylic fibers that deoil ₂S ₂O ₃And Nacl, control bath raio 1: (30-50), temperature is below 55 ℃, within 40 minutes time.The golden yellow small amount of H AC that uses of X-GL is dissolved again, join in the above-mentioned solution, and add NaAc and paregal O again, PH is adjusted to 4-5, and 95 ℃ of temperature in 45 minutes time, are taken out to clean and dried.

The manufacturing technique proportioning is: acrylic fibers: Cucl ₂/ Lacl ₃: Na ₂S ₂O ₃: X-GL=1: (0.1-0.2)/(0.005-0.012): (0.03-0.07): (0.003-0.006).

The proportioning that also adds NaAc, paregal O and Nacl itself and acrylic fibers in the manufacturing technique is: acrylic fibers: NaAc: paregal O: Nacl=10: (0.1-0.2): (0.05-0.15): (0.05-0.2).

Above technology is applicable to acrylic fiber, yarn and fabric.

Compared with prior art the present invention has following advantage:

1, have mite-killing and anti-biotic function, the method that adopts physics has inhibitory or killing effect to acarid and the bacterium more than 60 kinds and fungi.Is to utilize two to have synergistic group as the present invention to killing and wounding of bacterium, with after bacterium contacts, makes cell membrane, the film rupture of bacterium, and makes beyond the region of objective existences streams such as the in-house moisture content of bacterium, protein, causes bacterium death.

2, the present invention reaches with the method for physics bacterium and acarid is pressed down the purpose of killing, changed traditional Bactericidal method that chemically presses down, therefore the chemical reaction with medicine makes the deadly mechanism of bacterium completely different, it has fundamentally avoided the bad reaction of chemicals, can not make bacterium and acarid produce drug resistance yet, can not produce toxic and side effect simultaneously yet human body.
