Abstract
The utility model is related to a kind of functionalization wool fibers that effect of formaldehyde is removed with photocatalysis, including fibrous substrate (1), there is a strata dopamine transporters film (2) on the surface of the fibrous substrate (1), and the surface adhesion of poly-dopamine carrier film (2) has photocatalytic nanometer particle (3).The functionalization wool fiber has excellent except effect of formaldehyde and catalysed particulate stability is good.
Description
Technical field
The utility model is related to functionalization wool fibers, have the function of that photocatalysis removes effect of formaldehyde more particularly to a kind of
Change wool fiber.
Background technology
It is existing after it experienced " the coal smoke type air pollution " and " air pollution of photochemical fog type " that the industrial revolution is brought
Start to endure to the fullest extent the puzzlement of the 3rd pollution phase " room air pollution " for people.Annual 2800000 people directly or indirectly dies of according to investigations
Disease caused by finishing pollution.Wherein have 1,000,000 for children.And in numerous indoor air pollutants, formaldehyde is main
Polluted gas.Indoor carpet area coverage is wide, usage time is long, has as the indoor poison gas purification class function textile of exploitation
Unique advantage and application potential, but based on traditional carpet fabric is mainly acted on beautifying and decorating at present, few other are attached
Add function, this is undoubtedly the significant wastage to resource, and therefore, a kind of carpet with photocatalysis function of removing formaldehyde of exploitation is both must
It is wanting and feasible, while the functionalization of formaldehyde is removed by the photocatalysis of indoor carpet, the function of household textiles can be promoted
Change development.
The content of the invention
The technical problem to be solved by the utility model is to provide a kind of functionalization sheep that effect of formaldehyde is removed with photocatalysis
Wool fibre can assign the carpet fabric containing the utility model functional fiber and remove formaldehyde with lasting, wear-resisting, washable photocatalysis
Function, overcome that traditional carpet at present only has beautifying and decorating effect and the defects of additional function is insufficient, added value is relatively low.
Technical solution is used by the utility model solves its technical problem：There is provided one kind, there is photocatalysis to be imitated except formaldehyde
The functionalization wool fiber of fruit.
A kind of functionalization wool fiber that effect of formaldehyde is removed with photocatalysis of the utility model, including fibrous substrate 1, institute
Stating the surface of fibrous substrate 1 has a strata dopamine transporters film 2 of in-situ polymerization, and the surface adhesion of poly-dopamine carrier film 2 is (negative
Carry) the photocatalytic nanometer particle 3 that there is part surface to be contacted with air.
The fibrous substrate 1 is wool fiber substrate.
The thickness of the poly-dopamine carrier film 2 is 2~10nm.
The poly-dopamine carrier film is that the ultra-thin poly-dopamine film of oxidation auto polymerization generation occurs for dopamine hydrochloride, should
Carrier film thickness is 2~10nm, and film has extremely strong adhesion, can securely glue substrate wool fiber and photocatalytic particle
Knot.
The thickness of carrier film 2 can not be blocked up, otherwise coats light catalyzing nano-particles completely in process, can weaken it
Function.
The photocatalytic nanometer particle 3 is titania nanoparticles.
The titania nanoparticles are anatase titanium dioxide:Rutile-type=7:The titania nanoparticles of 3 (mass ratioes).
The grain size of the photocatalytic nanometer particle 3 is 20~100nm.
The total weight of photocatalytic nanometer particle 3 is equivalent to 1~5wt.% of fibrous substrate total weight of fibers.
Overlay capacity of the photocatalytic nanometer particle 3 on unit fiber surface area is no less than 75%.
Photocatalytic nanometer particle 3 is no more than the 50% of nano-particle diameter by the adherency depth of carrier film.
It is a kind of using the carpet with photocatalysis function of removing formaldehyde fiber, in all or part of yarn of the carpet
Containing the fiber, this kind of fiber can be distributed in base fabric or pile.
In above-mentioned carpet, the carpet can be woven carpet, knotted rug and knitted carpet.
Advantageous effect
As a result of above-mentioned technical solution, the utility model compared with prior art, has the following advantages that and accumulates
Pole effect：The utility model in a manner of auto polymerization building unique ultra-thin poly-dopamine carrier on the surface of fibrous substrate
Film has stronger combination power when carrier film is generated in a manner of auto polymerization with wool fiber, because poly-dopamine has multiple chemical
With reference to power, thus it is high to the fixed fastness of photochemistry nano particle, the carpet fabric containing the fiber can be assigned with lasting, resistance to
Mill, washable photocatalysis function of removing formaldehyde, while this kind of carrier film is only 2~10nm, is uniformly implemented in individual fiber surface, is kept away
Exempt from directly using adhesive on fabric or yarn, thus be not significantly affected by the feel and style of fabric, keep the soft of fiber
It is soft.
