A kind of preparation method of Self-cleaning fabric
Technical field
The present invention relates to fibre self-cleaning finishing method, be specially a kind of preparation method of Self-cleaning fabric.
Background technology
Dirt on fabric comprises water-soluble dirt, oily pollutant and dust.Water-soluble dirt, oily pollutant adsorb due to dress ornament and human contact, or cause contamination by external grease (food oil or machine wet goods); Dust produces mainly due to electrostatic interaction.Antifouling and easy decontamination is two different concepts, has again inherent contact between the two.Textiles in use can stain gradually, antifouling refer to clothing textiles in use can not by water-based soils and oily dirt soak and cause contamination, also can not because the dry dust of Electrostatic Absorption or particulate be in fiber or fabric face.The arrangement making textiles have antifouling property is called soil resistant finish.
Easy decontamination refers to fabric once after staiing, dirt is easily cleaned under normal wash conditions, and fabric can not adsorb the dirt in cleaning solution in cleaning solution and become ash (namely wash from fabric the dirt got off, other positions of fabric are transferred to by cleaning solution, this phenomenon is called to wet stains again, and in repeated washing, wet contamination again has summation).The arrangement making textiles have soil release performance energy is called soil-releasing finiss.
The textiles simultaneously with antifouling and easy dirt-removing functions has self-cleaning function, has namely both had and has not easily stain, and be and for example stained with greasy dirt without washing agent, rinse with water.Corresponding finishing agent appellation self-cleaning finishing agent.For wearing fabric comes, particularly underwear, shirt etc., often washs, and the appearance style of meeting heavy damage fabric, application hindlimb unload gives its self-cleaning function, can solve this difficult problem, meet the requirement of consumer.But by the unification of antifouling and easy decontamination dual-use function on same finishing agent, and have good stability, degree-of-difficulty factor is larger.
When nano inorganic self-cleaning finishing agent can make dress ornament run into dirt, only have little a part of spot can be adsorbed onto on fabric, through certain photocatalytic self-cleaning effect, this sub-fraction spot thoroughly can be removed.In addition, the harmful bacteria for fabric also can decompose, and makes it keep clean.But the inorganic finishing agent of highly concentrated nano disperses and is applied to technically have many difficulty, simultaneously soil resistance particularly dust tightness have larger ageing, namely its self-cleaning function can reduce along with the lengthening model of Time of Administration, but in cleaning system, add organic finishing agent, this problem can be made up.Therefore, combine organic and inorganic composite self-cleaning finishing agent, there is important using value.
Summary of the invention
For the deficiencies in the prior art, the technical problem that quasi-solution of the present invention is determined is a kind of preparation method of Self-cleaning fabric, utilizes the spinning material melt spinning of special composition to prepare fabric lining, is convenient to the needs meeting the high-grade automatically cleaning textiles of exploitation.By the hierarchical structure that this combination raw materials co-blended spinning makes its surface generation micrometer structure combine with nanostructured, improve the roughness of fabric face, the self-cleaning property of fabric and water and oil repellant performance are increased substantially.
The technical solution adopted in the present invention is: a kind of preparation method of Self-cleaning fabric, is made up of the raw material of following parts by weight:

By polyvinyl chloride, polyox-yethylene-polyoxypropylene block copolymer, epoxy resin, nano titanium oxide, Sucus Luffae, nano mica powder, PSS mixing, be heated into molten condition, add butyl benzyl phthalate, cellulose esters, nano-chitosan and all the other components and mix to obtain the spinning melt of modification, the spinning melt of modification delivers to spinning machine through screw extruder, through measuring pump, melt quantitative is pressed into each spinning components, flowed out with filament state by the melt of this material of aperture intensive on spinnerets, solidify to obtain as-spun fibre through Air flow; Reoil winding, by undrawn yarn drawing-off 3-10 doubly, and namely obtain superfine Denier fibre after twisting winding, spinning fibre is woven into Self-cleaning fabric, and wherein, the orifice diameter of spinnerets is 0.01-0.12mm, and shape of spinneret is that three leaves are petal-shaped.
Further, the particle diameter of described nano titanium oxide is all between 80-120nm.
Further, described spinning machine spinning speed is 2000-7000m/min.
Further, the fiber linear density of described superfine Denier fibre can reach the 4-6 dawn.
Beneficial effect of the present invention:
(1) Self-cleaning fabric that should obtain for the preparation of the raw material configuration melt spinning of Self-cleaning fabric has good stability, repeatability;
(2) in fibre application, there is good waterproof, antifouling and soil release performance;
(3) needs of the various fiber of exploitation high-grade automatically cleaning rib-loop knitwear are met.
The present invention is directed to the various disadvantages of existing nano-titanium dioxide powder dispersion liquid or titanium dioxide Organic Alcohol working solution preparations and applicatio, the fibre that the preparation method of the Self-cleaning fabric provided obtains, there is super-hydrophobic thin oil properties, neither get wet and oily dirt free, thus reach automatically cleaning object.This nano self-cleaning technology not only makes fiber or its goods are more attractive in appearance, increase service life, and has significant society and economic benefit at environmental protection, energy-saving square mask.
