Description

A kind of anti-uv finishing method of fabric for umbrella
Technical field
The present invention relates to the processing method of fabric, particularly relate to the processing method of fabric for umbrella, specifically a kind of anti-uv finishing method of fabric for umbrella.
Background technology
At present, mostly conventional fabric for umbrella anti-uv finishing is to adopt coating, in coating adhesive, namely adds the ultra-violet absorber (as benzophenone, azimidobenzene class etc.) of organic to reach fabric preventing ultraviolet effect.Because the UV absorber molecules amount of organic is little, the characteristics such as type difference compatible with high molecular acrylate coatings glue, cause after coating and expect that surface organic matter oozes out and volatilizees, while affecting fabric outward appearance, uvioresistant effect is also unstable.Have a strong impact on the application of uvioresistant fabrics on umbrella cover.
Summary of the invention
The present invention is to solve the problems referred to above that prior art exists, aim to provide a kind of anti-uv finishing method of novel fabric for umbrella.
For solving the problem, the present invention by the following technical solutions: a kind of anti-uv finishing method of fabric for umbrella, umbrella cover fabric grey cloth adopts 190T cationic fabric, it is characterized in that carrying out according to the following steps:
1) destarch;
2) in dye vat, dyestuff is added;
3) in dye vat, add water nano ultraviolet light screener aqueous dispersions, described water nano ultraviolet light screener aqueous dispersions is by weight by ionized water 30 parts, dispersant 0.3 part and TiO 2nanoparticle 3-3.5 part is formulated;
4) dyeing insulation 30 minutes;
5) shape;
6) WATER REPELLENT TREATMENT;
7) surface layer is applied.
According to the present invention, step 1) adopt liquid caustic soda destarch method to remove slurry on grey cloth: be added to the water with the refining agent of 4wt% liquid caustic soda and 0.8wt% and make alkali lye, fall alkali lye as contaminated pond, control temperature is at 100 DEG C, make cloth circulation 4 times in dye pond, each 3-10 second.
The anti-uv finishing method of fabric for umbrella of the present invention, adopts water nano TiO 2ultraviolet light screener carries out antiultraviolet process to umbrella cover fabric.Nano TiO 2 ability and ultraviolet resistance is strong, compared with some organic uv absorbers of same dosage, higher at the absworption peak of ultra-violet (UV) band.Have shielding to do to the UVA (320 ~ 400nm) in ultraviolet, UVB (280 ~ 320nm), and unlike organic uv absorbers that, general only solely have absorption to UVA or UVB.More particularly, water nano TiO 2ultraviolet light screener has following characteristics: the TiO of water nano ultraviolet light screener 2nanoparticle size and ultraviolet wavelength quite or less, because small-size effect causes it significantly to strengthen ultraviolet absorption; Specific area is large, and surface energy is high, is easily combined with macromolecular material; Granularity is little, has excellent anti-ultraviolet property, reach fabric for umbrella antiultraviolet standard to fabric after the diffuse reflection of visible ray.The present invention utilizes water nano TiO 2the These characteristics of ultraviolet light screener, also utilizes water nano TiO simultaneously 2ultraviolet light screener has the characteristic such as quantum size effect, macro quanta tunnel effect, and nontoxic, tasteless, nonirritant, Heat stability is good, do not decompose, non-volatile, ultraviolet-shielding type good and from as excellent properties such as whites, nano material be successfully applied on the fabric for umbrella of anti-ultraviolet function.Umbrella cover fabric rate of ultraviolet shield after process can reach more than 95%, and can play the anti-ultraviolet function of nano material enduringly.
Moreover, adopt the fabric for umbrella after process of the present invention, while having well lasting anti-ultraviolet function, also assures that original style of weaving face fabric, feel is submissive, bright-colored, good permeability, washability is good, makes the property indices of umbrella cover all reach design standard requirement, fully meet people to multi-aspect demand that is healthy, safe, attractive in appearance and fashion, there is wide commercial promise.
According to the present invention, step 1) adopt liquid caustic soda destarch method to remove slurry on grey cloth: be added to the water with the refining agent of 4wt% liquid caustic soda and 0.8wt% and make alkali lye, fall alkali lye as contaminated pond, control temperature is at 100 DEG C, make cloth circulation 4 times in dye pond, each 3-10 second.
According to the present invention, step 3) in, ionized water, dispersant and TiO2 nanoparticle added successively empty bucket and fully stir acquisition water nano ultraviolet light screener aqueous dispersions.
According to the present invention, step 4) adopt high-temperature pressure dyeing exhaustion method to carry out dyeing process, carry out insulation in 30 minutes after having dyeed, control temperature is at 130 DEG C.High-temperature pressure dyeing exhaustion method is carried out under high temperature has the humid tropical condition of pressure.Dyestuff dyeing rate within 100 DEG C is very slow, even if dye in the dye bath of boiling, dyeing rate and dye uptake are not high yet, 2atm (2.02 × 105Pa) is pressed in below so must add, dye bath temperature can bring up to 120 ~ 130 DEG C, because temperature improves, the segment strenuous exercise of fiber molecule, the instantaneous pore produced is also more and larger, the now diffusion of dye molecule also speeds, add the diffusion rate of dyestuff to fibrous inside, dyeing rate is accelerated, until dyestuff is sucked and completes dyeing.Nanometer ultraviolet ray agent molecule constantly diffuses into by fiber gap that is expanded and that increase, and with fiber by intermolecular attraction and hydrogen bond set, completes the ultraviolet finishing functions to fabric.The present invention adopts dyeing with the mode that bath High Temperature High Pressure exhaustion method dyes to fabric and anti-ultraviolet function carries out simultaneously, and both ensured nano material ultraviolet shielding effect, and made itself and fiber have good combination, the textiles simultaneously dyed is riotous with colour.
According to the present invention, in step 5) in, the fabric after dyeing is sent into baking oven with the speed of 70-80 m/min and is carried out oven dry stentering forming by setting machine, and oven temperature controls at 180 DEG C.
According to the present invention, in step 6) in, the fabric fluorine system waterproofing agent after sizing is carried out WATER REPELLENT TREATMENT to fabric, and adopt leaching one roll process, padding machine pressure 0.3MP/CM2, oven temperature controls at 160-170 DEG C, and the speed of a motor vehicle controls at 50-60M/MIN.
According to the present invention, in step 7) in, by 80-90wt% acrylate, 2-3wt% Bridge Erector, the mixing of 10-20wt% toluene and slurry to be coated on fabric by coating machine and to obtain finished product.
