Description
Technical Field
The invention belongs to the technical field of fabric treatment, and particularly relates to a hydrophilic finishing agent for fabrics, and a preparation method and application thereof.
Background
Nylon, also known as nylon, has a long chain structure formed by amide bond connection, and the polarity and coplanarity of amide groups in the molecule endow strong hydrogen bond acting force between fiber molecular chains, so that nylon fibers are easy to crystallize and have high crystallinity. The high crystallinity of the fiber gives the fiber high toughness, high strength, high wear resistance and elastic recovery on the one hand, and influences the hygroscopicity of the nylon fiber fabric on the other hand, so that the nylon fabric is easy to bring a smoky feel to people when being used for manufacturing intimate apparel, and in addition, the nylon fabric is easy to generate static electricity accumulation so as to adsorb dust, so that the comfort requirement of wearing the garment cannot be met.
The hydrophilic finishing is mainly a processing technology for improving the ventilation, perspiration and wearing comfort of the fabric, is simple to operate and low in cost, and can greatly improve the hydrophilicity of the nylon fabric on the premise of not changing the original performances of the fiber, thereby achieving the aim of improving the wearing comfort. The current mainstream nylon hydrophilizing agent in the market has the technical routes that (1) the treated fabric is poor in washing fastness and not durable in hydrophilicity by means of siloxane-polyether block copolymerization and depending on physical adsorption and weak crystallization, or (2) the treated fabric is endowed with good hydrophilicity, but meanwhile, the fabric is hard in hand feeling and poor in wearing fit and comfort.
Disclosure of Invention
The following is a summary of the subject matter described in detail herein. This summary is not intended to limit the scope of the claims.
The present invention aims to solve at least one of the technical problems in the prior art described above. Therefore, the invention provides a hydrophilic finishing agent for fabrics, and a preparation method and application thereof. The finishing agent prepared by the invention has good hydrophilia, washability, yellowing resistance and the like, and is suitable for after-finishing of fabrics, especially nylon and blended fabrics containing nylon.
In order to achieve the above purpose, the present invention adopts the following technical scheme:
in one aspect of the invention, a fabric hydrophilic finishing agent is provided, which comprises water and the following preparation raw materials in percentage by mass:
6-7% of hexamethylene diisocyanate trimer,
4-5% Of polyether polyol,
6-8% Of polyethylene glycol monomethyl ether,
0.5-1% Of sulfamic acid,
1-2% Of emulsifying agent,
0.5-1% Of polyether amino silicone oil,
Acetic acid 0.1% -0.3%.
In the invention, hexamethylene diisocyanate trimer rather than aromatic isocyanate is selected, so that the risk of oxidative yellowing is reduced, and in addition, the isocyanurate ring of the trimer is more stable than the uretdione structure of the dimer, thereby being beneficial to improving the water resistance. Sulfamic acid is mixed with hexamethylene diisocyanate trimer, wherein the sulfonic acid group is a hydrophilic group, and the sulfonic acid group is combined with the hexamethylene diisocyanate trimer to serve as an internal emulsified hydrophilic group, so that hydrophilicity is provided for the system, and the dispersibility of the water-based polyisocyanate is improved. Further reacts with polyether polyol to form hydrophilic polyurethane, wherein ether bond is helpful for improving hydrophilic performance, and washing fastness and flexibility of the finishing agent are enhanced.
The polyether amino silicone oil has the characteristics of good hydrophilicity, strong flexibility, excellent antistatic property and the like, and can form effective molecular chain entanglement with the waterborne polyurethane, so that the hydrophilic chain segment and the lipophilic chain segment are prevented from easily reversely migrating, microphase separation in the baking process after finishing is reduced, and the hand feeling (comprising smoothness, softness and the like) of the nylon fabric is greatly improved. In addition, due to the existence of polyether chain segments, the polyether amino silicone oil also has the auxiliary antistatic performance.
On one hand, polyethylene glycol chains (PEG chains) in polyethylene glycol monomethyl ether are rich in ether bonds (-O-), can form strong hydrogen bonds with water molecules, obviously reduce the surface tension of fibers, obviously improve the hydrophilic efficiency, meanwhile, the PEG chains can also serve as flexible arms in a crosslinked network to prevent fabric stiffness caused by excessive crosslinking so as to keep soft handfeel, on the other hand, terminal hydroxyl (-OH) of the polyethylene glycol monomethyl ether can react with isocyanate to form covalent bonds to anchor on the surfaces of the fibers, so that the washing fastness is enhanced to a certain extent, and meanwhile, the yellowing caused by polyether amino silicone oil can be reduced.
According to some embodiments of the present invention, the polyether polyol has an average molecular weight of 500 to 10000g/mol, including but not limited to 500 to 8000g/mol, 500 to 6000g/mol, 1000 to 4000g/mol, 2000 to 3000g/mol.
The average molecular weight of the polyether polyol has a certain influence on the hydrophilicity of the hydrophilic finishing agent of the fabric, and the average molecular weight is too small, so that the hydrophilicity is insufficient, but the invention discovers that the average molecular weight is too large, and the yellowing resistance of the finishing agent is reduced.
According to some embodiments of the invention, the polyether polyol comprises at least one of polyethylene glycol, polypropylene glycol, polytetrahydrofuran ether glycol, polyglycerol.
According to some embodiments of the invention, the average molecular weight of the polyethylene glycol monomethyl ether is 300-5000 g/mol, including but not limited to 300-4000 g/mol, 300-3000 g/mol, 300-2000 g/mol, 400-1500 g/mol, 500-1000 g/mol, 600-800 g/mol, 750-800 g/mol.
According to some embodiments of the invention, the polyethylene glycol monomethyl ether has a hydroxyl value of 20-200mgKOH/g, including, but not limited to, 30-150mgKOH/g, 40-120mgKOH/g, 50-100mgKOH/g, 60-90mgKOH/g.
Generally, the higher the molecular weight of polyethylene glycol monomethyl ether, the poorer the wash fastness of the prepared finishing agent, and simultaneously, the lower the hydroxyl value, the lower the density of active hydroxyl at the molecular terminal, and the stronger the yellowing resistance of the finishing agent. The invention adopts polyethylene glycol monomethyl ether with specific molecular weight and hydroxyl value to realize the balance between the washing resistance and yellowing resistance of the finishing agent.
According to some embodiments of the invention, the emulsifier comprises at least one of fatty alcohol polyoxyethylene ether, fatty acid polyoxyethylene ester, isomeric tridecanol polyoxyethylene ether.
According to some embodiments of the invention, the polyether amino silicone oil is a quaternary ammonium salt end group modified polyether amino silicone oil.
According to some embodiments of the invention, the viscosity of the quaternary ammonium salt end group modified polyether amino silicone oil is 550-950 mpa.s/25 ℃.
According to some embodiments of the invention, the average molecular weight of the quaternary ammonium salt end group modified polyether amino silicone oil is 1000-10000 g/mol (e.g. ,1000～8000g/mol、1000～6000g/mol、1000～5000g/mol、2000～4000g/mol、3000～5000g/mol、3000～4000g/mol、3000～3500g/mol), wherein the polysiloxane skeleton accounts for 50-80 wt% (e.g. 55-80 wt%, 60-80 wt%, 65-75 wt%, 65-70 wt%) of the quaternary ammonium salt end group modified polyether amino silicone oil.
According to some embodiments of the invention, the quaternary ammonium salt end group modified polyether amino silicone oil has the structure shown below: Wherein r1 is 20-200, and R 16 is C8-C18 alkyl. The quaternary ammonium salt end group modified polyether amino silicone oil disclosed by the invention has the advantages that the quaternary ammonium salt structure is introduced to replace the original primary and secondary amine structure, so that the yellowing resistance is improved, and in addition, the poor hand feeling after finishing caused by poor flexibility and film forming property due to the fact that the proportion of an organosilicon chain segment is relatively high (r1=20-200) can be improved.
According to some embodiments of the invention, the quaternary ammonium salt end group modified polyether aminosilicone is dimethylsiloxane 3- (3- ((3-cocoamidopropyl) dimethylamino) -2-hydroxypropoxy) propyl terminated acetate (CAS 134737-05-6), trade names of which may be Abil Quat 3270, abil Quat 3272, abil Quat 3474. The preferred quaternary ammonium salt end group modified polyether amino silicone oil is Abil Quat 3272, wherein R 16 is C11 alkyl, and r1=30.
In another aspect of the present invention, there is provided a method for preparing the above-mentioned hydrophilic finishing agent for fabrics, comprising the steps of:
Dehydrating polyether polyol at 110-150 ℃, cooling to 75-100 ℃, adding hexamethylene diisocyanate trimer and sulfamic acid, stirring, cooling to 60-70 ℃, adding polyethylene glycol monomethyl ether, an emulsifier and polyether amino silicone oil, stirring, cooling to 30-50 ℃, and adding acetic acid to regulate pH to 5.0-6.0, thus obtaining the polyurethane foam.
The pH of the finish affects the finish. In the case of nylon fabrics, nylon belongs to polyamide fibers, and has a large number of amide bonds on the molecular chain, and these groups are susceptible to hydrolysis reaction under strong acid (pH too low) or strong base (pH too high) conditions, resulting in breakage of the molecular chain, decrease in fiber strength, and damage to the fabric. And the isoelectric point of nylon is about 5-6, when the pH of the finishing agent is equal to the isoelectric point, the surface of the fiber is electrically neutral, and no strong electrostatic repulsive force exists. The finishing agent can be adsorbed or deposited on the surface of the fiber more uniformly and more tightly, and is not easy to be repelled by the fiber charges. This ensures uniformity and efficiency of the finishing effect (e.g., soft, antistatic, hydrophilic, etc.).
According to some embodiments of the invention, the dehydration treatment is carried out to a moisture content of 1% or less, preferably 0.5% or less, in the system.
In another aspect, the invention provides application of the hydrophilic finishing agent for fabrics in fabric finishing, wherein the fabrics are nylon or blended fabrics containing nylon.
In another aspect of the present invention, there is provided a hydrophilic fabric obtained by applying the above-mentioned fabric hydrophilic finishing agent to a fabric, removing an excessive liquid, and drying the resultant.
According to some embodiments of the present invention, the hydrophilic fabric is obtained by applying the fabric hydrophilic finishing agent to the fabric according to a bath ratio (mass ratio of fabric: finishing agent) of 1:10-30, removing excessive liquid, and drying at 120-180 ℃ (e.g., 140-160 ℃) for 3-10 minutes (e.g., 4-6 minutes);
wherein the application process is soaking for 5-20 minutes at 25-40 ℃.
According to some embodiments of the invention, the bath ratio is 1:15-30, 1:15-25, 1:20-30.
According to some embodiments of the invention, the removing of the excess liquid is performed by a press roll to a rolling redundancy of 70% -90%.
According to some embodiments of the invention, the fabric is nylon or a blended fabric comprising nylon. The blended fabric is obtained by mixing at least one of fibrilia, viscose fiber, modal fiber, spandex, terylene and polyether ester elastic fiber with nylon according to a certain proportion.
Compared with the prior art, the invention has at least the following beneficial effects:

The test steps of each test item are as follows:
(1) The hydrophilicity is measured by adopting a wetting time measuring method, namely in an environment with an average temperature of 25 ℃ and an average relative humidity of 60%, a fabric to be measured is flatly laid and tightly arranged at the opening end of a container, a drop of water is dripped at a position which is about 3cm away from the cloth cover by using a rubber head dropper, timing is started, the time when the drop of water is diffused on a sample until no specular reflection exists is recorded, a plurality of sites are measured, and the average value is taken as the diffusion duration of the fabric to be measured. The shorter the water droplet spread time, the better the hydrophilicity.
(2) Wash fastness-after 10 washes of the fabric to be tested, its hydrophilicity was tested again, and the change in hydrophilicity was compared for two times, hydrophilicity change = after-wash diffusion duration-before-wash diffusion duration.
(3) Smoothness and softness by adopting WOOL HandleMeter Feng Baoyi and AATCC hand feeling test standard to test the smoothness and softness of the fabric to be tested.
(4) Antistatic property according to AATCC76-1995 fabric antistatic test method, antistatic ohm test is conducted on test materials with preset spacing through an antistatic meter and an electrode, and the larger the antistatic ohm value (R), the poorer the antistatic capability.
(5) Whiteness test the whiteness of textile fibers was tested according to the method for whiteness test of textile fibers (GB/T17544-2008).
