Description
Technical Field
The invention relates to the technical field of textiles, in particular to a water-resistant high-elasticity textile fabric and a preparation method thereof.
Background
The textile fabric is widely applied to people at present, along with the increasing improvement of the living standard of people, the market demand of the textile fabric is obviously changed, the concept of consumers is continuously updated, the textile fabric is not only durable but also more pursuit of spiritual enjoyment, and especially the requirements on the functions, the texture and the like of textile clothes are also continuously improved. At present, fabrics made of plant fibers such as cotton fibers are soft and comfortable, have good air permeability and good warm-keeping effect, but have low elasticity and small deformation amount, and cannot be used and worn in various environments.
Disclosure of Invention
The invention provides a water-resistant high-elasticity textile fabric and a preparation method thereof, aiming at solving the problems that the existing textile fabric is low in elasticity and small in deformation amount and cannot be used and worn in various environments.
In order to achieve the purpose, the invention adopts the following technical scheme:
a water-resistant high-elasticity textile fabric comprises the following raw materials in parts by mass: 40-50 parts of cotton fiber, 40-60 parts of cellulose fiber, 20-30 parts of polyester spandex fiber, 10-20 parts of nettle fiber and 10-15 parts of water-resistant polyacrylate fabric finishing agent.
According to the invention, cotton fibers, cellulose fibers and nettle fibers are used as raw materials, and polyester spandex fibers are added, so that the prepared material has high elasticity, and the application range of the fabric is expanded.
Preferably, the preparation steps of the water-resistant polyacrylate fabric finishing agent are as follows:
s1: placing sodium dodecyl sulfate and glycidyl methacrylate in water, and stirring at 40-50 deg.C for 20-30min to obtain pre-emulsion;
s2: adding butyl acrylate, methyl methacrylate, acrylonitrile and acrylamide into the pre-emulsion, stirring for 10-15min at 70-80 ℃, then adding ammonium persulfate, stirring and preserving heat for 2-3h, adjusting the pH to 7-7.5 by using 10-20 wt% of ammonia water, adding titanium dioxide water-resistant particles, and stirring uniformly to prepare the water-resistant polyacrylate fabric finishing agent.
Preferably, the water-resistant polyacrylate fabric finishing agent comprises the following raw materials in parts by weight: 3-5 parts of sodium dodecyl sulfate, 2-5 parts of glycidyl methacrylate, 100 parts of water, 15-20 parts of butyl acrylate, 35-40 parts of methyl methacrylate, 2-5 parts of acrylonitrile, 5-10 parts of acrylamide, 1-2 parts of ammonium persulfate and 1-3 parts of titanium dioxide water-resistant particles.
Preferably, the preparation steps of the titanium dioxide water-resistant particles are as follows:
a: adding 3-5 parts of titanium tetrachloride into 20-30 parts of acetic acid/acetic anhydride mixed solution, heating and refluxing at 110-130 ℃ to generate white precipitate, then adding 15-20 parts of acetic acid/acetic anhydride mixed solution again, continuously heating until the acid is completely volatilized, filtering, washing and drying, dissolving the precipitate into absolute ethyl alcohol, stirring and reacting at 200-210 ℃ for 6-12h, and drying at 70-90 ℃ after washing to prepare titanium dioxide particles;
b: placing titanium dioxide particles in an aminopropyl triethoxysilane ethanol solution to obtain amino modified titanium dioxide;
c: putting the nano zinc oxide particles into an aminopropyl triethoxysilane ethanol solution to obtain amino modified zinc oxide particles;
d: immersing 10-15 parts of amino modified titanium dioxide into polycarbodiimide, stirring for 6-12 hours to obtain polycarbodiimide filled titanium dioxide, then dispersing the polycarbodiimide filled titanium dioxide into 15-20 parts of dimethylformamide, adding 3-5 parts of amino modified zinc oxide particles and 0.1-0.2 part of hexamethylene diisocyanate, reacting for 5-7 hours at the temperature of 60-70 ℃, filtering and drying to obtain the titanium dioxide waterproof particles.
The preparation method comprises the steps of firstly preparing the titanium dioxide water-resistant particles, and then mixing the titanium dioxide water-resistant particles with the polyacrylate emulsion to prepare the water-resistant polyacrylate fabric finishing agent.
When titanium dioxide water-resistant particles are prepared, firstly titanium tetrachloride is used as a raw material to prepare titanium dioxide particles with hollow cavities and surface mesopores, then the titanium dioxide particles are soaked into polycarbodiimide and stirred to fill the polycarbodiimide into the titanium dioxide particles, and because the titanium dioxide particles and the nano zinc oxide particles are subjected to amino modification, the polycarbodiimide filled titanium dioxide and the nano zinc oxide particles are mixed and added with hexamethylene diisocyanate, isocyanate groups at two ends of the hexamethylene diisocyanate can respectively react with amino active groups on the surfaces of the titanium dioxide particles and the nano zinc oxide particles, so that the nano zinc oxide particles are grafted on the surfaces of the carbodiimide filled titanium dioxide, and meanwhile, the surface mesopores are plugged, and the titanium dioxide water-resistant particles are prepared. After the water-resistant polyacrylate fabric finishing agent finishes the fabric, a polyacrylate coating with titanium dioxide water-resistant particles can be formed on the surface of the fabric, firstly, the polyacrylate coating can play a water-resistant role to prevent water from contacting the fabric, when water breaks through a first defense line and contacts polyester spandex in the fabric, the polyester spandex can be hydrolyzed to generate carboxylic acid, at the moment, the titanium dioxide water-resistant particles in the coating are in an acid environment, zinc oxide nanoparticles for blocking mesopores are gradually dissolved in the acid environment, so that the acid capable of promoting hydrolysis reaction is consumed, on the other hand, polycarbodiimide in the titanium dioxide water-resistant particles can be released after the zinc oxide nanoparticles are dissolved, the polycarbodiimide can play a role in reconnecting degraded molecular chains, and thus the hydrolysis of the fabric is prevented, the water resistance of the fabric is greatly improved. In addition, the waterproof time of the fabric can be greatly prolonged by adopting the mode, and the polycarbodiimide is prevented from being consumed in advance.
In the preparation of the water-resistant polyacrylate fabric finishing agent, in order to prevent the dissolution of zinc oxide on the surface of the titanium dioxide water-resistant particles, ammonia water is adopted to adjust the pH value to 7-7.5.
Preferably, the concentration of the aminopropyltriethoxysilane ethanol solution is 1-3 wt%.
Preferably, the mass ratio of acetic acid to acetic anhydride in the acetic acid/acetic anhydride mixed solution is 2-4: 1.
A preparation method of a water-resistant high-elasticity textile fabric comprises the following preparation steps:
(1) selecting cotton fibers, cellulose fibers, polyester spandex fibers and nettle fibers according to the proportion, and spinning the cotton fibers, the cellulose fibers, the polyester spandex fibers and the nettle fibers through drawing, roving and spinning procedures;
(2) weaving the yarns to obtain grey cloth;
(3) after washing, steaming and drying, carrying out plasma treatment, and then carrying out polyacrylate grafting modification;
(4) and (3) carrying out water-resistant polyacrylate fabric finishing agent treatment on the grafted and modified grey cloth, and drying to obtain the water-resistant high-elasticity textile fabric.
Preferably, the plasma treatment is carried out under nitrogen atmosphere at 40-50W and 50-80Pa for 40-70 s.
Preferably, the polyacrylate graft modification step is as follows:
(a) placing the grey cloth in a 2-bromo-2-methylpropanoic acid (3-trimethoxysilyl) propyl ester aqueous solution to react for 12-18h, and carrying out primary initiation modification;
(b) placing 40-50 parts of hydroxymethyl acrylamide, 1-3 parts of diethylamine and 3-7 parts of cuprous bromide in 200-350 parts of methanol to obtain a mixed solution a, then dipping the gray fabric subjected to primary initiation modification into the mixed solution a, and adding 2-3 parts of ethyl 2-bromoisobutyrate to perform primary grafting for 12-20 h;
(c) immersing the gray fabric after the primary grafting into a 2-bromo-2-methylpropanoyl bromotoluene solution for reaction for 3-5h, and adding anhydrous pyridine for secondary initiation modification;
(d) placing 25-35 parts of glycidyl methacrylate, 1-2 parts of diethylamine and 2-5 parts of cuprous bromide in methanol to obtain a mixed solution b, then dipping the gray fabric subjected to secondary initiation modification into the mixed solution b, and adding 2-ethyl bromoisobutyrate to carry out secondary grafting for 2-5 h.
The water-resistant high-elasticity textile fabric is prepared by adopting the processes of spinning, weaving, grafting modification and after-finishing. The reason is that in the preparation process, the inventor finds that the combination firmness of the water-resistant polyacrylate fabric finishing agent and the grey cloth does not meet the requirement, so that the titanium dioxide water-resistant particles cannot fully exert the effect. Therefore, the gray fabric is subjected to grafting modification after being prepared, during the grafting modification, the gray fabric is subjected to plasma treatment firstly to distribute active hydroxyl groups on the surface of the gray fabric, then, the active hydroxyl groups are utilized to initiate the modification, and then, the primary grafting reaction of the polyhydroxymethacrylamide is carried out, after the grafting modification of the polyhydroxymethacrylamide, more active hydroxyl groups are endowed on the surface of the gray fabric, and then, the active hydroxyl groups are utilized to carry out the secondary grafting reaction of the polyglycidyl methacrylate again to endow active epoxy groups on the surface of the gray fabric; meanwhile, acrylamide is used as a monomer in the preparation of the water-resistant polyacrylate fabric finishing agent, so that during dipping treatment of the water-resistant polyacrylate fabric finishing agent, active epoxy groups on the surface of the grey cloth can be chemically bonded with amino groups on a molecular chain of the water-resistant polyacrylate fabric finishing agent, and the bonding firmness between a coating and the grey cloth is greatly improved. The invention adopts the secondary grafting mode to carry out modification, not only because the grafting of the poly (hydroxymethyl) acrylamide can bring more active hydroxyl groups, but also because the poly (glycidyl methacrylate) is not hydrophilic, if the poly (glycidyl methacrylate) is directly grafted, the poly (glycidyl methacrylate) is easy to curl and can not better react with the finishing agent when being treated by the finishing agent, therefore, the invention firstly carries out the grafting of the polyhydroxy methacrylamide, because the polyhydroxy methacrylamide has good hydrophilicity, and can well spread in the finishing agent when the finishing agent is used for processing, thereby driving the dispersion of the poly glycidyl methacrylate in an emulsion system, and leading the poly glycidyl methacrylate to be capable of better chemically bonding with a molecular chain in the finishing agent. Meanwhile, the time of primary grafting is longer, the time of secondary grafting is shorter, and the poly (hydroxymethyl) acrylamide with long molecular chains and the poly (glycidyl methacrylate) with short molecular chains are obtained on the surface of the grey cloth, so that the poly (hydroxymethyl) acrylamide can better drive the poly (glycidyl methacrylate) to stretch when the finishing agent is treated.
Preferably, the concentration of the 2-bromo-2-methylpropanoic acid (3-trimethoxysilyl) propyl ester aqueous solution is 2-4 wt%; the concentration of the 2-bromo-2-methylpropionyl bromotoluene solution is 2-4 wt%.
Therefore, the invention has the following beneficial effects: the fabric prepared by adding the polyester spandex and the water-resistant polyacrylate fabric finishing agent has good elasticity, can connect the molecular weights again after the fabric is hydrolyzed, and has good water resistance.
