Abstract
The present invention relates to one kind of wool felt proofing agent of amino siloxane and its preparation process and application. The wool felt proofing agent consists of amino siloxane, organic solvent and water in the molar ratio of 1 to 0-10 to 1-100. It is prepared through dissolving amino siloxane or its mixture with organic solvent in water, and stirring until reaching room temperature. It is applied for the felt proofing finishing of wool fabric. It has low cost, simple preparation process, environment friendship, and capacity of endowing wool fabric with excellent felt proofing performance.
Description
Technical field
The invention belongs to the feld proofing field, particularly relate to aminosiloxane wool felt-proofing finishing agent, its preparation method and application thereof.
Background technology
Sol-gel process (Sol-Gel method) be the preparation material wet chemical method in emerging method.This method was controlled at the preparation material initial stage, made uniformity can reach submicron order, nano-scale, and goods get the uniformity, the purity height, and treatment temperature is lower than conventional method.Since the eighties in 20th century, sol-gel process is widely used in special glass, fibrous material such as inorfil and film, functionality ceramic material and oxide coating comprise aspects such as nano composite material with the composite that various conventional methods are difficult to prepare, and have become one of focus of material science research.
Woolens' forward leisureization, popular, light and thin type direction develop for many years, summer and wear next to the skin and need the woolen knitwear of frequent washing also popular day by day.In order to make Woolens reach standards such as easy maintenance, machine washable and apparel appearance retentivity are good, be necessary wool fabric is carried out feld proofing.
At present remain chloridizing or chlorination/He Ketefa (Hercosett) method at the most frequently used felt-proofing finishing method of industrial quarters, these two kinds of methods all can produce the adsorbable organohalogen compounds (AOX) that environment had harm.Therefore, it is imperative to develop novel preventing felting and shrinking of wood fabric technology.
Sol-gel technique produces the nanoscale sol particles by the hydrolysis and the polycondensation of metal or nonmetal alkoxide, and the method for adopt dipping, padding or spraying is applied to fabric with it and gets on; It is crosslinked by heating collosol and gelization also further to be taken place again, forms the continuous three-dimensional network structure, covers the wool scale surface with transparent porous membrane form, thereby gives wool fibre durable felt proofing performance.
Summary of the invention
The purpose of this invention is to provide a kind of aminosiloxane wool felt-proofing finishing agent, its preparation method and application thereof.The present invention is based on sol-gel technique, having the dialkoxy silicane of amido functional group or trialkoxy silane and water is main raw material, the wool anti-felting finish agent of preparation nanoscale colloidal sol, after putting in order on the fabric by heat treatment, form transparent porous membrane at wool surface, give its durable felt proofing performance, be used for the Wool fabric anti-felting arrangement.
Aminosiloxane wool felt-proofing finishing agent of the present invention is to be prepared by amino silicone, organic solvent and water, and their mol ratio is respectively 1: 0～10: 1～100.
Described amino silicone is dialkoxy silicane or the trialkoxy silane with amido functional group, as (β-aminoethyl)-γ-An Bingjisanjiayangjiguiwan, (β-aminoethyl)-gamma-aminopropyl-triethoxy-silane, (β-aminoethyl)-γ-aminopropyl methyl dimethoxysilane, (β-aminoethyl)-γ-aminopropyl methyldiethoxysilane, γ-An Bingjisanjiayangjiguiwan, gamma-aminopropyl-triethoxy-silane, γ-aminopropyl methyl dimethoxysilane, γ-aminopropyl methyldiethoxysilane, phenylamino MTMS and phenylamino MTES etc.;
Described organic solvent is the organic solvent that dissolves each other with water, as methyl alcohol, ethanol, ethylene glycol, acetone, acetonitrile etc.
The preparation method of aminosiloxane wool felt-proofing finishing agent of the present invention is that the mixture with amino silicone or itself and organic solvent adds in the entry, stirs to room temperature.
Aminosiloxane wool felt-proofing finishing agent of the present invention can be used for the Wool fabric anti-felting arrangement.
Described wool fabric be wool or with the interweaving of other any textile fabric such as natural, artificial and synthetic fiber, BLENDED FABRIC;
Described application process is that wool fabric is flooded in aminosiloxane wool felt-proofing finishing agent, pads or sprays, liquid carrying rate 70-80%, in the dryer 60-100 ℃ preliminary drying 1-3 minute, baked 1-3 minute at 120-180 ℃ then.
The present invention selects for use and contains amino silicone and prepare wool anti-felting finish agent as presoma, can produce multiple bonding with the amino acid residue in the wool fibre, in conjunction with stable, only need common equipment that wool fabric is handled and promptly reach excellent felt proofing index.
Beneficial effect of the present invention:
(1) aminosiloxane wool felt-proofing finishing agent is with low cost, and preparation is simple, environmental protection and energy saving;
(2) finishing agent itself has strong osmosis to fiber, and the heat treatment after-condensation forms tridimensional network and in the fiber surface film forming, thereby gives fabric good anti-felting performance;
(3) select for use and contain amino siloxanes, strengthen the binding ability of finishing agent and wool fibre, improved the durability of putting in order, and further strengthened anti-felting ability as presoma.
