Description
Technical field
The present invention relates to a kind of finishing agent for preventing felting and shrinking of wood fabric and its preparation method and application, be specifically related to a kind of application overheated
The discarded keratin of water law degraded obtains finishing agent and the application on preventing felting and shrinking of wood fabric of the described discarded keratin solution degradation product.
Background technology
As the class natural fiber material used by the mankind the earliest, Pilus Caprae seu Ovis is owing to having incomparable excellent of other fibers numerous
Character, such as good springiness, hygroscopicity is strong, warmth retention property good, be difficult to contamination, gloss is soft so that wool textile conduct always
The important component part of textile raw material and exist.The wool product of different-style both can make that good springiness, feel be smooth, body bone
Abundant, gloss is the most slim, medium-thick type fabric in summer in spring and autumn, it is also possible to knit and be made for that quality is abundant, good hand feeling, warming
Property fabric in excellent winter.But, due to the uniqueness of Pilus Caprae seu Ovis self structure, tradition pure woolen fabric is in the washed journey of domestic washing machine water
In easily there is serious felting phenomenon, not only affect wool fabric style more affect its wearability so that although wool product
There is high-grade sense but be very difficult to arrange.1972, International Wool Secretariat proposed " machine washable " this concept, and it is as top grade
A kind of judgment criteria of wool product require the Pilus Caprae seu Ovis reaching this requirement under the conditions of standard wash whole take the phase in will not
There is felting phenomenon.The method used about preventing felting and shrinking of wood fabric is broadly divided into three classes, i.e. oxidizing process, coating and biological enzyme,
But due to the impact of the many factors such as environment, cost, treatment effect, the most do not occur that environmental friendliness, effect are excellent
Good and can be with the processing method of industrialized production.
Superheated water generally refers to temperature between boiling point (100 DEG C) and critical temperature (374.2 DEG C), and pressure is between 1MPa
And the aqueous water between 6MPa.Along with the rising of temperature, the density of aqueous systems reduces, and hydrogen bond action weakens, the viscosity drop of water
Low, diffusibility strengthens.The dielectric constant of water is significantly lower than aqueous water the most in this condition, and diffusion coefficient and viscosity and gas
State water is similar to.And owing to superheated water desirable pressure is relatively low, therefore the requirement to consersion unit material and design is faced far below super
Boundary's fluid and subcritical fluids.The numerous characteristics having due to superheated water, are widely used in as a kind of green solvent in recent years
The fields such as extraction, synthesis, chromatograph detection.
Rastogi S. et al. was reported in 2004 to be successfully dissolved in by the polymer combined by hydrogen bond action and is far below
The superheated water of critical temperature, such as PA4,6.Use superheated water dissolved hydrogen bond condensation material has been started in the proposition of the method, and this is novel
The beginning of environment protection method, it is possible to be generalized to biomacromolecule and other synthetic material fields.They attempt using superheated water subsequently
Prepare amino acid solution.Compared with conventional physical chemical treating process, use superheated water preparation have low stain, the shortest,
Do not use chemical reagent, purity advantages of higher.But, overheated water law is the most never applied to textile processing and arranges process
In.
Summary of the invention
In order to solve the problems referred to above, it is an object of the invention to provide a kind of finishing agent for preventing felting and shrinking of wood fabric and preparation method thereof
And application, this finishing agent is the degradation product of the discarded keratin solution prepared by superheated water method, utilizes this finishing agent to carry out felt proofing
Arrange, good finishing effect, do not affect the intensity of Pilus Caprae seu Ovis itself, fabric feeling can be improved, and there is industrial applications prospect,
This finishing agent is natural green product, pollution-free；
The preparation method technique of this finishing agent is simple, and condition is easily-controllable, and raw material is discarded keratin (Pilus Caprae seu Ovis and feather etc.), useless
Thing recycles, and does not introduce chemical reagent, environmental protection, saves the energy；
