Abstract
The invention discloses a composition covered with amylase and a preparation method thereof. The composition consists of the following ingredients by weight parts: 0.2 to 1 part of alpha-amylase, 30 to 50 parts of solid sizing grease, 0.3 to 1 part of calcium chloride, 10 to 30 parts of sodium chloride and 30 to 50 parts of native starch. 30 to 50 parts of solid sizing grease are heated into a melt state and are added into a mixing machine to be cooled to 50 to 55 DEG C and to maintain the melt state, 0.2 to 1 part of middle-temperature type alpha-amylase is poured into the grease melt in the stirring state, in addition, the mixture is slowly cooled until the melt is solidified, during the starch pulp boiling, the amylase covered by solid grease is released in heated water, and the starch is catalyzed and hydrolyzed in situ, so the molecular weight of the starch is reduced, and the sizing requirements are met.

Description
Technical field
the invention belongs to the spinning sizing agent field, are specially the diastatic composition and method of making the same of a kind of parcel.
Background technology
The low price of
starch, renewable, biodegradable, be a kind of the most common, use the widest spinning sizing agent.Starch granules contains amylose starch and two kinds of compositions of pulullan, and they all are the polymkeric substance of alpha-D-glucose.The molecular-weight average of amylose starch is 10 6 More than, the molecular-weight average of pulullan can reach 10 7 -10 9 The purpose of starch size mashing off is to make starch granules gelatinization in hot water.Because the molecular weight of starch is too high, makes that the water body viscosity behind the mashing off is very big, and is too poor to the perviousness of fiber, forms surperficial starching easily.When therefore using as slurry, starch need pass through sex change diminishes its molecular weight, reduces its water body viscosity, is convenient to the sizing infiltration.For example, acidified starch or Sumstar 190 are the chemically denatured methods commonly used of modified starch, need special processing equipment and chemical processing technology, can not avoid waste water or exhaust gas discharging fully.Adopt glycase that starch is handled and be biological degeneration starch, nontoxic, also be one of spinning sizing agent viscosity reduction denaturation method commonly used.Glycase belongs to a kind of of lytic enzyme; It is amylolytic biological catalyst; Be divided into AMS, beta-amylase, saccharifying enzyme, isoamylase and Schardinger dextrins by the degraded mode and generate enzyme, middle warm type wherein (50-70 ℃) AMS is the most frequently used and effective glycase of spinning sizing agent.
are when AMS is hydrolyzed into short chain molecule with the starch long chain molecule; Cut off the inner α-1 of starch polymer with random fashion; 4 glycosidic links and the starch molecule amount is reduced; Can generate dextrin, SANMALT-S even glucose, because of C1 carbon atom in the terminal glucose residue of product is α-configuration, so be called AMS.AMS generally can not cut off α-1,6 glucoside key, can not cut off near the α-1 of tapping point; 4 glucoside keys have kept the characteristic of pulullan in its degraded product, make that the farinaceous size transparency is better; Serous coat has toughness preferably, so enzyme denaturation starch has sizing performance preferably.Because amylatic specificity of catalyzed by amylase and high efficiency, it can be with after ative starch mixes, and completion is to the degradation modification of starch in starch mashing off process.In warm type glycase comparatively stable below 60 ℃, optimum temperature 60-70 ℃, hydrolyzed starch fast between 70-90 ℃, along with temperature raises, its speed of response quickening, inactivation is also accelerated; Subsequently slurries are warming up to more than 90 ℃, the glycase inactivation obtains the farinaceous size of stable viscosity.Therefore, the starch denaturalization method of this low cost, environmental friendliness, high-level efficiency and applications well performance is widely used at the warp sizing industrial circle.But glycase is easy inactivation in storage process, particularly mixes the back with starch and absorbs the moisture in the starch easily, and activity reduces gradually under summer high temperature storage requirement, influences diastatic stability.Therefore, need seek glycase and in starch mixture, keep its activity stabilized method.
Summary of the invention
the present invention is directed to mixture unsettled phenomenon in storage process of glycase and starch in the prior art, provide a kind of parcel diastatic composition and method of making the same.
Technical scheme of the present invention is:
The diastatic compsn of a kind of parcel, said composition is composed of the following components, and by weight, the consumption of its component does
AMS 0.2-1 part
Solid sizing grease 30-50 part
Calcium chloride 0.3-1 part
Sodium-chlor 10-30 part
Ative starch 30-50 part
described AMS is a solid particulate, and middle warm type, optimum temperature are 60-70 ℃, and optimum pH is 5-7.5, and enzyme activity is 1000-6000 U, common trade name " BF7658 enzyme ".U is the iu of enzyme activity size in the biology, refers under given conditions, representes to transform in 1 minute the required enzyme amount of the relevant group of 1 μ mol in enzyme amount or the substrate of 1 μ mol substrate.
described solid sizing grease is the mixture of animal oil and winterized stearin, or the mixture of animal oil and glyceryl monostearate, or the mixture of animal oil and winterized stearin and glyceryl monostearate, and its fusing point is adjusted to 45-50 ℃.
described animal oil is any of butter, lard or sheep oil.
described ative starch is any in W-Gum, tapioca(flour) and the wheat starch.
The diastatic preparation of compositions method of
parcel with 30-50 part solid sizing grease heating and melting, joins in the mixing machine, is cooled to 50-55 ℃, keeps molten state; Under whipped state, pour warm type AMS in 0.2-1 part into the grease melt, stir, and slowly cool to melt curing, stop to stir; Mixing crusher is put in the mixture taking-up, added 0.3-1 part calcium chloride and 10-30 part sodium-chlor after grinding, mix fragmentation particle is attenuated, cross 40 eye mesh screens; Add 30-50 part ative starch at last, mixing obtains parcel glycase compsn.
per 100 parts of ative starchs wrap up diastatic compsn with 2-3 part and mix the composition starch size; When the starch mashing off; The glycase of solid grease parcel is released in the water of heating; The situ catalytic hydrolyzed starch reduces the viscosity of farinaceous size, and this starch size is used for the textile warp starching.
parcel glycase compsn is used for mixing with ative starch the composition starch size; The storage quality guaranteed period was 1 year at least; When the starch mashing off, the glycase of solid grease parcel is released the situ catalytic hydrolyzed starch in the water of heating; The starch molecule amount is reduced, satisfy the needs of warp sizing.
the present invention is for the check of the enzyme activity stabilising effect of parcel glycase compsn; Adopt NDJ-79 type rotational viscosimeter to measure the starch size of parcel glycase compsn and ative starch composition; Add the poach slurry according to weight percent 6%, testing method is carried out according to the textile industry standard FZ/T15001-2008 of the People's Republic of China.
compared with prior art, the present invention adopts solid grease parcel glycase, mixes pulverizing with calcium chloride and sodium-chlor, the agent of adding ative starch composition starch denaturalization.Its beneficial effect is: the compsn of this denaturing agent and ative starch is in storage process, and grease protection glycase does not receive the influence of aqueous vapor, keeps diastatic activity; And in the mashing off process, the grease fusing discharges glycase, can accomplish two processes of starch mashing off and degraded simultaneously.Grease in the compsn also is the smooth agent and the softening agent of spinning sizing agent, and calcium chloride is kept diastatic activity and stability, and sodium-chlor and ative starch are the weighting agents of compsn.Compsn among the present invention is with low cost, and safety non-toxic is easy to use, and is good to the glycase stabilising effect, reduced the production cost of spinning sizing agent.
