Description
Technical field
The present invention relates to a kind of method that utilization ammonium dihydrogen phosphate and polyurethane improve sizing adhesive formula, belong to spinning
Knit processing technique field.
Background technology
During weaving, warp thread can be produced the reciprocating motion of 4000 times or so by the effect during warp beam to fell in heald frame.
In the process, the effect for being played as the adhesive of protection warp thread performance is to increase strength, reduces filoplume etc..Textile process
The species of three conventional big adhesives of industry is：Starch, acrylic compounds and polyvinyl alcohol.The performance of adhesive is viscous to padding
Performance after mixture through yarn plays an important role.Therefore, in order to protect warp thread, warp thread is carried out to pad adhesive, adhesive is to warp
The protection of yarn is main in terms of two：One is that adhesive is impregnated with and enters yarn interior, increases the cohesive force between fiber, forms leaching
Permeable layers, improve the ultimate strength and elongation of warp thread；Two is that adhesive is coated in yam surface, coats filoplume, forms quilt
Coating, improves the wearability of warp thread.Such as Chinese public publication《Polymer material science and engineering》, at 2009 8 publication date
Month, article name is the texture and performance of phosphate ester starch/polyacrylate blending film, and the document is described by phosphorus
Acid esters starch is aided with polyacrylate slurry, and to improve the pliability of serous coat, its weak point is that only phosphate ester starch is aided with
Third polyene acid esters come improve it is flexible to warp yam surface serous coat when the pliability of serous coat is not still well positioned to meet weaving will
Ask, such as Chinese public publication《Cotton textile technology》, in November, 2010 publication date, article name is maleic anhydride esterification propylene
The research of acid esters grafting starch, the document describes one kind using the acrylic ester grafted starch of maleic anhydride esterification to improve
The flexible method of serous coat, its weak point is that this starch-grafted technological process is long, takes more, high energy consumption, such as Chinese patent
Publication number CN102329437A, publication date 2012 year 01 month 25 days, entitled a kind of degradable starch composite pulp of innovation and creation
Material, this application case discloses the one kind using plant amylum, Ultra Tex 2, polyacrylic acid, starch and PVA compounding
Slurry, although its weak point is the toughness increase so that serous coat, is unable to fast degradation after PVA desizing, pollute environment.Such as
Chinese public publication《Cotton textile technology》, in July, 2012 publication date, article name is aqueous polyurethane to starch size
Modifying function, the document illustrates to add aqueous polyurethane component in starch size, can improve adhesion strength, and improve serous coat
Mechanical property, its weak point be plus improvement of the aqueous polyurethane to size film property be not well positioned to meet slurry still to yarn
Adhesiveness.China Patent Publication No. CN103923297A, publication date 2014 year 07 month 16 days, entitled one kind of innovation and creation
Aqueous polyurethane for toughness reinforcing starch serous coat and its preparation method and application, this application case discloses synthesis and is applied to starch slurry
Expect the polyurethane synthetic method of toughness reinforcing, solve after starch starching film forming occur serous coat it is hard crisp the characteristics of, due to having used poly- ammonia
Ester, improves the adhesion property of the mixed slurry to fiber of starch and polyurethane, and its deficiency is that disclosed polyurethane is mainly fitted
With pair as if acidified starch, and the technical scheme in starch and polyurethane mixed slurry adhesion property increase rate compared with
It is small.
The content of the invention
For above-mentioned problem, improved using ammonium dihydrogen phosphate and polyurethane it is an object of the invention to provide one kind
The method of sizing adhesive formula, to achieve these goals, its technical solution is：
A kind of utilization ammonium dihydrogen phosphate and polyurethane improve the method for sizing adhesive formula, including are formed sediment by phosphate
Sizing adhesive formula and stir and heat through switching on power that powder, acrylate and water component are constituted, heating-up temperature model
It is 95-100 DEG C to enclose, and the time of heating is 1 hour, wherein comprising two steps：The first step is stirring, and the time of stirring is 20 points
Clock；Second step is insulation, and the time of insulation is 40 minutes.Mixing speed scope is that the 200-400 revs/min of sizing being made uses viscous
Mixture, described method refers to add biphosphate in the sizing adhesive formula of phosphate ester starch, acrylate and water
Ammonium and polyurethane, wherein, phosphate ester starch quality is phosphate ester starch, acrylate, ammonium dihydrogen phosphate, polyurethane and the total matter of water
The 3-5% of amount, acrylate quality is the 3-5% of phosphate ester starch, acrylate, ammonium dihydrogen phosphate, polyurethane and water gross mass,
Ammonium dihydrogen phosphate quality is the 0.1-1% of phosphate ester starch, acrylate, ammonium dihydrogen phosphate, polyurethane and water gross mass, poly- ammonia
Ester quality is the 0.1-1% of phosphate ester starch, acrylate, ammonium dihydrogen phosphate, polyurethane and water gross mass.
Described polyurethane is biodegradable aqueous polyurethane.
As a result of above technical scheme, when the ammonium dihydrogen phosphate added in sizing adhesive is hydrolyzed, H2PO4 —Electricity
It is more than its hydrolysis degree from degree so that solution is in faintly acid, and NH4 +Hydrolysis is also in acidity.Under sour environment, starch divides greatly
Sub- glucoside bond activation can be reduced, and ionize the H for producing+Play a part of catalyst during the course of the reaction so that starch polymer chain holds
Easily it is broken, the viscosity of the sizing adhesive liquid for so being formed can be reduced, is conducive to improving oozing for sizing adhesive liquid
Permeability, and polyurethane has good adhesive property, and the fibres bond of yarn interior can get up.Sizing adhesive is in yarn
Distribution form on line is divided into two kinds, that is, be coated to and be impregnated with, and the rate of being impregnated with shows that sizing adhesive enters the energy of yarn interior
Power, covering rate reflects protective value of the sizing adhesive to yarn.Can through the sizing adhesive after this PROCESS FOR TREATMENT
In penetrating into yarn well, increase yarn in sizing process is impregnated with rate, so as to increased the cohesive force between fiber, improves
The strength and stretching property of guarantor of yarn.Simultaneously when sizing is declined with adhesive viscosities, with preferable mobility, in treatment yarn
During, the surface of yarn can be preferably wrapped in, so as to improve the covering rate of yarn.The energy in the mutual friction process of yarn
Preferably protect the surface hairiness of yarn.Therefore the technical program its it is critical only that cooperateing with using ammonium dihydrogen phosphate and polyurethane
Effect, ammonium dihydrogen phosphate mainly realizes the reduction of phosphate ester starch molecular weight and the reduction of viscosity, realizes sizing adhesive
More preferable mobility；Polyurethane is mainly realized linking viscous between phosphate ester starch and fiber and between polyurethane and fiber
Attached performance, because the ester bond in the ester bond in polyurethane and phosphate ester starch has extraordinary active force, so as to than it and singly
Pure ative starch or acidified starch has more preferable affinity, so that the technical program improves the principle of sizing adhesive not
Simple polyurethane is simply mixed with phosphate ester starch, but hydrogen bond action, the ammonium dihydrogen phosphate pair formed between utilizing ester bond
The effect that the effect of phosphate ester starch and phosphate ester starch and polyurethane are realized to common interaction of effect of fiber, most
The more preferable starch finishing effect of adhesive will be used on realizing eventually.
Sizing adhesive compared with traditional sizing technique under this technique strengthen while impregnability is improved its institute into
The adhesion of serous coat.And the ammonium dihydrogen phosphate of addition is nontoxic.
