Description
Technical field
The present invention relates to textile technology field, more particularly, to a kind of paste compound for yarn or textile fibre sizing
And its preparation method and application.
Background technology
Traditional coating dyeing is that coating is made dispersion liquid, makes fabric homogeneous band liquid by padding, then through high-temperature process,
By means of the effect of binding agent, fabric forms layer of transparent and tough and tensile resin film, thus by paint machine ground set
On fiber, coating itself does not have affinity to fiber.
Coating, as a kind of pigment, is widely used for a long time on stamp, in recent years, because printing and dyeing assistant is (as glued
Mixture) performance continuous improvement, extend the range of application of coating, so that pigment dyeing technique is developed rapidly.Coating contaminates
Color also has weak point, and such as mechanical set determines its crock fastness, especially washes that fastness is not high by rubbing with the hands, and after dye, fabric feeling is sent out
Hard etc..
The quality of Pigment Dyeing Quality, it is critical only that the selection of binding agent.Pigment dyeing binding agent, performance requirement is for example good
Good film property and stability, suitable adhesion strength, higher chemically-resistant agent stability, epithelium water white transparency, high resilience
With toughness, unsuitable aging and yellowing etc..Fastness and feel are required higher, and roll not easy to stick etc..Adhesive agent emulsion does not contain
N- methylol, without APEO, energy-conserving and environment-protective.
In recent years, it is devoted to both at home and abroad seeking new green type environment-friendly adhesive, domestic and international patent has prepared a kind of ring
Guarantor's type acrylic ester coating printing adhesive, but fabric feeling the problems such as harden after dye can not be solved, domestic patent system also
For having gone out a kind of environment protection type microemulsion interpenetrating network pigment resin printing adhesive agent, solve the problems such as feel, environmental protection, but can not solve
After dye the problems such as fabric hydrophilic.
Pigment printing is by mean of binding agent and coating is adhered to the printing technology that fiber surface to obtain desirable pattern, existing
It is widely used in various yarns or textile fabric, have that process is simple, lovely luster, decorative pattern be clear, energy- and time-economizing, the three wastes are few etc.
Advantage.Most printing adhesives in the market all containing a certain amount of N- hydroxyacrylamide cross-linking monomer, baking and
A large amount of free formaldehydes can be discharged it is impossible to meet the requirement of high weight yarn or textile fabric and clothing, serious shadow in storage process
Ring and limit the development of China's rag trade.Additionally, alkylphenol polyoxyethylene (APEO) is because safety is not high and biodegradation
Property the potential hazard that environment is existed such as difference widely studied and proved, some countries of Europe just formulated method from 1976
Its production of restrictions system and use.And European Union's also use, circulation and discharge to APEO on June 18th, 2003 formal promulgation regulation
Make clear and definite restriction and specified, especially stricter to the limitation of the APEO in yarn or textile fabric and clothing.
Therefore, how to solve that fabric feeling hardens, crock fastness is poor, it is not high to wash fastness by rubbing with the hands, fabric hardness is higher, viscous after dye
Put forth effort difference and the technical problem of environmental pollution has become the current focus studied.
Content of the invention
For solving the problems of the prior art, the invention provides a kind of slurry group for yarn or textile fibre sizing
Compound and its preparation method and application.The present invention provide paste compound after for coated yarns or textile fabric, its energy
Enough solve that fabric feeling hardens, crock fastness is poor, it is not high to wash fastness by rubbing with the hands, contaminate after fabric hardness is higher, adhesion strength is poor and to ring
The technical problem of border pollution, thus it is excellent to reach crock fastness, it is high especially to wash fastness by rubbing with the hands, after after dye, fabric feeling feels like jelly, contaminates
