Description
Technical field
The present invention relates to the processing aid in a kind of textile printing and dyeing, specifically a kind of water resistance environmental-friendly stiffening agent and its system
Preparation Method.
Background technology
At present, when the processing of the fabrics such as cloth, wall paper, suitcase cloth is played in such as casement, directly, fabric needs to have after machining
There is certain stiffness.Especially warp knit type fabric, the stiffness after the processing of its fabric have strict requirements.Stiffening agent is should
With quite varied textile auxiliary, it makes fabric have stiffening characteristic by assigning fabric elasticity and sense of fullness.Pass
The stiffening agent of system mainly has four kinds of polyacrylate, Lauxite, polyvinyl acetate and vinegar propylene copolymer, but above-mentioned stiffening agent
It is respectively provided with itself unsurmountable technological deficiency.The stiffening effect of polyacrylate is good, but its durability extreme difference on fabric,
And have it is heated it is tacky, be cooled the defects of becoming fragile；Lauxite is stiffening to work well, but its content of formaldehyde after processing is high, with
The continuous reinforcement of people's environmental consciousness and the progressively constraint of related environmental regulation, it can not meet that increasingly strict fabric adds
Work demand；Polyvinyl acetate is the most long hard finishing auxiliary agent of application time, its biggest advantage is that formaldehyde is free of, but its is hard
Very property is poor, and has the shortcomings that water resistance, weatherability difference；The stiffening effect of vinegar propylene copolymer is good and is free of formaldehyde, so it should
With also more and more extensive, but its wash durability extreme difference after being arranged to fabric, it is mainly shown as fabric hard finishing
Moisture regain softens afterwards, and hardness declines obvious after washing.
Based on drawbacks described above, the various modes for once occurring stiffening agent in yarn fabric processing aid industry are improved.Such as in public affairs
The number of opening is in CN1524911A Chinese patent literature, is disclosed a kind of more for timber, paper, fiberboard, foamed plastics etc.
The synthesis of the polyvinyl acetate emulsion of the bonding of Porous materials and preparation method.Be primary raw material with vinegar third, compound nertralizer,
Emulsion is aggregated into the presence of the materials such as initiator, surfactant.But above-mentioned emulsion has the shortcomings that solid content is relatively low, and should
Emulsion is directed to the adhesive property of material, thus cannot be used for the hard finishing of fabric.
And in Publication No. CN102433750B Chinese patent literature, then disclose one kind and be applied to fabric hard finishing
Environmental-friendly stiffening agent and preparation method, with vinyl acetate, acrylate etc. for primary raw material, aggregated into the presence of initiator
Emulsion.The solid content of the emulsion can reach 50% or so, and it is preferable that effect is endured with all one's will in textile finishing.But its wash durability still compared with
Difference, the situation that moisture regain softens equally occurs after fabric hard finishing, its hardness declines fairly obvious after especially washing.
Therefore, how to develop it is a kind of there is excellent wash durability, may conform to the cloth hard finishing agent of ecological requirements again is
One of significant technology issues of yarn fabric processing aid industry at present.
The content of the invention
