Summary of the invention
The object of the present invention is to provide a kind of production method of environmental protection type nonwoven cloth, product environmental protection is formaldehydeless and physical property stable, and technique is simple, with low cost.
For achieving the above object, technical scheme of the present invention is the production method of a kind of environmental protection type nonwoven cloth of design, comprises the steps:
1) raw fiber enters carding machine, uniformly fiber is unclamped, and according to required weight, be dispersed in uniformly on carding machine outlet transport tape in the process of comb and parallel cotton fibers prior to spinning, becomes web;
2) prepare adhesive: in reactor, add and in 100-120 parts by mass acrylic resin, add 3-5 parts by mass urea derivative ethoxy acrylamide, reaction temperature is arranged on 93-95 ℃, stir, and interpolation accounts for the emulsifying agent of pre-emulsification reactant liquor part by weight 2.5-3/1000, add again initator and residual emulsifier, polymerization reaction take place, during reaction, temperature constant is at 93-95 ℃, and stir mixing speed 140rpm/min;
3) on web, be coated with and spill through binder liq;
4) web is sent into baking oven sizing and be dried, become finished product.
Advantage of the present invention and beneficial effect are: a kind of production method of environmental protection type nonwoven cloth is provided, and product environmental protection is formaldehydeless and physical property stable, and technique is simple, with low cost.
The specific embodiment
Below in conjunction with embodiment, the specific embodiment of the present invention is further described.Following examples are only for technical scheme of the present invention is more clearly described, and can not limit the scope of the invention with this.
The concrete technical scheme of implementing of the present invention is:
Embodiment 1
