Comparative example
The invention provides a production process of an environment-friendly super-soft artificial leather fabric, which comprises the following steps:
s1, preparing a flexible composite layer: adding deer skin fabric into water for cleaning, heating the water to 40 ℃, soaking for 25 minutes, taking out the deer skin fabric, washing with 35 ℃ water for 15 minutes, drying the cleaned deer skin fabric by a fan, cutting the deer skin fabric into 30-80cm long, polishing the cut edge for flattening for later use, adding resin into deionized water, stirring uniformly, adding the later-used deer skin fabric for treatment for 30 minutes, taking out the deer skin fabric, and drying to obtain the deer skin fabric;
s2, preparing a skin surface treating agent: 80 parts of film-forming resin, 15 parts of compatilizer and 9 parts of curing agent;
wherein, the main components of the compatilizer are as follows: polyphenylene oxide and maleic anhydride, wherein the volume ratio of the polyphenylene oxide to the maleic anhydride is 100; the curing agent comprises the following main components: diethylenetriamine;
s3, adding the film-forming resin and the compatilizer in the step S2 into a container, heating to be completely molten, stirring for 10 minutes, then adding a curing agent, and continuously stirring for 6 minutes to obtain a skin surface treating agent for later use;
s4, the flexible composite layer prepared in the step S1 is flatly laid on a processing table, then the skin surface treating agent prepared in the step S3 is uniformly sprayed on the outer surface of the flexible composite layer, and the skin surface treating agent is subjected to uniform air drying treatment.
In this comparative example: the temperature for drying by a fan is 45 ℃, and the stirring speed is 300r/min.
In the comparative example, when the fabric is treated, the obtained semi-finished fabric obviously has certain peculiar smell and is higher in hardness, certain crease can exist in the production of a finished product, and the glossiness of the outer surface of the fabric is not ideal as in the embodiment.
The above embodiments are only some preferred embodiments of the present invention, and many alternative modifications and combinations of the above embodiments may be made by those skilled in the art based on the technical solution of the present invention and the related teachings of the above embodiments.
