Embodiment 1

[0046] to combine figure 1 As shown, the present embodiment provides a kind of production process of seaweed polysaccharide cellulose non-woven fabric, which comprises the following steps:

[0047] Step S1, raw material extraction

[0048] In this step, alginate is extracted from seaweed;

[0049] Step S2, preparing spinning dope

[0050] In this step, first prepare an alginate solution with an alginate weight percentage of 80%-95%, then add 10 parts by weight of synthetic resin to every 100 parts by weight of the alginate solution and adjust the pH to neutral to obtain spinning silk stock solution;

[0051] Step S3, preparing seaweed fiber

[0052] In this step, the spinning stock solution is prepared into seaweed fiber by wet spinning process;

[0053] Step S4, preparing non-woven fabric

[0054] In this step, seaweed fibers are used to prepare non-woven fabrics.

[0055] Through steps S1-S4 in this embodiment, due to the addition of synthetic resins, the viscosity an...

Abstract

The invention relates to the technical field of non-woven fabric production, in particular to a production process of an algal polysaccharide cellulose non-woven fabric. The process comprises the following steps of S1, extracting raw materials; S2, preparing a spinning solution; S3, preparing alginate fibers; and S4, preparing the non-woven fabric. According to the method, the viscosity and strength of the alginate fibers can be better improved due to the addition of synthetic resin in the steps S1-S4, so that the filamentation of the spinning solution can be better facilitated, and the strength of the prepared non-woven fabric can be better improved.
