Embodiment 1

[0039] see figure 1 , a preparation method of degradable non-woven fabric, comprising the steps of:

[0040] S1: Material selection: select polyester fiber as a low melting point polymer, select modified polyester fiber as a high melting point polymer, and prepare a resin solution;

[0041] S2: Fiber carding: the low-melting point polymer and the high-melting point polymer are sequentially carded into a fiber web by a carding machine, and the carded polyester fiber web is evenly laid inside the mold;

[0042] S3: spraying: applying the prepared resin solution to the polyester fiber net in the mold through a spraying device;

[0043] S4: Infiltration: After fully infiltrating, remove the frame of the mold, and put the mixed polyester fiber net into the flat vulcanizing machine;

[0044] S5: Press forming: the temperature and pressure provided by the flat vulcanizer act on the polyester fiber net to press the non-woven fabric, and put the pressed non-woven fabric into an oven ...

Abstract

The invention discloses a preparation method and equipment of a degradable non-woven fabric, and belongs to the technical field of non-woven fabrics, the preparation method of the degradable non-woven fabric comprises the following steps: S1, material selection: selecting polyester fibers as a low-melting-point polymer, selecting modified polyester fibers as a high-melting-point polymer, and preparing a resin solution; s2, fiber carding, wherein low-melting-point polymers and high-melting-point polymers are sequentially carded into fiber nets through a carding machine, and the carded polyester fiber nets are evenly laid into a mold; s3, spraying, wherein the prepared resin solution is applied to a polyester fiber net in the mold through a spraying device; s4, infiltrating: after full infiltrating, taking down the frame of the mold, and putting the mixed polyester fiber net into a press vulcanizer, so that melt blending can be performed, the performance of each polymer component can be balanced, the advantages can be made up, the weakness of each single polymer component can be eliminated, and the polymer material with excellent comprehensive performance can be obtained.

Description

technical field [0001] The invention relates to the technical field of non-woven fabrics, in particular to a preparation method and equipment for degradable non-woven fabrics. Background technique [0002] The application publication number is (CN108893979A) a kind of preparation method of degradable non-woven fabric, by limiting the mass fraction of polyvinyl alcohol and guar gum aqueous solution, the ratio of the two, spinning after mixing, the fiber obtained by spinning has Good toughness and tensile properties; the intermediate fabric is obtained by spunlace, and then the intermediate fabric is placed in glutaraldehyde solution and sodium borate aqueous solution to vibrate and cross-link, so that the fibers of the intermediate fabric are cross-linked into a complex network structure. Greatly increase the toughness and tensile properties of the present invention; suitable shaking temperature and time can promote sufficient crosslinking and further increase the mechanical ...
