Embodiment 1

[0049] like figure 1 , the fresh-keeping pad of this embodiment is obtained by pressing spunbonded non-woven fabric 1, two layers of spunlace composite fiber layer 2 and plastic film 3 from top to bottom, and the preparation raw materials of spunlace composite fiber layer include a mass ratio of 2:1 Viscose fiber and bamboo fiber, areal density 250g / m 2 , the spunlace composite fiber layer is prepared by the pearl pattern spunlace process, and the functional material 4 is filled between the two spunlace composite fiber layers, namely water-absorbent resin and chitosan.

[0050] This embodiment adopts the combination of drum type spunlace technology and pearl texture design. The drum sleeve has a concave circular texture, which forms a pearl texture. The inside of the circular texture is provided with uniform holes. The opening ratio of the drum sleeve is 20%. The diameter of the circular texture is 5 mm, the depth of the depression is 0.5 mm, the distance between adjacent ci...

Embodiment 2

[0059] In the fresh-keeping pad of this example, the raw materials for the preparation of the spunlace composite fiber layer include viscose fiber and bamboo fiber with a mass ratio of 3:1, and other structures and preparation methods are the same as in Example 1.

Embodiment 3

[0061] In the fresh-keeping pad of this example, the raw materials for the preparation of the spunlace composite fiber layer include viscose fiber and bamboo fiber with a mass ratio of 5:1, and other structures and preparation methods are the same as in Example 1.

Abstract

The invention relates to a fresh-keeping pad containing spunlaced composite fiber layers and a preparation method thereof. The fresh-keeping pad is obtained by pressing spun-bonded non-woven fabric, two layers of spunlaced composite fiber layers, and a plastic film, wherein the raw materials for the preparation of the spunlaced composite fiber layers comprise viscose fiber and bamboo fiber with amass ratio of (1-5): 1, the spunlaced composite fiber layers are obtained by preparation with pearl grain spunlaced process, and water absorbing material and a preservative are filled between the twolayers of spunlaced composite fiber layers. The preparation method comprises the steps of opening and mixing, carding and laying, spunlace reinforcement, pressing, filling, trimming and winding. The fresh-keeping pad has the advantages of high strength, strong water absorption, prolonged food fresh-keeping time, safety and environmental protection.

Description

technical field [0001] The invention belongs to the technical field of food preservation, and in particular relates to a fresh-keeping mat containing a spunlace composite fiber layer and a preparation method thereof. Background technique [0002] With the development of science and technology and the improvement of people's living standards, people have put forward higher and higher requirements for the richness and safety of their daily diet. Fresh food, meat, fruits and vegetables and other ingredients in modern supermarkets are individually packaged, and more and more people choose to buy ingredients that have been cut and packaged, which is not only convenient to buy, but also beautiful and hygienic. This puts forward new requirements for the packaging of ingredients. While keeping the freshness and delicious taste of the ingredients as much as possible, the shelf life of the ingredients should be extended as much as possible. At present, the commonly used packaging in ...
