Abstract

The invention discloses a degradable non-woven fabric for mulches. The degradable non-woven fabric is prepared from, by mass, 30-40 parts of plant fibers, 1-2 parts of penetrant, 7-9 parts of elastomer, 10-20 parts of collagen fibers, 1-3 parts of calcium carbonate, 30-50 parts of corn starch and 2-4 parts of gelatin. According to the degradable non-woven fabric for the mulches, a production method is simple, the materials can be completely degraded, and the environment is not polluted.

Description

technical field [0001] The invention belongs to the technical field of non-woven fabrics, and in particular relates to a degradable non-woven fabric for mulching. Background technique [0002] In the process of planting many crops, in order to obtain a better growth environment, mulch is used. At present, the known mulch is mainly made of plastic, which is widely used in agriculture because of its low price. With the continuous expansion and the increase in the number of years of use, the residual plastic mulch in the farmland continues to accumulate, which is non-degradable, destroys the soil environment for crop growth, and begins to have a negative impact. [0003] Non-woven fabrics are composed of directional or random fibers. They are a new generation of environmentally friendly materials. They are moisture-proof, breathable, flexible, light in weight, non-combustible, easy to decompose, non-toxic and non-irritating, rich in color, low in price, and recyclable. Feature...
