Weeding moisturizing material, weeding moisturizing cloth and preparation method

Abstract

The invention discloses a weeding moisturizing material, a weeding moisturizing cloth and a preparation method. A weed killer is loaded on a non-woven fabric with polyethylene terephthalate (PET) as a raw material and composited with a super absorbent resin to form the weeding moisturizing material; according to the weeding moisturizing cloth, a bottom layer is a non-woven geotextile fabric, an upper layer is the non-woven fabric which is loaded with the weed killer and uses the PET as the raw material, a middle layer is the super absorbent resin, and the three layers are punctured and composited to form the weeding moisturizing cloth; and the preparation method of the weeding moisturizing cloth includes that the PET is spun into as-spun fibers, the obtained as-spun fibers are drafted and subjected to air flow spinning jet to form a fiber mesh, the obtainer fiber mesh is subjected to punching strengthening, an aqueous solution of weed killer is sprayed on the surface of the fiber mesh, the fiber mesh is dried to obtain the non-woven fabric which is loaded with the weed killer and uses the PET as the raw material, and the obtained three materials of the non-woven fabric, the super absorbent resin and the non-woven geotextile fabric are punctured and composited to form the weeding moisturizing cloth. The weeding moisturizing material and the weeding moisturizing cloth have the advantages that the weeding and moisturizing effects are good, the seedling raising costs are lowered, the weeding moisturizing material and the weeding moisturizing cloth are environment-friendly, and water and soil can be conserved. The preparation method of the weeding moisturizing cloth is simple, low in costs and capable of achieving massive industrialized production.

Description

technical field [0001] The invention relates to a weeding and moisturizing material, a weeding and moisturizing cloth and a preparation method, and belongs to the field of new composite materials. technical background [0002] According to scientific surveys, manual weeding accounts for more than 30% of the total labor in general orchard forest farms, and the tenacious vitality of weeds and shrubs and their strong adaptability to adverse climatic conditions require manual weeding or spraying herbicides every 2 months. ~4 times, resulting in high labor costs and soil erosion. At the same time, herbicides cause serious pollution to soil and air. In the past two years, the southwestern region has experienced continuous drought, causing heavy losses to commercial crops. Facing the severe situation, awareness of water conservation, environmental protection, and scientific use of energy needs to be strengthened urgently. It has become a consensus to develop new environmentally fr...
