Embodiment 1

[0051] To prepare the weeding wet cloth:

[0052] 1. Textile fiber web:

[0053] The PET chips are sent to the fluidized bed for pre-crystallization through the conveying device. The temperature is controlled at 145~160°C. The pre-crystallized PET chips are sent to the drying tower for further drying. The drying temperature is controlled at 165~175°C so that the final moisture content is less than 30ppm, reaching Spinning requirements: the dried slices are fed into the extruder to be melted and mixed with the added black anti-aging masterbatch, and sent to the spinning box under a pressure of 6 kg, and the spinning temperature is controlled at 275~285°C. Through the spinning metering pump and spinning components, the as-spun silk with a diameter of 0.3-0.5mm is produced, and the as-spun silk is drawn 4000-5000 times to make the silk reach a fineness of 4-12dtx, and then it is evenly formed into a net by air-jet spinning;

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...
