Abstract

The invention discloses a high-strength light-proof weed mat and a production method thereof. The weed mat is manufactured by wefts and warps; the method comprises the steps of mixing, charging, extruding, drafting and drawing, sizing and rolling to prepare flat filaments, and then weaving to prepare the weed mat. The flat filaments which are prepared from a raw material formed by mixing polypropylene PP and high-density polyethylene HDPE at the weight ratio of (99-95):(5:1) are adopted as the wefts and warps, the sizes of the wefts and the warps are (10-14)*(10-14) per inch, and the gram weight is 90-130g / m<2>. The high-strength light-proof weed mat has the characteristics of being high in strength and light-proof, and is good in wefts and warps softness, high in strength and convenient to produce.

Description

technical field [0001] The invention relates to a weaving technique, in particular to a high-strength opaque grass-proof cloth and a production method thereof. Background technique [0002] Grass-proof cloth is a kind of ground covering material that is resistant to friction and aging after weaving polypropylene PP flat yarn with UV resistance. It is mainly used for ground weed control, drainage, and ground cleaning. At present, weed-proof cloth covering measures are widely used in grapes, fruit trees, etc., to inhibit the growth of weeds, maintain soil moisture, and reduce management labor costs. However, the plastic woven grass-proof cloth popular in the market basically has the phenomenon of light transmission and low strength. The light transmission causes weeds to germinate on the ground. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a high-strength, light-tight, high-strength opaque grass-proof cloth and...
