  • the composition contains a water soluble copper capable of producing ions in water, which is dispersed in an elastomer in which the copper salt is insoluble.
  • bags for growing plants and trees are used, which are filled with soil and disposed on wire nettings which facilitate their transportation.
  • Other bags are made of non-woven fabric and chemically untreated.
  • Plastic containers are also used for growing plants.
  • the roots can pass through the bags and are proved to be destroyed during transplantation.
  • the roots can also grow helically within the bags. In such a case, the roots are also destroyed during soil transplantation, and to that extent, plant growth is slowed down.
  • the invention is directed to a fabric for growing plants, containing an insoluble copper product bounded to said fabric with a water insoluble polymeric binder.
  • the invention is directed to a water insoluble textile fabric for use in growing plants, comprising a water insoluble polymeric binder and a water insoluble copper product, the copper product being dispersed in the binder and the binder being bounded to said fabric for retaining and confining the copper product to the water insoluble textile fabric, whereby the textile fabric stops the growth of undesirable rootlets or radicles which comes in contact thereto.

  • This latex is mixed with the water insoluble copper product.
  • This copper product may be copper hydroxide or, more preferably, copper carbonate in powder or dispersed form.
  • the amount of carbonate that is used is preferably selected to obtain a textile fabric containing from 5 to 100 grams per square meter, preferably 15 to 30 grams per square meter, of copper carbonate.
  • the mixture of the copper carbonate with the latex is preferably carried out in a mixer having a high friction coefficient. Once a good dispersion of the copper carbonate in the polymeric latex is obtained, the mixture is used to impregnate the fabric.

Abstract

Tissu de textile contenant un sel de cuivre insoluble, utilisé pour contrôler la croissance des racines d'une plante. Le tissu comprend un liant polymère insoluble dans l'eau, tel qu'un latex, et un produit de cuivre insoluble dans l'eau, de préférence du carbonate de cuivre. Le produit de cuivre est introduit sous forme de dispersion dans le liant qui retient et confine le produit de cuivre dans le tissu de textile. Le tissu peut être utilisé pour interrompre la croissance de petites racines ou de radicelles indésirables qui entrent en contact avec lui.
