Abstract

The present invention addresses the problem of developing a covering material for agricultural use, which has superior durability and an excellent property of enabling the growth of agricultural crops such as vegetables. The present invention provides: a covering material for agricultural use, which comprises a non-woven fabric produced from a propylene polymer composition comprising 90 to 98 mass% of a propylene polymer (A) and 10 to 2 mass% of an ethylene polymer (B) [wherein (A)+(B) = 100 mass%]; and a method for producing the covering material.

Description

Technical field [0001] The present invention relates to an agricultural covering material of a non-woven fabric containing a propylene-based polymer composition, in particular to an open-air cultivation, arched shed cultivation, greenhouse cultivation and direct covering ( Full coverage) agricultural coating materials and manufacturing methods thereof. Background technique [0002] In order to protect crops against changes in the external environment and help their growth and development, agricultural coating materials are widely used. Agricultural coating materials can be roughly classified into films and non-woven fabrics, and they are used according to their characteristics. [0003] The agricultural coating material made of film has no or low air permeability, but has high barrier properties and high transparency (or high light-shielding), for example, it is used for heat preservation in severe winter (greenhouse cultivation), and prevents rainwater penetration of fruits, It ...
