Embodiment 1

[0079]96% by mass of a propylene homopolymer (PP1) having an MFR of 20 g / 10 minutes and a Mw / Mn of 4.2, high-density polyethylene (PE1, manufactured by Prime Polymer Co., Ltd., product name "HI-ZEX HZ2200J", MFR= 5g / 10 minutes, density 0.964g / cm 3 ) 4% by mass, melt-spun at 230°C so that the obtained fibers were deposited on the collection surface to obtain fibers with a diameter of 40 μm and a mesh weight of 20 g / m 2 The spunbonded nonwoven fabric is used as a covering material for agriculture. The obtained covering material for agriculture was evaluated by the method described above. The results are shown in Table 1.

Embodiment 2、3

[0081] Except having used the spun-bonded nonwoven fabric which has the composition ratio, fiber diameter, and mesh weight described in Table 1, it carried out similarly to Example 1, and obtained the covering material for agriculture.

[0082] The obtained covering material for agriculture was evaluated by the method described above. The results are shown in Table 1.

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 comprising a nonwoven fabric of a propylene-based polymer composition, and in particular to an agricultural covering material suitable for durability and excellent growth and development of crops in open-air cultivation, shed cultivation, greenhouse cultivation, direct covering ( Covering material for agriculture and method for producing the same. Background technique [0002] In order to protect crops against changes in the external environment and help them grow and develop, agricultural mulching materials are widely used. Covering materials for agriculture can be broadly classified into films and nonwoven fabrics, and are used according to their respective characteristics. [0003] Agricultural covering materials made of films have no or low air permeability, but have high barrier properties and high transparency (or high light-shielding properties). Uses such as suppressing the gr...
