Title (EN) ECO-FRIENDLY BIODEGRADABLE MULCHING MATERIAL WITH IMPROVED TENSILE STRENGTH
(FR) MATÉRIAU DE PAILLAGE BIODÉGRADABLE RESPECTUEUX DE L'ENVIRONNEMENT PRÉSENTANT UNE RÉSISTANCE À LA TRACTION AMÉLIORÉE

Abstract:
(EN) The present invention relates to an eco-friendly biodegradable mulching material with improved tensile strength, the mulching material solving a problem of weak strength (tensile strength) of a conventional mulching material made of a vinyl film or biodegradable film, wherein the mulching material comprises: (A) 1 part by weight of a natural adhesive containing gelatin, PVA, and a hibiscus root extract at a weight ratio of 3-7 : 10-15 : 0.2-1.5; and (B) 12-16 parts by weight of a fibrous part containing natural cotton, a fiber raw material of natural rayon, natural hemp, or a mixture thereof, and a natural fiber extracted from one or more selected from a coconut shell and an almond shell or sugar cane at a weight ratio of 15-29 : 12-22 : 7-13. According to the present invention as above, it is possible to provide an eco-friendly biodegradable mulching material, which has higher tensile strength than a conventional biodegradable mulching material and thus can be handled in the same manner as a vinyl film mulching material in the production process or at a site of use while having low production costs.
(FR) La présente invention concerne un matériau de paillage biodégradable respectueux de l'environnement présentant une résistance à la traction améliorée, ce matériau de paillage résolvant le problème de faible résistance (résistance à la traction) d'un matériau de paillage classique constitué d'un film vinylique ou d'un film biodégradable, le matériau de paillage comprenant : (A) 1 partie en poids d'un adhésif naturel contenant de la gélatine, du PVA et un extrait de racine d'hibiscus qui sont présents selon un rapport pondéral de 3-7/10-15/0,2-1,5; et (B) 12 à 16 parties en poids d'une partie fibreuse contenant du coton naturel, une matière première fibreuse à base de rayonne naturelle, de chanvre naturel ou d'un mélange de ceux-ci, et une fibre naturelle extraite d'une ou de plusieurs matières choisies parmi la coque de noix de coco et l'écorce d'amande ou la canne à sucre qui sont présentes selon un rapport pondéral de 15-29/12-22/7-13. Selon la présente invention et comme indiqué plus haut, il est donc possible de fournir un matériau de paillage biodégradable respectueux de l'environnement, qui présente une résistance à la traction supérieure à celle d'un matériau de paillage biodégradable classique et peut ainsi être manipulé de la même manière qu'un matériau de paillage formé d'un film vinylique lors du processus de production ou au niveau d'un site d'utilisation, tout en présentant de faibles coûts de production.
(KO) 본 발명은 종래 비닐 필름 또는 생분해성 필름을 소재로 한 멀칭재의 약한 강도(인장력) 문제점을 해소한 친환경 자연분해 멀칭재에 관한 것으로서, (A) 젤라틴 : PVA : 황촉규추출물을 3~7 : 10~15 : 0.2~1.5의 중량비로 포함하는 천연접착제 1중량부; 및 (B) 천연솜 : 천연레이온, 천연마 또는 그들의 혼합물인 섬유원료 : 코코넛피 및 아몬드피 또는 사탕수수 중에서 선택되는 하나 또는 둘 이상으로부터 추출한 천연섬유질을 15~29 : 12~22 : 7~13의 중량비로 포함하는 섬유질부 12~16중량부;를 포함하는 인장강도가 개선된 친환경 자연분해 멀칭재인 것을 특징으로 한다. 이상과 같은 본 발명에 의하면, 종래 생분해성 멀칭재보다 우수한 인장력을 가지게 되어 생산원가가 낮으면서도 생산공정이나 사용현장에서 비닐 필름 멀칭재와 동일한 방식으로 취급할 수 있는 친환경 자연분해 멀칭재의 제공이 가능해진다.
