A Review on Use of Polypropylene Non-Woven Fabric for Crop Covering with Spun Bond technology in Agro-Textiles Chintanika J. Sachinwala1, Prakash A. Khatwani2 1 M.E (Textile Engineering), L D College of Engineering, Ahmedabad, Gujarat 2 Professor and Dean (R & D), Sarvajanik College of Engineering & Technology, Surat, Gujarat sl.chintanika@gmail.com Abstract: Agro textiles are an important part of technical textiles. Spun bond technology is a emerging area in order to work in Agro-textiles. Also there are various fibers or non woven fabrics manufactured from this technology. Polypropylene is a material widely used for agro textiles covering vast products from covers, nets and bags. The paper focuses on the review of various works done in…show more content…
The essential properties required in agro textiles are strength, elongation, stiffness, resistance to sunlight and resistance to toxic environments. All these properties help with growth and harvesting of crops. Agro Textile products (shade netting and thermal screens) enable a saving of 40% on energy used for heating green house. Agro textiles are beneficial and are known for their excellent properties like good strength, elongation, resistance to sunlight and stiffness. Also they protect from the UV radiations from sunlight. All these properties lead to good harvesting and increase production of crops. Various types of products like shade nets, covers, bags, mud covers, fishing nets are used in Agro textiles. There are two types of fibers used in Agro textiles. They include Manmade fibers and Natural Fibers. Polypropylene and polyethylene come under manmade fibers while jute and wool come under natural fibers. Crop covers help us to have good harvesting and a considerable increase for production of crops. Crop covers protect against cold, frost, rain and insects. Crop covering generate an outstanding Micro Organism (MO) for seed germination and seeding growth. Its positioned over a huge area of…show more content…
And it is also a major synthetic material for textile as well as composite industry. A important quality of PP is its capability that it is used in wide fibrous forms. Various applications like automobiles, medical as well as geo textiles are summarized [1]. Creep resistance is improved by making the material light, by changing the process parameters or by adding additives to the material. A model is developed for long-range prediction of creep which shows that a very small deformation is found for high molecular weight of PP with a narrow distribution and with high molecular orientation [2]. Polymer blends enhance the fiber properties by making Biconstituent fibers having combination of Nylon 6 with Nylon 66, PP with PET and block copolyester [3]. A series of sheath/core composite polypropylene fibers with different phase change material (PCM) are studied using SEM, DSC and temperature sensors. The ability of the fabric is affected by PCM, sheath/core ratio and temperature [4]. PP covers were used for early potato crops which increased the productivity and harvest time of crops. This was possible as weight of PP was 2.5 times less than weight of perforated polyethylene film. Harvest period increased by 2-3 weeks [5]. From Figure 1 it can be deduced that temperatures and PP fibers improve the growth and harvesting of the potato
