RODENT REPELLENT FABRIC
FIELD OF THE INVENTION
The present invention relates to polymer-rodent repellant chemical composition and its manner of manufacture, and also to rodent repellent fabric coated with such polymer-rodent repellent composition in the manner such as to favour repelling of the rodents away from regions required to be protected and maintained free of rodent attack such as for rodent free grain storage .Importantly, polymer-rodent repellant chemical composition and the treated fabric using the same neither kills rodent nor is harmful to humans and is thus found to be safe and widely applicable for diverse end uses /applications.
BACKGROUND ART
Losses of stored agricultural products like grains, pulses, seeds and other food materials, etc., (hereinafter collectively called "the food materials"), at the farm and village level in developing countries due to rodent menace are not only an economic debilitating issue but have very serious health implications. While field crops are usually vulnerable to vertebrate pest damage during a short period of the growing season, stored food materials are vulnerable as long as they are held in storage. Most storage of harvested crops occur in open or by using different types of covers to protect from rain and other natural calamities or in silos made up of mud in the farm houses; these structures in the tropics and subtropics invariably are infested by one or more species of indigenous rodents. Stored food materials are regularly lost due to the consumption, contamination, wastage, and spoilage by the rodents.

The rodents that frequent food storages and live in close association with humans (commensal) in many parts of the tropics and subtropics in developing countries are also known to be the reservoirs and vectors of several human diseases. Among these are plague, murine typhus, Lassa fever, leptospirosis, several types of haemorrhage fevers, including Hantavirus, and salmonella infections. Roof rats, Norway rats, Polynesian rats, multi-mammate rats, and lesser bandicoot rats spread plague and murine typhus through their fleas. Lassa fever is known to be spread by the urine and faeces of the multi-mammate rat. Leptospirosis is a bacteria present in the urine of roof rats and Norway rats. Hantavirus is spread in the droppings and urine of Norway rats and other rodents (Peromyscus, Sigmodon, Microtus, Oligorzyomys species). Haemorrhage fevers are spread by the Calomys species of rodents.
Salmonella organisms are spread through the droppings of all the commensal rodents, house mice and rats alike. Prevention, reduction, or elimination of rodents from farm and village storage structures where these diseases are prevalent can reduce food materials losses as well as safeguard human health.
In conventional methods of storage of large quantity of grains for a long duration, the grain is stored in jute bags, woven baskets, or open cribs. None of these will keep rodents from the food materials. Wire mesh, metal and ceramic containers, or brick and concrete bins are needed to keep rodents out which are expensive and usually beyond the reach and pockets of subsistence and smallholding farmers.
Rodent repellents are well known in the contemporary art wherein rodents are eliminated by placing rodent baits around the farm structures. These rodent baits are made of anticoagulants and zinc phosphide, which are poisonous and can be harmful to children if swallowed or

touched. Other methods contemplated by the known art is the use of comparatively safer chemical sprays and granular deterrents which are again mixed with or sprayed into the food grains in the raw form, though these chemicals are safer than acute poisons they can be harmful to human, if not properly handled/removed during use and before use of the grains. The other problem is that anticoagulants are highly toxic in nature for rodents resulting in their death after consumption along with the grains, which is also the case in electronic repelling systems, ultrasonic and sonic equipments. The dead rodents create the menace of other diseases in Humans.
It is thus most desirable to provide rodent repellant composition which would favour overcoming the above discussed problems of conventional rodent repellants presently available in the art and which would on one hand favour effective rodent repellant characteristics and on the other hand would not be harmful/poisonous to rodents and humans and thus safe for diverse end uses/applications .

By way of such coating of the rodent repellant composition on the fabric, when the rodents approach the said fabrics which is used for covering stored grains, they are repelled by the pungent smell emanating from the fabric and hence the rodents are driven away. Such treated textile fabrics are thus induced to incorporate strong physical parameters and can be used to make tarpaulins and other storage materials. The treated textile fabrics can be adapted to

remain flexible, light in weight, easy to use, non-toxic to rodents, food materials and humans and have a very long life span.
The details of the invention, its object and advantages are explained hereunder in greater detail in relation to non-limiting accompanying figure and examples hereunder.
BRIEF DESCRIPTION OF THE ACCOMPANYING FIGURE
Figure 1 : illustrates schematically an embodiment of the method for carrying out fabric coating in accordance with the present invention.
Reference is invited to Figure 1 which illustrates by way of block diagram the process of manufacture of rodent repellant fabrics using the rodent repellent composition of the invention. As represented in the said figure the fabric is first taken which is coated with the polymer / rodent repellent chemical composition to thereby obtain the treated fabric. The treated fabric is used for fabrication of tarpaulins or other storage materials having rodent repellent characteristics for variety of applications including covering or storage areas.
The manner of coating the fabric with the rodent repellant composition of the invention is explained hereunder in greater detail in relation to Example I:
EXAMPLE 1
The chemical composition of the rodent repellant in accordance with the invention was obtained for coating of polyester fabric involving a first coat formulation and a second coat formulation as provided hereunder in Table 1.


*PHR - PART'S HUNDRED RESIN
The procedure followed was as detailed hereunder:
The mixed paste is first coated as a prime coat on the surface of the fabric to make the fabric surface smoother. This coating is on both side of the fabric. The coating weight is varying as per the requirement and varying between 50gsm to 300 gsm. After this coating, the RR chemical mixed paste is coated either on both the side of the fabric or on one side and either

by separate operation or in single operation. The quantities can be changed as per the requirements of different properties and characteristics of the fabrics. Any of the ingredients can vary from any quantity to any quantity. After coating, it is cured at 150 to 200^ C temperature in the continuous drying oven and then the fabric is taken to fabrication department for fabricating the Tarpaulin / Tents of different sizes.
The rodent repellant characteristics of the coated fabric was next determined.lt was found that the fabric did not allow the rodents to come near this and if the material (Grains / Paddis of Seals) are covered by this fabric, will protect the material from the rodants and minimize or eliminate the loss. This is very useful, where the rodants population is high and the attach of the rodent on material is predominant.
Further, the rodent repellant composition coated polyester and nylon fabrics obtained using the composition as above were again tested extensively in the field to identify its rodent repellant characteristics. The tests carried out for the purpose are detailed hereunder in Examples II to IV.
Example-n
The polyester and nylon fabric coated on both the sides with the above composition with Rodent Repellant chemical was fabricated in the form of tent. In side the tent, grain bags (Wheat) was kept. Along with this, one more tent with our QAA (Quaternary Ammonium Adduct) in the above composition but rests of the ingredients were same was made. In this tent also the wheat bags inside was kept. For continuous 15 days of observation, it was found that the Rodents started cutting and destroyed the tent and grains of the tent which was not

having QAA in the composition, urther the same results were observed the same for next 2 months. The rodents were not going near the QAA Tent due to its peculiar smell.
Example -HI
The seeds were covered in a oil mill, where the Rodent attack was very severe. After covering the seeds with the tarpaulin having QAA composition of the invention it was possible to keep the Rats away.
The same type of tests were carried out at different places, with different type of grains and found no variation in the results. Example -IV
For the purpose of this test, the wall was made of the fabric in 2 cages. One cage was having QAA Composition in accordance with the invention and other was without QAA. On one side of this wall. Rodents were kept for 15 days and other side some eatable. Rodents started attacking on the fabric, which was without QAA composition and weight loss due to this was very high, where as in case of QAA fabric of the invention, it was negligible.
It would be clearly apparent from the above example that the above coated fabrics involving the coating of the rodent repellant formulations is adapted to favour repelling of rodents without killing of rodents or causing harm to humans and animals by providing for the
