Dear Mr. James, Greetings!!! Please find herewith specifications for Non-woven Geo Products: 1. Geo textile bags of type “A” (1.03x0.70M) made of geo-textile non-woven fabric sheets of 400GSM etc. Manufactured from 100% virgin polypropylene (PP) fibre with maximum properties as (i) Tensile strength >12.4 KN m (ii) Mass > 400.00 GM m2 (iii) CBR Puncture strength > 1550 N m2 (iv)Elongation @ break (warp) >54% (v) Elongation @ break (weft) >54% (vi) Abrasion > 70% (vii) UV resistance @ 500 hours > 70% (viii) AOS 1.25 (x)Trapezoidal Tear Strength < 340 N (xi) Permeability = 2.00 x 10 m sec (xii) Seam Strength = 80% of geotextile strength. Stitching of bags should be Ring spun yarn stitches with 2500 -3000 denier double n with overlap with stiches along the edge @ 15 stiches per 100mm. (Bags are to be supplied of 100 or part in a bundle, properly packed with name of manufacturer and batch is to be marked on each bag with “WRD Govt of Assam” to be printed on each bag and mentioning properly the GSM and type of geo bag polymer. Test certificate from approved NABL accredited and ISO certified laboratory should invariably be submitted with each batch of materials. Total Requirement is for 10,00,000 (Ten Lacs) Bags. 2. Supply of Geo Bags Type-B (Size 2.00m x 1.50m)( pillow Type) made of composite layers of geo-textile as per specifications below : Woven Geo-textile for the outer cover. The woven geo textile is woven with UV resistant slit film tape fibre with MAVR values of the following properties. Geo-textile used to manufacture geo-textile bags should have high mechanical properties for enhanced durability along with enhanced puncture, abrasion and U.V. resistance characteristics. Geo-textile should be inert to biological degradation and resistant to naturally encountered chemicals, alkalis, and acids. Weight (ISO-9864 ASTMD 5261) ≥300 Gms Sqm. Tensile strength (MD) (ASTMD 4595) = ≥35 kN m Tensile strength (CD) (ASTMD 4595) = ≥35 kN m Tensile Elongation (ASTMD 4595) = ≥5% & ≤30% Grab Elongation (ASTMD 4632) = ≥5% & ≤30% Tensile strength (ASTMD 4632) = 1.5 KN UV resistance (ASTMD 4355) = 70% 500 hrsNon-woven Geo-textile for the inner layer It is needle punched non-woven geo-textile made of 100% polypropylene staple fibers which are formed into a random network for dimensional stability. It should resist UV degradation, rotting and alkalis. Weight (ISO-9864 ASTMD 5261) ≥250 Gms Sqm. Tensile strength (MD) (ASTMD 4595) = ≥12 kN m Tensile strength (CD) (ASTMD 4595) = ≥12 kN m Tensile Elongation (ASTMD 4595) = ≥5% & ≤30% Grab Elongation (ASTMD 4632) = ≥5% & ≤30% Tensile strength (ASTMD 4632) = 1.5 KN UV resistance (ASTMD 4355) = 70% 500 hrs Note:- (Bags are to be supplied of 100 or part in a bundle, properly packed with name of Manufacturer and Batch is to be marked on each bag with “XXXXX” to be printed on each bag and mentioning properly the GSM and type of Geo bag polymer. Test Certificate from approved NABL accredited BTRA CSMRI and ISO Certified Laboratory should invariably be submitted against each batch of material). Total requirement is for 50,000 Bags 3. Supply of Continuous filament Nonwoven Geo-textile High quality 100% Polypropylene Fibres manufactured from high quality polypropylene staple fibres, The Geo-textile must be resistant to chemicals and biological organism normally founded insoils and must be stabilized against degradation due shorter exposureto U.V. Radiations. The material to confirm to EN-13253:2000, EN-13254:2000, EN- 13255:2000, ISO-10319, ISO-12236, ISO-12956, ISO-9864, ISO- 9863, ISO-10319, ASTM D 4632, ASTM D4633. 4.
