Online class(Google meet)prepared by: M.Rishana class: III B.Sc CDF Date:25/10/2021 INTRODUCTION Geotextiles are permeable fabrics which, when used in association with soil, have the ability to separate, filter, reinforce, protect, or drain. Typically made from polypropylene or polyester, geotextile fabrics come in three basic forms: woven (resembling mail bag sacking), needle punched (resembling felt), or heat bonded (resembling ironed felt).
Online class(Google meet)prepared by: M.Rishana class: III B.Sc CDF Date:25/10/2021 Geotextile composites have been introduced and products such as geogrids and meshes have been developed. Geotextiles are able to withstand many things, are durable, and are able to soften a fall if someone falls down. Overall, these materials are referred to as geosynthetics and each configuration -geonets, geosynthetic clay liners, geogrids, geotextile tubes, and others -can yield benefits in geotechnical and environmental engineering design.

Online class(Google meet)prepared by: M.Rishana class: III B.Sc CDF Date:25/10/2021 Geotextiles and related products have many applications and currently support many civil engineering applications including roads, airfields, railroads, embankments, retaining structures, reservoirs, canals, dams, bank protection, coastal engineering and construction site silt fences or geotube. Usually geotextiles are placed at the tension surface to strengthen the soil.
Online class(Google meet)prepared by: M.Rishana class: III B.Sc CDF Date:25/10/2021 Geotextiles are also used for sand dune armoring to protect upland coastal property from storm surge, wave action and flooding. A large sand-filled container (SFC) within the dune system prevents storm erosion from proceeding beyond the SFC. Using a sloped unit rather than a single tube eliminates damaging scour
Online class(Google meet)prepared by: M.Rishana class: III B.Sc CDF Date:25/10/2021 Erosion control manuals comment on the effectiveness of sloped, stepped shapes in mitigating shoreline erosion damage from storms. Geotextile sand-filled units provide a "soft" armoring solution for upland property protection. Geotextiles are used as matting to stabilize flow in stream channels and swales
Online class(Google meet)prepared by: M.Rishana class: III B.Sc CDF Date:25/10/2021 Geotextiles can improve soil strength at a lower cost than conventional soil nailing. In addition, geotextiles allow planting on steep slopes, further securing the slope. Geotextiles have been used to protect the fossil hominid footprints of Laetoli in Tanzania from erosion, rain, and tree roots. In building demolition, geotextile fabrics in combination with steel wire fencing can contain explosive debris.

Separation Geotextiles will prevent two soil layers of different particle sizes from mixing with each other, as is illustrated the image below. . 2. Drainage Geotextiles will efficiently collect superfluous water from structures, such as rainwater or surplus water, from the soil and discharge it.
Online class(Google meet)prepared by: M.Rishana class: III B.Sc CDF Date:25/10/2021 . 3. Filtration Geotextiles are an ideal interface for reverse filtration in the soil adjacent to the geotextile. In all soils water allows fine particles to be moved. Part of these particles will be halted at the filter interface; some will be halted within the filter itself while the rest will pass into the drain. The complex needle-punched structure of the geotextile enables the retention of fine particles without reducing the permeability of the drain.

Thanks to their high soil fabric friction coefficient and high tensile strength, they are an ideal reinforcement solution. 5. Protection Geotextiles are an ideal protection from erosion of earth embankments by wave action, currents or repeated drawdown. A layer of geotextiles can be placed so as to prevent leaching of fine material. They can be used for rock beaching or as mattress structures. They can even easily be placed under water

Most Automobile filters manufacture from textiles, such as air filters and oil filters. The most essential part of these automobile filters is to filter the fluid before enters the engine. It separates dirt and dust particle enters into the automobile engine. The automobile industry is constantly evolving, with the latest models being more efficient, faster, and safer than ever before. The textile industry has also been revolutionized by new technologies that offer various textiles for automobiles. Innovative mobiltech materials have now been used in seats, headrests, sun visors, and floor mats to provide comfort and protective equipment while promoting safety for drivers. The mobiltech textiles industry focuses on innovative materials that can withstand extreme temperatures, moisture, and wear while providing a luxurious feeling to the driver. It is made of natural fibers such as cotton or wool, which resist shrinkage and fading with constant use. Automotive textile manufacturing industries also offer synthetic fabrics for those who want minimal upkeep but prefer the look of natural fibers.
Online class(Google meet)prepared by: M.Rishana class: III B.Sc CDF Date:25/10/2021 The use of automotive textiles in the industry is not new, but the quality and variety have grown immensely with time as technology keeps advancing. Automobile manufacturers now offer a selection from which to choose that can suit any driver s needs, whether they want durable fabrics for extended trips or fine, soft materials for short errands around town. Mobiltech textiles are improving the safety of drivers. The latest models come with advanced features such as built-in airbags, anti-lock brakes, and seat belts to keep passengers secure in a crash or sudden stop. Automobile textile manufacturers have developed their technologies for flame retardant fabrics, provide protection from UV rays, and offer sound insulation.
