ABSTRACT
Textile is no more used only for interior or apparel application like carpets, curtains or shirting and suiting but also used in civil engineering for temporary as well as permanent structures. Current era we are more focused in construction, houses and building designs have more sunlight, greener, high performance, cost saving and sustainable structure. To fulfill that requirements textile play a fundamental role. Textile used in buildtech, geotextiles, architectural, green roofs and new development of 3d printer for houses. The reinforcement of construction parts for structural and civil engineering applications with textiles offers many opportunities including the manufacture of very thin materials, and the ability of manufacture structural parts with complex shapes. The basic materials and manufacturing techniques used for reinforcing textile are summarized. Textile fabric made from glass, aramide, or carbon fibers crosslink with resign to made composites have high modulus, high strength and high mechanical properties that enable textile materials to use in civil engineering applications. These materials have high strength and stiffness with respect to weight and provide great flexibility in design and use to engineer textile reinforce concrete (TRC) composite material with performance similar to steel reinforced concrete, giving light weight structures with high durability and high quality surface. Textiles have increased usage indoor and outdoor for surface and hidden applications. Textile traditional use in houses but textile is also used in acoustic and thermal insulation, protection of building against some wind, fire, water. Textile fibers are used with concrete to enrich its properties and lowering the cost and protection against UV and electromagnetic radiation.

KEY WORDS: Civil engineering, Technical textile, Buildtech, Geosynthetic, Reinforcement.

1. INTRODUCTION
Textile is very conventional and never ending field. Textile is one of important part of our daily life. Initially textile was used only for clothing and household purpose but this field has expanded a lot not only in applications but also in technical textiles. A technical textile is used in civil engineering, buildtech, geotextiles, architectural and green roofs. Textile contributes itself in minor as well as major things. Wovens, nonwovens and knitted yarn and fabrics are widely used. Textile fiber composite is also used for civil engineering.

Technical textile are usually applied in following 12 main areas:

1. Agrotech
2. Hometech
3. Oekotech
4. Buildtech
5. Indutech
6. Packtech
7. Clothtech
8. Mobiltech
9. Protech
10. Smarttech
11. Geotech
12. Medtech
13. Sportech

1.1 CIVIL ENGINEERING:
It is abroad field of engineering that deals with the planning, construction, and maintenance of fixed structures, or civilization and their processes. Most civil engineering today deals with power plants, bridges, roads, railways, water supply, irrigation, transportation, telecommunications, etc. It is broadest and oldest of engineering fields.

We are now going to deal with applications used in civil engineering which is mainly divided in two categories:

• BUILDTECH
• GEOTEXTILE

1.1.1 BUILDTECH:
Textile is also one of the oldest and well developed field all over the globe. Now a days, textile is widely used in civil engineering due to their special properties like high strength, modulus, elongation. Also prevent from UV rays, sound, radiation special textile material is used during construction of buildings.

1.1.1 GEOTEXTILE:
Geotextile is the combination of two words ‘geo’ comes from the Greek word meaning ‘earth’ and textile. Geotextile defined as “any permeable textile material used for filtration, drainage, separation, reinforcement and stabilization purpose as an integral part of civil engineering structures of earth, rock, other constructional materials”.

“Geosynthetic is a product which is used in contact with soil and other materials in geotechnical and civil engineering”. Textile is used for rail buildings, road, dam, canal, drainage, landfill, soil separation, etc.

2. RAW MATERIALS USED FOR CIVIL ENGINEERING:
Different types of material like natural as well as synthetic are used as raw material for technical textile.

Table 1. Raw material used in civil engineering

3. MARKET SCOPE FOR BUILDTECH (VALUE IN RUPEES CRORES):

TABLE 2. Market value for buildtech (value in rupees crores)

4. MANUFACTURING OF GEOTEXTILE FABRIC:
Textile made natural or synthetic permeable resources, used with base soil, rock and other geotechnical material. The geotextile are further prepared in three categories:

4.1 WOVEN FABRICS:
Woven geotextile are manufactured weaving technology as standard clothing textile. Geosynthetics are of woven type, which can be subdivided into categories based upon their method of manufacture. This type has characteristic appearance of two sets of parallel threads of yarn that is warp and weft. Geotextile it is compose of two sets of parallel yarns. Interlaced to form a planner structure which include multifilament woven, monofilament woven, slit film woven.

4.2 NONWOVEN FABRIC:
Nonwoven manufactured from either short staple fiber or continuous filament yarn. The fiber can be bonded by thermal, chemical, mechanical or mechanical techniques. Fibers are bonded together into a planar structure, which include following:

• Nonwoven mechanically needle punched
• Nonwoven heat set.
• Staple fiber and continuous filament fiber

4.3 KNITTED FABRIC:
Interlocking a series of loops of yarn together. All of knitted geo-synthetics are formed by using the knitting technique in conjunction with some method of geo-synthetic manufacturer. Knitted geotextile are subset to woven geotextile and are found as filters on pipes in two stage filter. multilayer geotextiles re formed by bonding together nonwoven or woven geotextile. They give high protection geotextile.

PET and PP are mostly used synthetic in civil engineering.

WHY PET IS MORE PREFERABLE THAN PP IN CIVIL APPLICATIONS?

5. SOME CERTIFICATIONS FOR THE TEXTILES THAT USED IN CONSTRUCTION:

• CE:-Marketing of textile, resilient and laminate floor coverings, wall coverings
• Oeko-tex standard 100: Absence of harmful substances
• Gut:-Eco-friendly carpet production
• IGI:-Quality mark for wall coverings

7. NEW/MODERN APPLICATION OF TEXTILE IN BUILDTECH:

7.1 NANO TEXTILE IN CIVIL ENGINEERING:
In buildtech and geotextiles, nanotechnology play a vital role in a different way. Nanotechnology improve existing textile properties & offered additional functional performance by increasing chemical, mechanical, biological & photochemical properties. In buildtech the nano fibers and nano tubes are used to made, lighter & stronger, concrete materials which run longer & more capable to resist strong shocks generated by earthquakes also provide thermal insulation, controlled light transmission. “An example is the seismic wallpaper composite concept, based on a reinforced textile composite system, combining different materials like multiaxial, warp knitted glass and polymer fibers, nano particle-enhanced coatings for the textile fabric, nano particle-enhanced mortar to bond the textile to the structure, and fiber-optic sensors. The seismic wallpaper is now past the prototype phase taking the first steps towards commercialization”.

7.1.1 Application of Nanotechnology in Building:

• Self-healing concrete
• Wrapping of existing columns
• Protection against earthquake
• Reinforcement of critical walls
• Explosive incidents and protection purpose
• Localized crack repair

7.2 Architectural Textile:
Majority of people spend one or more nights in tent & get advantage from protection offered by its fabric. Textiles are light weight, easy to handling, flexibility and they provide protection against wind, U.V radiations, snow and rain. such as self-cleaning, odor control, thermal insulation and lightness. Hence textile elements require a great engineering skills.

In past few years, the use of textile materials in architectural membranes resulted in the construction of as airports and sports stadiums, provide much lighter and functional properties. Sun and weather protection as well as light and temperature regulation are the main requirements for textiles applications in new sports stadium” Around 80% of newly built or refurbished stadiums worldwide have textile roofs and/or claddings”. Another textiles application in architecture is inflatable buildings. With respect to textile materials useful in architecture, the most used are fibers are polyamide, polyethylene, polyester, glass, and optical fiber. For architectural membranes, textile structures are impregnated with polymers such as P. V. C, silicone and PTFE.
