What Is Medical Textile? || Process Flow Chat Of Medical Textile Technology

Medical textile is the most advanced technology in textile sector. It is the important technical textile. Medical textile is generally used for medical purposes in first aid purpose or clinical and surgery division. Medical textile products includes surgical drapes, surgical gowns, pads, masks, dressings, filtration materials, tissue scaffolds for rebuilding internal organs and many more. This type of medical textile is used for protective and health care purpose.

Process Flow Chat of Medical Textile Technology: Medical textile products are prepared in a line of process. Higher textile technology is used for manufacturing medical textile products. Special types of machineries are used for producing medical textile products. Followings are the most common procedure of manufacturing medical textile products:

Polymer

Spinning

Yarn modification

Textile production

Tailoring

Testing

Textile implements

Above flow chat is the simple line up for medical textile technology.

Geo Textiles || Functions Of Technical Geo Textiles

Geo textile is the most important technical textile. It is used to protect the environment from the different bad affects of the world. Geo textiles are used in road infrastructure, railways, waste landfills, dams, irrigation, hydraulic structures etc.

Functions of Technical Geo Textiles: Functions of geo textiles are given below:

Reinforcement: Reinforcement is the most important function of geo textiles. Composite technical geo textile materials allow water flow within the plane surface of the water, rather than across it. This behaves like a retaining wall behind water. By the EN ISO standards, the reinforcement function is defined as “The use of the stress-strain behavior of a geo textile or a geo textile-related product to improve the mechanical properties of soil or other construction materials”.

Separation: Basically geo textile is used for separation and it is widely used in railway and road work construction. Geo textile preserves the integrity and extends the life of the road surface layer. Geo textile materials placed between different layers in the construction, it prevents migration and mingling of materials. It also allows free movement of water. By the EN ISO standards, the separation function is defined as “The preventing from intermixing of adjacent dissimilar soils and/or fill materials by the use of a geo textile”.

Filtration: By the EN ISO standards, the filtration function is defined as “The restraining of soil or other particles subjected to hydrodynamic forces while allowing the passage of fluids into or across a geo textile”. Geo textile material also used to filter. It allows water movement while preventing movement of soil particles.

Surface Erosion Control: Geo textile also used to control the surface erosion. When water flows over the surface it causes erosion, by using geo textile it is possible to control the erosion.

Protection: By the EN ISO standards, the protection function is defined as “The prevention or limiting of local damage to a given element or material by the use of a geo textile”. Waste disposal system and tunnel constructions are also depends on geo textiles. It is used as geo-membrane. It ensures the integrity of sealing materials when fill material and load are applied.

Drainage: By the EN ISO standards, the drainage function is defined as “The collecting and transporting of precipitation, ground water and/or other fluids in the plane of the geo textile”. For drainage in earth and construction works, geo textiles are widely used. In drainage system, geo textiles are used to flow water over the plane surface of the soil with minimum pressure of the water over soil. This function is different from the filtration.

Stress Relieving: Geo textile also used as a stress relieving materials.

So, there are lots of functions of geo textiles.

Supply Chain of Automotive Technical Textiles

In automotive technical textiles industries; there have a supply chain by which automotive technical textile forward from raw material to the delar. It is important to know the flow chart of supply chain. It is a process by which we get automobiles. So, we need to know the process sequence. Here I have written about the supply chain of automotive technical textiles.

Supply Chain of Automotive Technical Textiles: Process sequence of automotive technical textile product manufacturing is given below.

Fiber

Yarn

Fabric

Foam

Laminate

Cut and Sew

Assemble/Mold

Component

Interior

Vehicle

Delar

Here, fiber is turn into yarn by spinning process, and then yarn is used to make fabric by weaving/no weaving or knitting process. It is the primary stage of manufacturing.

In the secondary stage, fabric is laminated by the process of foaming. After that laminated fabric is cut into desired size and sewing is done. Then assembling or molding is done.

In the final stage; component is assembled for using in vehicle manufacturing. At last, complete vehicle goes to the Delar.

So, it is a sequence of automobile textile product manufacturing.
