Write about the changes in technology of textile industry .
One of the biggest challenges facing the textile industry is how to deal with the massive amount of waste it produces every year. Textile recycling is one way of dealing with this problem. Old clothes, blankets, and other textiles can be recycled to create new shoes, reusable bags, and more. It is a far better solution than simply throwing old fabrics away in landfills.
As we continue to create more sustainable textiles, knowing what materials are in our textiles is becoming increasingly important. It means knowing exactly how much of each material is used in the production process (including any chemicals or additives), how many garments can be created from one roll of fabric, and so on. To help with this task, various processes have been developed to measure and test textiles. For example, the “Knitted Knock-Knock” test uses a particular machine to knock on textiles, allowing it to determine precisely how much air is trapped in the material. There are also various other tests related to fabric strength and durability that have been developed over time.
One of the biggest challenges facing the textile industry today is trying to produce more sustainable fabrics. It means using less energy during production and ensuring that any materials used can be easily recycled at the end of their lives. Different technologies have been developed over time that can help achieve this goal. One example is “closed-loop” dyeing, which significantly recycles water and chemicals to reduce their environmental impact. Another is nanotechnology, which uses tiny particles to create new materials for entirely different purposes than those initially designed. These are just two examples of the many ways we’re finding to create more sustainable textiles.
One of the most noticeable changes in textile decoration has been the influx of colorful and complex computer-generated patterns and prints over recent years. It has been made possible through technologies such as those used by one company called Fabricant, which produces special sprays that can print patterns onto fabrics. Another example is a technology developed by researchers at MIT, which allows us to print designs onto fabric using materials including silver nanoparticles, proteins, and living cells. It opens up a whole world of possibilities for textile decoration, allowing the production of everything from funny prints featuring cartoon characters to fabrics with medical imaging data printed directly onto them!
Industries are moving - some faster than others - but ultimately they will all have to. Even the most traditional, such as the textile industry, in which it has been common for people who work there to do so for decades, in which it is a tradition that children's children continue in it. So how is change promoted in this industry?
During the Innovation Forum 2019, an event held in Bogotá last June, former Deputy Minister of Digital Economy Daniel Quintero Calle shared his experience during a visit to the Arturo Tejada fashion design and marketing school. There, he asked the students what they were going to work on, to which they replied that surely in recognized companies such as Leonisa or any other in the textile industry. «I asked them if they had already considered working in the video game industry, because it turns out that now those companies hire designers so they can make their characters' outfits ».
This is one of the many examples that can be listed. It is likely that people who are studying a career today, whatever it may be, are working on something they had not imagined. 
For this reason, and following the objectives of the Paris Agreement, leading companies committed to reducing their greenhouse gas emissions by 30% by 2030, as reported by CNN. They also agreed to prioritize low-carbon transport providers and favor climate-friendly materials. It is a global commitment, many solutions are needed here from the ideation, the manufacturing, distribution, sale and disposal process. Here the circular economy is also key.
Sustainable fashion It is a new trend that is gaining strength, reusing garments. Big brands already implement programs for users to deliver their travel clothing in exchange for bonuses, in some cases, to then make new pieces of clothing. 
Immersive experiences
If there is one thing that defines this era, it is personalization. Customers want specific things, molded to their liking and that they can experience before making the purchase; clothing is clearly no exception. In fact it is one of the fields that can offer the most solutions.
Immersive technologies such as Virtual and Augmented Reality they allow users to see and 'test' how they would look with a certain garment, if it is better in blue, red, green, longer, shorter or with prints. In other cases, the potential of voice assistants such as Alexa is exploited, who become fashion consultants.
Recognized brands already use Virtual Reality to sell in their stores. The user only needs to focus the phone to different points in the store and they will see a model with different brand clothes.
These are not the only innovations. Without a doubt, with the passage of time and the new demands of the world, this and other industries will have to keep moving, constantly transforming. The challenges of culture and training are transversal, it is necessary to understand the current environment and train people with new skills.
In a study published in 2016 by the 'European Technology Platform' entitled 'Towards a Fourth Industrial Revolution of textiles and clothing. A strategic research and innovation agenda for the European textile and clothing industry ' se outlined 3 trends that would be positioned in 2025: digitization and virtualization, collaboration and pay-per-use, and sustainability and circularity. Today we can see that there are several additional trends to add, and it has only been 3 years. 

The technology for developing it from IIT Delhi to develop a digital image processing based pilling tester for objective evaluation of pilling instead of subjective and visual comparison. After the successful development it is expected that international standards like BS, ASTM, DIN and IS will incorporate the development as new standard for evaluation of pilling.

The main function of Pilling Tester is to test the pilling (hair ball) characteristic of fabric and knit fabric cloths. Simulating the condition of when weaving materials are worn, it will have the appearance of lint. Rolling the specimen around a rubber tube and turning in a winding box for a period of time, it is then compared to a standard picture to determine its grade. Test results are usually determined after comparing with standard pictures, the average of four tests per specimen.

But this development involves conversion of pilled fabric sample to digital image and stored in a memory by the image acquisition element. This image will be processed to obtain the various parameters like no. of pills, total pilled area, mean pill area and no. of pills per unit area.

Under the heading Industry 4.0, many physical and digital technologies are converging through analytics, robotics, artificial intelligence, digitization, and the internet of things, such as Textile Industry 4.0.
These technologies are creating digital companies that can communicate, collect and analyze data on machines enabling faster, more flexible, and more efficient processes, which will help produce high-quality goods at reduced costs.
This revolution will end up strategically contributing to increased productivity, considerably improving the economy of all segments of the industry, but especially fashion and food and service goods, resulting in real and progressive growth and a total change in the competitiveness of organizations worldwide.
Strictly speaking, with regard to the Textile and Apparel and Textile Industry 4.0. Due to the intensive use of labor, lack of technology, and rising costs, the competitiveness of the textile industry is weakening in many countries.
The result of these constraints, ranging from the level of productivity and efficiency to quality, is always affected in most cases. We also have a new trend is to have product customization with more variations, requiring an adjustment to market needs in the shortest time possible.
In addition, all product lifecycles are being considerably shortened with intense changes. Perhaps Industry 4.0 can help the textile and apparel industry solve these problems with the possibility of flexible manufacturing, industrial process redesign, and technological advances.
Most machines supplied by textile machinery manufacturers have built-in intelligent factory platforms so that they can collect, measure and analyze data through sensors, data loggers, etc.
And this information is used in the user interface to carry out actions or decisions. All processes related to manufacturing and logistics can become more flexible and agile in the textile value chain in Têxtil 4.0. This will help to respond quickly and effectively to market needs.
