It defines shrinkage and explains that it occurs when fibers revert to their natural physical state after being stretched during processing like spinning and weaving. The factors that control shrinkage are discussed like fiber type, construction method, finishing processes and tension levels. The different types of shrinkage like relaxation, thermal, residual and progressive shrinkage are defined. Methods to reduce and control shrinkage are outlined like cylinder processing, chlorination, resin treatments, heat setting and sanforizing. The sanforizing process subjects fabrics to moisture and tension to pre-shrink them in a controlled manner. Testing methods to measure shrinkage are also summarized.
Brethable fabric
Waterproof breathable fabrics allow water vapor to pass through while preventing liquid water. There are three main types: densely woven fabrics using fine fibers, membranes made of thin polymer layers, and coated fabrics with microscopic pores or hydrophilic coatings. These fabrics are used in sportswear and outdoor clothing to transport moisture away from the skin through capillary action while maintaining breathability.
Water Repellency and flame reterdent
Water repellency and flame retardancy are important textile properties. Water repellent fabrics resist water penetration and allow water to roll off, while waterproof fabrics have fewer pores and are less permeable. Several tests evaluate water repellency, including the spray test where water is sprayed on samples rated based on wetting. The Bundesmann test subjects samples to high-pressure water for 10 minutes to measure penetration and absorption. Flame retardant finishes can save fabrics from fire using compounds of phosphorus, antimony, and boron. The vertical flame test exposes samples to an open flame to evaluate flame retardancy based on after flame and char length. Proper testing ensures textiles have sufficient water repell

It explains that the filter cake, not the bag itself, does most of the filtering. Guidelines are provided for filtration velocity, dust concentration, insulation needs, and other design factors. Filter bag selection criteria include the cleaning mechanism, dust properties, temperature, and allowed dust levels in cleaned gas.
Baghouse

Air dyeing mechanism
The document discusses various waterless dyeing mechanisms, including air dyeing, supercritical fluid (CO2) dyeing, plasma treatment dyeing, and foam dyeing. Air dyeing uses high pressure air flow to transport atomized dye onto fabrics without water. Supercritical CO2 dyeing dissolves and deposits dyes using compressed CO2 above its critical point. Plasma treatment increases fabric wettability before dyeing. Foam dyeing pads fabrics with dye-containing foam to reduce water usage. These techniques aim to reduce the textile industry's environmental impact by consuming less water and energy during dyeing.

The Evolution and Impact of OTT Platforms: A Deep Dive into the Future of Ent...
This presentation provides a thorough examination of Over-the-Top (OTT) platforms, focusing on their development and substantial influence on the entertainment industry, with a particular emphasis on the Indian market.We begin with an introduction to OTT platforms, defining them as streaming services that deliver content directly over the internet, bypassing traditional broadcast channels. These platforms offer a variety of content, including movies, TV shows, and original productions, allowing users to access content on-demand across multiple devices.The historical context covers the early days of streaming, starting with Netflix's inception in 1997 as a DVD rental service and its transition to streaming in 2007. The presentation also highlights India's television journey, from the launch of Doordarshan in 1959 to the introduction of Direct-to-Home (DTH) satellite television in 2000, which expanded viewing choices and set the stage for the rise of OTT platforms like Big Flix, Ditto TV, Sony LIV, Hotstar, and Netflix. The business models of OTT platforms are explored in detail. Subscription Video on Demand (SVOD) models, exemplified by Netflix and Amazon Prime Video, offer unlimited content access for a monthly fee. Transactional Video on Demand (TVOD) models, like iTunes and Sky Box Office, allow users to pay for individual pieces of content. Advertising-Based Video on Demand (AVOD) models, such as YouTube and Facebook Watch, provide free content supported by advertisements. Hybrid models combine elements of SVOD and AVOD, offering flexibility to cater to diverse audience preferences.
Content acquisition strategies are also discussed, highlighting the dual approach of purchasing broadcasting rights for existing films and TV shows and investing in original content production. This section underscores the importance of a robust content library in attracting and retaining subscribers.The presentation addresses the challenges faced by OTT platforms, including the unpredictability of content acquisition and audience preferences. It emphasizes the difficulty of balancing content investment with returns in a competitive market, the high costs associated with marketing, and the need for continuous innovation and adaptation to stay relevant.
The impact of OTT platforms on the Bollywood film industry is significant. The competition for viewers has led to a decrease in cinema ticket sales, affecting the revenue of Bollywood films that traditionally rely on theatrical releases. Additionally, OTT platforms now pay less for film rights due to the uncertain success of films in cinemas.
Looking ahead, the future of OTT in India appears promising. The market is expected to grow by 20% annually, reaching a value of ₹1200 billion by the end of the decade. The increasing availability of affordable smartphones and internet access will drive this growth, making OTT platforms a primary source of entertainment for many viewers.
