Textile: Crisis:

November 17, 2007 · Filed under Textile · Tagged , , ,

 

Human capital is one of the most important and influential asset in this century. This capital should be recognized by the industries of course they are doing it. In textile industry intelligent human capital is important one as this industry mainly driven by the foreign imported machineries, technological backup, even testing apparatuses. What is the reason behind this status? Is this is the failure of the institutes or industries?.

Setting up an research and development team and product diversification is important one as our economy is getting strengthen. In this blog I would like to discuss various issues right from the zero point.  The critical need for the industry is to entitle managerial  executives with  knowledge and skills to analysis the global economic scenario and current research areas to promote the products.

 

With the influence of America whole world is getting as the copy of the American economic policies. Due to the change in economic conditions many peoples are now enjoying the taste of Mc Donald’s dinner. But many Indians are far away from the taste of Burger and Pizza, their search is for one complete square meals for a day. People of India are far away  from the economic reforms and the latest technologies.

The industry has to review many of its old plans and operating principles. They have to invest huge capital for the research and development – which we haven’t done yet. Our system runs only the quality control department not the R&D. secondly the industry institute interaction – which our Indian textile industries are limiting up to the level of providing samples for the research work. This is not the way to promote the research, however many industries may not able to carry out the research with their facilities, they have to tie up with the institute to promote themselves. Even highly developed industries are not considering over the research, they are doing research on the market and profit not over the product / materials. We have to take a view over the pre and post cold war era, the period which provided many of the technologies to the world; majority of the technologies were developed by the joint venture of institute and industries. See in a practical aspect, in a single industry there may be few minds to work for the problem but in institute you can find plenty of young minds who can percept beyond the spectrum of the industry. (of course to some extend.) Thirdly the ways to meet the crisis. As the dollar value decreased those who are dealing with the dollar they might be facing huge profit losses  (not true exactly, as they wont share the profit with the employees but if loss occurs, employees will be losing their monetary benefits – as we are like caterpillar; yes caterpillar never enjoys the silk but it keep on spinning.) they have to think innovative to approach this crisis. Apart from the estimating the dollar for the least value, industry has to view with the broader spectrum, they have to look expenditures for energy, water, opportunities to invest in foreign. Industries can try the natural energy sources, recycling of water, effective utilization of water resources or can promote the awareness about water resource up keeping. In the mean time industry can thing about the foreign opportunity to invest / start their industry there. Finally the government has to think about keeping the stable currency as well as balanced budget, of course we are successfully doing this, but apart from this, country has to monitor over the balance of international trade with in the various industries.

 

Apart from all, industry has to secure / capture young brilliant minds with their industry, which they never imagine to do and even they wont do. Why iam saying this means many of our young professionals are changing their field after their graduation. The main reason for this is the low wages. Yes that’s true, who  will work with dedication for 10$ per day? Is it right salary for the intelligent kids who are having big dreams to achieve?, is it possible for them to eat two diets while their counterparts are enjoying Pizza and Burger? No not at all. I would like to disclose about one of my friend, who developed a unique software for the fabric design which possess many good features which are not available with the common available package, but when he approached for the job he came to know that he has to work for 7$ per day. He just collapsed and left this textile field and joined in softwares and earning  25$ per day. This is the scenario.  

 

what is the future plan for the industry and professional if this situation gets worst?. However each industry has its own consultant or adviser but what happen for the small scale industries?. What kind of initiative should have done by the Indian ministries? Industry really need real research activity;

Which they haven’t carried out so far. This research should focus in  a multi direction with the dream to bring back the pride which many of our textile professionals lost in the past years. Let us bring the world attention by doing some thing different and make our professionals to feel proud like their counterparts.

முடிகொண்டான்

November 17, 2007 · Filed under My town: My Story, Uncategorized · Tagged , ,

முடிகொண்டான் இயற்கையில் அழகான ஆர்ப்பாட்டம் இல்லாத ஆனால் ஆர்ப்பாட்டம் நிறைந்த மனிதர்களை பெற்ற ஒரு கிராமம். 1950 களின் பிற்பகுதிகளில் பிராமண பண்ணையார்களின் ஆதிக்கம் நிறைந்து பின் 1990 முதல் பிராமண பண்ணையார்களின் நிலங்களை விலைக்கு பெற்ற பிற பிராமணர் அல்லாத பண்ணையார்களின் ஆதிக்கம் தொடர்கிறது. இதனால் சாதாரணமான மக்களின் நிலைப்பாடுகளில் எந்த ஒரு பெரிய மாற்றமும் எற்படவில்லை. இந்தியாவின் பிற கிராமங்களை போன்றே சுயநல அரசியல் வாதிகளும், வாங்கும் சம்பளத்திற்கு 40% (விழுக்காடு)மட்டுமே வேலை பார்க்கும் பள்ளிக்கூட ஆசிரியர்களும் (இவர்களின் இந்த 40%இல் இந்த உலகுக்கு கிடைத்த ஒரு சிந்தனையாளன் (இப்படித்தான்  ஊ)  தான் நீங்கள் படிக்கும் இந்த கிறுக்களுக்கு சொந்தக்காரன்), படித்த பின் எதிர்காலம் பற்றிய சிந்தனை இல்லாத அக்மார்க் கிராமத்தான்களும் நிரம்பி (!?) வழியும் கிராமம் தான் எனது ஊர்.

பள்ளிக்கூட வாழ்க்கை என்பது இந்த கிராமத்து குழந்தைகளுக்கு – கடலில் வீசப்பட்ட மரத்துண்டு போல. ஆம் மரத்துண்டு வெற்றிகரமாக கரை கண்டால், இங்கு கடலோ அல்லது மரத்துண்டோ வெற்றியை யாருக்கும் தன் வெற்றியை ஸமர்ப்பிக்க முடிவதில்லை ஏன் என்றால் இது இயற்கையாக நடக்கும் செயலாகும்.

இப்படிப்பட்ட பெருமை (!!??) வாய்ந்த ஊரில் நான் பார்த்த/ அனுபவித்த நிகழ்ட்சிகளை இங்கு தொகுத்தளிக்க உள்ளேன். .

தீபாவளி: என்ன கொடுமை இது!!??

November 17, 2007 · Filed under General (பொது) · Tagged , ,

தீபாவளி என்றாலே ஒரு பரபரப்பு தொற்றிக்கொள்ளுவது வழக்கம். ஆனால் இந்த முறை சிறு வயதில் அடைந்த உற்சாகம் இந்த முறை எழவில்லை. முன்பெல்லாம் தீபாவளிக்கு பல நாள் முன்பே பட்டாசு வாங்கப்பெற்று அதை நான்கு பங்குகளாக பிரித்து அதை கண்ணும் கருத்துமாக வெயிலில் காய வைத்து பின் தீபாவளி வரும் வரையில் எதிரிகளிடம் இருந்து அதாவது எனது சகோதரிகளிடமிரிந்து பாதுகாத்து, தீபாவளி அன்று யார் முதலில் சரம் வைப்பது என்ற போட்டியில் தொடங்கி, அடுத்த வீட்டு அண்ணன்கள் வைக்கும் வெடிகளுக்கு பயந்து இறுதியில் ஒரு வழியாக பட்டாசுகளை காலி செய்து விட்டு, அடுத்த கட்டமாக ஆசி பெற்று வசூல் செய்ய என்று தீபாவளி அன்று எங்களது plan அமையும்.

ஆனால் இந்த முறை மேற் சொன்ன எந்த ஆர்ப்பாட்டமும் இல்லாமல் , காலை சன் டீவியின் மங்கல இசையுடன் தொடங்கி இறுதியில் எல்லா சேனல்கலையும் அலசி அனைத்தையும் பார்த்து இறுதியில் மூளை குழம்பி மிகவும் கஷ்டப்பட்டு தூங்க சென்றேன்.

 

மொத்தத்தில் பண்டிகைகளுக்கும் சினிமா கலைஞர்களுக்கும் என்ன தொடர்பு என்று எனக்கு புரியவில்லை. இப்படியே சென்றால் வார விடுமுறைகளையும் விளம்பரங்களுக்கும் சினிமா கலைஞர்களுக்கும் தாரை வார்த்து, விளம்பரங்களுக்கிடையே சிறிது நேரம் நிகழ்ச்சி ஒளிபரப்பும் நிலை வந்தாலும் வரலாம்.

Technical Textiles: Thermal Garments

November 17, 2007 · Filed under Textile · Tagged ,

Thermal Garments?

Part I

Thermal garments are garments to withstand the climatic condition of below 30°c. These garments provide warmth to our body and make us to feel comfort even in the sub zero temperature conditions. Apart from the normal clothing performance these garments should perform with required functional properties to meet with the climatic conditions. These garments are mainly divided into three different structures and apart from these structures additional gears are also considered along with the garments. Three different structures are inner structure, mid layered structure, protective layers. The extra gears are like helmet, gloves, shoes, socks etc.

 

Cold is a hazard to human health. Cold environments may affect human physiological as well as human psychology. The main aim of the thermal garments should be prevention of cooling and maintenance the heat balance at acceptable temperature level. The aim of thermal garments is to give barrier effect. The clothing should shield the body from outside condition1. Ergonomics and psychological consideration plays important role in determining the performance of thermal garments.

The comfort factor is important for all garments, while considering thermal garments comfort consists of various factors like weight of the garment, breathability, thermal insulation, permeable to moisture vapor, wind resistance etc8.

 

The acceptance of uncomfortable clothing by the users was sometimes very low and the purpose of that clothing may not be fulfilled. The aim of the functional clothing is to give protection from rain, snow or wind. The construction of the textile fabrics must fulfill the requirements, like the fabric should be wind proof and water repellent, water vapor transmission should be possible from the skin to outside of the clothing and winter clothing should be heat insulated2. Along with all, thermal comfort is important, which is defined as “Condition of mind towards the environment which express the satisfaction of the garment”. Thermal comfort comprises of important factors like, perception of warmth, humid, transportation of vapor, etc.

 

To study about the thermal resistance and evaporation one should know about the heat and mass transfer mechanism. Especially heat transfer mechanism like conduction, convection and radiation and its significance.

Heat transfer is energy in transit due to a temperature difference. Heat exchange between the body and the environment takes place at the skin surface by three ways namely, conduction, convection and radiation. Existence of a temperature difference between or in a medium leads to heat transfer. Heat and mass transfer plays important role while evaporation and body metabolism.

 

Apart from convection, conduction and radiation, heat loss may occur due to evaporation and respiration5. In the generated heat approximately 10% of human heat loss due to breathing, the majority is drawn off through skin. This loss of heat occurs in two ways, a dry heat transfer and moist heat flow. Dry heat transfer which is of radiation and heat conduction. Moist heat flow due to the evaporation of perspiration, we can say it as moisture transfer. Heat exchange from the skin to the environment is mainly influenced by the air temperature, humidity, wind speed, solar, sky, and ground radiation, and clothing.
