Introduction

Silk fibre is known for its strength, fineness, lustre and elasticity. The technology of production of spun silk yarn from waste silk involves a long sequence of machines. The operations involved in the process are degumming, opening, filling, combing, carding, drawing, roving and spinning. Some research workers have attempted to spin silk on the woollen and waste spinning systems. Spun silk yarns are used for manufacturing various dress materials and household items that have good aesthetic value. Cotton fabrics are also used for apparels and home textiles due to their comfort characteristics. Hence, blending of silk with cotton and manufacturing of blended yarns and fabrics will have both aesthetic value as well as comfort characteristics.

There has been a great demand for silk blended fabrics in recent years, due to increased price of raw silk.

Therefore, a study has been carried out at SITRA with the following objectives:

1.      Spinning of silk/cotton blended yarns in short staple spinning systems

2.      Evaluation of quality attributes of silk/cotton blended yarns

3.      Assessment of handle and comfort properties of silk/cotton fabrics

Abstract

Manufacture of yarn from Polyester- cotton core yarn is one of the most important developments in textile Industry. Use of core yarns is mainly aimed to improve the strength, comfort, durability, aesthetic and other functional properties of the final yarn. The article reports the results of investigation on core spun yarns made from polyester filament as core and cotton as sheath material.

Polyester filaments with different proportions were chosen for the core component and cotton at sheath total six different core yarns were made and results were compared with 100% cotton Ring Spun yarn.

It is observed that core yarns are having improved physical properties over that of 100% cotton ring spun yarn.

Introduction

Core yarn structure consists of two components, one of which forms the center axis or core of the yarn and other is the covering. Continuous multifilament yarn generally used as a core while cotton staple fibers are used for covering the filaments or used as sheath material.

Core spun yarn shows some improved characteristics over 100% spun staple yarn on 100% filament yarns. To improve the strength and comfort core spun yarn is preferred over blended staple spun yarn. There is a phenomenal improvement of durability & aesthetic property are observed by using core spun yarn. As the cotton is wrapped over polyester filaments improvements are on yarn properties like moisture absorption, heat resistance, air permeability, depth of shed in dyeing. The tensile strength of yarn increases because of presence of Polyester Filament at core, which is the main load carrier.

Introduction

Soy Protein Fiber (SPF) is the only protein fiber made from soybean cake. Their physical properties are same as that of synthetic fiber. It gives tremendous change in properties like smoothness/luster/comfort/absorbency/strength/shrinkage when mix with other fibers. For example; when soybean fibers mix with cashmere, it gives smooth quality with an enhancement of easy care properties. As a wool/soy protein fiber, it reduces shrinkage and increases ease of care. As a silk blend, it improves the properties of silk with the prevention of the fabric from sticking to the skin when wet.

Inspite of this, SPF is the only renewable botanic protein fiber. Its 16 amino acids are healthy and nutritional to people's skin. This fiber basically comes from soybean; plant massive in sourcing and rich in nutrition. It is a kind of an active fiber shows the superiorities of many natural fibers and synthesized one.

Processability/Pretreatment: SPF has different physical & chemical construction from natural protein fiber. During the production process we should select fit equipment and proper settings:

a)   Desizing: As we know, all textile materials (woven fabric/knitting) require desizing which can further be processed by enzymatic desizing, alkali or oxidative desizing. Mercerization is usually not recommended as SPF is unable to bear the strong caustic soda.

b)   Scouring & Bleaching: As we know, the purpose of using scouring & bleaching is to remove oil, lubricants & pigments. We may use hydrogen peroxide bleaching, reduction bleaching depending upon color. The natural color of SPF is curcuma which is difficult to remove. Hence use of bleaching is recommended for these fibers. In case of very light colors, it is preferable to use whitening agents.

Synthesis: SRF is an advanced textile fiber made from Soybean cake after oiling followed by new bioengineering Technique.

Firstly, protein is distilled from soybean cake & refined.Secondly, Use auxiliary agent & biological enzyme which make changes in the space structure of spherical protein. After that, Protein spinning liquid is confected by adding high polymersThirdly, once the liquid is cook, the 0.9-3 dtex fiber is produced by wet spinning which is further stabilized by acetalizing & then finally cut into short staples after curing and thermoforming.Features: Fabrics from SPF have the following features:

Luster: SPF have the luster of silk with excellent drapeComfort: It is soft, smooth & light weightAbsorbency: They have same moisture absorption as cotton & better moisture transmission than cotton.Easy Dyeing: The original state of the product has good dyeing penetration & colorfastness properties.Strength: They have higher breaking strength than wool, cotton & silk but less than that of polyesterShrinkage: These fibers don't shrink under infaluence of boiling waterEasy Care: These fibers are anti-crease, easy wash & fast drying

Shengma fiber is a new and exciting regenerated cellulose fiber from the Shengma plant. The western world knows this as bugbane rhizome. Shengma literally means ascending hemp, so called for the similarity of the leaves to those of the hemp plant. It is a common and fast growing plant throughout China that easily grows to about 3 ft tall.

If the property of Shengma fibre and Viscose are compared, then under normal temperature and dry condition, breaking tenacity of Shengma is less than that of viscose, while breaking elongation rate of Shengma is larger than that of viscose. In wet condition the change of Shengma fiber mechanical property is less than that of viscose. Crimp elasticity of Shengma fiber is worse than that of viscose. [1]

The Shengma fiber overcomes the defects of natural bast fiber such as [2]:

Poor close skin property;Easy to crumple;High dry and wet strength;Good moisture absorption permeability;Bacteriostatic and mildew proof;The Shengma fabric has the properties of:

Soapy handle;Good draping;Brilliant luster;Plump surface etc.Shengma is one kind of ideal textile fiber which gathers gorgeous, hygienic, comfortable and ecological characteristic as one unity. This textile fiber has good spinnability, the conventional equipment can meet the spinning requirement, and simultaneously it also can blend with other natural bast fiber to produce light and thin fabric, in order to enhance the grade of bast fiber fabric. Fabric of Shengma fibre feels smooth and soft, and has brilliant colour, of fabric is full and rich organization, good moisture absorption [1].

Conclusion [2]

Under normal temperature and dry condition, the breaking tenacity of Shengma is less than that of viscose, while the breaking elongation rate of Shengma is larger than that of viscose. The tenacity of Shengma fiber in wet condition is less than that in dry condition. The decline degree of tenacity of Shengma fiber in wet condition is less than that of viscose fiber. The breaking elongation ratio of Shengma fiber in wet condition is 1.29 times higher than that in dry condition.The tenacities of Shengma fiber in both knot and hook joint modalities are less than that in straight modality. The dynamic and static friction coefficients of Shengma fiber are smaller than those of viscose fiber, the dynamic friction coefficient between Shengma fibers is bigger than that between the metal roller and Shengma fibers, and smaller than that between rubber roll and Shengma fibers.The crimp ratio of Shengma fiber is smaller than that of viscose fiber, the crimp recovery ratio and the crimp elasticity ratio are also smaller than those of viscose fiber, and this shows that the crimp durability and the crimp recovery ability of Shengma fiber are poorer than those of viscose fiber.References:

When NASA released the results of a 10-month study on Toyota vehicles on Feb. 8 concluding that the automaker’s cars did not have an electronics problem that caused unintended acceleration, one of Bloomberg BusinessWeek’s columnists said the media owed the company an apology. There is no ghost in the machine and the intense media coverage caused a frenzy, Bloomberg BusinessWeek columnist Ed Wallace wrote. I know Ed personally and have tremendous respect for him. But I must part ways on this issue.

Toyota may not have had electronic throttle issues. But certainly the company had plenty of other problems. Just today, Toyota announced its biggest recall in a year. The Japanese auto giant recalled 2.17 million vehicles because of carpet and floor mat flaws that could jam gas pedals. Toyota has recalled more than 12 million vehicles globally since November 2009, many of them related to unintended acceleration claims. Of those actions, 5.3 million vehicles were recalled to fix floor mat problems. Some of the cars were recalled because of a sticking accelerator pedal. It may not have been electronics, but there were problems.

Toyota has had other investigations and recalls not related to unintended acceleration. Last week, the National Highway Traffic and Safety Administration opened an investigation into the 2006 Highlander hybrid amid claims that the SUV stalls frequently. In January, Toyota voluntarily recalled 1.7 million vehicles for potential defects in fuel pipes and pumps, Bloomberg reported. On Jan. 10, Toyota CEO Akio Toyoda told reporters that the recalls have inflicted “big damage” on the company, but he maintained that its cars are safe, Bloomberg reported at the time.

Back to the apology. While it’s clear that there is no mystery magnetic glitch in Toyota’s cars and that they are as safe as anyone else’s vehicles, forget the apology. First of all, investigations are news. So long as the media reports the conclusion, it’s in the public’s interest to know what’s happening. Second, Toyota’s lost its once-astute focus on quality. Rapid expansion of its model lines and sprawling archipelago of factories has made it difficult to mind every detail, which was a principal tenet of the company.

Consumer Reports has found a decline in the quality of interior finishes in Toyotas for the past three or four years, David Champion, the magazine’s director of automotive testing, told Bloomberg for a Jan. 12 story. The company whose customers once relied on Toyota for bullet-proof quality and reliability suddenly suffered a rash of problems. In fairness to my old pal Ed, some media reports accepted the unintended acceleration claims as gospel. But that alone does not exonerate Toyota. Sorry Ed, but it’s the customers - not Toyota - who deserve the apology. Toyota’s executives have apologized, and justifiably so.

There’s a subtle rivalry brewing in the luxury car business. Audi and Cadillac are both hamming it up with television advertising to make the case that they’re the hip antidote to stodgy traditional luxury (read: Mercedes). In recent ads, both of them have new commercials loaded with imagery painting luxury as cold and stuffy as they take a fun stab at old money.

One of Cadillac’s newest ads depicts an older couple having an anniversary dinner at their long dining room table. Actor Laurence Fishburne intones, “blue-blooded, cold.” Cut to racy imagery: a motorcycle roaring down the highway, a young guy eyeballing a beautiful woman in a glass elevator. The ad eventually goes to a Cadillac CTS and Fishburne asks, “What happened to luxury? Where did the personality go?” The point, of course, is that Cadillac brings something new and edgy to the luxury market. The theme is “red-blooded luxury.”

Audi takes it a step further. On one of the German brand’s newest ads is an obvious play off the classic Margaret Wise Brown kids’ book “Goodnight Moon,” with a vaguely creepy animated fox fur and other classic luxury items such as a well-coiffed French poodle and gold cuff links. “Goodnight outdated. Goodnight stuffy,” the ad says. “Good night old luxury and all of your wares.” Then we see a Mercedes sedan. Its lights go out. The ad concludes with a beauty shot of an Audi A8 sedan and we hear, “good morning, innovation. Good morning, unequalled inspiration.”

Audi likes throwing down the gauntlet before its German rivals. The brand has taken on BMW several times. Audi actually staked its claim as the newest and coolest luxury brand several years ago with an ad that had an old rich man waking up to the grille of his big luxury car in his bed. It’s a knockoff of the horse’s head from “The Godfather.”

So who has the better shout? Both brands are growing fast, Audi sales rose 23% last year and Cadillac was up 35%. Cadillac sells almost 50% more vehicles. But in terms of burnishing the brand as the coolest newcomer, Audi has the edge. Its average buyer makes more money. The A8 is a legitimate competitor to the Mercedes S-class and BMW 7-series flagship sedans. Audi’s A4, which is smaller than the Cadillac CTS, attracts nouveau luxe buyers. Cadillac is still working on cars to battle it out in those two vital market segments. Plus, Cadillac marketers readily admit that they are trying to expunge the image of old, stuffy Cadillac. You have to appreciate the moxie shown by both brands.

It can only be a good sign that Detroit carmakers have the cash on hand to advertise in pricey venues like the Super Bowl. But in Chrysler’s case, the money for its “Imported from Detroit” ad for the new 200 sedan may have been better spent elsewhere. The commercial starts with gritty images of bleak urban ruins, smoke stacks and downtown Detroit set against a lead-grey sky. The narrator asks, “what does this city know about luxury?” As we see more images, rapper Eminem comes onscreen driving a Chrysler 200, which replaced the weak-selling Sebring sedan late last year. The opening riff to his tune “Lose Yourself” eerily starts in and Eminem cruises the city. By the end of the ad he walks into Detroit’s Fox Theater where a gospel choir is singing. He then points into the camera and says, “This is the Motor City. And this is what we do.” The imagery is nicely done and Eminem is cool, but this ad misses the mark for several reasons.

1. The 200 is the wrong car. No one confused the old Sebring with luxury and this car is an upgrade, but not a completely-new model. The 300 is Chrysler’s big, stylish, pseudo-luxury car for the gangsta set. No way Eminem drives a 200. His bag man probably wouldn’t drive a 200. The 300 would have been a better choice.

2. We didn’t see enough of the car. The ad is expertly shot and brings to life the idea of a tough and resurgent Chrysler and Detroit. It shows a side to the human side to Motown that most outsiders don’t know, but it shows so little of the car that it’s tough to conclude that Detroit, or more specifically Chrysler, can do luxury.

3. To the rest of the nation watching the Super Bowl, Chrysler is struggling to make it back and Detroit as a city has been left for dead. Trying to raise the prospects of both in one ad is, shall we say, extremely ambitious.

4. Troubled American car brands need to get away from gritty Detroit imagery. No one needs reminding that Detroit is a city in serious trouble and that two of the Big Three would have disappeared if not for a government bailout. Domestic brands have to change the conversation for generations of Americans who abandoned them years ago and for young consumers who don’t know them. Ford has been plugging quality and technology like Sync. Chevrolet and Buick have been talking about fuel economy, Bluetooth and 40-gig hard drives in the dash. Both ideas are getting traction.

Chrysler can boast that the 2-minute ad, which is long for a Super Bowl commercial, got the new car some much-needed attention. Auto research website Edmunds.com said that after the ad aired, 1,619% more people (about 8,300 in total) went to the site to look at the 200 than typically search for it on a Sunday evening. The problem with the comparison is that few people were looking at the car to begin with. Edmunds says that 681 people on average were shopping the car before the ad aired. An average of 15,911 typically shopped for the competing Hyundai Sonata. Will these new visitors buy the car? That will be the real test. The Sebring sold fewer than 25,000 cars last year. For comparison, Ford sold 219,000 of the competing Fusion. Chrysler got some sizzle with the ad, but there may not be enough substance to generate sales.

After my last missive gave a ‘thumbs down’ to Chrysler’s 200 ad, which aired during the Super Bowl, one reader asked for my take on Volkswagen’s “Darth Vader” spot for the Passat. Since more of you disagreed with my view on Chrysler’s Eminem ad than sided with me, I’m flattered. In VW’s ad, a young boy is marching around his house in a Darth Vader costume that must be the envy of the neighborhood. He tries to use The Force to get his dog to rise, open the dryer, move a sandwich across the counter, and all in vain. Finally, dad comes home in the Passat. Junior Darth starts with the Jedi gesticulations to get the car to do something. We don’t know what exactly. Dad uses remote start from inside the house to fire up the ignition. His son is shocked. He got the force to work. He thinks he started the car with Jedi mind tricks.
My take: It’s a great ad, and not just because I like John Williams’ score “Darth Vader’s Theme.” This ad is a lot of fun and shows once again that VW doesn’t take itself too seriously. VW’s marketing efforts have usually displayed some joie de vivre and consistently cast a fun image. They have done some more serious ads when talking about safety features, but generally VW’s marketing has been pretty loose. It’s a testament to VW marketing that the brand has so much recognition in the U.S., even though its actual sales presence is so small. About 19% of car buyers shop it, according to research firm Strategic Vision. But only 2% of Americans buy VWs. Fat sticker prices have long kept many buyers away. That may change as the new Passat starts around $20,000, which is a $7,000 drop from the last-generation car. Giving up so much price in the name of sales volume is a questionable strategy. For now, let’s stick to the ad. It was humorous and right for VW.
The Super Bowl is getting smaller in the rearview mirror at this point, but while I’m on it let me talk about one more ad. It must be said. Mini’s “Cram it in the Boot” ad was truly terrible. The theme is you can cram all kinds of things in the back of a Mini Countryman. But the fraternity house double entendre is beneath a car brand that has great cachet and appeals to a sophisticated buyer. They really missed the mark with that one.
