What is Ultra-fine fiber ? What is Microfiber ? Novelty fibers.

Ultra-fine or microfibers were developed partly because of improved precision in

engineering techniques and better production controls, and partly because of the need for lightweight, soft waterproof fabrics that eliminate the more conventional coating or lamination processes. As yet there are no universal definitions of microfibers. Textile Terms and Definitions simply describes them as fibers or filaments with linear densities of approximately 1.0 dtex or less. Others  have used such terms as fine, extra-fine and micro-fine corresponding to linear densities

ranging from 3.0 dtex to less than 0.1 dtex. They are usually made from polyester and nylon polymers, but other polymers are now being made into micro-fibers. The

Japanese first introduced microfibers in an attempt to reproduce silk-like properties

with the addition of enhanced durability. They are produced by at least three established methods including island-in sea, split process and melt spinning

techniques and appear under brand names such as Mitrelle, Setila, Micrell, Tactel and so on. Once in woven fabric form their fine diameter and tight weave allows up to 30000 filaments cm-2, making them impermeable to water droplets whilst

allowing air and moisture vapor circulation. They can be further processed to enhance other characteristics such as peach-skin and leather-like appearances. The split technique of production imparts sharp-angled edges within the fiber surface,

which act as gentle abraders when made into wiping cloths that are used in the

optical and precision microelectronic industries. Microfibers are also used to

make bacteria barrier fabrics in the medical industries. Their combined effect of low diameter and compact packing also allows efficient and more economical dyeing and finishing.

Finally, constant pressure to achieve and develop even more novel applications

of fibers has led to a number of other and, as yet, niche fibrous products. In principle,

the new ideas usually strive to combine basic functional properties of a textile

material with special needs or attractive effects.

What is Tencel ? How made Tencel ?

Lyocell is the latest addition of the series of regenerated cellulosic fiber. Commercially it known as Tencel. It has all conventional properties as like viscose in addition to its much praised encironmentaenv friendly production medhod. The solvent used is based on non-toxic N-methyl moepholine oxide used in a recycleable closed loop system, which unlike the viscose process avoids discharge of waste. Highly absorbent derivatives  of Tencel known as Hydrocell are establishing a foothold in wound dressing and other medical-related areas of Textiles.

What is Textile Testing ?

When you put on clothing, you want it to feel good against your skin. And you don't want it to contain harmful substances. But how to we ensure textiles are safe? Textile companies and consumer agencies conduct many kinds of analyses to make sure our clothes and the fabrics we use in our homes won't harm us, will be comfortable and will stay colorful for a long time. These processes are called textile testing.
Textile testing is the term for a whole series of tests that examine the physical, mechanical and chemical properties of textiles.

Technical or industrial textiles: what’s in a name ?

textile.technology blogger basic by Hasan
Technical or industrial textiles: In a name:

For many years, the term ‘industrial textiles’ was widely used to encompass all textile
products other than those intended for apparel, household and furnishing end-uses.
It is a description still more widely favoured in the USA than in Europe and
elsewhere.
This usage has seemed increasingly inappropriate in the face of developing applications
of textiles for medical, hygiene, sporting, transportation, construction, agricultural
and many other clearly non-industrial purposes. Industrial textiles are now
more often viewed as a subgroup of a wider category of technical textiles, referring
specifically to those textile products used in the course of manufacturing operations
(such as filters, machine clothing, conveyor belts, abrasive substrates etc.) or which
are incorporated into other industrial products (such as electrical components and

cables, flexible seals and diaphragms, or acoustic and thermal insulation for domestic
and industrial appliances).
If this revised definition of industrial textiles is still far from satisfactory, then the
problems of finding a coherent and universally acceptable description and classification
of the scope of technical textiles are even greater. Several schemes have been
proposed. For example, the leading international trade exhibition for technical
textiles, Techtextil (organised biennially since the late 1980s by Messe Frankfurt
in Germany and also in Osaka, Japan), defines 12 main application areas (of which
textiles for industrial applications represent only one group):
• agrotech: agriculture, aquaculture, horticulture and forestry
• buildtech: building and construction
• clothtech: technical components of footwear and clothing
• geotech: geotextiles and civil engineering
• hometech: technical components of furniture, household textiles and
floorcoverings
• indutech: filtration, conveying, cleaning and other industrial uses
• medtech: hygiene and medical
• mobiltech: automobiles, shipping, railways and aerospace
• oekotech: environmental protection
• packtech: packaging
• protech: personal and property protection
• sporttech: sport and leisure.
The search for an all embracing term to describe these textiles is not confined to
the words ‘technical’ and ‘industrial’.Terms such as performance textiles, functional
textiles, engineered textiles and high-tech textiles are also all used in various
contexts, sometimes with a relatively specific meaning (performance textiles are
frequently used to describe the fabrics used in activity clothing), but more often
with little or no precise significance.

Polyester Filament Yarns | Polyester DTY

Polyester Drawn Textured Yarn (DTY)

Drawn Textured Yarn (DTY) yarn is obtained when Polyester POY is simultaneously twisted & drawn. DTY yarn is mainly used in weaving & knitting of fabrics for making clothes, home furnishings, seat covers, bags and many other uses. DTY yarn can be in Semi Dull or Bright or Trilobal Bright depending upon the type of sections of filaments.

Technical Properties of DTY yarn can be molded in several ways to make the yarn suitable for its vast uses. Different heating techniques can be used to make the yarn set for specific use - 1 Heater DTY is normally woolly & more stretchable as compared to DTY with 2 Heater. Also the DTY yarn can be made with several combinations of Intermingle points - it can be Non-Intermingle (NIM) having 0 - 10 knots/meter or Semi-Intermingle (SIM) having 40 - 50 knots/meter or High-Intermingle (HIM) having 100 - 120 knots/meter. These knots are not actually the knots tied when two threads are broken but they are the tangle knots created by heating pressure. These Intermingle yarns, also known as Interlaced yarn, are the replacement for lightly twisted yarns. Polyester DTY yarn can also be twisted to high twists like 1500 TPM or 4000 TPM (twist per meter). Such twisted yarn can also be heat-set to make the yarn permanently thermo-set the twist. Catonic DTY is another variant of Polyester DTY that is mainly used in blankets. Catonic DTY is made from Catonic PET Chips.

Polyester DTY yarn can also be obtained in various colors by the dope dyed technology or by conventional dyeing. Dope dyed DTY is usually packed on paper bobbins whereas Raw White DTY that will be used for dyeing is loosely packed on perforated plastic tube so that all the yarn can be easily dyed when the bobbin is dipped in color. DTY is mainly produced in large quantity in China, India, Taiwan, Indonesia & Malaysia and is exported world-wide

Difference between Denim &  Jeans

Denim is a sturdy cotton warp-faced textile in which the weft passes under two or more warp threads. This twill weaving produces a diagonal ribbing that distinguishes it from cotton duck.

Jeans is one type of garment, which is normally used by the all aged people today. For the first time, jeans garments introduced by Levi Strauss as a copper riveted cotton trouser in the second half of the 19th century.

S.I	Denim	Jeans
1	Denim is one kinds of fabric name which can be made from 100% cotton twill or Stretch twill.	Jeans is one type of garment which is made by using denim fabric.
2	Denim is a fashionable fabric, by which different types of garments style can be produced.	Jeans is only a particular style of garments.
3	Denim can be defined either jackets, skirts, pants, shorts etc.	Jeans is specially defined at denim pants.
4	Denim is used not only for making pants but also for jackets, skirts, shorts etc.	Jeans is such type of garments which is made only from denim fabric.

What is Denim and How is it Made ?

Denim is a durable cotton twill textile, typically used to make jeans, overalls, and other clothing. To create denim fabric, the weft (horizontal threads) passes under two or more warps (vertical threads) threads. This process makes diagonal ribbing of denim that distinguishes it from cotton duck, another twill fabric.

On the other hand, Denim is a sturdy cotton warp-faced textile in which the weft passes under two or more warp threads. This twill weaving produces a diagonal ribbing that distinguishes it from cotton duck.
