INTRODUCTION

To survive and thrive in the competitive today’s business world, latest developments in

textile testing plays a vital role.

These high speed machines require much cleaner raw material, and therefore they

constantly challenge the testing machinery developers to provide faster and more

accurate testers and quality controllers

Textile industries need for analysis of any type of measurement like length, area, count of

any fine textile fiber can be done for textile fiber & fabrics to fulfill better quality of

products.

IMPORTANCE OF TEXTILE TESTING INSTRUMENTS

In the present textile scenario, textile materials should furnish better quality, good

aesthetic, durability and performance for user. Since for this, testing of textile materials

are significant to yield better quality and marketability

2

CLASSIFICATION OF TESTING INSTRUMENTS

Basically the testing instruments are classified into four categories

Fiber testing instruments

Yarn testing instruments

Fabric testing instruments

Multi-Purpose testing instruments

Other testing instruments

FIBER TESTING INSTRUMENTS

Fiber testing instruments are used to find or to determine the various properties of the

fiber such as staple length, fineness, nep count, strength, trash content etc. some of the

modern instruments available in the market are

Digi Vision Projection Microscope, Uster HVI 1000

YARN TESTING INSTRUMENTS

Yarn testing instruments are used to find or to determine the various properties of Yarn

such as twist, Strength, Elongation, RKM, Count, Evenness etc. some of the modern

instruments available in the market are Yarn Tension Meter, Digital Yarn Tension Meter,

Twist Tester (Single Yarn)

FABRIC TESTING INSTRUMENTS

Fabric testing instruments are used to find or to determine the various properties of the

fabric such as bursting strength, tearing strength, Tensile Strength, Darpeability, Air &

Water Permeability etc.

Some of the modern instruments available in the market are digital Mini-Martindale,

Dynamic Air Permeability Tester, Flammability Tester

MULTI-PURPOSE TESTING INSTRUMENTS

Universal testing instruments are used to find or to determine the various properties

are fibre, yarn and Fabric.

Universal Testing Machines

HVI 1000

It measures all the important quality parameters currently used by textile industries

such as Micronaire, fiber length, length uniformity, strength, color, and trash.

Additional information on short fibers, cotton maturity and sample moisture content

are also evaluated.

700 samples can be tested per 8-hour shift

4

USTER AFIS PRO 2

In Uster Afis Pro 2, any material in the form of bale, mat, sliver or roving can be tested

on the, repeatedly and reliably. Blends can be tested up to a ratio of 50% cotton: 50% synthetic.

FEATURES

Basic measurements of the NC Module include the amount of cotton fiber and seed

coat neps.

L&M Module measures fiber length and short fiber content, plus cotton maturity and

immature fiber content.

Trash Module measures the trash and dust content in cotton

Histogram Reports show the distribution of each fiber property compared to its size

group, visualizing the impact of a process on the fiber material..

5

DIGI VISION MICROSCOPE

FEATURES

Latest design computer interfaced projection microscope for fiber & yarn analysis.

With maximum resolution of 1500X magnification

Photos of all fibers longitudinal & cross-sectional view are loaded in software to

identify the fibers without prior knowledge in the same.

Various type of measurement like length, area, count of any fine textile fiber can be

done.

USTER TESTER 5-C800 (UT5)

Evenness %, Thick & thin places, neps are measured

Analysis of VL-Curves, Spectrogram.

With the special sensor technology, periodic or nearly periodic mass variations

caused by defective rotating machine parts (such as gears from the spinning pump)

can be detected with the spectrogram.

Operated at speeds up to 800 m/min with continuous adjustability

7

DIGITAL YARN TENSION METER

PRINCIPLE

Digital yarn tension meter has a specially designed electronic sensor which is

capable of sensing tension in the moving yarn very accurately.

This sensor converts the tension read by the sensing probe into the equivalent

electrical signal. This signal is processed through the micro-controller and the yarn

tension is displayed digitally in grams.

FEATURES

Capacity 0 to 200gms, accuracy 1gm.

Portable & handy can be carried anywhere.

Smooth precision-engineered mechanism

Latest model with sophisticated design

8

USTER TENSOJET 4

FEATURES

The high performance installation USTER TENSOJET 4 can carry out fully automatic

measurements with up to 30'000 tests – which means 24 km of yarn – per hour.

Spectrogram allows identification of periodic faults.

Fully automatic check of the whole measurement.

9

USTER TENSORAPID 4

FEATURES

USTER TENSORAPID 4 supplies all standard test values of tensile testing and provides

in-depth analysis of yarn quality.
