BIOSCOURING
WITH SCOURZYME L : RESPECTS THE FABRIC, RESPECTS THE ENVIRONMENT
The
bioscouring process using Scourzyme L is an alkaline pectinase or
pectate lyase used to eliminate all the non-cellulosic material from
cotton fibre so as to increase wettability and ensure efficient dyeing
and to increase whiteness. It works by breaking down the pectin which
‘glues’ the waxes (fatty acids, alcohols and esters) to the fibre.
Scourzyme can eliminate up to 75 % of the pectin at a pH of 7.5-9.5
and a temperature of 25-60 degree centigrade.

COMPRESSIVE
SHRINKING RANGE
The
compressive shrinking range is an ideal solution for the finishing of
woven fabric, Denim and even for some delicate knitted fabric. The
compressive shrinking ranges comprise complete modules which can be
adapted exactly to the customer’s requirement.
Advantages
:
-
Optimum
compacting effect and minimum residual shrinkage, maximum
production speed with constant fabric quality.
-
Easily
programmable parameters such as pressure, temperature, steam and
speed lead to reproducible quality features such as residual
shrinkage, touch volume and shine.
-
Optimum
path prevents distortions, rolling edges and uneven compacting.
The
machine is from Buckner Group.

ELECTRONIC
DOUBLE NEEDLE BED WARP KNITTING MACHINE
It is
used to manufacture wide range of articles for technical use (netting
for sports equipment and the food industry, high resistance ribbons in
special fibres, ribbons and fabrics for applications in the
geo-textile, automotive, building and industrial sectors), for medical
uses ( tubular elastic netting, emergency bandages and dressing), and
for footwear ( three-dimensional fabrics for uppers). It comes in
gauges from 5 to 20 n.p.i. and has working width of 800 mm. It is
equipped with 8 electronically controlled pattern bars and can work on
any type of yarn, synthetic and natural.
It is
fitted with the Data Control – 3 Controller which allows for using
several devices with electronic control ( end-product, take-down,
feeders, etc. ). The presence of 2 needle beds and the unique
evolution of the pattern guide bars makes it possible to obtain
“double face” articles, with identical structure specifications on
both sides – no front and back side to the fabric. The machine
is Comez DN/EL-800-8B.

NATURAL
AS A MODEL FOR FINISHING TEXTILES
A
natural alternative to modern fluocarbon finishes, based on denrites
and produces water-repellent, oil-repellent and soil-resistant
effects. It is also made of Rucostar EEE. Ruco-dry renders a
fabric permeable to water vapour but impermeable to water. It is used
for sportswear and other goods. Bionik Finish Rudold can also be used
for sewing threads.

DGE
ENGINEERING : THE STAR OF TEXTILE DECORATION
The
French company DGE Engineering has developed a technique known as
Cristable Fabric Transfer, which involves producing decorative effects
on fashion items by means of transfer techniques. The techniques
include Cristable Decoupe, Cristable Vintage, Cristable Window,
Cristable Fashion and Cristable Remixe. The latter three techniques
involve : cutting a window into garment and creating transparent
effects (C. Window), sticking decorative tapes into fashion garments
without fraying or altering the fabric (C. Fashion) and an inlaying
technique for decorating leather or textiles.

APPLICATION
IN PROSTHETIC LIMBS AND CUT-PROTECTION SPORTSWEAR
SpectraCarb
allows professionals to shape and adjust the socket for a better fit.
It also procides a more flexible, comfortable socket for the
user; and a more cost-effective product for the manufacturer. It
protects prosthetic limbs from damage caused by sharp internal carbon
structures. The sock extends the life of the prosthetic limb saving
amputees and medical companies from the aggravation and economic cost
of frequent replacements. It eliminates squeaking noises that often
result from the constant motion of the internal carbon
structures during use.

WASHING-OFF
AGENTS FOR REACTIVES
The
washing-off of reactive dyes depends on : 1. Amounts of unfixed dye
present, 2. Ease of removal of unfixed dye, and 3. Tendency of unfixed
dye to stain unprinted parts. Sandopur RKSI Liq. Conc. is efficient in
the washing-off of hydrolysed reactive dyes. Sandopur WASH liq. is a
fastness improver for reactive sulphur and vat dyes on cellulosics and
their blends.

DYEING
OF LYCRA T-400 ELASTIC FIBRE
Lycra T-400 is a new
elastic fibre based on bicomponent technology, which offers improved
comfort, handle, wrinkle-resistance and easy-care properties in
knitted and woven fabrics. Lycra T-400 is normally dyed under HT
conditions at 130 degree centigrade. Good tone-in-tone dyeing of the
single components can be achieved at this temperature, without
significant loss of stretch recovery properties.
DyStar recommends for Lycra T-400.

CELLULOSE
ESTERS IN NON-WOVEN TECHNOLOGY
Cellulose esters can be
used as critical component in the manufacture of next-generation non-woven
products from fibre modification to converting and finishing. By
adding even a small amount of cellulose esters into the right
formulation, manufacturers can improve the feel, appearance and
overall appeal of non-woven products. On a non-woven bandage, the
cellulose ester film permits
moisture to escape, while allowing oxygen to assist in healing the
wound.

FRICTION-BASED
FABRIC QUALITY EVALUATION
METHOD
A
computer method had been developed that accounts for the complexities
involviong the frictional evaluation of textile and polymeric
materials. A simple parameter that takes into account the material and
surface properties has been developed and the calculation of this
parameter has been automated with the software. Friction plays an
important role in fabric manufacture, final quality and marketing. The
software automatically calculates the friction factor.
