No wrinkles, no yellowing: Paradox turns possible
Resil’s Value Plus System for white shirts explodes a myth
- that white shades and wrinkle-free finishing are incompatible. Additionally,
the Value Plus System guarantees a soft, smooth finish and easy application.
Finishing of garments for a durable ‘wrinkle-free’
effect was first achieved in 1987 and it was a revolution of the time. Today,
such finishes are much sought after, and no high flying brand is complete without
a wrinkle-free range in its showcase.
Wrinkle-free, not problem-free
Wrinkle-free finishing, nevertheless, has posed a problem
for experts in textile finishing from its initial days. The widely used chemical
DiMethylol DiHydroxy Ethylene Urea (DMDHEU) has a tendency to lend a yellow
colour to white garments, especially white shirts. Excessive formaldehyde vapours
as well as volatile acid liberated during DMDHEU application tends to change
shades, particularly by imparting a yellow effect on white and other light coloured
garments. Moreover, these garments lose a good amount of their initial strength,
reducing the durability of treated textiles. The desired properties of a soft
handle and brilliant lustre are also lost.
A sparkling, creaseless breakthrough
| From Resil’s research and innovation lab comes
a new softener - Resil Ramido. This is a highly versatile softner with added
benefits over organic softeners, and without the associated drawbacks of
foaming, odour, etc.
Resil Ramido is a fatty amide that is suitable as a hand modifier on
all types of substances. It imparts a bulky non-soapy handle when compared
to a conventional organic softener with much less foam during the process.
The outstanding feature of Resil Ramido is its compatibility with other
additives such as silicones without causing shade variation or yellowing.
The odour that is so typical of organic softeners is also absent, making
its application a pleasant experience.
Ramido’s performance on cellulosic, synthetic and protein-containing
substrates is found to be exceptional; imparting superior surface smoothness
and volume to the substrate. It is safe on dark shades as well. Resil
Ramido has been specially recommended in yarn finishing. An excellent
lubricant, it is effective at very low dosage without compromising on
important parameters like tensile strength.

A wrinkle-free finish on shirts without side-effects
remained a challenge, until Resil’s research team concentrated its efforts
towards perfecting this popular yet incomplete finish.
This resulted in a breakthrough development, a product
that achieves a lasting wrinkle-free finish while retaining whiteness. Resil
Value Plus System, the first comprehensive value package for a wrinkle-free
finish on white garments. At the heart of the Value Plus Package is Resil CLS
- a near-perfect improvement on the conventional DMDHEU cross-linking system.
A modified Glyoxal based, ultra-low formaldehyde linking system, it assures
all the benefits of the traditional method, while adding to the handle and shelflife
of the garment.
India’s first wrinkle-free shirts
Till now, marketers in India could only offer imported
wrinkle-free shirts, since there was no effective indigenous formula without
the associated problems. With the introduction of the Value Plus System, however,
Indian brands now have the opportunity to provide a world-class, homegrown wrinkle
free product.
A comprehensive, feature-packed solution
The Value Plus System is distinguished by three
key features:
- Very low formaldehyde content
- No loss of tear strength
- Easy application.
Moreover, it is a single, comprehensive solution that
addresses all aspects of wrinkle-free finishing: Handle, lustre, durability
and colour fastness. These multiple capabilities stem from Resil CLS’ being
an all-in-one resin, which offers better functionality than a conventional resin
in normal process conditions. Resil CLS does away with the need for an acidic
catalyst, polyethylene and even silicones at times; being a single component,
it makes for easier handling.
Compared to the DMDHEU system, Resil CLS ensures remarkably
low loss of strength, enabling an ideal application on lightweight garments,
shirts, shirting fabrics and knits. Its negligible formaldehyde content also
makes it an efficient master solution for pastels and whites.
The following are some of Resil CLS’ benefits
over the DMDHEU system:
- Soft, smooth handle with natural comfort and breathability.
Does not make the fibre brittle and stiff, hence, handle is not harsh.
- Good lustre, shade retention and brilliance in the
absence of acid-liberating catalysts and yellowing agents.
- Improved physical properties. Very low tear, tensile
and bursting strength loss combined with low frosting and crease edge abrasion.
- High compatibility with accessories like zippers
since acid liberation is absent.
- Easy application. Being an all-in-one component,
error-causing variables become redundant. Handling becomes a smooth affair.
- Long shelf life. Unlike other pre-catalysed products
that have a lower shelflife of 3-6 months, Resil CLS can be preserved for
a year.
Silicon research
Silicones, as a class of synthetic polymers, are extremely
versatile with over 4000 applications ranging from insulators and aerospace
applications to sealants and cosmetics. Resil is one of the few companies in
the world to dedicate itself to silicone research focused solely on Textile
Applications. In the textile applications segment, Silicones can be modified
with structural and functional modification in the base product to offer a myriad
range of finishes. Resil’s new polymerization plant allows us to design
siloxane molecules at the base polymer stage itself. Result: A range of specialty
silicone plymers that are designed for specific substrates.
Resil offers truly engineered products customised to
requirements. Distinctive fabric finish options are possible by the differentiated
use of silicones.
Speciality silicone formulations for :
- Polyester finishing
- Nylon microfilament fabric finishing
- Acrylic yarn and fabric finishing
- Antimicrobial finishing
- Wrinkle free finishing on garments
- Crease resistant finishing on fabrics.
ARC enables customers to reach out to the latest developments
in garments and finishing. Resil’s presence in key world markets and its
alliances with leading global players ensure a continuous inflow of information.
ARC will also serve as a conduit for guidance from
specialists in the various aspects of textile- and garment-processing. Contact
sessions and demonstrations will be conducted regularly, to provide an ongoing
interface between the customer and the technologist Resil’s Application
Research Centre excels in :
- Developing new finishes
- Customised finishes, combining diverse properties
- Finishes to match references
