Eco-testing/

Pollution

Control

It is likely that

amines which are

declared as `safe’

may contain a

banned amine or

heavy metal

introduced during

manufacture of

compound. Such

`phantom’ impuri-

ties may go

undetected till dyed

fabric is tested. At

that stage it is

difficult to deter- mine source of

impurity. Hence,

main objective is to

develop impurity

profile of amines

which are not

banned. By

creating this

impurity profile

processor will be

provided with the

list of safest eco-

friendly dyes

covering entire

range of hues.

Detailed list of

intermediates used for

disperse and acid dyes

was prepared and the

routes of synthesis,

starting materials,

conditions of reactions,

etc., were compiled.

Characterisation of these

intermediates was carried

out by instrumental,

chemical & physical

analysis techniques.

Physical tests like melt-

ing & boiling points of

intermediates were

determined experiment-ally & % purity of some

amine based inter-

mediates was determined

by nitrite value method.

Characterisa-

tion study of

intermediates

can be used for

tracing out  the

possible sources

of impurities

such as heavy

metals, amines,

etc., in the

dyestuffs. Using

this data,

processors can

select safe dyes

& thus meet

export require-

Rheology of various

thickeners,viz.,Indalka

AGBV,Tamarind(TKP)

Starch,CMC & synthe- tic thickener & their

mixtures was studied.

Comparative printing

trials with disperse dye & diff.thickener compo- sitions were carried out & relation between color yield & composi- tion was studied.

Printed,steamed and

washed samples were

evaluated for K/S values (color yield), bending length (stiff- ness),& crock fastness

properties. From this

study it was found that

mixtures containing

starch show poor color

yield.However,AGBV:

TKP mixture shows

comparable color yeild.

Suitable chemical

modification of TKP

including de-oilation,

has been carried out

using diff.techniques.

Further,shear thinning

behaviour of modified

TKP,which was

improved using these

products was

compared.

Experiments

show that

partial & full

replacement of

gum by modi- fied TKP is

possible and the modified thickener composition gives com-

parable results in terms of color yield & brilliancy of print. Cost of printing can be controlled using this

alternative

thickener. It

was found that fullreplacement of guar gum is

possible by

sector for

Fabric samples using various combinations have been prepared using polyester, microdenier, viscose, cuprammonium, poly-urethane,

diacetate, etc. and their comfort related properties were assessed.

Silk fabrics possess good lustre, soft feel, superior handle and comfort in wear. On the other hand, these fabrics have some limitations like less durability, poor abrasion resistance, poor anti-crease properties, and high price, whereas polyester fabrics are durable, crease resistant, possessing easy wash and wear properties and comparatively cheaper. Therefore, in order to exploit the properties of both the polyester and silk yarns, the union woven fabrics using polyester and silk yarns were developed. As the characteristics of diacetate rayon is more similar to that of silk, the union woven fabrics using polyester and diacetate were also developed. Apart from that, various fancy union fabrics were also developed using different types of new combination of yarns such as texturised polyester, lycra, nylon, etc. The above work provided new product types and range.

MANTRA develops formaldehyde-free finishing recipes using formaldehyde scavengers. The addition of formaldehyde scavengers such as citric acid and urea give good results with an almost negligible increase in yellowness. In case of commercial non-formaldehyde finishing agents, there is no yellowing of the treated fabrics. However, the required degree of stiffness of finished fabrics is not obtained. Viscose and polyester/viscose give reasonably good easy-care properties with the non-formaldehyde finishing agents. In case of cotton and tencel, low formaldlehyde finishing gives the best results.

Processing of viscose filament and modal yarns poses problems like crease, fibrillation, shrinkage and

dimensional stability. Also uneven, patch and faulty process occur due to faulty

preparatory process. The scope is to develop suitable processing technology to cover these defects and improve the quality of fabrics which are used mainly in garments which has tremendous export potential.

Surat being a hub for sarees and dress material and is producing viscose varieties for domestic and export market. But for the better  growth in niche high end segments and to boost exports, special care is required in manufacturing and chemical processing of regenerated fibre (VFY) and new varieties of regenerated viscose like Modal (HWM) and lyocell fibre. All these regenerated fibres have some limitations. All these limitations are addressed in this present study and the precau- tions are highlighted for manufacturing and processing route and selection of machineries are also studied and following conclusions are made.

1

Baseline survey has been conducted to assess the quality vis- a-vis defect cause analysis of VFY fabrics produced in Surat. Based on observation, special cases & changes required during yarn preparatory process were studied to bring down defects in grey fabrics.

Dimensional stability and shrinkage control is very much impor-tant in case of VFY fabrics. Experimental trials of VFY fabrics (popular varieties) were conducted in soft flow U-tube machines and soft

Flow long tube

Machines, the results were also compared with “Conventional tapela processing”.

 

 

 

1

After assessment and thorough study of VFY, we have optimized the factors like tension, speed at yarn preparatory and weaving stage and we also suggested remedial measures to minimize defects like warp and weft strikes, pattas, thick & thin, etc., and demonstrate the ways to produce quality fabrics.``

3

For `shrinkage

Decrease’ of VFY yarn to meet stringent export demands and as per the global

Requirement in

Manufacturing of

Garments, experiments in

Chemical finishes

with DMDHEU resin were also carried out and boiling water

shrinkage (ISI-1299

method) and other

properties were

evaluated.

2

Viscose is very prone to crease and has low wet tenacity. Ceasing problem can b e resolved by proper selection of the machine like long tube soft flow dyeing machines with gentle action of flow water and fabric movement by reel.

Chemical processing parameters were

Optimized for the

Modal fabrics, using jigger machine.

 

 

 

3

Excessive shrinkage to the extent of 15- 16% in the grey fabric can be further controlled by treat- ment with cross linking resin and proper selection of catalyst with the commercial acceptance limit of 4-3.5%,. This probably is due to formation of greater no. of covalent bond.

5

Chemical processing

Parameters for excel

Fabrics were

optimized on Jigger.

4

Strength loss is also significant. It is likely that energy of bond formed compensates for that caused by dis- ruption of the hydrogen bond.

5

Being viscose the amorphous fibre, the strike rate is very high. It may cause uneven dyeing. Guideline is given in suggestion section to control the same.

In order to prepare the required anti-allergenic fabrics, commercial samples of such fabrics were procured from National Allergy Supply Inc., USA. Besides this, locally available bed sheets with a high thread count were also procured. All these fabrics were analysed for mechanical parameters such as reed/pick, weave, denier, fabric composition, etc. Based on these results, fabrics were woven with the required thread count & pore size. These fabrics included 100% PET

(3 varieties of thread count – 230), 100% cotton

(2 varieties, thread count - ~ 200) and PET/COT blend (2 varieties, thread count

~ 230). All these fabrics were given adequate pre- treatment & then finished with anti-bacterial & water- repellent finishes. Finishing was done by padding method & samples were cured on Rotolabo coating machine.  All fabric samples were analysed for (i) mechanical properties; (ii) air -permeability; (iii) water vapour transmission;

(iv) spray test for water repellency; (v) anti-microbial properties.

The barrier fabrics developed in this project have the requisite properties of a high thread count (small pore size), anti-microbial effect and comfort properties. The test results of air permeability and water vapour transmission are indicative of the comfort properties. The fabrics developed in this project can be used effectively as barrier fabrics for hospital bed sheets, surgical gowns, etc., as well as in applications which require protection from microbes.
