Using combination technique, following types of newlook false-twist textured yarns were developed,viz.,normal dyeable and cationic dyeable poly combination textured yarns having novel pebble-like appearance, semi-dull poly &bright poly.were textured to
prodduce textured yarn with diff.lustre,normal den.poly & microden. poly.were also textured to develop textured yarn with soft feel; and also nylon & diff.types of poly.yarns such as bright, semi-dull and cationic dyeable were textured to produce nylon- poly. combination yarn having combined property of nylon & poly.. Single tex.poly. yarns having intermittent twisted appeance were developed and when it is used in fabric as weft gives grainy look and diff.feel.Properties of above- developed yarns were studied for para meters like D/Y, etc.It is seen that they can be used for sarees & dress materials.

were tested & analysed for
short term toxicity.Above
study shows that certain
common auxiliaries,viz.,non ionic/anionic surfactants,
binders,benzene based pro-
ducts,napthalene,sulphonic
acid based products,cetyl
alcohol based products,etc.
which are being used in tex.
processing of synthetic
textiles, are highly toxic for
fish. Bio-assay study of anti-

effect of diff.pathogenic
micro-organisms,viz.E-coli,
E.Klabsiella,Pneumoniae,
Stapaureus,baceilus subtills,
etc.on anti-bacterial finished
fabrics were carried out.
Durability of anti-bacterial
finish towards wash & wear
was studied.Also,certain
chemical compounds were
identified & studied as anti-

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.

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

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.

Benefits of both soft and hard friction
discs can be obtained
from a single twisting unit. It is possible to run twisting unit at a commercial speed within the range of normal parameters.
Development of novel stack disc
friction unit in case of hard & soft
material combina-
tions, the torque
transferred in the yarn may have increased as compared to 100% hard material friction disc unit. So, lower D/Y ratio can be used. Hence, reduces energy consumption and noise level.

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.

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”.

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.

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.

awaiting their response.
* Since no response was received from M/s Shell Co., correspondence has been done with Product Marketing Manager of M/s DuPont India. He has arranged 10 kg of DuPont Sorona (PTT) fiber from their agent in Korea, which will be received by 1st week of February.
Under this project, an HTHP beaker dyeing machine is required. For this, quotations from two companies have been received.
To create awareness about PTT fibers, we have conducted a half-day seminar on PTT fiber in collaboration with M/s DuPont India.
