INTERLINING FINISH

AGES
Interlining and Cuff Fabrics
The interlining and cuff fabrics have to be imparted anti-shrink, resilient stiff finish. The recipe used must
ensure minimum shrinkage and loss in stiffness during washing at different conditions. Sanforizing of the
fabric before treatment will help in obtaining minimum shrink resistance and smoothness of the fabric
surface.

Addition of starch derivatives is also recommended for obtaining stiffness and addition of an optical
brightener in the finishing bath is recommended to improve the whiteness.
The effect on 100% cotton fabrics is found to be better than that on Polyester/Cotton blends.

The main function of interlinings is to maintain reasonably good dimensional stability of apparel clothing.
Generally, interlinings are made from fabrics consisting of cotton or spun rayon in warp and a rayon
blended yarn in weft. Interlining may be described as supporting fabric which must have good firmness,
and also the required elasticity and shape retention properties. These properties should remain intact
even when the fabric is subjected to washing and dry cleaning. Interlining fabric should have good resistance
to shrinkage.
The stiffening agent used for finishing interlining cloth should have ability to form an elastic and tough film
on the surface of the fabric. This film should withstand stresses caused due to repeated bending.
Cotton and its blends with polyester are generally used for collar interlinings which have to be resistant to
shrinkage, stiff as well as elastic. For washable apparels these properties should have considerable
permanency.

The selection of the stiffening agent depends on the properties expected from the finish which in turn
depend upon the end usage of the interlinings produced through such finishing.

A number of finishing products based on starches and starch derivatives, plastic dispersions, polyvinyl
alcohol, dimethylol urea and other compounds are available in the market. One can have a cost effective
result oriented recipe through judicious selection of such products depending on the end properties required
from a particular interlining finish. The above recipe is just an illustration only.
