Fabrics Name : Interlock Fabrics
Introduction of Fabric :
Definition : Interlock means a device or mechanism for connecting
or coordinating the function of different components. a fabric
knitted with closely interlocking stitches allowing it to stretch.
Interlock fabric is a variation of rib knit construction. Similar to a
Jersey knit except both front and back of the fabric look identical.
Double knit construction makes this a thicker knit fabric. Interlock
is the tightest weave, gives the smoothest surface and the finest
hand. The fabric is extremely soft, firm and absorbent.
Characteristics of Interlock Fabrics :
Interlock the technical face of plain on both
sides so the appearance of face and back
The Wales of each side re exactly apposite
to each other and are locked together.
Widthwise and length elongations are
approximately the same as single jersey
The fabric does not curl at the edges .
The fabric can be unraveled from the
Two yarn must be removed to unravel a
complete repeat of knitted courses.
Fabric thickness is approximately twice than
that of single jersey .
Features of Interlock Fabrics :
I. They have an identical appearance on front and
rear surface they are double surfaced.
II. Pattern and surface designing is limited.
III. Front and rear surfaces are smooth.
IV. It has a dense structure.
V. Its stretching property is higher in lengthwise
than in breadth wise
VI. It has advanced dimensional stability and form
VII. Heaviest knitted fabrics can be obtained
compared to other single yarn knitted fabrics.
VIII. If subjected to tension loop can run off end to
IX. It provides a better heat insulation since there is
a layer of air between front and rear surfaces. It
keeps warmer compared to other single yarn
X. Humidity removal property of interlock knitted
fabrics is higher since it has a bulk
Machine requirement for interlock knit fabric :
Interlock fabrics are mainly produced on specially
designed circular double jersey machines called
They are high speed, multi-feeders with closed
cam track machines.
The common gauges for interlock fabrics are 20-
24 NPI, using 1/30 Ne cotton or 1/48 Nm worsted
Worsted interlock is for ladies’ winter suiting
fabrics. For those 28 gauge fabrics, the yarns
used are mainly textures polyester of 75 denier.
