Weaving : Weaving I a process by which weft thread are interlace with
warp thread to produce a product known as woven fabric , on a machine
called loom and process called Weaving.
Weaving
Machine : It is a machine in which weft thread are interlace with warp
thread.
Weave : It is a order of
interlace of warp thread and weft thread.
Or it is a
combination of interlacing in a particular manner or style.
·
Interlacing
decide by manuflating of ends.
·
Interlacing
perform by shedding mechanism
·
Interlacing
decide by lifting of heald frame
Type of
Interlacing :
1. Warp Over Weft : when the warp is lifted above the
inserted weft.
2. Weft Over Warp : when the weft is lifted above the inserted warp.
Weave
Repeat Unit : It is
a smallest unit of beam which repeat throw out the length and width of cloth.
It is decide
by lifting of heald frame.
Design
decide by following terms :-
i.
Lifting
Plan
ii.
Draft
iii.
Denting
Plan
i.
Lifting Plan : It
is a order of lifting or lowering of heald frame on each surfacing insertion of
picks.
It is decide order of
heald frame. In heald frame, each end pass through the each wire of heald
frame.
ii.
Denting Plan : It
is a order of passing ends to the dents of reed. In reed , one or more then one
ends pass through the dents of the reed.
iii.
Draft : It is
a order of passing the ends to the heald frame. That is known as draft.
Warp : The Longitudel thread which are parallel to selvedge which
are known as warp.
Weft : The transverse thread which are
perpendicular to selvedge or perpendicular to the warp thread which is known as
weft.
Crimp : The Waviness of the
yarn is known as crimp.
Identification
of Warp And Weft Thread :-
·
By
Selvedge.
·
By
observing the reed mark (Air Gap).
·
Warp
density is always
gather then weft density. Or EPI is always gather then PPI.
gather then weft density. Or EPI is always gather then PPI.
Warp Density >
Weft Density
