Fabric Spreading: Fabric spreading means smooth lying out of
fabrics as per marker direction. Fabric spreading is the
preparatory process for cutting.
. Types of Fabric Spreading :The spreads can be of two basic
types: 1. Flat spreads :Here all plies are found of the same
length.2. Stepped spreadThis as the name suggests, is built up in
steps, with all the plies in one step having the same length. A
stepped spread is generally used when the quantities to be cut
precludes the use of a flat spread. The cut order plan details the
colors and ply lengths for a stepped spread, if it is needed.
Spreading Quality Specification : Spreading quality must be
measured with respect to the following factors: Ply alignment:
length and width Ply tension: stretch, slack edge Grain alignment:
bowing Splicing: waste and precision; Damage placement: economy of
placement; Surface direction; and Static electricity
Fabric Spreading Objective:To place a number of plies of fabric
under the marker according to the planning process. In the color
required Correctly aligned as to length and width At correct
tension
General Fabric Spreading System :
Mark the Splice Zone on the Spreading Table Use Paper for the
first ply in case the table surface is rough or when fine fabrics
are being spread Identify the defects noticed in the fabric by
means of sticker Use lubricated paper for separating layer To
prevent scorching in the natural fibers (coarse fabrics). To
prevent fusing in the synthetic fabrics. Ensure that decided number
of ply count and height of the spread is achieved.
How to spread:Pull the fabric to far end position Position the
fabric at the far end (with our without weight or pins) Align the
ply (width on one side Cut the ply after each layer. Repeat this
process from until the entire roll is spread Check ply count.
Forms of Spreading:
Cuttining are of Two kinds.
1. One Way Cutting : One way cutting is when fabric is laid the
same way up with grain or print pattern running in the same
direction. Fabric has to be cut at the end of each ply.
2. Face to Face Cutting: Face to face cutting is when the plies
are laid in pairs face to face. The grain or pattern runs in the
same direction.
.
Requirements of Spreading Process: Alignment: Elimination of
fabric defects/flaws: Correct ply direction: Correct ply tension:
Avoidance of distortion in the spread during cutting: Fabrics must
be flat and free from any crinkle & crease: Checks and stripes
should be matched .
Spreading Modes:Direction of Fabric Nap: A second consideration
in selecting the spreading mode relates to the direction of the
fabric nap. Placement of the nap may be nap-one-way (N/OW) or
nap-up-and-down (N/U/D). Direction of Fabric Face: The fabric face
may be positioned in two ways: face-to-face (F/F) or with all plies
facing-one-way (F/O/W), face up or face down
Fabric Put-up and Spreading Modes:Fabric Put-up; Open and Rolled
:
Fabric Put-up; Folded and Rolled :
Fabric Put-up; Tubular Fabric Rolled :
Spreading Mode; Open Fabric, Face One Way, Nap One Way (F/O/W,
N/O/W) :
Spreading Mode; Open Fabric, Face One Way, Nap One Way (F/O/W,
N/O/W) :
Spreading Mode; Open Fabric, Face to Face, Nap One Way (F/F,
N/O/W) :
Spreading Mode; Open Fabric, Face to Face, Nap Up and Down (F/F,
N/U/D) :
Spreading Mode; Folded Fabric, Face to Face, Nap One Way (F/F,
N/O/W):
Spreading Mode; Folded Fabric, Face to Face, Nap Up and Down
(F/F, N/U/D):
Spreading or Laying:
Types of Lay Plan :Half Garment Lay includes only half of the
garment pieces for example one side left or right. Generally used
for tubular fabrics. Whole Garment Lay includes garment pieces,
left and right sides. Generally used for Open width fabrics. Single
Size Lay is used using all garment pieces of one single size.
Disadvantageous as the consumption of fabric is higher.
Types of Fabric Lay: According to the construction fabric lay is
two types. These are:1. Straight lay2. Stepped lay According to the
direction of spreading fabric lay is three types. These are:1. From
right to left2. From right to right3. Zigzag lay
Straight Lay:
Stepped lay:
From right to left:
From right to right:
Zig - zag lay:
Removing Tension in the Lay: 1. An essential element of
spreading is to relax tension in the fabric during the 2. Spreading
process. Should there be any significant stretch in the fabric
after 3. Spreading, when the fabric is cut into parts, each part
will shrink. Even 5% shrinkage is enough to change a whole garment
size
The Method of Fabric Spreading:
a- By HandFabric roll is spreaded on the table by two laborers
according to the length & width of marker. Sometimes it is done
by entering a rod which is made by wood or metal in the center
paper table which is present in the center of the fabric roll.
b. By hook
In this process the top of the table on which the fabric is
spreaded is set at 10 angle perpendicularly.
c. Spreading truck with the help of operator:
There is a spreading truck on the one end of the spreading table
in which the fabric roll is placed.
2. Mechanical method: a. Semiautomatic Spreading machine is run
on the rails which are placed at two side of fabric spreading table
surface and operated by motor. Fabric roll is set in a
predetermined place of the machine.
b. Full automatic: This is the improvement of semiautomatic
machine.
