SECTIONAL WARPING

Page 3: Warping

INTRODUCTION; Sectional warping is a warping m/c, where warp yarns of different quality are used for stripe or other warp variation in weavers’ beam. Direct weavers’ beam is created for loom-shed.( Sectional warping is preferred for strong yarns).

SIZING

Page 4: Warping

Objective: Sizing is specially applied to the woven fabric for the following purposes:

1) Increase it’s weavability

2) Increase the yarn strength

3) Reduce the yarn hairiness

4)Minimize the abrasion between warp threads and various loom parts, and between threads

that are adjacent to each other.

M/C NAME: BENINGER BEN-SIZETEC

No. of machines: There is basically one sizing machine. There is a Separate part beside the machine known as

Kitchen. It consists of:-

Mixer : Here basically the size ingredients are mixed with water. An optimum amount of

pressure and temperature is maintained here.

Total capacity= 56 inch (first 6 inch = 100 L, 1inch=25 L)

Cooker : Here the mixture is whirled around so that the size ingredients are properly mixed

with each other. Temperature maintained is 1200C and the material is processed here for

30min.(same capacity)

Storage unit: The mixture is stored here and sent to the main unit when necessary. The

material is kept here at 90c.(approximately same capacity

Optimum size percentage

The percentage size to be applied to a warp in order to achieve a minimum number of end-breaks during

weaving is dependent mainly on:

The end density, as this will affect the amount of end-to-end abrasion that will take place;

The linear density of the warp, which greatly influences the strength of the yarn and will also

affect the amount of abrasion; and

The pick density, which will affect the amount of abrasion between the warp ends and the reed

as it reciprocates.

There are other factors which may also need to be taken into consideration, such as the

fibre type, the yarn type, the yarn structure, the type of size and the type of loom.

DIFFERENT TENSION ZONES OF SIZING

TENSION ZONES: Tension imparted on warp yarns are implemented on different zones in sizing m/c. There are 5 zones in sizing m/c. Each zones have unique multiple factor, which are used to calculate the warp yarn tension.

WARP TENSION:= g/m*TENSION FACTOR

G/M = Total ends/ (1.693*count)

SIZE PICK-UP PERCENTAGE CALCULATATION

SIZE PICK UP PERCENTAGE: Size pick-up percentage is the amount of size paste attached to yarns after yarn is released from squeezing rollers.

SIZE PICK UP % = weight of size material /( Weight of unsized yarn)*100

CALCULATION: Net weight(sized yarn) =Gross weight – Tare weight

= 619.5 – 191.0 kg

= 428.5 kg

Weight of unsized yarn = (length*total ends)/1693/avg Ne

= 4508*6090/1693/45.96

= 352.82 kg

Pick up percentage = (428.5 – 352.82)/352.82* 100

= 21.4%

SIZING M/C TENSION CALCULATION

Sizing tension is calculated by multiplying factors of zone with gm/m. Calculated tension can be adjusted by 50N from fixed value.

Gm/m = Total ends/1.693/count = 42.15

WINDING ZONE TENSION : gm/m*16 = 575N (fixed = 680N)

CREEl ZONE = gm/m*6 = 252.9N (fixed = 300N)

PRESS ROLL = gm/m*14 = 590 (fixed = 590)

LOOMSHED

Introduction: Loom shed is the department where fabric is weaved in loom. Warp yarns are taken from weavers’ beam and weft yarns are inserted from another package.

FABRIC PRODUCTION PROCESS

DETAILS OF LOOM-SHED

DESIGNING DEPT. Fabric pattern, denting order and

pegging plans are made.

SAMPLING DEPT. A sample fabric is produced with

given preference, for testing

PREPARATORY DEPT. Warping, Sizing and leasing process

are done to assist weaving

LOOM-SHED Fabric produced by interlocking warp and weft yarns. Drawing & knotting will be required before fabric produced sometimes for

different quality

INSPECTION & DISPATCH. After production inspection for

fabric faults are done and mended. After that fabric is dispatched

Three types of shedding mechanisms are used:

1) STAUBLI CAM SHEDDING2) STAUBLI DOBBY SHEDDING3) FILTEXTILES DOBBY

Two types of knotting m/c are used:

1) TODO - 2 m/c2) STAUBLI -1 m/c

LOOM MECHANISMS

Primary motions: 1) SHEDDING 2) PICKING 3) BEAT UP

Auxiliary motions: 1) TAKE-UP 2) LET-OFF 3) WARP STOP 4) WEFT STOP

Page 15: Warping

PRIMARY MOTIONS

SHEDDING: Shedding is done either CAM or DOBBY mechanism. Shedding shaft gets movement from SUMO MOTOR(Picanol) or Main motor(Toyata, Sulzer). Heald frames are set as some difference for staggering.

PICKING: Picking is done by air-jet. Weft yarns are inserted by air pressure. There are two main valves and relay nozzles for continuity of jet integration. Main and relay valves are connected with main nozzles and relay nozzles.

BEAT UP: Beat-up mechanism get motion from crank drive connected by gear with main motor.

AUXILIARY MOTION

TAKE UP: Take-up motion is controlled by individual motor. Fabric is rolled on a cloth roll which is surface driven

LET OFF: Let off motion get control by individual motor. Let-off motion is assisted with easing motion where feeler rollers are vibrated to adjust warp tension.

WARP STOP: If warp ends get broken loom is automatically stopped by hydraulic brake. Warp stop motion is controlled by drop pins, when a warp breaks drop pin fall on a electrode, completing the circuit and making loom stop.

WEFT STOP: Weft stop motion is controlled by two filling detector (FD1 and FD2).

SELVEDGE : In air-jet loom dummy selvedge are used with leno selvedge. There is a leno box for every loom.

REED: For air-jet looms profile reeds are used for jet integrity.

LOOM PRODUCTION

Loom production determines the total production of weaving. Loom production data is stored and updated on spreadsheet and informed to MIS. Main hurdles of loom production are beam gating, knotting and warp stop and weft stop motion.

SOMETHING ABOUT THE SECTION

Each fault is given a marking. This marking technique varies from mill to mill. Here the marking technique is shown below.

Maximum points given to a fault = 4.There are corresponding marking of 1, 2& 3.

Maximum allowable points to consider a fabric as “A” grade is 24 within 100metres of fabric, for “B” grade this range varies for 24 - 90 within 100 meters of fabric. Above this it is considered as “C” grade fabric.
