Electronic Jacquard

.Fully electronic jacquard with for fast fashions.It is fully computerizedSoftware program is given as input in m/c according to fabric design by using laptop.New patterns are transferred to the machine by the electronic control system in a matter of secondsThe electronic individual needle selection produces reliably without pattern errorsNeedle , jack & vertical sinkers are used here.

Parts Of Electronic Jacquard

GSM & GSM Control

m

GSM is a technical term that indicates the weight of the fabric per square meter GSM is a

buyer’s requirement; hence GSM control is very important.

In older m/c s is controlled by VDQ pulley. By rotating the upper disk in positive. Direction will reduce the pulley diameter and GSM will increase.

Pulley diameter Stitch length GSM Pulley diameter Stitch length GSM

In modern m/c GSM is controlled automatically by the help of variable rpm motor and relanit technology.

GSM & GSM Control

Relanit Technology

The technology of using vertical sinker in circular knitting m/c.

GSM can also be controlled directly by this sinker.

Reduce the possibility of sinker mark.

Reduce yarn tension during knitting

Types of stripe produced

Feeder stripe: - In this, stripe effect is produced by

using different color yarns in different feeder in an

orderly manner according to repeat.

Engineering stripe: - In this, stripe effect is produced

by gradually adding different colored yarn in each

feeding position according to repeat with the help of a

device called ‘finger mechanism’.

E-Stripe Circular Knitting M/C

Producing Feeder Stripe

m

Red = 5 courseGreen = 3 courseBlack = 2 course__________________________

Total = 10 courseWhile producing this fabric in a 54 feeder m/c active feeder would be = 10x5 =50The rest 4 feeder will be needle drop or, all miss cam.Yarn arrangement would be,

Feeder (1-4) = missFeeder (5-9) = RedFeeder (10-12) = Green Repeat Feeder (13-14) = BlackFeeder (15-19) = RedFeeder (20-22) = GreenFeeder (23-24) = Black. And so on.

Program for E-Stripe

Red = 10 course

Green = 5 course

Red = 5 course

White = 5 course

Pink = 10 course

White = 5 course

Red = 5 course

Finger1 = Red,

Finger2 =Green,

Finger3 =White,

Finger4 =Pink

Then Program will be:

Finger1 1-10

Finger2 11-15

Finger1 16-20

Finger3 21-25

Finger4 26-35

Finger3 36-40

Finger1 41-45

1. Plain single jersey

2. Single Lacoste

3. Double Lacoste

4. Polo pique.

The mostly produced double jersey derivatives are

1. 1 x 1 rib

Causes & Remedies of Knitting Fault

m

.

1.Hole Causes: Take up in improper tension Remedies: Adjusting proper take up tension

2.Knot: Causes: After thread breakage or bobbin end,

Twisting to join thread ends; therefore Hand dust get incorporated with yarn.

Remedies: Knotting should be done in proper way.


m

.

3.Dirty SpotCauses: Externally incorporated dirt, lint, grease etc . Remedies: By keeping the work place and m/c clean.

4.Sinker Mark:Causes: Due to sinker decayed.Remedies: Change the sinker.


m

.

5.Lycara Out

Causes: If lycra yarn missed or breakage happened.

Remedies: Operator should be more cautious to make

necessary adjustment or replacement or joining the lycra yarn.

6.Oil Spot: Causes: Excessive supply of oil at different friction

point. Remedies: Proper lubrication system is must.

collect the weak lye separately from

Presently they are using rain water in Boiler by

establishing rain water harvesting plant in their

complex. Their present storage rain water capacity

8389 m3. Their Treatment Capacity: 360m3/day.,

Their Present Rain water Catchment’s area

1,00,000 sqft, but we are thinking to increase

their catchment’s area up to 3,42,000sq.ft. We will

use this rain water in their dyeing process.

Kitchen waste recycling

• All kitchen wastes are collected and recycled to fertilizer which is used in the tea garden of SQUARE

Tea garden

They are progressing forward to considering

the concept of zero discharge, we have

already established caustic soda recovery

plant ( CRP) to recover the caustic soda from

waste liquor. They also developed some

infrastructure to recover salt and water

from dye.

Security

SKFL has its own security agency named Aegis

Central Yarn Store:

Capacity: Around 1200 Metric Ton.

In yarn store yarns are kept in cartoons.

Dye Stuff and Chemical store for Yarn Dyeing:This store situated in an extension room of Yarn

Store 1.

Spare Parts and Accessories Store:Different m/c spare parts and daily necessaries like

pen, stickers etc are kept in this store.

Grey Fabric Store:After Knitting fabrics are collected in roll forms,

then quality passed rolls are stored in Grey fabric
