How to know own mobile number (Airtel, Banglalink, Citycell, Grameenphone, Robi, Teletalk)

Forget your own sim number ? Don't have enough balance to enquiry ? Lets see how to know own mobile number including Airtel, Banglalink, Citycell, Robi, Teletalk.

Airtel, Banglalink, Citycell, Grameenphone, Robi, Teletalk

When i was using cellphone for first time, recovering mobile number or getting own number (if anyone forget) was not so easy. You must had balance in your sim and the minimum volume to be recharge was 300 BDT. Wasn't the amount costly? But this is end of 2013 :) Now a days it's an easiest method.

Say, you've found your lost sim or you have more than two sim cards and forget the number of the sim. On the other hand you have not enough balance in your sim that you can call your friend's mobile to know the number.

So, these hidden code must be helpful for you in that case. Type the following code and press dial button.

CALCULATION OF GSM

Learn Apparel Merchandising,
Dear All,

GSM means the weight in gram per square meter of fabric.GSM is a very important parameter for specified a certain quality of knitted fabric. The production of knitted fabric is calculated in weight. The GSM cutter is very popular and easy usable GSM testing instrument used in most knitted factory. But the construction of this cutter is very simple. It is circular disk of 100 square cm area with sharp blade attached to its edge. So 100 square cm of fabric can easily cut by it and weighted at the electric balance to get GSM reading.

There are two formulas for calculating the GSM of a knitted fabric

First formula is as under:

Course per inch X Stitch length X 39.37 X 39.37 X Tex

GSM = ----------------------------------------------------------------------

1000 X 1000

aNd

WPI X CPI X SL(mm)

GSM = ----------------------------- X 0.9155

Count(Ne)

CALCULATION OF WALES PER INCH (WPI):

We calculated the number of Wales in 10 inch fabric unraveling the yarn. Then we divide the no of total Wales by 10 inch to getting the Wales per inch.

CALCULATION OF COURSE PER INCH (CPI):

We calculated the number of course in five inch with the help of counting glass and needle. Then we divide the total no of course by five inch to getting the course per inch.

MEASUREMENT OF STITCH LENGTH (SL mm):

Stitch length is theoretically a single length of yarn which includes one needle loop and adjacent needle loops on either side of it. Loop exits in course in course length and it is that which influence fabric dimension and other properties including weight.

In order to determine the stitch length, we count 100 no Wales or stitch and count its length by hanging the yarn on the stitch counter. The reading is found in mm unit.

MEASUREMENT OF YARN COUNT:

We have fallowed a different way to find out the count of the yarn. At first we unravel a considerable no yarn from the fabric. Then we measured the total length of the yarn and measured the weight of that no of yarn. From these weights, we find out the count of the yarn.

The equation we followed is as follow:

N x L x 453.6

Count = ----------------

Wt x 36 x 840

Where,

N = number of yarn in bundle.

L = length of yarn.

Wt = weight of yarn.

Another formula is the following:

Ks x Tex

GSM = ---------------------

Stitch length (mm)

Where,

Ks is a constant. Its value is different for different fabric structure and fabric type. Ks is calculated and estimated as below:

GSM x Stitch length

Ks = -----------------------------

Tex

How do calculate Kg from Yards (Knit fabric)

From this post we will learn how to calculate Kgs from Yards.

Say,

Fabric length - 3.3611 yards ( 121 ")
Fabric Width - 45 "
Fabric Gsm - 140

Rules:

= Fabric length X Fabric width X GSM / 1550 / 1000

= 121" X 45" X 140 /1550 / 1000

= 762300 /1550 /1000

= 0.49180645161 kgs (weight of the followings fabric)

Hope above information will help you.

Costing Format of Garments

Dear All,

During the costing or pricing some times we forgot to include the cost of some small items. Which can be harmful for the manufacture as well as for us. But if we have any format of costing then the percentage of mistake (during the costing) can be reduce.

So, today I'm publishing a format of cost sheet for all of you. Please find below the format of cost sheet.

Due to some technical problem of internet at present I'm unable to upload the file in excel format. So, you will get the above format now in JPEG.

If any one want to get the "costing sheet" file in excel format then please mail me with the subject "Costing format". Please also must introduce yourself in the mail. I will send you excel file of costing format

Calculate the consumption of knit garments

sing,

Dear All,

For calculating the consumption of your knit garments pls follow the below instruction. The following information you need at first, as listed below:

(During the consumption pls used measurement of middle size for calculation or used the size which have most of the qty. If the style have 6 sizes then used size number 04 for consumption. Here we will consider the size: "L" for calculate the consumption)

i. Body length of the garments in cm. Say it is - 73 cm

ii. Sleeve length of the garments in cm. Say it is - 19.5 cm

iii. Approximate sewing allowance at body hem, shoulder joint, sleeve hem & armhole joint (in cm). Say it is - 10 cm

iv. Chest width (1/2) in cm. Say it is - 52 cm

v. Approximate sewing allowance at both side seam (in cm). Say it is - 4 cm

vi. Fabric GSM (finish). Say it is - 160 gsm

vii. Approximate fabric wastage in various stage. Say it is - 10%

(In this regards pls note that, fabric wastage depend on how many additional elements the garments have,which may changed in any time.If the garments has rotary print, enzyme stone wash etc than the fabric wastage will be more than normal wastage)

If you already have all the above information then,now just put the following information and get the fabric consumption.http://knitgarmentsconsumption.blogspot.com/ otherwise you can follow the below rules

Rules:
{(B/length + S/length + Sewing Allowance) X (1/2 Chest + Sewing Allowance)}X 2 X GSM X 12 / 10000000 + Wastage

= {(73 + 19.5 + 10) X (52 + 4)} X 2 X 160 X 12 / 10000000 + 10%

= (102.5 X 56) X 2 X 160 X 12 / 10000000 + 10%

= 5740 X 2 X 160 X 12 /10000000 +10%

= 22041600 / 10000000 + 10%

= 2.20416 + 10 %

= 2.424576

= 2.43 kg per dozen. (Consumption)

Hope everything is now clear to all.

Woven fabric consumption formula.

Learn Apparel Merchandising,
Before calculate the woven fabric consumption, you must need the followings information as mentioned below:

1) Measurement chart with technical spec.
2) Style Description.
3) Fabric Description.
4) Fabrics width/weight.
5) Washing shrinkage if any.

This formula is as under :
Formula = Length X Width / Fab width X Fab Unit

Here,

Length = length of the specific parts + allowance

Width = width of the specific parts + allowance

Fab width = Fabric width ( after considering the shrinkage

allowance).

Say, fabric width is 45" & the shrinkage

allowance is 1", Then the Fabric width will

be (45"-1") = 44" in the formula.

Fab unit = Fabric calculation unit, here it will be 36 because

we are going to calculate the consumption in

Yards.

Now we will calculate the consumption of a Shirt (front part)

Center front length = 32"+1" (Sewing allowance) = 33"

Width (Chest) = 24" + 1" (Sewing allowance) + 3"

Pleat.W (1.5X2) = 28"

= Length X Width / Fab width X Fab Unit

= 33" X 28" / 44" X 36"

= 924" / 1584"

= 0.5833333

= 0.59 Yards. (for front part)

How produce Yarn from cotton?

Dear all,

The yarn making process is a very complicated process. So many things are related with this yarn producing process. Moreover, various kinds of yarn are producing everyday all over the world.

These yarn can be divided by the types of raw materials which we used for making the yarn.
Such as-

100% cotton yarn.
CVC yarn (In this type of yarn the combination of cotton of polyester can be varied depending on the buyer requirement. such as - 65% cotton + 35% polyester, 60% cotton + 40% Polyester etc.Also mainly in this type of yarn the cotton part is always remain greater than the Polyester). CVC mean cheap value cotton.
100% polyester yarn.
PC yarn (In this type of yarn the cotton part is always remain less than the Polyester). PC means Polyester cotton.
100% Viscose yarn.
Grey Mélange yarn. In this type yarn we used a mixer of cotton & viscose. The percentage of cotton & viscose may vary depends on the requirement of buyer. Such as - 85% cotton + 15% viscose (Dark Grey Mélange), 90% cotton + 10% viscose (Grey Mélange), 95% cotton + 5% viscose ( Light Grey Mélange), 98% cotton + 2% viscose (Ecru Mélange) etc. Please note that if we increase the percentage of viscose then the yarn shade also will become dark accordingly. The percentage also can be 80% cotton + 20% viscose. So, if your buyer asked you for Grey mélange fabric then you must confirm it from them that, which percentage of viscose actually they looking for. The yarn price of Grey Mélange is higher than normal cotton yarn. Please always be aware about one thing that, the fabric which knitted by grey mélange yarn is not need to dyeing. Also fabric properties of cotton & grey mealange are almost same. So, we can used same care instruction for both (cotton & g.melange) type of fabric.

Other than these, many more kinds of yarn are producing in this textile world. Such as Bamboo yarn, Organic cotton yarn etc.

We can also separate the yarn by their finishing quality:

Combed Yarn
Carded Yarn
Rotor Yarn
Slav yarn

Yarn is also labeled by their thickness. The unit of this is count. The count number of yarn will increase according to the reduce of yarn thickness. Yarn price also increase according to increased of count number. 40 count yarns are thinner than the 36 count yarn. Some common yarn count:

20 count
22 count
24 count
26 count
28 count
30 count
32 count
34 count
36 count
40 count

Normally we used these yarn count for knit fabrics.

Few days ago I visited a spinning factory to let it know that, how the yarn is producing from cotton. This spinning factory only produced 100% cotton carded yarn. Here, I will describe you the yarn producing process step by step with image and video. Thanks!

Please find below a flow chart for 100% cotton carded yarn.

Ø 1st Step: For producing the yarn at first we need to setup a spinning factory. The production capacity of this spinning factory will be depends on our requirement.

Ø 2nd Step: Cotton purchasing by import or from local market. Then store the cotton separately based on its origin, quality & fiber length etc.

Ø 3rd Step: Blow room section – In this section the cotton goes under several treatment or operations. Such as- Fiber opening, Cleaning, Dust Removal, Blending etc.

Ø 4th Step: Carding section – After end of the blow room process the cotton comes in the carding section. The cotton comes automatically in these carding machines by pipe. A spinning factory has several carding machine. Two proverbs of the experts - "the carding is the heart of the spinning mill" and "well carded is half spun"

Ø 5th Step: 1st Drawing – From the carding machine we got Sliver. The breaker drawing (1st drawing) machine makes even the sliver by doubling process.

Ø 6th Step: 2nd Drawing – After finished the process of 1st drawing by the finisher drawing (2nd drawing) machine we make the sliver more even (as much as possible.)
