Indirect Yarn Count System

Yarn Count

There is a nice definition of yarn count according to textiles institute of UK, “count is a number of indicating the mass per unit length or length per unit mass of yarn of yarn”

In other word count can be defined as , the numerical values which expresses the fineness or coarseness of yarn. It indicates the relationship between length and weight also.

So, “Yarn count is a number which indicate the mass per unit length or the length per unit mass of the yarn”

Indirect yarn count system or numbering system

Classification of Yarn count

Direct Count

Study my another article about direct yarn numbering (direct count) system

Indirect count (length/weight)

The length of a fixed weight of yarn is measured. The length per unit weight is the yarn indirect count. General features of all indirect count systems are the weight of yarn is fixed and the length of yarn varies according to it’s fitness.

Points should remember during indirect count

  1. In indirect count system weight is fixed.
  2. Higher the yarn number finer the yarn and
  3. Lower yarn number coarser the yarn.

The following formula is used to calculate the indirect yarn count

Formula of Indirect Count

Here,

N = Yarn count or numbering system

W= Weight of the sample

L = Length of the sample

l = Unit of length of the sample

w =The unit of weight

Some indirect yarn count system

 English count system, Ne              : No of 840yd lengths per pound

Metric count, Nm                               : No. of kilometers per kilograms

Woolen count (YSW)                        : No. of 256 yd lengths per pound (lb)

Woolen count (Dewsbury)              : No. of yd lengths per oz

Worsted count, NeK                         : No. of 560 yd lengths per pound

Linen count, NeL                              : No. of 300 yd lengths per pound

Discussion

English Count

English count indicates how many hanks of 840 yards length weighs one pound.

That means, if count 40 Ne, then it means 40 hanks (bundle) of 840 yards will give 1 pound weigh.

(Note: So, for gaining 1 pound weigh, 840 yards long how many yarn bundle we will in need, this require number of bundle is the English count of this yarn.)

Here count 40 Ne means, 40 bundle of yarn with 840 yards length will be required to get 1 pound weigh.

So, hopefully it was helpful for you to understand English count properly. If you like it do not forget to put down your valuable comments and share on facebook

Yarn Count

Direct Yarn Numbering (Yarn Count) System

Count is a numerical value which is used to express the fineness or coarseness of the yarn. yarn count also indicates the relationship between length and weight of the yarn. So, as definition of yarn count we also can say yarn count has been introduced as a certain ratio of length to weight or weight to length.

Types of yarn count

There two types of yarn count system. They are as follows.

  1. Direct Count System
  2. Indirect Count System
yarn count

Textile Yarn

Direct Count System

Direct count is determined by the weight of a fixed length of yarn. The weight per unit length is the count (direct count). The common features of all direct yarn count systems are the length of yarn is fixed and the weight of yarn varies according to its fineness.

We should remember in direct yarn count system

  • In direct count system Length is fixed.
  • Higher the yarn number coarser the yarn and
  • Lower yarn number finer the yarn.

The following formula is used to calculate the direct yarn count

N = (W × l)/L

Here,

N = Yarn count or numbering system

W = Weight of the sample

L = Length of the sample

l = Unit of length of the sample.

Some direct yarn count system

  1. Tex system
  2. Denier system
  3. Decitex
  4. Militex
  5. Kilotex
  6. Jute count

Brief definition of the above direct count system

As I have given the definition above, now here I am going to present brief definition of above direct count system.

Tex system    : Number of grams per 1000 meters.

Denier            : Number of grams per 9000 meters.

Decitex           : Number of grams per 10,000 meters

Militex            : Number of milligrams per 1000 meters

Kilotex            : Number of kilograms per 1000 meters

Jute count     : No. of pound (lb) per 14,400 yards

Indirect Count System: (Will discuss in my next article. Remain with us.)

Discussion

Example :

Now I am going to disscuss about direct yarn count system with an example so that we can understand it more clearly.

  • Suppose 35 Tex,

What 35 Tex defines?

35 Tex means 1000 meters of yarn weigh 35 gram. If 1000 meter long yarn gives 35 gram weight then it is called 35 Tex. Hope it is clear now.

Others direct yarn count system also define so,

Wish it was helpful. Now I am going to ask you some question about direct count system. Try to solve these questions by yourself. Or, you can also give your answer as comment below the post. I will discuss about these following question in my upcoming post. If you have any other question never hesitate to ask me.

Questions :

  1. 20 Tex defines…………………
  2. 35 Denier defines………………..
  3. 35 Tex defines………………………
  4. 10 Decitex define…………………….
  5. 5 Kilotex defines………………………..
  6. 10 Jute count defines……………………..

Combed Yarn

Combed yarn is a yarn which is produced by combing process. This yarn is finer than carded yarn. Generally combing produced 60 count or more than 60 count yarn. But sometimes 32 counts or 40 count yarn also produced by combing process. It is high quality yarn and it is more expensive compared with carded yarn because its combining process is time intensive.

Combed Yarn

Functional steps of Combed yarn manufacturing process

Functional steps related with this manufacturing process are blow room, carding, pre-comb drawing frame, lap frame, combing, post comb drawing frame, simplex, and finally ring frame.

Functional steps of Combed yarn manufacturing process

Combed Yarn Manufacturing Process

Features of combed yarn

There are several features of combed yarn can be identified these are given below shortly:

  • Higher count yarn
  • More finer than carded yarn
  • Produced excluding short fibre
  • Regular yarn
  • High quality yarn
  • Uniform yarn
  • Smooth yarn
  • Good water absorbency
  • Less hairy
  • Normally naps free
  • Costly Production
  • High price
  • Higher breaking strength

Calculation of Yarn English Count

Calculation of Yarn English Count

English Count

English count indicates how many hanks of 840 yards length weigh one pound. That means if count 40 Ne Than it means 40 hanks(bundle) of 840 yards will give 1 pound weight.

 (Note: So, for gaining 1 pound weight, 840 yards long how many yarn bundle we will in need, this require a number of bundles is the English count of this yarn.)

Calculation of yarn English count

Different Count Yarn

  • Why calculation: Most of us are fear from count calculation. But we should have a common sense of calculation to be good textile personnel.

Let’s try to solve the following problem of English count

 

On one cone there are 9800 m yarns which weigh 490 gm. What is the English count of this yarn?

We know,

For Ne(English count),

problem of English count

Calculation of Yarn English Count

 So, Here count 12 Ne means, 12 bundles of yarn with 840 yards length will be required to get 1 pound weight.

So, wish it was helpful for you to understand English count properly. If you like it doesn’t forget to put down your valuable comments and share on facebook

Classification of Yarn

Classification of Yarn

The yarn is a continuous strand which is made by natural or synthetic fiber or material twisted or laid together that can be made into a textile fabric. So, a continuous twisted strand of natural or synthetic fibers used in weaving or knitting to produce fabric. If you are involved in the apparel industry then you must know the classification of yarn.

Yarn Classification

  • Classification according to their structure

The yarn may be divided into three types according to their structure. They are as follows:

1. Single yarn/staple fiber yarn / spun yarn

By mechanically assembly or twisting of staple fibers together spun yarns are made. Ring spinning, Rotor spinning, wrap spinning, Air-jet spinning etc. machines are used to produce this single yarn or spun yarn.

2. Ply yarn

For normal textile and clothing producing single yarn is used. But ply yarns are often needed to obtain special yarn features such as:

  • To ensure high strength
  • For gaining special properties.

**A ply yarn is sometimes called folded yarn also. It is produced by twisting two or more single yarn together.

**Another is cabled yarn which is produced by twisting two or more ply or folded yarn.

The direction of twisting of yarn to make ply yarn is defined as S or Z twist. Generally, the folding twist is in the opposite direction to that of the single yarn.

classification of yarn

Single Yarn & Ply Yarn

3. Filament yarn

The yarn which is made from one or more continuous strands is called filament yarn. In filament yarn, each component filament which is used to make this filament yarn runs the whole length of the yarn.

Filament yarn can be classified in following ways

classification of yarn

Classification of Filament Yarn

Mono Filament yarn: Those filament yarns which are made from one filament is called mono filament yarn.

 Multi filament yarn: Those filament yarns which are made from more filaments is called multi filament yarn.

Texturing is the main method used to produce the bulked filament yarn. Silk is the only major natural filament.

classification of yarn

Filament Yarn

Classification of yarn according to their use

The yarn may be divided into two categories according to their use. They are as follows.

1. Weaving yarn

Yarns which are made for weaving purpose should have following properties:

  • Yarn of lengthwise direction should be stronger.
  • They should have a tighter twist.
  • They should be smoother
  • They should more even than filling yarns.
  • Highly twisted crepe yarns are usually found used as filling yarn.

Note: filling yarn means the yarn which is used in the crosswise direction of cloth.

Ready Warp Yarn for Weaving

2. Knitting Yarn

Knitting yarns are twisted more slackly than weaving yarns. Knitting yarn can be of two types. I.e.

  • Hand knitting yarn
  • Machine knitting yarn
