Project introduction
Title:
The effect of raw material on yarn quality and its yield percentage.
BRIEF INTRODUCTION: The Raw material through from which we made cotton yarn is called cotton. In spinning mill yarn is final product we achieve required quality of yarn after passing trough various process.
As yarn is produced for preparation of fabric which is basic need of human being. So with the development civilization best quality yarn is demanded now a days which mainly depend on yarn quality. There are different quality parameters of material and by applying these we decide what the grade of our yarn?
In our project we have correlated the standard characteristics of cotton with mill cotton standard and then we have compared the standard yarn parameters with mill yarn standards. We have studied each and every property of cotton which they buy from different areas.
Different area cotton has different properties with respect to its length, fineness, strength, trash and color. We compare the yarn produced with the material used in mill with yarn standard parameters and observe the difference in quality and yield percent

RAW MATERIAL The cotton variety used IS MNH-93.It is obtained from different stations such as Hasalpur, Bahawalpur, Lodhara, Khanpur, Melsi, Burewala, Rahim Yar Khan, Ahmad Pur, Multan, Kabirwala. In MTM Finance Officers select the cotton variety. Some samples are tested physically and samples are sent to laboratory for testing as well. They started to purchase cotton from September and their target is to purchase about 40,000 bales. Purchasing continues often from September to March. Cotton is selected on the bases of following parameters.
Staple Length Micronair Trash Moisture Dead cotton Strength Contamination Colour grade Stiffness Honey dew U% of fibres
Acceptable values of following: Staple Length = 1.06 - 1.07 Micronair value = 4.5 - 5 Trash = 8.5% Moisture = up to 9% Dead cotton = 0 Strength = 85 - 90 Contamination = as minimum as possible

IMPORTANCE OF MIXINGNow-a-days mixing of raw cotton before blow room action is of entire need for the quality of yarn and fabric. If the cotton is not mixed properly then due-to different characteristics of different cotton shading will occur in the fabric.
SYSTEM OF MIXING There are 3 ways of mixing
1. Blow room mixing 2. Lap to lap mixing 3. Sliver to sliver mixing
TYPES OF MIXING The following types or mixing are used now a days
a) Stack mixing b) Hopper blending c) Continues blending d) Batch blending e) Sliver blending (simple blending, cross can blending)
SPECIAL MIXING PROCESS IN THE MTMSometimes special which is being used In MTM is their special mechanism which is prepared by our "Textile Graduate" the Mill Manager Mr. Munir Ahmad Sahib. He has developed this method of mixing is running successfully.
OBJECTIVES1. To get more check points2. To increase the cleaning efficiency3. Dust removal4. To improve the mixing efficiency
In mixing dept. three auto pluckers are being used one of which is reserved to avoid the stoppage of feed to blow-room. Two of these are always in working condition.Each pluckers feed the material to twelve beaters equipped with small lattices from these lattices the material goes to the main lattice. Cage condenser through suction pipe is to avoid the fluff which also gives advantage of dust removal. Two cages are used; one cage is used for twelve lattices.There are two women working on each side of lattices for contamination picking
COMPONENTS OF EACH UNIT 1. Feed Rollers
There is a pair of fluted rollers which feed the material to the beater.
2. Beater The main component of this unit is a beater which is used for opening of bigger tufts into smaller, tufts. The specifications of beater are as follows:No of rows = 6No of pins/roe = 18Height of pins = 1 ½ inch Thickness of pins at base = 1 ½ inch
DEFLECTING PLATEThere is a deflecting plate below the beater. Its surface is perforated when the material strikes the deflecting plate, the heavy impurities fall down through perforation and material comes on small lattice form which woman picks the contaminations.
Contaminations picked by women are of following types:
1. Coloured cloth 2. Jute 3. Polypropylene 4. Coloured tarn 5. Hairs 6. Yellow cotton 7. Feathers8. Polythene 9. Wrappers10. Straws
SPECIFICATIONSNo of Charnbers = 31 No. of worker/ lattice = 2Length of small feed lattice = 10 ft Width of small feed lattice = 4ft Rpm of beater = 50 r.p.mNo. Of long lattices = 4Width of long lattices = 4 ft
Length of long lattices = 20 ft No. of beating point = 1
STACK MIXING PROCESS It is also celled Sandwich Mixing. It is still preferable. It is pre blow-room treatment. The bales are opened by auto plucker and are taken on to the special mixing region. It is then taken to the mixing room pneumatically and is piled in the form of stack for at least 24 'hours. The moisture content of each bale becomes equal and constant according to atmosphere.
TECHNICAL DATA Cotton 'Variety = MNH 93 1 lot size = 100 bales Issue of bales/day = 110 bales Blend used = 64 lots Bale gross weight = 168 kg Packing material wt = 1.75 kg Net fibre wt = 166.25 kg

The worker on auto plucker is continuously throwing material from outer periphery of the machine to inner side because at the periphery the supervision is necessary to provide even surface of material. This is also a disadvantage with this machine.
ATMOSPHERIC CONDITIONS Relative, humidity and weather conditions for “Mixing hall” are name outside the hall. No special emphasize is given to control environment.
SPECIAL FEATURE 1. There are metallic separators to remove metallic impurities.2. Due to lattices the jute picking become easy. 3. There are enough no of lattices.
BLOW ROOM
INTRODUCTION
After mixing comes the blow-room line. The approach to extract the foreign material is to convert the bulky mass into small tufts thus convenient situation to extract the wastage the blow room has gained, a very position in the spinning line now a days. Even so that YARN is made in the blow room.
ACTION IN BLOW ROOMThe action of blow-room lines are as given
1. Action of opposing spikes 2. Action of air current 3. Action of breakers4. Action of centrifugal force5. Action of gravity6. Regulation action
OBJECTIVES OF BLOWROOM Following basic function are performed in blow room
1. Opening 2. Cleaning 3. Dust removed 4. Blending and mixing 5. Regulation 6. Lap formation
OPENINGIt is a basic function performed in blow room. We get tuft opening here. A tuft of 0.5 kg (about) is opened to about .0.1 mg in the blow room line.
CLEANINGAfter opening second most important function of BR lines' is cleaning i.e. Removal of foreign matter. New blow room approximately remove 40%-70% of foreign matters.
BLENDING AND MIXING According to quality parameter's mixing is most important parameter. Mixing of various materials can be done in blow room to get satisfactory results for hosiery yarn to avoid shade problem. Flock to flock mixing is done in BR.
DUST REMOVAL In blow room line about 64% of dust can be removed. To increase the dust removal, opening of grid bars should be optimum.
REGULATION ACTION: Regulation of material is very important for accur.ate working of cards. Regulating action is obtained by hopper, swing door, photo cells and distributors.
LAP FORMATIONEven today this is best method of feed even material to card. Now a days shoot feed system is also getting popularity throughout the world.

CARDING SECTIONINTRODUCTION Card is mostly considered as one of the most important m/c in spinning industry. It is also called "the heart of spinning" because it separate the fibres up to single fibre stage without which drafting imperfection cannot be eliminated and in spinning industry yarn is manufactured by drafting so card is considered as the most important machine in spinning industry.

Working : four or eight slivers are fed into the drafting arrangement a positively driven feed roller pair is located above each can to enable the feed to be performed in a contolled manner without false drafting .The slivers running into the drafting arrangement leave it after
a draft of 4.48-11.69 in order to disintegration of the web ,it is condensed in to a sliver by a reducer immediately after drafting operation .The sliver by is then guided though a tube via gear passage in to can .
automatic can changing the modern high performance drawing frames are usually filled with automatic can changers. These reduce the burden on the personnel ,enabling more m/cs to be allocated to one person.

Leveling system : The auto leveler draw frame RSB-D30c is equipped with an electronic leveling system.
All slivers fed to m/c pass through a pair of scanning rollers.one of the two rollers is equipped with a moveable bearing. This roller moves according to the variation in the sliver cross –section .
These movement are transformed into voltage by a signal converter and forwarded to an electronic leveling processor D90 .
The leveling process D90 furnishes the accurate target speed to the servo motor M90 and servo leveler G90 – based on :
1) Electric signals supplied by scanning roller and sliver feed .
2) Draw frame delivery speed The servo drive generates the controls speed for the planetary gearing (differential)This controlled speed pf planetary gearing drivers the entry of the drafting system back roll and middle roll.This way the required changes in draft are accomplished and the weigth varia tion of incoming sliver are leveled . The speed of delivery roll remains constant depending upon the selected delivery speed and ensures production rates which can be calculated exactly .
Lap Former Comber Lap Essentials 1) Comber lap should be prepared in such a way that sufficient no
.of doubling be used .2) It should be sufficicently drafted 3) Regular lap along its linear density should be prepared 4) These should be no phasing tendency in the lap step drafting
discouraged5) Even no of macjine should be used between comber and card 6) Hook should be first fed to comber7) The lap should be homogenous with no any identity of the

The combing machine
Introduction:
Comber was developed due to wishes of quality mass now a days is the age of production .particularly hosiery yarn production .The combing has achieved an important place in the spinning line for fine counts.Comber improves the following parameters of the yarn by removing the short fibers and the neps.
1) strength2) Cleanliness3) Smoothness4) Visual appearance
In addition to the above ,yarn made of combed cotton needs a less twist than a carded yarn and obviously more production.Comber is unique is its operation .it is a combination of complex mechanicl expectancy .
Types of comber These are four types of comber:
Rectilinear comber (with stationary or oscillating nipper )
Circular comber (English worsted process)
Rotary comber
Hacking machine
Degree of combing :
1. Scratch combing Noil % removed in scratch combing is 6 – 8 % . It is done for imported cotton
2 . Ordinary combing
Noil % removed in ordinary combing is 12 – 16 %.it is used for Pakistani and imported cotton
3 .super combing : Noil % removed in super combing is 18 – 20 , ensure that no fiber is present in combed sliver the manufacturing of special yarn.
4. double combing :
It is a two stage process
. in first stage 60 % of the total noil is removed .
. And remaining 40 % is removed in the second stage

Impact of raw cotton on yarn
Quality of yarn in
Masood textile Mills
1) On 02/05/2010 MTM issued cotton having moisture content 9 .The cotton was processed in three days and on 05/05/2010 yarn U % was 10.97.It was increased from 10.1.which was processed on 03/05/2010.It shows negative impact on yarn U% .
2) On 13/05/2010 MTM issued cotton having moisture content 7.14 .The cotton was processed in three days and on16/05/2010 yarn U % was 9.88.It was reduced from 10.5.which was processed on 13/05/2010. It shows positive impact on yarn U% .
.
EFFECT OF MOISTURE:
Moisture in atmosphere has a great impact on the physical properties of textile fibres and yarns..Relative humidity and temperature will decide the amount of moisture in the atmosphere. High relative humidity in different departments of spinning is not desirable. It will result in major problems. But on the other hand, a high degree of moisture improves the physical properties of yarn. Moreover it helps the yarn to attain the standard moisture regain value of the fiber. Yarns sold with lower moisture content than the standard value will result in monetary loss. If the moisture perecentage in the raw material is more than the fiber get stick with one another
if we use moisture with less perecentage then fiber lost their strength and fiber become weak.Therefore the aim of conditioning is to provide an economical device for supplying the necessary moisture in a short time, in order to achieve a lasting improvement in quality.
4)On 07/05/2010 MTM issued cotton having Trash percentage 6.02 .The cotton was processed in three days and on 11/05/2010 yarn U % was 9.91.it was reduced from 10.45 which was processed on 07/05/2010. It shows positive impact on yarn U% . .5)On 02/06/2010 MTM issued cotton having Trash percentage 7.22 .The cotton was processed in three days and on 06/06/2010 yarn U % was 10.27 .it was increased from 9.87 which was processed on 03/06/2010.It shows negative impact on yarn U% .
EFFECT OF TRASH: Trash, often referred to as non-lint, commonly comprises fragments of leaves, bark and grass, as well as particles of sand and dust. The levels of such contaminants are determined by growing, harvesting and ginning
conditions. Plastic materials also represent a serious source of contamination. Trash content is directly and indirectly related to processing waste, the removal of trash being associated with fibre breakage and the removal of fibres as waste, as well as nep formation. These in turn can considerably affect spinning performance, particularly rotor spinning, and yarn quality. if the percentage of trash is more than we have to do more opening and cleaning which results more neps. Short fibers and impurities .If the percentage is low then the yarn quality is increased
6)On 03/06/2010 MTM issued cotton having floating fiber 16.01.The cotton was processed in three days and on 07/06/2010 yarn U % was 9.87.It was reduced from 10.22 .which was processed on 05/06/2010.It shows positive impact on yarn U% . .7)On 01/10/2010 MTM issued cotton having floating fiber 21.41.The cotton was processed in three days and on 04/10/2010 yarn U % was 10.26.It was increased from 10.1which was processed on 02/05/2010.It shows negative impact on yarn U% .
Effect of floating fibers: The negative effects of the presence of a high proportion of short fibres are well known. A high percentage of short fibres are usually associated with,
- Increased yarn irregularity and ends down which reduce quality and increase processing costs - Increased number of neps and slubs which is detrimental to the yarn appearance - Higher fly liberation and machine contamination in spinning, weaving and knitting operations. - Higher wastage in combing and other operat
8) On 07/05/2010 MTM issued cotton having Staple length1.054 .The cotton was processed in three days and on 11/05/2010 yarn U % was 9.91.It was reduced from 10.11 which was processed on 09/05/2010.It shows positive impact on yarn U% . .
9)On 21/05/2010 MTM issued cotton having Staple length 1.048 .The cotton was processed in three days and on 24/05/2010 yarn U % was10.25.It was increased from 10.11which was processed on 26/05/2010.It shows negative impact on yarn U% .
Effect of staple length: Length, length uniformity and length distribution, including short fibre content, are probably the most important cotton fibre properties, although their importance does depend somewhat on the spinning system used.The staple length affects more on the yarn quality .The longer the staple length the yarn will be stronger and uniform .An increase of 1 mm in fibre length increases yarn strength by some 0.4 cN/tex or more. If the staple length is short .then yarn will be uneven and weak
10)On 03/05/2010 MTM issued cotton having Uniformity ratio 47.9.The cotton was processed in three days and on 07/05/2010 yarn U % was 10.45It was increased from 10.1which was processed on 03/05/2010. It shows negative impact on yarn U%
11)On 03/06/2010 MTM issued cotton having Uniformity ratio 50.19 .The cotton was processed in three days and on 07/06/2010 yarn U % was 9.87 .It was reduced from 10.22 which was processed on 05/06/2010.It shows positive impact on yarn U% . .
Effect of uniformity ratio: Length uniformity or uniformity ratio is determined as “a ratio between the mean length and the upper half mean length of the fibers. If the uniformity ratio of fibers is good then more the yarn will be uniform and if the uniformity ratio is low then it gives less uniform or less even yarn.
