There are two methods which are followed to prepared the beam for mounting on the loom.
These are:
Warping trying or knotting
Drawing in
Warping trying or knotting
The method has some limitation to used where an exactly same article or quality of fabric is to be made that is already running on the loom before knotting the following points should be consider
The total number of warp ends should be same as that of already running into the loom.
The count of warp yarn and weave design be same.
Drawing in
This method of mounting weavers beam on the loom is adopted when the design and quality differs from the existing one. The yarn as it comes to drawer hook is then drawn through dropper, then through the eye of heald wire. All the warp yarn thus drawn one by one finally pass through the split of the dent of reed is called denting
Equipment Used
For Tying a sized and leased beam with the already running beam in the loom. Following typing of machines are used: Knotex warp typing machine for mono color fabric.
Key Accessories:
Key accessories used for drawing are : Drawer’s hook, Reed knife
Key accessories used for warp tying are: Brush, Leasing band, Stand frame
Safety:
In order to ensure floor and personal safety are instructed to following the safety guideline given bellow:

Check the whether any are crossing
Check whether any empty dropper is left or not
Warp tying process:
The operation procedure for warp tying is enumerated under the following points
The beam is loaded on to a specific loom and mounted on beam bracket. The tying frame is set in the roper position.
The ends of the old beam and the ends of the new beam are accurately brushed and gripped by the frame so that older and new ends makes a upper and lower set of yarn placed in proper tension.
Then warp tying head is mounted over the tying frame
Then machine is started, operator will check the correctness of the knot and start again by switch
Thus knotting will be completed up to the end of set tying upper set of older yarn with lower set of new warp
Thus knotting is completed tying head and frame are removed, the old pieces of knotted yarn is pulled through the frame and thus new warp set is allowed to pass and made reedy for run.

Singeing machine is the process passed out for removing loose hairy fiber protruding from the surface of the cloth there by giving it a clean looking surface. If the fabric is to have a smooth finish than singeing is essential. Singeing and desizing is a dry process used on woven goods that removes the fibers protruding from yarns or fabrics.
Schematic Diagram Singeing Machine and Desizing Machine
These are burned off by passing the fibers over a flame or heated copper plates. Singeing and desizing improves the surface appearance of woven goods and reduces pilling. It is really useful for fabrics that are to be printed or where a smooth finish is desired. Pollutant outputs associated with singeing include relatively small amounts of exhaust gases from the burners.
Objective of Singeing Machine
To remove loose hairy fibers.
To obtain a smooth Surface.
In order to impart a clearly defined & sharp design.
To prepare fabric for next process.
Desizing
The process to remove the size material applied in weaving section and increase the absorbency power of the fabric is called desizing.

Origin: Germany
Machine description with process
Fabric inlet section: Gray fabrics are directly feed into the inlet of singeing machine. Where the fabric is passed over some free roller, guider & expander to ensure open width entry. Here there is a control panel to control fabric speed.
Fabric inlet section
Cleaning unit 1: Through fabric inlet then fabric is passed through cleaning unit which contain a brush as well as provide a vibrating motion for effective cleaning. From this unit dust are collected through duct in which suction is occurred by a high power motor. Big dusts are collected in dustbin and inferior particles are released in environment.
Machine Cleaning unit
Singeing unit: After passing cleaning unit then fabric comes into contact of flame for singeing. Fabric is passed over the water roller & in water roller flame is attacked tangentially or horizontally depending on fabric type & quality required.
Machine Unit
Cleaning unit 2: when singeing is occurred, the fabric contains few flame sparks on its surface & selvedge. Those are removed by cleaning unit & the dusts are passed through water because they contain fire spark. The inferior particles are moved away through duct in environment.
J Box: if fabric is feed as roll form then two j box is required one after inlet & another before cleaning unit. In continuous process j box is required for the continuity of fabric processing without machine stoppage which saves time.
Singeing Machine J Box
Desizing unit: finally the fabric is passed through desizing unit. Its contain desizing liquor. For desizing wetting agent, Enzyme, sequestering agent, acetic acid is required. Temperature is maintained around 80-100’C.
Chemical mixing unit: Beside desizing unit there are two chemical tank one of them is called reserve tank where chemical is mixed & circulated, another is storage tank where agitated chemicals are stored for using in bath. From this chemical entered in bath as required for even immersion.
Chemical mixing unit
Batching unit: After desizing fabric is collected in rolled in batcher in uniform tension. Then the fabric goes for rotation of 10-12 hours. For proper decompose of starch it is essential.
Batching unit
Rotation: After batching the fabric is packed by poly bag. Then it goes for rotation for 8 to 12 hours. In this time water react with starch in presence of enzyme & decomposestarch as water soluble glucose.
Rotation
A typical Recipe for Desizing
Solid dyed fabric desize Recipe-
Wetting agent: Rucolase F.W.K– 7 gm/lt
Enzyme: Rucolase H.C.H – 8 gm/lt
iii. Dearting agent: Rucowet V.L-1g/lt
Sequestering agent: Verolaw N.B.O – 1 gm/lt
Acetic acid – as required to maintain pH
Yarn dyed fabric desize Recipe-
Wetting agent: Rucolase F.W.K – 5 gm/lt
Enzyme: Rucolase H.C.H – 5 gm/lt
Here,
Enzyme: Enzyme can make soluble the sizing chemical in H2O.
Wetting agent: it is used to increase the wettability of textile substrate and dye-stuff in water to easy penetration and obtain smooth paste. i.e. T.R oil.
Sequestering agent: It is used to minimize the impact of hardness of the water. i.e EDTA.
Dearating agent: It is used as antifoaming agent and increase the penetration of wetting agent.
Note: – In woven fabric processing Gas singeing machine is widely used. -The singeing is not applied above 45 count of fabric.
Material and Chemical used
Steam, compressed air, water, natural gas, Desizing agent, wetting agent, sequestering agent and dearating. Sizing Machine also work similar process.
Check list before production
Operator must check the following before starting production of the fabric named bellow:
All cotton colored fabric = Singing & Desizing.
All cotton colored peach finish fabric = Desizing.
But we will have to ensure that every side can absorb equal amount of chemical.
The amount of times which are fabrics take in passing the desizing chamber can be calculate as-
By dissolving test:Here 1’’ grey cloth with square cross section (□) will have to take in a 500ml pot. Then we will have to take the times which the fabric takes to dissolve in this solution.
Clip test: Here a clip is used to measure the times which the fabrics take in desizing chamber. In this process we will have to pass the clip from pressing roller to padder cylinder and have ti calculate the passing time of clip by stop watch.
Problem of Singeing Machine and Desizing Machine
During operation there are several problem occurred such as:
Sometime fire comes out unevenly due to breaking of burner surface. This can make uneven singeing.
Problem in bearing of roller. This is the most common problem.
High temperature in singeing machine section that occurred when even cold water is not flowed. When temperature is so high machine stopped automatically.

Waste Disposal Procedure
The management of AUTO emphasizes on establishing Environment Management System (EMS) inside & outside its factory premises to ensure environmental protection in the process of using raw materials, manufacturing products and discharging wastes. The management is firmly committed to comply all the relative obligations to ensure environment friendly condition in and around the factory.
The company has developed certain systemic procedures for the disposal of its wastes to prevent any environmental pollution and also for the safety of the workers & staff as well as the overall community.
Disposal wastes in AUTO are Empty Drum, Waste Accessories, Waste Metal Items & Waste Glass Items etc. Specific guidelines for the disposal of wastes are mentioned below.
Day to day wastes inside the production system will be kept in the respective area or waste boxes and at the end of each working day all of these wastes will be dispatched outside the factory in a designated safe place.
Empty Drums, Empty Container, Empty Bottle, Waste Plastic etc. we keep in a designated area & then send to the supplier for Recycle. The empty container of Thinner & other chemical container should not be used in the factory and not be given to workers for any other purpose.
At first, we try to repair the wastage metal items & if it is not possible then we keep it temporary in the wastage store & sell to the producer for recycle.
We keep all the accessories Waste items such as Carton, Poly, Gum Tape, offset items, Plastic clip & others Wastage in a designated area & & then send to the supplier for Recycle.
Others Items such as fused tube light & Broken Glass we keep in a designated area & then send to the supplier for Recycle.
During the removal of wastes it will be ensured that no nuisance is created because of the removing process and it does not affect the workers staff and also the tenants in and around.
Store & Administration of HR will maintain records of all waste disposals.
To sell the waste one team of three dept. (1 person – Admin, 1 person – store & 1 person from security dept.) will inventory item wise qty. Finally by a challan it will be out from the factory.
Waste which are not sellable, will be destroy by burning at a designated place.
Accumulated list of wastes & disposal procedures:
Segregated wastes are finally disposed of when they are no longer required. Disposal procedure depends on waste category. Some wastes, such as chemical wastewater requires treatment by ETP (Effluent Treatment Plant) and some require simple disposal procedure such as dumping on landfilling site. On the contrary, some other wastes are reused and recycled. In the following tables, we have mentioned all the wastes and their disposal procedures-
This type waste if thorough here & there then fabric do not melted with the soil from which environment may pollute.
Incoming waste fabric firstly is kept segregate in certain area. One / two times in a months handed over to supplier for recycle.

To achieve the high speed running necessary for ,two steel bead bearings share the load
Machinery and Equipment of a Weaving Loom:
Comber Boards:
The comber boards are designed and built to order. For example the loom depth is matched to the number of sinker rows, the density, the type of weaving loom thread and their link to heald. An optimized drilling pattern improves the functioning of the loom and weaving process. The comber board frame makes it easier to change the fabrics widths.
Single Thread Link:
Two recesses serve to retain it when removing. The link between the heald and the spring is fitted with damping system to reduce vibration.
Springs:
The new sectional aluminum draw-down frame is suitable for all densities. The fixing strips can be selected with 32,16 or 2*8 suspension elements to suit the various densities. A draw down plate with individual harpoon fixing is available for velour and carpet weaving loom.
Lease:
The lease is fed into the weaving loom threads in the required sequence in our works with complete accuracy and great care. This saves time when it comes to inserting the weaving loom and commissioning.
Double Density:
With a double comber board it is possible to use the same weaving loom for two different densities or to switch from single to double fabric width. Switching is a quick and easy operation and does not change the loom leveling.
Blower:
Some machine manufacturer has developed the automatic blowing device to facilitate cleaning of the loom springs. The blower is located behind the return motion frame. The pneumatic blower reduces the accumulation of dust deposits and facilitates manual cleaning. The blower system compact format makes it compatible with many types of weaving looms.
Wrap Threads into the Healds:
The loom can supply with wrap threads, e.g. with texturized yarn PES 167 dtex S/Z cotton yarn Nm 40/2, cotton yarn Nm168/2 and PA 470 dtex. This makes commissioning of new plant much quicker and easier.
Weaving looms maintenance
Preventive Maintenance:
Preventive Maintenance is a predetermined routine activity to ensure on time inspection / checking of facilities to uncover conditions that may lead to production break downs or harmful depreciation.
Corrective Maintenance / Break down Maintenance:

Features of Projectile Loom for Weaving Techniques:
The features of different looms with weaving techniques is stated here-
Projectile receiving units are different looms from the stirring sley whe the sley carries the reed & gripper guides,
The gripper projectile made with fine steel to help for making nice weaving patterns
For the duration of its flight through the shed of the projectile runs in a rake likes steel guides as a result the warp threads are touched neither by the projectile nor weft thread,
Generally the gripper projectile is selected across the warp shed on very high speed where the picking energy derived from the energy stored in a metal torsion bar that is twisted for different looms
All picks are cut off at the picking side near the selvedge after weft insertion for the loom
The color changing machinery is less complicated for making weaving patterns
The weft is marked directly from a large stationary cross wound package.
The reed is not joint as in a shuttle the loom but rocked about its axis by the pair of cam.
The reed & projectile guides are stationary for the duration of pick insertion.
Small shed opening because of the smaller size projectile. [2]

Why quality is important?
Quality sells brand reputation or image (Levis, Nike etc). No quality means no order. No order means no production. Customer’s satisfaction to the products. The products must look good to attach consumer’s attraction. If the product is dirty madder no proper packing consumers will not give it a second look.
How to control quality:
Quality controls or quality assurances must have the knowledge to do the checking. He must have the proper quality assurance package & the Audit from or inspection report. Process of checking from cutting of fabrics to finished package.
Jacquard to be checked for defects (no shading, bowing, slubs, broken picks, hole etc)
In line inspection roving & checking on all sewing operation & document the defects. Take immediate action to correct & fix the defects or problems. Sewing machine has problem causing puckering, skip stitch, needle break so check it. The sewing worker should stop sewing.
Quality control chief should receive the audit report of the quality controller in a timely manner. May be one hour interval to ensure the quality of the operation is under control. If there is quality issue quality controller chief should take the matter to the factory manager for him to follow up with the sewing operators for action & correction line supervision should stay with the sewing operator to ensure that the quality is maintained & no more defects.
Factory manager must connected with inventory department for all the trims, accessories for the production.
Objective of quality control:
Research
Selection of raw material
Process control
Process development
Product testing
