The operators operate the machine very carefully as if there are no defects in the fabrics. If the number of feeders increases on the circumference of the cylinder, the number of hinges will increase one revolution at a time. Yarn packs are stored here to feed the yarn to the machine 2.VDQScrew: This part is used to control the stitch length and GSM knit.
Generally, a roll of fabric is cut when it reaches the 'specified cut length' in the m/c circular knitting, but the roll can be cut before it reaches the predetermined length if required and the weight is recorded other number, quantity, GSM, Knitter, Shift, Style, Yarn Lot, Roll Quantity, Machine Rolls, m/c no. Defects found and the points assigned to them are recorded in the daily body and rib inspection report and in the daily collar and cuff inspection report. Vertical line: Defective needle, dirt in the needle slots, needle to be lost or too tight in the holes, needles not lubricated enough.
Oil Lines: Fibers and lint collected on needle tips, which remain soaked in oil. Needle Lines: Bent latches, needle hooks and needle tails Tight needles in grooves Incorrect needle selection (Incorrect needle alignment, set on cylinder or dial).

Bleaching is another important step used to reduce the natural color of the raw materials. Check whether the dust circulation is normal and then close the gate door (check the reel speed again). Add humectant, sequestering agent, sodium hydroxide and hydrogen peroxide and run for 20 minutes at 1100 C for single yarn and 1150 C for double yarn.
The shade of the textile material depends on the dye percentage used for dyeing.

- Description of Different Finishing and Washing Machine
Aesthetic Finishes: This type of finish changes or modifies the appearance of the fabric or the properties of the handloom/drape fabrics. Durable finishes: Usually last the life of a fabric, effectiveness diminishes after each cleaning, and near the end of the fabric's normal use, the finish is almost completely removed. Open shape fabric finishing line; The cutting machine is used after the hydro-extraction, de-watering and drying machine.
Shearing is a process applied to cut the tubular fabric through the intended Welsh fracture line in the longitudinal direction prior to stenter processing. Cutting Line Control: The fabric cutting line is controlled by the cutting machine operator. Bow and Tilt Control: Bow and tilt are controlled on the delivery side of the machine by Manufacturer: Bianka Slitter m/c (Germany).
The main function of the stenter is to stretch the fabric in width and regain the uniform width.

Markings are the layout of pattern pieces for the purpose of cutting the fabric. Much effort is made to arrange patterns in the most economical manner within the constraints of fabric type, width, nap and fabric design. During this process, extra sewing thread and various unnecessary things are removed from the garment. Prepared garments now go through the metal detector for checking. If any metals like broken needle etc. are found, the machine stops and the garments are checked to remove the thing.
Clothes are now ironed at a high temperature which will not cause any damage to the garments. Now the sticker is attached with the garments with heat (1000c-1500c) is applied to fix it. The supplier must ensure that the heat setting is sufficient to adequately seal the bags without overheating the bags and weakening the bags' strength.
To ensure that the comic is sufficiently strong and secure the content inside the normal transportation and distribution process according to the standards. After garment preparation, before packing this shorts inspection is done to remove the defective garments. Defects are identified here and, if possible, the garment is sent back to a respected department to resolve the issues.
For the textile and clothing industry, product quality is calculated in terms of quality and standard of fibers, yarns, material color, design and the final finish of the garments. Critical defects: are those that make the product unsafe or dangerous for the end user or that violate mandatory regulations.
Utility Section
- Boiler
- Generator
- Air Compressor
The air compressor sucks air from the atmosphere, compresses it and supplies it under high pressure to the storage tank. From the storage tank, it can be piped to where the supplied air compressor is needed.
