Ring spinning | Production flow chart of ring-spun cotton & Wool yarn?

Ring spinning is currently the most widely used yarn production method. Initially developed in America in the 1830s, its popularity has survived the emergence of much faster spinning technologies. In addition to the superior yarn quality, ring spinning is extremely versatile. It is capable of producing yarns with wide ranges of linear density and twist from a great variety of fibre materials. It is also used for doubling and twisting multifold and cabled yarns.

Fibre materials must be properly prepared before they can be used on the ring spinning machine. The preparation processes are dependent on the fibre material. Figures 3.1 and 3.2 illustrate the typical process routes for cotton and wool. The ultimate objectives of the many preparation processes are to produce a feed material for the final spinning process that is clean, even, homogeneous and free from fibre entanglement. The fibres must also be in the preferred orientation.

ISO, Classification, guideline and principles of ISO

ISO: 

ISO means ‘International Organization for Standardization’ This standard is a guideline for companies to make their organization capable of designing and producing goods/ products of higher quality acceptable to buyers. ISO standards are guidelines which compel the manufacturers to put into effect quality assurance system to work at all stages of manufacturers and service so that only quality goods and services are produced.

Classification, guideline and principles of ISO

a.     ISO 9001:  This standard is applicable for companies which are involved from designing to manufacturing of goods. This is the most comprehensive method.

b.     ISO 9002: This standard is applicable for companies which manufacture goods with buyers or other specification. This is applicable for export oriented garments industry.

Flow chart of Textile Manufacturing Process

Textile Manufacturing Process is done some regular processes. Each process of textile manufacturing is maintained with a per-defined sequences and the textile engineers usually follow the flow chart step by step to produce the better textile products according to buyers requirement. Usually, the whole textile manufacturing process is divided by four sector. These are-

• Spinning or Yarn Manufacturing 
• Fabric Manufacturing  (weaving or knitting)
• Dyeing, Printing & Finishing
• Garments Manufacturing or Clothing.
