Quality Management in Spinning Mills

Quality Management:                              Quality management consists of four parts, such as; quality planning, quality control, quality assurance and quality improvement. Quality planning deals with planning the activities to meet the customer needs, whereas quality control deals with monitoring the activities using different control points and checks to ensure bad quality does not go to the customer. Quality assurance is focused on establishing systems and procedures to ensure that quality is achieved all the time. In this article I will explain all four parts of quality management. Quality Planning:            Quality planning is the process of planning the production activities in order to achieve the goals of meeting the customer requirements in time, within the available resources.           In textiles, the ultimate consumers and the me...

Working Process of Draw Frame Machine

Draw Frame               Draw frame is a machine for combining and drawing slivers of a textile fiber (as of hemp for rope manufacture or cotton for spinning). Drawing is the operation by which slivers are blended, doubled and leveled. In short staple spinning the term is only applied to the process at a draw frame. In drawing slivers are elongated when passing through a group of pair rollers, each pair is moving faster than previous one. Actions Involved in Draw Frame Drafting: It is the process of increasing length per unit weight of sliver. It is mainly due to peripheral speed of the rollers. Doubling: The process of combing two or more carded sliver into a single form is called doubling. In draw frame m/c generally six slivers are fed to convert into one i.e. six doubling. Drawing: In the cotton industry the term is applied exclusively to processing on the draw frame, where the operation is one of doubling and drafting. Drawing= Drafting + Dou...

Drawing or Draw Frame | Objects of drawing | Importance or Necessity of Draw frame

Draw Frame                  Drawing is the operation by which slivers are blended, doubled and leveled. In short staple spinning the term is only applied to the process at a draw frame. In drawing slivers are elongated when passing through a group of pair rollers, each pair is moving faster than previous one. This permits combing, drawing and elongating of several slivers to make them strong and uniform.In most modern worsted drawing sets there are 3 passages of pin drafting and roving process. Fig: Rieter draw frame Objects of drawing To straighten the crimped, curled and hooked fibers. To make the fiber parallel to their neighbors. To improve uniformity of fibers by drafting and doubling. To reduce weight per length unit of sliver. To remove dust from slivers. To blend raw material of same hank perfectly. Importance or Necessity of draw frame in yarn production To parallelization of fiber and blending the carded sliver,...

Factors Affecting Productivity in a Spinning Mill | Factors for Production in Textile Spinning Mill

Factors for Production in Spinning Mill In every factory, production efficiency defends on some factors or parameters. As like other factories, the production of the Spinning mill depends on some factors. The factors which influence the production of the spinning mill are mentioned below: Fig: Spinning mill (ring frame section) 1. Raw material 2. Labour 3. Machinery Ends down Doffs Creeling Bobbin size 4. Maintenance 5. Energy issue 1. Raw Material Raw material has an important impact on yarn quality and production. Let’s see how it affects on yarn production? There are many parameters through which we can easily assess the properties of cotton; first one is the fiber length which is the most important characteristic of cotton and is measured in terms of staple length, span length and effective length. If fibers have good staple length it results in the form of high production because less twist per inch is required to give enough strength. The second one is the short...

Quality Control in Spinning Mill

What is Quality in yarn? • Ask For specifications • Ask End use of the yarn • Ask Ultimate use of the products  made of yarn • Understand  Implied needs of the  customer/Consumer  Types of Quality • Right quality • Optimum quality • Excess quality • Costly quality • Economical quality • Competitive quality • Consistent quality Quality Contributors(Visible) • Raw material • Machinery • People • Working conditions • House keeping • Process • Management Quality contributors(Invisible) • Systems • Responsibilities • Training • Knowledge • Updates • Follow up Quality contributors   (Carriers/factored items) • Sliver cans, Its castors, Its springs • Spools • Roving bobbins • Ring tubes • Paper cones • Packing materials • Material handling equipments. • Material keeping shelves, Crates • Yarn carrying trucks, Containers Critical Activities to ensure  Quality • Audit Maintenance schedules  adherence • Audi...
