Knitting Production Calculations Quiz

The speed of a circular knitting machine, expressed in revolutions per minute (RPM).

The speed of the fabric produced by the knitting machine, measured in meters per second.

Determining the revolutions per minute (RPM) for a given machine diameter using the circumferential speed.

Typical speed of fabric production from a knitting machine, roughly 1.5 m/s.

The number of times fabric is produced in a specific machine diameter in knitting.

Calculations for production, efficiency, material needs and costing of finished knit goods.

Modern circular knitting machines operating at speeds of 1.6-1.7 m/s in factory conditions and potentially higher (at least 2.0 m/s)under laboratory conditions.

Critical dimension affecting the RPM and therefore the speed and output of a knitting machine.

The speed at which a point on the circumference of a machine moves, measured in meters per second.

The speed of a machine, measured in revolutions per minute.

The amount of fabric produced by a machine in a given time frame, measured in length (meters/yards) or weight (kg).

The highest possible production rate or output of a machine under ideal conditions, without any factors of reduction.

The actual production rate, which is the optimum production multiplied by the machine's efficiency.

The ratio of actual production to optimum production, reflecting how well the machine performs against its potential.

A measure of the thickness or fineness of yarn, often described by the number of yarns needed to equal a standard weight.

Calculates fabric production in kilograms per day, considering machine speed, fabric density, and width. It assumes 100% efficiency.

Calculates fabric production in yards per hour, considering machine speed, and courses per inch. It assumes 100% efficiency.

Calculates fabric weight per linear yard based on needle density, stitch length, courses per inch, and yarn count.

Calculates fabric weight per square yard using weight per linear yard and fabric width.

Calculates GSM (Grams per square meter) based on stitch density, loop length, and yarn count.

A value representing the relationship between yarn diameter, stitch length, and count (Tex). Impacts fabric structure and properties like drape and weight.

The distance between two adjacent stitches in the knit fabric, measured in millimeters.

The thickness of the yarn used for knitting, measured in millimeters or 'd' (for direct system) or 'd∞' (for indirect system).

The type of knit construction, affects Ks value and fabric properties. Examples: single jersey, rib, pique, interlock.

A measure of yarn fineness, representing the weight of yarn per unit length.

A method for calculating yarn diameter, using a formula with 'Tex' and a constant.

A method for calculating yarn diameter, using a formula with 'Ne' and 'inch'.

A different measure of yarn fineness, representing the number of yarn lengths per unit weight.

The thickness of the knit fabric, determined by yarn diameter and knit structure.

The number of stitches per unit area, calculated by multiplying courses per cm and wales per cm. Influences fabric drape and handle.

The speed of a circular knitting machine can be expressed in three ways: revolutions per minute (RPM), circumferential speed in meters per second, or as a 'speed factor' which combines RPM and machine diameter.

The speed factor is a calculation combining machine RPM and diameter, expressed in inches, that determines the circumferential speed of the fabric. It's a constant for machines of the same model.

The speed of the fabric produced by the knitting machine, measured in meters per second. It is typically constant for a given knitting machine model despite variations in machine diameter.

The number of feeds in circular knitting refers to the number of times fabric is produced for a specific cylinder diameter. This can be expressed as a total number or as feeds per inch of cylinder diameter.

Production calculations in the knitting industry combine various factors like machine speed, number of feeds, fabric density, and yarn count to determine the amount of fabric produced and the overall efficiency of the knitting process.

Modern high-speed circular knitting machines typically operate at speeds of 1.6 to 1.7 m/sec in factory conditions. In controlled laboratory settings, speeds of 2.0 m/sec can be achieved.

Accurate production calculations are crucial for determining the competitive selling price of finished knit goods. They help optimize yarn usage, equipment needs, and overall manufacturing cost.

Key factors in knitting production calculations include machine speed, number of feeds, stitch density, stitch length, yarn count, fabric density, and machine efficiency.

Calculates fabric weight per linear yard based on needle density, stitch length, courses per inch, and yarn count.

The speed of a knitting machine expressed in revolutions per minute (RPM).
