In these models, the loop length is defined as the function of parameters other than loop width (1/W) and height (1/C), and yarn thickness. The loop length of the open knitted structure (ℓ) defined by Peirce [12] is:(2) L = 2 A + B + 5.94 d where A = loop width, B = loop height, d = yarn thickness.

How do you find the loop length of a knitted fabric?

Loop length is found by dividing the stretched yarn length by the number of loops in one course and expressed as follows: Loop length ( ) = uncrimped yarn length in one course/number of loops in one course ( ) [3].

How do you measure the width of a knitted fabric?

Needle Calculation Formula: Single bed flat knitting m/c’s needle = width× gauge. GSM = {WPI× CPI × (39.37)2×stitch length (mm) ×Tex /1000× 1000} g/m2. Stitch density = (WPI × CPI) inch-2 = (WPC ×CPC) cm-2. No of sinker = No of needle.

How do you calculate wales per inch?

Ans.: TF = 14.7 = √tex/loop length cm Loop length inches = l = 0.146 Wales/inch = KW / l = 4.29/0.146 = 29.38 Machine gauge for yarn of 20s Ne = 20 Open width of tube of diameter 26″= 81.68″ Number of wale lines in fabric = Number of needles in machine = 29.38 x 81.68″ = 2400 = π x machine diameter x machine gauge

What is tightness factor in knitting?

11 2.6 Tightness factor Fabric tightness is the relative looseness or tightness of knitted fabrics,so as it implies looseness and tightness of a knitted fabrics, the only things that can varies this is the loop length which is also known as stitch length.

How do you calculate loop length?

In these models, the loop length is defined as the function of parameters other than loop width (1/W) and height (1/C), and yarn thickness. The loop length of the open knitted structure (ℓ) defined by Peirce [12] is: (2) L = 2 A + B + 5.94 d where A = loop width, B = loop height, d = yarn thickness.

What is stitch length?

What does stitch length mean? It’s a distance between two consecutive punches of a needle in one step sewn by a sewing machine. Or maybe another way of defining it – it’s the distance the fabric advances between two punches of the needle. Most modern sewing machines indicate stitch length in millimeters.

What is considered the width of fabric?

The width of the fabric or WOF refers to the distance between the outermost warp threads. The usable width of your fabric is the measurement between the warp thread on the left edge to the warp thread on the right edge, minus any selvage.

What are the different widths of fabric?

3 DIFFERENT TYPES OF WIDTHS

• Widths of Fabric— Fabric is woven in various widths, some of the most common are 54”, 72” and 118” wide.
• Fabric Width— The amount of fabric widths in a treatment is determined by the width of fabric, rod width and fullness.

How is GSM calculated?

How to Calculate Fabric GSM by GSM Cutter:

1. Cut the fabric with the GSM cutter (gram per square inch).
2. Weight the fabric with the electric balance.
3. The cut sample is 100 sq. cm. The weight of the cut sample is multiplied by 100.
4. The result is the GSM of that particular fabric.

How do you calculate dye capacity?

So, the capacity of a package dyeing machine can be estimated in below formula. Average Production Capacity = (Batch Loading Capacity * Machine Efficiency * 24 / 10) kg/day. If an 85% efficient machine has capability of dyeing 500 kg yarn in each batch, average production will be 1020 kg/day.

What is GSM in knitted fabric?

GSM means grams per square meter. For example, the lighter the fabric, the lower its bending rigidity. GSM is an important parameter of knitted fabrics which is very essential for a textile engineer for understanding and production of fabric.

What is stitch density in knitting?

Stitch density is the number of stitches per unit area, obtained by multiplying the number of courses per inch (25 mm) by the number of wales per inch (25 mm). Like woven fabrics, a knit fabric also has a technical face and a technical back and can differ in appearance on each side.

How do I test my knitting gauge?

The ratio between width of the fabric of 28 and 24 gauge machine is = 175/150 = 1.166667 and the ratio between the ratio between the number of wale of 28 and 24 gauge machine is = 2638/2262 = 1.1662246. The both ratio are almost same. So the width of the fabric largely depends on the machine gauge.
