How do you check a CSP of yarn?

C.S.P is the product of English count and strength of yarn in pound. i.e. C.S.P = Strength of yarn in pound x Count in English system.

How do you measure yarn strength?

Observations & Calculations:

  1. English Count of Yarn = 20.
  2. Tex = 590.5/Yarn Count = 590.5/20 = 29.525.
  3. Pre-tension given to yarn = 29.525 x 0.5 = 14.7625.
  4. Machine Gauge Length = 500 mm.
  5. Speed = 5000 mm.
  6. 0.70 = Substance Utilization (Yarn Area Utilization)/100 = 70/100.
  7. Tenacity = no.

How can you tell the quality of yarn?

The fineness of yarn is expressed by count, or linear density. In the Metric count, Nm, it is determined by the number of one kilometer yarn weighing in One Kilogram. The Tex or Denier system takes the weight in grams of either 1 or 9 kilometers of yarn.

What is the meaning of CSP in textile?

Count Strength Product (CSP)

What is CWC in yarn?

Combed Cotton Yarn in Kanpur.

What is Lea strength tester?

Lea Strength Tester, also named Electronic Strength Tester or Lea yarn Strength tester. Lea strength tester is suitable for testing tensile strength and elongation of yarns, fabrics and other materials, It is based on checking principle of constant rate of elongation (CRE).

How do you calculate yarn count in GSM?

‘GSM’ means ‘Gram per square meter’ that is the weight of fabric in gram per one square meter.

Relation Among Yarn Count, Machine Gauge & Fabric GSM:

What is yarn analysis?

Textile has two processes, mainly divided into spinning and weaving. … Therefore, when analyzing the quality of textiles, it is necessary to make a comprehensive and systematic analysis of the structural factors on the yarns used in the textiles such as the type, the shrinkage rate, fineness, twist direction and so on.

How do you find the tensile strength of a yarn?

Using the principle of constant loading rate, the tensile strength of Lee can be determined.

  1. Constant tensile rate (CRE) …
  2. Determination of tensile strength of yarn. …
  3. Product strength score or CLSP. …
  4. CLSP (product strength Lee score) = score (Nec) * Lee strength (in pounds)
  5. Tensile strength by monolayer method.

How is yarn IPI calculated?

The imperfection index (IPI) is the sum of yarn thin places/ km (-50%), thick places/km (+50%) and neps/km (+200%) per kilometer of tested yarn for ring spun yarn [2, 59] .

What is single yarn strength?

Tensile testing of yarns is commonly done in accordance with ISO 2062 and ASTM D2256. These tests are used to determine the breaking force, elongation, and toughness properties of the yarn.

What is yarn RKM?

RKM is abbreviation of Resistance per kilometer. It is an important yarn quality parameter without measurement units. It is calculated from the data of single yarn strength tests performed on manual or automatic single yarn testing installations, for example Uster Tensorapid 3 or Tensojet.
