What is the primary purpose of applying high squeezing pressure in the size box?

To ensure adequate pre-wetting and avoid dilution of size liquor

What is the benefit of using pre-wetting in the size box?

It improves the surface adhesion of the size to the yarn and reduces the size add-on by 30-50%

What is the function of the immersion roller in the size box?

To dip the yarn sheets into the size liquor

What is the effect of pre-wetting on yarn strength?

It increases the yarn strength by 15-20%

What is the purpose of using multiple size boxes?

To accommodate different size materials, warp quality and density

What is the function of the squeeze rollers in the size box?

To squeeze off excess size solution

What is the total number of ends in a reed plan with 36 dents per inch and 2 ends per dent?

72

What is the primary function of the reed in a loom?

To perform the primary motion of beating-up

If the reed count is 72 Stockport, what is the average warp thread density in a reed plan with 24 total ends and 16 total dents?

54 inch

What is the Stockport reed count required to achieve 56 ends per inch with a reed plan of 2 ends per dent?

28

What is the term for the gap between two consecutive wires of a reed?

Dent

If the reed count is 30 dents per inch, what is the average warp thread density in a reed plan with 18 total ends and 13 total dents?

41.5 inch

How is the count of the reed defined in the Stockport reed counting system?

Number of dents per two inches of the reed

What is the purpose of the reed in controlling the warp thread density?

To maintain the required warp thread density

What is the relationship between the Stockport reed count and the number of ends per inch in a reed plan?

The Stockport reed count is directly proportional to the number of ends per inch.

What is the main factor that determines the count of the reed to be used?

Warp thread density required in the fabric

What is the purpose of calculating the average warp thread density in a reed plan?

To determine the density of the fabric.

What is the purpose of the reed in keeping the warp yarns straight and parallel to each other?

To ensure uniform tension

What is the main purpose of the drawing-in draft?

To determine the number of heald frames required for a particular weave design

What determines the number of columns in the lifting order?

The number of heald frames shown by the drawing-in draft

What is the term used to describe the number of ends passing through each dent of the reed?

Reed plan

What is the relationship between the number of rows in the lifting order and the number of rows in the weave design?

The number of rows in the lifting order is equal to the number of rows in the weave design

What type of draft is used when the warp yarns pass through the heald frames in a staggered manner?

Mixed or staggered draft

What is characteristic of a regular reed plan?

Same number of ends per dent used throughout the width of the fabric

What is the term for the order of passing the warp yarns through different heald frames?

Drawing-in draft

What is the relationship between the weave design, DID, and lifting order?

They are strongly interconnected

What is possible to construct from a given weave design?

Both the lifting order and DID

What is constructed from the weave design and its drawing-in draft?

The lifting order

What is an alternative way to construct a weave design?

By changing the lifting order and keeping the DID constant

What is the term used to describe the process of constructing a weave design from a given lifting order?

Weave design construction
