Definition statement

This place covers:

Apparatuses and methods for stretching, tentering or spreading textile fabrics.

Glossary of terms

In this place, the following terms or expressions are used with the meaning indicated:

Tentering

sets the warp and weft of woven fabrics at right angles to each other, and stretches and sets the fabric to its final dimensions. The fabric is stretched by the use of a tenter frame, consisting of chains fitted with pins or clips to hold the selvedges of the fabric, and travelling on tracks. As the fabric passes through a heated chamber, creases and wrinkles are removed, the weave is straightened, and the fabric is dried to its final size.

Synonyms and Keywords

In patent documents, the following words/expressions are often used as synonyms:

  • "tentering", "crabbing" (i.e. tentering wool) or "heat-setting" (i.e. tentering synthetic materials)
  • "spreading", "stretching", "expanding", "widening" or "enlarging"
by rotary disc, roller, or like apparatus

Beetling
Glossary of terms

In this place, the following terms or expressions are used with the meaning indicated:

Glossary of terms

In this place, the following terms or expressions are used with the meaning indicated:

fulling

is a finishing process used usually in the manufacture of woolen and worsted fabrics. The cloth is subjected to moisture, heat friction, chemicals, and pressure which cause it to mat and shrink appreciably in both the warp and filling directions, resulting in a denser, more compact fabric.

Breaking or softening of fabrics (by stretching D06C 3/00; by calendering, pressing, or beetling D06C 15/00; by fulling D06C 17/00)
Definition statement

This place covers:

Apparatuses and methods for breaking or softening of fabrics.

Shrinking by compressing
Definition statement

This place covers:

Compressive devices and corresponding methods carrying out the shrinking action by transporting the fabric between a moving elastic belt and a rotating heated drum, whereby the elastic belt is partially wrapped around the heated drum (called also " sanforizing")

Devices for microcreping. Microcreping, sometimes called "dry microcreping", refers to longitudinal treatment of travelling fabric under substantially dry conditions in which a drive force is produced by pressing the fabric against a drive roll. This positively propels the material through a confined retarding passage, with microcreping action on the material occurring in the transition between driving and retarding regions. Because such microcreping does not depend upon adhesion of the material to the drive surface or a wet condition of the material, a particularly wide range of properties is obtainable. Note that the dry microcreping here must not be confused with wet creping or creping based on adhesion, performed for instance on a Yankee dryer.

Special rules of classification

Wet creping or creping based on adhesion performed for instance on a Yankee dryer.
