aedafedd gorchuddio spandex?

Awyrcoverededafedd (Nylon 2030 pink air covered yarn) is a kind of yarn in which the outer fiber filament and spandex yarn are simultaneously drawn through a certain type of nozzle, and then the high compressed air is sprayed regularly to form rhythmic network points.The fabric feels soft and smooth;

spandex covered yarn (SCY) is the outer fiber filament constantly rotates and encircled on the core spandex which is drawn at uniform speed. It is twisted and has a twist (English abbreviation TPM). The main feature of the fabric is its flat and straight style

1.Q:What are the factors that affect the cladding quality of spandex covered yarn?

A:1. spandex wire draft multiple

2.Fineness of spandex filament

3.covering degree

4.Type of cladding process

2.Q:What is count?

A:Count，A unit used to indicate the thickness of a fiber or yarn.It is expressed as the length per unit weight of a fibre or yarn at a fixed moisture regain.(Cored wire) is usually divided into metric count and imperial count because of the different calculation units.

The strength elongation of Nylon 2030 pink air covered yarn increases with the increase of the predrafting ratio of spandex. When the drawing reaches a certain value, the retraction of spandex makes the outer fiber curl.When the predraft multiple is increased appropriately, the percentage of spandex is reduced and the curling degree of outsourcing fiber is large.However, when the draft is too large, the spandex deformation amplitude is close to the critical value of deformation, which will reduce the strength and elongation of the covered yarn, but is beneficial to the uniform drying of the covered yarn.
