Concept of Denim Warping and Types of Denim Warping

Warping :

Normally there are two types of warping system followed in denim production. The first one is direct warping or beam warping, which collect the yarn in a sheet form onto a beam. In this warping, the yarn lies parallel to each other and in the same plane. This type of direct warping beam is suitable for dyeing in slasher dyeing in denim production.

Another type of warping is ball warping. In this warping, the yarns are brought together and collected into a rope before being wound onto a log.

Types of Warping :

The above two types of warping methods are briefly described below.

1. Ball Warping
2. Direct/Beam Warping

1. Ball Warping :

In ball warping process, individual strands of yarn are removed from yarn packages and collected into rope form suitable for rope dyeing (Fig.). Threads, about 350-500 in number are formed into ropes. Individual warp yarn are collected into rope form and wound onto a log and produce a ball warp on Ball warping machine.

2. Beam / Direct Warping :

In direct warping process, individual yarn from the package is removed and wind on to a beam in an open sheet form. Beam / direct warping maintains the yarns parallel to each other onto a slightly wider flanged beam. These yarns will go through slasher dyed or in an un-dyed fabric, which can be piece dyed, garment dyed, or left natural.
