What is Carding? Carding is an initial stage of cotton spinning. It is defined as the reduction of entangled mass of fibres to filmy web by working them between two closely spaced relatively moving surfaces (flats and cylinder) closed with wires. For this, the imperfect fibres and other impurities have to be removed.
Principle of texturing - TEXTURING is a treatment in which flat filaments are distorted to have loops, coils, curl or crimps along their length to gain increased bulkiness, porosity, softness and elasticity in some situations.

CAMEL FIBRE Bactrian camels have two coats, a long and hairy outer coat and a soft and downy inner coat. The outer fibre is used for making ropes and also strong yarn used in the warp of rugs. The inner down is considered a luxury fibre and it is very warm and light, it has some elasticity, but it is not very elastic. Use camel down when you want warmth without bulk, a characteristic that makes camel coats popular.
The ROVING FRAME RIETER The chief task of the roving frame is the attenuation of the sliver. Since the resulting fine strand has scarcely any coherence, protective twist must be inserted in order to hold it together. The third task cannot be directly attributed to spinning: it lies in winding the roving into a package that can be transported, stored and donned on the ring spinning machine.
COVERED YARNS have a core yarn this is completely covered by fiber or another yarn. Figure 14 shows different types of covered yarns. The core might be an elastomeric yarn, such as rubber or spandex, or yarns, such as polyester or nylon. Covered yarns may have either a single covering or double covering. The second covering is usually twisted in the direction opposite from the first covering.
