Blow Room:

The section where the supplied compressed bale is turn into a uniform lap of particular length by opening, cleaning, blending or mixing is called blow room section. It is the first steps of spinning.

Objects of Blow Room:

(i) Opening: Further opening of compressed cotton bale and cotton are made into small tufts.

(ii) Cleaning : To eliminate dust, dirt, broken leaf, seed particles, grass and other

.foreign impurities from the fiber.

(iii) Mixing and Blending: To produce a comparatively good quality cotton fibre by rmxrng

different types of cotton together.

(iv) To produce a uniform lap of particular weight per unit length.

(v) To convert the opened and cleaned fiber into a sheet of particular width

and uniform weight per unit length is called lap.

Basic Operations Involved in the Blow Room:

(i) Opening: Opening is the first operation in the blow room carried out to the stage of flocks in the blow room and to the stage of individual fibers in the cards.

(ii) Cleaning: To remove the impurities and foreign materials and the raw material as clean as possible.

(iii) Dust Removal: To remove dust which are completely enclosed in the flocks and hence are held book during suction.

(iv) Blending: To achieve the required quality of yam by blending different qualities of cotton into a particular ratio.

(v) Even Feed of the Material: To produce a lap of uniform weight per unit length or to process the cotton fiber to the maximum optimum quality which is suitable for carding.
