The invention discloses a knitted natural red
pigment which is prepared from the following raw materials: red pepper, penstemon, clusteramaryllis, oriental variegated coralbean flower,
red maple, red leaf cherry plum, blackberry, purple sweet potato leftover, pitaya peel, rambutan peel,
lactic acid bacteria and
cellulose. The knitted natural red
pigment provided by the invention is simple in preparation, can be subjected to industrialized production, is extracted from pure natural
plant raw materials and is low in price, and the cost is saved by 17.4%. The red raw materials are fermented by
lactic acid bacteria, so that the acidity is regulated, the natural
aroma is increased, the
pigment extraction rate is improved by 8.3% compared with that of the conventional method, the pigment is kept bright for a long time, small molecular substances produced by
lactic acid bacterium
fermentation can promote
dyeing, and then the cloth is rapidly dyed and does not fade; and moreover, during
dyeing, only
distilled water needs to be added for diluting, only ultrasonic short-term soaking or spraying is needed, the operation is convenient and rapid, the working efficiency is improved, and the pigment is uniform in
dyeing, pure in color, unfading,
mildew-proof, mothproof, safe and environmental-friendly, can prolong the service life and contributes to
human health.
