2. Description of Related Arts
Velvet plush has a generally soft and smooth texture and is a very popular material used in textiles. Velvet plush throws, blankets, and similar plush textiles are in popular use because they are very smooth and soft. However, the cost to manufacture a velvet plush throw, blanket or the like is very high. Conversely, efforts to manufacture velvet plush throws and blankets at more reasonable cost have resulted in lower quality articles. Materials such as silk, cashmere, mohair, linen and cotton are traditionally used for manufacturing velvet plush. Velvet plush articles produced from silk are especially soft and smooth. Silk, however, is a very expense raw material and is, therefore, less desirable when seeking to contain manufacturing costs. On the other hand, synthetic materials such as polyester and nylon are more reasonable in price, but the quality of a velvet plush cloth made with polyester or nylon is relatively low.
The conventional method for manufacturing a tufted surface involved needling and adding the tufted pile onto a backing, but this technique does not produce a smooth and soft tufted surface of high quality having an evenly distributed pile layer.

the shearing process includes shearing in frontward, backward, backward, frontward, frontward, frontward, backward and backward directions, sequentially, such that the final orientation of the pile hair is the same when approaching the cloth in both frontward and backward directions; and
the final heat-setting process includes heat-setting at approximately 190° C. at a rolling speed of 30 m/min.
13. A method of manufacturing a velvet plush article, comprising the steps of:
weaving a greige cloth by interweaving face yarns and backing yarns, said face yarns comprising single-ply trilobal yarns or two-ply yarns and said backing yarns comprising fully drawn yarns or draw-textured yarns;
pre-processing by sequentially brushing, first setting, singeing and second setting said greige cloth;
dyeing the pre-processed greige cloth to form a colored cloth; and
finishing by sequentially softening, drying, brushing, first heat-setting, singeing, shearing and final heat-setting said colored greige cloth to form a finished velvet plush article having pile hair that is uni-directional, smooth and soft.

17. The method of claim 13 wherein said face yarns and said backing yarns have a ratio of 4:1 by weight.
18. The method of claim 13 wherein
said brushing process during pre-processing includes brushing in a frontward direction and brushing in a backward direction;
said first setting process includes heat-setting between approximately 120-130° C. at a rolling speed of 25 m/min;
said singeing process during pre-processing includes passing the greige cloth across hot singe rollers in frontward, backward, backward, frontward, backward and backward directions, sequentially; and
said second setting process includes heat-setting between approximately 170-180° C. at a rolling speed of 25 m/min.
19. The method of claim 13 wherein said dyeing step comprises the substeps of:
bathing said pre-processed greige cloth in a dye solution fluid, and
neutralizing the pH or lowering the acidity of said greige cloth to give the dyed greige cloth a smooth and bright surface.
20. The method of claim 13 wherein
the softening process includes:
washing to add acidity until the greige cloth is soft, and
neutralizing the pH of the acidified greige cloth;
the drying process includes drying at approximately 190° C. at a rolling speed of 20 m/min with an upper drying channel operated at 300 rpm and a lower drying channel operated at 1200 rpm;
the first heat-setting process includes heat-setting at approximately under 150° C. at a rolling speed of 25 m/min;
the singeing process during finishing includes passing said greige cloth across hot singeing rollers in backward, backward, frontward, frontward, backward, frontward, backward and frontward directions, sequentially;
the shearing process includes shearing in frontward, backward, backward, frontward, frontward, frontward, backward and backward directions, sequentially, such that the final orientation of the pile hair is the same when approaching the cloth in both frontward and backward directions; and
the final heat-setting process includes heat-setting at approximately 190° C. at a rolling speed of 30 m/min.
