1. Field of Invention
The present invention relates to velvet plush, and more particularly to a method of manufacturing velvet plush throw which utilizes synthetic fiber to produce a particularly soft and smooth velvet plush throw.
2. Description of Related Arts
Velvet plush has a generally soft and smooth texture and is a very popular materials used in textiles. Recently, velvet plush throw, blanket or the like is very popular in regular household use because its softness and smoothness provides a very great feel and touch sensation to a user. However, in order to manufacture a velvet plush throw, blanket or the like with superior feel and touch sensation, the cost of manufacture is very high. On the contrary, in order to manufacture a velvet plush throw and blanket with reasonable manufacture cost, the quality of the velvet plush throw is low. There is no way to manufacture a high quality velvet plush throw with a cost-effective method.
For example, silk is the traditional material which provides superior softness and smoothness. However, silk is also a very expensive raw material and therefore it is not an option when manufacturing cost is a concern.
On the other hand, synthetic materials such as polyester and nylon are more reasonable in price. However, the quality of a velvet plush cloth made in polyester or nylon is relatively low.
Conventional method for manufacturing a tufted surface involves needling and adding the tufted pile onto a backing, which is also incapable of providing a smooth and soft tufted surface of high quality with evenly distributed pile layer.
The invention is advantageous in that it provides a method of manufacturing velvet plush which can utilize synthetic materials to produce a high quality velvet plush article.
Another advantage of the invention is to provide a method of manufacturing velvet plush which can utilize synthetic materials to produce a velvet plush article having superior smoothness and softness so as to provide a superior touch and feel comfort.
Another advantage of the invention is to provide a method of manufacturing velvet plush which can utilize synthetic materials to produce a velvet plush article through an automated process with lowered cost and higher quality.
Another advantage of the invention is to provide a velvet plush article through a method of manufacture thereof so as to provide a velvet plush article having superior smoothness and softness while providing flexibilities in dyeing and printing.
Another advantage of the invention is to provide a velvet plush article through a method of manufacture thereof so as to provide a velvet plush article having superior smoothness and softness so as to provide a superior touch and feel comfort.
Additional advantages and features of the invention will become apparent from the description which follows, and may be realized by means of the instrumentalities and combinations particular point out in the appended claims.
According to the present invention, the foregoing and other objects and advantages are attained by a method of manufacturing a velvet plush article, comprising the steps of:
(a.1) weaving a greige cloth by interweaving face yarns and backing yarns, wherein the face yarns are selected from a group consisting of single-ply bright trilobal yarns with 75D/144F, 90D/144F, 100D/144F or 150D/288F and two-ply yarns with 120D/288F-300D/574F, wherein the backing yarns are selected from FDY 68D-100D or DTY 100D-150D;
(b.1) pre-processing the greige cloth obtained from step (a) by brushing, first setting, singeing and second setting the greige cloth sequentially;
(c.1) dyeing the greige cloth after step (b.1) to form a colored greige cloth; and
(e.1) finishing the colored greige cloth by softening, drying, brushing, stentering, heat-setting, singeing, shearing and final heat-setting the colored greige cloth.
Alternately, after the step (b.1) or (c.1), the method of manufacturing a velvet plush article further comprises the steps of:
(d.1) printing the greige cloth obtained from the step (b.1) or printing the colored greige cloth obtained from the step (c.1) to form a printed greige cloth; and
(e.1) finishing the colored greige cloth or the printed greige cloth by softening, drying, brushing, stentering, heat-setting, singeing, shearing and final heat-setting the colored or printed greige cloth sequentially.
Preferably, in step (a.1), a first and a second filaments are provided and a ratio of the first filament to the second filament is 4:1, wherein the first filament is a backing filament.
Preferably and in particular, in step (b.1), the brushing involves brushing along a frontward direction as well as brushing at a backward direction; the first setting involves heat-setting at 130-120° C. at a rolling speed of 25 m/min; the singeing involves a sequential rolling for six times at a frontward, backward, backward, frontward, backward and backward directions; the second setting involves heat-setting at 170-180° C. at a rolling speed of 25 m/min.
In particular, in the step (c.1), dyeing the greige cloth includes bathing in dye fluid and rinsing by water. Preferably, an additional dyeing time is required for bathing and a pH of the water for rinsing is neutral or has a lowest acidity for providing a smooth and bright surface. The additional dyeing time for bathing is 20 minutes.
In particular, in the step (d.1), printing includes the steps of brushing at a frontward direction, setting at 150° C. at a rolling speed of 25 m/min, and printing a preset pattern.
Preferably, in the step (e.1), softening includes washing to add acidity until the greige cloth is soft and then neutralizing the greige cloth until a pH of the greige cloth is neutral. It is worth mentioning if the pH is smaller than 7, then hair loss will occur. If the pH is greater than 7, the greige cloth will be hardened; drying includes drying under 190° C. at a rolling speed of 20 m/min with an upper drying channel operated at 300rpm and a lower drying channel operated at 1200 rpm; brushing includes brushing for two times; stentering includes stentering at a frontward direction and a backward direction;
heat-setting includes heat-setting under 150° C. at a rolling speed of 25 m/min with soft air; singeing includes singeing at a frontward direction and a backward direction, and preferably includes singeing at a backward, backward, frontward, frontward, backward, frontward, backward and frontward directions sequentially; shearing includes shearing at a frontward, backward, backward, frontward, frontward, frontward, backward and backward directions sequentially such that the final direction of the hair at a frontward direction and at a backward direction are the same; and final heat-setting includes heat-setting at 190° C. at a rolling speed of 30 m/min.
In accordance with another aspect of the invention, the present invention comprises a velvet plush article, comprising:
a flat body having a middle layer defining a top surface and a bottom surface, and at least one pile layer extended from the middle layer on one of the top surface and the bottom surface,
wherein the velvet plush article is made in synthetic materials such as polyester and the pile layer provides a highly smooth and soft touch and feel to a user.
Preferably, a color and/or a pattern is provided to the flat body of the velvet plush article. It is worth mentioning that the velvet plush article can also be a velvet plush blanket or simply a velvet plush sheet for further processing.
Still further objects and advantages will become apparent from a consideration of the ensuing description and drawings.
