Feb. 9, 1965 s. PLOCH ETAL VELVET-LIKE FILE} PRODUCTS Filed July 20. 1961 ATTORNEYS United States Patent 3,168,883 VELVET-LIKE PILE PRODUCTS Siegfried Ploch and Heinz Zschunke, Karl-Marx-Stadt,

Germany, assignors to Forschungsiustitut fur Textiltechnologie, Karl-Marx-Stadt, Germany Filed July 20, 1961, Ser. No. 125,443 2 Claims. (Cl. 112-411) This invention relates to a process for the production of velvet-like pile products for garments or industrial purposes.

The manufacture of velvet was effected up to now by weaving parallel juxtaposed tubes formed from the threads of the fabric or knitting ground with tubes formed from the binding pile threads. Subsequently, the pile threads of each tube are cut open and then loosened so that the piles form rib-shaped tufts when raised. This production method, however, requires a great expenditure of labor to obtain a sufficiently dense pile for various commercial purposes.

Recently methods for producing piles have been used wherein the weaving and knitting is eliminated to a great extent, and only used, if necessary, for the production of the ground cloth. The pile is formed here from tufts or thread loops, such as roving, chenille, etc., sewed or cemented to the ground cloth and cut open to form a pile.

These methods are suitable for the production of floor coverings, upholstery and similar fabrics, but they are not suitable for the production of velvet-like pile products since the resultant piles are not sufficiently dense or short for velvet. Besides, no tubes are formed in the semi-finished products that can be processed with conventional velvet cutting devices and finishing machines.

Therefore, an object of this invention is to inexpensively produce velvet-like pile products with desirable pile thicknesses, while maintaining compatibility with present velvet cutting and refining techniques.

Another object is to facilitate the production of velvetlike pile products.

According to the invention, transverse yarns or fiber fleeces are placed on a prefabricated ground such as a fabric, knitting or textile web, and bound to the ground with parallel longitudinal seams arranged side by side. The tubes thus formed between the seams are subsequently cut open so that the crude product obtained may be further processed according to known methods. The longitudinal seams can be produced by sewing and/or cementing, and by welding.

The sole figure of the drawing shows a section of a velvet-like pile product produced according to the process of the invention. Several steps of the manufacturing process can be seen in the drawing.

Yarns or fiber fleeces 2 are placed on a ground cloth 1 transverse to the longitudinal direction of the ground. The juncture between the ground 1 and the pile-forming yarns 2 is produced by longitudinally arrayed seams 3. The longitudinal seams 3 are arranged closely side by side in the manner of quilting seams and may be sewed to the ground by, for example, multi-needle machines. Since a very tight seam is necessary to obtain a particularly resistant velvet, the use of shrinkable sewing threads such as polyvinylchloride is advisable.

Tubes 4 are formed by the longitudinal seams 3 and subsequently cut open by means of cutting knives as shown at 5 in a manner known in the velvet manufacturing art. The tufted piles 6 may then be processed by finishing methods which are also known.

It is also possible to form the seam by cementing or welding. For example, the welding may be effected in a known manner by using strips of thermoplastic material or thermoplastic threads.

. Low-twisted rovings are preferably used as pile formmg yarns so that no fine spinning capacity is required, and to substantially reduce the brush passages required to loosen the fibers.

The process according to the invention has the additlonal advantage of eliminating the operations of cross winding and weft winding and of working directly from large-size roving bobbins. The efiiciency achieved by binding the pile directly to the ground is higher than that achieved by the present methods for manufacturing velvets. It also permits the construction of production lines for the manufacture of velvet using known velvet finishing machines and increasing considerably the producttv ty in the velvet finishing plant.

While a specific embodiment of the invention has been shown and described in detail to illustrate the application of the invention principles, it will be understood that the invention may be embodied otherwise without departing from such principles.

What is claimed is:

1. A velvet-like ribbed fabric comprising a ground cloth and a plurality of velvet-like ribs secured to an extenor surface of said cloth, each of said ribs comprising a plurality of closely adjacent rounded tufts of fibers, the tufts of each rib being separate and sewn to said exterior surface by a longitudinal threaded seam, the tufts in each rib being aligned in a direction transverse to said ribs with the corresponding tufts of the adjacent ribs.

2. velvet-like ribbed fabric according to claim 1, wherein said tufts are sewn to said exterior surface by means of a shrinkable thread.
