Technical Field

The invention relates to the technical field of carpets, in particular to a plain velvet carpet with high and low velvet feeling.

Background

The carpet is now gradually increasing with the global trend that plain weave carpets are passed through a printing process and are also gradually beginning to replace carpets such as jacquard carpets, welton carpets and the like which require a lot of time to be produced. However, most of the current plain-weave carpets are woven by a shuttle weaving process, but compared with carpets with velvet feelings in terms of foot feeling and velvet feelings, the plain-weave carpets have the advantages of smoothness, skin friendliness and good support performance of the felt face of the carpets without the velvet feelings. And a sizing process is usually used for the stability of the size, but the velvet feeling on the yarn is completely fixed, so that the rough hand feeling has certain risks for children playing on the yarn. The long pile carpet is easy to stick tiny garbage scraps and dust, and is not beneficial to keeping indoor cleanness, so that the flat woven carpet which can be conveniently folded and washed and has a skin-friendly hand feeling is needed.

In the prior art, the carpet can not be directly woven by the fabric of the clothes due to the reasons,

The chenille yarns, the first yarns, the second yarns and the third yarns are woven, and the chenille yarns, the first yarns, the second yarns and the third yarns are woven in an eight-way mode by an upper dial and a lower dial in a double-dial looping mode; the chenille yarns are knitted on the 1 st and 6 th ways, the first yarns are knitted on the 2 nd and 5 th ways, the looping positions of the chenille yarns and the first yarns are staggered, and the chenille yarns and the first yarns form the front surface of the fabric; the first yarn comprises a pile yarn; the second yarn is woven in the 3 rd path and the 7 th path to form the reverse side of the fabric; the third yarn is woven in the 4 th and 8 th paths and is connected with the front surface and the back surface of the fabric. However, a shrinkage phenomenon occurs after the cleaning. There is no way to improve the situation by ironing, which would otherwise result in a reverse and random pile of the fabric, which cannot be applied directly to the carpet. If it is used directly on a carpet, problems of foot warp, wavy edges, dimensional deformation occur. Chinese patent CN202543606U discloses a tufted carpet, especially a tufted carpet with three-dimensional pile face. Comprises a base fabric, wherein fluff is planted on the base fabric, different heights are arranged according to regions, the fluff with different heights forms a step-shaped three-dimensional suede, and the number of layers of at least one step in the step-shaped three-dimensional suede is equal to or more than 3. Although the step-shaped three-dimensional suede with more than 3 layers ensures that the whole suede has rich three-dimensional layering; but it is difficult to clean and even to put into a washing machine for washing.
