Description

[Detailed description of the invention] The present invention relates to cut pile carpets.

Conventional carpet types include saxoacre bed and velor carpet. The former is a cut pile carpet made by twisting and setting various types of carpet and applying it to pile yarn. The characteristic of the latter is that the pile surface fibers are not aggregated as threads, but are dispersed and have a delicate appearance, and are manufactured through a process such as splitting after planting, which is typical of pile threads. Although it has a fine and soft texture, it is a product that does not have a waist or pressure feeling.The present invention combines the waist and pressure sensation of Saxony carpet with the delicate texture that is characteristic of Bep Acarpet. The aim is to provide a new type of cut pile carpet that has both a good feel and appearance using a simplified manufacturing method, and the gist of this is to wind and restrain untwisted fiber bundles with shrink yarn. A method for manufacturing a cut pile carpet, which comprises planting a yarn as a pile yarn and then heat-treating the yarn in an atmosphere at a temperature equal to or higher than the contraction start temperature of the shrinkable yarn.

This will be explained in detail below with reference to the drawings.

FIG. 1 is a model diagram of the carpet of the present invention, where / is a pile yarn, C is a non-twisted fiber bundle, and 3 is a thread (hereinafter referred to as a winding yarn) that winds and restrains the non-twisted fiber bundle. , ), A is the tip g of the pile l made of untwisted Hata miscellaneous bundles, B
indicates the middle part and root part of the pile/ 0hiro is the primary base fabric, ! The characteristic of the carpet of the present invention is that the carpet of the present invention is made of a velor base fabric, as shown in FIG. . The intermediate and root portions B of the bail are restrained by a non-twisted IMM bundle (wound yarn 3), so the structure has excellent waist and pressure feeling.

The carpet manufacturing method of the present invention will be described in detail below.

Figure 1 shows a yarn (hereinafter referred to as "blade bird yarn") obtained by winding a non-twisted fiber bundle with a yarn (hereinafter referred to as shrinkable yarn) having a potential shrinkage capacity rt (hereinafter referred to as "shrinkable yarn") to be used as a pile of the carpet of the present invention. 6 O). The cover yarn 6 is a yarn (7) that guides the spun S-spun fleece to a rotating hollow spindle and is wound around a bobbin attached to the hollow spindle.
The present invention can be obtained by wrapping it around a wreath.
l@Curved yarn 61i using shrink yarn for thread 3
- After making cut pile cloth by a method such as tufting, weaving, or kneading, which is generally known as - use as a pile fabric, heat treatment is performed in an atmosphere above the shrinkage start temperature of the shrinkable yarn. Then, the shrinkable yarn shrinks along the bail made of fiber bundles and sinks from the tip of the bail to the middle part and the root g8 direction, but the wound yarn 3 is untwisted fiber It is desirable that the yarn thickness be 4 or less in the bundle. This is because if there is one person, the wound yarn 3 will be perceived from the carpet surface and it will be difficult to obtain an i*m outer appearance. In addition, it is desirable that the shrinkage rate of the wound yarn J is 10% or more to give the carpet stiffness.

Next, the cut pile carpet of the present invention can be manufactured through a normal carpet finishing process.□ As described above, according to the present invention, one pile/middle part and root W6B have a structure that exhibits a stiffness like that of a Saxony carpet. While having m, the tip of Bile/F! 6A was IL with the fine line look and feel of velor carpet! ! I-like carpet f: Obtainable ◎ Next, examples will be shown.

Actual example: 10MC wound on a V1 layered bobbin, shrinkage rate: O
% acrylic yarn is wound into a covered yarn by /sOT/M, and then the covered yarn is made into a - or inch G
Tufting was performed under the tufting conditions of J stX 1wmPH to obtain a cut pile cloth. When latex was applied to the back side of this cut pile cloth and dried in a tenter at 73θC, the wound yarn shrunk and sank from the pile surface.
Only untwisted fiber bundles were perceptible on the surface of the pile, giving a fine texture and appearance. In addition, the untwisted fiber bundles were strongly restrained by the winding threads in the middle and root parts of the pile, resulting in a stiff carpet.

[Brief explanation of the drawing]

Figures 1 and 2 are longitudinal cross-sectional views of the tooth part. At the base, Hiro is a 7th-order base fabric, and j is a 2nd-order base fabric.
