Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to velor carpets in cut pile carpets.

Types of cut pile carpets that have been used in the past include jaggy carpets with twist set, sakin knee carpets, plain cut carpets that do not require twist set, and pencil boi carpets made of conjugate fibers.
Change the appearance form of the pile surface, such as pile veneer.

Although there are many types of carpets with different materials, in recent years, cut pile carpets have been increasingly used in tufting machines to create finer gauge carpets, and the development of velor carpets has been attracting attention.

All of these velor carpets require a splitting process using a fine gauge tufting machine or the like to eliminate the residual twist form of the pile yarns, and also to improve the velor-like appearance. In order to make hair splitting easier, the single fibers used in velor carpets are 10 to 15 deniers, whereas the single fibers used in cut pile carpets are 5 to 8 deniers. It tends to become thinner with denier. The texture is fine denier.

The splitting effect creates a soft feel, but the density decreases due to the shedding and cutting of the constituent fibers of the pile yarn during the splitting process, and the pile yarn becomes tilted due to the increased directionality of the pile yarn, resulting in 2 splitting and fine denier. This has caused problems such as carpet stiffness and products that do not have a feeling of pressure when stepped on.

The present invention aims to solve this problem, and its gist is that the tip of the pile yarn is cut and opened.

The base is a velor carpet consisting of untwisted staple fiber bundles bound by wound yarns.

The present invention will be described below with reference to nine drawings.

FIG. 1 is a side view schematically showing the velor carpet of the present invention. has been opened,
At the root portion (8), the non-twisted fiber bundle (3) is wound and restrained by a wound yarn (4). (6) is a secondary base fabric,
(5) shows each latex layer.

The middle part of the pile yarn (1) may be in a wound state depending on the type of winding yarn (4) used or if the pile surface has little separation.2 In the present invention, the winding in the middle part is The presence or absence of the condition does not particularly matter.

Next, an example of the manufacturing method of the present invention will be explained.

FIG. 2 shows a schematic side view of the yarn used to make the velor carpet of the present invention.

(3) shows a non-twisted fiber bundle, and (4) shows a wound yarn. As a manufacturing method, it can be obtained by guiding a spinning machine-spun fleece into a hollow spindle and winding the wound thread (4) around a bobbin attached to the hollow spindle. in this case.

The type of wound yarn (4) is not particularly limited.

The yarn thus obtained is tufted onto a base fabric to form a pile, which is then looped. In this case, the loop pile is cut, thereby resulting in an untwisted fiber bundle (
From 3), a pile yarn full Ω tip portion (7) is formed. The untwisted fiber bundle (3) forming the pile yarn (1) spreads in the width direction of the pile yarn (1) at the same time as the restraint of the wound yarn (4) is released.

The cut winding yarn (4) is reduced in the number of windings due to the spreading force of the non-twisted fiber bundle (3), while increasing the winding diameter (and increasing the winding diameter to near the base (8) of the pile yarn (1). I have to concentrate,
Only the untwisted fiber bundle (3) remains at the tip (7) of the pile yarn (1), forming a velor shape on the pile surface.

Furthermore, by passing through the coating and tenter dryer step, which is the post-process of carpet manufacturing, the carpet is heated at 100'C to 150°C, 5 to
By dry heat action for O minutes.

The crimp of the single fibers stretched during the spinning process is restored.

Furthermore, the looseness at the tip of the pile yarn (1) develops.

As described above, according to the present invention, the tips (7) of the pile yarns are untwisted and opened, so the splitting process used in conventional velor carpets is no longer necessary. The carpet surface is denser, and the pile thread root (8) is restrained by the winding thread (4), so
A velor carpet with an upright pile yarn (1) and good pressure feeling is obtained, and the tip (7) of the pile yarn (11) is formed from a non-twisted fiber bundle that is not twisted or restrained like a normal spun yarn. Because of this, the thickness of the single fibers ranges from 5 to 15 deniers, making it possible to achieve a remarkable velor effect.In addition, the excellent velor carpet appearance can be obtained without being limited to the material used.

Example 1 Mitsubishi Bonnell (acrylic fiber Mitsubishi Rayon (5) Co., Ltd. trademark) 10 denier x 127-152 50% Ryukyular dyed cotton and Mitsubishi Bonnell (same as above) 8 denier x 127-152 m conjugate dyeing After blending raw cotton with 50 pieces of cotton, it goes through a pre-spinning process. One side is usually semi-worsted and spun at a number 7 single yarn of 185 twists/m, and the other side is spun using a hollow spindle at 200 twists/m. Wind the polyester filament 50 denier/36 filament with the number of windings, spin the 7th yarn, and both points are 5764 inches G, 17 St/1nX 8 mP, Ho (800
Tufting was done with fine gauge J'/I).

The velor carpet of the present invention using a hollow spindle is
Although an excellent velor appearance was obtained by touch ink and shearing, the velor carpet made of normal semi-worsted spun yarn had a hard texture due to residual twist restraint in tufting and u-wool.

By the way, we usually use semi-worsted spun yarn carpet in velor style.
No. 0 wire density: 50 strands/in' z Key needle (6) When finished with 25 Orpm, the appearance was almost the same after passing twice, but there were many pile yarns that were pulled out (30!/m' of pile weight) This resulted in a decrease in hair loss and required an increase in the number of shearing steps.
