Description

  The present invention is a technique for imparting design properties to felt yarns as pile yarns used for interior fiber floor materials such as mats, rugs and carpets.

  Formerly, sliver-like wool fibers are mixed with heat and moisture, and the fibers are intertwined by striking and kneading while applying pressure, which is called a felt yarn. Carpets with a luxurious and volume feeling are provided by using 0th-thick extra-thick yarn as pile yarn for interior fiber floor materials such as carpets.

  However, since felt yarn is made without twisting using the properties of wool fiber, it is not often twisted together with other fibers or colored yarns to obtain design, dyeing, etc. In many cases, the yarn is dyed in a yarn state or a pile yarn state.

  In the patent document 1, the felt yarn processed by adding warm water to a sliver containing at least 50% or more of wool fibers in Patent Document 1, and the decorative yarn made of wool or a different material is aligned with the sliver and felt processed. A felt yarn imparted with design characteristics characterized by the above is disclosed.

  However, the felt yarn disclosed in Patent Document 1 is an excellent technique for imparting design properties to the side surface of the yarn, and is useful for carpets of a standard that mainly displays the side surface of the yarn while lying on the pile yarn. However, it was not very meaningful for carpets with a standard that showed the cut surface of pile yarn. In addition, as a carpet of the standard that shows the cut surface of the pile yarn, for example, a pile yarn in which low-melting fibers mixed with different colors are twisted and heated to melt and fix the low-melting fibers can be mentioned. There has not yet been a carpet of a standard that shows a cut surface of a pile yarn made of felt yarn having a core-sheath structure as in the present invention.

JP 2002-194632 A

  This invention makes it a subject to provide the designability to the cut surface of a pile yarn, and exists in providing the carpet which is not in the past.

  The present invention provides the following means in order to achieve the above object.

  [1] In a felt yarn that is processed while adding warm water to a sliver containing at least 50% or more of wool fibers, the decorative yarn made of wool or a different material is felt processed so as to be located inside the sliver, and the core-sheath structure Felt yarn characterized by that.

  [2] In a felt yarn manufacturing method in which warm water is added to a sliver containing at least 50% of wool fiber, the felt yarn is processed so that a decorative yarn made of wool or a different material is located inside the sliver, A felt yarn manufacturing method characterized by having a core-sheath structure.

  [3] A carpet in which the felt yarn imparted with the design property according to item 1 is used for a part or all of a pile yarn.

  In a sliver containing at least 50% or more of wool fiber, the decorative yarn made of wool or different materials is placed inside the sliver and felted by adding warm water. It is possible to obtain a felt yarn having a core-sheath structure by being entangled and fixed in a wool fiber bundle so as to be wrapped inside.

  Further, the carpet using the felt yarn as a cut pile yarn has a design property on the cut surface of the pile yarn, and can be made into a carpet with an unprecedented feeling. Furthermore, if the decorative yarn is a combination of different fibers and yarns, which are called design yarns, or if the shape and color scheme are changed, the expression of the decorative yarn on the cut surface of the pile yarn will be rich. The carpet can be rich in design.

  The present invention is a technique for imparting design properties to felt yarns as pile yarns used for interior fiber floor materials such as mats, rugs and carpets. Examples of the form of the interior fiber floor material include woven fabrics, knitted fabrics, and napped fabrics such as tufted carpets. The fiber of the interior fiber flooring is not particularly limited, but unless it is a sliver containing at least wool fiber, it is felted and is not entangled and fixed in the wool fiber bundle so as to wrap the decorative yarn. The blending ratio of wool fibers is preferably 50% or more, and the fibers other than the wool fibers to be blended are not particularly limited, but synthetic fibers such as polyester, polyamide and acrylic, semi-synthetic fibers such as acetate and rayon, silk and cotton It can be used by mixing with one or more fibers selected from natural fibers such as hemp.

  The sliver is generally an intermediate product in the spinning process, and refers to a fiber bundle that is not twisted before the spinning process, and is also called Shino.

  The mechanism of the present invention utilizes the property that, when a lump of wool or a woolen fabric is wetted with water and kneaded, the fibers become entangled and contract and become hard. The surface of the wool has a structure covered with what is called a scale like a fish scale. The friction coefficient from the hair root to the hair tip direction is low, and the friction coefficient from the hair tip to the hair root direction is high. That is, it has the property of being slippery in the hair tip direction and not slipping in the hair root direction. When this group of wool fibers is wetted with water, it begins to move unilaterally in the direction of the hair root and utilizes the property that the wool fibers are entangled and contracted.

  Prior to the felt yarn manufacturing process of FIG. 1, the sliver is pressed flat, and the decorative yarn 3 made of wool or different materials is stacked on the sliver, while the feeding amount of the sliver 1 is larger than the feeding amount of the decorative yarn 3. Then, twisting is performed so that the decorative yarn 3 is wrapped inside the sliver 1.

  The decorative yarn 3 imparts design properties to the felt yarn and is not particularly limited, but is preferably a yarn in which different fibers or yarns called design yarns are combined, or the shape or color scheme is changed. Decorative yarns with a sharp change in shape cause thread breakage when weaving carpets, resulting in a decrease in weaving properties.In the case of the present invention, wool fibers wrap and entangle the decorative yarns. It is difficult to form a shape that protrudes out of the system, and it is difficult to cause thread breakage. The material of the decorative yarn is not particularly limited and is made of wool or a different material. The shape is not particularly limited, and may be a thread in which a decorative resin such as a bead is fixed to the thread or a thread having a large nep, and may be wrapped and fixed in a sliver.

  Next, as shown in FIG. 1, the sliver 1 processed so that the decorative yarn is positioned inside the sliver is fed to the pipe 5 by the feed roll 2 at a constant speed. When the hot water 6 (60 ° C. to 70 ° C.) is sent from the pipe wall surface to the sliver 1 fed into the pipe 5 and squeezed by the kneading roller 8, condensation (entangles and shrinks) on the wool fibers, The decorative yarn 3 is fixed to the sliver 1 and felted.

  The felt yarn 7 to which the decorative yarn 3 is fixed is taken up by a take-up roll 9 (squeezing roll), dried and wound up.

  The pipe 5 is a pipe having a diameter of 4 to 6 mm and a length of 40 to 80 cm of vinyl chloride, and has a structure in which the hot water 6 is poured from the middle along the yarn path. When the sliver containing wool fiber is rubbed with the warm water 6 and the squeezing roller 8, it becomes felt and becomes a felt yarn.

  The hot water 5 from the pipe wall surface is preferably 60 ° C. to 70 ° C., and is preferably poured so as to involve a sliver. Moreover, the hot water 5 may be blown from one place on the wall surface of the pipe, or may be poured sequentially from several places.

  The kneading rollers 8 are set so as to move up and down, left and right, and obliquely, respectively, and work to squeeze the sliver 1 passing through the pipe 5 while bending or stretching the pipe.

  FIG. 2 is an enlarged schematic view of the felt yarn imparted with designability according to the present invention applied to a tufting machine to be stabbed into the base cloth 4 to form a carpet. The decorative yarn is entangled with the wool fibers that exhibit condensation, and is fixed in the sliver, and has a sufficient strength as a carpet pile yarn, and a voluminous carpet with excellent design is woven.

<Example 1>
A 40% acrylic fiber and 60% wool fiber were blended, and a 0.4th sliver was obtained with a roving machine. Next, prepare a 3rd polyester spun yarn NEP yarn as a decorative yarn, hold the sliver flat and layer the decorative yarn, and increase the sliver feed amount by 1.5 times the decorative yarn feed amount. However, twisting was performed and processing was performed so as to wrap the decorative yarn 3 inside the sliver 1. The sliver having the core-sheath structure thus formed is fed into the pipe, hot water of 65 ° C. is fed from the pipe wall surface, and is applied to the sliver, and the wool fibers are condensed by wrapping the decorative yarn with a kneading roller. ) And dried to obtain a slab yarn having a design property.

  Next, using this slab yarn, a carpet having a pile length of 20 mm and a stitch of 8/10 cm was prepared using a 5/16 gauge cut pile tufting machine. There was no yarn breakage, the weaving property was good, and a design-like carpet with a cut surface was obtained.

  The technology of the present invention can easily obtain an extremely thick wool yarn having a design with an unprecedented cut surface characteristic without going through a twisting process, and is widely used for interior goods such as curtains and carpets.

It is the schematic of the manufacturing process which concerns on one Embodiment of this invention. It is the schematic of the carpet which concerns on one Embodiment of this invention.
