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 containing heat and moisture, struck or squeezed while applying pressure, and the fibers entangled and hardened into a thread form are called felt yarns. 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 Patent Document 1, in order to impart designability to a wool fleece (non-twisted fiber bundle), a structure in which a wool fleece and different or similar fiber filaments other than wool are twisted in the same direction with the same number of twists Is disclosed, can reduce the fuzz of the wool without impairing the texture of the wool, can improve the entanglement of the wool fleece and other fiber filaments, the form stability and the leveling of the alignment state, Techniques have been disclosed that clearly express the tonal hue and improve the feel and surface properties of the woven fabric.

  In Patent Document 2, as a technique for imparting design properties to the yarn, the number of twists, the twisting direction, and the feed amount are adjusted by using the core yarn and the decorative yarn, and it has a span tone, a wool tone and a soft feeling. Slab yarn manufacturing technology is disclosed. Any of these methods is a method of adding twist, and is a widely known technique for imparting design properties to a yarn.

  However, the method of twisting as in the above method requires a twisting step, and the method of twisting a very thick yarn such as felt yarn is thin and loses a sense of volume. The object of the present invention is to provide design properties while maintaining the felt volume of the felt yarn, and to align a special yarn (decoration yarn) containing a nep or having a large unevenness in thickness on the felt yarn. The object is to provide a felt yarn whose weaving property does not change even if it has a design.

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

  [1] A design characteristic of a felt yarn that is processed while adding warm water to a sliver containing at least 50% or more of wool fiber, and a decorative yarn made of wool or a different material is aligned with the sliver and felt. Felt yarn granted.

  [2] In a felt yarn manufacturing method in which warm water is added to a sliver containing at least 50% or more of wool fiber, the felt is formed by aligning wool or a decorative yarn made of a different material with the sliver. A method for producing felt yarn with added properties.

  [3] A carpet using the felt yarn imparted with the design property described in the preceding item 1 for a part or all of the pile yarn.

  Warm water is added to a sliver that contains at least 50% wool fiber, and at the same time, decorative yarn made of wool or different materials is drawn to the sliver and felt to make it possible to hold the decorative yarn without going through the twisting process. It is possible to obtain a felt yarn that is entangled and fixed in the fiber and has a design property.

  Further, the carpet using the felt yarn as a pile yarn has a design property, and can be a luxurious and volume-like carpet.

  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. The form of the fiber flooring for interior is not particularly limited, such as a woven fabric, a knitted fabric, or a raised fabric such as a tufted carpet. 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 so that the decorative yarn is held. The blending ratio of wool fibers is preferably 50% or more, and the fibers other than 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.

  FIG. 1 is a schematic view of a process for producing the felt yarn of the present invention. A sliver 1 containing wool fibers is fed to a pipe 5 at a constant speed by a feed roll 2. The decorative yarn 3 is fed between the feed roll 2 and the pipe 5 by the feed roll 4 with 0 to 6% overfeed. When hot water 6 (60 ° C. to 70 ° C.) is sent from the pipe wall surface to the sliver 1 and the decorative yarn 3 fed into the pipe 5 and squeezed by the kneading roller 8, it condenses (shrinks by entanglement) with the wool fibers. Is expressed and felt on the sliver 1 so as to surround the decorative yarn 3.

  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 decorative yarn 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 and color scheme are changed. Decorative yarns with a sharp change in shape cause thread breakage when weaving carpets, resulting in a decrease in weaving. However, in the present invention, wool fibers are entangled so as to wrap the decorative yarns. This is unlikely to project 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 it may be a thread in which a decorative resin such as a bead is passed through the thread or a thread having a large nep, and it may be wrapped in a felt yarn and fixed.

  It is preferable that the feeding speed at which the decorative yarn is fed out is 0 to 6% overfeed of the sliver feeding speed. If the decorative yarn is supplied without overfeeding, the tension yarn tends to occur on the felt yarn, and a good yarn may not be obtained.

  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 view of the felt yarn having the design property of the present invention applied to a tufting machine to form a carpet. The decorative yarn is fixed to the sliver while being entangled with the wool fiber that has developed condensation, and a carpet having a sufficient volume and a sense of volume that has sufficient strength as a pile yarn of the carpet 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, as a decorative thread, 3% polyester spun yarn nep yarn is over-feeded 3% and fed into the pipe together with the sliver. It was kneaded to condense the wool fiber, and it was picked up by a take-off roll 9 (drawing roll) and dried to obtain a slab yarn having a design property.

  Next, using this slab yarn, a shaggy type carpet having a pile length of 45 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 carpet with a design property could be obtained.

  The technique of the present invention can be obtained easily without going through a twisting process, and is widely used for interior goods such as curtains and carpets.
