Description

[Detailed description of the invention] The present invention is composed of a core yarn made of filaments with a large fineness and a knitting yarn made of filaments with a fineness smaller than that of the filaments constituting the core yarn, and is soft and bulky. This invention relates to a bulky textured yarn that is rich and has excellent post-processability.

In general, multifilament yarns have a cold feel or a unique slimy feel compared to spun yarns, and fabrics knitted and woven with multifilament yarns have the drawbacks of low heat retention and lack of warmth in both texture and appearance. are doing.

In contrast to multifilament yarns having these drawbacks, bulky yarns made of multifilament yarns and having loops, coils, tangles, etc. arranged irregularly along the length of the yarn are well known.

Even when fabrics were knitted with this type of bulky yarn known up to now, the fabrics were somewhat lacking in bulkiness.

Therefore, when trying to increase the bulkiness of the fabric,
When manufacturing such bulky yarn, the overfeed rate of the multifilament yarn is increased, or the overfeed rate of the knitting yarn is increased with respect to the core yarn by using two yarns, the core yarn and the knitting yarn. Large bulky yarns such as loops, coils, and tangles obtained by

When such bulky yarn is unwound from a package, it can become entangled, rub against each other, or get caught, causing large fluctuations in unwinding tension. Also, when unwound at high speed, yarn breakage can occur, and the yarn itself can also be damaged. The fabric was stretched, causing loop spots and knitting defects, which significantly impeded the operability of subsequent processes such as turning, knitting and weaving.

Furthermore, even after fabrication, the loops protrude from the surface of the fabric, and when the fabrics are stacked, the loops become entangled and stick together, a so-called Velcro phenomenon, resulting in poor consumption performance.

The present invention aims to eliminate the drawbacks of conventional bulky yarns, to provide bulky yarns that are rich in bulky properties and have excellent post-processability, and which do not lose their bulky properties even after being made into fabrics.

In order to achieve this object, the present invention has the following configuration.

That is, the present invention has a core yarn consisting of a filament of 2.0 to 12.0 deniers and a filament of 0.3 to 1.1 denier.
a knitting yarn made of filaments having a denier or less, the length of the knitting yarn is 10% or more longer than that of the core yarn, and the weight ratio of the core yarn to the knitting yarn is 20%.
: 80 to 80 : 20, and furthermore, the core yarn occupies the center part of the yarn, and the sliding filaments are entangled around the core yarn, and the sliding filaments are entangled and entangled with each other to form the entire system. as loop, coil,
It is a bulky processed yarn characterized by the formation of tangles.

Next, the present invention will be explained based on the drawings.

FIG. 1 is a schematic diagram of the bulky textured yarn of the present invention.

In the figure, A is a filament of 2 or more denier that constitutes the core thread, B is a filament of 0, 3 or more denier that constitutes the sliding wire, and 1
．． It is a filament of less than 1 tenth.

Here, the core yarn consisting of a large number of filaments 1 to A occupies the central part of the bulky yarn C and is quite straight, whereas the filament B that forms a sliding electric current occupies the central part and is quite straight. The filaments B and B are intertwined with each other to form loops, coils, tangles, etc.

Here, while the fineness of filaments used in conventional loops of bulky yarn is generally 1.5 denier or more, in the present invention, the fineness of filament B constituting the sliding wire is 0.3. ~1.1 denier.

This is a filament I with a significantly smaller fineness than the conventional one.
- By adopting a sliding wire consisting of B, the resistance caused by loops, coils, tangles, etc. that protrude from the thread body are reduced, and even if loops, coils, tangles, etc. become entangled, they can be easily removed. This is to prevent fluctuations in unwinding tension and the Velcro phenomenon in the fabric, which were problems in the past.

Furthermore, since the surface of the bulky textured yarn C is covered with fine denyl filament L-B, a soft texture unique to fine denyl can be obtained.

In order to obtain soft and good unwinding characteristics, the fineness of the filament (1-Bcr) constituting the sliding wire is limited to 1.1 tenier or less.

However, if the fineness is less than 0.3 denier, the bulky feel will be reduced even if loops are formed, and it will be disadvantageous in terms of cost, so the fineness is limited to 0.5 denier or more.

In addition, the filament) B may have the same fineness or different fineness, and in short, the filament (Filamen) B may have a fineness of 0.3 or more and a fineness of 1°1.
It has a fineness of less than 100 ml.

Next, the filament A that makes up the core yarn is 2.0 to 12.0.
It has a ten-neal fineness.

Since the filament 1-B that makes up the sliding wire is thin, less than 1.1 denier, the fabric can be kneaded with just one soft cloth in the field. It has a soft texture.

This is to prevent such drawbacks.

In other words, if it is less than 2.0 degrees, you will lose your waist,
On the other hand, if the denier exceeds 12.0 denier, the core yarn becomes moderately difficult to twist, and the sliding conductor is not entangled with the core yarn.

Further, the core yarn is also made of filament A of the same or different fineness.

Furthermore, the thread length of the sliding wire must be at least 10% longer than that of the core thread.

This is to form appropriate loops, coils, tangles, etc. on the surface of the exposed and bulky processed yarn C.

In addition, the weight ratio of the core thread and the sliding wire is 20:80 to 80.
:20 is to ensure a fabric with soft, bulky and firm texture, as well as to improve unwinding properties and prevent the Velcro phenomenon.

Furthermore, the reason why only the sliding conductors substantially form loops, coils, tangles, etc. is to improve the unwinding property and prevent the Velcro phenomenon of the fabric.

Next, the materials for the core yarn and the sliding wire are not particularly limited, and may be bossester fibers, polyamide fibers, polyacrylonitrile fibers, acetate, rayon, protein-acrylonitrile copolymer fibers, or composite fibers thereof. .

Further, these materials may be a combination of filaments having different properties, such as gloss, dyeability, cross-sectional shape, shrinkage rate, or strength and elongation.

FIG. 2 is a schematic side view of an apparatus for producing bulky textured yarn of the present invention.

In the figure, 2.0 to 12.0 tenyl filament)
The multifilament yarn Y consisting of A is unwound from the package 1 and sent to the fluid nozzle 8 provided between the 10th lager 4 and the 20th lager 5 which rotates at a surface speed 5 to 20% slower than the 10th lager 4. Supplied.

On the other hand, filament 1 in the range of 0.3 to 1.1 tenier
The multifilament yarn Y' consisting of ~ Supplied.

In the fluid nozzle 8, the filaments 1-B constituting the multifilament yarn Y' are entangled around the multifilament yarn Y serving as the core yarn, forming an entangled loop, a coil,
Bulky textured yarn C is produced by forming entanglements.

Here, 3.3', 9 is a guide, 6 is a winding drum, and 7 is a package.

As described above, the bulky yarn of the present invention has excellent post-processing properties such as unwinding ability, and even after being made into a fabric, it has a firm and bulky property, and has the remarkable effect of almost no Velcro phenomenon. It is.
