Abstract

PURPOSE:To obtain light-weight design yarn having a feeling of bulkiness by subjecting specific wool fibers and raw cotton to woolen spinning to give untwisted yarn and subjecting filament yarn comprising the untwisted yarn as core yarn to lily yarn processing. CONSTITUTION:Wool fibers of merino wool having 56-68's fineness and natural raw cotton or chemical staple fibers having <=10cm cut length and <=5 average denier are subjected to mixed spinning to give untwisted yarn having <=1/10 spinning count. The untwisted yarn is twisted with water-soluble yarn (e.g. Vinylon(R) having 40 denier) and used as core yarn to give filament yarn or spun yarn having >=30 denier. Then the filament yarn is subjected to lily yarn processing and the water-soluble yarn is dissolved to give the aimed design yarn.

Description

DETAILED DESCRIPTION OF THE INVENTION □Top Q: ULmJ) UL The present invention relates to a designed yarn using spun yarn and a method for producing the same.

Shirai Hama□Hinoki Suke Generally, the raw yarns used for knitted clothing fabrics are spun yarns, filament yarns, designed yarns, etc. Especially for middle or low gauge knitted fabrics of 7 gauge or less, the rougher the gauge, the higher the weight. It has the disadvantage of increasing sensitivity.

It is also known to manufacture knitted fabrics using spun non-twisted yarns by gluing and laminating water-soluble fibers together, but in this case, after knitting, the water-soluble fibers are dissolved, Even after fulling, some water-soluble woven fabric remains, resulting in poor texture and a tendency to lack weight and bulk, so it is generally not put to practical use in clothing or knitted fabrics. is the current situation.

The present invention aims to eliminate these drawbacks, and to create a lightweight design yarn with a good texture that is rich in quality and quality, and which includes untwisted spun yarn.
The object of the present invention is to provide a design yarn that can be used very effectively, especially in the production of knitted fabrics for clothing, and a method for producing the same.

In the present invention, the above-mentioned problem has been solved by manufacturing Lilian using non-twisted yarn as the core yarn.

That is, the designed yarn of the present invention is a wool fiber with a fineness of 56's to 68's and a core yarn of 30 denier or more, which is made of untwisted yarn with a spinning count of 1710 or less, which is spun from raw cotton with a cut length of 10 cm or less. It is made of lilyyan made of filament yarn or spun yarn.

Such design yarns include wool fibers with a fineness of 56's to 68's,
Lilian is manufactured using filament yarn or spun yarn of 30 denier or more, using a spun yarn made by twisting water-soluble fibers into untwisted yarn with a spinning count of 1710 or less, which is spun from raw cotton of oc m or less, and twisting water-soluble fibers into the core yarn. It can be produced by then dissolving water-soluble fibers.

Merino type wool fibers are mainly used for the raw wool constituting the untwisted yarn that becomes the core yarn, but animal fibers such as lamb, angora, and mohair may also be used as a blend, and the average denier is 5 deniers or less. , other natural and/or chemical fiber raw cotton with a cut length of 10 cm or less may be used.

In the case of spun yarn, the more it is untwisted, the more glossy, soft, lightweight,
Although the bulkiness increases, it is difficult to spin completely without twisting due to the need to maintain yarn strength, and therefore the spinning count is restricted.

In the present invention, since self-spun yarn (1), which has a strength problem when used alone, is used as the core yarn in a state in which it is mixed and twisted with water-soluble fibers such as vinylon 40 denyl, it is possible to stably produce Lilyan. Become.

Lilian can be manufactured by using filament yarn or spun yarn made of chemical fibers or natural fibers with a fineness of 30 deniers or more as processed raw yarn, and the number of threads used in its manufacture is not particularly limited, but it has a fluff effect. In order to obtain a product with excellent bulk and good texture, it is generally preferable to configure the knitting density to be 2 to 6 needles, particularly 2 to 4 needles.

In addition, by using a material with dyeability different from that of the core thread for the Lilyan-processed raw thread, it is also possible to obtain a product with a unique color effect by dyeing.

It is preferable to use Lilyan-processed raw yarn of about 30 to 50 deniers for the purpose of simply obtaining a product with high bulkiness and fluffy effects, but if you are looking for a unique effect between the core yarn and Lilyan yarn. In this case, it is preferable to use something somewhat thicker, about 100 to 300 deniers.

In the present invention, by dissolving the water-soluble fibers after Lilian processing, a bulky, non-twisted spun yarn with good texture and bulkiness made of extremely flexible raw cotton with a fineness of 56°S to 68°S is produced. By using Lilian's knitting structure, a product with stable coverage can be obtained. Therefore, by applying Lilyan processing to a net using thin fibers, the untwisted spun yarn, that is, the core yarn, can be used as a uniquely designed yarn while maintaining its texture and appearance. can be obtained.

In the present invention, after dissolving and removing the water-soluble fibers, it is preferable to apply yarn curling or yarn mink processing to enhance the bulkiness and fluffing effect.

Yumushi Beni - As shown in Table 1, 13 types of design yarns were manufactured by changing the core yarn, the material used for Lilian processing, the knitting density, etc.

The core yarn used in each case was Z124160T/M spun twisted woolen yarn with 40 denier water-soluble vinylon (Slffi230T/M).

JP-A-3 82855 (4)
It can be seen that it can be effectively used in the production of knitted fabrics.

However, in No. 1, the lilyyan processing was carried out with two needles, so the stitches were unstable and it was difficult to obtain a product with commercial value, and in No. 3, the knitting density was too high, so the effect of mink addition was small. However, only products with poor fluffing effect and bulkiness were obtained. Further, even when acrylic fiber was used as the core yarn material at 50χ, the product had poor fluffing effect and bulkiness compared to the case where wool fiber was used at 100χ.

All of the other products have remarkable effects of the present invention, especially No. 2 and No. 4, which have a fluffy effect, a lightweight feel,
A product with a unique texture and appearance such as bulkiness was obtained.

In addition, in No. 4, it is possible to dye the core yarn and the Lilian yarn in different colors, and it is possible to obtain a product with higher fashionability.

No. 5 had bulkiness, flexibility, and a lightweight feel, and was recognized to be sufficiently effective as an accessory ready-made yarn or a hand-knitted ready-made yarn.

Nos. 5.7 and 8 used spun yarns in which animal hair such as mohair, angora, and lamb hair was mixed as the core yarn, but in all cases, N.
o As with 2.4, the lightness and bulkiness unique to non-twisted yarns,
A unique product with excellent flexibility and fluffing effect not found in conventional animal wool yarns was obtained.

No. 9, 10, 12, in order to obtain a hand-knitted yarn, a 1/2 count spun yarn was used as the core yarn, and nylon 30 denier, acrylic 150 denier, and acrylic 150 denier kasuri dyed yarn were used as the lily yarn. This is the one I used and No.
, 10 has a fluffing effect, lightweight, soft, bulky effect, and No. 9 has insufficient fluffing effect, but is lightweight,
It has a bulking effect, a unique effect of wool and acrylic, and a knitted fabric with a better I-look and texture than ever before was obtained.

In No. 12, the fineness of the Lilyan yarn was slightly thick, so no fluffing effect could be expected, but it showed the best texture in terms of light weight and softness.

In addition, in No. 11, a product with a very good texture suitable for machine knitting could be obtained.

In addition, No. 13 uses a spun yarn in which acrylic short fibers are blended with the core yarn in order to reduce weight and obtain the Nolanzi effect, but it has poor curling processability and, as mentioned above, The fluff effect, bulkiness, softness and softness were all unsatisfactory (1), and only a melange effect was obtained.

In addition, Table 1 shows the overall count as Lilian design yarn and shows the appropriate gauge for hand knitting with this design yarn, but in the present invention, the count is 15% more than the appropriate gauge of -C.
It can be seen that a coarse gauge of ~25χ is sufficient.

That is, in the present invention, a product that is 15 to 25x lighter than ordinary yarn can be obtained, and this tendency is particularly strong for yarns with finer core yarns or yarns blended with animal hair. In this case, of course, the Lilian processing material is also 30
~50 denier is most effective.

Furthermore, it can be seen that when the raw yarn for Lilyan has a denier of 100 denier or more, the fluffing effect itself is significantly reduced.

As described above, the designed yarn according to the present invention is manufactured by processing the spun yarn, which is made by twisting untwisted yarn spun by wool spinning and water-soluble fibers, as a core yarn, and then melting the water-soluble fibers. In addition to special effects that cannot be achieved with designed yarns made of spun yarn, such as weight reduction and bulkiness, the product also has a super fluffy effect due to woolen yarn, a soft texture, and a firm feel. In addition, after dissolving and removing the water-soluble fibers, by subjecting the yarn to m-fila or yarn mink processing, the fluffy portions become entwined with each other, thereby improving coverage and heat retention.

Furthermore, even if the core yarn is a non-twisted yarn, it is held by Lilian net, resulting in a very stable design yarn with very little fluff falling off.
