Description

Detailed Description of the Invention c Technical Field of the Invention The present invention relates to a composite spun yarn comprising filament yarn and stable fiber. More specifically, it relates to a specific composite spun yarn in which a filament yarn is arranged in the inner layer and a blended stable fiber of hemp and polyester is arranged in the outer layer.

[Prior art and its problems]

Traditionally, hemp 100 yarn and hemp blend yarn have been preferred for spring and summer. In addition, in order to achieve the stiffness and coolness of hemp, there are filament yarns with some fibers fused during the temporary twisting process and strong cotton yarns, but this can be achieved by adding a rough texture. It is no exaggeration to say that the moisture absorbing ability and unique luster of linen (ramie) are at an unsatisfactory level. In addition, approaches such as imparting a crisp feel to spun yarns by using irregular cross sections have been seen, but they suffer from the same problems as the filament yarns. However, the biggest advantage of the spinning process is that it allows the blending of natural fibers and synthetic fibers.99 A blend of real hemp and hemp-like synthetic fibers is common. In this case, the blending rate of expensive hemp is set as low as possible, and the texture is similar to that of a hemp blend.

The reality is that they are trying to express dignity.

However, since conventional spinning techniques generally only perform uniform blending, the blending method can only produce the effect of the blending ratio. Furthermore, since ramie fibers generally have a thick single fiber denier, yarn unevenness is large, and furthermore, yarn breakage occurs frequently, making efficient production difficult in many cases.

[Purpose of the present invention]

The present invention aims to solve the above-mentioned drawbacks, and the purpose is to create a hemp material that exhibits an effect greater than the blending ratio of hemp, and that has improved firmness, stiffness, and evenness as a thread. To provide a composite spun yarn in which staple fibers containing hemp are arranged in the outer layer of a blended composite spun yarn, and staple fibers containing hemp are arranged in the core part.

[Configuration of the present invention]

The present invention consists of the following configuration.

"The filament component is arranged in the innermost layer of the composite yarn cross section,
In a composite spun yarn in which staple fibers containing hemp are present in the outer layer, polyester staple fibers with an irregular cross section and titanium oxide content of 0.2% by weight or less are present in the outer layer, and the twist coefficient of the composite yarn as a whole is -K is 6
A linen blend composite spun yarn characterized by having a yarn weight of 0 to 150.

” In the present invention, hemp refers to flax, ramie, jute, and cannabis.

Manila hemp, cyza hemp, etc. may be produced in any region, such as the Philippines or China, and there are no restrictions on the scouring conditions. In addition, in the present invention, it is extremely important that the amount of titanium oxide in fibers other than hemp fibers is less than 0.2% by weight in order to emphasize gloss. The amount of titanium is 0
．． If the value exceeds 2% by weight, it will not give a glossy and luxurious feel. Also, the purpose of the irregular cross section is to emphasize the crispness. It goes without saying that staples other than the above-mentioned fibers (for example, fibers made of cationic dyeable polymers) may be used in combination for the purpose of imparting a different color effect (marbling).

Further, the fiber length of the staples constituting the yarn may be appropriately used within the range of 20 to 180 mm in terms of average fiber length.

On the other hand, the filament yarn has a torque denier of 10~
Preferably, it is a 200 denier monofilament or multifilament. This is to fully demonstrate performance such as crispness and firmness.

From a practical point of view, it is preferable that the single fiber denier constituting the filament yarn is about 1.5 to 60 denier.

In the present invention, the preferable yarn count of the composite yarn is approximately 1/100 to 1/20 of practicality (9) and functionality (4).

Furthermore, by using a temporary twist thread as a filament component of the present invention, the temporary twist process not only changes the shrinkage performance but also irregularly changes the cross-sectional shape. The cross-sectional shape can give a crisp feel when compared to at least a round cross-section. Furthermore, even straight yarns having a simple irregular cross-section can be given a sharp taste, although they are slightly different from the temporary twisting process described above. Other irregularly shaped cross sections blend well with staple fibers and do not cause peeling. Furthermore, it is extremely easy to express the linen texture with a specially processed yarn in which some of the fibers are partially fused during temporary twisting.

The filament component of the present invention may also be a specially twisted yarn that is alternately twisted in the yarn axis direction.

In the present invention, the twist coefficient K of the composite yarn as a whole is 60~
A range of 150 is necessary to maintain the integrity and texture of the staple component and filament component. More preferably, K is 80-135. Twist coefficient K is 6
If it is less than 0, it is not preferable because the thread has poor tightness, and when made into a fabric, the pile pill performance deteriorates and the feel also deteriorates. If the number exceeds 150, the stiffness of the single yarn becomes too strong and the passability in the subsequent process becomes extremely poor, which is not preferable.

The above twist coefficient is determined as follows.

T: 1Tf7;r T: Number of twists per 1m: Twisting coefficient Nm: metric count The composite yarn of the present invention can also be used by twisting a plurality of yarns such as twin yarns, triple twists, etc. Especially when using double yarn, it can be made into a high-quality fabric. In this case, the thread count suitable for use is 2/30 to 2/30.
The twist coefficient is preferably about 85 to 120% of the single yarn.

One embodiment for obtaining the yarn of the present invention will be explained in detail with reference to the drawings. FIG. 1 shows an example of its manufacturing process. First, the roving 1 made of linen blend is connected to the trumpet guide 2. Back roller 3. The fleece 1' is fed out through the apron 4 from the nip point between the front bottom 5 and the large diameter portion 6a of the front top roller 6. On the other hand, the filament component 7 is fed to a supply roller 9 via a tension adjusting device 8 .

Next, the yarn is guided through the gap between the small diameter part 6b of the front top roller B and the front bottom shaft 5, and the yarn is introduced into the fleece 1.
/ and is combined with a ring spinning machine to focus the actual material. Preferably, the filaments are merged near the twisting point of the fleece 1'.

In the figure, snail guide 11. Travelers 12° and 13 are shown. The velocity relationship when the two components are combined is controlled by feed control so that the velocity of the staple component is in the relationship of Vs, and the typical product has a good Vs VF of 070 to 0.99, more preferably 0.90 to 0.98. V
s = VF.

Figure 2 is an enlarged view of the combined and twisted part in Figure 1.
FIG. Large diameter portion 6 of front top roller 6
The shapes of the small diameter portion 6b and the shape of the fleece 1' and the filament component 7 are clearly visible. In the figure, the union distance of the two components is an important factor for stabilizing the verb, and is preferably set to 10 or less.

FIG. 3 shows a hemp blended composite spun yarn 10 of the present invention, in which filament components 7 are arranged in the innermost layer of the yarn 10, and staples 1 containing at least hemp are arranged to surround the outer periphery of the crease. It shows the form.

[Effects of the present invention]

Since the composite yarn of the present invention has a structure as shown in Fig. 6,
The filament component of the core improves the firmness, stiffness, and strength that is desirable for the texture.

It's almost like a louse.

In addition, the outer layer component is a blend of polyester staple, which has an irregular cross section that is very similar to ramie in appearance, gloss, etc., and contains less titanium oxide.

This is a comprehensive approximation to Lamy.

For the above reasons, for example, even if 7 to 8 weight units of Ramie are present, the actual feeling is equivalent to that of about 20 weight units, which is a remarkable effect.

In addition, because of the presence of ramie, it has excellent moisture absorption and sweat absorption properties, making it extremely comfortable to wear. Furthermore, since it contains a large amount of polyester, it also has wash-and-air properties and exhibits an excellent effect in one function.

This will be explained below using examples.

Example 1 50D-24Fil temporary twisted yarn was used as the filament component, while ramie ion was used as the stable component.
Regular bright type polyester (titanium oxide 0)
A spinning yarn of 2152 was spun using rovings consisting of 3dx89v45% of triangular cross section and 4x89v45% of cationic dyeable polyester round cross section. The twist coefficient was set to 160. Further, the supply speed relationship of the two components was set as 095VB == Vp. Turn the single yarn down to 1
Double yarn processing with 00 reversing was carried out. The resulting yarn was woven.

We prototyped four types of weave: plain weave, 2/2 twill, 4/2 torn diagonal weave, and chiss weave.All of the products had good threads, a crisp feel, and excellent resilience. It became. Among these products, some products dyed in unique colors aiming at marbling effects have also become products with excellent aesthetics. Furthermore, the anti-build properties of the obtained products were grade 4-5 after 10 hours of ICI method, and it was found that there was no problem in practical use. In addition, the wrinkle resistance was compared with 100% Lamy.

This improved the excessive wrinkles that were considered to be the biggest drawback of Lamy 100qb. The linen blend composite spun yarn of the present invention was extremely excellent in terms of process conditions in the commercialization of this example.

Example 2 100-24 temporary twist thread as filament component.

Staple component: 20% hemp (ramie), regular bright type (titanium oxide 0% by weight) U-shaped cross section 3
Use dx89ma 80% staples.

1/26. K=110. Further, the supply speed relationship between the two components was set to 0.96VB =VF. The obtained yarn was made into a single yarn fabric. Three types of weave were prototyped: flat, 2λ2 twill, and Hachisu weave. Although the resulting product had a slightly less crisp feel than the product exemplified in Example 01.

For comparison, when compared with a fabric using 100 staples having the same specifications as above, it was clearly superior in crispness and quality. Excellent in anti-building properties
(IC construction method, 10 hours) and a level that does not pose any practical problems was obtained. Furthermore, it was also good in wrinkle resistance.

Example 6 A 50D-24Fi1 temporarily twisted and fused yarn was used as the filament component, while the staple components were 10% hemp (short-cut linen product), 25% cotton (cotton), and pill-resistant polyester raw cotton (titanium oxide 018% by weight). %) 1.3
a x68 mI] l165 To.

The two components were fed and combined in a relationship of 0.95Vs=vp. The count was Nec = 32Sβ, and the coefficient was 2. The obtained yarn was subjected to a 16-gauge weft knitting machine for flat knitting and 1×1 ribbing. The resulting knitted fabric had a crisp and refreshing feel. In terms of reed building resistance, the IC construction method achieved grade 4 for 5 hours.
