Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to a specially processed yarn with a design yarn waste. More specifically, the present invention relates to a special textured yarn with a design yarn formed by fluid agitation of slab yarns and flat yarns in which both the ground portion and the slab portion have a twisted structure, and the twist density of the slab portion is higher than that of the gland portion.

(Prior art) Methods for producing slub yarns made of multifilament yarns of synthetic fibers include those obtained using false twisting (Japanese Patent Publication No. 59-35147, Japanese Patent Application Laid-open No. 50-20062);
Obtained by fluid disturbance treatment (Special Publication Publication No. 48-29
No. 507, No. 47-15547) A method using a design twisting machine is known. Among these, the slab yarn obtained by the former false twisting process has a twisted structure in both the slab part and the ground part, and the system as a whole is limited to the texture of strongly twisted yarn. The current situation is that we are not necessarily able to respond to the current situation. However, such slub yarns can not only be obtained at high speed using a general-purpose machine called a false twisting machine, but also have superior texture compared to flat yarns in various respects, and their usefulness cannot be dismissed.

(Object of the Invention) The object of the present invention is to diversify the texture of the above-mentioned slub yarn, which has been limited in terms of texture and use, from woolen to raw silk (Raws i I k) 1m, as well as worsted yarn. The purpose of the present invention is to provide a specially processed yarn with a design yarn that can achieve a texture that matches the desired texture.

(Structure of the Invention) According to the present invention, the composite yarn is a composite yarn in which both the ground portion and the slab portion have a twisted structure, and the slab yarn and the flat yarn, which have a higher twist density in the slab portion than the gland portion, are fluid-disturbed. (a) the slab portion is substantially aligned with the flat yarn, while (b) the ground portion is a filament that is engaged with the flat yarn and forms a minute loop with the filaments forming the ground portion. (c) The slab portion is provided with a specially processed yarn having a minute loop, and (c) the slab portion is fixed in position by the joining portions (b) at both ends thereof.

The attached drawings show side views of the specially processed yarn of the present invention, in which (a) shows the designed part where the slab part 1 of the slab yarn and the flat yarn 3 are substantially aligned; (b)
is a ground yarn portion where the ground portion 2 of the slub yarn and the flat yarn 3 are in a mating state. Further, 4 is a loop.

Here, the conjugated state refers to a state in which the ground part of the slab yarn and the flat yarn are mainly mixed/entangled, a state in which they are wrapped around each other, or a state in which one is used as a core yarn and the other is wound around it. It refers to the state of being followed.

In the present invention, the mixed fiber/entangled state is usually referred to as the conjugated state, but the latter twisted state may also be mixed depending on the processing conditions. Such a textured yarn can be obtained by feeding the above-mentioned soft yarn and flat yarn together under overfeed to a fluid disturbance area, such as a taslan nozzle.

In this case, it is important to increase the feed rate of the former by 3-18%, the latter by 10-50%, and the latter by 3-40% more than the former. Further, the fluid pressure in this case is 2.5-9.0 KG/cm 2NrllfiI.

Here, as the yarn forming the textured yarn of the present invention, thermoplastic filament yarn (polyester, polyamide, acetate) is preferably used because in the case of slub yarn, false twisting is applied in advance. In this case, the core yarn of the slub yarn is a filament yarn with a single yarn de of 1 to 3 de and a total denier of 50 to 200 de.
In addition, the wrapped yarn (effect) has a single yarn de of 0.01~
3 de, and a filament yarn having a total denier of 50 to 200 de is used. On the other hand, the flat yarn may be any of the above thermoplastic filament yarns, recycled fiber yarns, etc. as long as it is a continuous filament yarn. As for the thickness, a filament yarn having a single yarn de of 0.01 to 3 de and a t-tal denier of 50 to 200 de is used. Among these, in particular, if a yarn with a single yarn de of 0.5 or less and a total de of 75 or more is used, the loop will be extremely soft and a soft-touch textured yarn can be obtained. Note that not only drawn yarn but also semi-drawn yarn (POY) can be used as the wrapped yarn and flat yarn.

(Operations and Effects of the Invention) According to the present invention, by adjusting the twist coefficient of the slub yarn, it is possible to express a texture ranging from a woolen texture to a raw silk texture to a worsted texture. For example, if the twist coefficient A during false twisting of the slub yarn is set to 0°01g, 0.25 or less, and the feed amount is increased for both the flat yarn and the flat yarn, a woolen texture will be obtained;
In addition, when the feed amount is reduced, a worsted texture is obtained. In addition, the amount of overfeed is reduced, and
When making the above A larger than 0.3 (the upper limit is 0.65
(Hodomaro), the twisting effect takes priority and the texture is refreshing.

In addition, raw silk is characterized by (a) naturally varying thickness, (b) thick and long slabs, and (c) light, soft, yet firm texture. In this regard, according to the present invention, the above point (a) is achieved by combining the rectangular slab with the flat yarn, resulting in a mild slab shape, and the point (b) is achieved by using a large slab. Point (c) is achieved by the coexistence of the twisted yarn structure and the loop.

Incidentally, it is assumed that the A is expressed by the following formula.

A=Number of false twists
/32500 Also, when the loops in part a are made into a woven or knitted fabric, they create a spun-like texture with a sense of swelling and warmth, and when finishing processing such as shirring is applied, depending on the size and number of the original loops, it creates a worsted-like texture. It contributes to the realization of a variety of textures, from wool to wool. However, the degree of entanglement, the number of loops, and the size of the loops in part (b) may be adjusted by combining various requirements such as the flow rate of the overfeed m1 fluid of the flat yarn and the fluid pressure, the number of twists of the ground part of the slab yarn, and the length. . Of course, loops occur not only in the (a) section but also in the ground yarn section (b), which increases the swell of the system as a whole (if the feed rate of the flat yarn is high).

Here, the point of the present invention is that the ground part of the slub yarn, which has the texture of a highly twisted yarn, is untwisted by fluid disturbance, causing a feeling of swelling, and at the same time, this part is combined with the flat yarn and loops are created. It changes the texture over a wide range.

One of the features of the present invention is that part (b) is conjugated, so that the slab part is fixed and the handling of the entire system is improved, especially in J1
An example of this is that the reproduction of slabs in knitted fabrics is ensured. That is, since the slub yarn obtained by false twisting has a shape in which the sheath yarn is simply wrapped around the core yarn, the slub portion tends to slide along the core yarn, making the shape extremely unstable. . However, in the case of the present invention, since the ground portions at both ends of the slab portion are engaged with the flat yarn, the slab portion is fixed and the subsequent handling properties are further improved.

Another effect of the present invention is that a textured yarn exhibiting a unique color effect that has not been realized hitherto can be obtained. In other words, in the case of woven and knitted fabrics using single threads of slub yarn, dyeing them would only result in monochromatic dyed fabrics, but in the case of the present invention, the dyeability of the wrapped yarns that make up slub yarns is the same as that of flat yarns. By making them different, the dyeing effect of the slab part which is aligned with the flat yarn will appear as it is, while the ground part of the slab yarn part will be mixed and intertwined with the flat yarn, so it will have an intermediate color with the wrapped yarn. Creates a color contrast effect.

(Example) The process (
Using a single slub yarn (without using guides 7, 8, and 9), a single slub yarn and a flat yarn were processed under the conditions shown in the following table to produce a specially processed yarn with a design yarn appearance of the present invention. next. The warp of the obtained processed yarn was processed under the conditions shown in the table below to produce a specially processed yarn with a design yarn appearance of the present invention. next. The obtained processed yarn is used as warp and weft, each with a cover factor of 8.
400, and a 2/2 twill fabric was produced.

Here, the cover factor B is: B=thread density (books/inches)
It is expressed as x e11-(d e is the denier of the yarn).

As is clear from the table, the fabric of Example 1, 3.6°7 exhibited a fluffy and warm woolen texture, while the fabric of Example 4.81 exhibited a worsted texture. In addition, Example 3,
In the fabric of No. 4.6, by dyeing only the effect yarn black, a so-called black nep yarn in which the black color of the slab part stood out was obtained. Furthermore, in the fabrics of Examples 7 and 8, the effect yarn in the slab portion was dyed on one side by single-sided dyeing only the yarn or flat yarn, and a so-called white nep yarn that stood out in white was obtained.

Furthermore, in Examples 2 and 5, the twisted structure of the slub yarn gave a crunchy feel, and a spun-like texture with a refreshing feel was obtained.
