Description

[Detailed Description of the Invention] F. Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a heterochromatic spunlike textured yarn and a method for applying it, more specifically, it relates to a spunlike yarn with a spun-like texture and a dyeing method. The present invention relates to a heterochromatic spunlike processed yarn that can provide a dull heather effect and a method for producing the same.

(Prior art) Heterochromic spun-like processed yarn is capable of combining a spun yarn-like texture with a deep-bedded heather effect through dyeing.
◇ Such spun-like processed yarn has been proposed in Japanese Patent Publication No. 57-21526, which has a core made of polyester multifilament that is undyable to ionic %: #, and a polyester multifilament that is undyable to Vc ionic dye as a core. The polyester multifilament and the polyester multifilament dyeable with mA dye are twisted alternately as the details, and each filament is mixed and intertwined with each other at the boundary between the core and the details. It is a two-layer structure yarn that forms the section.

Moreover, the Cocoon-like heterochromatic polyester spa/like processed yarn is a processed yarn that has both a spun-like effect and a good heather effect.

It is used for removable applications that require aesthetics, as well as for interior applications such as curtains.

By the way, recently, in these clothing and indoor uses, fabrics with a softer texture, a fine heather effect, and a light color heather, compared to the fabrics obtained using the above-mentioned unique polyester spunlike processed yarn, have been developed. There is an increasing demand for cloth hangings that exhibit both texture and texture, and there is a need for unique spunlike processed yarns that can produce such fabrics.

(Objective of the Invention) An object of the present invention is to provide a unique spunlike processed yarn that can be used to hang a cloth that exhibits both an extremely soft texture and a glazed heather effect, and a method for producing the same.

(Kiri, @) The present inventors believe that in order to achieve the above-mentioned objective, it is effective to add polyamide filaments, which have different physical properties such as dyeability, from polyester filaments to conventional heterochromatic polyester spunlike threads. As a result of considering whether it is possible, I found that it has an extremely soft and fine heather effect1
The present invention has achieved a heterochromatic spunlike processed yarn that can be filtered (first invention) and a method for producing the same (second invention).

In other words, the ml invention of the present invention is the core structure! around the filament to be dyed with J! In two-layer m yarn making, the filaments are wound in an alternating strand shape as a sheath part, and each filament is mixed and intertwined with each other at the boundary between the core part and the details to form a knot part. The layered yarn is composed of at least three types of filaments: a polyester filament that is undyable with ionic dyes, a polyester filament that is dyeable with Tx injection dyes, and a polyamide filament that is dyeable with acid dyes. , the filaments mainly constituting the sheath are selected from the filament groups described above, and at least one type of filament is selected from the above filament group; It is a unique spun-like processed yarn characterized by different gender.

Further, a second aspect of the present invention is a multifilament having different dyeability, and a difference in elongation between a multifilament having an elongation of 100 to 250X and the multifilament having an elongation of 2509 or more. 80% or more of the multifilament is mixed, mixed and interlaced by YL turbulence treatment, and then simultaneously stretched and false-twisted at a stretching ratio of 1.2 or more*m to avoid differences in dyeability. As the multifilament, at least a class 3a multifilament, such as a polyester multifilament that is undyable with ionic dyes, a polyester multifilament that is dyeable with salt-based dyes, and a polyamide multifilament that is dyeable with acid dyes, is used. At that time, this is a method for producing a heterochromatic spunlike processed yarn, which comprises using at least class 2a multifilament from the multifilament group as a high elongation multifilament and as other filaments, respectively. .

The processed yarn of the present invention is a two-layer structured yarn shown in Figure $1,
Around a filament constituting the core, filaments having different dyeability from the filament are wound in an alternating strand shape as a sheath, and each filament is mixed and intertwined with each other at the boundary between the core and the details. It is a unique spun-like processed yarn with intertwined parts.

Figure 1 shows 11 of the unique spun life carbon U yarns of the present invention.
It is a one side view, (a) shows the core part of the filament Φ, and (b) shows the sheath part of the filament.

The two-layer structure yarn shown in Figure 1 has a core (core yarn) made up of filaments (bi) and a filament (i) made of filaments (→
There is virtually no so-called helical winding part in which the sheath part (wound thread) is completely wrapped one or more times (the winding thread as a whole is almost continuously alternately reversed). , S, and Z twist directions are wound less than 360' with respect to the core yarn.Moreover, a part of the filament (B) constituting the wound yarn L is
Since the core thread is intertwined with a part of the constituent filaments (A), the winding is incomplete due to alternating rotation, and there is a high degree of σ bond between the core thread and the winding thread.

Oneness arises. Therefore, such a two-layer yarn can exhibit spun-like M4it.

It is necessary to give a more spun-like texture to a part of the support (even if a part of the wound yarn is cut and the free gIA is released into a fluffy shape protruding from the yarn surface, other gs structures with one fluff will be Since it is intertwined with the core yarn, it is stable and will not fall off due to external forces such as fluffing.

In the present invention, such a two-layer structure yarn is used.

At least three polyester filaments that are undyable with ionic dyes, polyester filaments that are dyeable with basic dyes, and polyamide filaments that are dyeable with acid dyes.
It is composed of filaments of class 8, in which case it is a filament (b) consisting mainly of a sheath part (11I) or a filament of at least class zaI selected from the above filament group, and on the other hand, at least a filament of class zaI consisting mainly of a core part (b). It is important that the filaments of this type have different dyeability from the filaments of the above two types.

Here, the two-layer structure yarn shown in JP-A-57-21526, i.e., the filaments mainly constituting 1IVs, are polynisdel filaments that are undyable to ionic dyes and polynisdel filaments that are dyeable to basic dyes. The two-layer structure yarn, which is a polyester filament and whose filament mainly constituting the core is a polyester filament that is undyable to ionic dyes, is compared to the two-layer structure yarn of the present invention.

The texture becomes hard and exhibits a rough heather effect.

The two-layered yarn of the present invention is composed of 3AL type filaments: a polyester filament that is undyable with ionic dyes, a polyester filament that is dyeable with salt-crystalline dyes, and a polyamide filament that is dyeable with acid dyes. In this case, there are mainly two types of filaments, the filament constituting the sheath part and the filament group, and on the other hand,
It is preferable to use a two-layer structure yarn in which the filaments mainly having the core W6 *g are type I filaments having different dyeability from the above two types of filaments.

The filaments that mainly constitute the core of a two-layered yarn are two or more types of filaments that have different dyeability, or the filaments that make up the sheath (i-i) have different dyeability. If the above filament is used, the heathering effect of the two-layered yarn becomes excessively strong, and the heathered tone of the final fabric tends to become too light.

In such a two-layered yarn, it is preferable that at least 2a type filaments, which mainly constitute 11 parts, are mixed and interlaced in a random manner to obtain a good heathering effect.

Further, the filament constituting the core part may mainly contain a part of the filament constituting the sheath part, or the filament constituting the sheath part may contain a part of the filament constituting the core part as soil. It is preferable that the elongation of the main filament is 1υ〇9 or more. .

Furthermore, some or all of the filaments constituting the two-layered yarn may differ in filament denier filament cross-sectional shape, dissipating agent content, and the like.

The filament denier of the two-layered yarn of the present invention is 9! desired color tone JP
The filament (4) that mainly constitutes the core should be selected as appropriate depending on the final use, but the filament (4) that mainly constitutes the core should be
Filament 03) (C
) to be thinner than 3 tenier provides bulkiness when made into a woven or knitted fabric.

It is more preferable in terms of texture, texture, and elasticity.

The filament constituting the raw core S, and the filament (a) mainly constituting the details (C1) If the respective constituents of C1 satisfy the following conditions, dyeing will combine the uniqueness with deep ribs and a good heather effect. It is preferable that it can be presented as such.

(At: (B): (Q=30%~70:]〇9~50
%: 10X-509 + (Tun + 1) = 100X Note 1: In the two-layer structure yarn of the present invention, if the filament that mainly constitutes the core or a part of it is a filament made of polybutylene terephthalate, it can be used as a stretch material. It is preferable because it has a spun-like textured yarn with 0 shoulders.

To manufacture the spunlike processed yarn of the present invention,
Multifilaments with a difference in elongation of 1 are combined, mixed and intertwined by a turbulent air flow, and then simultaneously stretched and subjected to a friction false twisting process at the time of binding, at least 3A16 with different dyeability
It is important to use one multifiller.

As multifilaments of at least 3AL types with different dyeability, polyester multifilaments that are undyable with ionic dyes, polyester multifilaments that are dyeable with salt-crystalline dyes, and polyamide multifilaments that are dyeable with acid dyes are used. Using a filament, at least two kinds of multifilaments of the multifilament group are made into multifilaments with elongation of kA, and multifilaments of at least class LA, which have different dyeability from the two kinds of multifilaments, are made. It is important to use different elongation multifilaments.

In the manufacturing method of the present invention, as shown in the second factor,
The heather of the two-layered yarn can be obtained by using a multifilament of L& class as a low elongation multifilament and using the above multifilament and two types of multifilaments having different dyeability as a high elongation multifilament. This is preferable because it does not make the effect too thin or make the heathered tone of the final fabric too pale.

FIG. 2 is a route map showing one embodiment of the present invention.

In Figure 2, the difference in elongation between multifilament (1) with an elongation of [100 to 2509] and multifilament 11+ with an elongation of 250X or more is 80% or more (preferably 10
0 meter◇ or more) multi-like men) +21 +31 and guide (combined threads with 41, tension l!14 adjustment device (5),
The fibers are fed through a pair of feed rollers (6) and (6') to an air turbulent flow nozzle (7) for mixing and entangling to form an entangled yarn. Next, this intertwined yarn is passed through a pair of first delivery rollers +
81 (8') to the stretching false twisting zone, L-tar (9), 3-axis long disc type external friction false twisting tool α,
The processed yarn obtained through a pair of second delivery rollers (11) (11') is wound up as cheese (13) by a winder (12).

The stretching ratio at this time, that is, the first telly roller t81
(8') and second delivery roller (11) (11'
), the drawing ratio between the
Double it.

Here, if the elongation of the multifilament (1) is less than 100, yarn breakage will occur frequently during the draw false twisting process at a draw ratio of 1.2@ or more, and the elongation of the multifilament (1) will be less than 250. The multifilament that becomes the sheath (
2) Since the looseness of (3) becomes poor, the spun-like effect of the processed yarn subjected to Vch is reduced.

Also, the elongation of multifilament +2 + 131 or 25
If the elongation difference from 09 or multifilament +11 is less than 80%, multifilament 12+
The winding of 131 becomes poor, and a good alternately twisted two-layer structure yarn cannot be obtained.

Adjust the position of the air agitation nozzle (7) to the second delivery roller (11) (11') and the winder (12).
If this is done between the two, the entanglement between the winding yarn and the core yarn is small, so that the winding side becomes taut during processing, making it impossible to obtain a good spun-like processed yarn. In this case, the deformation treatment is preferably carried out so that the degree of entanglement of the threads is 20 to 80 threads/shoulder. If the degree of entanglement is less than 20 strands/way, the core yarn (a) and the wrapped yarn (b) are likely to separate in the processed yarn. There is a tendency for the heathering effect to deteriorate due to insufficient blending of filaments of different filaments.If the degree of entanglement exceeds 80 wires/m, the yarn physical properties tend to deteriorate rapidly.

The "degree of confounding" referred to here is defined in U.S. Patent No. 2.98.
5.991 Crying Mgl! This is the value n measured by the hook-drop method described in No. 3,110,151 No. 1q, 4441.

In the manufacturing method shown in FIG. 2, low elongation multifilament [multifilament in] and U high elongation multifilament [multifilament! 2113
1) When the combinations shown in Table I are used,
It is preferable to obtain a two-layer structure yarn with the texture and/or function shown in Table 1.

Spinning speed 2500 m1 minute or more, especially 3000 to 400
It is preferable to use 4Th oriented yarn obtained by melt spinning at 0 m/min.
Spinning speed of 500 m/min or more, especially 1000 to 2000 m
It is preferable to use a multifilament obtained by melt spinning at Φ/min.

Further, as the all-air stirring turbulent flow nozzle shown in FIG. 2, a generally used nozzle for interlace processing is suitable, but a 1-taslan nozzle is also applicable. Further, after being entangled with a turbulent air trap, it may be rolled up once, or it may be subjected to simultaneous stretching and temporary combustion without winding up. The heater temperature during this false twisting process is 130 to 200°C.
, etc., it is preferable to set the temperature to 130 to 180°C. If the heater temperature exceeds 200° C., the processed yarn or carpet material obtained tends to become rough, and if the heater temperature exceeds 130° C., streaks tend to occur. As a single-rubbing false twister, it can falsely twist the yarn and at the same time have a feeding action.

A three-axis long disc type circumscribed friction false twister as shown in FIG. 2, which can be twisted, is suitable.

At this time, in the 3-axis step-task type circumscribed friction false twisting tool,
A winding yarn in which a rough friction disk is provided on the yarn entry side and the yarn being processed is brought into contact with the disk to form a sheath, as described in the specification and drawings of No. 54-fi 536. (
It is also possible to cut a part of the filament (b) and raise it to make a spun-like processed yarn having a fluff 1.

In addition, in the present invention, "polyester that is undyable with ionic dyes" refers to polyethylene terephthalate or ionic dye Kl! Polyester or polybutylene terephthalate containing an unconventional third component (for example, isophthalate, propylene glycol, etc.), which can be substantially dyed with ionic dyes such as acid dyes and basic dyes. A general term for polyesters that cannot be dyed, and "polyesters that are dyeable with basic dyes" include polyesters that contain molecules that are dyeable with basic dyes (e.g., sulfonate groups) or polyesters that are dyeable with basic dyes. A general term for polyesters that are blended with additives and that are dyeable with basic dyes. Polyethylene terephthalate containing about 0.5 to 10 moles of sodium is preferred.

In addition, "polyamide dyeable with acid dyes" is a general term for synthetic polyamides that are dyeable with Wl dyes and have a substantially edge-like shape with amide bonds, and are made up of nylon 6%. ,
Nylon 66 is preferred.

(Function) In the present invention, the main filaments constituting the sheath part of the two-layer yarn are filaments having different dyeability from each other, and the core part is composed of M, and the slippery filament is the sheath S. Since the filament has a different dyeing property from the filaments that mainly constitute the filament, the two-layer structure yarn known in the publication No. 57-21526, that is, the main filament that constitutes the sheath part, is not dyed by ionic dyes. Compared to the two-layer yarn, which is a polyester filament dyeable to basic dyes and a polyester filament dyeable to basic dyes, the main filament constituting the core is a polyester filament that is not dyeable to ionic dyes. Can exhibit a kana berry effect.

Moreover, in the two-layered yarn of the present invention, since the sheath portion or the core portion is made of polyamide filament having different dyeability and other physical properties from polyester filament, the above %iMl!
It can exhibit a softer texture than the two-layered yarn shown in the introduction.

Therefore, the fabric obtained using the heterochromatic spunlike yarn of the present invention has both a soft feel and a voluminous feel, and the dyeing vkK can exhibit a fine heather I11.

Further, the fabric obtained using the processed yarn of the present invention can be made to have a plain tone, a two-color heathered tone, or a three-color heathered tone, depending on the selection of dyes.

(Effects of the Invention) The heterochromatic spunlike processed yarn of the present invention can be used for autumn/winter clothing and interior applications such as curtains.
