Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a slab-like molding yarn and a raised fabric. More specifically, the present invention relates to a slab-like molding yarn and a raised fabric in which thick and thin irregularities are actively mixed in the length direction.

[Prior Art] Conventionally, molle yarn has luster, texture, touch, bulkiness, etc. due to its three-dimensional structure, and excellent knitted fabrics have been manufactured and sold. However, due to the manufacturing method of molle yarn, the length of the napped fibers is uniform, and knitted fabrics using molle yarn have the disadvantage of no surface change and lack of three-dimensional appearance.

In order to improve this problem, a proposal has been made to change the length of the nap by changing the position of the cutting blade when manufacturing molle yarn, as seen in JP-A No. 56-20629.

[Problems to be Solved by the Invention] However, although the length of the napped fibers produced by this method changes, the number of implanted napped fibers (density) does not change, and only a monotonous slab-like moulding yarn can be obtained. First, the raised naps of knitted fabric products are not crushed or bent, so there is no three-dimensional effect, and the device is complicated, which is not common.

[Means for Solving the Problems] The slab-like mall yarn of the present invention has the following configuration in order to solve the above problems. That is, the napped fiber is a molle yarn made of spun yarn, and the thickness of the fine yarn portion is 15% to -90% of the average thickness of the molle yarn.
The thickness of the thick yarn portion is in the range of +50% to +900%, the length of the thick yarn portion is 5 to 1000M, and it is a slab-like mall yarn that is mixed randomly.

Moreover, the raised fabric of the present invention has the following configuration in order to solve the above problems. That is, the napped fiber is a molle yarn made of spun yarn, and the thickness of the fine yarn portion is 15% to -90% of the average thickness of the molle yarn.
A raised fabric characterized by using slab-like malle yarns whose thick yarn portions have a thickness in the range of +50% to +900%, whose thick yarn portions have a length of 5 to 1000 m, and are mixed randomly. be.

In the present invention, the molle yarn is composed of napped fibers sandwiched and held by two or more ground yarns, and several low-melting point fibers to fix the ground yarns and napped fibers, and the surface is covered with napped fibers. It is a raised filament.

In the present invention, the spun yarn that makes the napped fibers is hereinafter referred to as filament yarn.

A detailed explanation will be given below with reference to the drawings.

FIG. 1 shows an example of a slab-like mall yarn according to the present invention, in which 1 is a napped fiber, 2 is a ground yarn, and 3 is a low melting point fiber for fixing the napped fiber. 4 indicates the shape of the thin yarn portion, and 5 indicates the shape of the thick yarn portion, and the slab-like mole yarn of the present invention has slab-like portions having various lengths, thicknesses, and densities mixed randomly in the yarn length direction. It is something.

Such thick, thin and random slab-like mole yarns can be obtained by appropriately changing the thickness and length of the spun yarns that become the napped fibers.

FIG. 2 shows a schematic diagram of a general molding manufacturing apparatus as disclosed in, for example, Japanese Unexamined Patent Publication No. 53-6642. For the mall thread, the filament is wound from the disk (2) called the flyer around the guide part (a) (also called a gauge) at a constant rotation, and then passed to the cutter part (c) while being lightly pinched by the left and right rollers (b). It is fed in, gripped by the ground yarn and low-melting point fibers, and then twisted to become a mall yarn. In this case, when the thick yarn part of the spun yarn constituting the filament is supplied and enters the guide guide, the circumference length wrapped around the guide increases, and the filament cut by the cutter becomes longer than the normal part. On the other hand, when the fine thread portion is supplied, the length of the napped fibers wound around the guide portion becomes shorter, and the length of the napped fibers becomes shorter.

In addition, since it is wound at a constant rotation, when the thick yarn part of the spun yarn is supplied, the thick yarn part has a large number of fibers, so the napped fibers become longer and the napped fiber density also increases, making it difficult to see through. This creates a strong, thick thread that is not easily crushed or bent.

In addition, the fine yarn portion has a short nap fiber length and a low nap density. In this way, slab-like mole yarns with different napped lengths and napped densities can be obtained, and by appropriately mixing the thick/fine ratio and thick/thin length of the spun yarns constituting the napped fibers, the slab-like mole yarns of the present invention can be obtained. can get.

The nap density is influenced by the count and fineness of the spun yarn, and the number of guide windings of the filament, that is, the feeding speed of the filament.

For example, use 3 denier 100%, metric count 1/1
0 spun yarn with a nap length of 2 to 40 mm and a nap density of 6000 pieces/cm, the length of the spun yarn will be 174 to 1 cm.
/80. In addition, the spun yarn has a nap length of 6 mm, a nap density of 6000 pieces/cm, and a thick yarn length of 100 mm @
To obtain this, a spun yarn having a thick yarn side of 1200 mm is required.

The length of the thick thread part of the mall thread is 5 to 1 in order to obtain the uneven effect.
It is necessary that the numbers are randomly mixed within the range of 000#l#I. If the thickness is less than 5M, there is no visual effect even if the thickness is increased, and the thickness is preferably 10 to 600. is good. Also,
1000. If this is the case, there will be no difference from a knitted fabric made by tying or inserting two threads of thick molding threads corresponding to a normal plain slab, and the effect of continuous thick and thin molding will be lost.

On the other hand, when trying to express the thick and thin effect of the molle yarn in a knitting or woven product, even if it is a solid slab, the napped fibers of the molle are crushed or bent during weaving and knitting. If it is not molded, the appearance of unevenness will be less, so the fine thread molding portion should be in the range of 15% to -90% of the average thickness of the molding yarn. The range of -10% to -60% is more preferable. Similarly, the thick yarn molding portion must be in the range of +50% to +900%. A range of +80% to +500% is more preferable.

Further, the slab shape is 5 to i ooo, and it is necessary to mix them randomly. In the present invention, random refers to slub yarns with different lengths, thick yarn thicknesses, and thick yarn intervals, or mixed with the same degree of irregularity as conventional slub yarns. means. A slab with regularity of a certain length lacks a natural feel and has low commercial value.

In addition, the thick yarn part that is 100% or more of the average thickness is 1007
It is preferable that 10 or more per 77 are present because a slab-like molding yarn and product fabric with a more luxurious feel can be obtained.

In addition, slab shapes with different lengths and thicknesses are ioom.
It is preferable that 10 or more types are mixed, since a slab-like molding yarn and product fabric with a more luxurious feel can be obtained.

In the present invention, the average thickness of the molle thread is 100 mol threads.
The weight per unit length (A>) is calculated by subtracting the weight per 1 oom of the ground yarn and low melting point fiber (not including any shrinkage) from the weight measured using a wrap reel.

In the present invention, the thickness of the thin thread part and the thick thread part is the unit obtained by cutting the corresponding part into 5# length, measuring the weight, and then subtracting the weight of the ground yarn and low melting point fiber, as in the average thickness. Weight per length (B).

The range value (%) of the thick part refers to the value determined by the following formula.

(B-A>/Ax 100 (%) The length of the thick thread part was determined by measuring the length of the upper bottom, since the left and right sides of the slab are thin and shaped like a solo bread top. .

In addition, the number of slabs and the type of slabs are determined by winding a 100m long mall thread on a seriplane and reading the number of slabs of the same thickness, and determining the type of slabs by 10% for both length and thickness.
Those with an increase of more than 10% were counted as 1 species. Note that the nap length is a length value corresponding to the diameter of the molding.

As a means for imparting a wide range of thick and thin unevenness to the spun yarn constituting the napped fibers as described above, for example, only the front roller of a spinning machine using a roller draft system is directly connected to a servo motor whose speed can be freely changed by a DC voltage signal. It can be obtained by a spinning method in which the traft magnification is appropriately changed by supplying a DC voltage signal obtained by converting a random number signal into an analog signal to the servo motor.

I will explain in more detail.

Fig. 3 (1) is an example of the change over time of a DC voltage signal obtained by converting a random number signal into an analog signal, and (II>) is an example of the change over time of the thickness of the spun yarn obtained by supplying the DC voltage signal to the servo motor. - The dash-dotted line represents the average thickness of the spun yarn.

FIG. 3 (I[I) similarly shows the thickness of the spun yarn, but the product of the front roller surface speed vi corresponding to each output voltage signal and each time t1, that is, the thickness of the spun yarn This shows the relationship with long [i.

For example, if we assume that the DC voltage for the average thickness is 2V, we will explain the individual unevenness patterns.First, when outputting at a voltage of 4V for 11 seconds, the speed of the front roller is twice the average speed, so the thickness of the yarn is The thickness is 150% of the average thickness and is spun for t1 seconds. The yarn length [1 at this time is the product of the front roller speed V1 at a voltage of 4V and the time t1.

Next, when output is performed for 12 seconds at a voltage of 2V, the thickness of the yarn becomes the average thickness, and the yarn length L2 becomes the product of the front roller speed v2 at the voltage of 2V and the time t2.

When the output is continued for a time t3 at a voltage of 5V, the thread thickness is -60% and the thread length L3 is the product of the front roller speed v3 at a voltage of 5V and the time 13.

Further, when output is performed for 14 seconds at a voltage of 0.5V, the thickness of the yarn is 300%, and the yarn length L4 is the product of the front roller speed v4 at the voltage of 0.5V and the time 14.

On the other hand, the front roller follows the DC voltage signal supplied to the servo motor with a fast response speed equivalent to that of the DC voltage signal supplied to the servo motor. This results in a thin shape.

As a method for obtaining the DC voltage signal used in the present invention, for example, by using the random number generation function of a computer,
Randomly select one value out of 0.999 random numbers,
Outputs a real value of an arbitrary multiple. For example, first, assume that the real value is 1ooo, the front roller speed of the spinning frame is 20 m/min, and draft conditions are set so that a fine yarn of 100 seconds can be spun.

Next, the real value 50 of any multiple of a randomly selected random number
When 0 is output, the front roller speed is 10m/m
in, and the spun yarn becomes a thick yarn of 50s. On this occasion,
In order to set the length of the thick thread portion to 5 m, it is sufficient to continuously output the real value 500 for 303 eC using a waiting time program created in consideration of the calculation speed of the computer.

An arithmetic program may be created so that the lengths fall within the range of the thick and thin parts and the range of the lengths of the thick parts of the molding yarn. In this case, the thick yarn part of 100% or more of the average thickness of the mall yarn is 10
It is necessary to create a program so that 10 or more irregularities appear per 0 m, and at least 10 types of unevenness depending on the combination of thickness and length must be created per 100 m.

The spun yarn for napped fibers used in the present invention can be obtained by the above method.

The materials of the spun yarn for the napped fibers of the mall yarn of the present invention include synthetic fibers and natural I! fibers such as cotton, silk, wool, and linen. It may be fiber or a blended spun yarn thereof, but polyacrylic fiber is preferable. It is also possible to blend cotton dyed stables of several different materials to create a unique effect. The type of stable used in the spun yarn includes, for example, fibers that can be split into ultrafine fibers by treatment with an aqueous NaOH solution, and there are no restrictions on the cross-sectional shape, fineness, fiber length, gloss, etc. Furthermore, the state of the spun yarn may be single yarn, double yarn, triple yarn, etc., and there are no restrictions on the count, twist, composite yarn with filament yarn, etc.

At the time of maul processing, the spun yarn may be additionally twisted, water sprinkled and aligned, or the spun yarn may be supplied simultaneously with other spun yarns or filament yarns of uniform thickness without unevenness, etc., as appropriate.

On the other hand, there are no particular limitations on the ground yarn and low-melting point fibers that constitute the core of the mall yarn. The yarn form may be either filament yarn or spun yarn. Regarding the material, from the viewpoint of dyeability, it is preferable that the ground yarn is made of the same material as the napped fiber.

The above-mentioned mall yarn is used to make a raised fabric, but the weaving and knitting structure can be freely selected. For example, in order to emphasize the napped effect of the napped fabric, a structure in which a large amount of napped yarns are present on the surface of the napped fabric is preferable. Preferably used are a weft double weave or backing weave of a textile, a tricot satin weave, and the like. It is also preferably used to prepare a knitting yarn by pulling together the mall yarn and the ground yarn, and to use this knitting yarn to create a single-ply knitted fabric to create a double-sided special napped fabric that takes advantage of the napped effect on both sides.

The raised fabric of the present invention is subjected to processing, setting, dyeing, brushing, and other finishing treatments of the knitted fabric. When the constituent yarns are those that can be divided into ultrafine fibers by treatment with an aqueous NaOH solution, the fibers are subjected to ultrafine treatment. The order and method of processing can be freely selected as appropriate. Furthermore, generally known finishing agents can be optionally applied. For example, finishing agents such as antistatic agents, smoothing agents, and softening agents are appropriately selected and used.

The raised fabric of the present invention can be used for all kinds of clothing for women, men, and children, such as handicraft threads, blazers, dresses, skirts, and pants, as well as for all kinds of material uses, especially furniture, multi-panels, wall coverings, sheets, curtains, and bags. is also preferably used.
