Abstract

PURPOSE:To obtain a process for producing fabric raised on both sides, enabling easy production of the fabric having long and uniform raised fibers on both faces and capable of minimizing the generation of pilling, etc. CONSTITUTION:Fabric to be raised is formed by knitting or weaving loop piles 5, 6 on both faces of ground fabric with pile yarn 8. At least the loop 6 having shorter loop length between the loop piles formed on both faces of the raising fabric is cut at the intermediate part 6a and raised or the pile is raised and simultaneously cut with the raising means. At the same time, the raised fibers are cut with a shearing to the length nearly equal to the length of the fibers on the other side raised with a raising means. Raised fibers are formed on both sides of the ground fabric by this process.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a double-sided brushed fabric in which raised hair with relatively long hairs is formed on both front and back surfaces, which is mainly used as a material for blankets and the like.

[0002]

2. Description of the Related Art Generally, a double-sided fluffed fabric having fluffs formed on both front and back surfaces of a ground structure has a pile yarn warping beam formed on both the front and back surfaces of the ground structure by a knitting machine as disclosed in Japanese Patent Laid-Open No. 5-98559. The loop pile is woven from pile yarn in the state of sweet twist or roving supplied from the company, the fibers of this loop are raised with a needle cloth roller, and finally the tip of the raised hair is cut to cut the length of the foot. The brushes are formed on the front and back so that they are even.

[0003]

When raising is formed on both the front and back sides formed by the above method, as described in the above publication, due to the mechanism of the weaving machine, the front and back sides of the ground structure are formed. It is not possible to weave fabrics with the same length of loops formed by pile yarns, and when naps are formed on the front and back by napping means such as a needle roller, the lengths of the naps on the front and back sides are If they are different, or if the raised hairs are aligned on the front and back sides, they must be adjusted to the shorter one,
There is a problem that it is not possible to manufacture products with long hair and high commercial value.

Further, the napped pile yarn still has a looped core portion, and the napped fibers are entangled in the looped pile yarn to form a ball,
There is also a problem that pilling (pillage) easily occurs. The present invention has been proposed in view of the above problems, and a double-sided brush that can easily produce a product in which the brushed hairs on the front and back are aligned in a long state and can prevent pilling and the like as much as possible. The purpose is to provide a method for manufacturing a ground.

[0005]

In order to achieve the above object, a method for producing a double-sided brushed fabric according to the present invention is to form a raised fabric by knitting loop piles with pile yarns on both front and back surfaces of a ground structure. , After cutting an intermediate portion of at least one loop having a short loop length of the loop pile formed on both sides of the raised fabric, raising is performed by raising means, and / or while raising while cutting by the raising means, the raising is performed. It is characterized in that raised hair is formed on the front and back of the ground tissue by aligning the raised hair with shirring in a state substantially equal to the other raised hair raised by the raising means.

[0006]

First, a raised fabric having loop piles formed on both sides of the ground structure is woven by a knitting machine. At this time, the length of the loop on one side (for example, the front surface) of the ground structure is long and the length of the loop on the other side (for example, the rear surface) is short.

Next, after cutting at least the central portion of the loop having at least the short loop length of the raised fabric, the pile fibers on the front and back sides are scratched by the raising means such as a needle roller to cause the fibers of the loop to be formed. Bristles are formed on both the front and back sides. Needless to say, the substantially central portion may be cut off when the loop having the shorter loop length is scratched with the cloth.

In this way, the nap formed by cutting the approximately central portion has long naps, and when the tip portion is aligned with the nap of the other nap and trimmed by shirring, the lengths of the naps on the front and back sides are increased. It is possible to form a double-sided brush having a long length.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the method for producing a double-faced raised fabric according to the present invention will be described below with reference to the drawings. 1 and 2 show a structural diagram of a double-sided brushed substrate which is mainly used as a blanket fabric. This fabric substrate 1 is, for example, KF4SFBZ or KF5SF manufactured by KARL MAYER.
A knitted fabric knitted using the knitting machine of the B-machine, the warp 2
And a weft (inserted yarn) 3 knit a ground weave 4, and loop piles 5 and 6 entwined with a predetermined warp 2 of the ground weave 4 are formed on the front and back sides to form a brushed base 7. There is.

The pile yarns 8 forming the loop-shaped piles 5 and 6 are formed by roving a coarse yarn or a sliver, and are formed on the surface portion of the ground structure 4. The front pile (hereinafter abbreviated as the front pile) 5 is formed into a long loop in a state of jumping over the two wales 10 and 11 from the loop of the predetermined wales 9 as shown by the chain double-dashed line A in FIG.

The pile 6 (hereinafter abbreviated as back pile) 6 formed on the back surface of the ground structure 4 is located at a position substantially equal to the folded portion 5a of the front pile 5 from the loop of the wale 10 near the folded portion 5a of the front pile 5. (6
It has a shape folded back in a) and is shorter than the loop length of the front pile 5 (see FIGS. 1 and 2).
reference).

As described above, in the raised base material 7 in which the long front pile 5 is formed on the surface of the ground structure 4 and the short back pile 6 is formed on the back surface, the central portion (folded portion 6a) of the short back pile 6 on the back surface is formed. It is cut by a cutting means (not shown) such as a cutter.

In this way, the short back pile 6 on the back surface, in which the folded-back portion 6a at the central portion is cut by the cutting means (not shown) such as a cutter, becomes a linear shape as shown in FIGS. The height H is longer than that in the loop shape. Then, as shown in FIG. 5, the brushing rolls 12 each having a cloth cloth planted on the peripheral surface and the pressing blades 13 facing the brushing rolls 12 are alternately passed through the brushing means 14, so that the brushed base 7 is covered with the brushes 7. The fibers of the front pile 5 and the back pile 6 thus formed are alternately scraped.

At this time, when the loop is cut at the folded-back portion 6a at the central portion like the back pile 6, there is no twist component in the loop, and the cloth 12a of the brushing roll 12 can be easily passed through it. It can be raised.

In this example, the back pile 6 having a short back surface is used.
The looped portion 6a of the loop is cut by the cutting means, but the folded portion 6a of the loop is formed by the clothing cloth 12a of the brushing roll 12 forming the raising means 14.
Needless to say, a may be scratched and opened (cut), and the front pile 5 on the surface may also be cut by a cutting means.

However, when the fibers of the back pile 6 are scratched and raised by the nap raising means 14, they are further stretched and stretched, so that the napped fibers of the napped fibers become longer.
After that, the ground structure 4 is formed by a shearing device (not shown).
When the lengths L of the naps formed on the front and back are aligned as shown in FIG. 6, the soft napped cloth 15 with long legs is formed on the front and back as shown in FIG.

The napped cloth 15 thus formed is rubbed by a tumbler device to give flexibility, crushed by a steamer device, processed by a post-processing device which is spread by a tenter device, and a blanket material. It becomes a product. In addition, in the above-mentioned embodiment, the description is given by taking the blanket fabric product as an example. However, it is not limited to such a product, and it can be used not only for towels but also for cosmetics such as putting materials and hygroscopic materials. It goes without saying that it can be widely used as a material.

[0018]

As described above, the method for producing a double-sided brushed fabric according to the present invention forms a raised fabric in which loop-shaped pile hairs are planted on the front and back of the ground fabric, and forms it on the front and back of the ground fabric. Of the loops formed, at least the loop having the shorter loop length is cut at the substantially central portion thereof, and the fibers are scraped and raised by the raising means to form raised hair, and the raised hair has long hair legs. Therefore, when the tip portion is aligned with the fluff of the other raised hair and trimmed by shirring or the like, it is possible to form double-faced raised hair with the same length of the fluff on the front and back. As a result, there is an advantage that it is possible to easily manufacture a woven fabric in which high-quality double-faced brushes with uniform lengths of the front and back are formed.

Further, unlike the conventional case, no loop-shaped nucleus remains in the raised portion formed by scraping the fiber by the raising means in a state where at least the substantially central portion of the loop having a short loop length is cut. Therefore, there is also an advantage that it is possible to prevent the occurrence of pilling or the like caused by the entanglement of fibers by the loop portion as much as possible.
