Abstract

PURPOSE:To provide a sufficient downy hairy appearance at a low fiber density by forming stinging hairy pile parts and down hairy pile parts from pile tip parts and root parts formed from fiber yarn of the same Y-shaped cross section. CONSTITUTION:Fiber, having crimps and Y-shaped cross section and splittable by shock alone or yarn containing the aforementioned fiber is used as fiber yarn for forming piles to form the piles on the surface of a pile base fabric 1. The surface of the base fabric with the formed piles is then slid and rubbed while being shocked and beaten by a rotor provided with projections on the surface in a heated state to split tips of the piles into plural parts. Crimps at the tips are simultaneously removed to form stinging hairy pile parts. Thereby, a pile fabric composed of the stinging hairy pile parts 2 and down hairy pile parts 3 is obtained.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to pile fabrics used for artificial fur, stuffed animals, rugs, etc. This invention relates to a pile fabric made of pile-forming am.

[Conventional technology]

Efforts to make pile fabrics closer to natural ones are *m
It has been continued without a break since the fabric was formed, and the pile is made long and short, and the 11! In addition to old methods such as changing the diameter, in recent years, as natural fur has become difficult to obtain due to considerations of wildlife protection, methods such as sharpening the tip of the hair and using ultra-fine fibers as downy hair have been introduced. Coupled with the recent advances in l11ton development technology, efforts have begun to seriously develop products that will bring them closer to natural piles.

[Problem to be solved by the invention]

A common method for sharpening the tips of synthetic rattan fibers for piles, such as stinging hair, is to immerse the tips of the piles in a fiber solvent to partially dissolve them.
Many proposals such as 460.58-36267.65-245570 have been made, but when performing the above-mentioned sharpening treatment in the system state before pile formation, the sharpened portion is positioned at the tip of the pile during pile formation. This is the main shock, and if sharpening treatment is applied after pile formation, the pile formation surface should be even!
It is difficult to add a solvent to the dye, and there are disadvantages such as the dyeing performance differing due to the denaturation of the entire sharpening treatment. : Obtained from: 1Lnc, There have also been proposals to use the thick and thin type of pile for piles, but it is difficult to position the pile tips accurately.

Furthermore, a major difference between synthetic fibers and natural fur fibers is the presence or absence of waist of each fiber. This is Synthesis II1.
While the fiber diameter of M1 is uniform, in the case of natural fibers, the fiber diameter gradually decreases from the root to the tip.
This is because it has a structure that makes the pile less prone to lodging than synthetic JIII.

The present invention aims to solve these problems and provide a pile fabric that is easy to manufacture.

[Means to solve the problem]

The first gist of the present invention is that the bristle-like pile portion and the downy pile portion are formed of the same pile, and that the bristle-like pile portion and the tips of the fibers constituting the pile are It is composed of a Y-shaped cross section q1 that is non-crimped and divided into multiple parts at random lengths, and the downy hair-like pile part is composed of the root part of the fibers that make up the prickly hair-like pile part. , the root part,
It is a pile fabric characterized by having an undivided Y-shaped cross-section am having crimps and twists planted either singly or in a convergent manner with other hawks, and the second gist is: In a method for producing a pile fabric consisting of a hair-like pile portion and a downy pile portion, a yarn having a crimp and having a Y-shaped cross-section am that can be split by impact or having one or more yarns is used as a pile-forming fiber. A pile is formed as yarn on the surface of the pile base fabric, and then the surface of the base fabric on which the pile is planted is rubbed and impacted using a heated rotating body with protrusions on the surface, and the tip of the pile is A method for manufacturing a pile fabric, characterized in that a section is divided into a plurality of pieces and, at the same time, a crimp at the tip is removed to form a pile section in the form of bristle.

The present invention will be explained in detail below with reference to the drawings.

Fig. 1 and Fig. 2 are partially enlarged views showing an example of the form of the pile fabric of the present invention as a model. A hair-like part and a downy part are formed, and Fig. 2 shows one in which downy hair is formed separately using other *a in the downy part, and (1) is a pile base fabric. (2) is a hair-like part at the tip of the pile made of fibers with a Y-shaped cross section (5), and a downy part (4) at the root of the pile made of fibers with a Y-shaped cross-section is a hair-like part made of other fibers. are shown respectively.

In Fig. 1, the pile is formed of fiber threads with a Y-shaped cross section or fiber threads containing fibers with a Y-shaped cross section, and the tip of the pile has a prickly part (2) of the pile. The root part constitutes the downy hair-like part (3), and the pile base fabric (1
) is planted.

The bristle-like part (2) at the tip of the pile is formed by dividing the individual Y-shaped cross-sectional fibers that make up the thread into multiple pieces at random lengths, as shown in the figure, to form a sharp end. , the downy hair-like part (3) at the root of the pile is formed by the crimp and Y
Shape I with a twist peculiar to fibers with a letter-shaped cross-sectional shape! It has a dense appearance while maintaining its elasticity.

In this case, it may be formed as a pile fiber with Y-shaped cross-sectional fiber threads, or it may be formed with other fibers or other downy fiber threads used in combination.

Further, the divided bristle-like portions (2) at the tips of the Y-shaped cross-sectional fibers have no crimps as the crimps imparted during the production of the fibers a have been removed.

@Figure 2 shows a downy hair-like part (3) made of fibers with a Y-shaped cross section.
This shows an example in which a downy part (4) is further formed using other fibers, and two types of downy part are used in combination, and the combination of the downy part increases the density of the root part of the pile, resulting in a pile. It has a structure that prevents the surface of the base fabric from being exposed.

The method for forming piles in the pile fabric of the present invention includes the generally known sliver knit method, f'L; Various methods can be adopted, such as raising tufted fabrics, 21i kimonos, non-woven fabrics, etc. using a lifting machine.

The pile base fabric (1) used in the pile fabric of the present invention
) is used as a normal pile base fabric such as m-woven fabric or non-woven fabric, and if necessary, a nine-base fabric made using shrinkage fiber yarn etc. may also be used.

The Y-shaped new type fiber yarn used as the pile is made of V-synthetic fibers such as polyester fibers, nylon fibers, or acrylic QJI fibers, and is known as the cross-sectional shape of the collar. It is possible to use this item.

′-! In addition, even if the Y-shaped cross-sectional fiber is used alone as a pile yarn, it is round when used in combination with other yarns.

Also, J#! Fibers with a thickness of about 1 to 40 d are used as the weed, and I11 wed with a length of 20 to 76 cm is used as the fiber length.

Furthermore, if the thin foundation is used as a downy pile (4) that is mixed or used in combination with the Y-shaped cross-sectional Jl foundation, the density of the downy hair can be improved.

Next, a method for manufacturing the pile fabric of the present invention will be explained.

The Y-shaped cross-section fiber used as the bristle-like pile (2) is a known wax obtained by spinning and drawing using a discharge nozzle whose discharge holes are all Y-shaped during the production of synthetic fibers. Kubayo <' @

11l! It is necessary to divide the strands into nine parts to form a sharp end, and the electric equipment is likely to occur as a result of the lid M manufacturing. It is preferable to use a mold cross-sectional shape that is easy to divide into one piece with a neck and one L part.

Depending on the method of forming the pale cloth 4, the Y-shaped fr surface shape) can be made with spruce, sliver, multi-fila, or bulky yarn, depending on the method of forming the pale cloth 4.
Eight years ago.

Sliver spun yarn consisting of such a Y-shaped cross-sectional shape, multifilament knitting, weaving, milling, double latse, and touch ink to form a pile, Y After the web having the letter-shaped cross-sectional shape *i is subjected to needle/unching, it may be raised to form a pile.

As the pile base fabric (1), as described above, a woven or knitted fabric or a non-woven fabric made of natural fibers or synthetic fibers (yarn) is used.

F'L fiber yarns for pile are formed on the surface of the pile base fabric (1) by uneven formation, planting, chiruike touch 1', etc.
The pile fiber yarn is constructed by brushing or double-plying, then shearing, and rubbing the thread + O tip with a rotating body with protrusions on the surface, such as by brushing and scraping. At the same time, the tip end of the shape aS yarn is divided into a plurality of pieces in a random manner, and at the same time, the steep pile yarn is buffed.

In this case, the above-mentioned rotating body is heated to a temperature higher than the softening point temperature of the Y-shaped cross section a-cone used as the pile fiber yarn, and the tip of the yarn is struck and rubbed.
The tip portion of the fiber with a letter-shaped cross section is repeatedly stretched in a heated state, and crimps can be removed at the same time as the splitting process.

In this way, by using the same pile mis yarn, the tip part is uncrimped and has a sharp dove due to division, resulting in a bristle-like pile part, the root part has crimps, and A pile fabric is formed that has a downy pile portion with a dense appearance in which the fibers are intertwined with each other.

Example 1 Acrylic resin having a Y-shaped cross-sectional shape with a fineness of 10 denier and an IIJI length of 38 strips was dyed using an Obermeyer type dyeing machine, softened and dried to obtain an east line.

This eastern wire was attached to a card machine, and a sliver with a weight of 14 tons per 1fP was spun.

This sliver was placed in a sliver knitting machine, and a knitted fabric having a weight of f1001 per puddle was knitted.

In this case, the ground thread and 1-thickness are 100% polyester and 22% polyester.
Two spun yarns of the same count were used.

After tearing the knitted tube, it was back coated with acrylic resin and heated at 120°C to 130°C to fix the pile.

The pile was then cut to a length of about 18 cm using a shearing machine, and then subjected to polylash processing at temperatures of 170°C, 150°C, 130°C, 110°C and 90°C to remove the crimps of the raised wax fibers.

Furthermore, the length of the pile to be sheared using a shearing machine was set to 201, and only long and protruding piles were cut.

The resulting raised fabric has a divided pile tip and is formed in a non-crimped shape, giving it a tapered appearance and a soft texture, while the pile root is not divided and is interlaced with each other. However, it was bulky and had a downy hair-like appearance.

Example 2 Y-shaped cut 'F with fineness of 10 denier and fiber length of 58-
An acrylic wax fiber having an fJyPI shape was dyed using an Obermeyer type dyeing machine, softened, and dried to obtain an east line.

Further, a dark brown acrylic fiber having a fineness of 4 denier, an A11 length of 32 denier, and a shrinkage rate of 304 in air at 130° C. was prepared. 40 each of these two additional staple fibers.
The cotton was blended at a ratio of 4.604 and spun using a roller card #aK machine into a sliver weighing 14 tons per 1 meter length.

The weight of each sliver of 1 sliver is 1
200t of knitted fabric is S! Rt.

In this case, as in Example 1, polyester 1
Two spun yarns with a count of 004.22 were used in parallel.

After the knitted cylindrical knitted fabric was torn, it was back coated with an acrylic resin and heated at 120 to 150°C to fix the pile. Next, use a shearer to reduce the pile to about 18.
■Cut to length -1.

In this case, acrylic type! 11 m contracted by approximately 304 m and sank to the base of the pile.

This knitted fabric was further heated to 170°C, 150°C, 130°C, and 110°C.
℃ and 90℃ with poly lash processing and raised *
After removing the crimp of .

The resulting Kutari blanket is formed into a non-crimped shape with split ends of the pile, which has a tapered appearance and soft texture, while the base of the pile has a split, loose part and a shrunk acrylic. The fibers interlocked with each other, giving it bulk and a two-layer structure with a split np pile at the tip.

〔Effect of the invention〕

The pile fabric of the present invention has the same Y-shaped JFriTll-like pile part and the downy pile part! It is made of fibrous filaments and is made up of the tip and base of the pile, and only the tip of the pile is randomly divided into multiple pieces, resulting in no crimping. It has a sharp edge shape, and it does not require any new processing to form the sharp edge, and it is possible to industrially form the sharp edge pile by a hassle-free method after forming the pile fabric. In addition, the pile base is made up of undivided Y-shaped fibers with a new surface shape, and is also created by the twist peculiar to the Y-shaped cross-sectional shape and the crimp applied during the manufacturing process. The intertwining of the fibers gives it a dense appearance, and a small* fiber density can provide a sufficient downy appearance.

Historically, since fibers with a Y-shaped cross section are wrapped around the pile, the pile becomes strong, and this has great effects, such as eliminating the sagging of the pile that is typical when using synthetic fibers.
