Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to fur-like napped products, in particular to napped products having a unique appearance, soft feel and eroded bulk.

Although many artificial furs have been proposed in recent years, the appearance and
Unsatisfied with the feel etc.

The purpose of the present invention is to obtain a unique appearance in which the erected hairs form a large number of aggregates, which have an irregular but slightly regular shape, such as a planar pattern resembling a scale cloud or a sardine cloud (altocumulus cloud, cirrocumulus cloud). arranged to form a bulky structure,
The purpose of the present invention is to propose a new and advanced napping product that has heat retention properties and a soft and excellent texture.

The napped product of the present invention is (a) a fiber structure having cut pile nuffs with a length of 8 sides or more, (b) a narrowed part with a length of 2 wIb or more at the top and bottom of the napped piles and a length of 5 lbs. Each of the above-mentioned non-thinning parts has the above-mentioned non-thinned parts, and (c) the non-thinned parts are different from curled fine hairs with a fineness of 6d or less and bristles with a fineness of more than 6d)
It is characterized in that the tops of the naps are intertwined with each other to form a block structure with a diameter of 2 to 20 mm. In the present invention, the term "fiber structure" refers to braided fabrics, knitted fabrics, nonwoven fabrics, and similar fabrics. The non-narrowed part of the nape refers to a zone where the fineness of the nape does not substantially change in the length direction. The thinned area refers to a zone where the fineness of the erect hairs (bristle and/or fine hair) is reduced (for example, on average 5Q% or more, particularly 50% or more) compared to the non-thinned area.

FIG. 1 is an explanatory cross-sectional view showing an example of the product of the present invention. In the figure, (1) is the base fabric (equivalent to natural fur skin).
(2) is a yarn (pile yarn) constituting the raised pile, and the yarn is made up of thick bristles (5) and fine curled hairs (4). The erect hairs are intertwined at the top to form a lumpy structure (5). The upper part of the nape is thinned, and the length of the thinned part is shown in (B). The length of the non-thinned part at the bottom of the piloerection is shown. In addition, the diameter of the massive structure at the intertwined part of the piloerection is indicated by (0).

The figure shows two pili aggregates, the gap between which is indicated by Φ).

The size of the gap (D) (width) is usually about 1J, 5~7■,
In most cases, it is 1 to 5 times long.

The piloerection is focused by apical interlacing.

In the non-reduced portion, the pile yarns may be intertwined inside, but the pile yarns are not substantially intertwined with each other. Therefore, due to deformation of the base fabric, etc., the gaps) change, giving the product a three-dimensional appearance and change.

When viewed from above, the focusing body has an amorphous shape, for example, a soft lump like cotton or a cloud, and its diameter is expressed as an average value, such as fIJ, which is the average value of the maximum diameter and the diameter in the direction orthogonal to it.

Setae (5) are important for giving tension and stability to the erect hair aggregates, and without them, the aggregates are easily collapsed and compressed.
Unable to maintain bulk. The fineness of the bristles must be greater than 6 d to achieve the above objective, preferably 7 to 50 d, most preferably 10 to 30 d. If the bristles are too thick, the product will be hard (and the feel and texture will be inferior).
A Y-8 shape and a hollow shape are also preferred.

For example, the bending hardness of ellipses and rhombuses changes depending on the direction, but it is sufficiently effective if they exist in large numbers irregularly in the aggregate. Preferably, the bristles are attenuated or cut at the attenuation. The tips of the attenuated bristles may form an interlace or may exist independently of the interlace. If the bristles reach the tip fr and reach the top of the aggregate without being thinned, the appearance and feel will be significantly impaired.

Although the bristles may be crimped, uncrimped bristles are preferred in most cases from the standpoint of bending elasticity.

The fine hairs (4) must be curled. The crimping provides bulk, insulation, flexibility, and a rich appearance. The crimp may be mechanical crimp such as false twisting method or pressing method.
Spontaneous crimp by composite spinning may also be used. The fineness of fine hair must be 6 d or less, preferably 0.5 to 5 d, and 0.8
-4d is most preferred. It is necessary for fine hair to be thinned at the thinning part. Splitting (fibrillation) is also a type of purification, and is the most preferred embodiment of the present invention.

It is one of the best. Also, a portion of the bristles may be cut off at the thinning section. When all of the fine hairs are cut off and the intertwined portion is formed only from thinned bristles, the appearance tends to be poor, which is undesirable. The length of the thinning part B) is 2
Requires more than a decoy, preferably 3-20, 5-15
Words are most preferred.

The length of the non-thinned part must be 5 or more, preferably 7 to 40, and most preferably 10 to 3. The mixing ratio (weight) of bristles in the non-thinned part is preferably 20 to 80 bristles,
60 to 70 inches is most preferred. This is because if the mixing ratio of MII hair is low, the product will have poor bulk and stiffness, and if it is too large, the product will have poor flexibility and heat retention.

The non-A+1llt group preferably stands upright or at an angle close to it with respect to the base fabric, preferably at an angle of 450 or more, particularly 609 or more with respect to the base fabric □ This uprightness h%
These are extremely important factors that give bulkiness, non-softness, heat retention, pleasant texture, and rich external appearance to lachrymal products, and one of the important features of the present invention is that this erect property is maintained by the dark hairs. It is one.

Intertwined area: It is irregular in shape, and its diameter is 7 I'li, but most of it (area seen from above is 50φ or more, especially 75 mm)
% or more) is in the range of 2-25 seagulls.

Whether the diameter is small or large, the design effect is inferior. From a design point of view, it is feminine that the l diameters are naturally (randomly) distributed and arranged in the range of 6 to 20 mm.

Next, the method for manufacturing the product of the present invention will be described.

'The fibers used to form the product of the present invention are not particularly limited, and synthetic fibers and natural fibers may be freely selected and used in combination as necessary.

For napping, synthetic *a fibers made of thermoplastic resins, such as polyester, polyamide, acrylic fibers, etc., are preferred.
For the purpose of thinning the upper part, the left side of the bristles and the small amount of fine hairs (
It is effective to use polynisglue, which is easily decomposed with alkali, as a part of both. Of course, methods such as thinning the fibers, decomposition with a splitting agent, and dissolution with a solvent can be applied, so choose a polymer that meets the purpose.

〇Napped products can be obtained by well-known methods such as pile paper machine, pile cotton type, tufting method, etc. 0 sliver single knitting machine, and the flocking method can also be used, but the quality (uniformity) etc.) are inferior, but in order to obtain high-quality products, the pile assembly machine (
For example, a double pile loom) is most preferred. It is most convenient to use a yarn for piles that is a blend of bristle fibers and fine hair fibers, or a combination or twist.Although it is possible to blend O staples, it is preferable to use long fibers instead. is preferable. (In a sliver knitting machine, a stable for bristle and a stable for fine hair are used together.) The fineness of the fiber for bristle is more than 6 d, preferably 7 to 50 d, and most preferably 10 to 6 υd. The cross section may be circular, but non-circular is often preferred. Although it may be crimped, it is preferable that it is not crimped or that it is weakly crimped. Since it is preferable that the tips of the bristles be thinned, it is advantageous to use a polymer that can be easily thinned, for example, one that has improved decomposition and solubility by mixing or copolymerizing with a third component.

The fiber for pure wool is 6 d or less, preferably 0.5 to 5 d. 0
．． ．． 8-4d is the most preferable. For crimping, a mechanical method such as a false twisting method and a pressing method, and/or spontaneous crimping by composite spinning are used. For crimping in the false twisting method, it is often preferable to use a two-stage heater method to suppress (weaken) the crimping and make the material latent. This is because if the crimping or torque is too strong, the bulkiness may be warped and lost, or entanglement may occur in unnecessary places (such as non-thinned parts). A conjugate fiber having spontaneous crimp property may be used as a pile yarn with part or most of the crimp exposed, or may be used in a latent state and caused to develop crimp in post-processing. Furthermore, as a method for thinning the upper part of the nap, a method of dividing the composite fiber is preferably used.

A split-type conjugate fiber that can be easily divided by appropriate means such as dissolution, decomposition, swelling, etc. of one component can be used.

Figures 4 to 10 are cross sections showing examples of composite fibers that can be used in the present invention; two types of polymers (S),
+61 is connected. Figure 4 is an adjacent type, and Figure 5 is
The figure shows a core-sheath type, and FIG. 6 shows an eccentric core-sheath type. 7th
Figure 8 shows a radial type, and Figure 9 shows a hollow radial type, with the hollow part indicated by (7). Figure 10 shows a non-circular multilayer adjacent type. Eccentric joints as shown in FIGS. 4 and 6 have spontaneous crimp properties. The materials shown in FIGS. 11 to 10 can be thinned and split by dissolving or decomposing and removing one component.

Those in FIGS. 8 to 10 show poor mutual adhesion [7] Even when the vJ synthesis components of a combination of components (for example, polyamide/polyester) swell, they can be divided [7].

Fig. 11 shows an example of hollow fibers, and Fig. 12 shows an example of an X-shaped cross-section yarn, which has a large bending stiffness and is suitable for stiff bristles. Of course, all shapes other than those shown can be used.

The fibers for fine hair and the fibers for stiff hair are mixed and combined into one piece, and if necessary, twisted to form a set of pile yarns. As mentioned above, spun yarns made of staples can also be used, but since a continuous filament can provide a more uniform product, the ratio of fibers for bristles and fibers for fine hairs in the 0-pile system is preferably determined by the mixing ratio of fibers for bristles ( It is preferable that the weight) is 2o to 80%, especially 5Q-70% □ The number of fibers for bristles and M11 fibers that make up the pile yarn 4'IQ, the total Rt degree, etc. Depending on the raised density of the product, the flocking density of the knitting loom, and the finishing process, a! It can be worn for a week taking into consideration the shrinkage of the near cloth. In most cases, the total fineness of pile yarn is IQQ ~ 400d.

In particular, the flocking density is 200 to 3DOd (one pile yarn is placed in one place and the hem).For W-shaped or V-shaped flocking, one W-shaped or
It is advantageous to have about 60 to 120 places/d (counting as 2 places of hair transplanted) □The density of raised hair in the final product is:

degree is preferred.

The ground thread constituting the base fabric may be a #1 black thread, or may be a continuous filament. It may be crimped or crimped. Natural fibers such as cotton and wool may be used, and artificial R fibers such as rayon, boonamide, polyester, and acrylic fibers may be used. The total fineness is also arbitrary, but in most cases, a fineness of about 100 to 500 d, especially about 200 to 4 DOd is often used.

For cut pile knitted fabrics, etc., finishing processes are performed such as purification of the upper part of the nap, dyeing of the nap, resin treatment of the nap, heat setting, and impregnation of μ゛ with fat into the base fabric. Regarding the purification processing of raised hair, the present inventors have developed a new and advanced processing method using centrifugal force to raise the raised hair and bring it into contact with a processing liquid in Japanese Patent Application Laid-Open No. 56-1548.
Disclosed in issue fS. This method of utilizing centrifugal force can also give the product of the present invention a favorable standing state of the nape, in addition to heat fixing the nape in an erect state.Similarly, centrifugal processing can be used to dye It can be bleached to give a pimple-like color.

In addition to centrifugal processing, thinning of the nape, heat treatment for raising the hair, dyeing power, etc., cutting of the hair and division of the remains of the nape can also be performed. These are 49 rail 1984-37354 column.

Since it was explained in detail in Iviit No. 57-121645, etc., the explanation will be omitted.

1. ,! ! The fibers can be easily entangled by rubbing the upper part of the fluff after thinning in water or air with light force or with a brush. It is also effective to spray a stream of water to disturb the piloerection or stir it in the water. Furthermore, if appropriate fibers are used, intertwining can be achieved very easily.The important conditions for easy intertwining are that the fibers are thin, long, and crimped. The fineness is preferably 3 d or less, particularly 2 d or less, and 0°1 to 1.5
d is most preferred.

It is preferable that the fibers are thin because they give extremely soft and strong feel. The fiber length required for intertwining is approximately 1 to 20 Mb.
In particular, the most common words are 2-15 words and 5-10 words. The stronger the crimping, the stronger the entanglement. Similarly, fibers with a flat cross section (those with a large length/breadth ratio) have a high degree of entanglement.

If the entanglement is high, it will be easily entangled, but if it is too strong, it will become pill-shaped and spoil the aesthetic appearance, so the above-mentioned factors and the entangling operation should be adjusted to adjust the entanglement to an appropriate level.

The size of the entangled portion can be adjusted so that the diameter of most of the portions is 2 to 25 mm, particularly 3 to 20 mm, by adjusting the interlacing properties of the fibers and the interlacing operation.

Figure 2 is a photograph showing an example of an intertwined fiber aggregate, in which intertwining occurs at the top, but there is almost no intertwining between the pile yarns at the bottom. In the example in this photo, the open hair is not curled and contributes little to entanglement; its function is to keep the entire standing hair erect and bulky. FIG. 3 shows a photograph W of the present invention of a napped product having intertwined tops, illuminated from the side and shadowed from above. Create a mackerel cloud-like pattern l'C
Many aggregates are naturally arranged irregularly. The scale unit in the photo is 11, and the diameter of the intertwined part (d major j) is about 4 to 15. Even just the concavities on the surface as shown in Part B have a great design effect, but it is also possible to add color effects to this. For example, by centrifugal processing, the hue, saturation, and /
By changing the brightness and brightness, you can easily see high-quality peeping items. By changing the color at the upper and lower parts of the nape, the product of the present invention is given a three-dimensional, flowery appearance that is not found even in natural wool fabrics. This is because the pattern of the interlaced areas is emphasized, creating a clear contrast and subtle harmony with the color form of the suberect piloere i'ill visible through the gaps between the erected piloere bundles. Therefore, the gap between the bundles (the size of which is indicated by D in FIG. 1) is extremely important for the design effect of the product of the present invention.

In FIG. 5, this gap is a dark area, and most of it (more than 50 inches in area) is about 1 to 5 inches in size. Large gaps can be seen in some areas, but their size is at most 1 cs.

Typical examples of effective color combinations for the interlaced area and the lower part of the erected hair are ``a combination in which the interlaced area is white or light colored and the lower part of the erected hair is a medium to dark color'', ``the interlaced area is medium to dark color, and the lower part of the erected hair is a light color''. or a combination of white, and a combination in which both are light to medium-dark and have different hues. The hue used is red-yellow, yellow, yellow-green, green, dorsal edge, blue, navy blue, purple, brown, brown, black, gray, etc., and the interlacing part and the lower part of the erected hair are the same color or similar color. (
For example, red/(distortion, ft/)jc green, brown/post, etc.) may be used, or silk combinations of opposite colors (e.g. red/green, red/blue, yellow/f) may be used.
