Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a fur-like napped product, particularly a napped product having a striped surface variation.

(Prior Art) Products with raised piles, such as cut piles or loop piles, have unique and diverse appearances and textures, and are widely used. One purpose of producing these pile products is to obtain natural fur-like products. However, natural fur has very complex and subtle colors and shapes, and although there have been many attempts to artificially produce similar fur, they are still unsatisfactory.

The present inventors proposed a method of obtaining a fur-like nap product by highly processing the nap of a raised fabric in Japanese Patent Publication No. 59-45788, and also in Japanese Patent Publication No. 61-18020, In Japanese Patent No. 86108, a raised product having a high degree of color change was proposed. This made it possible to produce highly advanced artificial fur.

However, attempts to change the surface condition of piloerection,
Very little has been done yet.

(Problems to be Solved by the Invention) An object of the present invention is to provide a napped product that has striped surface changes that are continuous in the longitudinal or latitudinal direction and has a new and highly aesthetic appearance.

(Means for Solving the Problems) The fur-like napping product having a striped surface change of the present invention is a fur-like napping fabric composed of a mixture of thick, long prickly hairs and thin, short fluff. In this case, the prickly hairs are composed of a piloe group (4) with strong curling and a piloe group (6) with weak curling, and the piloe group (4) and the piloe group (2) are continuous in the longitudinal or latitudinal direction. It is characterized by being arranged in a striped pattern.

The present invention will be explained below with reference to the drawings. FIG. 1 is an explanatory diagram of the fur-like nap product of the present invention. In the figure, (1) is fluff, (2) is prickly hair, and e) is base fabric. Of the prickly hairs, M is a raised piloe with strong curling, and B is a raised piloe with weak curling. The base fabric (3) can be freely selected from woven fabrics, knitted fabrics, non-woven fabrics, and similar materials thereof, but dense, flexible, and light woven fabrics, such as those with a weight per square meter of 200 g or less, particularly 50 to 150 g, are suitable. ing. Of course, it may also contain an adhesive (polyurethane resin, etc.) for fixing or stabilizing the piloerection or tissue. The raised part has a two-layer structure of prickly hair (2) and fluff (1).

The bristle (2) needs to be thicker and longer than the fluff (1), so that it can give the product desirable bulk, firmness, texture, and manageability. Preferably, the fineness is 10 d or more, and 25 to 50 d.
is particularly preferred. If the fineness of the pricking hairs (2) is too small, the straightness and waist of the prickling hairs cannot be satisfied. Stinging hair (
2) The length is preferably 5 mm or more, particularly 10 mm or more longer than the fluff. The bristles (2) are made of a fiber-forming synthetic polymer, and the synthetic polymer includes polyester,
Polyesters, particularly polyethylene terephthalate and polybutylene terephthalate, are preferable materials because polyesters, especially polyethylene terephthalate and polybutylene terephthalate, can be used in the tip sharpening treatment, although polyamide, 4-lyolefin, etc. can be used. The cross-sectional shape of the bristles (2) is preferably flat, and it is more preferable that the bristles (2) are flat filaments with a flatness of 1.4 or more. As shown in FIGS. 2 to 16, the flat cross section may be a diamond shape, a cross shape, an eyebrow shape, or an oval shape, but a diamond shape or a cross shape is preferable since the tip can be sharpened well. In terms of gloss, the flatness is preferably 1.4 or more, and 1.7 to 8.
5 is more preferred.

Flatness is the ratio of the major axis to the minor axis of the cross section.

The fluff (1) is thinner and shorter than the stinging hair (2). Fluff (2)
The material may or may not have crimp, but it is preferable to have weak crimp in order to provide appropriate bulkiness. Crinkage can be imparted to the fibers by methods such as false twisting, indentation, and composite (joint) spinning. In order to obtain a weakly crimped yarn, the conditions of the crimping process may be selected so as to suppress crimping. The fluff (1) preferably has a fineness of 0.5 to 8 d1 and a length of 8 mm or more from the viewpoint of flexibility.

An important feature of the present invention is that the piloerection (2) is composed of a piloerection group (4) having strong curling and a piloerection group (B) having weak curling; The group (3) is arranged so as to form a continuous striped pattern in the longitudinal or latitudinal direction.

Strong crimping means, for example, the number of crimping per cm is 0.8 to 8.
61, and the nap group (2) is preferably one in which the nap fibers are curled and twisted like the nap shown in FIG.

If the number of curls is too large, the fur-like texture of the napped product will be lost, which is not preferable. As shown in Figures 8 and 9, as a measure of the strength of crimping, the amplitude of deflection with respect to the maximum length 1 when the raised hair is taken out and projected onto a glass plate (slide glass) under no tension is measured. Using the ratio (referred to as amplitude ratio) Va, the piloerection W#(4) is b
/a is preferably 0°1 to 0.8. On the other hand, weak crimp refers to one in which the number of crimp is 0.1 or less per cm, and the raised pile group (B) also includes straight ones with substantially no crimp as shown in FIG. The strength of curling is the piloerection group (G)
It is preferable that b/a is 0.1 or less. The method of measuring crimping is to immerse approximately 20 cm of the fiber used for pricking in water for 1 minute without any load, and then measure the number and strength of crimping after air-drying. 1 with a great curl!
A method for producing fibers without AIi and crimp will be described. Even if the yarn has the same cross-sectional shape, the degree of crimp after the Sumoto treatment of the yarn obtained by spinning and drawing changes depending on the melt spinning temperature, the temperature and air volume of the spinneret yarn cooling air (hereinafter referred to as 4), and especially In the case of a thread with a flat cross section, the degree of curling changes greatly depending on the angle at which the palm touches the thread. As shown in Figure 10, when the flat long axis is perpendicular to the direction of the palm and the air flow is large, the fibers are cooled asymmetrically and the development of curling is extremely large, and as shown in Figure 11, the flat long axis is perpendicular to the direction of the palm. When the long axes are parallel and the air flow is small, the fibers are cooled symmetrically and little or no crimp occurs. Furthermore, fibers with crimp can be obtained by composite spinning of 2 m polymers with different shrinkage properties in a side-by-side type or other eccentric relationship. It's easy to change.

Next, the arrangement of the piloerection group (4) and the piloerection group (2) will be described.

In the case of double pile weaving, it can be easily manufactured by warping the raised piles 8#(2) and the raised piles group 2 every few times during warping, and weaving using these warps. In the cut pile state, both the piloerection group (4) and the piloerection group (6) are straight and the same.
Even if the pile height is high, due to heating during water production, alkali reduction treatment, dyeing, drying, and other finishing processes, the pile
4) Curling occurs, the upright state is disturbed, and there is a step in the nap height. On the other hand, the nap group (6) with weak curling does not curl or only curls very weakly, so the nap is almost uniform. The two groups of raised hairs differ not only in surface uniformity but also in light reflectivity and/or raised height, so even if dyed to the same tone, depending on the viewing angle, shiny parts and non-shiny parts will change over time. It looks like stripes, and at certain angles, dark-colored parts and light-colored parts appear as stripes.

In addition, when creating a similar striped pattern in the weft direction, a horizontal pile weave can be used.

The width of the striped pattern may be arbitrarily selected from an aesthetic point of view, but in most cases, the width of the napped group (2) is preferably 1 to 80 mm, more preferably 8 to 80 mm. If the width of the piloerection group (4) is too large, the piloerection may become noticeable and the aesthetic appearance may deteriorate. Also, the interval between the stripes of the piloerection group (2), that is, the piloerection #(B
) is preferably 2 to 220 mm, more preferably 20 to 150 mm, for the same reason.

The napped density of the napped fibers that make up these prickly hairs and fluff,
There is no particular limitation on the ratio of prickly hairs and fluff in the piling, but from the viewpoint of the lightness of the product, the ease of handling the pilings, and the bulkiness, the density of the prickly pilings is preferably 60 to 1000/cm2, particularly 100. -500 pieces/cm2 is preferable, and the nap density of fluff is preferably 8,000 to 80,000 pieces/cm2, particularly preferably 6,000 to 15,000 pieces/cm2.

A softening and smoothing agent may be applied to the piloerection. In addition, it is preferable that the raised hair be laid (formed) in a regular manner in a certain direction, preferably with a slight disturbance while maintaining a natural impression, and that its state be stabilized by heat setting or the like.

The base fabric is required to have high flexibility, and the adhesive resin applied to the base fabric is preferably as flexible as possible, such as polyurethane elastomer, silicone resin, acrylic resin, etc. The smaller the amount of resin deposited, the better from the viewpoint of flexibility and lightness of the base fabric, and usually 80% by weight or less (based on the weight of the base fabric fibers) is preferably 80% or less, particularly preferably 6 to 20%.

(Example) Hereinafter, the present invention will be specifically explained with reference to Examples. Polybutylene terephthalate having a relative viscosity of 2.46 is melted into a polymer at a temperature of 276°C, a temperature of 80°C, and a flow rate of QA of 1.
40 cm 8/hr, melt spun and drawn with the spinneret arrangement as shown in Fig. 10, the cross-sectional shape is cross-shaped as shown in Fig. 8, and the flatness is 2.5 (7) 100 d/2 f (7) The drawn yarn 8F1 Created. After immersing 10 single yarns of this yarn in a free state in Sumoto for 1 minute, the appearance of crimp was observed.
The average number of crimps per 0 cm was 4.8.

In addition, the same polybutene ethylene phthalate was melted at a temperature of 266°C, a temperature of 40"O1, and an air flow rate of 70mg/hr.
The drawn yarn 8F2 was melt-spun and drawn with the spindle arrangement as shown in FIG.
It was created. When 10 single yarns of this yarn were treated with water in the same manner as above, the average number of crimp per 10 cm was o and i.

Next, polyethylene terephthalate having a molecular weight of 15,000 and containing 0.02204 titanium oxide was melt-spun and drawn to produce drawn yarns 75d/72f with round cross sections, which were subjected to Panlon processing. This thread is called WFI.

One yarn of 8F1 and two yarns of WFI were combined and twisted at 80 times/m to obtain pile yarn PFI. Also one 8F2 and WF
Two pieces of I were combined and twisted in the same manner to obtain pile yarn PF2.

When warping these pile systems, 2 PFI, 10 PH1, 4 PF 1, 80 PH1, 2 PFI, 10 PH1, 4 PFI, PH
20 pieces of 1, 1 piece of PFI, and 15 pieces of PH1 were warped in this order and wound into a beam to create 14 identical beams.These beams were then put on a regular pile heavy pile loom to obtain a cut pile fabric OPI.

For both the warp and weft, polyethylene terephthalate spun yarn with a count of 60 was used as the ground yarn. The cut length of the pile is 80mm, and the flocking density of one pile is 100 points/cm!
And so.

The present inventors published the cut pile fabric OPI in
A napping process using centrifugal force was performed using the method disclosed in Japanese Patent No. 45788. That is, the cut pile fabric OPI is attached to a cylinder with a diameter of 1 m and rotated, the nap is raised by centrifugal force, and the processing liquid is injected into an outer container (outer cylinder) with a diameter of 1.1 m that rotates on the same axis and at the same rotation speed. did. First, the rotation speed was set to 80 rpm (centrifugal force was approximately 60 G), and after heat setting at 170°C, a 20% NaOH aqueous solution (processing liquid) at 98°C was injected as a processing liquid until the inner liquid level was 10 cm from the base fabric. It was held in that position for 26 minutes to dissolve and cut the fluff, the Panlon multifilament. Then, after quickly extracting the processing liquid, 15 containing an alkali weight loss accelerator Neocation G (manufactured by NICCA Chemical Co., Ltd.) 0.2-
'Ir NaOH aqueous solution (processing liquid B) was injected at 98°C until the inner liquid level was 26 mm from the base fabric, and from that position it was added so as to increase by 1 mm in 15 minutes, and 1 liquid B was gradually injected. The tip of the polybutylene lentiphthalate filament, which is the stinging hair, was cut and sharpened. After quickly draining the processing liquid, the alkali-treated cut pile fabric was washed with water.
