Description

Pile fabric

Technical Field

The present invention relates to a pile fabric. In particular, the present invention relates to a pile fabric having excellent bulk and texture.

Background

In recent years, reduction in the use of natural fur has been proposed for the purpose of ecological preservation, and thus there is an increasing demand for the use of pile fabrics imitating natural fur as artificial fur.

The natural fur has a voluminous feeling and at the same time has a unique hand feeling of being soft to the touch of the surface. In order to obtain a voluminous feel and a hand feel similar to those of natural furs, a great deal of research has been conducted.

In particular, there is a technique of using polyester fibers as pile in the pile portion in order to obtain a bulk feeling similar to that of natural fur in artificial fur. However, when polyester fibers are used as the pile, the curl of the pile in the pile portion cannot be sufficiently removed due to a low temperature of the polishing treatment in the manufacturing process, and the like, and a stiff feel is obtained by entanglement of the piles, and further, hair cracks are generated, and the feel and appearance are clearly distinguished from those of natural fur.

Detailed Description

Embodiments of the present invention will be described below with reference to the drawings.

Fig. 1 is a schematic cross-sectional view showing a pile fabric according to an embodiment of the present invention. The pile fabric 1 of the present embodiment includes a ground weave portion 2 and a pile portion 3, the pile portion 3 includes polyester fibers as a pile 4, wherein a root portion of the pile portion 3 is in contact with a surface of the ground weave portion 2, an average fineness of the polyester fibers in the pile portion 3 is 1 to 20dtex, a length of the pile in the pile portion 3 is 10 to 80mm, a number of crimps of the polyester fibers in the pile portion 3 is 3 to 15 pieces/inch, and a crimp width of the polyester fibers in the pile portion 3 is 0.25 to 1 mm.

Specifically, the pile fabric 1 of the present embodiment includes, for example, a ground weave portion 2 of a knitted fabric, and a raised pile portion 3 that is interlaced with a ground yarn constituting the ground weave portion 2 and rises on the surface of the ground weave portion 2.

Here, a conventional method may be used for weaving the ground weave portion 2, and for example, polyester filaments or other known materials may be used for ground yarns constituting the ground weave portion 2.

Examples of the polyester fiber contained in the standing yarn part 3 include polyethylene terephthalate fiber, polypropylene terephthalate fiber, polybutylene terephthalate fiber, and polytrimethylene terephthalate fiber, and they may be used alone or in combination. Among them, polyethylene terephthalate fibers are preferable from the viewpoint of thermal characteristics.

The polyester fibers contained in the pile part 3 may contain a copolyester of other copolymerization components, and the like. Examples of the other copolymerizable component include polycarboxylic acids such as isophthalic acid, phthalic acid, naphthalenedicarboxylic acid, terephthalic acid, trimellitic acid, pyromellitic acid, succinic acid, glutaric acid, adipic acid, suberic acid, azelaic acid, sebacic acid, and dodecanedioic acid, and derivatives thereof, dicarboxylic acids containing sulfonates such as 5-sodiosulfoisophthalic acid and dihydroxyethyl 5-sodiosulfoisophthalate, and derivatives thereof, 1, 2-propanediol, 1, 3-propanediol, 1, 4-butanediol, 1, 6-hexanediol, neopentyl glycol, 1, 4-cyclohexanedimethanol, diethylene glycol, polyethylene glycol, trimethylolpropane, pentaerythritol, 4-hydroxybenzoic acid, epsilon-caprolactone, and glycol ethers of bisphenol A.

In addition, from the viewpoint of fiber combing property, the average fineness of the polyester fiber in the raised portion 3 is preferably 1dtex or more. In the case where the average fineness of the polyester fiber is more than 20dtex, it may result in insufficient softness of touch. In the method of measuring the average fineness of the polyester fibers, ten different portions are randomly selected from the pile portion 3, and the fineness of the polyester fibers is measured to obtain an arithmetic average value.

In addition, the length of the pile in the standing hair portion 3 is preferably 10 to 80mm from the viewpoint of processability and texture. In the method of measuring the pile length, the fibers constituting the pile portion 3 are raised substantially vertically so that the hairs are aligned, the length from the root to the tip of the fibers constituting the pile is measured at ten points for each pile, and the arithmetic average value is obtained as the pile length.

The number of crimps of the polyester fiber in the pile part 3 is 3 to 15 crimps/inch, preferably 5 to 12 crimps/inch, from the viewpoint of excellent bulk and hand feeling. The number of crimps of the polyester fiber can be determined by the measuring method in the examples described later.

The crimp width of the polyester fiber in the raised portion 3 is preferably 0.25 to 1 mm. In the case where the crimp width is less than 0.25mm, the polyester fibers converge with each other to make the volume feeling insufficient. And under the condition that the curling amplitude is larger than 1mm, the polyester fiber is wound more rapidly, so that the cloth becomes a rigid touch. The crimp width of the polyester fiber can be determined by the measurement method in the examples described later.

The polyester fibers in the raised portion 3 may be formed of two or more types of polyester fibers having different average fineness. By using two or more types of polyester fibers having different average fineness in combination, the fiber combing property and touch of the pile fabric can be further improved. From the viewpoint of reliably achieving such an effect, the difference between the average fineness of the polyester fiber having the largest average fineness and the average fineness of the polyester fiber having the smallest average fineness is preferably 3dtex or more, and more preferably 5dtex or more.

In this case, "composed of … … or more types of polyester fibers" means that two or more types of polyester fibers are included in the fiber. For example, the present invention includes a case where two or more types of polyester fibers are visually distinguishable by their different cross-sectional shapes, colors, and fiber lengths, a case where a graph showing a shape having two or more peaks and including two or more types of polyester fibers having different fineness distributions when the fineness distribution of the polyester fibers in the pile fabric is measured and the graph is plotted with the fineness as the horizontal axis and the appearance frequency as the vertical axis, and a case where the graph shows a shape having only a single peak and the half-peak value of the peak is 3dtex or more, preferably 5dtex or more, and substantially includes two or more types of polyester fibers having different average fineness, and the present invention is not limited to these distinguishing methods.

In addition, when the polyester fibers in the raised portion 3 are composed of two or more types of polyester fibers having different average fineness, the larger the average fineness is, the smaller the number of crimps of the polyester fibers is preferably. By setting the number of crimps of the polyester fiber to be smaller as the average fineness is larger, a pile fabric having more excellent touch can be obtained.

In addition, when the polyester fibers in the raised portion 3 are composed of two or more types of polyester fibers having different average fineness, the larger the average fineness is, the larger the crimp width of the polyester fibers is, preferably. By setting the crimp width of the polyester fiber to be larger as the average fineness is larger, a pile fabric having more excellent touch can be obtained.

When the polyester fibers in the raised portion 3 are formed of two or more types of polyester fibers having different average fineness, the average fineness of the polyester fiber having the largest average fineness is preferably 8dtex or more, and more preferably 10dtex or more. By using a polyester fiber having a large average fineness as a part of two or more types of polyester fibers, the bulk feeling and fiber combing property of the pile fabric can be improved.

In the case where the polyester fiber is composed of two or more types of polyester fibers having different average fineness, the number of crimps, and the crimp width are obtained by measuring the two or more types of polyester fibers by the respective measurement methods, and then the arithmetic average of the measurement results is defined as the average fineness, the number of crimps, and the crimp width.

The polyester fibers in the pile portion 3 may be formed of two or more types of polyester fibers having different cross-sectional shapes. By using two or more types of polyester fibers having different cross-sectional shapes in combination, the fiber combing property and touch of the pile fabric can be improved. Such a shape may be selected from two or more arbitrary shapes such as a circular cross-sectional shape, a flat shape, a pill shape, an eyebrow shape, a Y shape, an X shape, an H shape, and a hollow shape, but is not limited thereto.

The method for producing a pile fabric of the present invention is not particularly limited as long as it can be adjusted to a conventional production method under the precondition that the pile fabric of the present invention can be obtained. In addition, the examples described below exemplify several specific production methods.

Among them, examples of methods for adjusting the number of crimps and the crimp width of the polyester fiber in the fabric include the following methods (a) to (C):

(A) adjusting heat treatment conditions before and after crimping in the raw cotton production stage and finishing conditions in the cloth production stage respectively;

(B) adjusting by adjusting the curl shape in the raw cotton production stage; and

(C) in the raw cotton production stage, a first crimp having a desired crimp shape is imparted to a drawn yarn by adjusting the shape of a gear or an embossing, temperature conditions, pressure conditions, or the like using a gear crimper, an emboss roller, or other devices, the drawn yarn is heat-set at a high temperature to memorize the shape (impart crimping step 1), a second crimp necessary for processing a fabric is imparted, the second crimp is heat-set at a temperature lower than that of imparting crimping step 1 (impart crimping step 2), the obtained raw cotton is woven into a fabric, and the fabric is then rendered into the crimp shape memorized in imparting crimping step 1 by a finishing process.

The above description is directed to one embodiment of the present invention, but the scope of the present invention is not intended to be limited thereto. The present invention may be carried out in other various embodiments, and various omissions, substitutions, and changes may be made without departing from the spirit of the present invention.

Examples

The present invention will be further described below by way of examples and comparative examples.

Method for measuring curl number

When measuring the number of crimps of the polyester fiber in the fabric, first, a tuft was randomly selected from the pile portion of the pile fabric, the root portion was sandwiched by tweezers, and the single fiber of the polyester fiber was taken out from the ground structure portion. The number of crimps of the single fiber of the taken-out polyester fiber was measured in accordance with JIS L1015: 2010 for the measurement.

That is, a dividing line with a space distance of 25mm was drawn on a glossy paper sheet with a smooth surface, wherein the space distance was usually set to 25mm, and was set to 20mm when 25mm was not tested due to short fibers. In the present invention, the fiber length may be set to 20mm or less as appropriate when the fiber length is shorter. Then, samples were collected from several portions where the curl was not damaged, the collected samples were each relaxed by 25 ± 5% with respect to the spatial distance, and both ends were fixed by adhesion with an adhesive. The samples were mounted one by one on the grips of a curl tester, the sheets were cut, and then the distance (spatial distance in mm) between the grips when an initial load (0.18mN × tex) was applied to the sample (step 1) was read, and the total number of curls was counted (the number of all peaks and valleys was counted and then divided by two), and the number of curls per 25mm was converted (the average of twenty samples remained one digit after the decimal point).

In examples 3 to 6 and comparative examples 2 and 4, the number of crimps and the crimp width were adjusted by the method (C) described above. In this case, the number of crimps in the raw cotton stage (crimping step 1) is determined by using raw cotton in crimping step 1 in accordance with JIS L1015: 2010 for the measurement.

Curl width measuring method

The crimp width of the polyester fiber in the fabric was measured by the following method.

That is, in the above-described method for measuring the number of curls, in the state of step 1, the polyester fiber was photographed from the direction perpendicular to the paper sheet, and a photograph of the polyester fiber was obtained.

Next, a method for measuring the curl width will be described based on fig. 2 schematically showing the state of the photograph.

First, the polyester fiber 5 is connected to two intersections 7 of the upper and lower dividing lines 6 to form a first straight line 8. Next, in left and right portions on the paper surface of the first straight line 8, a second straight line 9 is drawn which is parallel to the first straight line 8 and is farthest from the first straight line 8 and is in contact with the polyester fiber 5. Finally, the distance between the two second straight lines 9 was measured as the curl width (arithmetic mean of twenty measurements).

In examples 3 to 6 and comparative examples 2 and 4, the number of crimps and the crimp width were adjusted by the method (C) described above. In this case, the curl width at the raw cotton stage (imparting curl step 1) is measured by the above-described method using raw cotton in imparting curl step 1.

Hand feeling evaluation method

The hand was evaluated by sensory evaluation, based on the following criteria:

it: extremely soft and smooth hand.

Very good: soft and smooth hand.

O: although slightly rough, can be used as a product with a certain degree of hand feel.

X: a rough feel and a strong hand feel.

Method for measuring volume sensation

The bulkiness was evaluated by comparing the pile fabrics produced in examples and comparative examples from the viewpoints of the dense appearance and the bulky tactile sensation, and the evaluation criteria were as follows:

and (3) excellent: the feeling of compactness in appearance was very good, and the feeling of bulkiness was also very good.

Good: the appearance is dense, and the touch sense is bulky.

Difference: the feeling of compactness in appearance and touch bulkiness were also poor.
