Description

Blended filling cotton

The application is a divisional application with the application number of 201810009919.5, the application date of 2018, 1 month and 5 days and the invention name of 'blend filling cotton'.

Technical Field

The present invention relates to blended filled cotton which can be used as a filling material for down coats, down jackets, quilts, pillows, and the like.

Background

Due to light weight and good heat preservation, the down feather is widely used as a filling material for cold-proof clothes such as down jackets and down jackets, and cold-proof bedding such as down bedding and mattress. However, since down is a natural material derived from goose feathers, it is difficult to mass-produce. In addition, down has become increasingly difficult to obtain in recent years from the standpoint of protecting animals.

On the other hand, as an alternative to down, there has been developed a cotton wool (fiber ball) which is made of chemical fibers and has a hand feeling similar to down (patent documents 1 and 2). Further, a bedding using such granular cotton has been proposed (patent document 3). Polyester fibers are mainly used as the raw material fibers.

However, since conventional granular cotton is composed of a single fiber, it is difficult to impart various functions, such as antibacterial, deodorizing, antistatic, and heat-generating functions.

In addition to granular cotton, nonwoven fabric sheets such as needle punched sheets, chemical adhesive sheets, and thermal adhesive sheets, and net-like sheets (crushed cotton) are also used for clothing and bedding, but since they are composed of a single fiber as in granular cotton, it is difficult to uniformly impart various functions.

Detailed Description

The blend wadding of one embodiment of the present invention is a granulated cotton (fiber ball), a nonwoven fabric sheet or a net sheet containing a main fiber and a functional fiber.

Examples of the main fiber include polyester fiber, polyolefin fiber, rayon fiber, polyamide fiber, and acrylonitrile fiber, and among them, polyester fiber having high elasticity and flexibility similar to feathers is preferably used, and specifically, PET fiber, PTT fiber, and the like are preferably used.

The main fiber may have a fiber diameter of 2 to 10dtex and a fiber length of 15 to 60 mm.

The functional fiber is not particularly limited, and various commercially available functional fibers can be used, and examples thereof include chemical fibers having antibacterial, deodorizing, antistatic, moisture-absorbing, moisture-permeable, heat-insulating, heat-generating, heat-storing, light-energy-generating, and heat-retaining functions. One kind or a mixture of two or more kinds of such functional fibers can be used. Further, the fibers may have two or more functions, such as moisture-absorbing and heat-generating fibers.

As the heat-generating fiber, for example, acrylic fibers of heat-absorbing cotton may be used such as "エクス (registered trademark)" produced by eastern cottonwool, or "サンバーナー (registered trademark)" produced by imperial corporation, and other compound fibers may be used such as "Topthermo (registered trademark)" produced by asahi chemical corporation, or "テンセル (registered trademark)" or "モダール (registered trademark)" produced by lanugo corporation.

Examples of the fibers having moisture absorption and scattering properties, moisture control properties, antibacterial properties, and mold resistance include "モスファイン (registered trademark)", "セルファイン S (registered trademark)" (both acrylic fibers) manufactured by tokyo corporation.

Examples of the deodorizing fibers include "モスファイン (registered trademark)" (acrylic fibers) manufactured by Toyobo Co., Ltd. Examples of the fiber having antibacterial and deodorant properties include "エアクリア (registered trademark)" manufactured by Toyobo Co., Ltd.

Examples of the heat-generating and heat-accumulating fiber include "ソーラータッチ (registered trademark)" (rayon) manufactured by Omikenshi corporation.

Examples of the fibers having bactericidal, deodorant and antistatic properties include "シルベルン ZAG (registered trademark)" (silver ion fibers) manufactured by Nippon Kagaku Kogyo Co., Ltd.

Examples of the fiber having heat retaining property include "セラム (registered trademark)" (infrared radiation type acrylic fiber) manufactured by Exlan, japan, and "ウォーマル (registered trademark)" (ceramic blend cotton) manufactured by imperial.

Examples of the fiber having antibacterial and deodorant properties include "エコピュアー (registered trademark)" (weakly acidic polyester material) manufactured by imperial corporation and "フィールフレッシュ (registered trademark)" (acrylate-based material) manufactured by eastern ocean textile corporation.

Examples of the heat insulating fiber include "エアロ (registered trademark)" manufactured by TEIJIN front corporation.

The functional fiber used may have a fiber diameter of 1.1 to 11dtex (1 to 10d) and a fiber length of 10 to 60 mm.

The specific gravities of the main fiber and the functional fiber may be substantially the same, and the specific gravity of the functional fiber is preferably within ± 10% with respect to the specific gravity of the main fiber. The fiber diameter and the fiber length may be substantially the same, and the fiber diameter and the fiber length of the functional fiber are preferably within a range of ± 10% with respect to the fiber diameter and the fiber length of the main fiber. Thus, the two fibers can be uniformly mixed, and a filling cotton having a small degree of mixing ratio deviation can be obtained.

The main fibers and the functional fibers may be the same type of fibers or different types of fibers, but the same type of fibers is preferable. The same type of fibers refers to, for example, a case where both fibers are polyester fibers.

The mixing ratio of the main fibers and the functional fibers, that is, the mixing ratio (mixing rate), is 50 mass% or more, preferably 60 mass% or more, and preferably 95 mass% or less of the main fibers. Therefore, the mixing ratio of the functional fibers is preferably 50 mass% or less, more preferably 40 mass% or less, and more preferably 5 mass% or more.

The main fibers and the functional fibers are not limited to only one type of fibers, and two or more types of fibers may be used within the range of the mixing ratio of the main fibers and the functional fibers. For example, as the functional fiber, an antibacterial fiber and a hygroscopic heating fiber may be used at the same time, and an antistatic fiber may be further combined therein. Thus, various functions of the wadding can be provided according to the application.

The form of the blended wadding of the present invention includes granular cotton, nonwoven fabric sheets, and net-like sheets (crushed cotton). Examples of the nonwoven fabric sheet include: a sheet obtained by bonding fibers to each other by a resin; needle punched sheets, which are realized by needle punching (a method of interlacing fibers with each other with needles), and the like. A nonwoven fabric sheet realized by a spunlace method (a method of interlacing fibers with each other by replacing needles with water streams) is also included in the category of a needled sheet.

Next, an example of a method for producing blended particulate cotton according to an embodiment of the blended cotton wadding of the present invention is shown in fig. 1(a) to 1 (c). Fig. 1(a) to 1(c) show a process for producing blended granular cotton. The following description is made in order.

(1) Opening step (FIG. 1(a))

The raw fibers are fed to a carding machine 2 through a feed curtain (feed curtain) 10, and are fluffed so that the fibers are aligned in parallel to produce a knitted fabric (web) (a fiber layer having a length and a width). The knitted fabric is stored in the open-end storage 4 by a cotton feeding mechanism 30 (a blower or the like). The process is carried out separately for the main fiber and the functional fiber.

(2) Blending step (FIG. 1(b))

First, predetermined amounts of the main fibers and the functional fibers, which have been previously opened and measured, are fed to the storage 5 by the cotton feeding mechanism 31 (such as a blower). In the cotton storage 5, the main fibers and the functional fibers are stirred and mixed by an air blower not shown. This can provide blended cotton in which the main fiber and the functional fiber are uniformly mixed, and can reduce the variation in the mixing ratio. The blended cotton is sucked and discharged from the cotton storage 5 in the transverse direction. That is, a suction port 8 is provided on a side surface of the hopper 5, and the suction port 8 has an opening that extends from the bottom to the top of the hopper 5. Therefore, the cellucotton can be uniformly sucked from the side surface of the cotton storage 5.

The cotton material sucked from the cotton storage 5 is transferred to the blended cotton storage 9 by a cotton feeding mechanism not shown, and temporarily stored.

(3) Process for producing granulated Cotton (FIG. 1(c))

The cotton material taken out from the blended cotton storage 9 is laid on the feeding curtain 12, conveyed to the ball forming mill 20 by the cotton feeding mechanism 32 (such as an air blower), granular cotton is produced by the ball forming mill 20, and the obtained granular cotton-filled cotton is conveyed to the storage 21 to be stored. Examples of the ball forming mill 20 to be used include ball forming mills manufactured by HAI JIN machine corporation and Changsh HITEC machine corporation, but there is no limitation to these machines as long as they are suitable for producing granulated cotton.

Further, the cotton material sucked from the cotton hopper 5 may be directly supplied to the ball forming mill 20 without providing the cotton blend storage 9.

The diameter of the obtained blended granular cotton is 1-10 mm, preferably about 5-8 mm. The dispersion of the mixing ratio (mixing rate) of the main fiber and the functional fiber constituting the blended granular cotton is 10 mass% or less, and preferably 5 mass% or less. The dispersion of the mixing ratio can be obtained by the following numerical expression.

Maximum-minimum mixing ratio as dispersion of mixing ratio

If the dispersion of the mixing ratio of the main fibers to the functional fibers exceeds 10 mass%, the function of the functional fibers cannot be sufficiently realized. In addition, since many functional fibers are sold at a high price, it is desirable to design a uniform mixing ratio with a small dispersion so as to achieve a sufficient effect with a small mixing ratio.

The maximum mixing ratio and the minimum mixing ratio are determined by determining the respective mixing ratios of the plurality of blended waddings sampled arbitrarily, and determining the maximum value and the minimum value thereof.

The mixing ratio can be determined by, for example, the unwinding method or the dissolution method (JIS L1030) described in examples described later.

The dispersion of the mixing ratio is converged to a range of 10 mass%, which is achieved mainly by the above-mentioned manufacturing process. However, it is impossible to obtain granular cotton with a uniform mixing ratio by merely mixing and blending an open-end cotton material composed of a plurality of fibers and forming the resulting cotton material into granular cotton.

In addition, when three or more kinds of fibers are used as the raw material fibers instead of two kinds, the maximum mixing ratio and the minimum mixing ratio of each fiber in the obtained blended wadding can be determined in the same manner, and the dispersion of the mixing ratio can be determined from the difference between the maximum mixing ratio and the minimum mixing ratio.

Fig. 2(a), 2(b), and 2(c) show an example of a method for producing a nonwoven fabric sheet according to another embodiment of the blend wadding of the present invention. Fig. 2(a) shows a process for producing a blend wadding. Fig. 2(b) shows a method of stacking the mesh sheets after opening. Fig. 2(c) shows a part of the manufacturing process of the blended wadding by the needle punching method. The following description is made in detail.

As shown in fig. 2(a), the main fibers and the functional fibers that have been opened in the opening machine (not shown) are conveyed to the weighing machine 40, and a predetermined amount is measured and conveyed to the cotton storage 51. The hopper 51 has substantially the same structure and function as the hopper 5, and uniformly stirs and mixes the main fibers and the functional fibers, which are respectively fed by the air blowing mechanism.

Then, the cotton is conveyed from the cotton bank 51 to the cotton feed blower 41 through the suction port 18, and a predetermined amount of the cotton blend is supplied from the cotton feed blower 41 to each of the 3

roller carders

42, 43, and 44. The blended cotton was fluffed by

roller cards

42, 43, and 44 to align fibers in parallel, thereby producing webs W1, W2, and W3. The webs W1, W2, W3 are stacked on the feeding curtain 45. Fig. 2(b) is a side view of the state in which the webs W1, W2, and W3 are stacked. As shown in the drawing, the intermediate web W2 is fed in the width direction of the feeding curtain 45 (i.e., in the direction perpendicular to the feeding direction of the web), and is folded back at the side end of the feeding curtain 45 and partially overlapped. Therefore, the fiber direction of the web W2 coincides with the sheet width direction. This can improve the sheet strength in the sheet width direction. The mesh sheets W1, W3 are aligned with the longitudinal direction of the sheet (the feeding direction of the feeding curtain 45).

Further, the webs W1, W2, W3 may be stacked in the same direction (for example, the longitudinal direction or the width direction orthogonal to the longitudinal direction) as necessary.

The blend cotton layered in the form of a sheet on the feed curtain 45 as described above is continuously conveyed to the resin sprayer 46, the resin is sprayed in the form of a mist by the resin sprayer 46, and then dried by the dryer 47, and then wound up to obtain the chemically bonded nonwoven fabric sheet 48. It can also be: the sprayer 46 was replaced with a dipping device, and the blended cotton was dipped in the resin solution and then dried.

The resin used is mainly a urethane resin-based binder, and the spraying amount of the resin is 0.1 to 2.0 parts by mass, preferably 0.5 to 1.0 part by mass, per 100 parts by mass of the blended cotton.

The needle-punching-based process for producing the cotton wadding of blended yarn is the same as the chemical-bonding-based process for producing the cotton wadding of blended yarn shown in fig. 2(a) and 2(b) before the process of laminating the webs W1, W2, and W3 in a sheet form, and therefore, the detailed description thereof will be omitted. As shown in fig. 2(c), the union wadding superimposed on the feed curtain 45 in a sheet form is continuously fed to a needle loom 49, and the needles moving up and down and penetrating from the sheet mechanically interweave the fibers with each other, thereby obtaining a nonwoven sheet 48'.

The dispersion of the mixing ratio of the main fibers and the functional fibers constituting the nonwoven fabric sheets 48 and 48' is 10 mass% or less, preferably 5 mass% or less. The mixing ratio can be determined in the same manner as in the above-described granular cotton. The sampling for determining the mixing ratio may be performed within 1 chip, or may be performed between a plurality of chips.

On the other hand, if the method shown in fig. 2(a), 2(b), 2(c) is replaced by the method shown in fig. 3, that is, as shown in fig. 3, the main fibers and the functional fibers are supplied to the

roller cards

42, 43, 44, respectively, and the resulting webs W1 ', W2' are fed to the roller cards ³ And superposed on the feeding curtain 45 and made into the nonwoven fabric sheet 50 by the needle loom 49, in which case the dispersion of the mixing ratio of the main fibers and the functional fibers constituting the obtained nonwoven fabric sheet 50 is hardly controlled within 10 mass%. This is true not only for needle punching but also for chemical bonding.

The form of the blended wadding of the present invention may be not only a granular cotton and a nonwoven fabric sheet but also a net-like sheet. In fig. 2(a), the web sheet is obtained by opening the main fibers and the functional fibers uniformly mixed and stirred in the hopper 51 by the

roller carding machines

42, 43, and 44 to obtain webs W1, W2, and W3, and superposing the webs W1, W2, and W3 on the feeding curtain 45. The superposition of the webs W1, W2, W3 may be of the configuration shown in fig. 2(b), but is not limited thereto. The number of the roller cards is not limited to 3, and may be 2 or more.

The blended filling cotton obtained by the embodiment of the invention has uniform performance, so the blended filling cotton is preferably suitable to be used as a filling cotton material for garments such as jackets for keeping out cold, coats and the like as a substitute of down; bedding such as bedding and pillow; and seat cushions, back cushions, and the like.

In this case, since the blended wadding contains functional fibers in addition to the main fibers, it is possible to add functions such as antibacterial, deodorizing, antistatic, moisture-absorbing, moisture-permeable, heat-insulating, heat-generating, heat-storing, light-energy heat-generating, and heat-insulating functions, and therefore it is possible to provide a wadding material suitable for various uses and purposes.

[ examples ] A method for producing a compound

The present invention will be specifically described below with reference to examples and comparative examples, but the present invention is not limited to the following examples.

(example 1)

As the main fiber, a polyester fiber (PET fiber) having a fiber diameter of 2.2dtex and a fiber length of 32mm was used. As the secondary fiber, a black-dyed polyester fiber (PET fiber) having a fiber diameter of 2.2dtex and a fiber length of 32mm was used. Secondary fibers are used as a substitute for the functional fibers. The fibers were each individually carded by a carding machine (DK-903 manufactured by Trutzschler Co.). In addition, the polyester fiber dyed black is used in order to easily visually recognize the mixture of the polyester fibers.

250g of the opened polyester fibers were uniformly spread on a feeding curtain. Then, 250g of the polyester fiber dyed black after opening was placed on the above layer of the polyester fiber. Then, the cotton is put into a cotton storage 5 (inner volume: 5 m) as shown in FIG. 1(b) from the top by a blower ³ ) In (1). This operation is repeated below, and the blended fibers of the polyester fibers and the black-dyed polyester fibers are stored in the cotton storage 5 and mixed by stirring.

Subsequently, the fibers were sucked from the cotton bank 5 in the transverse direction, and blended cotton composed of 50 mass% of polyester fibers and 50 mass% of the polyester fibers dyed black after opening was obtained. The blended cotton was fed to a pelletizer 20 to obtain a blended filled cotton having a diameter of 5 mm.

Next, 2g of each of the blended waddings was sampled from any six places (n ═ 6), and the blend ratio was calculated by the unwinding method (JIS L1030). As a result, the maximum mixing ratio was 50.5% and the minimum mixing ratio was 49.5%, and therefore, the dispersion of the mixing ratio was in the range of 1%. Fig. 4 is an enlarged photograph of the resulting blend wadding.

Comparative example 1

A blended cotton wadding was obtained in the same manner as in example 1, except that blended cotton was obtained by mixing 50 mass% of polyester fiber and 50 mass% of black-dyed polyester fiber without opening and using the cotton storage 5. The dispersion of the mixing ratio was determined in the same manner as in example 1 and was 60%. An enlarged photograph of the resulting blended filled cotton is shown in fig. 5.

As shown in fig. 5, the blend wadding obtained in comparative example 1 was poor in uniformity in which the black-dyed polyester fiber clumps were dispersed throughout the entire granular cotton, whereas the blend wadding obtained in example 1 shown in fig. 4 was obtained in which the black-dyed polyester fiber and the polyester fiber as the main fiber were uniformly mixed.

(example 2)

425g of the opened polyester fibers were uniformly spread on a feeding sheet, 75g of the opened moisture-absorbing and heat-generating fibers (acrylic ester fibers) were uniformly divided into nine parts or more and placed on the polyester fiber layer at equal intervals, and the divided fibers were fed from the top into a cotton storage 5 (inner volume: 5 m) by a blower ³ ) Except for the above, blended wadding having a diameter of 5mm and comprising 85 mass% of polyester fiber and 15 mass% of hygroscopic heat-generating fiber was obtained in the same manner as in example 1. In addition, the reason why 75g of the absorbent heating fibers are uniformly divided into 9 parts or more is to prevent the fibers from being displaced.

Regarding the dispersion of the mixing ratio, 2g of the granular cotton was sampled from any six places (n ═ 6), and the mixing ratio was determined in the same manner as in example 1. The results are shown in table 1.

(Table 1)

According to table 1, the blend ratio dispersion of the blended filled cotton obtained by example 2 was in the range of 1%.

(example 3)

A blend wadding made of a needle-punched nonwoven fabric sheet was produced by the production process shown in fig. 2 (c).

As the main fiber, a polyester fiber (PET fiber) having a fiber diameter of 2.2dtex and a fiber length of 32mm was used. As the functional fiber, "テンセル (registered trademark)" made by Rakawa Kagaku having a fiber diameter of 2.2dtex and a fiber length of 32mm was used.

First, with the main fiber: secondary fiber 80: the main fibers and the functional fibers after opening were measured at 20 (mass ratio) so that the weight of the sheet was 60g/m ² Then, it was put into a cotton storage 5 (internal volume: 5 m) ³ ) And stirred and mixed. The wool is opened by 3

roller carding machines

42, 43 and 44,webs W1, W2, and W3 were obtained, and were superposed as shown in fig. 2(b), and continuously fed to a needle loom 49, thereby obtaining a nonwoven fabric sheet 48' having a width of 1.5 m.

Comparative example 2

As shown in fig. 3, a nonwoven fabric sheet 50 was produced by a needle loom 49 in the same manner as in example 3, except that the main fibers and the functional fibers were supplied to

roller cards

42, 43, and 44, respectively, and the resulting webs W1 ', W2 ', and W3 ' were superposed on a feeding curtain 45.

The blend ratio of the blend wadding of the nonwoven fabric sheets obtained in example 3 and comparative example 2 was measured. That is, the mixture ratio was measured in the same manner as in example 1 at the sampling points 3 (the position 10cm from both side ends and the central position thereof) in the width direction at the positions 1m away in the longitudinal direction of the nonwoven fabric sheet, and at the sampling points 6 in total. The results are shown in table 2 below.

(Table 2)

(mass%) (polyester (80%)/テンセル (20%))

The present invention is not limited to the above-described embodiments, and various changes and modifications can be made within the scope of the claims. For example, in the above embodiment, the description has been given of the blend wadding of the main fiber (polyester fiber or the like) and the functional fiber, but the blend wadding is not limited to the combination of the main fiber and the functional fiber, and may be a blend wadding in which different types of fibers are combined with each other. For example, combinations of fibers not classified into functional fibers, combinations of functional fibers, and the like can be cited. Thus, a blended wadding having functions of the respective fibers can be obtained. The combinations are not limited to two, and may be three or more. The type of the fiber used is not particularly limited.
