Lace products for bedding

The present invention relates to a lace product for bedding which is used in direct contact with a human body such as a pillow cover, a sheet, a bed cover, a chair cover, or the like, or in indirect contact with thin clothes. Background art

Conventional bedding products used in direct contact with the human body, such as pillowcases and sheets, or in indirect contact with thin clothing, are made of cloth (woven fabric without watermarks). Covers that indirectly touch the human body, such as bed covers and chair covers, through clothing are made of cloth or lace (woven or knitted fabric with an openwork pattern).

The human body emits 1.5 to 2.0 liters of water per day. Therefore, pillowcases, sheets, bed covers, chair covers, etc., which are used in direct or indirect contact with the human body, absorb the above-mentioned moisture emanating from the human body for comfort and hygiene during use. It is desirable to have the function of releasing to the outside air, that is, to have moisture permeability (breathability) o

For this reason, in the past, sheets, pillow covers, bed covers, chair covers, and the like have been made of cloth having good air permeability and made of fibers having good hygroscopicity. Natural fibers, such as cotton and silk, have good hygroscopic properties.However, conventional products are made of cloth, so they have a certain degree of hygroscopicity but not very good. After a short period of use, excess moisture remains in the sheets and covers, causing the heat to stay moist and moist, resulting in poor sleeping comfort and poor usability.

For this reason, pillows containing activated charcoal, black husk, etc. are widely used in order to improve the hygroscopicity and moisture release of pillows in pursuit of comfort during use. When wearing a pillow, a cloth pillow cover is usually used to prevent stains and alleviate pain. In addition, in many cases, mats having various shapes of unevenness are used to improve the hygroscopicity and moisture release of the futon in order to improve comfort at bedtime. Usually, cloth sheets are laid on the top of the mat to prevent dirt and wear.

Therefore, a cloth pillow cover or sheet is interposed between the surface of the pillow, mat or mattress and the human body, and the cloth surface with poor air permeability comes into contact with the surface of the human body. The water emanating from the water is absorbed by the pillowcases and sheets, but within a relatively short period of time, the water absorption decreases and moisture remains, making it difficult to sleep due to low moisture release and heat retention. Frequent turning over, falling off the pillows, and removing the comforter are preventing a good night's sleep. Also, cloth pillowcases and sheets are generally thin, and their use makes the contact surfaces with the human body wear quickly and vulnerable, so they cannot withstand repeated washing. That is, the durability is poor.

Silk is known to be excellent in hygroscopicity and moisture release. However, in order to make a pillow cover or sheets made of abrasion-resistant silk cloth, it is necessary to use expensive silk thread, which is not only a momentum expensive product, but also the contact of the cloth with human body due to weight load. Since the surface is worn and the yarn is easily broken or fluffed, the life is short and uneconomical.

In addition, lace pillowcases and sheets may be used to ensure air permeability.However, conventional lace is a machine lace using a high-speed lace machine aimed at low-cost mass production. It is not practical because the tissue is so hard that it leaves a mark on the skin where the watermark or the knot of the thread is in contact, leaving uncomfortable discomfort during prolonged sleep. . Even if a soft-textured lace is used, the conventional mechanical lace has a drawback of poor durability, as in the case of fabric, because if any thread breaks, the other part will be frayed in a potato vine style .

As described above, conventionally, there is no cover that covers the part of the bedding that comes into contact with the human body, which does not have good air permeability and moisture release, and is moist with the warmth of the body. This makes them uncomfortable and uncomfortable to use, especially in the case of sheets, which can cause bedsores in people who sleep a long time, such as sick or disabled. However, until now, there was no product that could fundamentally prevent this.

In the future, as the number of people requiring care increases as the aging society progresses, There is a strong demand for the emergence of a bedding cover that has a breathability, a hygroscopic property and a moisture release property to provide a comfortable sleeping comfort or a comfortable use and that can prevent floor displacement.

The present invention has been made to meet the above demand. Disclosure of the invention

In order to solve the above problems, the lace product for bedding of the present invention is in a state in which the pillow cover, sheets or sheets cover, bed cover, chair cover, etc. are in direct contact with the human body or in thin clothes. It is made of a torsion lace with an openwork pattern of an arbitrary pattern, formed by a torsion lace machine by applying a tension of 0.8 Nm or less to silk thread. It is characterized by the fact that

With the above configuration, pillow covers, sheets or sheets force bars, bed covers, chair covers, etc., made of tonal lace have a soft lace structure, good texture (feel), and high air permeability. It has excellent water absorbency and moisture release, strong pulling force, no fraying, and excellent durability. BEST MODE FOR CARRYING OUT THE INVENTION

Next, an embodiment of the present invention will be described.

The lace product for bedding according to the present invention is made of torsion lace, and the torsion lace is made using a known torsion lace machine. The toy race machine raises a plurality of bobbins on a horizontal arm, forms a set of bobbins, and places a number of bobbins along the circumference of the upper surface of the table, centering on the center of the arm. Are arranged to be swingable about a vertical axis. While swinging each set of bobbin sets in the predetermined direction in the circumferential direction of the table in the predetermined order around the vertical axis to the right or left, pull out the yarn from each bobbin while applying tension to the set, and pull out the table. A known knitted portion provided above the center of the table is drawn to a known braided portion arranged along the circumference above the center of the table, and the braided yarn is formed by braiding the yarns by a known method. It is configured to draw in. Then, to determine the design of the watermark pattern, for example, read the punch hole pattern of the punch card By reading the bobbin set corresponding to the punched hole with a known selecting mechanism and determining the swinging direction, a narrow band-shaped transition lace having a watermark pattern of a predetermined pattern is read. The thread is drawn out from a large number of bobbins as described above when the torsion race used for making the bedding lace product of the present invention is made. When the yarn is pulled out from the bobbin, the yarn is pulled out from the bobbin, for example, by pressing a panel or the like against the bobbin to apply rotational friction. The following tensions are added.

In a typical torsion lace machine, the tension applied to the yarn is about 1.0-1.2 N * m. As a result, the resulting race had a hard structure due to the high tension of the yarn.

On the other hand, in the present invention, the tension added to the yarn in the yarn assembling step is reduced to 0.8 N · m or less, preferably 0.4 to 0.5 N · m. As a result, the tension of each fiber of the braided yarn is low and there is room, so that the resulting torsion lace is soft as a whole.

Also, since the braided yarn is formed and then knitted to produce a lace, the lace has the following characteristics: it has good air permeability, is soft and soft, and has very high tensile strength. Also, because the thread is braided, no fraying occurs even if some of the thread breaks. Therefore, a highly durable race having excellent wear resistance can be obtained.

The required number of small width races can be combined in the required number of horizontal and Z or vertical directions to make pillow covers, sheets or sheets covers, bed covers or chair covers of appropriate width and length. it can. Of course, if a large torsion lace machine is used, it is possible to make one pillow cover, sheet or sheet force bar, bed cover or chair cover, etc. directly from the torsion lace machine.

The single maximum open area of the watermark pattern of the above-mentioned lace is that the pillow cover, sheets or sheets cover, bed cover or chair cover, etc. made with this lace, even if it is part of the human body, pillows or mattresses Or, the size is such that it does not come into contact with a chair or the like, for example, about 10 cm ² or less. Since the toy lace according to the present invention uses silk as a material, it has a water absorbency 1.3 to 1.5 times that of cotton, and has a moisture releasing property comparable to cotton. Therefore, pillowcases, sheets or sheets covers, bed covers, chair covers, etc. made using such a piece of lace are excellent in hygroscopicity and high in the rate of moisture release due to their material properties. However, no extra moisture remains in them. Also, as a structural characteristic, it has excellent ventilation. Therefore, in the case of pillow covers, sheets, and bed covers, there is no accumulation of heat between the pillows, futons or beds and the human body, and the skin feels good and comfortable. Therefore, good sleep and good sleep can be obtained.

Further, the torsion lace according to the present invention is excellent in water absorbency, moisture release and ventilation, and has a tissue structure having a watermark pattern with a void area of about 10 cm or less, so that a person lying on the Since a proper stimulation and acupressure effect is given to the skin according to its weight, a blood circulation promoting effect, in particular, a skin blood circulation promoting effect and a body temperature increasing effect based on the blood circulation promoting effect can be obtained. Therefore, it is worth noting that the effect of effectively preventing bedsores in long-term lying patients can be obtained. Furthermore, it does not adhere to the human body surface and is excellent in hygroscopicity, moisture release and ventilation, so that it can not only achieve a remarkable health promotion effect but also prevent skin diseases, for example, the onset of bed sore mentioned above or treat it early. In addition to being expected to be highly effective, it has been recognized that it has an excellent therapeutic effect on atopic dermatitis, athlete's foot, and the like.

In addition, since the lace structure is soft, unlike ordinary laces, there is no discomfort due to thread knots digging into the skin, and it is soft and conforms to irregularities or curved surfaces of the human body, deforming, good.

From this viewpoint, it is expected that the same operation and effect as described above can be obtained even when clothes such as pajamas, nightgowns, and negligee that are directly applied to the skin of a person are made using the tough race according to the present invention. Is done.

Furthermore, the use of the torsion lace makes it extremely resistant to pulling force and does not become frayed even if some of the thread breaks, so it can withstand long-term use and repeated washing, and is durable. Are better. It can be used for a long time even as a bed cover or chair cover, which is susceptible to relatively large frictional forces.

As the silk yarn, which is a lace material, any one of one or two or more of a raw yarn, a ball yarn, a silk spun yarn, and a silk sponge yarn can be used. In facilities that do customer business such as lodging, It is desirable to use raw silk that has a glossy appearance and high-grade feel even in value, but in general households, relatively inexpensive yarn or silk yarn may be used, and the aim is to achieve a unique design effect. If you want, you can use silk yarn.

It is possible to provide glossy and colorful beddings utilizing the characteristics of silk. In addition, silk is light and has high compression elasticity, so it feels good, does not undergo permanent deformation, keeps its thickness forever, and maintains its comfort.

Furthermore, silk has a larger fiber shrinkage ratio than cotton due to a large amount of moisture absorption or water infiltration during washing, but the cover according to the present invention uses a torsion lace having a braided yarn with a low degree of tension due to the addition of a low tension. Since it is used, there is no shrinkage of the entire hippopotamus due to moisture absorption or water infiltration.

The pillow cover made of torsion lace, formed by adding low tension, has a soft tissue and a large coefficient of friction due to the presence of the watermark pattern. It can be used securely without falling off on the pillow. The sheets can be used directly laid on a mat or mattress, or used as a sheet cover on conventional sheets. The same comfort can be enjoyed when the chair cover is used not only as a furniture chair but also as a car chair cover.

As described above, the lace product for bedding according to the present invention is made by using the torsion lace formed by adding a low tension to the silk thread. It is soft, light and comfortable, and has excellent breathability, water absorption and moisture release.It is very comfortable when used in direct contact with the human body or indirect contact with thin clothing. Comfortable sleep and comfort can be provided. In addition, the stimulating effect of the tissue structure of the watermarked watermarked race or the blood circulation promoting effect based on the acupressure effect can exert not only a health promoting effect but also a preventive and therapeutic effect for skin diseases.

Also, since it is a silk torsion lace, it has high compressive elasticity and high tensile strength, so it deforms obediently according to the user's body shape, so it does not give a sense of incongruity and has excellent durability Therefore, it can withstand repeated washing.

When using one or more types of raw yarn, raw yarn, silk yarn, and silk sponge yarn, use Depending on the application or location, various grades of cover can be provided for price, appearance, quality, etc. Industrial applicability

The lace product for bedding of the present invention can be used as a pillow cover, a bed sheet, a bed cover, a bed cover, a cover for a furniture chair, and a cover for a wheelchair. It can also be applied to pajamas, nightgowns, negligees, and other clothing that is applied directly to human skin.
