Description

  The present invention relates to a highly flame retardant bedding product.

In order to prevent fire, it is preferable to impart flame retardancy to materials used in bedding products, interior products, furniture, and the like in a house. In addition, the material to which flame retardancy is imparted must not impair the comfort and hygroscopicity of bedding products and interior products.
Among bedding products and interior products, there are products that require cushioning, such as mattress pads, comforters, or pillows. In many cases, in these products, polyester fibers having excellent elasticity are used for the batting to exhibit cushioning properties. In addition, fibers such as cotton having excellent hygroscopicity and polyester having excellent durability are used for the side ground. Although various flame retardant examinations have been made for these products, most of them have been related to the flame retardant of the side land.
In order to make the fiber flame retardant, it is necessary to use a fiber containing a flame retardant such as an antimony compound or a phosphorus compound or a flame retardant fiber such as a glass fiber. Such fibers are inferior in comfort such as touch or moisture absorption. Therefore, it is desirable that the bedding having the batting is made flame retardant instead of the side cloth.

  In recent years, bedding and interior textile products have been required to have a high degree of flame retardancy. Such flame retardancy is described, for example, in a draft (hereinafter referred to as TB604) issued in October 2003 of a combustion test method Technical Bulletin 604 such as a pillow in California, USA. Here, a high degree of flame retardancy is required, for example, it does not burn even when in contact with a flame for a long time, for example, 20 seconds.

Patent Document 1 proposes a textile product for bedding using a flame retardant fiber composite that combines a highly flame retardant halogen-containing fiber to which a large amount of a flame retardant is added and other fibers such as polyester that is not flame retardant. Has been. Patent Document 1 does not disclose the use of the flame retardant fiber composite for filling. However, even when the composite of halogen-containing fiber and polyester fiber described in Patent Document 1 is used for batting, a large amount of flame retardant is required to achieve high flame retardancy, for example, flame retardancy described in TB604. It has been found necessary to use a functional halogen-containing fiber. When a large amount of halogen-containing fiber is used, the amount of polyester fiber used is reduced and the elasticity of the batting is lowered.

  Among these, the antimony compound is preferable because it reacts with a halogen atom desorbed from the modacrylic fiber at the time of combustion and produces antimony halide, thereby exhibiting extremely high flame retardancy. The antimony compound is preferably added in an amount of 6 to 50% by weight based on the modacrylic fiber. Specific examples of the modacrylic fiber to which the antimony compound is added include Kanekaron PBX manufactured by Kaneka Corporation and SEF (SEF) manufactured by Solutia, but are not limited thereto.

  Cellulosic fibers (A), polyester fibers (B), and halogen-containing fibers (C) are 10 to 40 wt% cellulose fibers (A), 50 to 80 wt% polyester fibers (B), and halogen-containing fibers. (C) 10 to 40% by weight. The specific ratio is further determined by comfort such as texture, hygroscopicity, elasticity, washing resistance and durability, degree of carbonized film formation, shape maintenance performance, and self-extinguishing speed.

  Cellulosic fiber (A) is a main component that gives the bedding product the texture and hygroscopicity of cellulosic fiber (A) and contributes to the formation of a carbonized carbon film or the maintenance of the shape of the cotton pad during combustion. When the cellulosic fiber (A) is less than 10% by weight, the cellulosic fiber (A) has insufficient texture and hygroscopicity, and the carbonization ability of the filling is insufficient. Further, if the ratio of the cellulose fiber (A) in the batting exceeds 40 weights, the elasticity of the batting is deteriorated or the fire extinguishing performance is deteriorated. Therefore, it is necessary to be 40% by weight or less.

  The polyester fiber (B) is a main component that improves the washing resistance, durability or elasticity of the bedding product. Since the polyester fiber (B) is easily melted by combustion, if its proportion exceeds 80% by weight, the proportion of the melted component in the batting increases, and the flame retardancy is insufficient. Moreover, there is no problem in flame retardancy even if the proportion of the polyester fiber (B) is less than 50% by weight. However, the proportion of polyester fiber (B) must be 50% by weight or more to give elasticity to the batting of bedding products that require elasticity such as comforters, mattress pads, padded cotton pillows, and cushions. is required.

  Halogen-containing fiber (C) is a main component that imparts self-extinguishing properties to batting, but when the proportion of halogen-containing fiber (C) exceeds 40% by weight, the texture of cellulose fiber (A), polyester fiber The elasticity of (B) cannot be sufficiently obtained, and the halogen-containing fiber (C) generates a large amount of gas that affects the human body when the bedding product is burned.

  In the batting of the present invention, it is preferable that the cellulosic fiber (A), the polyester fiber (B), the halogen-containing fiber (C) and other fibers used as necessary are sufficiently mixed. The blended cotton of the present invention may be used by being packed in a side of a predetermined shape. Alternatively, the mixed fibers can be used as a web after blending the above-mentioned fibers so as to form a nonwoven fabric. The highly flame retardant batting of the present invention is used in bedding products that require batting such as comforters, mattress pads, stuffed cotton pillows, and bedding cushions.

  As the side covering the highly flame-retardant batting of the present invention, a side consisting of cellulose fibers and / or polyester fibers generally used in bedding products and interior furniture is preferable, It is not particularly limited. In order to satisfy performances desired for bedding products and interior furniture such as texture, hygroscopicity and durability, the composition of the side fabric is 20 to 80% by weight of cellulosic fibers and 80 to 20% by weight of polyester fibers. preferable.

  Cellulosic fibers (A), polyester fibers (B), and halogen-containing fibers (C) are essential components in the highly flame-retardant filling of the present invention. The cellulosic fiber (A) has a carbonization promoting effect, and forms a stable carbonized film that is quickly carbonized and has a small shrinkage when exposed to flame. Moreover, the polyester fiber (B) can impart excellent elasticity performance to the flame-retardant bedding product of the present invention. The halogen-containing fiber (C) can improve the fire extinguishing performance of the batting.

As described above, according to the present invention, it is possible to obtain a highly flame-retardant bedding product. In addition, according to the present invention, the generation of gas affecting the human body is minimized while fully drawing out the unique texture and comfort of the materials of bedding products such as cushions, pillows, mattress pads, comforters and futons. It is possible to obtain a bedding product.
Hereinafter, the present invention will be described in more detail with reference to examples. However, the present invention is not limited to the examples.

(Manufacture of batting)
As cellulosic fiber (A), Corona R (fineness 1.7 dtex, cut length 38 mm) of Daiwabo Rayon, which is a general-purpose cellulose fiber, or Visil (Satel), a flame-retardant cellulosic fiber, is used. (Fineness 3.5 dtex, cut length 50 mm) was used. As the polyester fiber (B), Tetron R (fineness 6dtex, cut length 51mm) manufactured by Toray, which is a general-purpose polyester fiber, or Trevira CS manufactured by Trevira, which is a flame-retardant polyester fiber, is used. did. Kanekaron PBX (fineness: 2 dtex, cut length: 51 mm) manufactured by Kaneka Corporation containing an antimony compound as a flame retardant was used as the halogen-containing fiber (C). These fibers were opened with a card at a blending ratio shown in Table 1 to form a web, and the layers were formed into a batting.

(Create side land)
A spun yarn with a metric count of 34 was obtained by blending 50% by weight of cotton fiber and 50% by weight of polyester fiber. A plain weave fabric having a basis weight of 120 g / m ² was prepared from this spun yarn by a known method.

(How to make a cushion for flame retardant evaluation)
The produced filling is cut into a length of about 30.5 cm and a width of about 30.5 cm. The batting is sandwiched between fabrics (side ground) cut to about 38.1cm in length and 38.1cm in width, and a plate with a weight of 325g is placed on it, and the height of the cushion is 89mm (3.5inch) or more and 102mm (4.0inch) ) Was adjusted so as to be within the range, and four sides were closed with a cut yarn to create a flame retardant evaluation cushion.

(Flame retardance evaluation method)
The flame retardancy was carried out based on a draft (TB604) Section 2 issued in October 2004 by the combustion test method Technical Bulletin 604 in California, USA. The TB604 combustion test method in California, USA will be briefly described. In the test for pillows and cushions, the test piece is 3/4 inch below one corner of the flame retardant evaluation cushion that is leveled. A 35 mm flame is applied for 20 seconds. If the weight loss rate after 6 minutes is 25% by weight or less, it is acceptable. In Table 2, when the weight reduction rate was within 25% by weight, “◯” was given, and when it was over 25% by weight, “X” was given.
The burner tube used has an inner diameter of 6.5 mm, an outer diameter of 8 mm, and a length of 200 mm. The fuel gas is butane gas with a purity of 99% or more, the butane gas flow rate is 45 ml / min, and the height of the flame is about 35 mm.

(Elasticity evaluation method)
The elasticity evaluation was performed using the above-mentioned flame retardant evaluation cushion. The amount of batting was 1000 g / m ² . The elasticity was evaluated by visual inspection of the cushion. A flame retardant evaluation cushion that has sufficient volume as a bedding product (for example, when the same volume as a cushion using polyester fiber is used for batting) and a volume that can be used as bedding △, and inferior ones were evaluated as × (for example, when there is the same volume feeling as a cushion using rayon fibers in batting).

(Examples 1-9, Comparative Examples 1-9)
The prepared flame retardant evaluation cushion was evaluated for flame retardancy and elasticity. The results are shown in Table 2.

In Examples 1 to 9, in any case, the flame retardancy and the state of the carbonized film in the combustion test were good. Furthermore, since the polyester fiber (B) is contained in an amount of 50 to 70% by weight based on the entire batting, the elasticity necessary for bedding products such as a comforter, mattress pad, padded cotton pillow, bedding cushion, etc. is sufficiently obtained. I was able to.
In Comparative Example 1, the flame retardant polyester fiber is excellent in self-extinguishing property among the polyester fibers (B). However, since the cellulosic fiber (A) is not included, the state of the carbonized film was insufficient. For this reason, the heat | fever of the fuse | melted flame-retardant polyester-type fiber was transmitted to the inside of batting, and the fusion | melting of the flame-retardant polyester-type fiber further advanced with the heat. As a result, the weight reduction rate 6 minutes after the completion of flame contact exceeded 25% by weight, and sufficient flame retardancy could not be obtained.
In Comparative Examples 2 and 3, the halogen-containing fiber (C) is included as compared with Comparative Example 1, but since the cellulose-based fiber (A) is not included, the state of the carbonized film becomes insufficient, and the fire fighting ability of the filling is inferior. It was a thing.
In Comparative Examples 4 to 6, the flame retardancy and the state of the carbonized film were good, but the mixing ratio of the polyester fiber (B) was small, and sufficient elasticity was not obtained. Further, when the mixing ratio of the halogen-containing fiber (C) is high as in Comparative Example 6, a sufficient texture, hygroscopicity and elasticity cannot be obtained, and a large amount of gas that adversely affects the human body is generated during combustion. It becomes difficult to put it into practical use.

  The present invention relates to a flame retardant bedding product using cellulosic fibers (A), polyester fibers (B) and halogen-containing fibers (C) as batting. The bedding product of the present invention has a high degree of flame retardancy capable of preventing combustion even in a combustion test in which a large amount of the halogen-containing fiber (C) is not used, but in contact with a flame for a long time. Moreover, the elasticity which a polyester-type fiber (B) has is not impaired. Thus, it can be used industrially in the field of bedding such as cushions, pillows, mattress pads, comforters, and futons.
