長いと開繊性や製綿性が悪くなる傾向がある。The fibers constituting the flame-retardant nonwoven fabric according to the present invention have a fineness of 1.5 to 30 deniers, preferably 3 to 20 deniers, and more preferably 6 to 18 densities in order to give a moderate bulkiness and a soft texture. It is denier and the fiber length is 10 to 100 mm, preferably 50 to 80 mm, and polyester short fibers are particularly suitable. Fineness is 1.
If it is less than 5 denier, the bulk is difficult to appear, and if it is 30 denier or more, the texture becomes hard. When the fiber length is shorter than 10 mm, the entanglement between the fibers is poor, and it is difficult to form the structure. When the fiber length is longer than 100 mm, the opening property and the cotton-forming property tend to deteriorate.

A crimped one is more preferred. The number of crimps is preferably 5 to 30 / inch, more preferably 10 to 20 / inch. The degree of crimp is preferably from 5 to 40%, more preferably from 10 to 35%. If the number of crimps is 5 / inch or less, and the degree of crimp is 5% or less, uniform spreading is not performed during the spreading process, and spots are likely to occur on the spread web. If the number of crimps is 30 pieces / inch or more and the degree of crimp is 40% or more, the texture of the product after opening the card tends to be poor.

Preferably, the content is 20% by weight or more. If it is less than 5% by weight, the texture becomes hard, and the effect of feather-like is difficult to be obtained.
The purpose of the modified acrylic fiber is to impart flame retardancy, and the content is not particularly limited as long as the flame retardancy passes.

しくない。In the production method for making the thickness 20 mm or more, first, the fiber is made into a web by a defibrating machine (card), and the fiber is entangled by a needle punch. At this time, if the desired thickness is not obtained, a plurality of webs before applying the web or the needle punch are overlapped,
Further, they are entangled by a needle punch. As described above, the thickness is 20 for bed pad etc.
A thickness of 20 mm or less is sufficient, but when used as a batting of a sheet or a core of a mattress, a problem such as a feeling of flooring tends to occur at a thickness of 20 mm or less. Although it is possible to make the thickness larger than 100 mm, it is not preferable in view of cost and advantages of the final product.

/ Cm 3 . If it is less than 0.02 g / cm 3 , the resilience is weak, and the feeling of flooring at the time of use becomes a problem.
If it is 3 or more, the structure is hard and it is difficult to make it entangled, which causes problems such as needle breakage.

効果が発揮される。When a polyester-based flame-retardant fiber is generally burned, the fiber is melted, the burning point drops, and the flame is hardly spread. As a result, the structure using the fiber is hardly burned. However, in a structure in which the fiber and the silicon-processed fiber are mixed, the flame spreads along the silicon before the polyester fiber melts and falls, and the flame-retardant effect is lost. On the other hand, the modified acrylic fiber used in the present invention is a highly crosslinked product, and is carbonized without being melted even when burned, so that the flame is extremely difficult to spread and spread, and the structure is obtained even when silicon-treated fiber is mixed. The flame retardant effect as a body is exhibited.
