The present invention relates to a padding for a mattress, and more particularly to a padding for a mattress that is easy to roll over and has an excellent feel on the floor. Conventionally, cotton has been mainly used as the stuffing for mattresses, but with the increase in the production of synthetic fibers in recent years, thermoplastic synthetic fiber futon cotton is being used as the stuffing for mattresses instead of cotton. However, thermoplastic synthetic fiber futon cotton has better heat retention and bulk retention than cotton, has less sagging, is light and easy to handle, is free from cotton dust, and always stays dry. However, on the other hand, it has poor hygroscopicity and sunlight recovery properties, and is excessively bulky, so it has drawbacks such as the body sinking when sleeping, making it difficult to turn over, and feeling like it is touching the floor. In view of this situation, the inventors of the present invention have conducted various studies, and as a result, they have created a blend of synthetic fibers with different properties.
The present invention was completed by discovering that the above-mentioned drawbacks could be solved all at once by heat-treating the product. That is, the gist of the present invention is to mix thermoplastic synthetic fiber futon cotton A with a single fiber fineness of 5 to 30 deniers and heat-shrinkable fiber B with a single fiber fineness of 1 to 8 deniers, and heat-treat the mixture. It is found in the cotton padding for futons. The thermoplastic synthetic fiber futon cotton A used in the present invention is a polyester fiber with a single fiber fineness of 5 to 30 deniers, preferably 10 to 15 deniers, a fiber length of 3.6 to 6.4 cm, and a crimp rate of 20 ~30% synthetic fibers are preferred. In addition, heat-shrinkable synthetic fiber B used in the present invention
The fiber is selected from polyester fibers and polyamide fibers, has a single fiber fineness of 1 to 8 deniers, preferably 2 to 3 deniers, a fiber length of 3.6 to 6.4 cm, and a heat shrinkage rate of 20 to 40% when dry heated at 100°C. Synthetic fibers are preferred. The denier of the thermoplastic synthetic fiber futon cotton A and the heat-shrinkable synthetic fiber B used in the present invention is preferably within the above-mentioned range, and if it deviates from this range, it will not give favorable results as a mattress padding. . That is, if the denier of the thermoplastic synthetic fiber futon cotton A deviates from 5 to 30, the feel of the futon cotton for mattresses will be impaired.
Furthermore, if the denier of the heat-shrinkable synthetic fiber B is smaller than 1, the binding force with the thermoplastic synthetic fiber A will be weakened, causing displacement of the batting, while if the denier is larger than 8, the cotton texture will change. hardens, which is unfavorable in terms of feel. The thermoplastic synthetic fiber futon cotton A and the heat-shrinkable synthetic fiber B are mixed so that the thermoplastic synthetic fiber futon cotton A accounts for 70 to 80% by weight and the heat-shrinkable fiber B accounts for 30 to 20% by weight. If the filling is heat-shrinkable synthetic fiber B
If the proportion of heat-shrinkable synthetic fiber B is less than 20% by weight, it is undesirable because the thickness of the futon is excessive and the effect of preventing slipping between the fibers of the batting is small. If it exceeds % by weight, the thickness of the futon tends to be slightly thinner, which is not preferable. The cotton blending method is done by carding or the like. The thus-formed blend of thermoplastic synthetic fiber futon cotton A and heat-shrinkable synthetic fiber B maintains the bulk, texture, etc. of the entire cotton due to the large denier thermoplastic synthetic fiber futon cotton A. Tsutsu,
By binding with heat-shrinkable synthetic fiber B, which is a fine denier fiber, the initial bulk of the cotton is reduced to some extent, making it suitable for use in mattresses, while at the same time preventing slippage between the fibers and increasing the elastic recovery power in high load areas. improve,
Heat treated to reduce the feeling of sticking to the floor. The heat treatment method is not particularly limited, but heat treatment methods such as moist heat (autoclape), dry heat, and infrared heating are preferred, and among these, heat treatment by moist heat (autoclape) is particularly preferred. The cotton stuffing obtained by the present invention is particularly preferable as cotton stuffing for bedding, but also for cushions, cushions, etc.
It can also be used in cushions, pillows, etc. As explained in detail above, the mattress padding obtained by the present invention reduces excessive bulkiness to an appropriate bulkiness compared to conventional synthetic fiber futon cotton, and improves body comfort during sleep. It has the advantages of preventing sinking, making it easier to turn over, and alleviating the feeling of being stuck on the floor, so it has extremely high practical value. Next, the present invention will be explained in more detail with reference to Examples, but these are only specific examples and do not limit the present invention. In the examples, three methods were used to evaluate the performance of the padding for mattresses: measurement of the amount of compression of the mattress, compression elastic modulus, and practical test. Examples 1 to 8 The cotton stuffing shown in Table 1 was prepared or used and inserted into a side fabric made of satin, a cotton fabric for making mattresses, measuring 200 cm in length and 100 cm in width to make mattresses. The compression amount and compression elastic modulus of this mattress were measured using the following method. The measuring device was a Tensilon type manufactured by Toyo Baldwin Co., Ltd., and a compressive load of 200 g/cm 2 (35.3 Kg) was applied under a pressurized area of 176.6 cm 2 (φ=15 cm), and a compression deloading thickness curve was drawn. Compression amount (cm) = (H 0 - H 1 ) Compression modulus (%) = H 3 - H 2 /H 1 - H 2 ×100 where H 0 : Thickness when compression load is 0 (cm) H 1 : Thickness at 35g/ cm2 (cm) H2 : Thickness at 200g/ cm2 (cm) H3 : Thickness at 35g/ cm2 when unloading (cm) A 6-month practical test was also conducted. The results are shown in Table 1. As shown in this table, compared to conventional futon cotton futon mattresses made of synthetic fibers, the mattresses with cotton padding obtained according to the present invention have a smaller amount of compression and a higher compressive elastic modulus, making them excellent as cotton for mattresses. It can be seen that it has excellent properties similar to cotton. It also performed well in practical tests.
