and A is 98.0 or more, and the weight ratio of the polyvinyl alcohol polymer having a saponification degree of A mol % to the polyvinyl alcohol polymer having a saponification degree B mol % is 2:8 to 8:2. This is a cotton filler containing at least 40% by weight of composite fibers. The polyvinyl alcohol composite fiber used in the present invention consists of a polyvinyl alcohol polymer with a saponification degree of A mol% (hereinafter sometimes simply referred to as PVA-A) and a polyvinyl alcohol polymer with a saponification degree of B mol%. It is a composite fiber in which composite fibers (hereinafter sometimes simply referred to as PVA-B) are joined in a side-by-side type or an eccentric core-sheath type, but the side-by-side type is preferable in terms of the ability to develop crimp. In the present invention, the average degree of polymerization of PVA-A is 1.40 (
It is preferably 1 or more, and particularly preferably in the range of 1,500 to 13,000. The saponification degree is required to be 98.0 mol% or more, preferably 99.8 mol% or more. PV
The average degree of polymerization of A to B is preferably 1,300 or more, particularly preferably in the range of 1,400 to 12,500. The degree of saponification needs to be 0.2 mol% to 2.5 mol% lower than that of PVA-A, preferably 98.
The polymer ranges from 0 to 96.0%. Here, PV
The degree of saponification of A-A is set to 98.0 mol% or more in order to maintain the flexibility and stretchability of the fibers and to reduce the loss in dissolution. Also, PVA-A and PVA-
If the difference in saponification degree from B is less than 0.2 mol%, there is no difference in the water swelling properties of the two types of joined PVA, and sufficient crimp does not occur. If the difference in saponification degree exceeds 2.5 mol%, crimped fibers with good morphology can be obtained, but PV with a low saponification degree can be obtained.
A is more soluble in water, and during repeated use, the fibers stick together and become fecalized, and no crimp occurs, resulting in a water-resistant crimped fiber. More preferably, the difference in degree of saponification is 0.5 mol% to 1
This is the case when it is within mol%. Two types of PVA-A and PVA-B having different degrees of saponification are dissolved in a solvent to prepare two types of polyvinyl alcohol spinning stock solutions. In addition, it is preferable to provide a difference of 50 to 300 in the average degree of polymerization between PVA-A and PVA-B in addition to the saponification degree, which is preferable for self-crimping development and crimp form stability. Furthermore, a coloring agent selected from inorganic pigments, organic pigments, or dyes having a desired color tone is added to PVA-A and/or B in an amount of 0.5 to 5% by weight based on the polymer to prepare a colored spinning stock solution. It is also preferable to do so. The prepared polyvinyl alcohol spinning stock solution is then spun using a wet spinning method or dry spinning method using a bonded composite spinneret to obtain a polyvinyl alcohol composite fiber, and this polyvinyl alcohol composite fiber is stretched and coated with an oil agent. A composite fiber having a single fiber fineness of 0.8 to 10 deniers is obtained by performing the following treatments. The bonding ratio (weight ratio) of PVA is PVA-A
: PVAB=2 : 8 to 8:2, but PVA
- When the ratio of A is less than 20%, the bonded fibers are affected only by the shrinkage behavior of PVA-H and do not develop crimp; on the other hand, when the ratio of A is 80% or more, the shrinkage behavior of PVA-B Since the stress is small, it cannot contract and crimp does not occur. Preferably, by setting the bonding ratio of PVA to 4:6 to 6:4, stable crimp can be developed without causing peeling of the bonded portion, and the final result is a material with good shape stability. , a cotton pad with high bulk due to the appearance of crimp is obtained. The crimped fibers may have any cross-sectional shape, such as circular, flat, triangular, T-shaped, or Y-shaped. The composite fiber thus obtained exhibits a high degree of three-dimensional crimp through subsequent heat treatment, thereby maintaining the bulkiness of the product. Heat treatment can be carried out, for example, at 80 to 90°C in hot water, at 110 to 120°C in wet heat, or at 15°C in dry heat.
Although it is possible to carry out the process at a temperature of about 0°C, it is most preferable to carry out the process in hot water. In the present invention, this polyvinyl alcohol composite fiber is cut into pieces of, for example, about 20 to 100 mm to be used as raw cotton for the padding, but up to 60% by weight of the padding may be There is no problem in blending other chemical fibers, natural fibers, etc. In addition, thermal binder fibers may be blended to form a hard cotton, such as core-sheath type thermal binder fibers in which a polymer having thermal adhesive properties such as copolyester or polyolefin is arranged as a sheath component. It is possible to use In this case, the thermal binder fiber is 40% to 10% by weight.
It is desirable to have a cotton blending rate of about 100%. In the present invention, the above-mentioned polyvinyl alcohol-based composite fibers and fibers are blended with other raw cotton as necessary, and this is carded to form a carded web.Then, the webs are laminated and placed inside a side fabric or shortened. By blowing the fibers into the side fabric using an air stream and then applying heat treatment,
It can be used as a filling for futons, comforters, cushions, etc. In addition, for example, a mixture of polyvinyl alcohol composite fibers and a thermal binder is made into a random web, a cross-wrap web, a parallel web, etc., and after being entangled by a needle punch method, a hydroentanglement method, etc. as necessary, By applying heat treatment to develop crimp and thermal bonding, it can be used as a bulky nonwoven fabric for quilting mats for infants and cotton padding for clothing. 7. The cotton wafer made of the self-crimping polyvinyl alcohol composite fiber of the present invention has excellent bulkiness due to stable and good self-crimping and morphological stability in a water absorption state, and has the properties of the polyvinyl alcohol composite fiber. Due to the synergistic effect of these properties, it has high water absorption, hygroscopicity, high air permeability, moisture permeability, and heat retention, and is lightweight and flexible. The filling cotton of the present invention can be used, for example, in mattresses, comforters, cushions, pillows, cushions, quilted fabrics, winter sports clothing or outdoor work clothes, gloves, sofa-1 rugs, etc. Ideal for filling cotton, etc.

It was measured based on the 6,1A method. 81 Example 1 Polyvinyl alcohol AI with a saponification degree of 99.98 mol% and polyvinyl alcohol with a saponification degree of 97.5 mol%
% and mixed polyvinyl alcohol B1, which is a mixture of 75% polyvinyl alcohol group, were respectively dissolved in a solvent to prepare a spinning solution. Each spinning solution was subjected to side-by-side composite spinning with a polyvinyl alcohol bonding ratio of 1:1 in a dry method using a bonded spinneret, drawn 4.0 times, mechanically crimped, and cut into fibers with a length of 51 mm. A staple fiber of polyvinyl alcohol composite fiber having a fineness of 2.5 dr was obtained. On the other hand, the thermal binder fiber is a core-sheath type composite fiber whose core component is 40 parts of polyethylene terephthalate and whose sheath component is 60 parts of a polyester copolymer, using staple fiber with a fineness of 3 dr and a fiber length of 51 mm, and a polyvinyl alcohol composite fiber of 80 parts. and 20 parts of thermal binder fiber were blended and passed through card and random univer to give an average basis weight of 45 g/
A random web of m' was made, two sheets were laminated, and temporary needle punching using a presser was performed at 30 punches/cffl''. Next, the polyvinyl alcohol fibers were treated in hot water at 90°C to develop self-crimping. The fibers were made into micro-crimped fibers, squeezed, dried in a hot air dryer at 135°C, and bonded between the fibers using a thermal binder fiber.The obtained nonwoven fabric had an apparent density of 0.12 g/cm' and an average basis weight. It was a stable bulky non-woven fabric with a form of 114 g/m2, and the water absorption rate of this non-woven fabric was 91% and the water absorption rate was 0.8 seconds. This non-woven fabric was used as a filling material for quilting to make quilt fabric. For comparison. For this purpose, quilted fabric was made using polyester cotton made by mechanically crimping hydrophilic polyester fibers and used as padding in the same manner as in Example 1.Vests were made from these quilted fabrics. When worn, the item in Example 1 was warm without making the skin feel stuffy even when worn for a long time, and no change in shape or bulk was observed even after washing with water 10 times. As for the comparative example, when the number of washes increased, the feeling of stuffiness became stronger, a decrease in moisture absorption and aqueous properties was observed, and swelling was observed due to changes in the cotton padding.Example 2 Average degree of polymerization 1800, degree of saponification 99 .97 mol% polyvinyl alcohol 8, average polymerization degree 750, saponification degree 9
A spinning solution was prepared by dissolving 25% of 7.2 mol% polyvinyl alcohol and mixed polyvinyl alcohol B, which is a mixture of 75% polyvinyl alcohol A and polyvinyl alcohol A, in respective solvents. Each spinning solution was subjected to side-by-side composite spinning using a joint type spinneret using a dry method with a polyvinyl alcohol joint ratio of III, drawn to 4 times, and mechanically crimped to a fiber length of 6.
A staple fiber of polyvinyl alcohol fiber having a diameter of 0 mm and a fineness of 6.5 dr was obtained. The fibers were passed through a card and a random univer to obtain a fiber web with an average basis weight of 1200 g/m'. This fibrous web was sprayed with 120 g/m2 of water and passed through a hot air heating oven at 135° C. to be dried and heat-treated to cause the polyvinyl alcohol composite fibers to develop self-crimping. The obtained nonwoven fabric was a bulky nonwoven fabric with an apparent density of 0.09 g/am3 and an average basis weight of 147 (Ig/m2). It was suitable as cotton. Example 3 Polyvinyl alcohol A3 with an average degree of polymerization of 1800 and a degree of saponification of 99.98 mol% and an average degree of polymerization of 1600 and a saponification degree of 9
Mixed polyvinyl alcohol B3, which is a mixture of 20% of 8.0 mol% polyvinyl alcohol and 80% of polyvinyl alcohol A3, is dissolved in a solvent, respectively, and a fruit and vegetable coloring agent is added to the spinning stock solution at 1.5% based on the polyvinyl alcohol.
A spinning solution was prepared by adding the following crucible. Each spinning solution was subjected to side-by-side composite spinning using a bonded spinneret using a dry method with a polyvinyl alcohol bonding ratio of 1:■, drawn to 3.7 times, and mechanically crimped to a fiber length of 5.
It was cut into 1 mm to obtain staple fibers with a single fiber fineness of 2 dr. 70 parts of this staple fiber and thermal binder composite fiber (core-sheath type composite fiber whose core component is polyethylene terephthalate-1 and whose sheath component is polyester copolymer, fineness 2.5 d)
r, fiber length 51 mm) and 30 parts of the fibers were mixed together using a dry method to make a fiber web with an average width of 450 g/m2.
Make 21 dollar punches on both sides with a #40 needle, totaling 28
0 punch/cm' was performed to entangle the fibers to obtain a fiber entangled nonwoven fabric. Next, this fibrous nonwoven fabric was sprayed with 50 g/m' of water and dried for 15 minutes in a hot air atmosphere at 135°C.
Heat treatment was performed to adhesively fix the joints of the fibers with binder fibers, and the polyvinyl alcohol composite fibers were made to develop self-crimping. The obtained nonwoven fabric was a bulky nonwoven fabric with polyvinyl alcohol composite fibers exhibiting beautiful micro-crimps and an apparent density of 0.16 g/cm 3 . When this nonwoven fabric was used as padding for cushions, a product with stable shape was obtained.
