It is a table | surface which shows the content of the resin composition of each Example, the moisture content of a molded article, a physical property value, etc. It is a table | surface which shows the content of the resin composition of each comparative example, the moisture content of a molded article, a physical property value, etc.

  The clothing reinforcing member 10 shown in FIG. 1 is an embodiment of the clothing reinforcing member of the present invention, and is used as an underwire of a brassiere. Further, the shape of the clothing reinforcing member of the present invention is not limited to a wire, but may be a shape corresponding to the clothing to be used and the location of use, and may be a plate shape or the like.

  The reinforcing member for clothing 10 is formed from a resin composition containing a polyamide resin as a main component and having a saturated water absorption (in water, ISO 62) of 4.0% or more, and a molded article having a water content of 20% of the saturated water absorption. ９０90% (that is, the water content is 20-90%). The moisture content of the molded product is 2 to 10%.

The saturated water absorption (in water, ISO 62) of the resin composition is a value measured by injection molding a flat plate of 100 mm × 100 mm × t2 mm from the resin composition and measuring the conditions specified in the ISO 62A method.
The moisture content of the molded article is obtained by injection molding the resin composition, calculating the molded article by a loss on drying method, and is determined by the following equation. The drying condition is 110 ° C. × 24 hours.
“Moisture percentage of molded article = (weight of sample before drying−weight of sample after drying) / weight of sample before drying × 100”
The water ratio is a value obtained by the equation [water ratio = water ratio of molded article / saturated water absorption × 100]. If the moisture ratio is less than 20% (the moisture content of the molded product is less than 20% of the saturated water absorption), the bending resistance is poor, and the moisture ratio exceeds 90% (the moisture content of the molded product is 90% of the saturated water absorption). %), The rigidity is inferior.

  As the polyamide resin, those having 4 to 11 carbon atoms between amide bonds are preferable. For example, polyamide 6 (5 carbon atoms between amide bonds, saturated water absorption (ISO62) 10%), polyamide 66 (4 and 6 carbon atoms between amide bonds, 9% saturated water absorption (ISO62)), polyamide 610 (amide C6 and C8 between bonds, saturated water absorption (ISO62) 8%), and polyamide 46 (C4 and C4 between amide bonds, saturated water absorption (ISO62) 12%). The polyamide resin is not limited to one kind, and a mixture of two or more kinds can be used.

In the resin composition, a thermoplastic elastomer or an inorganic filler can be used as another compounding material.
Examples of the thermoplastic elastomer include styrene-based elastomers such as styrene-butadiene block copolymer and styrene-isoprene copolymer. Examples of the olefin-based elastomer include polyethylene, polybutene, polypentene, ethylene-vinyl acetate copolymer, ethylene-vinyl alcohol copolymer, ethylene-propylene rubber (EPR), and ethylene-propylene-diene rubber (EPDM). An elastomer obtained by grafting a polar group such as maleic anhydride, styrene, acrylonitrile, or the like to an olefin-based elastomer is more suitable.
The thermoplastic elastomer is not limited to one type, and a plurality of types may be blended. Flexibility and impact resistance can be increased by blending the thermoplastic elastomer. When the thermoplastic elastomer is compounded, the compounding amount is preferably 5 to 100 parts by weight based on 100 parts by weight of the polyamide resin. When the amount is less than 5 parts by weight, the effect of increasing the bending resistance and the impact strength is small, and when the amount is more than 100 parts by weight, the rigidity is reduced.

  As inorganic fillers, mica, talc, kaolin, silica, calcium carbonate, layered silicate, barium sulfate, glass beads, glass flakes, clay, molybdenum disulfide, wollastonite, calcium polyphosphate, alumina, zinc oxide, titanium oxide , Magnesium oxide, boron nitride, aluminum nitride, carbon, carbon nanotube, glass fiber, carbon fiber, cellulose fiber, alumina fiber and the like. The inorganic filler may be treated with a coupling agent or another surface treatment agent.

  As for the size of the inorganic filler, any size of macro size (particle diameter of about 100 μm to 10 μm), micro size (particle diameter of about 10 μm to 100 nm), and nano size (particle diameter of about 100 nm to 10 nm) can be used, In order to improve the bending resistance of the resin composition, it is preferable that the inorganic filler is nano-sized and dispersed in the resin. Examples of the shape of the inorganic filler include a granular shape, a needle shape, a fiber shape, and a plate shape, and any of them can be used, but a plate shape having a high rigidity increasing effect is preferable. Preferred plate-like inorganic fillers that can be dispersed in nano size include mica, layered silicate, wollastonite and the like. The rigidity can be increased by blending the inorganic filler. When the inorganic filler is compounded, the amount is preferably 0.1 to 10 parts by weight based on 100 parts by weight of the polyamide resin. When the amount is less than 0.1 part by weight, the rigidity increasing effect is small, and when it is more than 10 parts by weight, the bending resistance is poor.

  The reinforcing member for clothing of the present invention has a bending resistance of 100 times or more, and when used as an underwire of a bra, does not break even when a large load is applied during washing or the like. The bending resistance was determined by using a strip-shaped test piece having a width of 5 mm, a thickness of 1.5 mm and a length of 150 mm, and fixing one end A and the center with a clamp, and the other end B which was not fixed. Was bent until it touched the fixed end A, and then returned to the original state. This bending and returning were repeated, and the number of times of bending until breaking was measured as the number of times of bending resistance.

The manufacturing of the garment reinforcing member 10 is performed by forming the garment reinforcing member into a shape of a garment reinforcing member by a known resin molding method, then performing a water absorption step, and then performing drying.
The resin molding method is not limited to injection molding, and a known molding method used for resin molding such as extrusion molding or press molding is used.
The water absorption step is performed by immersing the molded article obtained by molding in water at 30 to 95 ° C. or warm water for 5 to 100 hours, or by leaving it at 23 ° C. and 70% humidity for 30 days.
Drying after the water absorption step is performed by leaving the apparatus at a predetermined temperature (80 ° C. or lower), blowing air, or wiping it with a cloth. The drying time is not particularly limited as long as there is no moisture attached to the surface of the clothing reinforcing member.
By performing the water absorption step, the moisture ratio of the clothing reinforcing member is 2 to 10%, and the moisture percentage of the molded article with respect to the saturated water absorption can be 20% to 90%. Thereby, even if a large load is applied at the time of washing or the like, it does not break, and it is suitable as a reinforcing member for clothing.
