Then, the lower garment was taken out from the packaging bag and worn.
  • Example 4 When sewing the upper and lower garments of the protective suit, the protective suit was sewn, packaged and evaluated in the same manner as in Example 1 except that the ends of the cloth were sewn together with a lock stitch sewing machine so as to cover the ends of the fabric.
  • Example 5 Using 2 sheets of spunbonded non-woven fabric, a hot-melt adhesive machine was used to heat and melt the hot melt adhesive at 150 ° C to the first side of 1 sheet of spunbonded non-woven fabric at an application amount of 1.5 g / It was applied in a spray form from a T-die so as to be m 2 . Then, the melt blown nonwoven fabric was bonded to the first surface of the spunbonded nonwoven fabric coated with the hot melt adhesive. Further, the hot-melt adhesive heated to 150 ° C. and melted was sprayed from the T-die onto the melt-blown non-woven fabric side of the obtained spunbonded non-woven fabric / melt-blown non-woven fabric so that the coating amount was 1.5 g / m 2. Applied.
  • Example 6 Using 2 sheets of spunbonded non-woven fabric, a hot melt adhesive machine was used to heat and melt the hot-melt adhesive at 150 ° C to the first surface of 1 sheet of spunbonded non-woven fabric at a coating amount of 2.5 g / It was applied in a spray form from a T-die so as to be m 2 . Then, the melt blown nonwoven fabric was bonded to the first surface of the spunbonded nonwoven fabric coated with the hot melt adhesive. Further, the hot-melt adhesive which was heated to 150 ° C. and melted was sprayed from the T-die onto the melt-blown non-woven fabric side of the obtained spunbonded non-woven fabric / melt-blown non-woven fabric so that the coating amount was 2.5 g / m 2.
  • the hot melt adhesive which was heated to 150 ° C. and melted was applied to the film side of the SF nonwoven fabric of Example 1 in a spray form from a T die so that the application amount was 2 g / m 2 . After that, another spunbonded nonwoven fabric was attached to the film surface coated with the hot melt adhesive to obtain an SFS nonwoven fabric.
  • a hooded upper garment and a lower garment were sewn with an overlock sewing machine to obtain a protective suit.
  • the hood had a bilaterally symmetrical shape as shown in FIG. 6 and was obtained by joining two left and right sheets.
  • a flat rubber having a width of 1 cm and a length of 60 cm was inserted into the waist of the lower garment.
  • This protective garment was folded without folding the hem of the upper garment and the waist of the lower garment was not folded, placed in respective packaging bags, subjected to electret processing, and further subjected to sterilization processing with ethylene oxide gas.
  • Example 2 Using the SMS nonwoven fabric obtained in Example 1, a protective garment was sewn in the same manner as in Example 1 except that the following points were changed.
  • the hood had a shape in which the parietal region and the temporal region were sewn in the same manner as in Example 1, and an opening with a width of 15 cm and a length of 11 cm was provided in the center, but all were sewn with SMS non-woven fabric, and a locking device. Finished without attaching. Further, sewing was performed by ultrasonic welding.
  • This protective garment was folded without folding the hem of the upper garment and the waist of the lower garment was not folded, placed in respective packaging bags, subjected to electret processing, and further subjected to sterilization processing with ethylene oxide gas.
  • Example 3 The SF non-woven fabric obtained in Example 1 was used to sew upper and lower joint-type protective clothing.
  • the tie type is a shape in which the hood, front body, back body, sleeves, and pants are integrated, and the front body can be opened and closed by sewing fasteners.
  • the hood had a bilaterally symmetrical shape as shown in FIG. 6, two pieces were joined to each other on the left and right sides, and a string-like locking tool having a width of 2 cm and a length of 60 cm was sewn to the left and right of the opening with the same SF nonwoven fabric as the body.
  • This protective suit was folded, put in a packaging bag, subjected to electret processing, and further subjected to sterilization processing with ethylene oxide gas.
  • the protective clothing top and bottom was taken out from each packaging bag and the wearing time was measured. Although the time required for clothing was increased by the number of steps increased by 2 steps, such as opening the fastener on the front body of the body and then wearing the fastener, and then closing the fastener, the pseudo-pollutant was hardly attached.
  • the evaluation results are shown in Table 4.
  • the same wearing test as the above protective clothing was conducted.
  • the evaluation results are shown in Table 4.
  • the number of wearing procedures was the same as in Reference Example 1, but adhesion of pseudo contaminants was observed on the upper garment hem, lower garment waist, lower garment hem, and lower garment buttocks. It was difficult to wear without touching the outer side when wearing it, such as when the upper and lower garments contacted the outer side of the protective clothing when opened, and there were many contact points on the outer side. Also, wearing clothes was long.
  • Adhesion was observed at the top of the hood, near the center in front of the tie, and around the collar of the tie. It is probable that he had to touch these parts because he put on the hood to adjust the wearing condition and put the hood in the joint. In addition, it takes time to find a place that does not adhere to the outside when the bag is opened, and the legs contact the floor surface even when it is worn, and the hood is put in the protective clothing, so the wearing time becomes long. As a result, there were many contact points to the outside.
  • the protective clothing of the present invention has excellent wearing comfort and suppresses the generation of dew condensation, so that it is preferably worn in a sealed space such as a clean room.
