AI Technical Summary
The use of polylactic acid film in isolation suits is compromised by its low high-temperature resistance during ultrasonic splicing, leading to damage and reduced waterproofness, which can compromise the suit's ability to prevent liquid contaminants.
The isolation suit employs a sealing assembly with a seam layer and a rubber strip layer to cover the seams, using adhesive strips to enhance sealing and waterproof properties, replacing ultrasonic heat sealing to protect the polylactic acid film.
This approach improves the overall sealing and waterproofness of the isolation suit, preventing liquid contamination and enhancing user safety by maintaining the integrity of the polylactic acid film.

[0036] At present, in the market, for places such as ICU and surgical examination, medical protective products made of degradable textile materials are generally used, such as isolation suits, which are mainly used to protect staff and patients, avoid contact with pollutants and infection, and avoid cross infection between staff and patients. After use, under composting conditions, it can be completely biodegraded within a few months, not only without burdening the environment, but also participating in natural circulation, meeting the current green environmental protection and sustainable development concepts. At the same time, in order to improve the waterproofness of the isolation suit, a layer of polylactic acid film will be covered on the outer surface of the degradable textile. However, in the production process of the isolation suit, ultrasonic suture technology is generally used to splice multiple splicing parts of the isolation suit (such as the suture parts of the garment itself, the suture parts of the sleeve itself, and the suture parts of the garment and the sleeve) , and the high temperature resistance of the polylactic acid film is lower than the ultrasonic heat-sealing temperature, resulting in the polylactic acid film being damaged by high temperature during the splicing process, affecting the sealing of the isolation suit, thereby reducing the waterproofness of the isolation suit, making it easy for liquid pollutants to infect the isolation suit when contacting the isolation suit, thereby affecting the safety of the isolation suit.

[0039] In the technical solution of the present invention, the main body 1 of the isolation suit 100 is spliced by the sealing assembly 2. Specifically, the seam layer 2a is provided at a plurality of splicing positions of the main body 1 to sew and splice the main body 1 by means of seams, and the outer surface of the seam layer 2a is covered with the adhesive strip layer 2b to seal the seam layer 2a, thereby improving the sealing and waterproof properties of the splicing positions of the main body 1. Compared with the splicing method using ultrasonic heat sealing, the polylactic acid film layer 1b can be prevented from being damaged by high temperature, thereby improving the overall sealing and waterproof properties of the isolation suit 100, and preventing liquid contaminants from invading the isolation suit 100 and infecting the user, thereby improving the safety of the isolation suit 100.
[0040] It should be noted that, in the present invention, the adhesive strip layer 2b can be evenly and neatly covered on the seam layer 2a by a stripping machine without pilling, bubbles, wrinkles, etc., so that the sealing performance is good.
[0041] For further information, see Figures 1 to 3The main body 1 includes a first splicing position, a second splicing position and a third splicing position, and the sealing assembly 2 includes a first sealing member 21, a second sealing member 22 and a third sealing member 23; the main body 1 includes a body 11 formed by a garment piece 111, and two sleeves 12 formed by a sleeve piece 121, the garment piece 111 has a neckline 1111, two armholes 1112, and two shoulder line 1113 groups, the two armholes 1112 are respectively arranged on the left and right sides of the neckline 1111, and the two shoulder line 1113 groups are arranged on the left and right sides of the neckline 1111, each of the shoulder line 1113 groups includes two shoulder lines 1113, the two shoulder lines 1113 of one of the two shoulder line 1113 groups are arranged on the left and right sides of one of the two armholes 1112, and the other shoulder line 1113 of the two shoulder line 1113 groups The two shoulder lines 1113 of one are arranged on the left and right sides of the other of the two armholes 1112; the first splicing position is formed between the two side lines of each sleeve piece 121 on its width, and the seam layer 2a of the first sealing member 21 is arranged at the first splicing position to sew the sleeve piece 121 into the sleeve 12; the second splicing position is formed between the connecting end of each sleeve 12 and the periphery of the corresponding armhole 1112, and the seam layer 2a of the second sealing member 22 is arranged at the second splicing position to sew the body 11 and the sleeve 12; the third splicing position is arranged between the two shoulder lines 1113 of each group of shoulder lines 1113, and the seam layer 2a of the third sealing member 23 is arranged at the third splicing position to sew the two shoulder lines 1113 to form the shoulder of the body 11.

[0042] For further information, see Figure 4 The length of the rubber strip layer 2b is greater than the length of the seam layer 2a, and the width of the rubber strip layer 2b is greater than the width of the seam layer 2a; in this way, the rubber strip layer 2b can completely cover the seam layer 2a, thereby improving the sealing and waterproof properties of the splicing and seaming points of the isolation suit 100.
[0043] Furthermore, while preventing the adhesive strip layer 2b from being too narrow, it should also be avoided that the adhesive strip layer 2b is too wide, which may cause the stripping machine to have a poor hot-melt effect on the edge of the adhesive strip layer 2b. Therefore, in one embodiment of the utility model, the width of the seam layer 2a is W1, and 0.4cm≤W1≤1.0cm; the width of the adhesive strip layer 2b is W2, and 1.8cm≤W2≤2.0cm, so that the periphery of the adhesive strip layer 2b can be firmly attached to the garment piece 111 to compress and seal the seam layer 2a.

[0045] More specifically, in an embodiment of the present invention, the diameter of the through hole 122 is set to 2.5 cm.
[0046] Furthermore, the cuff end of the sleeve 12 is provided with an adjusting piece, and the adjusting piece is used to adjust the opening area of the cuff end; thereby, the cuff end of the sleeve 12 can be adjusted according to users of different physiques, and the cuff end can be widened when putting on and taking off the isolation suit 100, which is convenient for users to put on and take off; the cuff end can be tightened during work to prevent pollutants from entering the isolation suit 100 through the cuff end and infecting the user.
[0047] Furthermore, the adjusting member may be a tightening rope or the like.
[0048] For details, please refer to Figure 1 and Figure 2 The isolation suit 100 also includes a polylactic acid tie 3, which is sewn to the collar 1111. In this way, the polylactic acid tie 3 is placed around the neck of the user and tied behind the user, so that the body 11 can be fixed at the neck of the user. The polylactic acid tie 3 is degradable, which meets the current green environmental protection and sustainable development concepts.
[0049] For details, please refer to Figure 1 and Figure 2 The isolation suit 100 also includes a polylactic acid belt 4, which is arranged at the middle part of the garment piece 111 in its length direction, so that the garment piece 111 is enclosed by the polylactic acid belt 4 to form the garment body 11 to cover the body of the user, and the polylactic acid belt 4 is tied behind the user to fix the garment body 11 on the user; and the polylactic acid belt 4 is degradable, meeting the current green environmental protection and sustainable development concepts.
