Medical disposable protective suit waterproof adhesive tape brief introduction _ production
Original title Brief Introduction of Medical bra tape measure Disposable protective suit Waterproof Adhesive Strip (Die-cutting House April 8) medical protective suit as a kind of anti-chemical clothing is mainly used for medical staff to wear The ideal medical protective suit should be multifunctional not only able to protect medical staff from toxic and harmful liquids gases or infectious viruses and microorganisms but also comfortable to wear with barrier properties but also breathable antibacterial and anti-allergenic not harmful to human health In addition the choice of protective suit fabrics should also consider the cost and environmental protection after waste Requirements to achieve “three refusals and one resistance” that is water-repellent blood-repellent alcohol-repellent and antistatic medical protective suit are different from general woven materials using special composite materials which can be compounded with different materials such as polyethylene/polypropylene spunbonded non-woven fabrics with breathable microporous films or other non-woven fabrics or with Medical Quickly Delivery Antivirus Coverall spunlaced non-woven Or the wood pulp is used for compounding the spunlaced nonwoven fabric At present the nonwovens used in several medical protective suit being sold and developed in the domestic market are mainly as follows Polypropylene spunbonded fabric Spunlaced fabric composed of polyester fiber and wood pulp Polypropylene spunbond-meltblown-spunbond composite nonwoven fabric ie SMS or SMMS Polymer-coated fabric Polyethylene breathable film/nonwoven composite cloth TPU moisture permeable film/nonwoven composite fabric Common medical protective suit usually consist of hats jackets and trousers which have strict standards in production including protection (sealing) clothing safety and hygiene
Through the cutting sewing on the elastic adhesive tape to produce medical protective suit involving the process can not be separated from these three flat seam overlock pressure glue The reason why protective suit can achieve such a high sealing is that it can not be separated from the most important step of pressing glue Aft that protective suit is sewn by a lathe work all stitches and pinholes in the protective suit need to be sealed by pressing glue through a heat seal machine so as to prevent dust or liquid from entering from the sewn pinholes and enhance the isolation performance and use safety of the protective suit As shown in the figure below the adhesive pressing is to press the heat-sealing adhesive tape at the pinhole position of the protective suit through the heat-sealing machine to ensure the sealing of the pinhole position The outbreak of the COVID-19 epidemic with the spread of the epidemic the demand for medical supplies around the surge the most scarce is medical protective suit During the Spring Festival the import protective suit and inventory protective suit played an important role and the follow-up protective suit supply was mainly domestic The Ministry of Industry and Information Technology takes the following measures Expand the full text 1 Make greater efforts to increase production and expand capacity; 2 Do a good job of docking supply and demand and fully guarantee the needs of epidemic prevention and control; 3 Strengthen the control of the whole process of allocation to ensure that key medical supplies are controllable and arrive on time In view of the shortage of medical protective suit many garment enterprises have responded to the call of the state to start production of “protective suit” while working overtime to improve production capacity The official website of the Ministry of Industry and Information Technology also released a proposal for collecting information on layering machines for medical protective suit production on Medical Disposable Coverall February 9 saying that the output of medical protective suit has increased but it is still difficult to meet the current demand for epidemic prevention and treatment Among them the lack of layering machines (also known as hot air seam sealing machines stickers heat sealing machines) and matching heat sealing tapes are the bottlenecks restricting the increase of production and capacity The popular disposable medical protective suit materials on the market are mainly as follows The corresponding sealing processes of these materials are also different Polypropylene non-woven fabrics and SMS non-woven fabrics can be sealed by hot pressing that is two layers of fabrics are heated by a hot press and directly bonded together The hot pressing part will cause the fluctuation of hydrostatic pressure due to the insufficient uniformity of hot pressing Polyethylene microporous membrane/non-woven fabric shall be sealed by means of heat sealing The special polyethylene heat-sealing adhesive tape (hereinafter referred to as PE heat-sealing adhesive tape) for polyethylene microporous membrane shall be pressed at the suture position by using a heat-sealing machine to ensure airtightness The sealing method of TPU film/non-woven fabric is the same as that of polyethylene microporous film/non-woven fabric Use a heat sealer to press the TPU heat-sealing adhesive tape at the suture position to ensure the airtightness PE heat sealing rubber strip PE heat sealing adhesive tape shall be used together with polyethylene microporous film/non-woven fabric
