Rationale for the choice of material for manufacture of adaptive underclothes for disabled children

The article substantiates the choice of materials for designing adaptive underclothes for the most severe group of children with infantile cerebral paralysis – bed patients. As a rule, these are denied children, who, in principle, spend their lives in medical hospitals, require constant care by medical staff. Such children are in sharp need of specialized adaptive underclothes, which could significantly improve the quality of life of such children and facilitate care for them by medical staff. In many respects the quality of similar clothes depends on properly selected materials. Analysis of modern innovative materials that could have been used to create such clothes was conducted. Hygienic, physical and mechanical properties of existing knitted materials were studied according to standard methods for identifying the most suitable for similar clothes

Rationale of the need for adaptive clothes for disabled children

The study conducted among medical personnel identified that children with infantile cerebral paralysisof the V severity level need clothes with improved properties that ensure the patient’s quality of life and the correct conduct of medical and hygienic procedures by medical personnel

Investigation of the dependence of the internal disruptive pressure in a fire hose on geometric densities on the warp and the weft of its woven reinforcing frame

In this article, based on the obtained formula for calculating the strength of a pressure fire hose(PFN) under the action of internal hydraulic pressure, the dependence of the disruptive pressure in alatex pressure fire hose, designed for an operating pressure of 1.6 H, on such parameters as geometric densities on the warp and the weft, is studied. As a result of the studies, the pattern of decreasing the disruptive pressure of a fire hose with an increase in the geometric densities on the warp and the weft of a reinforcing frame of a pressure fire hose was experimentally established. When designing new fire hoses, it is important to take into account the significant dependence of the disruptive pressure on the geometric densities on the warp and the weft of a reinforcing frame. Recommendations are given on choosing the optimal parameters for a woven reinforcing frame of latex pressure fire hoses with a diameter of 77 mm
