Abstract

Antimicrobial textile material for the manufacture of a garment that removes and localizes the products of human skin respiration, consisting of 2 fibrous layers, one of which, intended for contact with the human body, is made of hydrophobic fibers, and the second is made of hydrophilic fibers fastened together by stitching threads with knitted weave, characterized in that a textured untwisted polyester antimicrobial thread is used as a sewing thread in an amount of 25-30 wt% of the surface density of the textile material.

Description

The invention relates to non-woven textile materials based on chemical fibers (viscose, polypropylene) and yarns (polyester), intended for the manufacture of garments for the removal and localization of human skin respiration products, mainly in the form of linen, worn directly on the human body.

A sewing product for the removal and localization of human skin respiration products is known, made of a textile material consisting of layers bonded together by piercing threads, one of which has a hydrophobic surface designed to come in contact with human skin, and the second is made in the form of a fibrous layer containing hydrophilic fibers. The product of this material well absorbs skin respiration products that freely penetrate the fibrous layer of hydrophobic fibers (MKI D04N 1/52 of the Russian Federation No. 2130746, publ. 05.27.99).

In essence and the technical result achieved, said textile material for the manufacture of garments is closest to the proposed invention and is taken as a prototype.

The aim of this invention is the creation of such a non-woven textile material, which along with high absorbency, the ability to localize and retain moisture (sweat) in its structure had antimicrobial properties.

To achieve this goal in a textile material for the manufacture of a garment that diverts and localizes human skin respiration products, consisting of 2 fibrous layers, one of which is intended for contact with the human body, is made of hydrophobic fibers, and the second is made of hydrophilic fibers , the layers are bonded to each other by stitching with knitted weaving, and a textured untwisted polyester antimicrobial thread in an amount of 25-30 wt.% surface is used as a stitching thread lotnosti textile material.

According to the invention, the bonding of the formed two-layer fibrous canvas was carried out by means of a piercing thread of a polyester textured untwisted antimicrobial knitted weave at certain technological parameters, in particular, the density of the piercing. With this density of the firmware, the content of the antimicrobial filament in the material is achieved in an amount of 25-30 wt.% Of the surface density of the material. The content of the antimicrobial filament in an amount of 25-30 wt.% The surface density of the material allows to obtain the material of the optimal structure with the necessary set of properties, namely: strength, softness and antimicrobiality. With a decrease in the content of the antimicrobial filament (15-20 wt.%), The strength of the material decreases and, as a result, a decrease in the service life. With an increase in the content of antimicrobial filament (up to 40 wt.%), The material becomes dense and hard, which is undesirable for materials of the linen group.

Textured non-twisted polyester thread contains an antibacterial additive based on silver ions and is produced by RUE SPO Khimvolokno (Svetlogorsk) in accordance with TU BY 400031289.013-2008.

The formation and bonding of a fibrous canvas by knitting interweaving of stitching threads was carried out in a single technological process on the well-known knitting-stitching units of the type “AChV” or “Malivatt” (see, for example, Perepelkin MP and others. “Mechanical technology for the production of nonwoven materials” M. "Light Industry", 1973, S. 309-311,302), etc. equipment.

The surface density of the textile material is, for example, 110-250 g / sq.

Evaluation of antimicrobial activity was carried out on a gram-positive strain of Staphylococcus aureus FDA 209-P (ATCC 6538-P) and gram-negative Escherichia coli (ATCC 25922). The results are presented in table 1.

Table 1 Inhibition of growth of Escherichia coli (ATCC 25922) and Staphylococcus aureus FDA 209-P (ATCC 6538-P) non-woven fabric before washing and after washing in relation to the control sample Sample Microbial load Suppression before washing Suppression after washing times % times % Anti-microbial sweat-absorbing non-woven fabric E.coli 10 ³ mk./ml 1000 99.9 500 99.8 10 ⁵ m.k. / ml 100,000 one hundred 5000 99.98 10 ⁷ m.k. / ml 22.5 95.6 4.7 78.9 S. aureus 10 ⁷ m.k./ml 2 46 1,6 60

As can be seen from the data in table 1, non-woven material containing a thread with an antibacterial additive significantly inhibits the growth of E. coli in the entire range of microbial loads. The sample after washing maximally preserved antimicrobial properties.

The material has antimicrobial activity against Staphylococcus aureus FDA 209-P (ATCC 6538-P) with a microbial load of 10 ⁷ m.k. / ml before washing and after washing.
