INVESTIGATION OF THE PROPERTIES OF STYRENE-ACRYLIC POLYMER MATRIX TO CREATE A COATING ON COTTON KNITTED FABRIC

Abstract

The  goal  of  the  work  was  to  study  the  physico-chemical  properties  of  styrene-acrylic polymer film to form a coating on a textile material. Methodology.  A  water  dispersion  of  a  styrene-acrylic  copolymer  was  used  as  an  object  of  study.
Standardized  methods  for  studying  the  indicators  of  the  physicochemical  properties  of  polymer  films  and physical  properties  of  textile  materials  have  been  applied.  The  study  of  the  structural  parameters  of  an individual  polymer  film  was  carried  out  using  the  sol-gel  method.  The  physical  properties  of  the  studied polymer  material  were  evaluated  according  to  the  results  of  the  resistance  of  the  film  to  hydrolytic degradation  at  different  processing temperatures  and  the  effects  of  soap  and soda  solution.  The  quality of
cotton  knitted  fabric  with  the  formed  polymer  coating  was  evaluated  by  the  change  in  hygroscopicity  and breathability. The  paper  presents  the  results  of  a  study  of  the  structural  and  physical  properties  of polymer film  based  on the  styrene-acrylic  copolymer.  The optimal  polymer  composition  was determined  to create a coating on the textile material and the concentration of the proposed composition was established, at which the hygienic properties of the cotton knitted fabric did not deteriorate. Originality.  It  is  proved  that  the  proposed  polymer  composition  allows  you  to  create  a  resistant coating on cotton knitted fabric and at the same time keeps hygroscopicity and breathability of knitted сloth. Practical value. The results of the experiment are of practical importance for the development of new finishing compositions for textile materials.
