SHEET MATERIAL Russian patent published in 2021 - IPC D06N3/12 D06M15/564 B32B5/26 B32B5/28 

FIELD: chemistry; textile industry.

SUBSTANCE: invention relates to the field of chemical technology of textile materials and concerns sheet textile material in which plant raw materials with low environmental impact are used. Sheet material is characterized by the fact that it is made of non–woven material, which is made of polyester microfiber containing a component obtained from 1,2-propanediol in the specified amount and polyurethane elastomeric resin containing structural monomers. Sheet material is also made of a main sheet, in which non-woven material that has microfibers as a main component is laminated and combined with woven or knitted material and elastomeric resin, and this material is made of fibers containing polyester as a main component, this polyester contains 1-500 parts per million of the component obtained from 1,2–propanediol. The invention also proposes sheet material that, in the best performance, has uniform and fine pile and that is durable, has excellent shape stability, that is light and very soft.

EFFECT: invention provides for the creation of pile sheet material having uniform and elegant piloerection, even in the case of using fiber containing components obtained from plants and elastomeric resin, as well as sheet material having high strength, excellent shape stability, light weight and high flexibility, using woven or knitted material including fiber containing components obtained from plants.
