Abstract
Disclosed is a method for providing a textile material(s) resistant to the deposition of oil- and grease-based air pollutants by treating the textile material(s) with an oil/grease resistant composition. The oil/grease resistant composition comprises a modified polysaccharide(s), particularly, polysaccharides modified with anionic groups, and one or more adjuvant materials.
Claims7
A method for providing a textile material which is resistant to the deposition of oil-and grease-based air pollutants, the method comprising the steps of:
- i. treating the textile material with an oil and grease resistant composition comprising blocky carboxymethyl cellulose (CMC) and optionally at least one adjunct material;
- and
- ii. drying the resultant textile material of step (i) wherein the blocky carboxymethyl cellulose has a degree of substitution (DS) of at least 0.4, and a degree of blockiness (DB) of at least 0.5,
- wherein the blocky carboxymethyl cellulose has a molecular weight in the range of from 100,000 Daltons to 1.5 million Daltons.
