IS 11662 : 2024 Preservative Treatments of Textiles - Code of Practice
1 SCOPE
1.1 This standard specifies treatments (that is, agents, their application and levels) of common preservatives used in textile industry for protection against one or more causes, namely, attack by fungi, bacteria and insects, and degradation caused by the action of weathering and sunlight.
1.2 The materials and processes have been divided into two classes. Class A processes have been generally accepted. Class B processes, although of recognized merit in certain restricted fields, are not yet sufficiently accepted for textiles to warrant inclusion in Class A.
Class A includes the following processes:
a) Zinc naphthenate process;
b) Copper naphthenate process;
c) Cuptammonium process;
d) Mineral khaki process;
e) Chrome tinting process;
f) Salicylanilide process;
g) Pentachlorophenyl laurate process;
h) Copper 8 process;
j) Dichlorophen process;
k) Tar oils process;
m) Dieldrin process; and
n) Halogenated diphenyl urea derivative process.
Class B includes the following processes:
a) Tributyltin oxide process;
b) Orthophenyl phenol (OPP) process; and
c) Pentachlorophenol process.
