Introduction

GB/T 18916.14—2023 Interpretation of Water Quota for Wool Textile Products

Background of Standard Formulation and Analysis of Technology Evolution

As the problem of water shortage in my country becomes increasingly prominent, the country pays more and more attention to the construction of a water-saving society. As an important basis for regulating industrial water management, the GB/T 18916 series of standards are of great significance for promoting enterprises to improve the efficiency of water resource utilization.

As a typical high-water-consuming industry, the formulation and revision of water quotas for the wool textile industry are directly related to the sustainable development of the industry.

The scope of application of the standard has been adjusted.
The calculation scope of water withdrawal has been increased.
The water withdrawal quota indicators have been updated.

Product Name		Process Boundary	Unit	Unit Product Water Intake (cubic meters)
Scourred Wool Tops		Raw Wool - Scoured Wool Tops	m³/t	12	16
Carbonized wool		Raw wool-carbonized wool	m³/t	16	22

Explanation of professional terms and application cases for standard implementation

Water quota refers to the maximum amount of water allowed for the production of a unit product under specific conditions. Enterprises should strictly manage water resources in accordance with the advanced values and general values specified in this standard in actual production.

For example, a wool textile enterprise reduced the water intake per unit product from 16 cubic meters/ton to 12 cubic meters/ton by optimizing the dyeing process and adopting a recycling water system, significantly improving the water-saving effect.

Comparison of standard framework

Compared with GB/T 18916.14-2014, the main changes are as follows:

Old version content	New revised content
Scope of application is limited to wool textile enterprises	Extended to all units involved in the production of wool textile products
The calculation of water intake for auxiliary production systems is not clear	The water intake range for auxiliary and ancillary systems has been added

Implementation Suggestions

To ensure the effective implementation of the standard, enterprises are advised to take the following measures:

Strengthen the deployment and management of water metering instruments
Carry out water balance tests regularly
Optimize production process
Promote recycling water technology
Establish water-saving incentive mechanism
