3 Terms and definitions
For the purposes of this document, the terms and definitions given in GB/T 3291.1, GB/T 3291.3, GB/T 4146(whole) and the following apply.
3.1
alginate
salt produced by the reaction of alginic acid with Na
3.2
alginate staple fibre
staple fibre with alginate content more than 85%, which is produced by spinning with sodium alginate as raw material
4 Categories and identification
4.1 Product categories
According to application, there are two categories—alginate staple fibre for spun or for non-woven.
4.2 Product specification
The specification of staple fibre is expressed in terms of its linear density and length.
EXAMPLE 1,67 dtex × 38 mm or 2,78 dtex × 51 mm
4.3 Product identification
Alginate staple fibre is clearly identified by information, such as its specification, product categories, product name and batch number.
5 Technical requirements
