導入
This document defines defining terms for the physical properties of tissue paper manufactured using wrinkling or non-wrinkling techniques and includes products made using a combination of these tissue paper manufacturing processes.

Paper towel products are an important and growing market for single-use disposable sanitary and industrial products. The current range of familiar products includes toilet paper, facial tissues, kitchen/household towels, hand towels, napkins, MATS, industrial wipes, other absorbent tissues and lotion treatments.

Tissue paper manufacturing techniques have evolved and deviated from “normal” paper techniques, so there is a need for a new vocabulary.

The purpose of this document is to get household paper manufacturers, tissue processors and tissue customers to agree on various tissue manufacturing terms and to facilitate the harmonization of testing methods. Each of the terms listed is briefly defined and illustrated if found useful. In writing this document, English was chosen as the original language. Then it was said that some expressions cannot be translated into another language. For these cases, English expressions are used.

1 範囲
This document establishes general principles for the use of terminology in the entire field of work for tissue and household paper products.

It allows the use of generic terms in industry and business.

It is specified that ISO 15755 is suitable for the detection of impurities and dents in tissue paper and tissue products.

ISO 287 applies to the determination of moisture content in tissue and household paper products.

2 規範的参照
There is no normative reference in this document.

3 用語と定義
この文書の目的のために, 次の用語と定義が適用されます.

3.1 Water Absorption

The ability of tissue paper (3.58) and/or tissue products (3.59) to absorb liquids

3.2 Absorption

3.2.1 Absorption capacity

The amount of liquid absorbed per unit mass of the sample under test

注記 1: Water absorption capacity is defined in ISO 12625-8.

3.2.2 Absorption rate

The mass of the liquid absorbed by the sample per unit time is determined by dividing the total mass of the liquid absorbed during a given period of time by the duration of the period

3.2.3 Absorption Time

The time required for complete wetting of the sample

[ソース: ISO 12625-8:201, 3.1]

3.3 Accelerated Aging

A procedure that quickly predicts changes in the characteristics of tissue paper (3.58) or tissue products (3.59) that occur over a longer period of time under normal conditions

注記 1 This is particularly the case for wet strength tissue paper or tissue products whose wet resistance increases over time. An accelerated aging procedure for determining wet strength is specified in ISO 12625-5.

3.4 Apparent packing density

The mass of tissue paper (3.58) or tissue products (3.59) per unit volume is calculated from its gram weight (3.28) and expanded thickness (3.10)

注記 1: It is determined by dividing the gram weight of tissue paper or tissue product by the thickness determined on the tissue.

[ソース: ISO 12625-3:214, 3.4]

3.5 Paper Towel products for outdoor use

AFH Tissue products

Paper towel products for institutional and industrial markets (3.59)

例: Tissue products used in hospitals, restaurants, hotels, offices.

3.6 Base Paper

A single sheet of tissue paper produced as a semi-finished product and intended to be converted into a finished product

3.7 Substrate forming

Wet-formed coils between one or two consecutive wires or between one wire and felt produce endless sheets of paper with a gram weight (3.28), usually between 10 g/m2 and 50 g/m2

3.8 Brightness

3.8.1D65 brightness

The intrinsic radiance (reflectance) factor measured using a reflectoscope with the properties described in ISO 2469, equipped with a filter or corresponding function with an effective wavelength of 457nm and a half-peak bandwidth of 44nm, and adjusted so that the UV content of the radiation incident on the sample under test corresponds to the UV content of the CIE standard light source D65

[ソース: ISO 2470-2:2008, 3.4, 修正済み — the entry symbols R457, D65 and note 1 were deleted.

3.8.2C brightness

ISO輝度

The inherent diffuse radiation (reflectance) factor measured using a reflectoscope with the properties described in ISO 2469, equipped with a filter or corresponding function with an effective wavelength of 457nm and a half-bandwidth of 44nm, and adjusted so that the UV content of the irradiation incident on the sample under test corresponds to the UV content of the CIE source C

[ソース: ISO 2470-1:2016, 3.4, 修正済み – Added the preferred term “C brightness” and deleted the entry symbol R457 and note 1.

3.14.1 International laboratory color space

Three-dimensional approximate uniform color space, by drawing rectangular coordinates L*, あ*, b to produce *

注記 1: The quantity L* is a measure of the brightness of the test piece, where L* = 0 corresponds to black and L* = 100 is defined by a perfect reflection diffuser. Visually, the quantities a* and b* represent the red and green axes and yellow and blue axes in the color space, それぞれ, making

— +a* is a measure of the redness of the test piece,

– −a* is a measure of the greenness of the test item.

— +b* is a measure of the degree of yellowing of the test item, そして

– −b* is a measure of the blueness of the test component.

If both a* and b* are zero, the specimen is gray.
