Yarn-paper is a special-purpose paper commonly used to make yarns in textiles to protect the yarn and facilitate storage and transportation. Yarn paper is mainly made of wood pulp and waste paper, which has good flexibility, water resistance and tear resistance.

検出性能
The performance test of yarn paper usually includes the following aspects:

Detection of base weight: The base weight per square meter is calculated by weighing the weight of a sample of yarn paper of a certain size. Use a precision electronic scale or balance for measurement.

厚みと均一性の検出: by measuring the thickness of the yarn paper using manual or automatic thickness gauges, and by laser measurement or machine measurement methods to detect uniformity. 手動厚さ計は通常、手持ち式厚さ測定器を使用します。, 自動厚さ計は通常、レーザー三角測量を使用して厚さを測定します, 均一性の検出方法はマシンビジョンシステムを使用して実行できます。.

強度試験: through the use of strength testing instruments, 電子引張機など, multi-functional testing machine, 等, to measure the tensile strength of the yarn paper, 圧縮強度およびその他の指標.

原紙性能試験及び試験装置

Testing of rupture strength and flexural strength: By using rupture strength tester and flexural strength tester to measure the performance of the yarn paper such as rupture strength and flexural strength.

Wet strength testing: By using wet strength testing instruments, such as wet strength tester, environmental humidity test box, 等, to measure the strength of the yarn paper in a humid environment.

Tensile strength and elongation at break detection: by using a tensile testing machine to measure the tensile strength and elongation at break and other indicators of the yarn paper.

包装性能試験: By using packaging performance testing instruments, such as breakage tester, water tightness tester, 等, to measure the packaging performance of the yarn made of yarn paper.

環境保護試験: through the use of environmental testing instruments, 揮発性有機化合物試験器など, 重金属テスター, 塩化物イオン測定器, 等, 揮発性有機化合物の含有量を測定する, ヘビーメタル, chloride ions and other harmful substances in the yarn paper.

Testing instrument
The performance testing of yarn paper usually requires the use of some special instruments and equipment, including but not limited to the following:

Base weight detector: Used to measure the weight of a certain size of yarn paper sample, calculate the base weight per square meter.
