THE NEW ZEALAND WOOL INDUSTRY SPECIFICATIONS FOR WOVEN CAPLESS WOOL PACKS MADE FROM MULTIFILAMENT NYLON YARNS

DECEMBER 1993

1. INTRODUCTION

1.1 TITLE:
These Standards and Procedures shall be called the “New Zealand Wool Industry Specification for Woven Multifilament Nylon Capless Wool Packs”.

1.2 APPLICATION:
This Specification replaces all previous Specifications for Woven Multifilament Nylon Capless Wool Packs. All New Zealand Multifilament Nylon Wool Packs supplied to New Zealand after 12 December 1993 will be required to meet this Specification.

2. STANDARDS

2.1 FABRIC:

2.1.1 The pack fabric shall be woven from undyed high tenacity multifilament nylon yarn having similar dyeing characteristics to wool. Each individual filament shall be no greater than 10 decitex.

2.1.2 The pack fabric shall not contain any loose ends of yarns and the pack itself shall be free from cut ends of yarn, thread, flakes of anti-slip coating material, or other foreign matter.

2.2 MASS:
The finished pack shall have a mass of not more than 1.70 kilograms and not less than 1.30 kilograms.

2.3 DIMENSIONS:

2.3.1 Each of the pack flaps as measured from the top of the side seam shall be not more than 470 millimetres and not less than 450 millimetres.

2.3.2 Each of the side seams of the pack shall extend not more than 995 millimetres and not less than 965 millimetres from the base seam.

2.3.3 Each of four base dimensions, as measured from the side seams shall be not more than 715 millimetres and not less than 685 millimetres.

2.4 STITCHING REQUIREMENTS:

2.4.1 The pack seams shall be sewn with an undyed multifilament nylon sewing thread in which each individual filament is not greater than 10 decitex.

2.4.2 The ends of the sewing threads shall be cut and permanently heat sealed so as to prevent unravelling of the threads.

The cut edges of the pack seams and of the flaps shall each be permanently heat sealed without visible fraying. In addition, the cut edges of the flaps shall be folded twice and hemmed.

2.5 PACK MANUFACTURER’S LABEL:
A permanent label 100 millimetres by 50 millimetres and manufactured from a non-fibre shedding material must be affixed to a side seam of each pack, in such a manner that the following details are clearly visible on the outside:

Manufacturer Identification

Brand Name
Batch Number/Coded Year of Manufacture

2.6 BALE IDENTIFICATION LABEL:

The specifications for the attachment of the bale identification label to New Zealand capless wool packs are attached as Appendix A.

2.7 BATCHES:

A production batch is defined as:

• a quantity of wool packs not exceeding ten thousand in number;
• produced from the same composite raw materials, and
• manufactured within a specific factory.

2.8 BALE IDENTIFICATION:

Properly prepared for shipment is defined as:

• a production batch of wool packs which have been pressed into bales;
• wrapped with an outer covering of material which is of the same type as the packs, and
• legibly marked with the production batch number and appropriate bale number.

3. STANDARDS FOR PACK AND PACK FABRIC

3.1 STANDARD OF BREAKING LOAD:
When tested in accordance with the procedure specified in paragraph 4.1 below the fabric of the pack shall have a breaking load of not less than 250 kilograms force in the warways direction and not less than 250 kilograms force in the weftways direction.

3.2 STANDARD OF SEAM STRENGTH:
When tested in accordance with the procedure specified in paragraph 4.2 below, the pack seams shall have a strength of not less than 100 kilograms force on side/side seams and not less than 100 kilograms force on side/bottom seams.

3.3 STANDARD FOR TEARING STRENGTH:
When tested in accordance with the procedure specified in paragraph 4.3 below, the fabric of the pack shall have a tearing strength of not less than 45 kilograms force in the warpways direction and not less than 45 kilograms force in the weftways direction.

3.4 STANDARD OF STABILITY TO EXPOSURE TO ULTRA VIOLET RADIATION:
When tested in accordance with the procedure specified in paragraph 4.4 below, the fabric of the pack after exposure for 168 hours shall have a breaking load of not less than 250 kilograms force in the warpways direction and not less than 250 kilograms force in the weftways direction.

3.5 STANDARD OF SURFACE FRICTIONAL PROPERTIES:
When tested in accordance with the procedure specified in paragraph 4.5 below each side of the pack fabric shall have a force of not less than 3.5 Newtons and not more than 5.5 Newtons in both the warpways direction and the weftways direction.

3.6 STANDARD OF HEAT STABILITY OF THE ANTI-SLIP COATING:
When tested in accordance with the procedure specified in paragraph 4.6 below, the anti-slip coating applied to the pack fabric shall not melt or show any adhesion between wool and the fabric after five minutes heating at a temperature of 110 degree Celsius.

3.7 STANDARD OF LOAD/EXTENSION PROPERTIES:
When tested in accordance with the procedure specified in paragraph 4.7 below, the fabric shall have an extensibility of not greater than 12 percent in the warpways direction and not greater than 12 percent in the weftways direction.
