Fabric sourcing materials testing

In 1980 the Consumer Protection Act (15) required manufacturers to take reasonable steps to ensure that fabric -soft infill composites of domestic furniture resisted the cigarette test of BS5852 Part 1. These regulations did not apply to rouchings, trims to seat platforms etc. but only to the primary upholstery composites. The Consumer Protection Amendment of 1983 required specified children s furniture containing cellular materials had to resist Source 5 of BS 5852 Part 2. (16)... 

ALL FILLING MATERIALS EXCEPT PU SHEETS OR BLOCKS. These are tested against ignition source 2 which is a butane flame, approximately 120 mm high and applied to the FR polyester fabric covered filling for 40 seconds(Table VII) to BS 5852 part 2. This applies to all loose foam and non-foam filling when tested singly. 

All filling materials are specified by ignition tests to BS 5852 Part 2 and composite non-PU foam mattress fillings to BS 5852 Part 2 and BS 6807 for seating and mattress applications respectively with a flame retarded polyester fabric. Different ignition sources, constructions and pass/fail criteria are used to differentiate between "acceptable" and "unacceptable" materials. 

To prepare a painted fabric for comparative purposes, small bands of ferrous oxide, an alizarin/purpurin mixture, ground up bloodroot (Sanguinaria canadensis L.) and bedstraw (Galium verum L.) were painted on linen fabric (Testfabrics L-57). As carriers or binder for the pigment colorants to be painted on the fibrous materials, beef fat was used as a substitute for bear grease and egg white was used as source for albumin. The various combinations of these materials were mixed and painted on areas of the test fabric as outlined in Table III. The painted test fabric was left to diy for 24 hours.

CPB Materials. Various types of silane crosslinkers were employed to fabricate crosslinked polymer blend (CPB) dielectrics in this study (Fig. 4). The reactivity of each crosslinker was tested via in situ NMR kinetic studies. The CPB dielectrics were fabricated on various substrates using mixture of polymer and crosslinker solution via spin-coating and gravure-printing. Organic semiconductors and source/ drain electrodes were vacuum-deposited to complete the OFET device. Dielectric and OFET properties were measured under vacuum and ambient as described previously. 

There are three important sources of data and information on RPs. Obtain data from products your organization previously fabricated there is the data sheet compiled by a manufacturer of the material and derived from tests conducted in accordance with standardized specifications. If suppliers data were to be applied without a complete analysis of the test data for each property, the result could prove costly and embarrassing. Final source is preparing your own test specimens and conducting your own tests. Either one or both specimen preparation and test evaluation could be conducted by an outside source. If the fabricator prepares the specimens a duplicate of the fabricating process to be used will be produced or as close to the process as possible. The amount and degree of testing is usually related to factors such as (I) if a prototype is to be prepared and tested and (2) product requirement such as safety. 

The text is organized and written with useful information in the World of Reinforced Plastics to provide a source and reference guide for fabricator, mold maker, material supplier, engineer, maintenance person, accoimtant, plant manager, testing and quality control individual, cost estimator, sales and marketing personnel, new venture type, buyer, user, educator/trainer, workshop leader, librarian/information provider, lawyer, consultant, and others.
