WEARER TRIALS

PURPOSE

The purpose of this procedure is to assess the wear ability and comfort of a garment.

SCOPE

This procedure applies to all styles.

RESPONSIBILITY AND AUTHORITY

The Technical Dept. at Head Office is responsible for ensuring that this procedure is carried out. 

PROCEDURE

  • The Gmt. Tech. Mgr at Head Office issues a gmt. along with a wearer trial form to the participant.
  • The participant wears the garment for a total of fifty hours and fills in the wearer trial form.
  • Head Office then assesses the wearer trial form to establish certain points.  This is then sent to the Factory and a copy is kept in the style file.
  • If there are no problems in these first fifty hours the participant is then issued another wearer trial form and asked to carry the trial on for a further one hundred and fifty hours.

Description

  • Weight of individual rolls measured on a calibrated scale with accuracy to the nearest tenth of a pound. 
  • Core weight (tare weight) to be considered ½ pound unless otherwise agreed.
  • Maximum roll weights to be stated in contract and/or purchase order.  They can vary by program, cutting facility, etc.
  • The weight of the fabric roll will not vary more than +/- 5% from the style specification weight. 
  • Shipping weights are based on lot or batch averages.
  • Roll Weights outside the +/- 5% variation are not to be rejected unless they are substantially beyond the 5% variation.
  • Fabric weight is quoted in terms of ounces per square yard, ounces per linear yard, grams per square meter and fabric yield.  In the case of open-width fabrics, the standard weight is based on the overall width of the fabric.
  • Ounces per Square Yard is the area weight of the fabric.  The oz/yd2 is taken by weighing the known area of a test fabric and calculating the ratio of weight in ounces to one square yard of the same fabric.  (see fabric specifications and test methods)
  • The fabric weight for most styles is guaranteed to be within plus or minus five percent (+/- 5%) of the standard ounces/square yard (oz/ yd2).  Ex: If the standard ounces per square yard is 5.5, the tolerance would be 5.22 to 5.78 oz/yd2.

Conclusion

Yield is the actual number of yards shipped divided by the total pounds shipped.  Tolerance on yield is also +/- 5% of total lot or shipment.  End of Yarn Testing Machine post

Sampling and Traditional Parameters

Installing light sources close to the work place is potentially profitable in case there are variations in the illumination required in the halls. In storage facilities this is usually not an option. Installing light switches in each hall and even over each working place is applicable when there are a number of halls for different production processes. It is not similar to Tubeless Lab Dispenser
The pay back time of this measure is usually between 1 and 3 years.
The International Commission on Illumination (CIE, http://www.cie.co.at/cie) and the International Standard Organization ISO have jointly published a standard governing lighting for indoor work places, taking into account energy efficiency. This standard ISO 8995:2002/CIE S 008/E:2001 called “Lighting of Indoor Work Places” may be obtained The member price is USD 51, whereas the list price

Flow Meters The facility shall have, at a minimum, functioning flow meters are the input and output points of their wastewater treatment facility.

Applying Single Desizing

Cellulosics and their blends with synthetics could be desized, scoured and bleached in a single stage. This could reduce the processing time by a considerable extent, apart from reducing the water consumption and wastewater generation.

This measure has been implemented in number of units in India, particularly for the batches where the final dyed product is of a dark shade. In these situations no adverse effect on the quality was observed. The improved environmental impact is due to the fact that all three processes could be carried out in just one bath (instead of three different baths for thrice the duration and having rinses in between). Furthermore, as in earlier mentioned options, the industry concerned would need to make a few trials before commercial implementation.
Reduced process time and energy
Reduced water consumption
Reduced wastewater generation
Reduced cost of effluent treatment
Applicable for cellulosics and their blends only. Combined process for desizing, scouring and bleaching is particularly suitable for fabrics in dark shades, where the bleaching requirement is low. However, this could also be applied for medium shades, depending on the efficiency of the combined process.
The savings are obvious because of the reduction in the number of stages as well as the process time and water.

Conclusion

Tube Dispenser -Illegal discharge of wastewater or bypassing treatment facilities will not be tolerated

What is Micro Sieve? What is Safe and Efficient Chemical Use

Micro Sieve

  • Micro Sieve – For filtration of particles/microcapsules Membrane Size range: Ito 150 mm, Membrane Thickness: 0.1 to 5 gm
  • Pore Size range: 0.1 to 100 gm
  • Membrane Material: Ceramic or equivalent Temperature Resistance: -50 to 700°C Inert to organic solvents. We sale Chemical Inventory Management System

Description

Open-Width Styles – The cut able width is guaranteed to be within two inches (2”). The cut able width is quoted as the minimum cut able width plus two inches. For example, a quoted cut able width of 60-62 inches means that 60 inches is the minimum cut able width and that 62 inches is the maximum cut able width.

Tubular Styles – The cut able width is guaranteed to be within one inch (1”). The cut able width is quoted as the minimum cut able width plus one inch. For example, a quoted cut able width of 30-31 inches means that 30 inches is the minimum cut able width and that 31 inches is the maximum cut able width.

Body-Size Tubular Styles – Some body-size styles are quoted as being a standard width. The body-size tolerance is plus or minus half an inch (+/- 1/2”). For example, a quoted body-size width of 24 inches means that 23.5” is the minimum cut able width and that 24.5” is the maximum cut able width.

Yards are recorded as measured using a machine with a calibrated yardage meter. Measuring the yards on a cutting table is not an acceptable means of measuring fabric yardage.

Yardage is considered accurate if within +/- 1.5% of the total ticket yards on most styles and +/- 3% on ribs and styles containing spandex.

Reasonable consideration will be given to consistent shortages or deviations.

25 yards is the minimum individual roll size.

Individual roll pieces may be lapped rather than re-sewn. The pieces must be sewn together on jumbo rolls and Prepared-For-Print (PFP) rolls.

The number of splices or seams per roll are as follows:

Fleece or Terry Fabrics – Two splices or seams per roll. Each spliced piece must be at least five yards.

Prepare-For-Print (PFP) Fabrics – All splices will be sewn. Two seams per 100 yards. Each piece will be at least 25 or 40 yards between seams depending on the greige roll size for that style.

All Other Fabrics - Three splices or seams per roll. Each spliced piece must be at  least 10 yards.

Height – This is the short side of the collar and is measured in the center from the inside ridge at the base of the collar to the top edge.

Width – This is measured in the middle of the collar parallel to the longest edge. Because the collar is basically a rib construction, the stretch in this direction is considerable.

Collar and Welt Tolerances

        Collars     H=  +/- 1/4”
                W=  +/- 1/2”

        Welts       H=  +/- 1/8”

Written instructions will help to reduce the usage of chemicals and improve health and safety in your company.

Safe and Efficient Chemical Use

Provide easily accessible, simple to understand instructions for chemicals used at your facility. These instructions should provide information on how to handle chemicals, how to deal in case of accidents and how to safely dispose of chemicals. Instructions should at least include information on:
• Identification of the substance
• Use of the substance
• Labelling symbol for chemicals
• Handling and storage, specific use and associated equipment
• Exposure controls/personal protection
• Instructions in case of accident and accidental release measures
• Important health, safety and environmental information
• Disposal instructions
Associated with the implementation of the instructions should be training with the employees. It is important to explain the instructions and to give
This measure will help to avoid accidents, which can have important environmental impacts and facilitate efficient usage of chemicals. A better handling of chemicals will also improve health and safety conditions for the employees.
