Some often-quote terminology for the fabric performance: 

 

 

1. WP ( Waterproofness )- regular test standard AATCC 127 / ISO 811

Please view our Aqua-Shield items and contact us for any further question:

Lots of glove and mitten wearers get wet hands in winter. It is unwise to comment that it is because their hand wears are so “ warm “ that hands get sweaty. Some waterproof bag-installed gloves in the dry days also get wet hands.

Reasons of “ wet ” hands come from basic facts:

FIRSTLY

our hands, as part of the human body, generate constantly micro-vapor and transmit to the outside of the skin. All the vapor gather in the insulated environment without a good outlet. Therefore, the moisture in the gloves and mittens makes a sweaty hand.

SECONDLY

Water droplets can gradually seep from the seam of the over-laid fabric and the stitching holes on the shell in the manufacturing process. Despite that fabric is waterproof, the seam and holes make the glove not waterproof.

Having wet hands in winter is by no means a good experience.   It is complained a lot by the wearer as it intensifies the “ cold “   feeling of hand, meanwhile, the humidity of the micro-environment inside the glove can easily give birth to bacteria and microbe.  

The comfort properties of product waterproofness depend on its ability to transmit vapor and moisture from body preventing the accumulation of liquid on the skin, and to block the entry of water-droplets causing a wet hand.

 

 

 

 

 

 

                     To sum up, a good pair of gloves should keep your hand

Warm And Dry

Glove waterproofness depends on various elements:

An often-asked-question by our customer is if the glove is “ waterproof “.

If fabric has enough function of waterproof treatment of either coating or membrane,   which can resist temporally the water leakage and delay the seeping process, however, due to the stitching holes on the fabric, the water will eventually “ sneak “ inside.

It measures the maximum pressure from water that fabric can resist before water leakage appears on the fabric surface. Pre-wash and After-wash tests can have substantial difference.  The WP is achieved from the treatment on the backside of fabric like coating or lamination of membrane.

2. MAP ( Method Air Permeability )- regular test standard ASTM D737, ISO 9237

It ranks the property that air current pieces through the fabric. This represents the real meaning of “ breathable “.

3. W/R ( Water Repellent ) - regular test standard AATCC22, ISO 4920

The test sprays the water on the fabric and evaluate how much water is left in the form of drops that gather together and peel away easily.The W/R is achieved from coating on the fabric surface.here are different grade of W/R and DWP ( Durable Water Repellent ) refers to the treatment that can better withstand the washing and keep the performance.

4. MP ( Moisture Permeability ) - regular test standard ASTM-E96A

This evaluates the ability that fabric allows the moisture to pass through. Bigger figure shows higher standard.

The waterproofness of the glove comes from the finishing to seal the seam and stitching holes on the shell. There are several ways to make the gloves real “waterproof” by targeting on the causes on water leakage

We install a waterproof baggie with sewing tabs from which the interior one is to stitch with lining while the exterior is to stitch the shell.

Heat Taped seaming is widelyapplied on ski jackets and pants.The turning wheel on the machinemove and melt the sticky tape tocover along the stitching holes.But moving the wheel along drastic turns on finger tips arealmost not possible. Marblemannhas successfully developed theHeat Taping machine

Heat-sealing with membrane. is an advanced finishing combing both waterproof baggie and heat sealing. The baggie with sticky glue on both exterior and interior is put into the targeted product of shell and lining.

Among the above options: 

 

# A is widely used in production due to the lower cost and easier manufacturing steps.

 

# B is quite demanding in fabric, machine and operation skills, but it provides highest comfort when using together with removable liner.

 

# C is not yet technically mature for Marblemann to accomplish and we are continuing to watch this, hopefully to have positive progress in the near future.

Currently many ski gloves & mittens apply the individual waterproof bag to isolate the water, but in most cases, we still have wet hands. This can be attributed to quality and execution of the bag:    

 

a. if the baggie is breathable and how much breathable    

 

b. if the baggie has sewing tab to connect the shell and lining

Waterproof baggie is classified based on below listed properties, sometimes, they offset each other. For example,  higher breathable bag can be very tiny and soft affecting the tenacity and strength ( waterproof baggie can get broken in the manufacturing of turning from inside to outside as well as the glove shaping when glove is spread into the steaming board ) ; when we increase the thickness, the breathability figure decreases.  

Mis-evaluation on the quality of waterproof bag exits in some tests, which wrongly follow the request for garments. In fact, there might not be a specific test standard for the waterproof bag used on gloves and beanie.

Unlike garment or fabric for the garment, the tiny waterproof baggie is unable to carry on the same water pressure in W/P test. This is because consumers don’t wear waterproof bag alone or use it as a shell exposing to the open air, therefore, applying the same test standard on the waterproof baggie is incorrect.   Actually, since it is used under the glove shell to block the water, the reasonable way is also to test waterproof baggie under a thin layer of fabric

 

Applied to many ski gloves and mittens as well as outdoor headgear, Aqua-shield can offer and adjust based on your request and budget to maximize the product value.
