1.2 Suggestions on how to sew  neoprene

SEWING ON A NOT LINED SHEET

When it's necessary to sew with sewing machine a not lined neoprene sheet, you will wonder how to avoid the rubber from getting stuck in the sewing machine mechanism.

The rubber in fact makes friction on the roller, the sheet does not flow, the thread is knotted ... and the seam is difficult, if not impossible.

To overcome this problem you can:

* Use a sewing machine with walking foot

* Interpose between the rubber and the roller of the machine a sheet of tissue paper

* Use special silicone spray that make slippery the rubber and needle.

 

VARIOUS TYPES OF SEAMS

OVERLOCK

Overlock seam, in our industry, is typically used for two types of applications:
- Finishing of edges
- Fast assembly of very low thickness panels

Finishing: in addition to a nicer appearance, Overlock seam finishing edge / rim (of a sleeve, a pant, hood ..) protects the product from small delamination and fraying.

Assembly: many neoprene accessories are packaged with this seam, which does not require the pre-pasting of the parties. Overlock  seam does not guarantee any resistance.

FLATLOCK

It 's a flat seam, very resistant also suitable for thin neoprene. It 's very decorative but isn't waterproof; It can be made simultaneously using different colored yarns.

BLINDSTITCH

Is the typical stitching for neoprene products: the needle does not completely perforate the neoprene, so the seam is waterproof and the chain structure ensures elasticity.

WELDED

There are no seams but neoprene is only glued.

 

2. Why our neoprene is not made in Italy?

Despite being big fans of Italian origin, our neoprene is made in the Far East (Taiwan, Hong Kong, Japan ...).
Here's why ...

First we must specify that  neoprene sheet is generally made from foam (CR) and by any laminated fabrics on one or both sides, or, in special cases, also inside.
The main CR foams that we sell are "oil free", that is to say they are made without petroleum derivatives, as to confirm the to pursuing the objectives of compatibility with the environment and health.

The product sector in which we operate requires materials with certain characteristics of quality, comfort, durability and softness, and the producers that we have selected are all engaged in the research and development of specific products for these niche markets.

The neoprene produced in Europe is mainly dedicated to the industrial market, and although geographically more palatable, has characteristics that make it unattractive in the water sports field, clothing and accessories.
The substantial difference is the quality of the fabric lamination: in the watersports field, the seal pasting of the fabric to the foam is crucial, due to the frequent use of the products in aggressive environments (for example, sea water) .
For this reason, manufacturers of neoprene sheets that we market, give top priority to the research of increasingly high performance adhesives and increasingly oriented to the environment.

They are currently in test phase the "toluene free" glues, which represent a decisive step towards more green products.

3. How to measure the zippers

MEASURE A: measurement from one edge to the other (length + zip fasteners).

MEASURE B: chain measure (egde excluded).

MEASURE C: is the actual measure of the space of use.

 

3.1 Instructions for pasting a TIZIP zipper

Treat the polyurethane tape applying PRIMER 41 brush. Wait 15-20 minutes; then apply the PLASTEK 82 adhesive  supplemented with 5%  DESMODUR RFE activator.

If the zipper is applied on neoprene, apply the  PLASTEK 82 adhesive  on neoprene supplemented with 5% DESMODUR RFE activator .

If the zipper is applied on a trilaminate fabric, clean the surface of the trilaminate that has to be paste with EKOSOL solvent; after 5-10 minutes apply with a brush PRIMER 41 and after  60 minutes, repeat the application. After another 60 minutes from the second application, use PLASTEK 82 adhesive  supplemented with 5%  DESMODUR RFE activator.

In both cases mentioned above, to reactivate the glue after the complete evaporation of the solvent, the supports are reactivated by a heating source, coupled and pressed.

4. TRILAMINATES

4.1 Seams or heat seals?

Trilaminate is sewed (so panels stay attached) generally with linear machines with one or two needles, and then seams must be sealed (recommended Aquasure), since sewing will make lose water resistance.

Thermal pasting can be done only on certain fabrics (type Aquamax ...) and only if you have suitable equipment and compatible tapes.

Surely it's an hazard to heat-seal wetsuits for diving ... because the tapes rarely guarantee absolute impermeability during immersion.
The heat-sealing is good for all surface water sports ... where there are no particular "pressures."

4.2 TRILAMINATES ARE WATERPROOF?

The trilaminates that we sell are all 100% waterproof; also Aquamax and Aqualight trilaminate that are breathable ( air pass through but not water).

For underwater applications Aquamax  waterproof membrane may be too delicate over time, so it would be more "sustainable" to use trilaminate with butyl; for drysuits and water jackets for canoeing and sailing, however, it is definitely recommended Aquamax .. already used by various brands in that market.
