Product Usage and Warnings

Dyeing and Washing

Washing or post-processing such as bio-stone washing, bleaching, dyeing on clothes discolor or abrade metal accessories, damage the varnish or cause stains on the fabric.

1 Dyeing On Clothes:

T&T recommends attaching all metal accessories after the fabric dyeing process. This is to prevent corrosion of the metal coating and/or possible chemical reactions that could cause staining of the apparel fabric.

2. Bleaching:

Since chemicals and similar products used during bleaching may cause chemical reactions that cause corrosion and/or discoloration of metal accessories, all metal accessories should be attached after bleach washing. In addition, chemical residues left on the washed fabric after washing can cause changes and problems in metal accessories.

3. Stone/Enzyme Washing:

All metal accessories should be installed after stone/enzyme washing, as stone/enzyme washing can cause wear and corrosion on metal accessories.

Chemical Conditions

Metal accessories often react with chemicals such as acids, alkalis (bases), oxidizing agents, reducing agents and sulfides, often forming colored salts. These chemicals cause discoloration and corrosion on metal parts. These chemical reactions take place more easily in hot and humid conditions. For example; such a reaction is likely to occur if the products are pressed with a steam iron after planting and immediately wrapped or packaged in plastic bags for a long time. Reactive dyed fabric or sulfur-dyed fabric causes discoloration and staining of metal accessories. Our company cannot be held responsible for color changes and deformations that may occur due to these reasons.

1 Sulfur Dyestuffs:

The sulfur dye treatment causes corrosion on the protective varnish on all coatings, which can lead to corrosion of the metal accessory and/or staining of the apparel fabric.

2. Reactive Dyes:

The reactive dye process causes corrosion in all metal coatings, especially under extreme or prolonged humid conditions. Causes possible corrosion of metal and/or staining of apparel fabric.

3. Wool Knitted Products

When metal accessories are fastened to bleached wool knitted products, color change may occur in metals.

Generally, woolen products are whitened by the following methods:

- An oxidizing bleach (hydrogen peroxide, etc.)

- A reducing bleach (hydrosulfite, etc.)

Especially after the treatment with hydrosulfite or chlorinated substances, if adequate washing or neutralization is not performed, gas (chlorine gas or sulfur dioxide gas, etc.) may occur. These hydrosulfide and chlorinated substances can also react directly on the metal in humid conditions. For example, if woolen products are put into bags immediately after pressing with an iron and kept as is, various chemicals and gases will cause color changes in metal accessories.

Proposed solutions;

■Use thoroughly washed, neutralized and dried woolen fabric.

■Allow sufficient time before packaging after the products have been pressed with an iron.

4. Leathers

Residual tanning agents or acids used in leather tanning can cause a discoloration of metals. The leather undergoes potent chemical treatments in the tanning process, and residues of such chemicals tend to discolor metallic parts.

Tanning agents such as sulfuric acid and other mineral acids, chromium compounds, tannic acids and aldehyde compounds are used. Since the main component of the leather is animal protein, the leather cannot get rid of these tanning chemicals naturally or easily, and usually, a large amount of chemicals remains. When this type of leather comes into contact with metal accessories, it may cause discoloration in metals over time in humid environments. 

Proposed solutions;

■Use adequately washed and neutralized leather after tanning.

■Perform preliminary tests.

■Please consult T&T sales office for products to be used on leather.

Stowage/Storage Conditions

All accessories, fastened or not, should be stored at room temperature and in a damp environment. Due to natural reasons (sudden and high temperature changes, excessive humidity, etc.), product colors may change color tone over time. Metal parts may rust depending on storage conditions. Rusty and corroded metals have a risk of staining the textile product, so the products should be kept at low humidity.

Do not use rubber bands to bind metal accessory bags or items with fastened accessories, as the sulfur in the rubber bands can cause metal parts to rust or discolor. (This issue occurs even when the rubber band is used on a plastic bag.)

Avoid using/storing accessories in a location subject to pressure, impact or abrasion or other conditions that could cause deformation and/or damage to the accessory. Especially the products with hanger coating are high surface quality and sensitive products. During use and storage, it should not be exposed to the conditions mentioned above.

Our company cannot be held responsible for the deformations that will occur due to these reasons.

Ironing and Steam Press

No metal accessory should be exposed to direct iron contact and steam. Direct ironing causes scratches and deformation of metal parts. 

Fastening and Application

Data Sheet (fastening suitability) tests specific to each order are carried out by our company. Before starting the mass production (in the sample stage), Data Sheet tests should be requested and the products produced according to the report result should be fastened according to this test report. During mass production, the fastening areas and the Mock-up seams and the number of fabric layers must be produced exactly the same.

It is especially recommended not to use a manual fastening machines with pneumatic and magnetic coils for healthy fastening of metal accessories. If the pressure is too strong, problems such as deformation, breakage, hard or easy closing-opening movements may occur in metal accessories.

Especially since click products are sensitive and functional products, they should be fastened with a T&T fastening machine and a T&T fastening tool. Otherwise, inconsistencies may occur in the functional properties and binding strengths of the product.

T&T fastening dies specific to accessories should be used in the fastenings of our accessories. Fastening molds should be checked regularly, and molds that have lost their properties and are deformed should not be used.

Needle Detector Applications

Products made of some stainless steel raw materials, zamak products according to their size and weight, give a signal in the metal detector. For this reason, when accessories produced from these raw materials are used, it is recommended to check for broken needles before fastening accessories.

Needle detectors not only detect magnetizable metal components (iron-based stainless steel, cobalt and nickel-based coatings from which the broken needle is made); The abundance of non-magnetizable metal components on the controlled products, the geometric shape (circular pullers, closed form belt buckles, salopet buckles ...) and size of the accessories, the high electrical conductivity of materials such as pure copper, the wet processes such as printed labels and stone washing affect the needle detector test result. The geometric shape of the accessories (circular pullers, closed-form belt buckles, salopet buckles…), the high electrical conductivity of materials such as pure copper affect the result by creating an induction field in the products. The signals generated in these cases do not indicate that the products contain ferrous material.

As shown in the image below, the way the product is passed through the detector (in folded products, metal components come closer to each other and increase the metal density, …) affects the result of the needle detector test. Therefore, as Timay &Tempo, we kindly request that our products pass through the detector one by one.

If the needle detector gives an alarm during the control of accessories with heavy metal components, the user may hesitate; because it cannot be clearly understood whether the detector has caught the broken needle that may have remained on the product or whether it is affected by the metal density. In such cases, hand detector control should be applied.

Suitable product selection

Make your T&T product selection only after adequate checks have been made. The strength of T&T products depends on the fabrics used, its texture, weave thickness, location of the seam line and other factors you need to consider. For more information, please contact your T&T sales representative

Choose the right metal accessory for your application from our product range. Your T&T sales representative can help you understand the variety, sizes, strengths and features of our products. 

Opening and closing hardness may vary depending on the coating used in the snap fastener groups. Especially oxidized coatings cause hard opening and closing.

Oxidized accessories cause stains on light-colored fabrics. Therefore, special varnishing is applied to the accessories to be used on light-colored fabrics. To perform the varnishing process, it is necessary to give fabric color information when ordering.

Some products have mold marks (the line formed when materials are combined in the mold during production). This mark is not a defect, damage or crack. Please check carefully before using the product.

If there is a pattern/logo in the center of buttons, rivets, snap head and similar products, traces are formed on the product patterns after fastening. During the logo design, care should be taken not to ask for a logo in the product center.

The color to be selected from our color charts may vary depending on the product type, logo design and coating conditions. The perception of color difference in accessories occurs as a result of light refraction due to changes such as logo/pattern, and dishedness.

Timay&Tempo will not be responsible for any problems that may arise in cases where the above information is not followed.
