Zipper Knowledge

Question1Will any dye transfer occur when white (light color) fabrics are used together with red (dark color/bright color) zippers?
AnswerPlease confirm with our sales persons when you place an order. We are able to decrease the chances of dye transfer by improving the color fastness. Please note this might result in greater color difference. Additionally, a piece of lining cloth shall be used for separating the zipper from the fabric when sewing is performed.
Question2Will any dye transfer occur with the tapes?
AnswerGenerally speaking, the color fastness reaches Grade 4 for most colors and Grade 3.5 for some special colors, for example, bright red. However, dye transfer would occur as a result of the chemical reaction that will easily take place between the disperse dye molecules in the zipper tapes and the plasticizer, adhesive agent, oiling agent contained in such fabrics as vinyl chloride that contains DOP, synthetic leather or fabrics whose surface is coated with resin. Hence, a piece of lining cloth shall be used for separating the fabric from the zipper when sewing is performed and the products in custody or storage should be separated from each other using the leatheroid.
Question3How to select a metal zipper according to the thickness of the fabrics?
AnswerA metal zipper with 4#+ square teeth is required for fabrics thicker than 12 ounces (340.2 grams), which can reduce the possibility of damage caused to the zipper. Metal zippers with 3# or 4# common teeth would easily break down in use in this case, with the teeth dropping off, splitting, etc.
Question4Can any washing technique be applied to the metal zippers?
AnswerDue to the diversity and complexity of the technologies involved in the washing process, customers are required to provide the washing method of the products for our assessment when placing an order.
Question5Would the central seam in nylon zippers with reverse slider be the same as that in the invisible zippers?
AnswerIt is inadvisable to lay too much emphasis on the central seam, which may result in abnormal opening and closing of the zippers. Generally speaking, the central seam ranges from 0.3mm to 0.6mm.
Question6Will any color change occur if the nickel free platinum accessories are used together with the woolen products?
AnswerColor change will occur easily when the nickel free platinum accessories are used together with the cotton or woolen products, such as getting black, yellow, etc., which can be mainly attributed to the chemical reactions that take place between the residues introduced in bleaching, processing, etc. In spite of the protective treatment applied, the chemical reactions cannot be completely eliminated. To prevent any chemical reactions, please make sure the fabrics have been fully cleaned to a neutral state prior to batch production.
Question7Would you please explain the great color difference at the front and back of the water resistant zippers with adhesive tape?
AnswerDue to the characteristics of TPU, special reinforcement treatment is applied to ensure its firmness of binding with the tape. The complex reaction involved in the recombination process leads to darker colors. The darker the color, the greater the difference. In fact, there has not been any technology that can break through the great color difference by far. Please confirm with us before you place an order. Besides, please try to select from the 36 types of colors that are available for use.
Question8How do you control the shrinkage rate of the zippers?
AnswerThe shrinkage rate falls below 4% and 1.5% for the nylon chains and finished products respectively, exclusive of some special products. The former also applies to the coated zippers, colored teeth & tapes, 3# nylon zippers as well as invisible zippers.
Question9Can the metal zippers match the spray painted sliders?
AnswerNo. The paint will easily peel off due to the internal friction, which in turn will lead to the exposure of the zinc alloy. And fading will occur as a result of the electrolysis reaction that takes place easily between the exposed zinc alloy and the copper contained in the laundry detergent during laundering.
Question10Do you manufacture molded & coated nylon zippers with open end (O/E) or close end(C/E)?
AnswerNo. This is actually one of the very few types of zippers that we don’t manufacture.

Button Knowledge

Question1What materials are your buttons made of?
AnswerOur buttons can be manufactured out of metal, polyester, plastic and natural materials.
Question2What does L stand for?
Answer"L" stands for Ligne, which is a measurement system used for determining the size of buttons in the industry. You can easily convert inch/millimeter into ligne and vice versa. Take a look at our conversion chart here.
Question3What button sizes do you provide?
AnswerVarious sizes are available, dependent on the type of button.
Question4How many holes can you design for flat buttons?
AnswerFlat buttons are also referred to as sew-through buttons. These buttons have holes in the middle, through which the thread is sewn to attach buttons to the garments. Generally speaking, we can manufacturer flat buttons with either 2 holes or 4 holes, with a wide variety of designs available for selection.
Question5Can your buttons be attached to knitted fabrics?
AnswerPlease send your fabrics to us before placing an order so we could double check whether they are applicable or not.
Question6Can buttons be attached on uneven surface/thickness?
AnswerAttachment should NOT be made on uneven surface/thickness, which could tear the fabric and result in weak fastening/unfastening performance or detachment.
Question7Can buttons can attached to thin fabrics?
AnswerButtons can be attached to such fabrics whose thickness ranges from 0.5mm-2mm. Attachment should Not be made on single-layered fabrics, in which case, folding or interlining is recommended to ensure secure attachment.
Question8Can your buttons withstand the washing treatment?
AnswerIt depends. Please double check with us. Please follow the instructions below during the washing process.

Please use neutral detergents. Avoid such corrosive chemical detergents as strong acid, strong base, etc., whose corrosiveness could result in the color fading, paint chip-off and deformation of resin buttons, metallic buttons (copper/alloy) and shell buttons.

Attach the buttons after the washing treatment if applicable, as the chemical reactions involved in the washing process might lead to the corrosion and color change of buttons, regardless of the special treatment applied.
Question9Is it fine to iron buttons?
AnswerMake sure the iron does not come into direct contact with the buttons when ironing. Direct ironing will lead to the breakage or distortion of plastic buttons and result in the scratching or deformation of metallic buttons. Place a sheet of cloth over them before ironing.
