A：Ordinary zipper can be reciprocated for more than 500 times, and the plated tooth zippers can be reciprocated for 100-200 times at most.
Q：Why doesn't the zipper slide smoothly when it's opened or closed, or does it clamp the clothes?
A：When sewing the zipper, if the stitching is too close to the chain tooth, there is not enough space for the zipper to slide, so the zipper sliding will be blocked. So you shall leave enough space when sewing zippers.
If the fabric used is too thin or too soft for the zipper to hold the fabric, reinforce it with seams or core wires.
Q：What if the zipper parts melt during ironing?
A：When pressing zippers with an iron, be sure to line a layer of fabric on zippers. Please pay attention to the heat resistance of zippers (and the product itself).
Q：Why do metal zippers change color?
A：Metal parts may get corroded, which depends on their storage conditions. Corroded parts may contaminate the product , so the product should be kept in a place with low humidity.You should avoid sealed storage in plastic bags or cardboard boxes, and store with some air permeability (also note the effect of nitrogen oxides).
Please pay attention to the fact that using fluorine-containing cleaning products or touching fabrics that have been used fluorine-containing cleaning products can make metal parts fade.
Q：Why do wool or feather products change color while using zippers?
A：Wool or feather products are prone to have chemical residues (such as bleach) that cause the metal parts of the zipper to react when stored, leading to discoloration or corrosion. Neutralize properly and choose products that are not susceptible to chemical residues, such as resin zippers and coated pullers.
Q：What if the zipper bend out of shape during the dry cleaning?
A：Repeated dry cleaning or high temperature drying can cause a zipper to bend or deform when the zipper is not closed. Therefore, make sure the zipper is closed before washing, drying or dry-cleaning.
Q：Is rubber painted puller washable ?
A：The rubber painted puller is not washable, nor can it be guaranteed to bear ordinary washing.
Q：Where can I use the rope handle?
A：The rope handle is widely used. It can be used on the sliders of top fly zipper and pocket zipper, making zipper more convenient to pull up. It can also be used for zipper head of luggage in place of puller.
Q：How many kilograms can rope pull reach?
A：We judge from the size of the product and the depth of which the film is attached to the rope, the conventional pulling force of plastic TPU polyester rope is about 8KG, the conventional pulling force of plastic elastic rope is about 6KG, the conventional pulling force of plastic PVC rope is about 10KG, and the conventional pulling force of silicone rope is about 8KG. Our company has mature handle production technology, which can meet customers’ requirements of 15KG or above or special requirements.
Q：injection TPU handle, is the pulling force required for clothes and bags the same?
A：for clothing, pulling force is usually 8-10kg. Used for luggage, pulling force above 15KG is generally required.
Q：what are the differences between silicone products and PVC products? How?
A：the easiest and fastest way to tell is to use fire. Silica gel products will become white after fire, and the burning smell is small. After burning, the products will be white powder, while PVC products will turn black after fire, and the burning smell is bad.
Secondly, silica gel is soft and its feel good, while PVC products are relatively rough.
Finally, there are differences in the performance of high temperature resistance between the two. Silica gel can withstand high temperature of 350 degrees, while PVC will melt at this high temperature.
Q：how soft and hard can the plastic TPU rope handle be? What's the recommended temperature?
A：the softest hardness is 85 %. However, if the soft hardness is lower than 85%, the product yield is low and there are rough edges easily. Therefore, the soft hardness of TPU rope is recommended to be 95 %.
Q：is the handle of injection TPU rope environmentally friendly?
A：environmentally friendly, our TPU injection molding products have OEKO certificate.
Q：is the mold product exactly the same as the original sample?
A：the newly mold products of our company can be more than 95% similar to the original samples.
Q：can the rope handle be made into any shape?
A：this is not absolute. We will design the mold drawing according to the client’s drawing and confirm with the client.
Q：does the handle of injection TPU rope turn yellow easily?
A：transparent and white are prone to turn yellow, but our company adds anti-yellowing materials to our bulk goods. Products produced with soft and hard materials of 95% are normally sealed in transparent packaging bags. There will be no problem in storage for 6 months at room temperature. However, the transparent and white handles produced with soft 90 or 85% materials are more easily to yellowing.
Q：which colors are easier to absorb when touching the handle of plastic PVC rope?
A：there is A higher risk of color absorption when the handle of light-colored PVC rope is matched with dark-colored fabrics, especially those in bright red and navy blue.
Q：is there any way to use PVC handle and prevent cross color?
A：PVC products can be wrapped with paper or transparent film to isolate the products from the fabric.
Q：what is the fastness of the printed logo on the handle surface of the rope?
A：the logo or pattern printed on the surface ink of plastic products can achieve a clear and bright color effect, but the washing fastness not so good. The product only has one layer of printing surface, which is not scratch-resistant. After long-term use of friction, the printed logo or pattern will fall off.
Q：How much do you charge for molds? Can we receive a refund?
A：The mold fee of our company is charged according to different products, but the mold fee is always our company’s supporting service. As long as the customer orders reach a certain amount, we do not charge for mold fee. Or the annual cooperation amount reaches million, the mold fee can be fully refunded to you.
Q：at what ambient temperature can the brand of injection TPU be used?
A：it can be used at the ambient temperature from -30℃ to 50℃, but it is recommended not to use it for more than 8 hours if it exceeds this temperature range.
Q：can drip plastic PVC trademark withstand high temperature?
A：PVC will not change significantly at 10~35℃, but oil and yellowing may occur in high temperature environment, which is the limitation of materials and cannot be completely avoided at present.
Q：silicon eneca's products are prone to dust. How to deal with them?
A：anti-static materials can be added to the product, or anti-static treatment can be carried out on the surface of the product.
Q：can the trademark of drip plastic PVC be environmentally friendly?
A：PVC, also known as polyvinyl chloride, is A widely used industrial raw material. It is white and light yellow in a powdery state. Generally not uesd alone. Itself non-toxic (its vinyl chloride monomer and degradation of toxic), in the production of PVC products, need to add different additives, so the environmental protection level of PVC products is not the same. Our PVC drip plastic products have passed the environmental protection test of REACH 197.
Q：how much more expensive are silicone products than PVC products?
A：our company calculates the unit price according to the order quantity and process of specific products. Generally speaking, for products of the same size and process, silica gel material is about 50% more expensive than PVC material.
Q：why does the PVC trademark change to the fabric color?
A：there may be two reasons. One is that the color fastness of the fabric has not reached grade 4. The second is the poor quality of PVC raw materials. PVC material activity is very strong, especially when red and white color contrast, cross color is more obvious, at this time, it is suggested to do the thermal sublimation treatment, or change to silicone material.
Q：the color fastness of the fabric is over grade 4. How can the color be transferred to the PVC trademark?
A：the color fastness of the fabric is over grade 4, but there is still no guarantee that the color will not fade. It is suggested not to cut the fabric in a hurry after the fabric is dyed back. First, air dry and remove the oil in the well-ventilated place of the warehouse for 2-3 days, which can effectively reduce the problem of color shifting when the fabric comes into contact with the trademark.
Q：is there any way to solve the problem of cross color after sewing clothes with plastic PVC trademark?
A：as the PVC material is very active, it is difficult to clean it after dyeing. In this case, the customer is usually advised to change the trademark material to silica gel.
Q：drop plastic PVC trademark transparent color, only 3 months or so hair yellow is what reason?
A：the trademark you purchased may be made of poor materials. The transparent color drop plastic standard produced by our company will not turn yellow until more than one year at room temperature (avoid direct sunlight for A long time).
Q：is the color fastness the same for different thickness of microfiber?
A：the color fastness with a thickness of 0.65mm can reach grade 4-4.5, and grade 3-3.5 with A thickness of 1.4mm.
Q：why is the thickness of each product different with the trademark of drip plastic PVC?
A：since the drip plastic label is made by hand pouring liquid into the mold, it is difficult to achieve the same thickness for each product.
Q：what is the tearing fastness of the silicone trademark?
A：silica gel products have good environmental protection, stability, feel and surface treatment effect, so they are widely used. Silicone materials can be divided into ordinary materials and tear resistant materials. According to the process operation and product requirements, a certain ratio is generally carried out in the production process. The product thickness is generally not recommended to be less than 1MM, and the joint with the metal parts should be thicker to enhance the firmness and not easy to fracture.
Q：can the leather label guarantee the same color for each large goods?
A：if it is genuine leather, we can’t guarantee the same color even for the same batch of goods, because the raw materials can’t have one color for each skin. The word of leather mark is better correspondingly, same batch of goods can achieve same color, but cannot assure every batch of large goods is same color.
Q：may I ask your company how to match the bottom piece and the injection TPU sleeve loops?what material to use?
A：at present, There are two kinds of the bottom piece,injection TPU sleeve loops most commonly used: ordinary hairy surface and non-scratch.
The price of ordinary hairy surface is preferential, but the service life is short. After the TPU sleeve loops grasp for many times, the woolen surface will suffer from reduced grip and the fleeciness and messy of woolen surface.
The non-scratch wool service life is longer, can use about 10 thousand times catch close, in addition the non-scratch wool not easy to appear drop off, fluffy and disorderly and so on,so we recommend to use the non-scratch wool and project hookup match.
Q：how long is the service life of injection TPU integral sleeve loops?
A：normally, it lasts for 2 years. If properly preserved, it can last for 3 years. Corrosion may occur after aging.
Q：is the handle paint on the surface of plastic and metal functional parts firm?
A：hand paint is also called rubber paint. The product feels smooth and delicate. It is usually matte or semi-matte.It is not easy to fall off,but not resistant to corrosion,can be commonly washed.
Q：how about the color stability and washing fastness of resin buttons?
A：resin colored buttons are generally produced by matching colors and white color dyeing.
The resin buttons produced by matching colors are stable in color and washable. The resin buttons produced by dyeing, with a layer of color attached to the surface, are not washable. For garments requiring washing, the buttons should be fixed after finishing with water.
Q：how is the O clasp sewn on a garment or backpack?
A：there are two kinds of sewing techniques used most often: first, the fabric is punched first to expose the plastic from the hollow position of the fabric, and the other fabric with fabric edges are hidden below the edge of the fabric, and then sewing is carried out along the plastic edge of the O button.
The second method is to directly sew the O buckle and cloth belt in the required position.
Note: there is a narrow space for the fabric strips on both sides of O buckle. If sewing is normal, we suggest to use 1/2 sewing presser foot for sewing.
Q：what storage method do you need for your magnet products?
A：the magnetism of ndfeb magnet is greatly reduced by high temperature. When used for clothing bags, avoid using irons and other high temperature ironing equipment. Try to keep the magnet temperature in the appropriate temperature (-40℃ ~ 40℃).
When using or keeping the magnet, please avoid the environment containing corrosive gases, high conductivity (such as water containing electrolytes), acidic environment, organic solvents, etc. Otherwise, the corrosion of magnets and the weakening of magnetic properties and mechanical strength will be caused.
The magnet is hard and brittle, so it may break or fall off when used in occasions with vibration and impact. Therefore, the design should consider that even if the magnet breaks, it will not fall off.
Q：how is the transfer label ironed to the fabric? What is the temperature? How long and how much pressure?
A：Transfer label is based on the customer’s different fabrics to determine the product’s hot pressing temperature, time and pressure.
Q：What is the ideal way to use it?
A：The fewer time of pressing and molding, the better it is. It’s better to finish it once.Twice is also fine, but not three times. Assistive tools should be standardized, such as adding soft pads, and foaming silicone pads with appropriate hardness can be used for testing, after which hardness data can be measured and used as the standard. Try to avoid using soft cloth that cannot be quantified, and the softness of the cloth will decay in the process of pressing, so change it frequently to ensure the stability of quality.
Q：what is color transfer (sublimation)?
A：The dye molecules in the cloth are small and active (generally occurring in the field of chemical fiber fabrics), which can easily penetrate into the surface of the trademark in direct silk-screen printing or transfer printing, resulting in the change of trademark color. So the product should pass the test to add anti – sublimation bottom.
Q：what items are tested for transfer marks?
A：transferring standard clothes involves washing temperature, washing time, drying method, additive type, washing method, etc. so the aging, color transfer, elasticity, sweat stain, dry/wet friction and other items of products should be tested.
Q：What kind of drawings does the client need to provide?
A：non-warp AI or CDR documents for the factory to edit if necessary; PDF document for us to check whether the content is accurate and complete; When special fonts are used, they need to be packaged and sent to us.
