(six) cotton: 7D, 6D, 15D, A, B and C. We usually use 7D/ class A, 6D less. Low grade products or strongholds are very full and hard products are 15D/B or C grade. 7D is very flexible and flexible, and 15D is hard and hard.
According to the length of the fiber, it is also 64MM and 32MM cotton. The former is used for cotton washing by hand, while the latter is used for cotton punching.
The general practice is to enter the raw cotton to make their own loose cotton, to ensure that the loose cotton workers operate correctly and have enough times of loosening cotton, so that the cotton can be released completely and achieve good elasticity. If the loose cotton effect is not good, the amount of cotton will cause a lot of waste.
(seven) colloidal particles: (PP, PE), the diameter should be greater than or equal to 3MM, and the particles are smooth and even. Products exported to Europe are usually PE more environmentally friendly and exported to the United States, except for special requests from customers. PP or PE can be used and PP is cheaper. All the export products must be wrapped in an inner bag unless the guests specify.
(eight) plastic accessories: existing plastic accessories, the body can not be changed, such as size, size, shape, etc., otherwise the need to open the mold, the general cost of plastic molds is expensive, thousands of yuan to tens of thousands of yuan, depending on the size of the mould, the difficulty of the process, the selection of mould materials, so the production order is less than three hundred thousand. We all have to pay another mold fee.
(nine) (color) printed matter: including color box, hanging card, sticker and so on, the price of color printing is directly related to the number of orders. If the order is small, the number of printed paper is small, the color difference is large, the color is uneven, the proportion of the manufacturer's loss increases, so the unit price must be high.
