Question 2: Does 7 kg of French velvet belong to the high gram weight? The gram weight is based on the weight per square meter. How many square meters is your 7 kg? It doesn't have to be Gao Kezhong.
question 3: how is the high density and high weight knitted fabric made? First of all, let's look at what determines the gram weight of knitted fabrics. For fabrics with the same area, if the same yarn count is used, then its grammage is determined by the thickness and the under-filling coefficient (which refers to the gap between yarns). Knowing this, we can solve it. First of all, to reduce the gap between yarns, the finer the yarn, the better. Also, the higher the machine number of the knitting machine, the better. Secondly, the higher the shrinkage rate of this yarn when dyeing, the better. Thirdly, it is better to add spandex, because it can make the fabric shrink more tightly. Fourth, increase the thickness of the fabric. Double-sided fabric will be thicker than single-sided fabric in theory, and then, through weave design, as many yarns as possible can be used in unit area.
Question 4: What does the high grammage of cartons mean? It should be high grammage, indicating the quality of paper.
Question 5: Why is the grammage of double-sided adhesive paper divided into high grammage? What is its use? Quantities: 5,6,7,8,9,1,12 grams, 15,18,2,3 grams.
flat paper (flat Justin Cheung specification: positive degree 787 ×l92; Generosity 85×1168 mm, etc.
web specifications: 787mm, 192mm, 85mm, etc.
dongguan fubang paper co., ltd. is an enterprise mainly producing environmentally-friendly double-sided adhesive paper, copy paper, print paper and carbonless paper.
question 6: does the higher the number of stitches, the lower the gram weight, or is it higher? Generally speaking, the lower the gram weight.
the higher the number of stitches, the thinner the yarn used and the higher the density. As you can imagine, the flat knitting machine has a large machine number, but the fabric it weaves is very thick. But it is not absolute, and it is also related to density, yarn collocation, weave and machine type.
question 7: how to calculate the weight of a piece of paper? Now we know the length, width and height of a piece of paper, and there are gram values in the specifications of gram paper, which reflect the thickness of the paper, generally 7g and 8g, which refer to the weight of 1 square meter of paper.
paper area × specification grams = paper weight.
paper area = length × width, m is the unit, and the specification gram unit is gram/square meter.
the unit of weight of paper is grams.
question 8: what are the common grams of double-sided adhesive paper? What are their uses? Double offset paper refers to printing paper, also called offset paper. Divided into low gram weight and high gram weight. Common grams of low gram weight are: 5g, 6g, 7g, 8g, 9g, 1g, 12g；; The common grams of high gram weight are: 15g, 18g, 2g, 3g
6g double-sided adhesive paper, which is regarded as the best choice by many magazines, publishing houses, printing houses and processing plants.
7g double-coated paper: It has an ideal cost performance and is widely used in high-end books, textbooks, teaching materials and counseling materials. Applicable printing methods: rotary printing and plain printing.
8g offset paper: it is the most widely used high-grade offset paper in many publishing houses and paper processing plants.
High-weight double-sided adhesive tape uses: printing and making posters, high-end product catalogs, clothing color trademarks, conference invitations, birthday cards, handicrafts, packaging products, etc. Check the paper passer-by network.
question 9: what are the grams of double-sided adhesive paper? 5, 6, 7, 8, 9, 1, 12 grams, 15, 18, 2, 3 grams. More than 12 grams is usually high-gram double-sided adhesive paper. Widely used: calendars, calendars, packaging, picture books, etc., more can see the paper passerby network.
