What are the main material bags?2018-08-07 00:00:00
Luggage: It is a general term for all kinds of bags used to pack things, including general shopping bags, backpacks, shoulder bags, shoulder bags, purses, waistbags and a variety of suitcases and so on.
The common materials for making bags are:
1. PVC/PU leather
In our country, people are accustomed to using PVC resin as raw material for the production of artificial leather called PVC (referred to as artificial leather); PU resin as raw material for the production of artificial leather called PU leather (referred to as PU leather): PU resin and non-woven fabric as raw materials for the production of artificial leather called PU synthetic leather (referred to as synthetic leather).
The difference between PVC synthetic leather and PU synthetic leather can be distinguished by soaking in gasoline. The method is to use a small piece of fabric, put it in gasoline for half an hour, and then take it out. If it is PVC synthetic leather, it will become hard and brittle. If it is PU synthetic leather, it will not become hard and brittle.
Two, nylon / Oxford cloth
Oxford cloth is a new kind of fabric with various functions and wide uses. At present, there are mainly varieties of Oxford cloth in the market, such as sheath, full-elastic, nylon, Tiger and so on.
1, set Oxford cloth
It is specially used for making all kinds of bags. The warp and weft threads of the fabric are made of polyester FDY150D/36F. The plain weave is interwoven on a water jet loom. The density of warp and weft is 360/10cm-time210/10cm. The grey fabric has the advantages of light and thin texture, soft handle, good waterproof and durability after being treated with relaxation, alkali content, dyeing, anti-static and coating.
2, nylon Oxford cloth
Main production of flood control and rain protection supplies. The warp yarn is made of 200D nylon air texturing yarn, and the weft yarn is made of 160D nylon air change yarn. It is a plain weave structure, and its products are woven by water jet looms. After dyeing, finishing and coating, the grey fabric has the advantages of soft handle, strong drape, novel style and good waterproof performance, and the luster and sensory effect of nylon filament on the fabric mask. It is loved by users because of its fine quality and novel color. On the market, there are Tibetan blue, light black, tiger yellow, dark green and other different types of color, and according to customer demand batch selection of different colors.
3. Full play Oxford cloth.
Mainly produces bags. The fabric warp and weft yarns are all made of polyester DTY300D yarn, which is interwoven on a water-jet loom by choosing thick-point variable air permeable structure. After the fabric is slack scouring, predefined, alkali deweighting and softening, the reverse side of the fabric is further coated with rubber and plastic. Its texture is delicate, glossy and soft, waterproof, and the bags made with this product are fashionable and fashionable pets pursued by ladies.
4. Teague Oxford cloth
Mainly produces all kinds of bags. The warp is made of polyester DTY400D network yarn, and the weft yarn is made of polyester DTY silk 400D. Teague texture is used to interweave the water jet (loom) loom. Fabric design is novel, unique technology, highlighted front grille, strong three-dimensional sense, become the most prominent part of the fabric, but also in the reverse use of coating (PU) process, making it more waterproof, better drape, is the fashion of all kinds of bags.
5, weft Oxford cloth
Mainly produces all kinds of bags. The warp yarn is made of polyester FDY68D/24F, the weft yarn is made of FDY150D/36F, and the weaving process is made by interweaving the weft sliver on a water jet loom (with a dobby tap). The cloth bar is clear, which integrates modernity, art and drape. After dyeing and embossing, the gray fabric has the advantages of strong vertical sensibility and good waterproof.
For nylon materials, two proper terms, D and T, are first explained.
D - - Daniel = g / L * 9000 where G is the weight of the silk thread (g), L is the length of the silk thread (m), actually you don't need to remember any formula, it actually expresses the weight of the silk thread per unit length, for example, many knapsack bottom fabrics are made of DuPont 1000D nylon, it's very dense and wear well, then, in the back. Other parts of the package that are less likely to wear out can be made of 600D or 420D nylon, with a smaller relative density. The larger the number before D, the heavier the fabric of the same size. Normally the tent is made of 150D or 70D nylon, giving consideration to cost/weight/wear resistance, but in some high-grade super light-grade tents, such as MHW's Appurna, 30D, 40D fabrics are used to minimize weight at the cost of a substantial increase in costs and a reduction in relative wear resistance.
T - Fabric T, generally referred to as polyester taffeta, is a kind of nylon, silk-like fabric, generally used as tent outer tent and inner tent, light and strong, such as 190T, the front number of 1 inch (2.545CM) inside the warp and weft yarn number (density) and, in fact, is a density unit, you can also be simple It is believed that the larger the number before T, the heavier the fabric of the same area will be. For external accounts, in view of the vulnerability of the harsh environment, we should pay attention to whether the use of anti-scratch (ritop) structure, simply speaking, is a small square knitting, even if a point of damage, will not be more and more in the strong wind.
Knapsack materials are made of dense waterproof, wear-resistant, flame-retardant, tear-proof materials, multi-purpose artificial fiber (Kodra) and high-density Oxford nylon cloth (Hi-deity Nylon Oxford), generally used D to distinguish their functions, the higher the function, the better the more professional, some of its sewing lines have waterproof spray film treatment.
The main backpack materials are 420D Oxford nylon, 1000D nylon, 600D or 1000D polyester (polyester), or 1000D CORDVRA and other materials. 1000D material has high density and is very wearable. It is suitable for use in the field. CORDVRA is a famous high-end wear-resistant nylon roving fabric developed by DuPont Co. The wear resistance of the material is much higher than that of nylon or polyester, and it is light in weight. More than 90% of the world's famous brands.
