Four-piece wool cloth:
To put it bluntly, it is chemical fiber. The price of the four-piece fabric with the lowest quality is generally around 50 yuan. The color fades seriously. It can't be used after washing it for a few times. The price of this kind of goods is about 20-30. There are also bold ones. The seller is shoddy, the buyer has to open their eyes and identify carefully.
Four-piece polyester cotton suit:
Products generally use polyester-cotton fabrics with a ratio of 65% polyester and 35% cotton. Polyester-cotton is divided into two types: plain weave and twill weave. We will not introduce more, because there is less and less comfortable using cotton.
Four-piece cotton suit:
The cloth of pure cotton texture is soft, comfortable, not easy to generate static electricity, good hygroscopicity, sweat absorption and softness, which is conducive to the "breathing" of sweat glands and physical health, and is soft to the touch, which is very easy to create a sleeping atmosphere. All cotton fabrics have the problem of shrinkage and fading, and general home textile fabrics have undergone pre-shrinking treatment. However, after pre-shrinking treatment does not mean no shrinkage, but means that the shrinkage rate is controlled within 3%-4%% of the national standard, so that such products can be purchased with confidence.
According to the printing and dyeing process:
It is divided into four sets of ordinary printing and dyeing, semi-reactive four-piece sets, and reactive four-piece sets. Reactive printing and dyeing is of course better than ordinary printing and dyeing. Reactive printing and dyeing is in the process of dyeing and printing. Form a whole with fiber. The fabric has excellent dust resistance, high cleanliness, high color fastness, and of course the cost is much higher than that of pigment printing and dyeing. Compared with pigment printing, reactive printing has many advantages, such as good air permeability, excellent fastness, and soft hand feeling, but there are also problems such as cumbersome printing process, long process and difficult processing.

According to the textile process:
It is divided into plain weave, twill weave, sanding, satin, printing, embroidery, and jacquard. The process is becoming more and more complicated. Of course, the fabric is getting softer and softer, and the relative price is getting higher and higher! Two or four sets of process parameters and Features
Choose different fabrics:
Will produce different effects. Plain weave fabrics are rougher and warmer, using a longitudinally interlaced weave. Compared with other fabrics, it feels rougher, but very strong. Different yarn counts have different feel. The higher the yarn count, the better the hand feel and the higher the comfort. The weave of the twill fabric has an obvious slope and a little luster. When the yarn density is the same, the hand feel and comfort are higher than the plain weave. Satin is a new fabric, very flat, shiny, looks like satin, rich and luxurious, more comfortable, but its durability is slightly worse than that of twill.
The real quality of the fabric first lies in its density:
That is the usual count and yarn count. Because the higher the density of the cloth, the better the cotton quality is required, the softer the hand, the more shiny, and the higher the production process requirements, so whether it is pure cotton or polyester cotton, the higher the density, the better the fabric quality .
Fabric count:
That is what we often see 30, 40, 60, etc.! The count is the standard for yarn thickness. For example, one or two cotton can be made into 30 yarns of 1 meter, that is 30 yarns, and one or two cotton can be made into 40 yarns of 1 meter long, that is 40 yarns; 1 two cottons can be made into 60 yarns. A yarn with a length of 1 meter is 60 yarns. In fact, the higher the yarn count, the thinner the yarn. The thinner the yarn is to weave, the softer and more comfortable the cloth is. However, high-count fabrics require high-quality raw materials (cotton), and they also have high requirements for spinning mills and weaving mills, so the cost of fabrics is relatively high.
Is the higher the count, the better? Of course the count is a key indicator for evaluating the quality of bedding, but it is not absolute! In fact, the higher the count, the finer the yarn. Use this kind of yarn The thinner the weave, the softer and more comfortable the cloth is. For example, many bedding sellers say that their fabrics are 120 pieces, and buyers should be careful. For bedding, 80 pieces are very rare, let alone 120 pieces, because 120 pieces are very thin. Thin fabrics may not be suitable for bedding products at all. At this time, beware of the seller's suspicion of stealing the concept. Maybe he is talking about the warp and weft density instead of the count!
Fabric density:
The warp and weft density refers to the number of warp and weft yarns arranged per square inch. For example, the commonly seen "40×40/128×68" means that the warp and weft are 40 respectively. The warp and weft density is 128×68, which is also bedding An important technical indicator for purchase, because the choice of fabric count is very small, nothing more than 30, 40, 60, so the most important thing for bed quality under the premise of the same count is to look at the density, the more the density The taller the better! But it is important to remember that high-density can be achieved with high-density. It would be ridiculous if only 20 densities are known as high-density.

Woolen fabric is a general term for fabrics woven from various types of wool and cashmere. It is usually used to make formal and high-end clothing such as dresses, suits, and overcoats. Its advantages are anti-wrinkle and abrasion resistance, soft hand feeling, elegant and crisp, full of elasticity and strong warmth retention. Its main disadvantage is that it is difficult to wash and is not suitable for making summer clothes.

Woolen coats made of good woolen fabrics are soft and clean, with a smooth and oily feel, and can also be divided into many types: for example: pure woolen woolen cloth and chemical fiber woolen cloth, there is a clear difference in appearance: pure wool color and luster Soft and shiny, chemical fiber has a darker luster; pure wool has a soft touch, while chemical fiber is stiff and not soft; pure wool has good elasticity and good recovery, while chemical fiber has obvious creases after grasping and relaxing.

The meaning of polyester is polyester. Polyester fiber is an important variety of synthetic fibers, and it is the trade name of polyester fiber in my country. Fiber made by spinning and post-processing.

The advantages are:

1. high strength. The short fiber strength is 2.6～5.7cN/dtex, and the high tenacity fiber is 5.6～8.0cN/dtex. Due to its low hygroscopicity, its wet strength and dry strength are basically the same.

2. Good flexibility. The elasticity is close to that of wool, and it can almost completely recover when it stretches 5% to 6%. The wrinkle resistance exceeds other fibers, that is, the fabric does not wrinkle and has good dimensional stability.

3. Heat-resistant polyester is made by melt spinning, and the formed fiber can be heated and melted again, which is a thermoplastic fiber. The melting point of polyester is relatively high.

4. Good thermoplasticity and poor melting resistance. Because polyester has a smooth surface and tightly arranged internal molecules, polyester is the most heat-resistant fabric among synthetic fabrics. It is thermoplastic and can be made into pleated skirts with long-lasting pleats.

5. Good abrasion resistance. The abrasion resistance is second only to nylon, which is the best in abrasion resistance, and is better than other natural fibers and synthetic fibers.

6. Good light resistance. Lightfastness is second only to acrylic fiber. The light fastness of polyester fabric is better, except that it is worse than acrylic, its light fastness is better than natural fiber fabric. Especially the light fastness behind the glass is very good, almost as good as acrylic.

7. preservative. It is resistant to bleaching agents, oxidants, hydrocarbons, ketones, petroleum products and inorganic acids. It is resistant to dilute alkali, not afraid of mildew, but hot alkali can make it decompose. It also has strong resistance to acid and alkali, and UV resistance

The disadvantages are:

1 Poor dyeability, but good color fastness, not easy to fade. Because there is no specific dyeing group on the molecular chain of polyester, and the polarity is small, it is difficult to dye, the dyeability is poor, and the dye molecules are not easy to enter the fiber.

2. Poor hygroscopicity, sultry feeling when wearing, and easy to be charged with static electricity and dirt, which affects appearance and comfort. However, it is very easy to dry after washing, and the wet strength hardly drops, does not deform, and has good wash and wear properties.

Modacrylic is a modified polyacrylonitrile fiber.
Modacrylic fibre modacrylic fibre is also known as modified polyacrylonitrile fibre. Synthetic fiber made of linear polymer copolymer containing 35% to 85% of acrylonitrile monomer. The American Union Carbide Company began industrial production in 1948 under the trade name Dynel.

There are two main types of modified polyacrylonitrile fibers that are industrially produced recently: fibers made from copolymers of acrylonitrile and vinyl chloride; fibers made from copolymers of acrylonitrile and vinylidene chloride, namely, polyacrylonitrile fiber. These two types of modified polyacrylonitrile fibers are sometimes collectively referred to as acrylonitrile fibers, which have good flame resistance.

Synthetic fiber classification:

1. Classified by structure:

1. Carbon chain synthetic fibers, such as polypropylene fiber (polypropylene fiber), polyacrylonitrile fiber (acrylic fiber), polyvinyl formal fiber (vinylon).

2. Hetero-chain synthetic fibers, such as polyamide fiber (nylon), polyethylene terephthalate (polyester), etc.

2. Classified by function:

1. High-temperature resistant fiber, such as polybendazole fiber

2. High temperature corrosion resistant fiber, such as polytetrafluoroethylene.

3. High-strength fibers, such as poly-p-phenylene terephthalamide.

4. Radiation resistant fiber, such as polyimide fiber.

5. In addition, there are flame retardant fibers, polymer optical fibers, etc.

1. The difference between leather

(1) Touch by hand: touch the surface of the leather with your hand. If it feels smooth, soft, plump, and elastic, it is real leather; the surface of artificial synthetic leather is astringent, rigid, and has poor flexibility.

(2) Seeing: The real leather has clear hairs and patterns, yellow cowhide has relatively well-proportioned fine pores, yak cowhide has coarser and sparse pores, and goat skin has scaly pores.

(3) Smell: All leather has the smell of leather; and artificial leather has a strong irritating plastic smell.

(4) Ignite: tear off a little fiber from the back of real leather and artificial leather. After lighting, it emits a pungent odor. The lumps are the artificial leather; the hair odor and the lumps are not formed by the leather.

How to care for and maintain leather bags?
1. It cannot be irradiated under strong light or placed in strong acid.
2. Wipe dry when exposed to rain and put it in a ventilated place to dry.
3. After the leather bag becomes moldy, wipe it dry with a soft cloth, and then apply care agents such as Bi Lizhu.
4. When there are ballpoint pen marks on it, milk can be used to clean it.
