Recently, I met a few customers who came to Dad Kang to buy clothes and said, “Your clothes are not made of cotton.” I asked, “Why do you say that?” He said, “The feel is not good.” I asked, “What are you talking about?” What’s the comparison?” He said, “It doesn’t feel as good as the modal he bought. I want to buy the cotton one!” Well, I’m speechless. I admit that it doesn’t have the feel of your modal. . .
Today we will talk about the differences between the major fabrics. There are natural and synthetic ones. Among them is modal, which is a kind of rayon.
The four major natural fabrics are cotton, linen, wool and silk. Let’s talk about wool first. Wool underwear causes the same damage to the skin as aliphatic fiber, accounting for 17%. Therefore, although wool is expensive and has good warmth retention properties, it is not an ideal material for underwear.
Specifically, underwear materials can be divided into the following two types according to their material sources:
1. Natural materials:
Silk [SILK] protein fiber
Advantages: rich in luster and elasticity, with a unique “silky feeling”, and a sense of drape and elegance when worn on the body, noble Gorgeous; silk has good hygroscopicity, feels smooth and soft, and is more heat-resistant than cotton and wool; it has a soft touch, excellent material, no static electricity, good dyeing effect, pure color, sweat-absorbent, breathable, warm in winter and cool in summer characteristics.
Disadvantages: The wrinkle resistance of silk is worse than that of wool; the light resistance of silk is very poor, and it is not suitable to be exposed to the sun for a long time; silk, like wool, is a protein fiber and is particularly resistant to alkali; made of silk Clothes tend to absorb easily and are not strong enough; they will fade when exposed to light, water, alkali, high temperature, and mechanical friction, making them difficult to clean. They must be washed gently by hand or dry-cleaned.
Advantages: good moisture absorption and breathability, soft hand feel, warmth retention Strong, comfortable to wear; simple appearance and natural beauty, soft luster, good dyeing performance; particularly good alkali resistance and heat resistance.
Disadvantages: lack of elasticity and stiffness, easy to wrinkle; low color fastness, easy to fade; poor shape retention, easy to shrink and lose shape after washing (shrinkage rate is usually 4%~12% (left and right); especially afraid of acid. When concentrated sulfuric acid contaminates cotton, holes will be burned into the cotton. When acid (such as vinegar) accidentally gets on the clothes, it should be cleaned in time to prevent acetic acid from causing fatal damage to the clothes.
Here we will talk about combed cotton and pima cotton, which are often mentioned in underwear materials
Cotton) – A combing machine is used to remove the shorter fibers (less than about 1CM) from the cotton fibers, leaving longer and neat fibers. The yarn spun from combed cotton is of better quality. Fabrics made from combed cotton yarn have a high quality level in terms of texture, washability and durability.
Combed cotton refers to the addition of a delicate combing process during the spinning process. The method is to comb out shorter fibers and remove impurities in the cotton to create smooth yarn, making the cotton more resilient and difficult to break. Pilling, the quality of cotton will be more stable.
Combed cotton is actually a processing technology of ordinary cotton. It has obvious advantages over ordinary cotton and has good hygroscopicity. Smooth, comfortable to wear, easy to wash and dry, anti-odor, sweat-absorbent and moisture-wicking! Due to cost and workmanship, the price will be higher.
2. Because of its long growth period, long-staple cotton requires a lot of heat. Under the same heat conditions, the growth period of long-staple cotton is 10-15 days longer than that of upland cotton. Due to the weather and concentrated production areas, our long-staple cotton in Xinjiang has a fiber length of 38-39.7 mm. Compared with cotton from other domestic production areas, its color, length, foreign fibers and strength are the best
Cotton) is mainly grown in the United States, Peru and other places. It is an ultra-long fiber cotton among long-staple cotton fibers. The main body length is at least 35-46mm. On average, Pima cotton is about 35% longer than ordinary cotton. Pima cotton is just a subcategory of long-staple cotton. It is a type of long-staple cotton. Like Xinjiang long-staple cotton, it is an important raw material for making mercerized cotton. Pima cotton is actually a representative of the regional origin.
Advantages: breathable, unique cool feeling, no sweating Sticky to the body; bright color, good natural luster, not easy to fade, not easy to shrink; greater thermal conductivity and moisture absorption than cotton fabrics, not sensitive to acid and alkali reactions, anti-fungal, not prone to moisture and mildew; good resistance to moth and mildew.
Disadvantages: Rough feel, not smooth and comfortable to wear, easy to wrinkle, poor drape; hemp fiber is hard and has poor cohesion.
Linen-cotton blended fabric is the most suitable for summer underwear. Linen-cotton fabric absorbs sweat very well and has good breathability. People who are prone to sweating are most suitable to wear linen-cotton blended underwear.
2. Artificial materials:
Nylon (also called nylon) [NYLON or POLYAMIDE]p>
Tencel fabric (Tencel)
It has the same chemical composition as cotton yarn. Also known as LYOCELL viscose fiber, Tencel is its trade name in my country. Tencel is not silk, but a new viscose fiber produced using wood pulp as raw material and using solvent spinning technology. Tencel is lustrous, soft and elegant, and is less prone to deformation than other fabrics. In the production process, Tencel is non-toxic and pollution-free, so it is loved and sought after by contemporary people.
Bamboo fiber is a cellulose fiber extracted from naturally growing bamboo, following cotton, linen, wool, The fifth largest natural fiber after silk. Its essence is also a kind of viscose fiber [VISCOSE]. Bamboo fiber has good air permeability, instant water absorption, strong abrasion resistance and good dyeability. It has natural antibacterial, antibacterial, mite removal, deodorant and other properties. UV resistant.
In summary, it is best to choose natural fiber products for underwear. Among them, cotton products are more suitable because they have good hygroscopicity and warmth retention properties and are moderately priced. There are two types of synthetic fibers. One is a fabric made of viscose fiber and cotton blended from natural fibers. Since the raw materials are all natural materials, they not only have the excellent characteristics of cotton fiber, but also have their own advantages. They are also high-quality materials for making underwear. , the price will also be slightly higher. The other is fabric products made of chemical products. Generally, they have poor hygroscopicity, which is not conducive to the absorption and dispersion of human sweat. It is difficult to adjust the microclimate environment between the skin and underwear, so it is often stuffy when worn next to the body. Feel. It is worth noting that synthetic fiber underwear can also cause skin damage: the harm of nylon comes from the residual chemical substance – lactam, which can cause dryness, roughness, thickening of the skin, and even chapped, dermatitis, etc.
