2. Hemp fabric (1) Characteristics of hemp fabric
Hemp fabric refers to hemp fiber (including ramie and linen) pure textile fabrics and their blended or interwoven fabrics. It has the following characteristics:
1. Hemp fiber is a cellulose fiber, and its fabric has similar properties to cotton.
2. Hemp fabric has the characteristics of high strength, good hygroscopicity and strong thermal conductivity, especially the strength is the first among natural fibers.
3. The sackcloth has good dyeing performance, bright color and is not easy to fade.
4. It is not very sensitive to alkali and acid, and mercerization can occur in caustic soda to enhance the strength and gloss; after a short period of time (1 to 2 minutes) in dilute acid, it basically does not change. Of course, the strong acid still hurts it.
5. Good mold resistance, not easy to be damp and moldy.
(2) Variety of hemp fabrics
The varieties of hemp fabrics are much less than cotton and woolen fabrics, but because of their unique rugged style and cool moisture permeability, coupled with the return to nature in recent years, their varieties are becoming more and more abundant.
1. Pure linen fabric
â‘´ Ramie fabric Ramie fabric is a fabric woven from ramie fiber, which is divided into two types: hand-made and woven. Handmade ramie cloth is commonly known as summer cloth. Because of its uneven quality, it is often used as mosquito nets, linen lining, and lining cloth materials; while the quality and appearance of woven ramie cloth are better than that of handmade summer cloth. After bleaching or dyeing, all kinds of clothing can be made. Ramie clothing is very cool, breathable and sweaty, which is an ideal summer fabric.
⑵ Linen fabric Linen fabric is made of flax fiber, which is divided into primary color and bleaching. The original color linen is not bleached and dyed, and has the natural color of linen fiber. Bleached linen is bleached and mercerized. It is softer, smoother, whiter and more elastic than the original color cloth. Linen fabrics become fabrics for various summer clothing, such as outerwear, shirts, curtains, sand releases, etc. due to the advantages of fine and smooth cloth surface, soft and elastic feel, cool and comfortable to wear, and no sweating.
⑶ Other hemp fabrics In addition to ramie and linen, there are many other hemp fabrics, such as jute, sisal, abaca, etc. These hemp fabrics are rarely used in clothing, mostly used in packaging bags, fishing boat ropes, etc. In addition, apocynum venetum clothing, which has been very popular in recent years, is increasingly recognized and accepted as a health apparel.
2. Hemp blended and interwoven fabrics
Ramie and flax fibers can be blended or interwoven with other fibers, most of which are low proportion hemp fibers blended or interwoven with chemical fibers and natural fibers. The purpose is to gather the length of various types of fibers and make up for their shortcomings, so that the fabric performance is more excellent. Can reduce the cost price, welcomed by consumers.
(1) Hemp-cotton blended interwoven fabrics Hemp-cotton blended fabrics are generally blended with 55% hemp and 45% cotton or 50% each of hemp and cotton. The appearance maintains the unique rugged and crisp style of hemp fabric, and has the soft characteristics of cotton fabric, which improves the shortcomings of hemp fabric which is not clean enough and easy to fluff. Cotton and linen interwoven fabrics are mostly interwoven fabrics made of cotton warp and hemp. The texture is firm and smooth, and the texture is softer than pure linen. Hemp-cotton blended interwoven fabrics are mostly thin and light, suitable for summer clothing.
⑵ Wool and linen blended fabrics Various fabrics woven with yarns of different wool and linen blending ratios, including wool and linen herringbone and various wool and linen. Wool and linen blended fabric has the characteristics of smooth, crisp and good elasticity, suitable for making young men and women clothing, suits, skirts, waistcoats, etc.
(3) Silk and linen blended fabric Silk and linen sand-washed fabric is a new product developed by sand-washing process in recent years. It combines the excellent characteristics of silk fabrics and hemp fabrics, and at the same time overcomes the weakness of silk sand-washed fabrics, resulting in a cool and elastic feel. This fabric is suitable for making summer clothing.
â‘· Hemp and chemical fiber blended fabrics include fabrics blended with hemp and one chemical fiber, and fabrics blended with hemp and two or more chemical fibers. Such as: polyester, linen, sticky linen and other fabrics, "three in one" fabrics.
a. Polyester / ramie cloth: refers to a fabric made of polyester and hemp fiber blended yarn, or a warp and weft yarn using a polyester and linen blended fabric. Including polyester and linen tweed, polyester and linen yarn-dyed fabric, linen and polyester canvas and polyester and linen fine spinning, polyester and linen golf wool and other varieties. Polyester and linen have both polyester and hemp fiber properties, they are crisp and breathable, and have a strong sense of wool. Suitable for making suits, fashion, skirts, jackets, etc.
b. "Three-in-one" blended fabric: refers to a fabric blended with hemp and two fibers, such as polyester wool, polyester cotton, polyester nitrile, etc. This kind of fabric has the characteristics of coolness, comfort, stiffness and breathability of hemp fabric, as well as the excellent characteristics of the other two fibers. The characteristics of washing and no-iron can meet the needs of various uses. It is very suitable for making all kinds of men's and women's fashion, jackets, skirts, pants, etc.

3. Silk fabric (1) Features of silk fabric
Silk fabrics mainly refer to pure or blended and interwoven textiles woven with silk as raw materials. Because of its unique and excellent wearability, it has been widely used. Its main features are as follows:
1. Silk fabrics have good strength and elasticity, but poor wrinkle resistance.
2. Silk fabrics have good hygroscopicity, dyeing and luster, and the dyed fabrics are colorful and bright. Its water content can reach 11 ~ 12%.
3. Silk fabrics are acid and alkali resistant. It has certain stability to inorganic acid (concentrated inorganic acid can hydrolyze silk), sensitive to alkali reaction, but more stable than wool.
