传统的天然纤维包括棉、麻、丝和羊毛。随着科学技术的发展，新的天然纤维也在不断出现，如现在广泛使用的菠萝叶纤维和竹纤维。都是大自然奉献给我们的纺织纤维原料。棉、麻、竹、菠萝叶纤维是天然的纤维素纤维，被火点燃后迅速碳化成灰烬，并伴有烧草的气味。头、丝纤维是天然的动物纤维，点燃后会变焦，有烧焦头发的气味。

Traditional natural fibers include cotton, linen, silk, and wool. With the development of science and technology, new natural fibers are constantly emerging, such as the widely used pineapple leaf fibers and bamboo fibers. They are all high-quality textile fiber materials that nature has dedicated to us. Cotton, hemp, bamboo, and pineapple leaf fibers are natural cellulose fibers that quickly carbonize into ashes after being ignited by fire, accompanied by the smell of burning grass. Head and silk fibers are natural animal fibers that will become charred upon ignition, giving off a burnt hair odor.

人类使用天然纤维的历史可以追溯到古代。根据科技史，我国丝绸和亚麻织物出现在4000-5000年前，羊毛织物出现在3000年前，棉织物出现在2000年前。

The history of human use of natural fibers can be traced back to ancient times. According to the history of Chinese science and technology, silk and linen fabrics appeared in China 4000 to 5000 years ago, wool fabrics appeared 3000 years ago, and cotton fabrics appeared 2000 years ago.

植物纤维：

Plant fiber:

主要成分是纤维素，又称天然纤维素纤维。从植物的种子、果实、茎和叶中获得的纤维。根据生长在植物上的部位不同，可分为种子纤维、叶纤维和茎纤维。

The main component is cellulose, also known as natural cellulose fibers. Fiber obtained from the seeds, fruits, stems, and leaves of plants. According to the different parts of the plant that grow, it can be divided into seed fibers, leaf fibers, and stem fibers.

1.种子纤维：棉、木棉等。

1. Seed fibers: cotton, kapok, etc.

2.叶纤维：剑麻、蕉麻等。

2. Leaf fibers: sisal, banana, etc.

3.茎纤维：苎麻、亚麻、大麻、黄麻等。

3. Stem fibers: ramie, flax, hemp, jute, etc.

动物纤维：

Animal fiber:

主要成分是蛋白质，又称天然蛋白质纤维，分为毛和腺分泌物两类。

The main component is protein, also known as natural protein fibers, which are divided into two categories: hair and glandular secretions.

1.毛类：绵羊毛、山羊毛、骆驼毛、兔毛、牦牛毛等。

1. Hair types: sheep hair, goat hair, camel hair, rabbit hair, yak hair, etc.

2.腺体分泌：桑蚕丝、柞蚕丝等。

2. Gland secretion: mulberry silk, oak silk, etc.

1.天然纤维具有吸湿性好、透气性好的优点。

1. Natural fibers have the advantages of good moisture absorption and breathability.

由于天然纤维，尤其是棉和丝的结构比较多，而针织品的针圈结构一般也比较松散，针脚之间的缝隙比较大，尤其是夏季运动衫、背心和袜子所用的纱线比较细，人体排出的汗液可以随时被吸收散发，很难附着在人体上。所以，穿棉毛衣物紧贴皮肤，感觉透气舒适。

Due to the abundant structure of natural fibers, especially cotton and silk, and the loose needle loop structure of knitted goods, the gaps between the stitches are relatively large, especially the fine yarn used in summer sportswear, vests, and socks. Sweat excreted by the human body can be absorbed and emitted at any time, making it difficult to adhere to the human body. So, wearing cotton and wool clothing that fits snugly against the skin feels breathable and comfortable.

2.天然纤维还具有弹性足、延伸性好等优点。

2. Natural fibers also have advantages such as sufficient elasticity and good extensibility.

天然纤维中的羊毛具有良好的弹性和延展性，使得毛衣、裤子等羊毛制成的针织品穿着更加舒适，不易起皱变形。针织内衣、袜子和手套具有良好的弹性和延展性。它们可以自由伸展，轻松穿脱，能够适应人体各部位的体型和儿童活动时拉伸弯曲的要求。

Wool in natural fibers has good elasticity and stretchability, making knitwear made of wool such as sweaters and pants more comfortable to wear and less prone to wrinkling and deformation. Knitted underwear, socks, and gloves have good elasticity and stretchability. They can stretch freely, easily put on and take off, and can adapt to the body shape of various parts of the human body and the requirements of children's stretching and bending during activities.

1.缺乏弹性且不挺括，容易起皱。

1. Lack of elasticity and stiffness, prone to wrinkling.

2.色牢度不高，容易褪色。

2. Low color fastness and easy fading.

3.天然纤维往往保形性差，洗涤后容易收缩变形(收缩率通常在4%-12%左右)。

3. Natural fibers often have poor shape retention and are prone to shrinkage and deformation after washing (the shrinkage rate is usually around 4% -12%).
