Cotton cloth became the main clothing material for the vast majority of people in our country

It began in the Ming Dynasty. In his Travels in Suleiman, the 9th-century Arab traveler Suleiman wrote that cotton was seen in China and was seen as a "flower" in the garden. "The Book of Liang: The Biography of Gaochang" records:

There is "grass, solid like a cocoon, and the silk in the cocoon is like a fine silk, and it is called white stacks." Cotton.

At present, the earliest cotton textile relics seen in the Central Plains are a cotton blanket found in an ancient tomb of the Southern Song Dynasty. In the early years of the Yuan Dynasty, the imperial court took cotton cloth as the first of the summer taxes (cloth, silk, silk, cotton), set up a kapok lifting department, and collected cotton cloth from the people, according to records, as many as 100,000 horses per year, it can be seen that cotton cloth has become the main textile clothing. The Ming Dynasty also expropriated cotton cloth, published books on cotton planting technology, and persuaded the people to plant cotton.

From the Ming Dynasty Song Yingxing's "Tiangong Kaiwu" recorded that "cotton cloth is available in every inch of land" and "there must be ten rooms of looms", it can be seen that cotton planting and cotton weaving have spread all over the country at that time. At the end of the Qing Dynasty, China successively introduced improved varieties of upland cotton from the United States, replacing African cotton and Asian cotton with poor quality and low yield. At present, all the upland cotton grown in China is upland cotton and its variants.

Summary. The standard pure cotton material is a natural polymer compound, but nowadays many of them are blended fabrics, that is, polyester (organic compound) is added to it.

45+ cotton cloth is a synthetic fiber. ()a.Right +bWrong.

The standard pure cotton material is a natural polymer compound, but nowadays many of them are blended fabrics, that is, polyester (organic compound) is added to it.

It is a hail structure formed by protrusions of epidermal tissue.

Cotton fibroblasts are derived from ovule beads by a single cell, and are the model single cells with the fastest elongation and the most synthetic cellulose among higher plants. The remaining stages of differentiation and development can be divided into four stages: fibroblast differentiation and protrusion, rapid elongation of fibroblasts, synthesis and dehydration of secondary walls, which are complex processes of co-expression and regulation of multiple genes.

In the garment production industry, cotton fabrics are widely used, and the clothes made of cotton fabrics have good moisture absorption, warmth and corrosion resistance, and the heat resistance of cotton fabrics is also good, so cotton fabric clothes are comfortable to wear, and parents also like to buy cotton fabric clothes for infants and young children, so how many kinds of cotton fabrics are there, and what kinds of cotton fabrics are there?

Cotton fabrics can actually be divided into hundreds, because there are many factors that determine the type of fabric, in addition to raw materials, there are weaving textures, yarn thickness, warp and weft density, printing and dyeing processes, etc., if these factors are combined, theoretically it is infinite, so there are many cotton fabrics.

Here are a few types of cotton fabrics that are often in contact with:

1. Flannel. Flannel refers to the cotton fabric with fluffy fluff on the surface after brushing, which has a strong three-dimensional effect, high gloss, and is very soft and thick to the touch. However, according to the different characteristics, it is also divided into different flannel, according to the fabric structure, it can be divided into plain cloth velvet, serge velvet, twill velvet, and according to the printing and dyeing processing method, it can be divided into bleached velvet, variegated velvet, printed velvet and yarn-dyed velvet.

2. Corduroy.

The main raw material of corduroy is also cotton-based, which is a cotton fabric that cuts the weft and forms a longitudinal velvet strip on the surface. According to the difference of the materials used, it can be divided into full-yarn corduroy, half-line corduroy and full-line corduroy, which has the characteristics of good warmth, wear-resistance and wear-resistance.

3. Velveteen. Velveteen, also known as mercerized velveteen, is mainly a pure cotton fabric woven with fleece weaving, which can be divided into warp fleece and weft fleece according to different processing methods, with a soft feel, warmth is also very good, and it is also very durable.

Cotton fabric can be divided into three kinds of fabrics according to the different fabric structures, mainly plain fabrics, twill fabrics, and satin fabrics.

First of all, the plain weave fabric is characterized by the fact that the surface of the cloth is very smooth, and its weft and warp yarns must be interwoven once every other yarn, this warp and weft yarn has thickness and fineness, according to its thickness can also be divided into fine flat cloth, medium flat cloth and coarse flat cloth.

Twill fabric is interwoven with two warp yarns and one weft yarn, or three warp yarns and one weft yarn intertwined, at a 45-degree angle when intertwined, usually twill fabric is thicker than plain weave fabric.

The raw materials of satin cloth are mainly cotton and some silk fabrics, which are different from the interweaving methods of the previous two, and the warp and weft yarns are evenly distributed on the fabric surface separately.

According to the different colors of the fabric, cotton fabrics can be divided into plain fabrics, printed fabrics, bleached fabrics and dyed fabrics.

First of all, plain fabric is a cloth dyed with only one single color, and this kind of fabric has no pattern.

Printed fabric is a cloth that has been printed and processed, generally the front color and pattern of this printed fabric are bright and eye-catching, but the reverse pattern is not called blurry and dull.

Bleached fabric is the fabric obtained after the original fabric has been bleached.

The first dyed fabric is also called yarn-dyed fabric. This cloth is generally blue to the finished cloth, and it is made by dyeing the cotton yarn before weaving.

The advantages of general cotton cloth are that the surface gloss of the cloth is high, the feel is soft, and it has good air permeability and moisture absorption; The disadvantage of pure cotton cloth is that it is not very smooth to the touch, and this fabric is easy to wrinkle, and it is not easy to recover.

The above is about the classification of cotton fabrics and its characteristics.

The cotton textile industry emerged in the late Southern Song Dynasty; In the Yuan Dynasty, the cotton textile industry was developed, and cotton cloth became the main clothing material for people in the south of the Yangtze River; The ecliptic of the Yuan Dynasty.

Po popularized the advanced cotton textile technology of the Li nationality; Songjiang was the center of the cotton textile industry in the Yuan and Ming dynasties; In the Ming Dynasty, cotton cloth was produced a lot and the texture was excellent, and people's clothing was mainly cotton cloth.

The cotton textile industry was developed in the Yuan Dynasty, and cotton cloth became the main clothing choice for people in the south of the Yangtze River

The old textbook is said to be the Ming Dynasty, and the new textbook is advanced to the Southern Song Dynasty.

Sorry, wrong, it's d

Answer] Beitan shed: letter grip plain weave.

Analysis: Plain weave weave, the thinnest fabric in cotton fabrics, has clear cloth holes, good air permeability, and has the style characteristics of "thin, thin and cool".

Answer C This question tests the knowledge of agriculture in the Ming Dynasty, focusing on the candidate's ability to combine historical things with historical time to solve problems correctly. It can be seen from the textbooks of the Recall Bureau that there were cotton blankets in the Southern Song Dynasty, quilts in the Yuan Dynasty, and cotton cloth drafts in the Song and Yuan dynasties, but as the main clothing raw materials for the majority of the people, they have not yet been formed, because the planting area is not large and the output is limited; During the Ming Dynasty, Taizu encouraged cotton planting and promoted cotton planting, and cotton planting spread all over the north and south.

Cotton gradually became the main clothing of the people. So the correct answer is c.
