1. Cotton: Cotton fiber is the fiber covered on cotton seeds, referred to as cotton. The cotton fiber from which the cottonseed is removed is called lint or raw cotton.

Variety: According to the thickness, length and strength of the fiber, raw cotton can generally be divided into three categories: long-staple cotton, fine-staple cotton and coarse cotton.

Structure: Cotton fiber is a tubular body with one end open, which shrinks into a hollow ribbon after maturity and drying. The main component of the cotton fiber wall is cellulose with a high degree of polymerization. In the dried mature cotton fiber, the content of cellulose is more than 95%, which is a highly pure cellulose resource in nature.

Performance: cotton fiber is generally thin and soft, the skin feels more comfortable. It has a strong moisture absorption capacity. In general, cotton fibers are stronger wet than dry. The elasticity is poor, and the cellulose can be used as anti-wrinkle finishing to make it have better shape retention. Cotton fiber has better warmth retention. At high temperature, the plasticity is better. Cotton fiber such as long time contact with the sun, the strength is reduced, the fiber will be hard and brittle: in case of oxidizing agents, bleaching powder or dyes with oxidation properties, the fiber strength will also be reduced, and brittle and hard.

2. Recognition of front and back of fabric

1) According to the weave recognition of the fabric: the common weave has three kinds of plain weave, twill weave and satin weave. The front and back of plain weave fabrics are not much different in appearance, so there is often no positive and negative points; twill fabrics can be divided into yarn fabrics and thread fabrics. The square grain of the twill of the yarn fabric is clear, and the surface grain of the fabric is the front. The front and back lines of the thread fabric are more obvious, and the front line is a prime; Satin fabric is divided into warp satin and weft satin. The front warp of warp satin emerges more, the front weft of weft satin emerges more, the front of satin fabric is relatively smooth and glossy, the back weave is not obvious, and the luster is relatively dull.

2) According to the pattern and color of the fabric, identify: the pattern and pattern of various fabrics are clear and clean on the front, with obvious pattern lines, distinct levels and bright colors; The reverse side is relatively light and fuzzy.

3) according to the fabric jacquard, jacquard stripes identification: jacquard fabric front stripes or patterns are more obvious, clear line outline, gloss are net and beautiful.

4) According to the identification of the fabric edge: the front side of the general fabric edge is smoother and clearer than the reverse side; the edge of the reverse side is curled inward. Some fabrics have words woven on the edge of the cloth. The words on the front are written clearly and smoothly, while those on the back are blurred.

5) Identification according to the factory seal: some fabrics are stamped with circular factory seals within 5cm of the corners at both ends, and the general seal is stamped on the front.

3. Shrinkage test

The reason for the shrinkage of the fabric is that the fabric itself has hygroscopicity and is drawn and bent during the weaving process. After printing and dyeing, it is elongated and widened, so that the fiber or yarn is continuously deformed by external force and is temporarily stable during drying. However, the deformed parts recover rapidly after encountering moisture and heating and ironing, thus causing severe shrinkage. The size of the shrinkage mainly depends on the mechanical strength of the textile production process, and is related to the size of the fabric warp and weft density. Commonly used fabric shrinkage test methods are the following four:

1. Natural shrinkage test

Through the method of ventilation, the fabric is naturally retracted by the influence of outside air, wind, light, heat and water vapor. The test method is to disassemble, relax and put the whole folded raw material for 24 hours and then retest to calculate the shrinkage rate.

2. Dry scalding shrinkage test

The dry ironing shrinkage rate refers to the degree of shrinkage of raw materials after heating by ironing. The method is to iron back and forth on the raw materials according to the highest temperature that the raw materials can withstand, measure its length and width after cooling, and then compare with the length and width of raw materials before ironing to calculate the shrinkage rate.

3. Spray shrinkage test

Water spray shrinkage refers to the shrinkage of raw materials by spraying water to make them damp. Spray the raw materials of the sample with clean water to make the water uniform, then knead the raw materials of the sample with hands, smooth them, dry them in the room with natural ventilation, iron them after drying, and calculate the shrinkage rate after not stretching.

4. Water immersion shrinkage test

Water immersion shrinkage test refers to immersing the sample raw material in water to make it shrink, immersing the sample raw material in clean warm water at 60 ℃, kneading it by hand, immersing it in water for 15 minutes, then taking it out, folding the sample raw material in half, then folding it into a square, pressing the water by hand, leveling it and drying it to calculate the shrinkage.

4. Discharge

The discharge requires reasonable sleeve discharge and reasonable splicing. Reasonable arrangement refers to the arrangement of drawing samples that save materials on the premise of ensuring the quality of clothing pieces. Sleeve is to make full use of parts and components of different shapes reasonable sleeve row. The parts and components of the garment are different. When drawing samples, we should make full use of the different angles, bending potential and other shapes of the clothing pieces for sleeve arrangement.

Reasonable discharge should be compact and reduce voids. Reasonable splicing. In order to improve the utilization rate of raw materials, appropriate splicing is allowed in the secondary parts of some parts. During the discharge, the splicing parts, the number of spliced pieces and the splicing locks shall be carried out in accordance with the relevant technical regulations and the requirements of the wearer, and the splicing seams and the splicing locks shall not be arbitrarily increased. Splicing must do the following:

1. Minimize sewing trouble

2. Comply with the splicing scope and silk lock regulations allowed by the product style

3. Obtain the wearer's permission

4. The splicing part shall be marked with the marking of the knife.

Single-piece discharge refers to single-piece cutting discharge, and industrial cutting generally refers to multi-piece discharge. There is a certain gap between the requirements of single-piece discharge and precision discharge, and the material saving is limited to a certain extent, so the consumption is more than that of general industrial discharge. Single-piece discharge is the basis of industrial discharge. To master the knowledge of discharge, we must first learn single-piece discharge. How to choose the best discharge scheme, in order to achieve the purpose of saving materials, is a continuous exploration of the subject. The basis of the arrangement is generally based on the style, and at the same time, the general common door width and plain clothing are the main, regardless of the pattern, pattern, reverse hair and other factors of the clothing. The style and structure of the discharge are different, and the number of materials used is not equal. Estimated material usage:

1.90cm wide (door width)

Jacket: can be cross cut: (length 7)× 2 sleeve length 7

Cut in the same direction: (length 7)× 2 sleeve length 6 collar width

Skirt: (skirt length 10)× 2

Pants: (pants length 10)× 2

2.144cm wide (door width)

Jacket: length 7 sleeve length 6

Skirt: skirt length 10

Pants: long pants

5. Cut

Cutting is a technical work, it is difficult to make up for the loss after the wrong. Therefore, cutting requires certain technical knowledge and practical operation experience, and only after repeated practical operation can we master the cutting technology.

Before cutting, carefully check the cut pieces, especially the more complex ones. Check whether the drawing line is clear, whether the contour line is obvious, and whether the positioning mark is fully drawn and accurately drawn. The quality requirements for cutting are as follows:

1. The cutting edges around the cutting piece shall be straight, round, smooth and square, and there shall be no skew notch or zigzag.

2. The combination of cutting pieces is accurate, and the left and right symmetrical cutting pieces should be symmetrical in length and size.

3. The eye knife and drill hole are accurate. The position of the eye knife and the depth of the eye knife should be accurate. Generally, it is appropriate to have a depth of 0.4~0.5cm at the 1cm seam. The depth of the eye knife is related to the texture performance of the raw material and the size of the seam. In principle, we can not only see the mark clearly, but also ensure that the eye knife maintains a certain fastness after sewing. The upper and lower layers of the drill hole are vertical, and the size of the drill hole is appropriate. As a drill hole with a fixed seam width, it should be drilled beside the seam to ensure that the drill hole is not exposed after the seam is sewn. The drill hole indicating the bag position should be drilled accurately according to the drawing sample, and cannot enter and exit again, so as not to expose the drill hole after bagging.
