Please describe the morphological characteristics of the six complex yarns

There are two main types of complex yarns: fancy yarn and textured yarn.

1. Fancy yarn: Fancy yarn refers to the yarn with special structure and appearance effect obtained by using special raw materials, special equipment or special technology to process the fiber or yarn in the process of spinning and threading, and is a kind of decorative effect in yarn products.

It is divided into four categories according to different processing methods.

1. Fancy yarn processed by ordinary spinning system, such as color spinning, silk thread, etc.

2. The fancy yarn processed by the dyeing method is called the pattern yarn.

3. The fancy yarn processed by the fancy twisting machine is divided into overfeed type and control type according to the feeding speed of the core thread and the decorative thread.

4. Special fancy threads, such as gold and silver threads, chenille threads, corespun threads, brushed threads, flocking threads.

2. Textured yarn: a yarn with high fluffiness and elasticity made by using the characteristics of synthetic fibers that can be plasticized and deformed after being heated.

There are two main forms.

1. Staple fiber yarn is mainly in pursuit of fluffiness, referred to as bulky yarn. It is characterized by a fluffy volume, a soft feel, and a high degree of compressive elasticity, such as acrylic expanded staple fiber yarn.

2. The chemical fiber filament yarn, referred to as elastic yarn, which is mainly based on the pursuit of telescopic elasticity, can have large elongation deformation and deformation recovery ability under the action of small load external force.

When a population grows in a finite environment, as the population density rises, the intraspecific struggle between individuals for limited space, food and other living conditions will inevitably intensify, and the number of predators feeding on the population will also increase, which will reduce the birth rate of the population and increase the mortality rate, so that the growth rate of the population (refers to the instantaneous growth rate under the condition of a certain population at a certain time, which can be expressed by dn dt) decreases, and when the population reaches the maximum capacity (k value) allowed by the environment, The population will stop growing, i.e. the growth rate will be 0 at this point, and sometimes it will remain relatively stable around the maximum. When the population grows to a value of 1 2k, there is an inflection point p in the curve, and the population grows at the fastest rate at point p and provides the most resources without affecting the regeneration of resources. When greater than 1 2k values, the rate of population growth will begin to decline.

Therefore, in the rational development and utilization of wild animal and plant resources, when the population is greater than 1 2k value, a certain amount of the biological resource can be hunted, and the amount obtained is the largest, when the population size is less than 1 2k value due to excessive hunting, the growth rate of the population will slow down, the amount of resources obtained will also be reduced, and the regeneration of resources will be affected. Therefore, when hunting resources, attention should be paid to ensuring that the remaining amount is above 1 2k value, which will be conducive to the regeneration and sustainable development of resources.

Answer]: The yarn classification method is as follows:

1. Classification according to yarn raw materials: it can be divided into pure spinning yarn and blended yarn.

2. Classification according to the thickness of the yarn empty leakage wax line: it can be divided into coarse special yarn, medium special yarn, fine special yarn and extra fine special bucket sliding yarn.

3. Classification according to spinning system: it can be divided into worsted yarn, woolen yarn and waste spinning yarn.

4. Classification according to spinning method: it can be divided into ring yarn, free end yarn, airflow yarn, electrostatic yarn, vortex yarn, dust cage yarn, non-free end yarn, self-twisting yarn, air-jet yarn and core-spun yarn.

5. Classification according to yarn structure: it can be divided into single yarn, strand, monofilament, textured yarn, high-elastic yarn, low-elastic yarn, bulky yarn, network yarn and fancy yarn.

6. Classification according to the use of yarn: it can be divided into weaving yarn, knitting yarn and other yarns.

6 characteristics of Dry M yarn.

Dear, we are glad to answer for you: 6 characteristics of dry M yarn? A:

Dry M yarn does not have 6 characteristics. 1) Different spinning methods have different effects on the yarn structure, the branch structure of staple fiber yarn is different from that of filament, first of all, the arrangement of the outer and internal fibers of the yarn, and the external structure includes the appearance and surface structure of the yarn. Such as:

the arrangement of the fibers on the yarn surface; hairiness of yarn; coefficient of friction of yarn; characteristics of yarn; Abrasion resistance and other surface properties of yarn. (2) The internal structure of the yarn is mainly the entire cross-section of the fiber body and the longitudinal arrangement of the yarn, and the internal structure of the fiber orientation, elongation, displacement and twist includes the strength of the yarn; degree of fiber mixing; flexural strength; compressibility; Resilience (tendency to knot).

The advantages and disadvantages of fancy yarn and the characteristics of its three basic components are briefly described.

Dear, hello, the dismantling brigade has found a brief description of the advantages and disadvantages of fancy yarn and the characteristics of its three basic components. The advantage of the brigade stupid stool is that the fancy yarn is beautiful in shape and has many uses, but the disadvantage is that it is not durable, not wear-resistant, and the quality is slightly worse. Fancy yarn refers to the yarn with special structure and appearance effect obtained by processing the fiber or yarn by using special raw materials, special equipment or special technology in the process of spinning and thread-making, and is a kind of yarn with decorative effect in yarn products.

Fancy yarn varieties are ever-changing, and are generally composed of a combination of core thread, decorative thread and consolidated thread to form a hailstone.

Answer]: Suit line Special fancy line.

Analysis: Fancy yarn refers to the yarn that obtains special appearance, feel, structure and texture through various processing methods, including fancy thread, pattern thread and special fancy thread.

The color line refers to the yarn that mixes the colored fiber into the fiber of the base yarn in a certain proportion, so that the yarn presents a distinct length, different sizes of color segments, and color dots, such as color dot line, rainbow line, etc. This yarn is mostly used for ** and men's jackets.

Fancy thread refers to the yarn with special structure and appearance effect obtained by processing the fiber or yarn by using special raw materials, special equipment or special technology in the process of spinning and thread making, and is a kind of yarn with decorative effect in yarn products. Almost all natural fibers and common chemical fibers can be used as raw materials for the production of fancy threads, which can be made of silk, pressed silk, silk, rayon, cotton yarn, hemp yarn, synthetic fiber, gold and silver thread, blended yarn, human cotton, etc. Various fibers can be used separately or mixed with each other, learning from each other's strengths and weaknesses to give full play to their inherent characteristics.

Special fancy threads mainly refer to filigree, chenille threads, etc. Gold and silver wire mainly refers to the gold and silver wire obtained by sandwiching aluminum sheets between polyester film sheets or steaming on polyester films. It can be used both on fabrics and as decorative sewing threads to make the surface of the fabric shiny and bright.

Chenille thread is a special fancy yarn that holds the fibers on a core yarn that is held in the strands, like a bottle brush. It has a soft feel and is widely used in flocking fabrics and tasseled fabrics.

Answer] Pei Ji Jujube: Correct.

Analysis: When the fiber length is long and the fiber is fine, the friction resistance between the fibers in the yarn is larger, and it is not easy to slip, so the yarn strength is higher and the yarn is disassembled. When the length of the fiber is neat, the fiber is fine and the lead is even, the yarn strip is evenly dry, and the weak ring is few but not significant, which is conducive to the improvement of the yarn strength.
