  • How to calculation the price of grey cloth

    2022-01-07

    1. Yarn consumption Grey cloth is woven from warp and weft yarns. Knowing the amount of warp and weft per unit area of the grey fabric and the unit price of these yarns, the raw material price of the grey fabric can be calculated. Generally, you can know the amount of yarn used in the grey fabric ac Read More
  • What does yarn evenness mean?

    2021-12-31

    Evenness of yarn (Poor linear density, uniformity of linear density) Unevenness refers to the degree of variation in thickness along the length of the yarn, and can also be expressed as unevenness of yarn evenness. The quality of textiles depends largely on the yarn evenness. The unevenness of yarn Read More
  • What is the reason for the color not conforming to the standard sample due to the poor control of the dyeing process conditions and operation?

    2021-12-28

    a) The semi-products before dyeing do not meet the requirements. If the dyed semi-finished product has insufficient mercerization, the mercerization will be alkali-colored, which will change the shade. For example, after sulfide dyeing, the cloth surface will be red and not black.b) Hard water is us Read More
  • Light fastness

    2021-12-24

    Light fastness Sunlight has wave-particle duality, and the sunlight that transfers energy in the form of photons has a strong impact on the molecular structure of the dye. When the basic structure of the coloring part in the dye structure is destroyed by photons, the color of the light emitted by th Read More
  • The difference between flat screen printing and rotary screen printing

    2021-12-17

    Flat screen printing featuresThe printing method of the flat screen is that after the scraper runs in the weft direction, the cloth surface moves forward after the screen is lifted up and down, which is more suitable for patterns that express the pattern effect in the warp direction.Because it is a Read More
  • What are the requirements for temperature rise and fall in disperse dye dyeing?

    2021-12-14

    1) Heating requirements:Control the temperature rise, otherwise the temperature rises too fast, it will cause the dye to be dyed too fast, and the phenomenon of color difference will appear.① Colored flowers: refers to uneven dyeing.② Mid-way heat preservation (90℃*5') Purpose: to heat up the dye af Read More
  • The function and performance requirements of printing paste

    2021-11-26

    Printing paste refers to a polymer compound that acts as a thickening agent in the color paste and can be dispersed in water to make a thick colloidal solution with a certain concentration. In the actual textile printing process, the paste is the carrier that transfers the dyes and chemicals in the Read More
  • Classification of color fastness

    2021-11-19

    In the quality inspection of textile color fastness, rubbing color fastness is one of the very important inspection items, and the test result is directly related to the overall color fastness of the fabric. Because some dyes with poor color fastness can cause different degrees of harm to the human Read More
  • Rubbing Fastness

    2021-10-22

    Reasons for poor rubbing fastness:After the fabric is dyed, although the dye is combined with the fiber, there is a large dye concentration gradient between the dyed cloth to be tested and the white cloth to be tested. In the absence of external force, the molecules will spontaneously transfer from Read More
  • What are the comprehensive reasons for the production of colored flowers in dyeing?

    2021-10-05

    Unreasonable formulation of the process or improper operation produces color fretting;The process is unreasonable (for example, the temperature rises and falls too fast)Poor operation, knotting during dyeing, and power outage during dyeing;The temperature rises too fast and the heat preservation tim Read More
  • The impact of power rationing and production shutdown on us

    2021-10-01

    Looking back at the historical power curtailment situation, since 2003, China has had at least five large-scale “power curtailment”. The impact of “power curtailment” on the economy can generally be summarized into two aspects: on the one hand, continuous “power curtailment” directly Drag down indus Read More
  • What is the one-bath dyeing technique of nylon/cotton fabric

    2021-09-17

    Nylon/cotton fabrics are usually dyed by two-bath over-dyeing, that is, dyeing nylon with neutral, acid or disperse dyes, and then dyeing cotton with medium-temperature reactive dyes. The two-bath over-dyeing method is used for dyeing. The advantage is that the color (shade, shade) of nylon and cott Read More
