1. 100m dry weight : refers to the dry weight of 100m yarn . For example, the dry weight of the 100s yarn is 2.562g.
Second, the weight deviation : refers to the yarn weight deviation range of the specified unit length to ensure that the yarn count is unchanged.
For example: Is the weight deviation of a 21s yarn ±2% reasonable?
(1) 100-meter dry quantitative = number ÷ 1.085 ÷ 10 (2) number =
From the two formulas, we can find the 100-meter dry quantification of 20s, 21s, 22s, respectively, 2.687, 2.562, 2.443
Then, the deviation of ±2% from the 20-meter dry quantitative calculation of 21s is worth 2.510, 2.613, and does not exceed one count, so it is reasonable.
Third, the weight CV (%) : measure the unevenness of the weight of each yarn , also known as the coefficient of variation of the count.
4. Dry CV (%) : refers to the thickness and weight uniformity of the main body of the yarn .
1. CV value scientific name coefficient of variation, also known as standard deviation rate. It is a statistic that measures the degree of variation in each observation in the data. Its role is to reflect the degree of dispersion in the unit mean, which is often used in the comparison of the degree of dispersion of two or more population mean values. If the mean values ​​of the two populations are equal, the comparison standard deviation coefficient is equivalent to the comparison standard deviation.
2. The standard deviation is also called the mean square error. The standard deviation reflects the degree of dispersion of a set of data. If the average is the same, the standard deviation may not be the same.
3. For example: A: 45, 55, 65, 75, 85, 95 Average: 70 Standard deviation: 17.08
B: 67, 68, 69, 70, 71, 72 Average: 70 Standard deviation: 2.16
It can be seen that the degree of dispersion of B is less than A. The above example is the case where the average number of data in the two groups is the same, and it can be expressed by the mean square error. If the average is different, the CV value is used to indicate the degree of variation.
5. Breaking strength, breaking strength and breaking strength coefficient of variation CV (%) .
1. Breaking strength: refers to the maximum tensile force that the yarn can withstand. The unit is N (cattle). The test speed is 5 m/min.
2. Breaking strength: The maximum tensile force per tex. The unit is N/tex. Turks is the number of yarns .
3. Breaking strength coefficient of variation CV (%): the strength unevenness of the yarn .
Six, gauze: thick section +50%, detail -50%, neps +200%
1. Thick section +50%: The part where the yarn diameter exceeds 50% of the yarn body. Unit: unit / km.
2. Details -50%: Yarn diameter of less than 50% of the yarn main body portion. Unit: unit / km.
3. Neps: It is made of fiber, immature cotton or stiff cotton, which is caused by poor quality of the rolling mill or poor handling during spinning. More than 200% of the yarn body of the yarn body.
Seventh, twist : The yarn is rotated 360 degrees around its axis, which is a roundabout. The twist refers to the number of twists of the yarn within a certain length. Unit: 10cm
1. S捻: The direction of the fiber in the gauze is consistent with the middle of the letter S.
2. Z捻: The direction of the fiber in the gauze is consistent with the middle of the letter Z.
3. Generally, single yarns are usually Z捻, and strands are S捻.
4. When the yarn is twisted, the breaking strength increases, and the wrinkle resistance and wear resistance also increase. However, the twist cannot exceed a certain value, otherwise, the strength is lowered, and it is difficult to dye and fade.
8. Hairiness: Hairiness H value, standard deviation of hairiness Sh , coefficient of variation of hairiness CV h
1. hairiness H refers to a fiber length of yarn extending in vitro 1cm yarn measuring range, the total length in millimeters.
2. H hairiness number of the yarn number, the relevant twist, the finer the yarn its cross-section, the less the number of fibers, yarn hairiness outer projecting also at least larger twist yarn, twisted into the yarn hairiness vivo The greater the chance, the less hairiness.
3. The hairiness H value adversely affects the dyeing of the yarn .

The idea of JNPFOOTWEAR Women's Moccasins Collections is making the Women's Shoes with flat heel for a long walks. After we collect clients comments and feedbacks, we decide women's shoes should with

• Soft memory foam insole ( so we could feel cushion when walking)

• Flexible TPR outsole

• Wider last (cause 70% of shoes are export to western countries)

• Many colours to choose ( We have ladies white shoes, girls pink shoes,blacks shoes etc, many colours for summer & spring season to matching the clothes )

• Low MOQ (So our clients do not inventory pressures about ladies fashion colour shoes , which might only popular in one season)

We'd like to hear your ideas and comments too. Feel free to contact us. Wish we could develop a hot sale and unique women's shoes in your market.
