Problems solved by technology

However, when some special fabrics require high elasticity, such as the joint parts of women's underwear and the inner lining of bras, ordinary gray fabrics often cannot meet their requirements
If the spandex content exceeds 30%, production difficulties will be greatly increased. For example, even if the coils fall off somewhere in the tissue, longitudinal detachment will occur, which is easy to burst the yarn, and the production efficiency is low. The cloth surface is horizontal and the spandex quality ratio is high A series of production problems such as weaving difficulties, dyeing stains, different colors on the bottom surface, etc.
[0004] In addition, women often worry about the selection of underwear when they need to wear tube top dresses for evening parties. They need to be body-shaping, non-slip and beautiful. , the human body often feels tight and uncomfortable during wearing, and even produces strangulation marks

Embodiment 1

[0031] This embodiment provides a kind of high-elastic sticky weft knitted fabric and its preparation method. The weaving process of the preparation method is as follows: figure 1 As shown, the preparation method specifically includes the following steps:

[0032] Weave 20D H-550SPANDEX low-temperature spandex yarn and 30D / 34F NYLON6 nylon filament through "28G 34" double-sided large circular machine (SANTEC) by weft knitting method:

[0033] Knit 20D H-550SPANDEX low-temperature spandex yarn with needles (tuck) on the knitting needles of the upper dial, and at the same time knit with needles (tuck) on the knitting needles of the lower dial to form a double-sided structure with needles 1, with needles Double sided tissue 1 as figure 1 The needle-containing double-sided tissue shown in 1;

[0034] Then 20D H-550SPANDEX low-temperature spandex yarn is woven on the knitting needles of the upper dial and the knitting needles of the lower dial are not knitted to form the upper un...

Embodiment 2

[0045] This embodiment provides a high elastic sticky weft knitted fabric and a preparation method thereof, the preparation method specifically comprising the following steps:

[0046] Weave 70D SPANDEX low-temperature spandex yarn and 50D / 34F NYLON6 nylon filament through "28G 34" double-sided large circular machine (SANTEC) by weft knitting method:

[0047] 70D SPANDEX low-temperature spandex yarn is knit with needles (tuck) on the knitting needles of the upper dial, and at the same time knit with needles (tuck) on the knitting needles of the lower dial to form a double-sided weave with needles;

[0048] Then weave 70D SPANDEX low-temperature spandex yarn on the knitting needle of the upper dial and keep the knitting needle of the lower dial from knitting to form the upper unilateral weave;

[0049] Then knit 70D SPANDEX low-temperature spandex yarn and 50D / 34F NYLON6 nylon filament at the same time on the lower dial needle (knitting) and keep the upper dial needle from knit...

Embodiment 3

[0053] The high elastic sticky hand weft knitted fabrics prepared in Examples 1 and 2 were tested for friction performance with the fabrics prepared by using different raw materials and different weaving methods, and the test results are shown in Table 2. Wherein, polyester+spandex and cotton+spandex are the corresponding fabrics obtained by weaving through conventional weft knitting methods in this field.

[0054] Table 2

[0055]

[0056]

[0057] As can be seen from the data in Table 2, the friction coefficient of the spandex surface of the fabrics made in Example 1 and Example 2 is significantly better than the test results of other components, indicating that the fabrics made by the preparation method of the present invention have sticky and non-slip properties. performance and good adhesion.

Abstract

The invention discloses high-elasticity sticky weft knitted fabric, a preparation method and an application thereof, and a lingerie liner with the high-elasticity sticky weft knitted fabric. The preparation method includes that carrying out weft knitting on 20D and / or 70D low-temperature polyurethane filament and 30D and / or 50D nylon to form a tissue structure comprising pin double-sided tissue, upper single-side tissue and lower single-side tissue, and knitting circularly to obtain the high-elasticity sticky weft knitted fabric, wherein the mass content of the polyurethane in the high-elasticity sticky weft knitted fabric is larger than 50%. The high-elasticity sticky weft knitted fabric is prepared through the preparation method. The high-elasticity sticky weft knitted fabric can be used for manufacturing high-elasticity underwear, strapless gown underwear, shapewear, sports underwear, swimsuit, chest liners, side corsage wings, corsage buckle belts, lovers' clothes and kicking straps. The high-elasticity sticky weft knitted fabric is double-faced weft knitted fabric, wherein one face is nylon while the other face is polyurethane; the high-elasticity sticky weft knitted fabric is high in elasticity, sticky performance and polyurethane content and difficult to deform.

Description

technical field [0001] The invention relates to a preparation method of a braided fabric, in particular to a preparation method of a double-sided weft knitted fabric with nylon on one side and spandex on the other side with high elasticity and stickiness, and belongs to the technical field of textiles. Background technique [0002] Because the stability of knitted fabrics is not as high as that of woven fabrics, and knitted fabrics are wound by a strand of yarn to form coils, and then the coils are connected to form fabrics, so knitted fabrics are highly elastic and unstable. , has stretchability in the process of drying or exercising, but it is easy to lose shape. Because spandex has high elongation at break (above 400%), high extensibility (500%-700%), and low elastic modulus (200%, Elongation 0.04-0.12g / d) and high elastic recovery rate (200%, elongation 95%-99%), therefore, knitted fabrics are usually mixed with a small proportion of spandex to improve stretchability, re...
