Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of Chinese Patent Application No. 201310537564.4, filed on Nov. 4, 2013 and Hong Kong Patent Application No. 13112395.1, filed on Nov. 4, 2013, the entire content of which is hereby incorporated by reference.

FIELD OF THE TECHNOLOGY

The present application is related to a fully spandex weft-knitted cloth and production method thereof and a kind of lingerie lining, which belongs to textile technology field.

BACKGROUND

In the process of weft-knitting, cotton or fiber is mainly applied, while spandex filament is secondarily applied for producing cloth. The cloth surface effect is mainly reflected with the specific texture of cotton or fiber, if certain specialized cloth requires a very high resiliency (such as joining area of lingerie and lining of bra), common cloth normally cannot satisfy such expectation.
Therefore, inventing a fully spandex weft-knitted cloth and production method thereof to meet the market demand is one of the dilemmas that the present field seeks to solve.

SUMMARY

The present application provides a production method of a fully spandex weft-knitted cloth and includes the following steps:
Weft knitting 40 D and/or 70 D spandex filament on a double-sided knitting machine (also known as the double-sided large circular machine). The weft-knitting includes needle-containing (tuck) weaving the spandex filament with the needle of the upper needle dial, at the same time, needle-containing (tuck) weaving with the needle of the lower needle dial, forming needle-containing double-sided stitches. Then, needle (wreathe) weaving the spandex filament with the needle of the upper needle dial while without the needle of the lower needle, and forming upper single-sided stitches. Further, needle (wreathe) weaving the spandex filament with the needle of the lower needle dial while without the needle of the upper needle dial, forming lower single-sided stitches and completing a weaving cycle. A fully spandex weft-knitted cloth is obtained by completing one or a plurality of the weaving cycles.
In the production method of the above fully spandex weft-knitted cloth, optionally, the yarn length of the upper single-sided stitches and lower single-sided stitches is 12-14 cm/100 G. The yarn length of the needle-containing double-sided stitches is 14-15.5 cm/100 G.
In the production method of the above fully spandex weft-knitted cloth, optionally, the delayed gap between the needling of the needle of the upper needle dial and the needling of the needle of the lower needle dial is three needles.
The present application also provides a fully spandex weft-knitted cloth, which is produced from the production method of the above fully spandex weft-knitted cloth.
The present application also provides a lingerie lining, which includes the above fully spandex weft-knitted cloth.

The production method of a fully spandex weft-knitted cloth includes the following steps:
As FIG. 1 illustrates, weft-knitting is performed on the above double-sided large circular knitting machine applying spandex filament. The method of weft-knitting includes: needle-containing (tuck) weaving the spandex filament with the needle of the upper needle dial, at the same time, needle-containing (tuck) weaving with the needle of the lower needle dial. The delayed gap between the needling of the needle of the upper needle dial and the needling of the needle of the lower needle dial is three needles, forming needle-containing double-sided stitches 1. Then, needle (wreathe) weaving the spandex filament with the needle of the upper needle dial while the needle of the lower needle dial does not perform weaving, forming upper single-sided stitches 2. Further, needle (wreathe) weaving the spandex filament with the needle of the lower needle dial while the needle of the upper needle dial does not perform weaving, and forming lower single-sided stitches 3 and completing a weaving cycle. In other word, according to FIG. 1, the stitches are arranged in angularity. The stitches form one weaving cycle in every three molds which include needle-containing double-sided stitches 1, upper single-sided stitches 2 and lower single-sided stitches 3. A fully spandex weft-knitted cloth is obtained after completing one or a plurality of weaving cycles.
As the fully spandex weft-knitted cloth in the present application applies spandex with melting and shaping properties for performing weaving, the cloth obtained can possess greater flexibility and firmness, allowing it to achieve a fitting effect incomparable by other products, and can be added into every kind of lining in clothing to increase its firmness and flexibility based on different needs.
Gripping (parameter) testing is performed on the cloths obtained that applied different raw materials and different weaving methods. The result obtained is shown in Table 1. In particular, the warp-knitting applied is commonly used warp-knitting in the present field. The weft-knitting applied is weft-knitting in the production method of the present application. It can be seen from the data in Table 1, the gripping (parameter) testing result of the fully spandex weft-knitted cloth in the present application far surpassed the testing results of cloths produced from other raw materials and weaving methods. The fully spandex weft-knitted cloth in the present application definitely possesses better flexibility.

The production method of the fully spandex weft-knitted cloth in the present application revolutionalized the use of raw materials in the weaving production distinguished from traditional practice and inventively applied spandex filaments. No matter whether it is the weft-knitting weaving production, or the textile materials and clothing capability aspects, the present application is an important and novel break-through. The production method in the present application applies specialized weaving method, and a fully spandex cloth can be weaved out using a double sided knitting machine (including rib knitting machine). Since the spandex with melting and shaping properties is applied for weaving, the cloth obtained can possess greater flexibility and firmness, allowing it to achieve a fitting effect incomparable by other products and can solve the inflexible characteristic of general cotton and fiber cloths due to weaving too densely which would result in loosening and finally causing flabbiness of the cloth surface incapable of achieving firmness. Since the fully spandex weft-knitted cloth in the present application possesses the capability of high gripping parameter, it can fit comfortably on the surface of skin and prevent the situation of relocation or fall off of the clothing due to motion of the wearer. Hence, it can be applied to lingerie lining, underwear border, clothing or pant border during weaving of cloths and can be used as a type of cloth when large flexibility is required and which effect cannot be achieved using fiber and cotton.
