Description

Lightweight knitted fabric

The invention relates to a knitted fabric, in particular to a lightweight knitted fabric having a plaid pattern.

Since ancient times, people's pursuit of clothing has never stopped, from the initial shame to the present beauty, from the initial warmth to the present various functions. Nowadays, in the face of the ultra-high temperature summer, there is an urgent need for a fabric that is both thin and soft.

The light and thin fabrics currently on the market are classified into woven and knitted fabrics. Among them, woven fabrics occupy a large part of the market due to their light weight and high strength, especially in order to increase the apparent appearance of the fabric, and by adjusting the fiber type and proportion of the warp and weft yarns, the plaid-shaped lightweight fabric is greatly affected. Consumers love it, but the softness and stretchability of such fabrics are not enough to meet people's needs. Although knitted fabrics are superior in flexibility and stretchability to woven fabrics, they are difficult to combine at the same time with lightness and highness. The burst strength, so the market share is less, but there are also many related developments.

For example, a weft-knitted small square fabric disclosed in Chinese Patent Document CN201120289351.0 includes a horizontally arranged spun yarn woven area and a vertically arranged roving needle-drawing area, and the square effect is obvious, thereby improving the moisture wicking property of the fabric, The appearance is improved, the hand feels soft and the elasticity is good, but the fabric is a double-sided woven fabric. Although the use of the thick roving yarn reduces the weight of the fabric to a certain extent, the weight is reduced, but still needs to be further improved. Step improvement.

Another example is a new type of hollowed out cloth disclosed in Chinese patent document CN201320459035.2. The jacquard weaving area is formed into an opaque square lattice and a polyester fiber monofilament weaving area to form a transparent square lattice, such a combination can be increased. The layering of the hollow cloth reduces the weight of the fabric, but because the enamel and the polyester monofilament are used interchangeably, the formed pattern tends to be horizontal stripes; and the use of the jacquard machine correspondingly increases the processing cost.

In addition, the weaving cost of the single weft knitting machine is low, the gram weight of the obtained woven fabric is lower than that of the double woven fabric of the same specification, but the breaking strength is difficult to meet the requirements; and the single weft knitting machine has only four needle paths. The horizontal reinforcing stripe structure can be easily realized, but the longitudinal reinforcing stripe is difficult to achieve.

In view of the above problems, an object of the present invention is to provide a single-face knitted fabric which is low in cost, soft to the touch, low in weight (lightweight), and high in strength.

Technical solution of the invention:

Knitted fabrics of the present invention is a grid pattern on one surface loop weft units thereof; and the knitted fabric having a grammage of 30 ~ 90g / m ^2, a burst strength of more than 300KPa.

The knitted fabric of the invention solves the problem of low breaking strength of the single-face knitted fabric by the plaid pattern circulation design, improves the wearing performance of the fabric, and at the same time gives the fabric a more unique appearance, and solves the apparent monotonicity of the thin and light fabric. The problem has greatly satisfied people's pursuit of individualized clothing; and the hand feels soft and delicate, and the texture is light.

Figure 1 is a schematic diagram of a single-sided plaid pattern.

The lightweight knit fabric of the present invention is a single weft knit fabric composed of a plaid pattern circulation unit. The plaid pattern circulation unit here is composed of a frame and a filling area inside the lattice, wherein the frame (horizontal and longitudinal) is arranged in a circle by the same kind of yarn; the filling area inside the lattice is made of another kind of yarn (such as different materials or denier) Differently arranged in a circle, the border yarn is not looped in this area, which produces a lattice effect, and at the same time ensures that the fabric is still qualified even if the weight is reduced.

The lightweight knitted fabric of the present invention has a burst strength of 300 KPa or more and a basis weight of 30 to 90 g/m ² . Under the premise of ensuring that the breaking strength is acceptable (the JIS standard specifies 294 KPa), it is impossible to achieve a basis weight of the knitted fabric of 30 g/m ² or less.

The size of the plaid pattern loop unit is also related to the burst strength and lightness of the thin fabric. In each of the plaid-type circulation units of the present invention, the number of coils of the preferred vertical frame is 3 to 36, and the number of coils of the horizontal frame is not less than 5. If the number of coils of the vertical frame is less than 3 and the number of coils of the horizontal frame is less than 5, the size of the plaid pattern is small, and the apparent fineness of the frame is larger than the fineness of the apparent yarn of the filling area, and the filling is performed. The proportion of the apparent yarn in the area is reduced, so that the feel of the fabric becomes rough and the weight is increased, which is not conducive to weight reduction. The size of the plaid pattern should be determined according to the fineness of the yarn of the frame. The larger the fineness of the yarn on the frame, the larger the plaid pattern can be selected; the number of stitches of the horizontal frame of the lattice circulation unit of the present invention is more Good for 5~36 (small jacquard machine up to 36).

In order to obtain a light and thin effect, the fineness of the yarn used in the lattice frame and the filling area must be low, taking into account the lightweightness of the fabric and the possibility of braiding conditions (the fineness of the non-elastic yarn is less than that of the 20D circular knitting machine). The fineness of the preferred frame of the present invention is 30 to 80 denier, more preferably 40 to 60 denier when the filament is multifilament yarn; When the yarn of the frame is a spun yarn, the fineness is 80 to 100, more preferably 80. The apparent yarn in the filling zone is 20 to 50 denier, more preferably 20 to 40 denier when the filament is multifilament, and the fineness of the superficial yarn in the filling zone is 80 to 100, preferably 100. At the same time, it is considered that if the fineness of the apparent yarn of the filling zone is larger than the fineness of the apparent yarn of the frame, the surface of the fabric exhibits a vertical and horizontal groove effect, which is not conducive to the improvement of the breaking strength of the fabric, and thus the apparent yarn of the filling zone. The proportion of the larger, will affect the lightweight of the fabric. Therefore, it is required that the fineness of the frame appearance yarn of the present invention is larger than the fineness of the apparent yarn of the filling zone. If the fineness of the apparent yarn in the frame and the filling area is too large, the fabric cannot be made lightweight. When the yarn used is a spun yarn, since the strength of the spun yarn is lower than that of the filament multifilament, in order to obtain a fabric of the same strength, the spun yarn used has a fineness larger than that of the filament multifilament. In addition, the fineness of the yarn in the filling zone is fine, and a strong sense of perspective can be obtained. It should be noted that, in the above, the fineness of the spun yarn is counted, and the higher the value of the count, the smaller the fineness of the yarn. Danny and the count can be converted according to "Danny = 5315 / count".

In the lightweight knit fabric of the present invention, the fiber raw material of the lattice border apparent yarn and the fiber raw material of the lattice filling zone apparent yarn are not particularly limited, and may be chemical fibers or natural fibers. The cross-sectional shape of the chemical fiber may be a circular shape, or may be a triangular shape, a quadrangular shape or the like; and may be full extinction, semi-dull, gloss, or the like. As we all know, nylon fiber has high strength and wear resistance and good water absorption, which can impart high burst strength and wearing comfort to light and thin fabrics; polyester fiber fiber has the characteristics of corrosion resistance, straightness, smoothness, easy washing and quick drying. It imparts good shape retention and "iron-free" properties to lightweight fabrics; cotton and viscose fibers are natural fibers with pure natural softness and excellent water absorption, making them excellent candidates for underwear materials. Therefore, the fiber raw material of the lattice border apparent yarn is preferably in nylon, polyester fiber, cotton or viscose. One. Preferably, the fiber raw material of the lattice-filled surface of the yarn is at least one selected from the group consisting of nylon, polyester fiber, cotton or viscose; for example, nylon/viscose blended yarn, polyester fiber/viscose blended yarn, polyester fiber/ Cotton blended yarn, nylon spun yarn, polyester spun yarn, pure cotton yarn, nylon filament, etc., but is not limited thereto.

In view of the wearing comfort of the final product, it is preferred to impart a certain elasticity to the lightweight knit fabric of the present invention. In the present invention, the lattice frame serves as a shape retaining function in addition to the appearance aesthetics and the reinforcing function, so that the elastic yarn is not suitable; and the lattice filling area functions to ensure the lightweightness of the fabric, so in this area There is no problem in using elastic yarns. The elastic yarn used herein is not particularly limited and may be an elastic fiber bare yarn, an elastic fiber covered yarn, an elastic fiber core yarn or a high elastic filament (polybutylene terephthalate fiber, poly pair). The propylene terephthalate fiber, the polybutylene terephthalate fiber/polyparaphenylene glycol fiber, etc., is preferably an elastic fiber bare wire, and the content thereof is 5% to 10%.

The lightweight fabric of the present invention has a light weight index of less than 0.3 g/m ² . KPa, when the strength and lightness index is 0.3g/m ² . When KPa is above, there may be two cases, that is, the gram of the fabric is greater than 90g/m ² or the rupture strength is less than 300KPa; the smaller the strength and lightness index, the better the combination of the lightweightness and the rupture strength of the fabric. . The weight of the existing thin and light single-knit fabric is generally 110 g/m ² or more. Under the same conditions, the fabric of the invention has superior lightness and burst strength. Compared with the existing equivalent knitting conditions, the plaid fabric formed by the stylus or two different types of yarns has a lot of rupture strength, and the plaid stripe effect with vertical and horizontal bulging is formed, which is unique. Appearance style, in addition, also makes the fabric with excellent shape retention.
