Description
Technical Field
The invention relates to a sun-proof fabric and a production process thereof, in particular to a light and thin breathable sun-proof fabric and a weft knitting production process thereof.
Background
Research proves that ultraviolet rays can cause the reduction of human immune function, deeply injure genetic factors, and cause the increase of the incidence of skin cancer, cataract, pigmented spot cancer and the like. Human beings are gradually aware of various hazards of ultraviolet rays to human health, and various developed sunscreen creams and ultraviolet-resistant cosmetics are favored by consumers, especially female consumers. However, sunscreen cosmetics contain various heavy metals, and cause certain damage to human health after long-term use. The sunscreen cosmetics also need to be removed by using a cleaning product before sleeping at night, and incomplete makeup removal can cause pore blockage and cause more damage to skin. Therefore, people aim at the research of ultraviolet-proof textiles and develop sunshades, hats, sun-proof clothes and the like with ultraviolet-proof function.
The sun-blocking clothes in the market at present are various in style, and are designed to be eight-door-five, wherein the sun-blocking clothes with the hat, the long sleeves and the finger sleeves can protect the skin to the maximum extent, and the skin such as the face, the back neck, the arms and the like which are easily exposed outside can be prevented from being damaged by ultraviolet rays. The sun-blocking clothes are easy to put on and take off, convenient and free, and can be taken off at any time when people are engaged in indoor operation without being bound.
The conventional sun-blocking clothes all use woven fabrics, the woven fabrics have the characteristics of stable size, stiffness, small meshes and the like, the ultraviolet penetrability is low, but the biggest characteristic is that the air permeability and the moisture permeability are not good, and if the woven fabrics with poor air permeability and moisture permeability are used for wearing in summer, the wearing experience of a wearer is seriously influenced.
At present, the demand of sun-blocking clothes market is increasing year by year, and the sun-blocking clothes have good application prospect. Therefore, more and more attention is paid to designing and developing a textile fabric with an ultraviolet-proof function, and a fabric with a strong sun-proof function, ventilation and cooling is the key of sun-proof clothes.
The knitting technology is divided into warp knitting and weft knitting, and both the warp knitting and the weft knitting can be used for producing the sun protection clothes. Although both the two parts are formed by threading the coil, the equipment selection, the process, the coil forming method and the like have great differences. Weft knitting machines are generally circular row needles, known as circular machines, also known as knitting machines. The crochet hook carries the yarn and penetrates into the loop formed by the previous needle in sequence to form a new layer of loop, and the yarn is circularly knitted. Tens of yarns can be woven by the circular knitting machine rotating for one circle, so that weft knitting is a weaving method with higher efficiency. Compared with the warp knitting process, the weft knitting process has shorter flow, does not need the warping process of warp knitting, is not as good as the warp knitting production process in production efficiency, but has cheaper price and better competitiveness as well as warp knitting fabrics.
The weft-knitted sun protection garment is formed by threading the loops, has better air permeability and more comfortable wearing compared with woven fabrics, and is particularly suitable for being worn in hot environments in summer. Compared with woven fabrics, the production process of the weft-knitted fabrics is shorter, processes such as weaving and spooling and sizing are not needed, the production efficiency is higher, and the cost is lower.
Disclosure of Invention
The invention aims to solve the technical problem of providing a light and thin breathable sun blocking fabric and a weft knitting production process thereof.
The invention is realized by the following steps:
the main body of the light and thin breathable sun-blocking fabric is formed by weft knitting and knitting uvioresistant functional yarns, and comprises a non-perspective main body which is continuously and tightly knitted and a linear strip-shaped perspective part which is formed by a loop transfer structure.
Further, the non-perspective main body and the perspective part are both weft plain stitch structures.
Further, a piece of 100-30D spandex is padded in the weft plain stitch.
Further, the anti-ultraviolet functional yarn is full-dull fine denier polyester filament FDY.
The production of the uvioresistant functional yarn is prepared by blending spinning, namely, powder of the ultraviolet absorbent or the ultraviolet screening agent is added or directly blended and spun during the polymerization of the polymer, or ultraviolet-proof master batches can be prepared firstly and then spun. The sun-proof fiber produced by the method has the advantages of lasting sun-proof degree, washing resistance and soft hand feeling. By changing the amount of the added anti-ultraviolet powder and the difference of the uniformity of the grains, the obtained fabric has different anti-ultraviolet grades, and is suitable for the individual requirements of different outdoor operations.
The invention also provides a weft knitting production process of the light and thin breathable sun-blocking fabric, which comprises the steps of raw material weaving, slitting, pretreatment, pre-shaping, dyeing and shaping, wherein a weaving machine adopts a single-sided circular knitting machine with large cylinder warp, and the yarns of the fabric main body are formed by 100-10D chemical fiber filament weft knitting with the ultraviolet resistance function.
The fabric main body comprises a non-perspective main body and a perspective part, the non-perspective main body and the perspective part both adopt a weft plain stitch structure woven by fine denier polyester filaments, the perspective part pulls coils through loop transfer to form straight stripe patterns in a straight line shape, and meanwhile, a 100-30D spandex is padded in the weft plain stitch structure.
The yarn feeding amount of the perspective part is at least 100 needles and 10 mm.
The invention has the following advantages: the light and thin breathable weft-knitted fabric is divided into two different parts, wherein one part is a non-perspective main body which is continuously and tightly knitted, the other part is a linear strip-shaped perspective part which is regularly and loosely knitted, the non-perspective main body and the perspective part both adopt a weft plain stitch structure which is knitted by fine denier polyester filaments, and the weft plain knitted fabric has larger stretching deformation characteristics in the longitudinal direction and the transverse direction. When knitting, the yarn feeding amount of the perspective part is at least 100 needles and 10mm, and a straight stripe pattern can be formed by transferring and pulling the coil. In the loose-holding state, the coil exists in a bending state, and after the coil is stretched, the structure and the shape of the coil are changed, the contact position between the coils is shifted, and a part of a line segment which is originally bent is changed into a straightening state. Therefore, the weft plain knitted fabric is used as a basic structure, and has the characteristics of simple result and excellent elasticity. The perspective part is combined with the non-perspective part, the perspective part has better air permeability, and the non-perspective part has good ultraviolet resistance, so that the fabric has air permeability and ultraviolet resistance, and has good clothing performance.
Meanwhile, in order to ensure the elastic stretching of the fabric and ensure that the clothes performance has good wearing feeling, an elastic yarn is selected to be lined into the coil in a lining mode to form an unclosed suspension arc, the consumption of spandex is low, and the cost of the fabric is reduced. The fabric can not only be sun-proof in high efficiency, but also absorb moisture and perspire, and has good moisture absorption and quick drying performance.
