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 warp knitting production process thereof.
Background
Ultraviolet rays are the most major cause of premature skin aging, and long-term ultraviolet radiation causes photoaging of the skin and even skin cancer. In summer, the sunlight is strong, and direct irradiation to the skin can cause erythema, darkness and even sunburn of the skin layer. People can take measures to protect other exposed skins besides applying sunscreen cream to protect own faces, and sun-proof clothes become a poor choice for body sun-proof. When the clothes with the ultraviolet-proof function are worn in hot seasons, sweat can be quickly led out to the surface of the fabric from the skin and is dried quickly, and the trouble of sweat wetting is avoided. Therefore, the clothes are usually made of light-weight and soft-touch fabrics, are breathable and windproof, are comfortable to wear, and can enable a wearer to keep a fresh body feeling in outdoor activities. The sun-blocking clothes can obtain the ultraviolet-proof function in two ways, namely, a coating containing an ultraviolet-proof auxiliary agent is coated on the surface of the fabric, and the auxiliary agent containing the ultraviolet-proof function is added in the after-finishing of the fabric dyeing process.
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 worn by clothes in summer, the wearing experience of a wearer is seriously influenced.
Both warp and weft knitting techniques can be used to produce sun protection clothing. Although both the two are formed by threading the coil, the equipment selection, the process, the loop forming mode and the like have great differences. In weft knitting machines, which are generally circular row needles, called circular machines, also called knitting machines, the crochet hook carries the yarn to penetrate into the loops formed by the last needle in sequence, forming a new layer of loops, and knitting the yarn in a circular manner. The outer surface of the warp knitting machine is similar to that of a knitting machine, all yarns are wound on a warp beam, the warp beam is positioned behind and above a knitting area, and all yarns are fed into the knitting area at the same time. During the sleeving process, each yarn is controlled by a separate needle. Warp knitting differs from weft knitting in that the loops formed are arranged in the vertical or warp direction and are formed by the overlapping of adjacent yarns.
Compared with weft knitting technology, the warp knitting technology has more warping processes, although the equipment price is higher than that of a weft knitting machine, the production efficiency is far higher than that of the weft knitting production technology, so that the production cost is almost the same as that of weft knitting, and the warp knitting technology has better competitiveness with weft knitting fabric.
The warp knitting fabric is formed by threading the coils, so that compared with a woven fabric, the warp knitting fabric has better air permeability and is more comfortable to wear, and the warp knitting fabric is particularly suitable for being worn in hot environments in summer. The production process of the warp-knitted fabric is short, processes such as weaving and spooling and sizing are not needed, the production efficiency is high, and the cost is low.
Disclosure of Invention
The invention aims to solve the technical problem of providing a light and thin breathable sun-blocking garment fabric and a warp knitting production process thereof.
The invention is realized by the following steps:
a light and thin breathable sun-blocking garment fabric comprises a fabric layer, wherein an ultraviolet-proof finishing agent is padded on the surface of the fabric layer; the fabric layer comprises an elastic layer, a base fabric layer and a check pattern layer which are formed by warp knitting (the layer structure formed from inside to outside is the elastic layer, the base fabric layer and the pattern layer in sequence).
Further, the checkered layer is formed by weaving 100-10D chemical fiber filaments.
Furthermore, the checkered layer is formed by weaving warps and wefts, weft yarn lapping numbers are 10/01// open-end chains, and radial transverse strips adopt (10/12) × 3/10/23// variable structures.
Furthermore, the weft-wise lines are woven in a threading mode of 1-threading and 3-empty-threading to form spaced longitudinal lines; the radial horizontal strips are woven in a full-penetration yarn-threading mode to form horizontal strips which are arranged in parallel, and the vertical and horizontal strips are vertically crossed.
Further, the base fabric layer is formed by weaving 100-10D chemical fiber filaments.
Furthermore, the base fabric layer is made of 12/10// warp flat tissue and is arranged in a mode of opposite pulling with the radial tissue of the pattern layer.
Furthermore, the elastic layer is formed by weaving 100-10D spandex filaments.
Further, the elastic layer is made of 22/00// weft insertion type tissue.
The invention also provides a warp knitting production process of the light and thin breathable sun-blocking fabric, which comprises the steps of raw yarn warping, warp knitting manufacturing, pretreatment, presetting, dyeing, finishing, drying and shaping.
Further, a tricot machine is adopted by the machine for warp knitting and weaving, and the fabric layer passes through four guide bars on the machine: GB1, GB2, GB3, GB4 integration warp knitting form, check card flower layer is woven by two sley bars of GB1 and GB2, base cloth layer, the elasticity layer is woven by GB3, GB4 respectively and is formed.
Furthermore, the yarns are threaded on three guide bars GB2, GB3 and GB4 in a full-penetration manner, and on guide bar GB1 in a one-penetration-three-empty manner.
The invention has the following advantages: the light, thin, breathable and sun-blocking fabric prepared by the invention has good permeability because the whole fabric adopts the warp knitting tissue which is formed by the coils. The check pattern layer gives people a fresh and exquisite feeling, and has good ultraviolet resistance by using the check patterns instead of the through hole tissues; the base cloth layer tissue and the radial tissue of the check pattern layer are arranged in a counter-pulling mode, so that the radial tension is uniformly distributed, the base cloth layer tissue is not easy to deform, and a finished product is stable and does not foam. The elastic layer can make the fabric have large transverse elastic contraction and strong stretching force and restoring force. The prepared fabric is light, thin and breathable, has unique check textures, and is simple, elegant, concise and elegant.

Third, dyeing process
(1) Process formula
(2) Dyeing and finishing process
The mechanism of the textile anti-ultraviolet radiation finishing is to apply a substance which can reflect ultraviolet rays or selectively absorb ultraviolet rays and release the substance harmlessly to the textile. When light irradiates on the fabric, the fabric finished by the ultraviolet radiation prevention can reflect ultraviolet rays harmful to human bodies through the ultraviolet screening agent or selectively absorb the ultraviolet rays and convert the energy of the ultraviolet rays into low energy to be released, so that the effects of preventing sun and protecting skin are achieved.
Dyeing and finishing process: blank → pretreatment → reservation → dyeing → drying and sizing → finished product packaging → finished product warehousing (the parts are not described in detail and are all conventional processes).
Because the ultraviolet-resistant finishing agent is mostly insoluble in water, the ultraviolet-resistant finishing agent and the adhesive are used for one-bath in order to fix the ultraviolet-resistant finishing agent on the surface of the fabric. The padding liquid consists of an anti-ultraviolet finishing agent, an adhesive, a cross-linking agent and a softening agent, and the proportion is as follows:
the width of the finished product is 180cm, and the square gram weight is 68g/m2The fabric is light, thin and breathable, and the moisture permeability is more than or equal to 6000 g/(m)224h), the air permeability is more than or equal to 50 mm/s; UPF value>50. The finished product has unique check texture, is simple and exquisite, and is simple and elegant, as shown in figure 3.
