Description

Technical Field

[0001] The invention relates to the technical field of knitted fabrics, in particular to a soft, wrinkle-resistant knitted fabric and a process thereof. Background Art

[0002] Knitted fabrics are fabrics formed by bending yarns into loops and interlacing them with knitting needles. They are divided into warp knitted fabrics and weft knitted fabrics based on the knitting method and direction. Knitted fabrics are soft, breathable, sweat-wicking and warm, and most of them have excellent elasticity and extensibility. Compared with woven fabrics, they have high production and are suitable for small batch production. Knitted clothing is comfortable to wear, fits the body, has no tightness, and can fully reflect the curves of the human body.

[0003] However, traditional knitted fabrics have a problem of being too flexible when used as clothing. Many people must have had this experience. Knitted clothing such as sweaters are very soft and comfortable to wear, and it is difficult to have large wrinkles. However, knitted fabrics give people a feeling of being very thick and very absorbent. After washing the fabric, it will absorb water and become very heavy. After being hung to dry, the moisture will dissipate and some areas of the clothes, especially the hanging parts, will feel loose, which is commonly known as "thank you". Wrinkles are mainly divided into two categories: regular wrinkles and irregular wrinkles. The above-mentioned local wrinkles are a type of irregular wrinkles. There are two main reasons: 1. Knitted fabrics are generally woven by warp knitted fabrics and weft knitted fabrics, which are divided into warp knitted threads and weft knitted threads in the horizontal and vertical directions. Generally, warp knitted threads and weft knitted threads use different materials or different knitting lines and weaving methods. After absorbing water and swelling, the knitted fabrics as a whole absorb water and swell. On the one hand, there is a difference in the amount of water absorbed by the warp and weft threads. After drying, the water dissipates. On the other hand, there is a difference in the amount of expansion between the warp and weft threads after drying. This may lead to the situation that the warp threads are completely restored but the weft threads are not completely restored. The incompletely restored warp and weft threads will pull the restored warp threads in the vertical direction, thereby causing local wrinkles; 2. Since knitted fabrics are too flexible and lack rigidity, when they are hung with weight after absorbing water, the gravity acting on the hanging area is very strong, which can easily lead to excessive stretching. Once the stretching limit is reached, irreversible deformation will occur. Therefore, the elastic strength or deformation of knitted fabrics still needs to be improved.

[0004] In view of the above problems, it is urgent to carry out innovative design based on the original soft wrinkle-proof knitted fabric and its process. Summary of the invention

[0005] The technical solution of the present invention aims at the technical problem that the existing technical solutions are too single, and provides a solution that is significantly different from the existing technologies. Specifically, the purpose of the present invention is to provide a soft and wrinkle-resistant knitted fabric and a process thereof, so as to solve the problem proposed in the above-mentioned background technology that general warp knitted yarns and weft knitted yarns are made of different materials or different knitting lines and weaving methods. After absorbing water and swelling, the knitted fabric as a whole absorbs water and swells. On the one hand, there is a difference in the amount of water absorbed by the warp and weft threads, and after drying, the moisture dissipates. On the other hand, there is also a difference in the amount of expansion between the warp and weft threads after drying. This may lead to the situation that the warp threads are completely restored but the weft threads are not completely restored. The incompletely restored warp and weft threads will exert a vertical pulling effect on the restored warp threads, thereby causing the problem of local wrinkles.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a soft and wrinkle-resistant knitted fabric, comprising warp knitted yarn and weft knitted yarn, the basic knitted fabric is formed by a plurality of warp knitted yarns and a plurality of weft knitted yarns using a fish scale cloth knitting process, and the warp knitted yarn is formed by a warp knitted glass fiber and a warp knitted nylon fiber using a spiral flower weaving process, and the weft knitted yarn is formed by a weft knitted glass fiber and a weft knitted nylon fiber using a spiral flower weaving process.

[0007] Preferably, the combination of the warp knitted yarn and the weft knitted yarn is in the shape of fish scales, and the warp knitted yarn and the weft knitted yarn are made of the same material and have the same fineness, and both the warp knitted yarn and the weft knitted yarn are wavy.

[0008] Preferably, the warp-knitted glass fiber is wavy, and the wavy convex points of the warp-knitted glass fiber reduce the spiral weaving frequency by - millimeter at every interval to form equidistant weaving loose points, and the weaving loose points spaced one unit apart in the warp and weft directions are interlocked with each other.

[0009] Preferably, the weft-knitted glass fiber is wavy, and the wavy convex points of the weft-knitted glass fiber reduce the spiral weaving frequency by - millimeter to form equidistant weaving loose points, and the weaving loose points spaced one unit apart in the warp and weft directions are interlocked with each other.

[0010] A process for making soft and wrinkle-resistant knitted fabrics, comprising the following steps: S1: Weaving warp knitting yarn and weft knitting yarn unit, firstly, the warp knitting glass fiber and the weft knitting glass fiber are subjected to serpentine bending and heat setting treatment, so as to obtain relatively stable serpentine warp knitting glass fiber and weft knitting glass fiber, which have relatively excellent rigidity, tensile strength, elastic strength, low water absorption and heat resistance; S2: Use traditional spiral weaving to tightly wrap the warp knitted cotton fiber around the outside of the serpentine warp knitted glass fiber, and reserve loose winding points at a fixed distance. Based on the requirements of fabric production, wrap 2-4 fewer turns or 3-5 mm apart at a specific position to make the fiber arrangement in this area vacant. Similarly, use the above method to process weft knitted glass fiber; S3: On the basis of step S, strictly control the warp knitted yarn and weft knitted yarn after forming to ensure the same material and unit mass, weave the fabric after tightening, compacting and softening, so that the warp knitted yarn and the weft knitted yarn are interlocked with each other at the sparse weaving points with a unit interval in the warp and weft directions, so as to produce the required basic fabric. Finally, different weaving processes and pattern printing processes can be used to enrich the basic fabric according to needs.

[0011] Compared with the prior art, the present invention has the following beneficial effects: The present invention adopts warp knitted glass fiber and weft knitted glass fiber with rigidity, flexibility, low water absorption, high tensile elastic strength, low water absorption and high heat resistance as the main core of the warp and weft unit lines (warp knitted yarn and weft knitted yarn are hereinafter referred to as warp and weft unit lines), and weaves relatively soft warp knitted nylon fiber and weft knitted nylon fiber on the outside, so that each warp and weft unit line has both the properties of nylon fiber and the characteristics of glass fiber, greatly reduces the water absorption rate of the warp and weft unit lines, weakens the unit water absorption of the fabric to reduce the difference in the scaling of the warp and weft lines; In addition, traditional knitted fabrics are stacked on each other, and the mutual influence between the warp and weft unit lines is relatively small. Although each warp and weft unit line has a certain elastic tensile strength in its own warp and weft directions, when wrinkles occur, the warp and weft lines in the wrinkle area will be subjected to forces different from their own expansion and contraction directions. Simply put, the arrangement of the warp and weft lines will be disrupted and cannot be effectively reset. The warp and weft unit lines in the fabric of this scheme adopt a fishnet design with staggered hooks. The adjacent warp and weft unit lines influence, restrict and constrain each other. After being subjected to external force, multiple warp and weft unit lines will be dispersed from multiple scattered units into a whole, and the whole will resist external force, thereby effectively alleviating local wrinkles.

[0012] At the same time, a special knitting process is used to reserve winding sparse points between the warp and weft unit lines in the serpentine arrangement, so that the warp and weft unit lines can bite each other at the weaving sparse points with a unit interval in the warp and weft directions. When the warp and weft unit lines arranged in a serpentine arrangement are subjected to tension, the serpentine warp and weft unit lines will first be deformed into a straight line and then use their own elastic expansion and contraction, thereby increasing the deformation interval from serpentine to straight line, and further improving the tensile and wrinkle resistance of the warp and weft lines; at the same time, the overlapping contact points between the warp and weft lines form a mutually interlocking posture, which on the one hand reduces the thickness of the stacked warp and weft unit lines, and on the other hand, the warp and weft lines bite each other, and the degree of integration between the warp and weft lines is high, which not only has a higher dislocation stability, but also makes the fabric surface smoother, and the warp and weft unit lines have the function of mutual limitation and restraint, thereby improving the anti-dislocation ability between the warp and weft lines, and the warp and weft unit lines are made of the same material and posture design, which ensures that the warp and weft unit lines have the same scaling amount.
