Abstract
The invention belongs to the technical field of textile production, and relates to a production process of torsion-free plain cloth. The production process comprises the steps of weaving yarns by using a knitting machine to obtain raw fabric, performing alkali shrinkage treatment on the raw fabric, and then performing a subsequent dyeing and finishing process to obtain the finished torsion-free plain cloth. The production process combines the optimized weaving process parameters with the innovative tension-free novel alkali shrinkage treatment technology, so that the produced torsion-free plain cloth reaches an excellent level in tightness. The torsion test result is infinitely close to zero under the preferable parameter setting, the performance of the torsion test result is equivalent to that of the traditional woven fabric, the torsion test result can completely replace the woven fabric with the same thickness, and the torsion test result shows excellent dimensional stability and torsion-free characteristic.
Description
Technical Field
The invention belongs to the technical field of textile production, and relates to a production process of torsion-free plain cloth.
Background
Because of the characteristics of simple structure, uniform texture, easy dyeing and printing, the plain cloth has wide application in daily life. The cloth is an ideal choice for numerous household textiles and garments due to its smooth hand feel, good breathability, and ease of cleaning and maintenance. The production process of knitted plain cloth is simplified and the production speed is fast compared with woven fabric, which makes it have obvious advantages in terms of cost control and quick response to market changes.
In the field of household articles, plain cloth is often used for making bedsheets, pillowcases, tablecloths, curtains and the like. The smooth surface is attractive and elegant, is easy to clean, and is very suitable for the daily frequent use environment. Especially in summer, the plain cloth becomes an ideal material for making bedding by virtue of good air permeability and hygroscopicity, and helps people keep cool and comfortable in hot weather. In the clothing field, plain cloth is very suitable for making T-shirts, underwear, night wear, children clothes and the like due to the characteristics of light weight, thinness and softness. These garments require a comfortable skin-friendly fabric, while plain cloth meets these needs exactly. In addition, the plain cloth can also create colorful patterns and colors through advanced printing and dyeing technologies, thereby meeting the increasing personalized demands of consumers.
Torsion (twist rate, twist or Skew) refers to the twisting or tilting phenomenon that occurs during processing, handling or use of the fabric in a textile. In particular, torque refers to the rotation or deflection of the fabric in one direction relative to the other. This phenomenon can occur in several steps of weaving, dyeing and finishing, printing, sewing, etc., and can affect the appearance and performance of the fabric. Plain cloth is typically joined together by a continuous loop of yarn forming structure that imparts some stretch and elasticity to the cloth. During production, the yarn is passed through a needle to form a continuous loop structure using a knitting machine (e.g., a large circular machine). Because of its structural characteristics, plain cloth, which has not been specially treated, exhibits a tendency to twist, resulting in problems of twisting or rotation of the cloth during processing or wearing, particularly in wet conditions. In contrast, woven fabrics are comprised of vertically interwoven warp and weft yarns, forming a stable planar lattice structure. Because of its structural stability, woven fabrics have little or no torque in most cases, which means that woven fabrics are less prone to distortion during processing and wear, and have better dimensional stability.
For garment manufacturers, if there is a large torque in the plain cloth, the cloth may twist or deform during cutting and sewing, resulting in an asymmetrical or ill-fitting finished garment. In household articles, such as sheets and curtains, if the plain cloth used has torsion problem, after a period of use, the articles may be found to have irregular wrinkles or be unable to be laid flat. High torque muslin also requires extra care in cleaning and ironing, otherwise it may shrink or deform after cleaning, and it takes more time and effort to iron to restore its original appearance.
To overcome these problems, the textile industry is actively developing new technologies, aiming at reducing the torsion problem of the knitted plain cloth and improving the dimensional stability of the knitted plain cloth to better meet the market demand while maintaining the original advantages of the knitted plain cloth.
Disclosure of Invention
The invention provides a production process of torsion-free plain cloth aiming at the problems in the prior art.
One object of the invention is achieved by the following technical scheme:
a torsion-free plain cloth production process comprises the steps of weaving yarns by using a knitting machine to obtain a blank cloth, performing alkali shrinkage treatment on the blank cloth, and then performing a subsequent dyeing and finishing process to obtain a finished torsion-free plain cloth.
Preferably, the knitting machine comprises the following parameters of 30-50 inches in diameter, 30-50G in needle cylinder density and 2500-5000N in total needle count, and the knitting machine is woven in a counterclockwise rotation mode. The diameter of the working cylinder of the knitting machine is 30-50 inches, the number of needles in each inch is 30-50, the more the number of needles is, the finer the knitted fabric is, and the total number of needles in one circle of the knitting machine is 2500-5000.
Further preferably, the knitting machine has a diameter of 30-40 inches, a needle cylinder density of 30-40G, and a total needle count of 2500-3000N.
Preferably, the yarn length of the yarn is 9-11 cm/50N, namely, the yarn length is 9-11 cm under the tension of 50N.
Preferably, the woven weave structure is a weave structure of single-sided plain cloth.
Single jersey is a common knit construction having a simple weave pattern with the primary loops formed by the yarns. A feature of this construction is that the front and back surfaces look the same or similar and are therefore referred to as a single sided construction. Each yarn forms a closed loop through the crochet, the loops being interconnected in the cross-machine direction and the machine direction, forming the basic structure of the fabric. The loops of each row are continuously formed from the same yarn, and the loops of two adjacent rows are interlocked together to form a continuous chain-like structure. The front and back sides of the fabric look very similar and generally exhibit a uniform texture and appearance.
Preferably, after the weaving is finished, singeing treatment is further required on the blank cloth, wherein the temperature of a fire hole in the singeing process is 1100-1200 ℃, and the speed is 80-95 m/min.
Preferably, the alkali shrinkage treatment comprises immersing the raw fabric into an alkaline agent and adding an alkali shrinkage auxiliary agent to perform alkali shrinkage treatment, so that the tensile tension of the raw fabric is 0, and the treatment speed is 10-30 yards/min. During the alkali shrinkage, the cloth is ensured to be sufficiently contacted and uniformly treated in the solution, and is not allowed to be subjected to any stretching during the treatment to avoid dimensional changes.

OWF is a relative unit of measurement and is widely applied to the textile industry, and the mode is convenient for formula standardization, so that the production process is more controllable and repeatable.
Although alkali shrinkage may improve fabric performance, treatment with high concentrations of alkali may result in a decrease in the green strength of the fabric. In order to improve the dimensional stability of the fabric and enable the fabric to achieve the torsion-free characteristic, the alkali shrinkage auxiliary agent with the crosslinking effect is innovatively added in the alkali shrinkage treatment process, so that the dimensional stability and the wrinkle resistance of the fabric can be effectively improved.
