Description

Method for producing viscose twisted silk and modal/cotton interwoven jacquard home textile fabric Technical field

The invention relates to a quilt cover, in particular to a production method of a viscose twisted silk and a modal/cotton interwoven jacquard home textile fabric, belonging to the technical field of textile products.

Background technique

Viscose fiber is soft, moisture-absorbing and breathable. Its gloss, hand and thermal conductivity are close to silk. Therefore, viscose silk has inherent advantages. Due to the low wet strength of the viscose fiber, the elongation is large, and the weaving, dyeing and finishing are difficult. In the existing products, the weft yarn is generally made, and few manufacturers produce the warp viscose filament home textile fabric due to the production process. The difficulty and the technical height requirements in the production process, there are many manufacturers want to try, but the experimental results are not ideal, therefore, there is an urgent need for a new solution to solve the technical problem.

Summary of the invention

The invention aims at the technical problems existing in the prior art, and provides a production method of a viscose twisted silk and a modal/cotton interlaced jacquard home textile fabric, and the technical proposal proposes using a viscose filament as a warp yarn and cooperating with the twisted yarn. And high-density, the development of a silk jacquard home textile fabric to meet the needs of the market.

In order to achieve the above object, the technical solution of the present invention is as follows, a method for producing a viscose twisted silk and a modal/cotton interwoven jacquard home textile fabric, characterized in that the method comprises the following steps: fabric specification: 1220 cores/10 cm , weft density 413 roots/10cm, width 269.5cm, large jacquard tissue.

(1) Preparation of raw materials: the warp yarn is selected from viscose continuous spinning 75D/30f twisted yarn with a twist of 650捻/m, and the weft yarn is made of modal/cotton siro-spun 40s yarn. The process is short and the fabric is made. Silky luster and super soft hand; when the twist is lower than a certain value, the viscose filament is too soft, the head rate is high during the warping and weaving process, the production efficiency is low, and the fabric loses elegance after finishing. Gloss, when the twist is higher than a certain value, the viscose filament is hard and difficult to form. At the same time, the twist is too high, the production efficiency is low, and the fabric is not smooth and supple.

(2) Stripping warping: 1) First calculate the total number of roots, the number of warping is 58*556+1*492; the width of strips is 47.38mm*58+41.93mm*1; the displacement is 0.91mm 2) Do a good job of cleaning. Before the production, do the cleaning work of each static eliminator, each cymbal and each guide roller. Secondly, the warping tension is the key of each road. The tension should be detected step by step. The finishing dye colors are inconsistent. 3) Adjust the tension, the tension of the creel is 5.0-6.5CN, The take-up tension is 14kg; 4) warping length, due to the characteristics of the raw material, the warping length should not be too long, and must be inverted into a weaving shaft within a certain period of time to reduce the beading phenomenon between the strip and the strip. 5) Precautions and solutions. When the warping process is in the braking state, the viscose filament is prone to residual torque due to the drafting before the tension disc. The twisted wire loop is easy to be used in the sizing and the parallel shaft. Causes fleas and hangs, causing uneven tension of the monofilament, increasing the number of knots and downtime, affecting the quality of warping. In order to solve this problem, the tension of the tension disc can be appropriately increased, preferably 5.0-6.5CN. In addition, a cloth sleeve can be placed outside the raw material package to control the balloon tension. This will solve the kinking problem and meet the production requirements.

(3) Flower pattern and tissue design: the flower pattern is mainly elegant and delicate European pattern, with a flower width of 78cm and a length of 125cm. In order to reflect the silky style of the fabric, the ground tissue is double weft, and the table organization is five three flying. Through the surface satin, the organization is ten three-flying satin satin; the flower-shaped leaves use eight three-fly-one reinforcement, two reinforcement, and three reinforcement weft satin from the outer layer to the inner layer, thus forming a layer from light to dark. Sense; the flower part adopts ten seven-fly-one reinforcement, two reinforcement, three-enhanced weft satin, and ten or twelve twill on the flower core. When adopting a step-by-step organization, the organization has the same starting point and the organization has no long floating lines. The entire fabric highlights the combination of classic and modern. The fabric structure is shown in Figure 1. In the figure, the vertical line indicates the warp yarn, the horizontal line indicates the weft yarn, and the warp yarn and the weft yarn are interwoven to form a large jacquard fabric. In the figure, the floating point is indicated by “■”, and the lower floating point is represented by “□”. The different jacquard tissues in the fabric are expressed by the change of the upper and lower floating point numbers.

(4) Weaving: Weaving with Summet rapier ALPHA-340, when the temperature of the workshop is controlled at 23 °C ~ 27 °C, the relative humidity is 68% ~ 74%, the efficiency of the loom and the quality of the fabric are stable, and strict control is required. Workshop temperature and humidity, followed by weaving process: back beam height 0mm, opening time 330 degrees, sword time 68 degrees, sword time 180 degrees. This variety is produced on the large jacquard weaving machine of ALPHA-340. During the weaving process, the single fiber is fine, and the warp is easy to be broken and the weaving efficiency is affected. Therefore, it is necessary to appropriately reduce the tension of the upper machine, increase the height of the shed, and ensure that the opening is clear. For the weft yarn to reduce the desorption tension, choose the appropriate storage weft form. Due to the large weft shrinkage of the fabric, auxiliary equipment such as web support and matte rubber should be selected to ensure smooth weaving.

Technical requirements during the weaving process:

1) Due to the high density of the product, the latitudinal shrinkage rate is large, which increases the load on the web and the matte rubber of the coiling system, and is prone to weft and smearing. To do this, always replace the matte rubber to ensure the friction required for winding. At the same time, the needle roller is changed into three rows of coarse toothed support, and the effect is good.

2) When the filament appears in the warp, it should be treated and exchanged in time to prevent large-area warp yarns from being broken. When operating, it is necessary to prevent the warp and weft yarn from being scratched.

3) The tension on the machine when weaving is: 2000N, the rotation speed is 250r/min.

4) Control of temperature and humidity in the workshop. If the relative humidity is too small, the workshop is dry, and the yarn is easily raised by the friction of the steel file, the heald, and the dropper, and the yarn is easily entangled, which affects the clearing of the opening. When the humidity is too high, the viscosity of the viscose filaments is too large, resulting in a strong decrease. According to the actual production situation, the temperature of the workshop is controlled at 23 ° C ~ 27 ° C, the relative humidity is 68% ~ 74%, the efficiency of the loom and the quality of the fabric are both More stable.

(5) Finishing: The fabric is dyed by flat-bath one-bath method, using reactive dyes, and all parts of dyeing should pay attention to prevent wrinkles, especially the setting process. The process is as follows: grey fabric tumbling → singeing → scouring → pre-formed → dyeing → Washing and drying → Finishing → Finished product;

1) Singeing: The speed of singeing is slow, although it is conducive to the singeing clean, but it is easy to cause the semi-finished product to feel hard and increase the weight, so it is necessary to control the appropriate conditions;

2) scouring: cleaning various oils and dirt added and accumulated in the fabric during processing;

3) Predetermined type: control a process condition that satisfies the requirements of removing wrinkles, improving elasticity and stabilizing the width of the door, and lowering the setting temperature as much as possible, avoiding the predetermined shape to make the fabric feel harder;

4) Dyeing: The one-bath reactive dye is used to dye viscose, modal and cotton. Although the three raw materials belong to the same nature, the color ratio will be different, so that the fabric with similar yarn-dyed effect can be realized. ;

5) Washing and drying: removing excess and unreacted dye on the fabric to improve the color fastness of the fabric;

6) Finishing: pre-shrinking, calendering, tentering and shaping.

Compared with the prior art, the advantages of the present invention are as follows: 1) The entire technical scheme of the present invention is ingeniously designed. The large jacquard home textile fabric is interwoven by warp and weft yarns, and the warp yarns are interlaced across the weft yarns at right angles, and the warp yarns are continuously spun 75D. /30f twisted wire, twisting degree is 650捻/m, weft yarn is made of modal/cotton blended 40s yarn; 2) The viscose simulation silk jacquard home textile fabric developed by this technical scheme is soft and smooth, shiny like silk, better reflecting fabric Silky style, with excellent hygroscopicity, breathability and other performances, combining practicality, comfort and beauty, satisfying people's pursuit of high-grade and high quality of home textile fabrics; 3) the entire production process It is not complicated, easy to operate, and easy to promote and apply on a large scale.
