Bed fabrics generally have the characteristics of skin-friendly, soft, and moderately thick, and require fabrics to have certain standards and grades for pilling, breaking strength, color fastness, and shrinkage. At present, most of the bedding fabrics on the market are produced by the weaving method, and the common structure is plain weave, twill, satin and the like. With the improvement of the softness, comfort and skin-friendly requirements of bedding fabrics, knitted fabrics have gradually emerged on the market with their unique softness and comfort.
Weft knitted bed fabric development
The weft knitting production process is generally the original yarn - winding - weaving - dyeing and finishing - finished products. The characteristics of weft knitting technology are the diversity of raw materials, such as spun yarn, filament yarn and elastic yarn. Secondly, the equipment is small, the production process is short, the proofing is convenient, the production flexibility is high, and the third is fabric extension. Good, soft and comfortable.
When producing weft-knitted fabrics, the width of the fabric should match the size of the bed. As the width of the bed continues to increase, the weft knit width for the bedding fabric should be increased to about 2.5 m. Conventional weft knitting machines have a diameter of 30" and 34", so it is necessary to vigorously develop wide-width production technology.
Fabric sizes for weft-knitted fabrics require a certain degree of stability. The weft knitted fabric has obvious fluctuations in the size of the weaving process, the shaping process and the use process. How to stabilize the fabric size is a difficult problem to overcome. In the actual development process, the size of the final bedding product can be stabilized within a certain range from the aspects of raw materials, fabric structure, setting method and equipment, and shrinkage rate.
Warp knitted fabric development
The warp knitting production process is generally the original yarn - warping - weaving - dyeing and finishing - finished products. Warp knitting technology has many advantages. First of all, the warp knitting machine can choose a wide range, generally between 330 and 553cm, which can meet the needs of wide width, and the increase of the width has little effect on the production speed. Secondly, the output is higher, if the machine speed is 2000r In the calculation of /min, about 1 m of cloth can be produced per minute; in addition, the coil structure is made to have a slightly larger thickness than the woven fabric, and has good drapability, flexibility, and certain elongation.
Because the warp knitting machine has poor adaptability to raw materials, generally only 40-100D chemical fiber filaments can be used. In the process of actual warp knitting and development of bedding fabrics, appropriate processing measures need to be taken. For example, the use of spun yarns with higher yarn counts, uniform strips, less hairiness and high strength; pre-treatment of yarns, reinforcement of cohesion between fibers, improvement of yarn wear resistance, reduction of flying flowers; reduction of machine speed It is 70%-80% of the production speed of conventional chemical fiber; it is used to clean the machine for timing; the yarn guide parts of the warp knitting machine are improved to reduce the peak tension of the yarn and reduce the friction on the yarn.
Development example of knitted bedding fabric
Knitted plain bedding fabrics are generally made of cotton T-shirt fabrics that are often worn in the summer. Their breathability, fit, comfort and sweat absorption are unmatched by traditional home textile fabrics. It overcomes the shortcomings of traditional woven plain weave fabrics that are too thin, twill fabrics are rough, and satin fabrics are damp and cool. Another advantage is that the quilt cover can be directly covered in summer, which is suitable for a healthy and fashionable bare sleep mode.
Compared with traditional textiles, knitted sanded fabrics have the advantages of soft hand feeling, close fit and strong warmth. Especially in the cold winter, the moment of contact with the skin, there is no slight cold feeling, which is especially suitable for people who are afraid of cold. At the same time, it has the characteristics of environmental protection and convenient washing. The most important thing is that weft-knitted fabrics can be used close to the body and are increasingly popular in European and American families.
Knitted jacquard bedding fabrics generally adopt transfer structure, twisted tissue, double-sided jacquard structure and the like. The transfer structure can form a three-dimensional pattern of twisted flowers, and can also form a pattern of hollowing effect; the twisted tissue gives the fabric a strong retro atmosphere. The hollowed out tissue can form patterns such as fold lines, diamonds, and wavy shapes, adding a vibrant color to the fabric. Jacquard fabrics can be used to produce colorful pillows and pillowcases, or they can be embellished with continuous small florals on the edges of the sheets or quilts.
