Description
[ technical field ] A method for producing a semiconductor device
The invention relates to a spun silk knitted fabric capable of being printed and having a specific square meter gram weight, and particularly relates to 200-220 g/m2The spun silk knitted fabric can be used as an underwear fabric and can also be used as an externally worn garment fabric.
[ background of the invention ]
Along with the increasing living standard of people, the natural fiber fabric with excellent wearing characteristics, especially the mulberry silk and spun silk fabric, is popular with people in spring, summer and autumn. In hot summer, the mulberry silk or spun silk clothes become high-grade consumer goods for people. Mulberry silk and spun silk belong to natural protein fibers, have good water absorption, are soft and comfortable, have health care effect on skin, have the reputation of fiber queen and are called artificial skin. Generally, silk fabric products are mostly woven by tatting, and fabrics woven by interweaving warps and wefts of silk tatting fabrics are not good in elasticity, air permeability and wearing comfort, so that silk knitted fabrics are developed vigorously in recent years and are popular in the market.
Compared with spun silk knitted fabrics, the mulberry silk knitted fabrics are too soft in hand feeling and too close to the skin, and are used for making underwear for a long time; the spun silk knitted fabric is good in stiffness and smoothness, is cheaper than mulberry silk, can be used as underwear and garment (front) wear, has all the excellent performances of mulberry silk knitted fabric, is elegant and moist in gloss, is stiff and smooth, is breathable, and floats and is also capable of being used as a printed spun silk knitted fabric with excellent quality. After the fabric is printed, the design and color of the fabric are various, and the fabric is very suitable for making high-grade printed spun silk skirts of inner and outer coats.
The design gram weight is 200-220 g/M2The single-side plain spun silk knitted fabric is obtained by weaving on a 24G single-side circular knitting machine in a conventional production process, single incoming yarn is used for incoming yarn, and the yarn count specification of the knitted fabric is 55N/2-65N/2. As is well known, the grammage is 200 to 220g/m2The fabric has the advantages that: the hand feeling is moderate in softness and hardness, and the weight is moderate without losing stiffness and smoothness, so that the underwear can be made, and the underwear can be further made into outer clothes for wearing. However, the doubled yarn formed by spinning spun silk has strong elasticity and high hardness, is poor in bending and torsion deformability when directly used for knitting, is not easy to form uniform coils, is easy to fall off and generate holes to cause weaving defects when being knitted, and is easy to generate weaving defects when being knitted by a single yarn, so that the defects of overlarge knots and poor cloth surface flatness exist.
[ summary of the invention ]
The invention aims to provide 200g/m with uniform knitting loop, small knots, few defects, high cloth surface flatness and good moisture absorption2～220g/m2Spun silk knitted fabric.
Therefore, the technical scheme of the invention is as follows:
200g/m2～220g/m2spun silk knitted fabric is produced by weaving raw cloth with barrel-packed spun silk plied yarn on a circular knitting machine and refining the raw cloth into a spun silk knitted fabric with a gram weight and a longitudinal and transverse density of 200-220G/M262 meshes/5 cm and 82 meshes/5 cm as inner and outer garment fabrics capable of being printed, and the spun silk yarn specification and the coil form of the spun silk knitted fabric are 120N/2 spun silk yarn and double-yarn-in double-yarn knitted double yarns respectivelyThe stitch is a single-side plain weave, and the wound spun silk plied yarn is directly woven on an 18G single-side circular knitting machine under the condition that 22# knitting emulsified oil is adsorbed during medium withdrawal.
The raw grey cloth is obtained by an 18G single-face circular knitting machine under the conditions that the incoming yarn tension is 4-5 CN, the yarn conveying length of a yarn conveying disc is 16.5cm/50 needles, the number of knitting paths is 42, and the winding speed of the raw grey cloth is 20 mm/rotation.
Compared with the prior art, the invention has the following advantages and beneficial effects:
1. the gram weight and the longitudinal and transverse densities are respectively 200-220G/M2The invention is 200-220 g/m with 62 mesh/5 cm and 82 mesh/5 cm2The spun silk knitted fabric adopts 120N/2 spun silk compound yarns and double coils, has the advantages of few defects, small knots and high cloth surface flatness, has better hygroscopicity and better stiffness, and can slow down the elasticity of a colloidal layer on the surface layer of a spun silk raw material, increase the softness of silk threads, relieve the bending and torsional deformation of the spun silk, form uniform coils, reduce the silk thread sleeve falling and the weaving defects of the fabric surface of a braided fabric when the spun silk threads adsorbed with No. 22 knitting emulsified oil are woven, thereby being beneficial to the improvement of the subsequent printing quality.
2. The tension of the incoming yarn is optimized, for example, the missed stitches can be generated when the tension is too low, and for example, the broken holes can be generated when the tension is too high; after the number of weaving paths is reasonably determined, the length of the wire conveying disc with optimized design is reasonably matched with the winding speed of the green body cloth, so that the phenomenon of hole breaking caused by overhigh winding speed of the green body cloth is avoided, and the hole breaking caused by sparse path and thread sleeve removal of the green body cloth due to overlow winding speed is avoided.
