Characteristics of woven fabrics
1. The main feature of woven fabric is that the fabric surface is divided into warp and weft. When the warp and weft raw materials, yarn count and density of the fabric are different, the fabric will show anisotropy, and different interweaving rules and finishing conditions can form different appearance styles. The use of woven fabrics in clothing is in a leading position in variety and production quantity, while the clothing made of woven fabrics is very different in processing flow and technological means because of its differences in style, technology and style.
Second, the main advantage of woven fabric is that its structure is relatively stable, its surface is very flat, and it generally does not sag when hanging, so it can be applied to various cutting methods.
Woven fabrics are also suitable for various printing, dyeing and finishing methods. Generally speaking, printed and jacquard woven fabrics are more delicate than knitted fabrics, knitted fabrics and felt fabrics. Woven fabrics have good washability and can be refurbished, dry-cleaned and finished. Inspection of woven fabrics
(A) the production process of woven clothing
Factory inspection of flour accessories → technical preparation → cutting → sewing → keyhole nails → ironing → clothing inspection → packaging → warehousing or shipment.
After the fabric enters the factory, the quantity should be counted and the appearance and internal quality should be tested. Only when it meets the production requirements can it be put into use. Before mass production, technical preparations should be made, including the formulation of process list and sample clothes, and the sample clothes can not enter the next production process until they are confirmed by customers. Fabric is cut and sewn into semi-finished products. After some woven fabrics are made into semi-finished products, according to special technological requirements, post-finishing processing must be carried out, such as clothing washing, clothing sand washing, wrinkle effect treatment and so on. Finally, it is packaged and put into storage after passing the inspection.
(B) the purpose and requirements of fabric inspection
Controlling fabric quality is an important part of controlling finished product quality. By checking the sum of incoming fabrics, the rate of genuine clothing can be effectively improved.
Fabric inspection includes appearance quality and internal quality. Externally, we mainly investigate whether the fabric is damaged, dyed, weaving defects, color difference, etc. Sand washed fabrics should also pay attention to whether there are sand washing defects such as sand marks, dead pleats and splits. Defects that affect the appearance should be marked during inspection and avoided during cutting. The inherent quality of fabric mainly includes shrinkage, color fastness and gram weight (mm, oz). When sampling, representative samples of different varieties and colors produced by different manufacturers should be cut for inspection to ensure the accuracy of the data.
Different dyeing and finishing methods of woven fabrics
Generally speaking, there are two ways of dyeing and finishing woven fabrics, one is dyeing, and the other is yarn-dyed.
Dyeing refers to weaving the grey cloth first, then sending it to the dyeing factory, and after desizing, singeing, scouring, mercerizing, (sanding) dyeing, setting, preshrinking, softening and other processes, colored cloth is obtained. Most printing processes are the same, mainly changing the dyeing process to printing.
Dyeing can also be divided into continuous dyeing and vat dyeing.
Yarn-dyed refers to dyeing the yarn first, then warping, sizing, weaving and finishing to get the finished cloth. Yarn-dyed fabrics are mainly plaid and striped.
I believe that after reading the above introduction, you have a certain understanding of woven fabrics. Woven fabric is a kind of fabric woven by shuttle loom. It has a variety of colors, which is more comfortable to wear as a material and can be more beautiful as a living room curtain.
