This lab report summarizes the student's study of straight knife and round knife cutting machines. The straight knife machine uses a straight blade to cut large pieces and curves, while the round knife machine uses a round blade and is better for small-scale cutting and gentle curves. Key differences are that the straight knife can cut fabrics from any angle, has higher productivity, but requires more skill, while the round knife is easier to use but can only cut at 90 degree angles. Both machines require regular blade sharpening and cleaning to maintain optimal performance.

KNITTING - Rib structure

PSG college of technology

Rib structure is the second family of knit structures where wales of face stitches and back stitches are knitted alternatively on each side of the fabric. Rib fabrics are produced on machines with two sets of offset needles. The 1x1 rib structure has perfectly balanced stitches with high elastic recovery in the width direction. The 2x2 rib structure has 2 technical face loops and 2 back loops per repeat, making it popular for cuffs and waistbands. Rib fabrics have the same appearance on both sides with moderate lengthwise and very high widthwise extensibility, thickness, and no tendency to curl.

Durable press finish

Prateek Nigam

Durable press finishing provides fabrics with crease retention and freedom from ironing after washing through the use of cross-linking resins. The process involves padding the fabric with a resin like DMDHEU, making the fabric into garments, and curing them at a high temperature to set the creases. This provides better crease retention than wash and wear finishes. The resin must cure at high heat without discoloring and remain fast after washing. However, durable press finishing can reduce fabric strength and abrasion resistance due to the high resin levels and prolonged curing, so softeners are added to minimize these issues.

The tappet shedding mechanism uses tappets attached to a bottom shaft to raise and lower heald shafts, forming a shed for the shuttle to pass through. There are two main types - negative tappet shedding, where the tappet controls only one movement of the heald shaft and an external device returns it, and positive tappet shedding where the tappet controls both upward and downward movement. The tappet rotates and strikes a bowl connected to a treadle lever, moving the heald shaft up or down depending on the type of tappet shedding. Tappet shedding can produce basic weaves but is limited in complexity compared to other shedding mechanisms.

Md Rakibul Hassan

This lab report describes experiments conducted to study the solubility and chemical testing of fibers. Microscopic testing allows reliable fiber identification by examining the fibers' cross-sectional and longitudinal views. The burning test observes each fiber's behavior when ignited, such as smell, residue, or how it approaches the flame. Solubility testing involves placing fibers in solvents at certain temperatures; each fiber will dissolve or not dissolve depending on the solvent, allowing identification. Common fibers can be identified through their solubility in particular chemicals, such as cotton dissolving in sulfuric acid or nylon dissolving in hydrochloric acid. The knowledge of fiber identification is important for properly labeling and caring for textile products.

Study on Identification of Fibres by Burning Test | Burning Test of Fibre

Md Rakibul Hassan

This lab report summarizes an experiment on identifying fibers through burning tests. Key findings include: 1. Different fibers burn with distinct characteristics - cotton burns steadily like leaves, linen is brittle, silk smells like burning hair, wool is difficult to ignite. 2. Synthetic fibers like acetate, acrylic, nylon and polyester melt and burn at the same time, leaving hard ashes with distinctive smells. 3. Rayon burns rapidly like burning leaves. Limitations are that some fibers have similar reactions, requiring caution in identification.

Let-off Motion | Weaving Technology

Md Rakibul Hassan

This document discusses let-off motion in weaving, which controls the tension of the warp yarn by feeding it at a controlled rate. It describes negative let-off, where the warp is pulled against friction, and positive let-off, where the warp beam is rotated to maintain tension. Negative let-off uses weights on a lever system to adjust as the beam radius decreases and maintain a constant tension. Positive let-off systems use a floating backrest and pulley system to sense tension and adjust the feed rate accordingly.

Md Rakibul Hassan

This document discusses knitting technology and the features of V-bed flat knitting machines. It describes two types of knitwear production: cut and sewing, and fully fashioned. Fully fashioned knitwear shapes portions of the garment during knitting by increasing or decreasing loops along the selvedges. A V-bed flat knitting machine has two stationary needle beds and uses latch needles. Different fabrics like single jersey, ribbing, and cardigan stitches can be produced by activating different needle bed cams. Shaping is done through widening by adding needles or narrowing by removing needles to transfer loops.

Picking Mechanism | Beat Up Mechanism | Over Picking Under Picking Mechanism

Md Rakibul Hassan

The document discusses weaving technology and describes different mechanisms involved. It focuses on picking and beat-up mechanisms. Picking inserts the weft thread through the warp shed and can be bidirectional or unidirectional. Beat-up drives the inserted weft to the fell of the cloth. There are different types of picking (over, under) and beat-up (single, double, cam) mechanisms that are suited to different fabric weights and loom styles. Faults like early/late picking and factors influencing beat-up force are also covered.
