PROCESS CONTROL IN COMBER

In combers, the important aspects to be controlled are waste level, combing efficiency and sliver irregularity. Mills generally fix the amount of comber waste to be extracted only by past experience and not on the fiber length distribution of the cottons processed which primarily determines the amount of waste to be removed to achieve the desired fiber length uniformity. Best results of combing of Indian cottons are generally achieved by suitable adjustments of detaching distance, even though the top comb penetration is not very deep. However, the cottons have a high fiber length uniformity but the lap contains too many impurities and neps, a deep penetration of top comb is desirable, without fiber rupture. Mill process all classes of cottons in the same comber without regard to the suitability of the needling arrangement. Coarsening of the needling scheme helps to reduce the comber waste by 2% for coarser cottons and by 1% for finer cottons. Incase of heavier laps, it increases th...

Types of Fabric and Their Uses in our life

Image
Types of Fabric and Their Uses   Fabric Types: In today’s modern textile sector, various types of fabric produced for woven, knit and non-woven fabric. This article has presented the total classification of fabric for woven, knit and non-woven. Classification of Fabric: There are mainly three types of fabric, which are in the below: Woven fabric , Knit or knitted fabric, Non-woven fabric. All the above fabrics have explained in the following: Woven fabric: The fabrics which are produced by interlacing two sets of yarn i.e. war yarn and weft yarn by in is termed as woven fabric. Woven fabric Types of Woven Fabric: There are various types of woven fabrics produced in textile weaving sector which are mentioned in the following: Poplin fabric or broad cloth, Denim fabric, Pinpoint oxford fabric, Corduroy fabric, Chambray fabric, Crepe fabric, Oxford fabric, Melange fabric, Flannel fabric, Royal oxford cloth, Dobby...

Knitting Machine Classification

Image
Introduction of Knitting Machines | Classification of Knitting Machines Knitting Machines: Knitting is the method of creating fabric by transforming continuous strands of yarn into a series of interlocking loops, each raw of such loops hanging from the one immediately preceding it. It is the most common method of interloping and is second only to weaving as method of manufacturing textile products. Knitted fabric can be produced by hand or machines. We can denote knitting machine as it is a machine can convert one or one set of yarn into loop structured fabric by the mechanical movement of it basic elements. The main basic elements of knitting machine are needle, sinker and cam. The machines used for the manufacturing of knit fabrics can be divided into machines with individually driven needles and needle bar machines. The former type of machine incorporates needles which are moved individually by cams acting on the needle butt; they are used for producing w...

Knitting- Intro

Introduction to Knitting Hand and machine knitted fabric is created by interlocking a series of loops. The loops (stitches) are interlocked using a needle to hold the existing loop while a new loop is formed in front of the old loop. The old loop is then brought over the new loop to form the fabric.  Knitting differs from weaving in that a single piece of yarn can be used to create fabric.  The fabric consists of horizontal rows known as  courses  and vertical columns of loops known as  wales . Knitted fabric has useful properties that make it suitable for a range of garments including tights, gloves, underwear and other close-fitting garments.  The loop structure of knitted fabric stretches and molds to fit body shapes.  The air trapped by the loops keeps the wearer warm. Fashioning, loops and ladders When knitting, increasing or decreasing the number of stitches in a row widens or narrows the...

CLASSIFICATION OF YARN FAULTS

Assessment of Classimat faults  in classimat tester : Due to the existence of fewer faults and nature of distribution of these faults, it is recommended to take randomly at least 5 tests of each 100km of yarn. The testing yarn has to be carried out on a winder having a uniform winding speed. Once the testing is over, the results are in the form of printout. And it contains two sets of data, the one is Individual faults & other one is cumulative faults / 100km of yarn. And the major causes of the Classimat faults are tabulated below : SHORT THICK FAULTS :            A4 -High Ring frame speed -Loose (or) Spun in fly -Foreign matter -Type of spacers          B4 -High Ring frame speed -Loose (or) Spun fly -Floating fibers -Narrow cage length and tight cage length              ...
