Mat

A textile floorcovering of predetermined shape and limited dimensions.

Mat

A modification of plain weave in which two or more ends and picks weave as one, or a fabric made in such a weave. The basic hopsack weaves may be modified in various ways, e.g., by introducing additional interlacing to give firmer cloth (stitched hopsack), or by arranging small square blocks of figures to form diagonal lines in the fabric (twilled hopsack).

Matching

1. A process by which the amount of each colouring matter present in a material is actjusted so that the final colour resembles that of a given sample as closely as possible.
2. A comparison of dyed samples of textiles of nominally the same colour.
Note: 1 and 2 can be done by eye or by using instruments that measure chromaticity co-ordinates.

Matchings

Wool that has been sorted.

Matelass'e

A double or compound fabric with a quilted appearance. It is commonly made with two warps and two wefts, the threads generally being arranged two face, one back in both warp and weft, but other proportions are often used. The quilted effect may be accentuated by the use of wadding threads and a tightly bound ground weave. The designs are formed by floating threads or patches of fancy weaves.

Matelassé

A soft double or compound fancy-woven fabric with a quilted appearance. Heavier types are used as draperies and upholsteries. Crepe matelassé is used for dresses wraps and other apparel. Matelassé is usually woven on a Jacquard loom.

Material Balance

A mathematical representation of material flow through a reaction system. The input material is accounted for throughout its various transformations.

Matrix Fiber

1. A manufactured fiber that is essentially a physical combination or mixture of two or more chemically distinct constituents or components combined at or prior to the time of extrusion (i.e. produced in fiber form) which components if separately extruded would each fall within different definitions of textile fiber. (FTC definition). Matrix fibril fibers have the fibril constituent randomly arranged across the cross section of the matrix. When the fibril component is in high concentration it may actually form a fibrillar network in the matrix. 2. In aerospace textiles a thermoplastic fiber used with reinforcing fiber to form a composite after consolidation with heat and pressure. 3. In nonwovens manufacture fibers that are blended with low-melt fibers to form a thermally bonded fabric.

Matrix-fibril bicomponent fibre

In this type, fine fibrils of one component are embedded in a matrix of the other. The individual fibrils are randomly distributed over the fibre cross-section, are of varying but very restricted length and do not extend along the full length of the fibre. As with the coresheath bicomponent fibre, this configuration is used to combine the properties of the two components. Matrix-fibril bicomponent fibres are sometimes known as 'biconstituent fibres' but the use of this term for this type of fibre is deprecated.( Sub Category of bicomponent fibre)

Matt

1. Descriptive of a surface with little or no lustre.
2. (Weaving) See hopsack.

Matt Effect

See BASKET WEAVE.

Matted Staple

Fiber in the bale that is compressed and entangled in a manner indicating that the fiber was either too wet at the baling operation or that excessive baling pressure was used.

Maturity (cotton)

A cotton fibre characteristic which expresses the relative degree of thickening of the fibre wall. It is usually estimated by one or more of several indirect tests which are often used to discover the proportion of fibres having a maturity greater than some selected level. The following termsare used in relation to cotton maturity:
(i) mature fibre: fibre where a high degree of wall thickening has taken place during cotton growth;
(ii) immature fibre: fibre where little wall thickening has taken place during growth;
(iii) normal fibre: fibre whose wall has developed to greater than a specified amount;
(iv) thin-walled fibre: fibre which doe,,, not fall into either the normal or dead categories;
(v) dead fibre: an extreme form of immature cotton.
