Color loss (Dye Crocking)

FACTS ABOUT COLOR

 

In many cases, the color of the garment is the primary reason for the customer's

selection. Obviously, any change or variation in the color or fading creates an

undesirable effect. Dye crocking is the result of random loss of dye or pigment due

to abrasion or mechanical action in wear or processing. When dye crocking has

occurred, the fabric appears lighter, discolored or streaked. Dyes or pigments that

crock can transfer to other parts of the garment, or to other garments that come in

contact with the garment. Dye loss and/or dye crocking can occur in any type of

wearing apparel or household fabric or home furnishing.

 Bias Cut Acrylic Knitwear

 

FABRIC FACTS

 

Acrylic Knitwear fabrics are widely used because of their light weight, soft look and

feel, which resemble wool. Acrylic knitwear is widely used for sweaters but fashion

designers and manufacturers now find growing use in dresses, blouses, skirts and

jackets. These garments can be made entirely of acrylic yarn or blended with wool

and other fibers. Manufacturers use the bias cut construction to achieve a loose,

flowing, billowing effect with better draping properties. A bias cut construction is

achieved when the garment is cut and sewn at an angle or diagonally rather than a

straight cut which gives a narrow or sheath effect to a garment.

Bonded Laminated Fabrics PDF Print E-mail

FABRIC FACTS

 

Bonding and laminating are processes that were popular several years ago. The

process had a lull for a few years, but is becoming popular again. Bonding and

lamination are a process by which two or more fabrics adhere to each other. In

technical terms, bonding is the adhesion of two fabrics (outer shell fabric to a tricot

backing fabric) and lamination is the adhesion of urethane foam to a fabric. Two

common methods for bonding and lamination are the wet adhesive and the flame

foam processes which pass through rollers. When the outer fabric is bonded to

form a puckered effect, it is referred to as matelasse. Bonding or lamination of

fabrics gives garments improved body and better appearance with little increase in

the quality and cost of the outer fabric. Bonding and lamination also stabilizes the

outer fabric, which inhibits it from shrinking. Bonded and laminated fabrics are

used for coats, raincoats, sportswear and children's wear.

Coated Furniture Fabric 

 

FABRIC FACTS

 

 Coating on furniture fabric gives the fabric several advantages. (1) The coating

prevents the smooth yarns from slipping and unraveling. (2) The coating gives the

fabric additional body and stiffness. The coating is usually rubber or latex. The

cleaner usually only receives the pillow covers as they are the only removable part.

The fact that the cover has a zipper does not mean that the manufacturer intends

that it should be removed. The zipper is for the use of the manufacturer in

obtaining a tight fit. Coated covers can be made of any fiber. Those fabrics woven

with olefin or polypropylene yarns may be sold under the trade names of Herculon,

Durel, Marvess and Vectra.
