Weaves- interlacing one or more sets of yarns at right angles on a loom a. Plain- The simplest weave in which the weft (crosswise) yarn is passed over then under each warp (lengthwise) yarn (EX: chiffon, gingham, seersucker, taffeta) b. Twill- A very strong weave in which the weft yarn is passed over and under one, two, or three warp yarns (EX: denim, chino, gabardine) c. Satin- A very weak weave that produces a smooth, shiny-surfaced fabric resulting from passing the weft yarn over and under numerous warp yarns to create long floats. (EX: sateen, satin) d. Pile- made on a loom, like most types of weaves are made. The difference is that loops are created. These loops can either be left uncut, like in towels, or can be cut to uniform lengths, like in velvet fabric. (EX: Velvet, Corduroy, Terrycloth, and Velveteen) 2.

Rib knits – have vertical “ribs” (columns of stitches), used for neck, wrist and bottom bands of sweatshirts & jackets iii. Double knits – two yarns and two needles are used resulting in heavier, sturdier knits that don’t run or ravel b. Warp: a knit made with several yarns on flat knitting machines. Multiple yarns are looped together to produce a run-resistant knitted fabric i. Tricot knits – stable knits that lie flat and don’t run or ravel, made on very fast tricot knitting machines, used for lingerie, underwear and uniforms ii. Raschel knits – an extra yarn is used to create a patterned design in these knits, used for lacy knits, thermal underwear and bathing suits c. Seamless- knitting involves the production of a whole garment in one piece on a knitting machine so that little or no sewing is required D.

Advantages include: Good for large designs, Better quality designs than roller printing method ii. Disadvantages include: Slow printing method c. Rotary screen printing- A combination of roller and screen printing. Dye is transferred through screens that roll over the fabric. i. Advantages include: Can print large designs, Accurate and fast, This method is gaining in popularity. d. Heat transfer printing- The desired dyes and patterns are placed onto paper using a rotary screen printer. The paper is placed on the fabric and with heat and pressure the colors and patterns are transferred to the fabric. T-shirts are printed using this method. Like a “temporary tattoo” for fabric. e. Digital printing- The newest method of fabric printing. It is like ink-jet printing with a computer but rolls the fabric through an extra-wide printer. Droplets of color are “spit” onto the fabric. i. Advantages include: Fast, Inexpensive, Environmentally safe, Can print small or large amounts of fabric at the same time 2.02 Understand care of textile products – Study Guide ESSENTIAL QUESTIONS 1.

What are the different seams and seam finishes and their purpose? 5. How are basic seams and seam finishes constructed? 6. What are the machine stitching techniques and their application? 7. How is bulk reduced in seams? 8. How is fullness controlled in apparel? 9. What are the different types of interfacing, characteristics, and application? 10. What are the different hem applications and how do you apply them in apparel? 11. What are the different fasteners used in constructing apparel and their proper application? OUTLINE A. Characteristics and Types of Stitches 1. Characteristics a.Standard Stitching Used for permanent seams & construction details. In most fabrics, standard stitching length is 10 to 12 inches. In finer fabrics, standard stitching is a short stitch between 12 to 15 stitches per inch. In heavy fabrics, standard stitching is a longer stitch, 8 to 10 stitches per inch. b.Basting- holds two pieces of fabric together until they are permanently stitched. Machine basting is also used on a single layer of fabric for: easing, gathering, and marking guidelines. c.Reinforcement Stitching- adds strength to areas that will be clipped or trimmed close to the stitching line or areas of high stress such as armhole, crotch and corners. There are 15 to 20 stitches per inch in a reinforced stitch. 2.Types of Machine Stitching a. Stay-stitching- Stay-stitching prevents fabric stretching. Stay-stitching is placed along bias & curved edges. Stay-stitching is added after: fabric marking, before pinning, basting or permanent stitching. b. Standard Seam Stitching- Standard seam stitching produces a 5/8 inch seam. Standard seam stitching is used in most patterns. c. Backstitching- Backstitching secures the ends of a row of stitching. To backstitch, begin ½ inch in from the end and stitch backward to the edge of the fabric. Continue sewing to other end and backstitch ½ from the end. d. Understitching- Under stitching keeps facing, or the under side of the fabric rolled out of sight. Under stitching is created from standard stitching. Stitch from right side of fabric through facing & seam allowances, 1/8 inch from seam line. e. Topstitching- Topstitching is decorative or functional stitching placed on the outside of a garment. Topstitching outlines seams, secures facings, attaches pockets, stitches pleats, and holds hems. f. Edgestitching- Edgestitching holds fabric & seams in place. It is produced by stitching ¼ from finished edge. Edgestitching is used in areas such as neck edges and zippers. g. Stitch-in-the-ditch- Edgestitching holds fabric & seams in place. It is produced by stitching ¼ from finished edge. Edgestitching is used in areas such as neck edges and zippers. h. Zigzag Stitching- Zigzag stitching is used to finish seams, stitch buttonholes; attach cording & elastic and creating decorative designs. i. Specialty Stitches- Most sewing machines have a variety of speciality stitches. Speciality stitches add a decorative aspect to a garment and can be created by a serger or sewing machine. B. Seams and Seam Finishes- Any method that stitches or trims seam allowances to prevent fraying, improve strength and apparel appearance. 1.Plain seam- The most common seam. Suitable for all areas of a garment. Not suitable for shear & lace fabrics. 2.Flat-felled seam- Self Finished Seam, Decorative, Strong, Functional, Great choice whenever raw edges are not desirable. Great seam finish for denim. 3.French seam- Self Finished Seam, Used on fabrics that ravel easily, Used so no raw edges will show, Suitable for sheer fabrics. 4.Pinked and stitched seam finish- Used on firmly woven fabrics. Extra row of stitching provides protection from raveling. 5.Zigzag seam finish- Fast, easy and quick seam finish for most fabrics. Great for knit fabrics. 6.Overlock (Serged) seam finish- Great finish for most fabrics, especially knits. Used widely in the production of apparel. 7.Turned and stitched finish- Also called hemmed or clean edge seam. Forms a narrow, single-fold hem along the edges of the seam allowance. Quick and neat method. Great seam finish for lightweight to medium-weight fabrics. C. Reducing Bulk 1. Trimming- For lightweight fabrics, Seam allowances of enclosed seams should be trimmed to an even width, usually ¼ inch. The corner of seam should be trimmed diagonally to remove extra thickness when the corner is turned. If the corner is very pointed, make an additional diagonal cut on each side of the point, trimming to 1/8 inch. 2.Grading- For heavier fabrics or places with three layers of fabric. Such as collars, cuffs etc. Always grade a seam allowance so that the widest seam allowance next to the outside of the garment. Trim to a ¼ inch and then grade to 1/8 inch. 3.Clipping- Means to make tiny clips or snips in the seam allowance every ¼ “ to ½ “. On an inward curve. Using the point of the scissors, clip to within 1/8 inch of the seam line or up to the staystitching line. 4.Notching- Means cutting tiny wedge-shaped pieces of fabric from the seam allowances. Notch on outside curves. Notch no closer than 1/8 inch to the seam line. D. Controlling Fullness 1.Darts- Triangular folds of fabric stitched to a point. Used as a shaping device to control fullness. Point to the fullest part of the body. Two basic types, single pointed and double pointed darts. 2.Casings- Fabric used to enclose drawstrings or elastic, Made be used at waistlines, sleeve edges, necklines, & hemlines. Two types: Self-casing & Applied Casings. 3.Easing- Used when two edges of fabric are slightly larger than the other. Should not cause visible gathers or pleats. Should create a smooth seam. Use for set-in sleeves, joining shoulder seams, attaching waistbands and extra fullness in hems. 4.Gathering- Tiny, soft folds of fabric formed when a larger piece of fabric is sewn to a smaller piece. Use for puffed sleeves, gathered skirts. E. Interfacing- Interfacing is a textile used on the unseen or "wrong" side of fabrics to make an area of a garment or apparel item more rigid. Adds shape & firmness to outer fabric, can add body to a belt, bag, or hat, and prevents stretching. It is used in collars, cuffs, lapels, facings, waistbands, & under buttons & buttonholes. Choose one that is the same to lighter in weight than the fabric it is being applied to. 1.Fusible- fused (dots of dried glue that ‘melts’ when heat is applied) to facings with the heat of the iron. 2.Non-fusible (Sew-in)– is usually applied to the wrong side of the garment or facing. F. Hems- A properly sewn hem: Hang straight & even, Parallel to the floor, and All fullness be eased in and sewn smoothly 1.Applying hems (marking, finishing, removing fullness, finishing) a. Mark the hem length b. Turn the hem up and press c. Finish the hem edge d. Attach the hem 2.Machine- It is the quickest, permanent hemming method. Most common methods are Topstitched, Turned & Stitched, Machine Blind Hem, and Rolled Hem. a. Topstitched: Used to attach a hem and decorate at the same time (the stitching shows, just like any topstitching). b. Turned and stitched- Looks like a topstitched hem, but the amount of fabric turned up is very small (1/4”and usually found at the bottom of a man’s shirt). c. Machine Blind Hem- Used for most commercially hemmed garments, Uses the blind hem foot. Virtually invisible. 3.Hand- The stitches should be: evenly spaced, loose enough that the fabric does not pucker, almost invisible, sewn with a single thread G. Fasteners 1.Zippers (lapped and centered)a. Lapped- A lap zipper is when a zipper is installed with a flap of fabric covering the zipper. It is used often in everything from throw pillow covers to bags to garments. The zipper type used is a standard or "all-purpose zipper" available at any sewing supply store. b. Centered- baste the area where the zipper will be attached. Center the zipper along the baste. Using a zipper foot, sew the zipper doen one side, across the actual zipper and up the other side 2.Buttons/buttonholes a. Sew through– 2 or 4“eyes” on face of button b. Shank- “hook (called a shank) on back of button 3.Snaps- Used to hold overlapping edges together where there is not much strain. Two parts – ball half and socket half. Use a double-strand of matching thread. 4.Hook & eyesa. Round eye & hook- used for neckline of dresses /shirts b. Straight eye (Bar) & hook- Straight eye (bar) & hook – use for waistbands on pants/skirts 5.Hook & Loop Tape- (AKA: Velcro) Two nylon strips that intermesh. Best way to attach is by machine, but you can buy with an adhesive back Snaps Bar & hook hook & eye (round)
