Comprehensive Japanese-Indonesian Textile and Manufacturing Terminology

Classifications and Properties of Textile Fibers

Textile materials begin with the fundamental unit known as Serat ($\text{繊維}$ — sen'i). These are categorized primarily into Serat alam ($\text{天然繊維}$ — tennen sen'i) and Serat sintetis ($\text{合成繊維}$ — gōsei sen'i). Within the realm of natural fibers, key materials include Kapas or katun ($\text{⽊綿}$ — momen), Wol ($\text{⽺⽑}$ — yōmō), Sutera ($\text{絹}$ — kinu), and various bast fibers like Rami or linen ($\text{⿇}$ — asa) and specific Ramie ($\text{ラミー}$ — ramī). Synthetic and chemical variants include Polyester ($\text{ポリエステル}$ — poriesuteru), Nylon ($\text{ナイロン}$ — nairon), Akrilik ($\text{アクリル}$ — akuriru), Rayon ($\text{レーヨン}$ — rēyon), and Spandex or elastane ($\text{スパンデックス}$ — supandekkusu). Asetat ($\text{アセテート}$ — asetēto) is another significant chemical variant.

From a technical perspective, fibers are often grouped as Serat regenerasi ($\text{再⽣繊維}$ — saisei sen'i), which are man-made fibers from natural polymers, and the broader category of Serat kimia ($\text{化学繊維}$ — kagaku sen'i). Serat tumbuhan ($\text{植物繊維}$ — shokubutsu sen'i) explicitly refers to plant-based origins. Yarn types are defined by their construction, specifically Benang filamen ($\text{フィラメント⽷}$ — firamento shi) and Benang pintal or spun yarn ($\text{紡績⽷}$ — bōsekishi). The process of combining different fiber types is known as Blending/campuran serat ($\text{混紡}$ — konbō).

Structural Characteristics of Knitting

Rajutan ($\text{編み}$ — ami) refers to the craft and structure of knitted fabrics. Various stitch patterns define the textile's utility. The basic Rajutan jersey or plain knit ($\text{天竺編み}$ — tenjiku ami) is a foundational structure. Other common patterns include Rajutan rib ($\text{ゴム編み}$ — gomu ami), also known as Rajutan frais ($\text{フライス編み}$ — furaisu ami), and Rajutan purl ($\text{パール編み}$ — pāru ami). More complex structures include Rajutan piqué/lacoste ($\text{⿅の⼦編み}$ — kanoko ami), Rajutan interlock ($\text{インターロック編み}$ — intārokku ami), and Double knit or rajut ganda ($\text{ダブルニット}$ — daburu nitto). Technical stitch maneuvers include the Tuck stitch ($\text{タック}$ — takku) and the Float or miss stitch ($\text{フロート}$ — furōto).

In terms of fabric geometry, the vertical column is called the Wale ($\text{ウエール}$ — uēru) and the horizontal row is the Course ($\text{コース}$ — kōsu). The density and quality of the knit are measured by Stitch density ($\text{度⽬}$ — domoku), Stitch length ($\text{編み込み⻑}$ — amikomicho), and Gauge ($\text{ゲージ}$ — gēji), which counts the number of needles per inch. The physical weight of the fabric is expressed as Berat kain ($\text{⽬付}$ — metsuke) in units of $g/m^2$. Manufacturing issues commonly encountered include Skewing ($\text{斜⾏}$ — shakō), Curling ($\text{カーリング}$ — kāringu), and Pilling ($\text{ピリング}$ — piringu). The term Cut and sew ($\text{カットソー}$ — katto sō) refers to the process of cutting knitted fabric and sewing it into garments.

Knitting Machinery and Component Engineering

Industrial knitting utilizes the Mesin rajut bundar ($\text{丸編み機}$ — maru amiki). Core components include the Silinder ($\text{シリンダ}$), the Dial ($\text{ダイヤル}$), and the Sinker ($\text{シンカ}$). The Cam ($\text{カム}$) controls the needle movement, while the Yarn feeder or mouth of the supply ($\text{給⽷⼝}$ — kyūshikō) delivers the thread. Needles ($\text{針}$ — hari) are typically Latch needles ($\text{ラッチ針}$ — ratchibari), consisting of the Lidah or latch ($\text{ベラ}$ — bera) and the Hook ($\text{フック}$ — fukku). Precision is managed via the Seleksi jarum ($\text{選針}$ — senshin) and the Perangkat tegangan ($\text{テンション装置}$ — tenshon sōchi).

Yarn measurements are critical for machine settings. These include Nomor benang or count ($\text{番⼼}$ — bante), Denier ($\text{デニール}$ — denīru), and Desitex ($\text{デしてっくす}$ — deshitekkusu / dtex). The physical properties of the yarn include Puntiran or twist ($\text{撚り}$ — yori), which is categorized as Puntiran S ($\text{S撚り}$ — esu yori) or Puntiran Z ($\text{Z撚り}$ — zetto yori). Combining multiple yarns is known as Plying ($\text{合⽷}$ — gōshi), and machine maintenance requires Minyak pelumas ($\text{潤滑油}$ — junkatsuyu).

Fundamentals of Sock Production and Design

Kaus kaki ($\text{靴下}$ — kutsushita) manufacturing involves specific anatomical parts: the Waistband/elastic top ($\text{⼝ゴム}$ — kuchigomu), Tumit ($\text{踵}$ — kakata), Ujung jari kaki ($\text{⽖先}$ — tsumasaki), and Sol or telapak kaki ($\text{⾜底}$ — ashizoko). Specialized footwear includes Pantyhose ($\text{パンティストッキング}$ — panti sutokkingu) and Knee-length socks ($\text{ニーレングス}$ — nī rengusu). Technical knitting methods like Plating knitting ($\text{プレーティング編み}$ — purētingu ami) utilize two different yarns: the Benang muka ($\text{表⽷}$ — omote ito) and the Benang belakang ($\text{裏⽷}$ — urai ito).

Yarn types used in socks include Covered yarn ($\text{カバードヤーン}$), Woolly nylon yarn ($\text{ウーリーナイロン⽷}$), and Benang karet ($\text{ゴム⽷}$). Toe closure is achieved through processes like Linking ($\text{リンキング}$) or Rosso ($\text{ロッソ}$). Decorative patterns are created using Rajutan jacquard ($\text{ジャカード編み}$), Pola spiral ($\text{スパイラル柄}$ — supairaru gara), or Pola links ($\text{リンクス柄}$ — rinkusu gara). Industrial production may use a Silinder ganda ($\text{ダブルシリンダ}$) or a Latch guard ($\text{ラッチガード}$).

Dyestuffs and Chemical Auxiliaries in Textiles

Dyeing involves applying Pewarna ($\text{染料}$ — senryō) or Pigmen ($\text{顔料}$ — ganryō). Specific dyes are chosen based on fiber types: Pewarna reaktif ($\text{反応染料}$), Pewarna asam ($\text{酸性染料}$), Pewarna dispersi ($\text{分散染料}$), Pewarna langsung ($\text{直接染料}$), Pewarna kationik ($\text{カチオン染料}$), Pewarna vat ($\text{建染め染料}$), and Pewarna metal complex ($\text{⾦属錯塩染料}$). Leveling dyes ($\text{レベリング染料}$) are used to ensure uniformity.

Essential chemicals include Natrium hidroksida ($\text{⽔酸化ナトリウム}$ / NaOH), also known as Soda kaustik ($\text{苛性ソーダ}$), and Natrium sulfat ($\text{硫酸ナトリウム}$), known internally as Glauber's salt ($\text{芒硝}$ — bōshō). Oxidation and bleaching often use Hidrogen peroksida ($\text{過酸化⽔素}$ / $H_2O_2$). Chemical agents used to manage the dyeing bath include the Leveling agent ($\text{均染剤}$ — kinsenzai), Retarding agent ($\text{緩染剤}$ — kansenzai), Mordant ($\text{媒染剤}$ — baisenzai), Carrier ($\text{キャリヤー}$), and Agen anti-busa ($\text{消泡剤}$ — shōhōzai).

Evaluations involve gauging Color change ($\text{変退⾊}$) and Staining ($\text{汚染}$ — osen) using the Blue scale ($\text{ブルースケール}$) and Grey scale ($\text{グレースケール}$). Color is mathematically defined by Hue/corak ($\text{⾊相}$ — shikisō), Lightness/kecerahan ($\text{明度}$ — meido), and Saturation/kejenuhan ($\text{彩度}$ — saido). Colors lacking saturation are Warna akromatik ($\text{無彩⾊}$ — musaishoku).

Visual perception is influenced by the Source of light ($\text{光源}$ — kōgen), with Jendela utara ($\text{北窓}$ — kita mado) serving as a standard northern light window source. Metamerisme ($\text{メタメリズム}$) refers to color matching challenges under different lighting. Laboratory factors include the pH/degree of acidity ($\text{ぴーえいち}$), where pH $7$ is Netral ($\text{中性}$ — chūsei). Scientific processes include the creation of a Larutan ($\text{溶液}$ — yōeki) through Pelarutan ($\text{溶解}$ — yōkai), as well as the chemical breakdown known as Hidrolisis ($\text{加⽔分解}$).

Key quality metrics for bedding are Jahitan ($\text{縫い⽬}$), Stitch length ($\text{⽷⽬}$ — itome), Daya serap kelembapan ($\text{吸湿性}$), and Sirkulasi udara ($\text{通気性}$).

Occupational Safety and Workplace Hygiene Standards

Safety management centers on the distinction between Keselamatan ($\text{安全}$ — anzen) and Bahaya ($\text{危険}$ — kiken). Workers must use APD/Personal Protective Equipment ($\text{保護具}$ — hogogu), including Masker pelindung ($\text{防護マスク}$), Sarung tangan karet ($\text{ゴム⼿袋}$), and Kacamata pelindung ($\text{保護眼鏡}$). Electrical safety is paramount to prevent Sengatan listrik ($\text{感電}$ — kanden) and Kebocoran arus ($\text{漏電}$ — rōden), requiring Grounding ($\text{アース}$), Sekering/fuse ($\text{ヒューズ}$), and Safety valves ($\text{安全弁}$).
