Chapter One:The Production Process of Sandblasted Jeans
Sandblasted jeans are crafted using a technique that involves processing denim with granular materials like sand or quartz. The production steps are as follows:
1. The jeans are loaded into a Industry washing machine
2. The machine rapidly rotates granular materials (e.g., sand or quartz), rubbing them against the jeans' surface to create wear and a gritty texture.
3. The machine is halted, and the jeans are removed for thorough cleaning and finishing.
4. Steps 1–3 are repeated multiple times to intensify the distressed appearance and gritty feel.
5. Finally, additional treatments such as bleaching, dyeing, or other finishes are applied as required.
Chapter Two:Characteristics of Sandblasted Jeans
Sandblasted jeans combine a strong vintage aesthetic with contemporary fashion appeal. Key features include:
1. Unique grit feeling and wear surface.
2. Shades of hue and color layering.
3. Stable processing results and sustainability.
4. Perfect for every occasion and collocation.
Chapter Three:History and Current Status of Sandblasted Jeans
The sandblasting technique first emerged in the 1980s. After decades of refinement, it has evolved into a timeless denim style. Today, sandblasted jeans enjoy global popularity, boasting a cult following and serving as a staple offering for many iconic denim brands worldwide.
Chapter Four:Styling and Pairing Sandblasted Jeans
Sandblasted jeans are versatile enough to pair with a wide range of wardrobe essentials, effortlessly elevating your outfit for any occasion. Below are curated styling suggestions:
1. Pair with a white T-shirt and sneakers for a relaxed, effortless vibe.
2. Team with a dark-toned hoodie and canvas sneakers to elevate the look with modern flair.
3. Combine with a metallic jacket and heels to craft a striking, individualistic style.
In Summary, Sandblasted jeans stand as a timeless yet distinctive denim style. Their universal appeal makes them a wardrobe staple for individuals of all ages and genders to express their personal style with confidence.
Chapter Five:The Salt Abrasion Process for Jeans
In the ever-evolving world of fashion, jeans have maintained an iconic status. Among their signature distressed styles, the salt abrasion technique plays a pivotal role. This method simulates natural wear by mechanically rubbing coarse salt against denim in industrial washing machines, creating authentic vintage aesthetics. The process involves five key stages: pretreatment, salt abrasion, rinsing, dewatering/drying, and quality inspection. Below is a breakdown of the workflow:
1. Pretreatment and Material Selection
Choose jeans suitable for distressing, ensuring fabric compatibility.
If jeans contain slurry (such as starch slurry), desizing treatment by industry washing machine is required first: use a mixed solution such as amylase, salt, penetrant, etc., and soak it at 50~60 °C and pH 6~7 for 30 minutes to remove the slurry and prevent streaks.
2.Core Salt Abrasion Process
Jeans and coarse salt are loaded into an industrial washing machine. Machine-driven tumbling ensures sustained friction between salt particles and the denim fabric.
The abrasive action gradually strips surface dyes, creating natural wear effects such as faded tones and micro-abrasions.
Can be combined with cellulase (acidic or neutral) to enhance the effect: acidic enzyme (pH4.5~5.5) is low cost but easy to return to color, neutral enzyme (pH6~8) is more suitable for high-grade clothing.
3.Post-Processing Stages
Rinsing: Residual salt and dye particles are removed to ensure fabric cleanliness.
Dewatering and Drying: Rapidly remove moisture through centrifugal dewatering and restore fabric softness.
Quality Inspection: Check the wear uniformity and eliminate unqualified products.
Key point: The core of the salt frying process is to achieve controlled aging through physical friction (salt grains) or chemical assistance (enzymes), which needs to balance the wear effect with the integrity of the fabric.
Chapter Six:"Salt Stir-Frying" in Denim Washing Process
"Salt stir-frying" is the common term for the desizing process in denim washing machine , referring to the pre-treatment step that uses a sodium chloride-containing formula to remove surface sizing agents from denim garments. The detailed process explanation is as follows:
1.In the desizing bath, sodium chloride is added along with amylase and acetic acid to adjust the pH to 6-7, while maintaining a temperature of 50-60°C for approximately 30 minutes.
2.Sodium chloride may serve to enhance enzymatic activity and regulate osmotic pressure during this process, facilitating the breakdown of sizing agents.
3.Following desizing, subsequent steps such as cellulase stone washing are typically performed, ultimately achieving the characteristic aged effect on denim.
Desizing Objectives: To remove sizing agents (such as starch or modified starch) from denim fabric, creating optimal conditions for subsequent washing processes.
Formulation Components: Key ingredients include amylase, sodium chloride (2-5 g/L), penetrating agents, glacial acetic acid, etc.
The process known as "stir-fried salt" is not an independent technique, but rather a colloquial term for the traditional desizing step. It primarily serves as a pre-treatment rather than directly creating the final texture of denim. In this process, it is crucial to strictly control the amount of salt used and the processing conditions to prevent adverse effects on subsequent dyeing processes or the fiber structure.
